Gravitational Redshift & Expanding Spherical Wavefronts

An earlier post on Expanding Spherical Wavefronts made a qualitative argument that an ESW should sustain an energy loss as it expands through the Cosmos. In a more recent post it was argued that gravitational effects are a consequence of matter/electromagnetic-radiation interactions. As a follow-up, this post offers a quantitative demonstration that standard gravitational-redshift-based-math can be applied to an ESW to generate a cosmological redshift correlated with distance:

Terms & Definitions:
z = ((1-(rs/Resw))^(-1/2))-1
rs = Schwarzschild radius = 2GM/c²
Res = successive radii for an Expanding Spherical Wavefront in lightyears
Resw = successive radii for an ESW in meters
M = Calculated mass for a sphere at selected radii, assuming an average cosmological density of 1E-26 kg/m³. The average density is a free parameter in the model but the results are highly sensitive to this particular value. A variation of +/- 10% produces outcomes that seem unrealistic.

All in all, this is nothing more than a proof of concept – but it is an intriguing one. Two pieces of standard physics can be put together to produce a cosmological redshift-distance relation that is similar to the one presented by the standard model. The three graphs of redshift-distance are taken from the table and illustrate scale differences over the range of the table. A short discussion follows the 3rd graph.

Discussion

There are several interesting aspects to these results. The initial radius of 75M lightyears is arbitrary and lies just inside the 100Mly radius that can be considered to encompass the “local” Cosmos. The final radius is in the asymptotic range imposed by the math.

What is happening in the math is the Schwarzschild radius (rs) is catching up with the Expanding Spherical Wavefront being modeled. This is because the rs is increasing in proportion to the enclosed mass which is increasing as Resw³ while the ESW itself is only increasing as Resw². This is the inverse of what happens (according to the Schwarzschild solution to GR) in the case of a mass undergoing gravitational collapse. In that situation the collapsing body converges inward toward the rs as the mass remains constant.

It should be noted that the rs is an artefact of the model; it is a coordinate singularity and not physically significant. This indicates that the model has broken down at that point by virtue of having produced a division by zero result. It can be argued that this is a consequence of the model not taking into account the variation in the speed of light in a gravitational gradient.

It is also striking that the redshift of the ESW model goes asymptotic at approximately the same cosmological distance (13.4Gly) that the standard model redshift does (13.8Gly). The difference is that in the ESW model the redshift is a consequence of the energy loss to the expanding spherical wavefront attributable to its gradual absorption by intervening galaxies. In the standard model the energy loss is a consequence of a model-inferred but unobservable “universal expansion” – which leaves the lost energy physically unaccounted for.

One other point of note, in the ESW account of redshift the cosmological conditions at the source of the redshifted light are assumed to be approximately the same as they are in our “local Cosmos”. In the standard model, of course, the cosmological conditions at the largest implied redshift distances are thought to be significantly different due to the nature of the evolving “expanding Universe” that the model assumes. The recent JWST observations contradict the standard model’s picture of an evolving “Universe”.

It is not polite to discuss DWRT

I recently commented on an astrophysicist’s blog regarding a claim I consider ahistorical and inaccurate. The comment was deleted. I don’t have a problem with that – a blog is a personal space. However, I was responding to a specific claim about the origin of General Relativity that is both common and false. What follows is the one paragraph remark I was commenting on and my now-deleted response which admittedly ranges a bit further than simply refuting the quote requires:

The equivalence of inertial mass with gravitational charge is a foundational principle of general relativity. There are flavors of GR in which it falls out explicitly, e.g., Yilmaz’s gravity. But it is basically an assumption.

The equivalence of inertial and gravitational mass was an observed and measured fact known to Galileo and Newton. It was not an assumption of GR. The mid-20th century extensions of what is now called the Weak Equivalence Principle were little more than conjectures of mathematical convenience “suggested” by Robert H. Dicke. They had nothing to do with the development of GR.

Along with John A. Wheeler’s aphoristic, empirically baseless, invocation of a causally interacting spacetime, Dicke’s two extensions of the WEP were surreptitiously hung on Einstein’s General Relativity producing a grotesque variant that by rights should be known as Dicke-Wheeler Relativity Theory. It is DWRT that has been the officially taught version for the better part of 50 years although the D-W distortions are almost always attributed to Einstein. He would have puked.

It is DWRT that prompts otherwise rational people to insist that, despite theoretical and empirical evidence to the contrary, the speed of light is some sort of universal constant. It is DWRT that promotes the false claim that Einstein explained gravity as being caused by the curvature of space.

As far as space itself goes, it is a relational concept exactly like distance. That is all the evidence supports. In fact, space is best understood as the aggregate of all distances that separate you from all the other things in the Cosmos that aren’t you. Substantival space is a mathematicist fiction that has no scientific basis.

Throughout the Cosmos, everywhere within our observational range where there is no matter there is only electromagnetic radiation. That is an empirical fact. Everywhere people imagine they see space there is electromagnetic radiation. At any given 3D location that radiation is flowing omnidirectionally from all the omnidirectional emitters (stars and galaxies) within range. That is what we observe and that is how we observe.

As Mach surmised we are connected to the rest of the Cosmos or at least to those objects within range. That non-simultaneous connection is via electromagnetic radiation – that is what’s there. Until recently no one had bothered to do a full survey of what might be called the Ambient Cosmic Electromagnetic Radiation. The authors of this interesting paper seem to think they are the first. Everybody else was too busy looking for some dark stuff apparently.

Modern theoretical physics is all theory and no physics; it consists of nothing but the unrelenting and fruitless effort to prop up two inert century old models whose assumptions of mathematical convenience were lapped by physical reality decades ago. Tinkering with obsolete mathematical models does not constitute a scientific endeavor even if that is all that has been taught for the last 40 years.

Inertia, Gravity, & Electromagnetic Radiation

This very interesting paper originally caught my attention because it demonstrates that Einstein rejected what the paper calls the “geometrization” of gravity and did so throughout his career not just at the end of his life. On a recent rereading I was struck by something else which is easy to forget – the subtly of Einstein’s thought.

The geometrization of gravity is an awkward term because it elides the central problem which is the reification of spacetime. It is well known that Einstein’s Relativity Theory employs the geometric math of Gauss-Riemann. What is at issue is whether that geometric math refers to a physical spacetime that causally interacts with matter and energy (electromagnetic radiation). Many argued that it did while Einstein rejected that interpretation as unphysical and uninformative.

Beyond the issue of what Einstein did not believe, the paper illuminates a seldom discussed subject – what Einstein did believe Relativity Theory accomplished, the unification of gravity and inertia. This unification is not found in the famous gravitational equation of General Relativity but in the lesser known geodesic equation. From the paper:

“We found that (i) Einstein thought of the geodesic equation in GR
as a generalisation of the law of inertia; (ii) in which inertia and gravity
were unified so that (iii) the very labeling of terms as ‘inertial’ and
‘gravitational’ respectively, becomes in principle “unnecessary”, even if
useful when comparing GR to Newtonian theory.“

While it is well understood that the Equivalence Principle* played a role in Einstein’s thought process while developing GR the importance of the geodesic equation as a formal realization of the EP is certainly not widely acknowledged as far as I am aware. The implications of that unification are profound.

One of the peculiarities of the modern theoretical physics community is their apparent disinterest in determining the physical cause of the gravitational effect. The reason for this disinterest is a philosophical attitude known as instrumentalism – if some math describes an observed outcome adequately then a causal explanation is superfluous. Instrumentalism is a variant of the scientifically baseless philosophical belief called mathematicism.

The purpose of science is to investigate the nature of physical reality, not to sit around fiddling with poorly constructed mathematical models of physical reality that do not remotely make sense when you inquire of the model, What does the math mean with regard to the physical system being modeled? The answer that typically comes back is a peculiar kind of bullshit that can be thought of as Big Science Babble.

Superposition Of States is Exhibit A of BSB on the quantum scale. Almost all quantum scale babble winds up at SOS or at Wave-Particle Duality. SOS tells us that an electron is never at a particular position until it is observed.

When an electron is detected it is always, not surprisingly, at a particular location but according to the mathematicists at all other times when not being observed the electron is in a SOS – it is spread out over all of its possible locations as described by some math (the wavefunction). How do they know this? Because the math doesn’t know where the electron is, so it can’t be anywhere in particular. Sure, of course.

BSB is rife on the cosmological scale. According the standard model of cosmology the Cosmos is 95% made up of some invisible stuff while the stuff we actually observe provides the remaining 5%. How do scientists know this invisible stuff is there? Because it has to be there to make the Big Bang model work and everybody knows the BB model is correct because they said so in graduate school, so the invisible stuff has to be there, like it or not. Sure, of course.

At the root of all BSB, of course, is mathematicism. A mathematical model dictates an absurd story about physical reality which we are then supposed to believe without evidence because math determines the nature of physical reality. If mathematicists with pieces of paper saying they are scientists believe in BSB, shouldn’t you? No, you should not.

Physical reality is an afterthought to mathematicists for whom only math is of interest. That’s why no effort is being expended in the scientific academy to understand the physical cause of gravity; research funding is controlled by mathematicists. And since they already have some math that kind of works (as long as reality contains things it does not appear to contain), well that’s good enough – for mathematicists.

