Dirac's Way to Quantum Gravity

While current candidates for QG like string theory and LQG are probably not the solution to the problem, and I do think a theory of everything should ultimately be quantitative, I think there is a very big issue with comparing this kind of "numerology" to what Maxwell found. The difference lies with _intensive_ versus _extensive_ properties of the universe. The properties that Maxwell related are all intensive properties (electric constant, magnetic constant, speed of light/causality) which do not correspond to any particular structure and are thus true "universal" properties of the universe that are likely directly birthed from a theory of everything (or are true free parameters birthed at the creation of the universe). The ratios that are present in this video, however, all incorporate extensive properties like the mass of the proton, radius of the proton, mass of the observable universe, and radius of the observable universe. There are two major issues with this: 1. When you allow yourself to consider extensive properties as fundamental constants, the adjustable degrees of freedom that you can use to arbitrarily make approximate equations dramatically increases. This is especially the case for properties of structures (ie protons and the entire universe) versus fundamental particles which there are relatively few of. Some questions: Why the proton specifically? Why not the neutron? Why use the rms charge radius of the proton and not another definition of its radius (since a proton is actually boundary-less)? Why not the electron? Why not any other particle? Why not some other structure of quarks, like mesons, of which there are hundreds (protons being the most common charged baryon due to them being the most stable should not make them uber-special such that their properties would relate to the ratio of the fundamental forces)? Why the ratio of the electric to the gravitational force, and not the strong or weak forces? The strong force very likely has much more influence on the proton charge radius than gravity does. Why the size/matter of the observable universe, and not the minimum size of the known universe which is at least 500 times larger than the observable one based on large-scale cosmology? This doesn't even touch the issue of using other math constants (like pi or the golden ratio or e or any of the many, many constants) to try and make the equations work as experiments get more accurate. Why pi/2, and not pi/4, or 2*pi, or pi^2, or pi^2/2, or the golden ratio, or 8, or 8