In real science, physical events and behaviors occur as a consequence of physical interactions. Those interactions can be matter/matter (collision), matter/radiation (emission, absorption, reflection), or radiation/radiation (interference) in nature. There is a good argument to be made that all observed gravitational and inertial effects arise as a consequence of matter/radiation interactions:

By observation, everywhere in the Cosmos that there is no matter, there is electromagnetic radiation.
Light traversing a gravitational field behaves as it does in a transparent medium with a density gradient. All approximately spherical gravitating bodies emit electromagnetic radiation omnidirectionally with a density gradient that falls off as 1/r².
The gravitational effect surrounding a spherical gravitating body falls off as 1/r².
The gravitational field then is just the Ambient Local Electromagnetic Radiation field surrounding a gravitating body.
In the intergalactic regions, far from any significant gravitating bodies there is only the ubiquitous Ambient Cosmic Electromagnetic Radiation.
The ACER is, to a good approximation, isotropic and this cosmically sourced electromagnetic field does not have a density gradient. It can be thought of as the inertial field.
This unified physical account of gravity and inertia is consistent with Einstein’s mathematical description of a unified gravity and inertia in the geodesic equation.**

*The Equivalence Principle Einstein employed is now known, since the mid 20th century, as the Weak Equivalence Principle to distinguish it from later, dubious extensions, added with little scientific justification after Einstein’s death in 1955.

**The forgoing does not constitute conclusive evidence that gravity is an effect of matter/electromagnetic-energy interactions – but it is evidence based on empirical observations. In contrast, there is no empirical evidence for the concept of gravity as a fundamental force.

Forces are themselves not things, they are effects. Of the four fundamental forces claimed by science to exist, only the electromagnetic force has any empirical basis. In fact though electromagnetic radiation is no more a “force” than a golf club is a “force”.

A golf club exerts a force on a golf ball by striking it, resulting in an acceleration of the ball. That applied force can be quantified using known mechanical laws. The term force describes that interaction but force is just a descriptive term for the interaction between the golf club and golf ball, it is not the golf club nor is it a separate thing in itself. The same analysis applies to EMR; it is not a force but it can exert a force when it strikes a physical object.

Groupthink, Dogma & Inertia

Re: this Ethan Siegel article.

“If we ever want to go beyond our current understanding, any alternative theory has to not only reproduce all of our present-day successes, but to succeed where our current theories cannot. That’s why scientists are often so resistant to new ideas: not because of groupthink, dogma, or inertia, but because most new ideas never clear even the first of those epic hurdles, and are inconsistent with the established data we already possess.“

Strangely enough that is a pretty good description of why modern theoretical physics appears to be in fact quite dogmatic and inert. If new ideas can be dismissed for not immediately clearing the “epic hurdles” that theorists prescribe, then they amount to nothing more than preemptive barriers to new ideas. This greatly favors the orthodoxy.

No research funding is available for new ideas that don’t hurdle the barriers. They function as a defensive bulwark protecting the standard model from unorthodox incursions.

The only new ideas that are quickly adopted are those that fit the old model to new data. The favored model can be continuously revised (new epicycles, dark matter, etc.) into agreement with unpredicted new data. The “epic hurdles” only apply to new ideas that challenge the orthodoxy. New ideas needed to salvage the old model are adopted without reservation.

And so here we are, stuck with a cosmological model that is in an exactly analogous situation to that which existed with respect to Ptolemaic Cosmology prior to Kepler. Ptolemy’s model could be massaged into agreement with most observations and repeatedly tinkered into agreement with new, more accurate data, but only to some degree. So it is with the Big Bang model. Math is like that, but math is not physics.

Like PC, the BB model has at its core two fundamental misperceptions about the nature of physical reality. PC assumed geocentrism and that bodies orbited the earth in perfect circles. Only once geocentrism and perfect circles were set aside could science advance.

The two misperceptions underlying the BB are first, that the Cosmos can be mathematically modeled as a simple, unitary, simultaneously-existing entity – a Universe. Secondly, the observed cosmological redshift can be attributed to some form of recessional velocity. The inevitable consequence of those assumptions is an Expanding Universe model – the BB.

The first assumption has been falsified by known physics. The speed of light has a finite maximum such that it requires light from the most distant objects we currently observe more than 10 billion years to reach us. It therefore follows that we have no knowledge of the simultaneous state of the Universe because it is physically impossible to have such knowledge. It is a metaphysical conceit, not a demonstrable scientific fact, that such a Universe even exists.

The second assumption is false because it depends on the first being true. It is meaningless to assume something that requires something that does not exist (the Universe) to have a property (expansion) that cannot possibly be observed.

As was the case in Kepler’s time, the only solution to the dogmatic inertia that cripples modern cosmology is to discard the foundational assumptions of the standard model and start over, by rigorously assessing the data on hand without the distorting blinders of the old model.

Over the last century there has been an enormous increase in our knowledge of the Cosmos but due to the dogmatic inertia of the scientific academy all of that new knowledge has not generated any new ideas because it has all been run through the meat-grinder of the standard model. The result has been a dogmatic and inert BB model that describes in excruciating detail a Universe that does not exist and bears no resemblance to the Cosmos we actually observe.

Kepler had an advantage that modern researchers do not – he was not dependent on the dogmatic and inert modern scientific academy for funding. Modern cosmology will remain an unscientific digression into prescientific orthodoxy until it’s research funding is driven by the physics researchers investigating, by observation and measurement, physical reality.

Theoretical modelers in such a system would be required to produce models that reflect the physical phenomenon uncovered by physics researchers. The math must follow the physics if cosmology is to be a science.

The failed Big Bang model needs to be consigned to the dust bin of history where it can serve as an object lesson in how not to do science.

Mathematicist Follies & the DWRT

Leave a reply

Here are some choice tidbits from a recent Tim Anderson article titled Zero-point energy may not exist. I’m always supportive of any effort to drag theoretical physics back into contact with empirical reality so the suggestion that ZPE may not exist is at least promising. It even suggests the possibility that modern theoretical physics might emerge from its self-imposed exile in Plato’s cave, the cave-of-choice in this case being mathematicism.

In reading the article any hope of a scientific restoration is dashed, as one is quickly immersed in sea of mathematicist illogic. Here for instance is the “reasoning” that underlies the ZPE concept:

…it means that nothing has non-zero energy and because there is an infinite amount of nothing there must be an infinite amount of energy.

While it is clear that the author is distancing himself from the ZPE concept, that account of the underlying “reasoning” gives rise to the simple question, how did such flamboyantly illogical nonsense gain any traction in the scientific community? The answer of course is mathematicism which is itself a flagrantly illogical proposition, just not recognized as such by the denizens of the mathematicist cave. Then there is this little gem (emphasis added):

Quantum field theory, which is the best theory of how matter works in the universe that we have, suggests that all matter particles are excitations of fields. The fields permeate the universe and matter interacts with those fields in various ways. That is all well and good of course. We are not questioning that these fields exist. The question is whether a field in a ground state has any measureable effect on matter.

So in their “best theory” the universe is permeated by many fields and matter is an excitation of those fields. Physical reality however only contains one observed field and that is the electromagnetic field which is the aggregate of all the electromagnetic radiation that permeates the Cosmos. That radiation is constantly being emitted by all the luminous matter that also permeate the Cosmos. There are no additional observed fields as described by QFT.

Despite the fact that the QFT fields are not observed the author does not wish to question their existence. Why? Mathematicism, of course. If a math model says something is there and physical reality declines to offer any evidence in support of such a conjecture, the mathematicist position is that the math is correct and reality is perversely withholding the evidence.

Imagine we have a sensitive Hawking radiation detector orbiting a black hole. The detector is in a state of free fall, meaning that it experiences no gravitational forces on it.

This last bit invokes a wholly imaginary thought experiment involving imaginary radiation emitted by an imaginary black hole. Without any empirical basis or logical connection to known physics, it has no scientific significance even if the “experiment” somehow reflects badly on the ZPE concept. In that, it only amounts to an illogical argument refuting an illogical concept.

The second sentence also presents a widely promulgated claim that has no basis in physics. The idea that an observer or detector in free fall experiences no gravitational forces on it is purely unphysical nonsense. An observer or detector can only be in a state of free fall if they are experiencing a gravitational force. The typical basis for this claim is that the observer is prohibited from making observations that would clearly show the presence of a gravitating body and thus demonstrate the presence of a gravitational field.

Einstein is usually credited with this view but in fact his conception of the equivalence principle was highly constrained and did not extend to fundamentally illogical claims like the one made above. The version of the equivalence principle Einstein employed is now called the Weak Equivalence Principle.

The two extensions of the equivalence principle contrived and adopted after Einstein’s death, the disingenuously named Einstein EP (he had nothing to do with it) and the Strong EP have no logical, scientific or theoretical justification. They were merely conjectures of mathematical convenience proposed by the physicist Robert H. Dicke, who along with his colleague John A. Wheeler, concocted a distorted variant of Einstein’s Relativity Theory. That variant is presented today as Einstein’s RT but it is a separate theory and should have it’s own name — Dicke-Wheeler Relativity Theory.

It is in DWRT that you will find the EEP and SEP as well as a reified version of spacetime which is said to causally interact with matter and energy causing the gravitational effect and facilitating the Expansion of the Universe. There is no empirical evidence supporting those ad hoc additions to ERT. They are simply mathematicist conjectures that have no scientific basis or logical connection to physical reality. In modern theoretical physics though, they are treated as axioms — true by definition.

Mathematicism is the principle driver of the Crisis in Physics. The reason for this is simple: math is not physics. The controlling paradigm in modern theoretical physics, however, is that math is the basis of physics and mathematical models determine the nature of physical reality. That paradigm is a philosophical belief that has no scientific basis.

As a consequence of mathematicism theoretical physicists espouse two standard models that describe a physical reality containing a large number of entities and events that are not part of the physical reality we actually observe. Modern theoretical physics does not constitute a science so much as a cult of belief.

You have to believe in the expanding universe, in dark matter and dark energy, in quarks and gluons. You have to believe that the speed of light in a vacuum is a universal constant even though it cannot be measured as such and is not constant in General Relativity — at least according to Einstein.* You have to believe in these things because they are not demonstrably part of physical reality. Scientists don’t traffic in beliefs but mathematicists do and so there is a Crisis in Physics

* The speed of light is a universal constant according to Dicke-Wheeler Relativity Theory.

Denial Of The Deluded

Leave a reply

The New York Times has a recent guest article entitled The Story of Our Universe May Be Starting to Unravel. It is in some ways good to see doubts about the Standard Model of Cosmology surfacing in the mainstream press. What the authors, an astrophysicist and a theoretical physicist, have on offer though is some weak tea and a healthy dose of the usual exculpatory circular reasoning.

The authors do point out some of the gaping holes in the SMoC’s account of the Cosmos:

“normal” matter — the stuff that makes up people and planets and everything else we can see — constitutes only about 4 percent of the universe. The rest is invisible stuff called dark matter and dark energy (roughly 27 percent and 68 percent).
Cosmic inflation is an example of yet another exotic adjustment made to the standard model. Devised in 1981 to resolve paradoxes arising from an older version of the Big Bang, the theory holds that the early universe expanded exponentially fast for a fraction of a second after the Big Bang.

That’s a start I guess but then we get this absurd rationalization for simply accepting the invisible and entirely ad hoc components of the SMoC:

There is nothing inherently fishy about these features of the standard model. Scientists often discover good indirect evidence for things that we cannot see, such as the hyperdense singularities inside a black hole.

Let’s be clear here about this so-called “indirect evidence“; all of it essentially boils down to model dependent inference. Which is to say, you cannot see any evidence for these invisible and/or impossible (singularities) things unless you peer through the distorting lenses of the simplistic mathematical models beloved of modern theoretical physicists. People who believe that mathematical models determine the nature of physical reality are not scientists, they are mathematicists and they are deluded – they believe in things that, all the evidence says, are not there.

Not only are mathematicists not scientists, they are not good mathematicians either. If they were good at math and found that one of their models was discordant with physical observations they would correct the math to reflect observations. What mathematicists do is correct reality to fit their math. That is where the dark sector (dark matter & dark energy) come from – they added invisible stuff to reality to make it fit their broken model.

A mathematician did come up with a correction to Newtonian dynamics that had been inaccurately predicting the rotation curves of disk galaxies. Mordehai Milgrom developed MOND (Modified Newtonian Dynamics) in the 1980s and it was quite successful in predicting galactic disk dynamics.

Unfortunately the mathematicists had already off-loaded their problem onto reality by positing the existence of some unseen dark matter. All you have to know about the state of modern theoretical physics is that after 40 years of relentless searching and failure to discover any empirical evidence there remains a well-funded Dark Matter cottage industry, hard at work seeking evidence for the non-existent. This continuing search for that which is not there represents a betrayal of science.

It might appear that the authors here are not mathematicists given that they seem to be suggesting that the SMoC is not sacrosanct and needs to be reconsidered in its entirety:

We may be at a point where we need a radical departure from the standard model, one that may even require us to change how we think of the elemental components of the universe, possibly even the nature of space and time.

Sounds promising but alas, the reconsideration is not to be of the foundational assumptions of the model itself but only certain peripheral aspects that rest on those assumptions such as “…the assumption that scientific laws don’t change over time.” Or they suggest giving consideration to to this loopy conjecture: “…every act of observation influences the future and even the past history of the universe.“

What the authors clearly do not wish to reconsider is the model’s underlying concept of an Expanding Universe. That assumption – and it is only an assumption of the model – was adopted 100 years ago at a time when it was still being debated whether the galaxies we observed were a part of, or separate from, the Milky Way. It was, in other words, an assumption made in ignorance of the nature and extent of the Cosmos as we now observe it. The authors treat the Expanding Universe concept as though it had been handed down on stone tablets by some God of Mathematicism:

A potent mix of hard-won data and rarefied abstract mathematical physics, the standard model of cosmology is rightfully understood as a triumph of human ingenuity. It has its origins in Edwin Hubble’s discovery in the 1920s that the universe was expanding — the first piece of evidence for the Big Bang. Then, in 1964, radio astronomers discovered the so-called Cosmic Microwave Background, the “fossil” radiation reaching us from shortly after the universe began expanding.

For the record, Edwin Hubble discovered a correlation between the redshift of light from a galaxy and its distance. That is all he discovered. It is an assumption of the model that the redshift is caused by some form of recessional velocity. It is also an assumption of the abstract mathematical physics known as the FLRW equations that the Cosmos is a unified, coherent, and simultaneously existing entity that has a homogenous and isotropic matter-energy distribution. Both of those assumptions have been falsified by observations and by known physics.

Also for the record it should be noted that prior to the discovery of the Cosmic Microwave Background Radiation predictions by Big Bang cosmologists ranged over an order of magnitude that did not encompass the observed 2.7K value. At the same time scientists using thermodynamic considerations made more accurate predictions.

The belief in an Expanding Universe has no scientific basis. It is a mathematicist fantasy, and until that belief is set aside, the Standard Model of Cosmology will remain a crappy, deluded fairy tale that does not in any objective way resemble the magnificent Cosmos we observe.

Spherical Wavefronts & Cosmological Reality

Expanding Spherical Wavefronts are standard physics:

Credit: Gong Gu, https://fr.slideserve.com/oster/ece341-electromagnetic-fields-powerpoint-ppt-presentation

The Expanding Spherical Wavefronts depicted above are physical entities. They illustrate the behavior of light as emitted omnidirectionally by a “point source” emitter. Point source, as always in physics, is a mathematical term of art, there being no physical meaning to the mathematical concept of a dimensionless “point”. A source can be treated mathematically as point-like, however, for an observer distant enough that the emitting source’s dimensions are small relative to the radial distance to the observer.

In the foregoing sense, a typical galaxy can be treated as a point source at large ( >100 million lightyears) distance. The nested shells of the model can be considered as representing either successive positions of a single wavefront over time or an instantaneous representation of continuously emitted successive wavefronts from a typical, omnidirectional emitter such as a galaxy.

This nested shell model can also be invoked to illustrate a ubiquitous inverse electromagnetic phenomenon. Replacing the emitter with an observer, the nested shells can be seen as representing notional spheres existing at various, arbitrary radial distances from the observer. At any given radial distance of cosmological significance from the observer the notional shell will have on it some number of galaxies. Such a notional shell also defines a notional volume which must also contain some number of galaxies. This geometrical situation is only relevant to the observer; it is not, as in the ESW case, a physical entity.

Elaborating a bit, we can define a cosmological radial unit of r = 100 million lightyears. That radial unit then defines a sphere with a surface area proportional to r² and a volume proportional to r³, For illustrative purposes we make a simplifying (and unrealistically low) assumption that any r³ unit volume contains on average 1000 galaxies.

Observers whose observational range extends out 1 radial unit will observe their “universe” to contain 1000 galaxies. If those same observers improve their technology so that their range of observation extends to 2 radial units they will find themselves in a “universe” that contains 8000 galaxies. If their range doubles again to 4r their “universe” will now contain 64,000 galaxies.

Every time the observational range doubles the total number of galaxies contained in the newly expanded “universe” will increase by a factor of 8 or 2³. Of that 8-fold increase 7/8 of the total number of galaxies will lie in the newly observable portion of the total volume. This all follows from straightforward geometrical considerations.

Now let us return to the shell model centered on an omnidirectional emitter. The same geometric considerations apply here but this time with respect to an Expanding Spherical Wavefront. At 1r a wavefront will have encountered 1000 galaxies, at 4r, 64,000 galaxies and at 8r it will have encountered a total of 512,000 galaxies. As mentioned earlier, these numbers may be unrepresentative of the actual number of galaxies encountered, which could be considerably higher.

When an ESW encounters a galaxy some portion of that wavefront is absorbed by the galaxy representing a loss of energy by the wavefront and a corresponding gain of energy by the galaxy. This leads to two further considerations, the first related to direct observations. An ESW will lose energy as it expands in proportion to its volumetric expansion assuming a constant average galactic density . The energy loss will be be insignificant for each individual galactic encounter but the aggregate loss will increase exponentially at large radial distances. An increasing loss of energy with distance is an observed fact (cosmological redshift) for the light from galaxies at large (>100Mly) cosmological distances.

The second consideration is that in some finite time period relative to the emitter all of an ESW’s energy will be absorbed by intervening galaxies (and any other non-luminous baryonic matter). The cosmological range of an ESW is inherently limited – by standard physical considerations. In a sense, their is a notional cosmic wall, relative to the emitter, beyond which its ESWs cannot penetrate.

Reverting once again to the observer’s point of view, it follows that the observers cannot receive electromagnetic signals from sources that have reached the limits of their range – the cosmic wall discussed in the previous paragraph. It also follows directly that the observer is surrounded by a notional cosmic wall, relative only to the observer, beyond which more distant emitters cannot be observed. This wall has no physical significance except from the observer’s local Point-Of-View – it is the aggregate of all the ESW notional walls that surround the observer.

That notional wall is real however in the sense that it defines the limits of any observer’s observational range, just as the wall encountered by an ESW limits the range of its expansion. In both cases we are dealing with a relativistic POV. The ESW just before it reaches its wall encompasses an enormous cosmological volume relative to its source emitter’s location. Observers, just before encountering their notional wall, observe an enormous cosmological volume relative to their three dimensional locale.

Keeping in mind the earlier discussion of the spherical geometry of ESWs, it is interesting to consider that immediately in front of an observer’s notional wall there lies a vast volume of some nominal thickness containing galactic emitters that are still observable. The number of those emitters has increased as R³, while their cosmological redshift has increased as R³, where R is the observer’s radial distance from the remote sources. Beyond that radial distance lies the notional wall at which all observations cease. In that context the observer’s wall can be thought of as a concave, spherical shell against which all foreground observations are projected. Because of the geometrical considerations mentioned, we should expect the most distant visible galaxies to cover the notional, concave, spherical surface of the observer’s cosmological view.

What we arrive at then is a picture much like that proposed by Olber’s Paradox, the only difference being that Olber did not account for the energy loss of light so he expected that the night sky should be uniformly bright in the visible spectrum. What we observe, of course, is a night sky uniformly bright in the microwave spectrum.

The existence of the Cosmic Microwave Background is consistent with the galaxy distribution and energy loss to be expected by using the Expanding Spherical Wavefront framework of standard physics to model the Cosmos we observe. The only assumptions necessary to achieve this result are of an average galactic density on cosmological scales and that the field of galaxies extends sufficiently far for the geometrical arguments to hold.

The Self-Deluded Nature of Modern Cosmology

Leave a reply

In a discussion over at ACG, Louis Marmet recently posted this 2022 paper by the cosmologist James Peebles. It is, in essence, another apologia for the current mess in theoretical cosmology offered by one of the prominent purveyors of that mess. The paper is a hot cauldron of disingenuous argumentation based on the usual mathematicist predilection for circular logic that always begins with the premise that the standard model is correct only to arrive at the same conclusion.

Rather than sort through all of the disingenuous arguments presented, I want to focus on a peculiarly blatant factual misrepresentation repeated numerous times throughout the paper. It is this falsehood that the paper’s strained defense of ΛCDM (against the barrage of anomalies besetting the model) relies on:

To reduce the chance of misunderstanding I emphasize that the empirical case that the ΛCDM theory is a good approximation to reality remains compelling. (…)

… the tests have persuasively established that the ΛCDM theory is a good approximation to reality that likely requires refinement. (…)

… the ΛCDM universe has been shown to look a lot like what is observed. (…)

,,, we have a compelling case that the ΛCDM theory is a useful approximation to reality… (…)

… many well-checked tests show that the ΛCDM universe looks much (like) our universe.

Apparently the strategy is the old, repeat the lie often enough and somebody might believe it. The facts of the matter are incontrovertible though. There is no empirical evidence supporting the existence of any of the ΛCDM model’s defining features. The Cosmos we directly observe does not contain any of the following elements:

A singularity
A Big Bang event
An Inflation event
Expanding spacetime
Dark Matter
Dark Energy

Taken together, those are the defining elements of the ΛCDM model. None of them appear in the Cosmos we observe. There is not even a faint family resemblance between the ΛCDM model and the Cosmos we observe. Any claim to the contrary is simply a falsehood.

So how do cosmologists like Peebles wind up convincing themselves that their model universe looks like reality? Obviously empiricism has nothing to do with the matter. It is solely a matter of belief. Modern cosmology is simply a cult of belief. The belief system can be reduced to the following propositions:

Mathematics underlies and determines the nature of physical reality. (Mathematicism)
The assumptions of the FLRW model that underlies ΛCDM are axiomatically true and therefore the expanding universe of ΛCDM is axiomatically true.
Any physical elements that ΛCDM requires physical reality to possess in order to reconcile the model with observations must exist because the model is correct.

To be fair to Peebles here, he does admit that “... the extreme simplicity of the dark sector of the standard ΛCDM cosmology seems unlikely to be better than a crude approximation to reality…“, but that’s a pretty tepid comment considering the “dark sector” (dark matter & dark energy) of the model constitutes 95% of the model’s matter-energy content, while comprising 0% of empirical reality’s matter-energy content. It’s like saying Ptolemy’s epicycles are a crude approximation of physical reality. They are, but that is beside the point.

Both crude approximations are necessary because the underlying models (geocentrism, the expanding universe) are inaccurate representations of physical reality. The crude approximations are necessary because the foundational assumptions of both models are fundamentally wrong.

The standard model of cosmology is a crude approximation of the Cosmos in the same way that Ptolemy’s geocentric cosmology was. The Cosmos is not an “expanding universe” and the Earth is not at its center. It does not matter that cosmologists choose to believe the former but reject the latter. There is no direct empirical evidence to support their belief and the model based on it is palpably nonsensical, being entirely composed of elements (both entities and events) that do not exist in physical reality.

Science is not supposed to be the study of belief systems, it is by definition restricted to the study of physical reality. Modern cosmology as currently practiced is a belief system, not a science. Physical reality bears no resemblance to the standard model of cosmology and vice versa. ΛCDM is an abject scientific failure and it desperately needs to be relegated to the dust bin of history if cosmology is to ever become a real science rather than a playground for self-deluded mathematicists.

The Radiation Density Gradient

1 Reply

A thought experiment: Imagine a spherical blackbody the size and density of the sun. Now place that body deep in the InterGalactic Medium. In such a location a blackbody will be absorbing all of the Ambient Cosmic Electromagnetic Radiation that flows continuously through any location in the IGM. Eventually we should expect the sphere to settle into a state of equilibrium with the ACER, continuously absorbing and reemitting all the energy it receives.

This means that there must exist a Radiation Density Gradient surrounding the blackbody consisting of all the inbound and outbound radiation. By normal geometric considerations we should expect the gradient to drop off as 1/R², R being the radius.

The question is, just how much energy is that? The answer depends on the surface area of the sphere, which is easy to calculate, and the energy density of the ACER which doesn’t seem to be cleanly known, Various frequency bands have been observed to varying degrees. This recent survey of the Cosmic spectrum as a whole suggests that the aggregate nature, behavior and effect of the ACER has not been properly and fully assessed.

Given some reasonable value for the ACER density it would be possible to estimate the RDG of the sphere. With a reasonable value for the RDG a calculation could then be made, using optical considerations, of the curvature to be expected for the path of a light ray passing through the RDG, feeding that curved light back into the RDG calculation. The result could then be compared to the standard curvature predicted by General Relativity but first the additional energy directly radiated by the sun would have to be factored in. Something to think about. Somebody else will have to do the math though. That’s not my gig.

The Mathematicist’s Tale

Leave a reply

19Jun22 The following was posted as a comment to this Medium post by Eric Siegel. It has been slightly edited.

This is a good overview of the illogical mathematicism at the root of the inane Big Bang model. The Friedmann equation is indeed the headwaters of all the nonsense that currently engulfs and overwhelms any possibility of a meaningful scientific account of the Cosmos.

The Friedmann equation rests not only on the two simplifying assumptions of mathematical convenience, isotropy and homogeneity, the author cites. There was also an unstated but implicit assumption that the Cosmos could be treated as a unified, coherent, simultaneous entity, a Universe.

Further it was assumed that the field equations of General Relativity, derived in the context of the solar system, could be stretched to encompass this imaginary Universe. The results speak for themselves.

The standard model of cosmology is an incoherent, unscientific mess. It claims that once upon a time 13.8 billion years ago the entirety of the Cosmos was compressed into a volume smaller than a gnat’s ass that began expanding for an inexplicable reason, then accelerated greatly due to the fortuitous intervention of an invisible inflaton field, which set invisible spacetime expanding at just the right rate to arrive at the current state of the Universe, which we are told is 95% composed of some invisible matter and energy that has no other purpose than to make the model agree with observations; the remaining 5% of this Universe is the stuff we actually observe.

To be clear, all of the entities and events the standard model describes are not part of the Cosmos we actually observe except for that rather trivial 5% of the BB Universe. That 5% of the model is the Cosmos we observe.

Science is the study of those things that can be observed and measured. At some point in the mid 20th century theoretical physicists adopted the conceit that science was the study of mathematical models. This categorical error was compounded by treating scientific hypotheses such as “universal expansion” as axioms (true by definition). In science, all truths are provisional; nothing can be held true by definition.

Axioms belong to the mathematical domain. Math is not science and the mathematicist belief that math underlies and determines the nature of physical reality has no scientific basis. That the Cosmos is a unified, coherent and simultaneously existing entity can only be true if the Cosmos had a miraculous simultaneous origin – the Big Bang,

The problem with miracles is that they are not scientific in nature; they cannot be studied only believed in. Believing in the Big Bang and weaving a fantastical account of an imaginary Universe is a mathematical/metaphysical endeavor that has nothing to do with science or physical reality.

Imaginary Universe? That’s right, the Universe of the Big Bang has no basis in any known physics. In the physics we know, there is a finite, maximum limit to the speed of electromagnetic radiation – 3×10^8 meters per second (186,000 miles per hour). It is via electromagnetic radiation that we observe the Cosmos.

The galaxy nearest to our own is Andromeda; it is detectable by the unaided eye as a fuzzy patch in the night sky. Andromeda is @ 2.5 million light years from Earth. Everything we know about Andromeda is 2.5 million years out of date, of its current state we do not have and cannot have any direct knowledge.

At the far extent of our observational range we observe galaxies that are @10 billion light years away. We do not have and cannot have any knowledge of the current state of any of those galaxies. The same argument holds for all the other galaxies we observe.

Galaxies are the primary constituents of the Cosmos we observe. It follows, therefore, that we do not and cannot have knowledge of the Cosmos’ current state. The very idea of the Cosmos having a current state is scientifically meaningless. Mathematicists believe otherwise:

“If you want to understand the Universe, cosmologically, you just can’t do it without the Friedmann equation. With it, the cosmos is yours.“

See that’s all you need, a simple mathematical model derived 100 years ago by “solving” the field equations of General Relativity (which does not have a universal frame) for a simplistic toy model of the Cosmos (that does have a universal frame). Suddenly you can know everything about everything, even things you can’t possibly observe or measure. That’s mathematicism hard at work creating an imaginary Universe for mathematicists to believe in. The standard model of cosmology has no scientific basis; it is a nerd fantasy and it is scientifically useless.

Another Day, Another Anti-Universe Rant

I may or may not have posted this as a comment to a Quanta article. It has been modified. 25Feb2022

The belief in a wholly imaginary “universe” lies at heart of modern cosmology’s ludicrous, absurd and irrational standard model. The assumption of a universal metric with homogenous and isotropic contents underlies the FLRW equations that form the basis of all modern cosmological models.

Applying the imaginary universal metric to the field equations of General Relativity was an oxymoronic exercise that produced a ridiculous cosmological model, the Big Bang, that looks nothing like the Cosmos we actually observe. The observed Cosmos does not contain a Big Bang event, inflation, expanding spacetime, dark matter, or dark energy.

Those entities and events are part of the BB model but they are not part of empirical reality, which is to say they are not part of scientific reality. The entirety of the BB model is theoretical nonsense unhinged from the physical reality that is the only proper realm of scientific study.

Alexander Friedmann’s simplistic “homogenous and isotropic universe” assumption, made at a time when the known Cosmos consisted of our galaxy, was simply wrong. The vast Cosmos that falls within our observational range is neither homogenous nor isotropic and it makes no sense, no physical sense, to imagine that vast Cosmos constitutes a unified, coherent, and simultaneous entity.

The vast Cosmos, of which we will always have only a partial view constrained by the finite limit of light speed and the cosmological redshift, cannot be treated as a simplistic unitary entity capable of being modeled by our limited mathematical scribblings. In a very real physically meaningful way, the “Universe” of the Big Bang model doesn’t exist. It is a wholly imaginary entity.

To sustain a belief in their model of the “expanding Universe” modern cosmologists have to ignore the things that are there while believing in model-dependent imaginary things that aren’t there. Cosmology has devolved into a cult devoted to the care, maintenance, and defense of the ridiculously unscientific Big Bang model.

Modern cosmology is a mess and will remain so until the “expanding Universe” paradigm is consigned to the dustbin of history alongside Ptolemy’s geocentric model. It is time in other words to drag cosmology away from its cult-like fixation on the Big Bang and open the field to the study of cosmological models that are not dependent on the failed “expanding Universe” assumption, but are mathematically constructed to reflect the Cosmos we actually observe and measure. Humankind deserves a realistic cosmology; the dim, misbegotten fantasy we are currently saddled with doesn’t cut it.

Why The Cosmos Is Not A Universe

1 Reply

One of the fundamental assumptions underlying the standard model of cosmology, commonly known as the Big Bang, is that the Cosmos comprises a unified, coherent and simultaneous entity – a Universe. It is further assumed that this “Universe” can be mathematically approximated under that unitary assumption using a gravitational model, General Relativity, that was devised in the context of our solar system. At the time that assumption was first adopted the known scale of the Cosmos was that of the Milky Way, our home galaxy, which is orders of magnitude larger and more complex than the solar system.

Subsequently as the observed Cosmos extended out to the current 13 billion light year range, it has become clear that the Cosmos is orders of magnitude larger and more complex than our galaxy. The resulting Big Bang model has become, as a consequence, absurd in its depiction of a cosmogenesis and ludicrous in its depiction of the “current state of the “Universe“, as the model attempts to reconcile itself with the observed facts of existence.

It will be argued here that the unitary conception of the Cosmos was at its inception and is now, as illogical as it is incorrect.

I Relativity Theory

The unitary assumption was first adopted by the mathematician Alexander Friedmann a century ago as a simplification employed to solve the field equations of General Relativity. It imposed a “universal” metric or frame on the Cosmos. This was an illogical or oxymoronic exercise because a universal frame does not exist in the context of Relativity Theory. GR is a relativistic theory because it does not have a universal frame.

There is, of course, an official justification for invoking a universal frame in a relativistic context. Here it is from a recent Sabine Hossenfelder video:

In general relativity, matter, or all kinds of energy really, affect the geometry of space and time. And so, in the presence of matter the universe indeed gets a preferred direction of expansion. And you can be in rest with the universe. This state of rest is usually called the “co-moving frame”, so that’s the reference frame that moves with the universe. This doesn’t disagree with Einstein at all.

The logic here is strained to the point of meaninglessness; it is another example of the tendency of mathematicists to engage in circular reasoning. First we assume a Universe then we assert that the universal frame which follows of necessity must exist and therefore the unitary assumption is correct!

This universal frame of the BB is said to be co-moving and therefore everything is supposedly OK with Einstein (meaning General Relativity, I guess) too, despite the fact that Einstein would not have agreed with Hossenfelder’s first sentence; he did not believe that General Relativity geometrized gravity, nor did he believe in a causally interacting spacetime. The universal frame of the BB model is indeed co-moving in the sense that it is expanding universally (in the model). That doesn’t make it a non-universal frame, just an expanding one. GR does not have a universal frame, co-moving or not.

Slapping a non-relativistic frame on GR was fundamentally illogical, akin to shoving a square peg into a round hole and insisting the fit is perfect. The result though speaks for itself. The Big Bang model is ludicrous and absurd because the unitary assumption is wrong.

II The Speed of Light

The speed of light in the Cosmos has a theoretical maximum limit of approximately 3×10⁸ meters per second in inertial and near-initial conditions. The nearest star to our own is approximately 4 light years away, the nearest galaxy is 2.5 million LY away. The furthest observed galaxy is 13.4 billion LY.* This means that our current information about Proxima Centauri is 4 years out of date, for Andromeda it is 2.5 million years out of date, and for the most distant galaxy 13.4 billion years out of date.

Despite this hard limit to our information about the Cosmos, the BB model leads cosmologists to perceive themselves capable of making grandiose claims, unverifiable of course, about the current state of the Cosmos they like to call a Universe. In the BB model’s Universe it is easy to speak of the model Universe’s current state but this is just another example of the way the BB model does not accurately depict the Cosmos we observe.

In reality we cannot have and therefore, do not have, information about a wholly imaginary global condition of the Cosmos. Indeed, the Cosmos cannot contain such knowledge.

Modern cosmologists are given to believing they can have knowledge of things that have no physical meaning because they believe their mathematical model is capable of knowing unknowable things. That belief is characteristic of the deluded pseudo-philosophy known as mathematicism; it is a fundamentally unscientific conceit.

III The Cosmological Redshift

The second foundational assumption of the BB model, is that the observed redshift-distance relationship found (or at least confirmed) by the astronomer Edwin Hubble in the late 1920s was caused by some form of recessional velocity. Indeed, it is commonly stated that Hubble discovered that the Universe is expanding. It is a matter of historical record, however, that Hubble himself did not ever completely agree with that view:

To the very end of his writings he maintained this position, favouring (or at the very least keeping open) the model where no true expansion exists, and therefore that the redshift “represents a hitherto unrecognized principle of nature”.

Allan Sandage

However, for the purposes of this discussion, the specific cause of the cosmological redshift does not matter. The redshift-distance relation implies that if the Cosmos is of sufficient size there will always be galaxies sufficiently distant that they will lie beyond the observational range of any local observer. Light from those most distant sources will be extinguished by the redshift before reaching any observer beyond the redshift limited range of the source. Even in the context of the BB, it is generally acknowledged that the field of galaxies extends beyond the potentially observable range.

The extent of the Cosmos, therefore, is currently unknown and, to three dimensionally localized observers such as ourselves, inherently unknowable. A model, such as the BB, that purports to encompass the unknowable is fundamentally unscientific; it is, by its very nature, only a metaphysical construct unrelated to empirical reality.

IV The Cosmos – A Relativistic POV

Given the foregoing considerations it would seem reasonable to dismiss the unitary conception of the Cosmos underlying the Big Bang model. The question then arises, how should we think of the Cosmos?

Unlike scientists of 100 years ago when it was an open debate whether or not the nearby galaxies were a part of our galaxy, modern cosmologists have a wealth of data stretching out now to 13 billion light years. The quality and depth of that data falls off the farther out we observe however.

The Cosmos looks more or less the same in all directions, but it appears to be neither homogenous nor isotropic nor of a determinable, finite size. That is our view of the Cosmos from here on Earth; it is our point of view.

This geocentric POV is uniquely our own and determines our unique view of the Cosmos; it is a view that belongs solely to us. Observers similarly located in a galaxy 5 billion light years distant from us would see a similar but different Cosmos. Assuming similar technology, looking in a direction opposite the Milky Way the distant observers would find in their cosmological POV a vast number of galaxies that lie outside our own POV. In looking back in our direction, the distant observer would not see many of the galaxies that lie within our cosmological POV.

It is only in this sense of our geocentric POV that we can speak of our universe. The contents of our universe do not comprise a physically unified, coherent and simultaneously existing physical entity. The contents of our universe in their entirety are unified only by our locally-based observations of those contents.

The individual galactic components of our universe each lie at the center of their own local POV universe. Nearby galaxies would have POV universes that have a large overlap with our own. The universes of the most distant observable galaxies would overlap less than half of our universe. Those observers most distant and in opposite directions in our universe would not exist in each others POV.

So what then can we say of the Cosmos? Essentially it is a human conceptual aggregation of all the non-simultaneously reviewable matter-energy systems we call galaxies. The field of galaxies extends omni-directionally beyond the range of observation for any given three dimensionally localized observer and the Cosmos is therefore neither simultaneously accessible nor knowable. The Cosmos does not have a universal frame or a universal clock ticking. As for all 3D observers, the Cosmos tails away from us into a fog of mystery, uncontained by space, time, or the human imagination. We are of the Cosmos but can not know it in totality because it does not exist on those terms.

To those who might find this cosmological POV existentially unsettling it can only be said that human philosophical musings are irrelevant to physical reality; the Cosmos contains us, we do not contain the Cosmos. This is what the Cosmos looks like when the theoretical blinders of the Big Bang model are removed and we adopt the scientific method of studying the things observed in the context of the knowledge of empirical reality that has already been painstakingly bootstrapped over the centuries by following just that method.

___________________________________________________

* In the funhouse mirror of the Big Bang belief system, this 13.4 GLY distance isn’t really a distance, it’s the time/distance the light traveled to reach us. At the time it was emitted according to the BB model the galaxy was only 2.6 GLY distant but is “now” 32 GLY away. This “now“, of course, implies a “universal simultaneity” which Relativity Theory prohibits. In the non-expanding Cosmos we actually inhabit, the 13.4 GLY is where GN-z11 was when the light was emitted (if our understanding of the redshift-distance relation holds at that scale.) Where it is “now” is not a scientifically meaningful question because it is not an observable and there is. in the context of GR, no scientific meaning to the concept of a “now” that encompasses ourselves and such a widely separated object.

Two Big Lies

This fundamental idea — that matter and energy tells spacetime how to curve, and that curved spacetime, in turn, tells matter and energy how to move — represented a revolutionary new view of the universe. Put forth in 1915 by Einstein and validated four years later during a total solar eclipse — when the bending of starlight coming from light sources behind the sun agreed with Einstein’s predictions and not Newton’s — general relativity has passed every observational and experimental test we have ever concocted.
How to understand Einstein’s equation for General Relativity

Sooner or later it seems Ethan Siegel will trot out every disingenuous argument employed by the Big Bang cult in support of its peculiarly unscientific belief system. Two big lies about General Relativity popular among the faithful are succinctly presented in the above quote. The first is that Einstein “put forth” the idea of that GR reduced gravity to the geometrization of a substantival spacetime.

Einstein opposed that view throughout the years subsequent to GR’s introduction, whenever it was proposed. That is a matter of historical record. The formulation that Siegel presents here is a paraphrasing of John A. Wheeler’s well known assertion. That assertion directly contradicts Einstein’s clearly and repeatedly stated position on the matter.

The second big lie is that GR “has passed every observational and experimental test…“. That is true only of tests performed on the scale of the solar system. GR does not pass tests on galactic and cosmological scales without the ad hoc addition of dark matter and dark energy. The existence of neither of those hypothetical entities is supported by direct empirical evidence; the only support they can realistically be said to have is that they reconcile GR with observations. Siegel knows this, he just chooses not to mention it. That is what is known as a lie of omission:

Lying by omission, also known as a continuing misrepresentation or quote mining, occurs when an important fact is left out in order to foster a misconception… An omission is when a person tells most of the truth, but leaves out a few key facts that therefore, completely obscures the truth.

Adventures in Theoretical Physics II – Fun with General Relativity

Leave a reply

Well here’s a cute little video that manages to do a good job of conveying just how daft and detached from reality theoretical physics has gotten over the last century:

The first 11 minutes or so are effectively a sales pitch for one of the structural elements of the Big Bang Model – Spacetime. The deal is, you’re supposed to believe that the force of gravity is not really there – nothing is holding you to the surface of the earth, rather the earth is accelerating upward and pushing against you.

And the reason this is happening is that you are not following a curved path in –Spacetime, because according to the video you are being knocked off of that curved path by the earth that is accelerating upwards and you are in the way and that’s gravity, tada! How do we know this? Well that’s obvious, it’s in the math and the math tells reality what’s going on and if reality doesn’t like it, that’s too bad. So don’t go trusting your lying eyes, alright.

In addition to Spacetime, this fairy tale is predicated on a ridiculous over-extension of the Principle of Equivalence that Einstein used in developing Special Relativity. Einstein was very clear that the POE applied only under the severely constrained circumstances of a thought experiment. His main purpose seems to have been to provide a physical interpretation for the observed equivalency between gravitational and inertial masses. Einstein presented the POE as informing his ideas about gravity.

The video ignores Einstein’s constraints and pretends the POE is fundamental to General Relativity, so it winds up insisting that things that are obviously not true in physical reality, are, nonetheless, true simply because the math can be framed that way – your lying eyes be damned.

We are told that a man falling off a roof is in the exact same situation as an observer in a non-accelerating rocket ship far from any gravitating body. This claim is made even though it is obviously not true; the falling man will be injured, if not killed, when he hits the ground, whereas no such fate will befall the observer in the rocket ship.

So the idea is, until the falling man meets his unfortunate fate, the situation is the same and therefore both situations are the same, the different outcomes not withstanding – because the math is the same. Observers free falling in orbit won’t be able to tell they’re not in an inertial frame – unless they look out the window, so that’s just like being in an inertial frame too. Right, of course.

In a similar vein, the video insists that an observer in a rocket accelerating at 9.8 m/s^2 will not be able to tell the difference between that situation and standing on the surface of the earth. The presenter fails to mention however, that only holds true as long as the observer doesn’t observe out the window, which will alert the observer that the rocket and therefore the observer are not at rest on the surface of a large gravitating body and therefore the situation is not comparable to standing at rest on the surface of the earth. Also, if any observer steps off the rocket, they will be left behind as the rocket accelerates away. But nevertheless, it’s all the same – as long as no one looks out the window, and maybe you remember that the earth is actually accelerating upwards under your feet, like the floor of the rocket. Sure, of course.

For the sake of introducing some sanity in this matter, here is Einstein on the POE. Note that the second paragraph completely contradicts the claims made in the video implying the equivalence of all inertial and non-inertial frames.

We must note carefully that the possibility of this mode of interpretation rests on the
fundamental property of the gravitational field of giving all bodies the same acceleration, or, what comes to the same thing, on the law of the equality of inertial and gravitational mass…
Now we might easily suppose that the existence of a gravitational field is always only an apparent one. We might also think that, regardless of the kind of gravitational field which may be present, we could always choose another reference-body such that no gravitational field exists with reference to it. This is by no means true for all gravitational fields, but only for those of quite special form. It is, for instance, impossible to choose a body of reference such that, as judged from it, the gravitational field of the earth (in its entirety) vanishes.
RELATIVITY THE SPECIAL AND GENERAL THEORIES, ALBERT EINSTEIN, authorized translation by Robert W. Lawson, original version 1916, translated 1920, appendices 3 and 4 added 1920, appendix 5 added to English translation 1954

It is clear from this statement that the POE of Einstein’s thought experiment is the Galilean version, commonly referred to nowadays as the “Weak” POE. The so-called “Einsteinian” and “Strong” POEs of modern cosmology are post-Einstein formulations attributed initially to Robert Dicke, though there were doubtless others who perpetrated and embellished this nonsense. Neither extension of the POE has anything to do with the foundations of Einstein’s Relativity Theory. It is those mid-20th century extensions that are misleadingly presented in the video as fundamental features of General Relativity.

The POE, in its current, extended usage, is mostly just a conjecture of mathematical convenience, allowing theorists to use Special Relativity math instead of the more difficult General Relativity formulations. It also results in a theoretical claim that the speed of light in a vacuum is a universal constant. That claim contradicts both GR which predicts that the speed of light varies with position in a gravitational field and observations which confirm that prediction.

This unwarranted belief that the speed of light is a universal constant has also produced a cottage industry of theorists expounding a theory of undetected structures called Black Holes with the physically absurd properties of an event horizon and a singularity. No such structures exist. The relativistic slowing of light in a gravitational field precludes their existence. It does not preclude the existence of massive high-density objects.

Ok, let’s grant that this video presentation is of dubious scientific quality and does not, perhaps, represent the consensus view of the scientific community, particularly with regard to the so-called Principle of Equivalence, although if not the consensus, the Strong POE certainly commands significant support by a majority of theoretical cosmologists . The usual suspects will whine, of course, that pop-science presentations like this video cannot be trusted.

That complaint is also lodged against anything written for a general audience, even when the author is a fully accredited scientist with a relevant FAS (full alphabet soup) after their name. If it’s written so non-experts can understand it, then it is, on some level, wrong.

The reason for this situation is straightforward: much of what theoretical physicists believe cannot be translated into clear, logical, statements of scientific fact. What you get instead is confident handwaving consisting of metaphysical assertions that have no factual basis in empirical reality and a lot of math. According to theorists this is because theoretical physics can only be properly understood by those steeped in years of study of the underlying mathematical esoterica that informs only the truly knowledgeable. To which the only proper retort is: math is not physics and if your math cannot be translated into empirically verifiable physical terms – then your math is inadequate to the task of being a proper scientific model of physical reality.

The modern POE is just a conjecture of mathematical convenience, nothing more. Nonetheless, this modern POE permeates and perverts the scientific literature. Here is an Encyclopedia of Britannica entry for the POE:

In the Newtonian form it asserts, in effect, that, within a windowless laboratory freely falling in a uniform gravitational field, experimenters would be unaware that the laboratory is in a state of nonuniform motion. All dynamical experiments yield the same results as obtained in an inertial state of uniform motion unaffected by gravity. This was confirmed to a high degree of precision by an experiment conducted by the Hungarian physicist Roland Eötvös. In Einstein’s version, the principle asserts that in free-fall the effect of gravity is totally abolished in all possible experiments and general relativity reduces to special relativity, as in the inertial state.
Britannica, The Editors of Encyclopaedia. “Equivalence principle”. Encyclopedia Britannica, 31 Mar. 2019, https://www.britannica.com/science/equivalence-principle. Accessed 6 June 2021.

It should be noted that, according to the encyclopedia’s referenced article on Roland Eötvös, his experiment “… resulted in proof that inertial mass and gravitational mass are equivalent…“, which is to say, that it demonstrated the Weak POE only. It is also clear, that the authors of this entry are confused about the distinctions between the three POEs. But what of that; it’s only an encyclopedia trying to make sense of the nonsensical world of the modern theoretical physicist and modern theoretical physics is an unscientific mess.

Adventures in Theoretical Physics I – Entropy

Leave a reply

Updated 3Jun21

Entropy is one of those slippery concepts floating around in theoretical physics that defies easy explication. The following quote is from a small subsection of an extensive Wikipedia entry on entropy:

The following is a list of additional definitions of entropy from a collection of textbooks:
-a measure of energy dispersal at a specific temperature.
-a measure of disorder in the universe or of the availability of the energy in a system to do work.
-a measure of a system’s thermal energy per unit temperature that is unavailable for doing useful work.
In Boltzmann’s definition, entropy is a measure of the number of possible microscopic states (or microstates) of a system in thermodynamic equilibrium. Consistent with the Boltzmann definition, the second law of thermodynamics needs to be re-worded as such that entropy increases over time, though the underlying principle remains the same.

Note that this is a “list of additional definitions”, there are seemingly innumerable others peppered throughout the article. It would be a hard to caricature the overall impression of incoherence, oozing like quicksand and sucking under any rational attempt to say concisely what, exactly, entropy is, beyond the usual handwaving about a vaguely specified measure of disorder.

The first sentence of the Wiki article states unequivocally that “Entropy is… a measurable physical property…”. That statement is false. In section 7.8 it is made clear that entropy cannot be measured directly as a property. Rather, discrete energy transfers are dropped into an equation that ostensibly “describes how entropy changes $dS$ when a small amount of energy $dQ$ is introduced into the system at a certain temperature $T$ .” The only measurements made are of energy and temperature. Entropy is a made-up mathematical concoction; It is not a real property of physical reality.

The reader will also be pleased to note that the same article informs us that “In 1865, Clausius named the concept of “the differential of a quantity which depends on the configuration of the system,” entropy… “.

The real problem with the concept of entropy is not that it may be useful in doing some thermodynamic calculations. Clearly, it is of some mathematical value? What it does not have is any clear explanatory power or physical meaning, and well, math just isn’t physics. Nonetheless, entropy has been elevated to a universal, physical law – the Second Law of Thermodynamics, where the situation doesn’t get any less opaque. In fact the opacity doesn’t get any more opaque than this gem:

Nevertheless, this principle of Planck is not actually Planck’s preferred statement of the second law, which is quoted above, in a previous sub-section of the present section of this present article, and relies on the concept of entropy.
Section 2.9 of the 2nd Law wiki entry above

Here is Planck’s quote from “…a previous sub-section of the present section of this present article…”:

Every process occurring in nature proceeds in the sense in which the sum of the entropies of all bodies taking part in the process is increased. In the limit, i.e. for reversible processes, the sum of the entropies remains unchanged.

Of course, the only question that remains then is, what exactly is entropy?

The final word on the nature of entropy should be this comment by John von Neumann which appears in a sidebar of this section, wherein he advises Claude Shannon to call his information uncertainty concept entropy because “… In the second place, and more important, nobody knows what entropy really is, so in a debate you will always have the advantage.” Can’t argue with that logic. It appears that the definition of entropy is entropic. It is getting ever more disordered with the passage of time.

So what’s the problem? This is after all, a relatively trivial matter compared to the Grand Delusions of Theoretical Physics, like Dark Matter, Dark Energy, Quarks & etc. Or is it? Well, actually the Entropy Paradigm represents a major blind spot in fundamental physics. Theoretical physics has this misbegotten, laboratory based idea that all ordered systems are in some sense, “running down” or losing the ability to do work, or becoming more disordered or, or… something, called Entropy.

Entropy is all downhill, all the time. In the context of a designed laboratory experiment, the original, closed-system condition is some prearranged, ordered-state, that is allowed to “run down” or “become disordered” or whatever, over time and that, more or less is Entropy! Fine so far, but when you make Entropy a universal law – The Second Law of Thermodynamics, all is lost, or more exactly half of reality is lost.

Why? Because there are no closed systems outside the laboratory. What you get when you ignore that fact is this kind of bloated nonsense:

The law that entropy always increases holds, I think, the supreme position among the laws of Nature. If someone points out to you that your pet theory of the universe is in disagreement with Maxwell’s equations – then so much the worse for Maxwell’s equations. If it is found to be contradicted by observation – well, these experimentalists do bungle things sometimes. But if your theory is found to be against the second law of thermodynamics I can give you no hope; there is nothing for it but to collapse in deepest humiliation.
Sir Arthur Stanley Eddington, The Nature of the Physical World (1927)

Entropy is correct, if all it boils down to is, ordered, closed, systems will become disordered. But entropy doesn’t tell you how the systems came to be ordered in the first place. If you extrapolate from a closed-system experiment, a Universal Law that says, or implies, that all systems rundown, but you have no theory of how those systems came to be ordered in the first place, you have exactly half a picture of reality – because over here in the real world, ordered systems do arise from disorder.

It’s hard to do good physics if you have this half-blind view of reality. You start babbling about the Arrow of Time, the heat death of the Universe, not to mention whatever this is. You may have to invoke an unobservable Creation Miracle like the Big Bang to get the ball rolling.

Babble Update (3Jun21)

“If you want your clock to be more accurate, you’ve got to pay for it,” study co-author Natalia Ares, a physicist at the University of Oxford, told Live Science. “Every time we measure time, we are increasing the universe’s entropy.”
Livescience.com

Meanwhile, physical reality doesn’t work like that. Physical reality is locally cyclic – like life itself. There is, for instance, a considerable body of observational evidence suggesting that galaxies reproduce themselves. That body of evidence has been dismissed with spurious statistical arguments, and the well-established astronomer who made them, Halton Arp, was denied telescope time to continue making those observations. No one has since been permitted to pursue that line of observational research.

Meanwhile, there is also no comparable body of observational evidence for the Big Bang supported model of galaxy formation, via accretion, from a primordial, post-BB cloud. Like the rest of the Big Bang’s defining features, galaxy formation by accretion is not an observed phenomenon in the Cosmos.

So, an over-generalization (to the point of incoherence), of some simplistic closed-system laboratory experiments done in the 18th and 19th centuries, has come to aid and abet, the absurd Big Bang model of the Cosmos. Modern theoretical physics is an incoherent, unscientific mess.

Starts With a Bang, Ends With Nonsense

Ethan Siegel’s columns for Forbes magazine are tour de forces of the illogical circular reasoning that passes for scientific discourse in the modern theoretical physics community. They are best avoided out of respect for the good name of science. It is, however, sometimes instructive, not to mention eye-opening, to slog through one, in order to appreciate just how self-deluded the pseudo-science known as modern cosmology has become.

Case in point: this article from Dec 22, 2020. Therein, Siegel is at great pains to demonstrate that dark matter and dark energy are the only scientific way of accounting for observed cosmological phenomena in the context of the Standard Model of Cosmology, commonly known as the Big Bang model. This is true of course, the BB model can only account for cosmological observations if it is allowed to invoke the existence dark matter and dark energy – so therefore dark matter and dark energy must exist despite the absence of any empirical evidence for their existence. Reasoning can’t get any more circular than that.

In some of Siegel’s arguments there is almost no logical argument at all, just a recitation of certain facts followed by an assertion unsupported by the facts presented, that those factual observations were predictions rather than post-dictions of the model (emphasis added):

What’s remarkable is that, because the laws of physics that govern particles (and nuclear fusion) are so well-understood, we can compute exactly — assuming the Universe was once hotter, denser, and expanded and cooled from that state — what the different ratios of these different light elements ought to be. We’ve even studied the reactions in the lab directly, and things behave precisely as our theory predicts. The only factor we vary is the photon-to-baryon ratio, which tells us how many cosmic photons (particles of light) there are for every proton or neutron (the baryons) in our Universe.
We’ve now measured it all. Satellites like COBE, WMAP, and Planck have measured how many photons there are in the Universe: 411 per cubic centimeter of space. Intervening clouds of gas that appear between us and a distant light source, like a luminous galaxy or quasar, will absorb a fraction of the light as it travels through the Universe, teaching us the abundances of these elements and isotopes directly. When we add it all up, only ~5% of the total energy in the Universe can be normal matter: no more and no less.

What a mess! The central assumption (emphasized above) is simply the BB model, which is itself based on two foundational assumptions:

The cosmos is a unitary, coherent, simultaneous entity – a “Universe”.
The cosmological redshift is caused by some form of recessional velocity.

Neither of those assumptions has any empirical basis and both date to the early 20th century when the scale of the cosmos was barely grasped. They are however, sacrosanct among cosmologists. Those foundational assumptions are, by some common but unstated agreement, true by definition in the cosmological community. They are more than just assumptions, they are beliefs, and they are almost certainly wrong. But, what of that… Assuming our assumptions are correct we can use math to massage our model into agreement with observations – just like good old Ptolemy did way back around the dawn of the previous Dark Ages.

More recently Siegel has posted a similarly obtuse argument concerning the supposed successes of the Big Bang model and its unchallengeable status. It features the same kind of circular reasoning as above: Our model is correct as long as our assumptions and postulates are correct, therefore the things we assume and postulate are correct, because the model is correct. The result of this transparently illogical syllogism, which underlies all of the author’s triumphalist claims for the Big Bang model, is the nonsensical narrative that winds from inexplicable Big Bang to the now 95% invisible “Universe”.

The reason there are no significant challenges to the Big Bang orthodoxy from within the scientific community is that the community members have been trained to accept the 100 year old premises of the model. So, again, the author is correct to this extent: if you accept the model’s premises you are going to wind up with some ludicrous depiction of the Cosmos like LCDM. However, the simplistic assumptions of 100 years ago have proven a disastrous foundation for modern cosmology. The model depicts an inane, unscientific, “Universe” that does not at all resemble, in its defining features, the Cosmos we actually observe.

In the Cosmos we observe there is no Big Bang event, no inflation, no expanding spacetime, no dark matter, no dark energy. All of those things are essential elements of LCDM . None of those things are present in the Cosmos we observe. Physical reality does not look like the LCDM “Universe”. People like the author, who, nonetheless, believe the absurd LCDM story, do so because they are functionally, mathematicists.

Mathematicism is an ancient, half-baked philosophy whose proponents believe that mathematics underlies and determines the nature of physical reality. So, dark matter (& etc.) cannot be empirically demonstrated to exist? That is of no concern to a mathematicist; it all has to be there because a peculiar model (LCDM) requires it in order to reconcile itself with observations, and therefore dark matter (& etc.) have to exist. Pay no attention to the testimony of your lyin’ eyes (and telescopes)!

Mathematicism is junk philosophy. It is not science. How we got to this state of affairs is going to provide plenty of work for future historians of science. For now though, there is much to do just to pry the cold, dead hands of mathematicism from the throat of theoretical physics (which is now barely alive in any scientific sense).

Science rests on observation (detection) and measurement, not the febrile imaginings of reality-challenged, nerd-mathematicists with a cult-model to defend. What passes for science among the theoretical physics community of the academy these days is not science in any meaningful sense. The Big Bang model is Exhibit A for that proposition.

(Parts of this post were taken from a comment I made on Siegel’s Medium article.)

So, an interesting and even-handed account of the recent acknowledgement by the US government of ongoing investigations into UFO phenomena contains this whopper:

Interstellar travel by living beings still seems like a wildly remote possibility, but physicists have known since the early nineteen-nineties that faster-than-light travel is possible in theory, and new research has brought this marginally closer to being achievable in practice.

This is not an accurate scientific assessment of the possibility of faster-than-light travel. What it appears to be referring to is the mathematicist fantasy of an Alcubierre warp-drive. You can find a succinct presentation of this “theory” here. It is a short and not technically difficult presentation which seems to reach a straightforward conclusion:

At present, such a thing just doesn’t seem to be entirely within the realm of possibility. And attempts to prove otherwise remain unsuccessful or inconclusive.

Things would have been fine if they left it at that but the nerd community, having had their minds warped by too many repeated viewings of Star Wars-Trek fantasy-fiction- movies, had to add a more hopeful note:

But as history has taught us, what is considered to be impossible changes over time. Someday, who knows what we might be able to accomplish?

Unfortunately history has also taught us that the human imagination is not a reliable guide to the nature of physical reality. The Alcubierre drive rests on the scientifically baseless presumption that spacetime is a causally interacting element of physical reality. There is no empirical evidence for such a presumption.

There is, however, a significant contingent of Academy Certified Scientists who believe in the existence of a physical spacetime. This belief is entirely based on the assumption, by the mid-20th century neo-Relativists (Misner, Thorne, Wheeler, et al), that such a spacetime exists. However, real science cannot be based on what MTW (or you or I) believe. Real science rests on empirical evidence, not on, in this case, the spurious reification of relational concepts.

Like Star Wars itself, the Alcubierre drive is a pseudo-scientific fantasy that amuses and confuses a certain reality-challenged subset of humanity, many of whom, unfortunately, are puking up this indigestible, hairball of irrationality in the halls of the Scientific Academy. The New Yorker is not to blame for this mess, but thoughtlessly repeating such unscientific nonsense, as if it had a scientific basis, is not helpful.

The Unprincipled Principle & The Persistence of Mistakes

Over at Triton Station, Stacy McGaugh has a series of posts on the recent, and ongoing, successful predictions of MOND at the galactic scale, beginning with the December 31, 2020 post, 25 Years A Heretic, which provides an excellent historical overview of the situation. It is thankfully, solidly couched in empirical observations.

The last two posts in the Comments section of the linked post are by Apass and Phillip Helbig. I had intended to reply to them in a timely fashion but by the time I got around to it the Comment section was closed. Following are the replies I intended to post:

@Apass,

… through what mechanism would this new disk model give rise to the EFE felt by a satellite galaxy isolated by tens of thousands of light years where you cannot invoke anymore viscosity-like effects?

Given that the mechanism through which gravity causes its effects is generally unknown, that’s an odd question. If a theoretical model of disk dynamics limning the mass distribution replicated MOND’s success in describing the rotational curves, I would be surprised if it didn’t also account for the EFE. After all, satellite galaxies are not, by definition, gravitationally isolated from their host galaxy.

The fact that DM didn’t predict the EFE is probably a function of the fact that DM doesn’t successfully predict anything except itself. It is always deployed, as a patch to a failure of an implementation, on significantly larger scales, of the standard gravitational model of the solar system. If the EFE holds up, which I expect it will, there will likely be a concerted effort to post-dict it with DM. This would present an existential problem to the SMoC proponents however, as the EFE overturns the unprincipled Strong Equivalence Principle.

The SEP is not an expression of empirical fact, the way the weak principle of equivalence is (the equality of inertial and gravitational mass); it is little more than an idle conjecture of mathematical convenience, adopted mid-twentieth century, right at the onset of the post-Einsteinian revision of General Relativity.

The SEP is not foundational to the SMoC, but it is well integrated into the mindset of its practitioners and has consequences for the theoretical “study” of theoretical entities like black holes and multibody systems like galaxy clusters. Dispensing with the SEP would, for one thing, mean that cosmologists could now stop believing, contrary to the empirical evidence and GR prediction, that the speed of light in a vacuum is a universal constant.

@Phillip Helbig

Note that in the standard cosmological model, only 1920s cosmology is used. Despite the huge amount of high-quality data now available, classical cosmology needs nothing beyond what was known about relativistic cosmology in the 1920s.

Well yes, and that’s why we need a 21st century cosmology with, shall we say, more realistic underpinnings. I really don’t understand why anyone would think clinging to the naive and dubious assumptions of 100 years ago is a scientifically sound approach, especially given the manifest failures of the current model. I understand that the SMoC is graded on the curve, with negative empirical results deeply discounted in favor of theoretical requirements – but still, the model’s defining structural elements all lie totally in the realm of the empirically undetected.

The fact that there appears to be absolutely no interest in revisiting the standard model’s foundational assumptions, even as an exercise in intellectual curiosity, says nothing good about the socio-economic incentives of the modern scientific academy. The Big Bang model is the best possible you say? I would agree, but only with the caveat that it is only so in the context of the model’s essentially pre-modern assumptions. As soon as those are jettisoned, the big bang creation myth will almost certainly become nothing more than a historical curiosity.

Nobel Prize in Physics Awarded to 3 Scientists for Work on Fairy Tale

It’s sadly, depressingly true. Some mathematicist nonsense that attends modern cosmological theory has been awarded science’s grandest prize:

This award has been given to mathematical work on a mathematical theory that has nothing to do with actual physics. Black holes, the ostensible subject matter of the work are fictitious entities that only arise in a mathematical models (such as Schwarzschild solution to the field equations of General Relativity) that ignore one of the fundamental consequences of General Relativity – the speed of light varies with position in a gravitational well.

Specifically, the steeper the gravitational well, the slower the speed of light. It follows directly from this, an observed fact, that gravitational collapse is a self-limiting event. In the Schwarzschild and similar solutions, the speed of light is held constant and results in a theoretical collapsed state (a black hole) that is physically nonsensical, containing as it does a singularity (a mass of zero-volume and therefore infinite density).

Modern theoretical cosmology is a mess, in which Einstein’s General Relativity has been dumbed-down in service of mathematical convenience. The result has been dumb-downed, mathematical models (the Big Bang, black holes), that present physically nonsensical accounts of observed reality. These models do not remotely resemble the physical reality we can actually observe and measure. They are mathematical fairy tales.

The Nobel Prize in Physics was just awarded for work on a dumbed-down mathematical model that has nothing to do with real physics.
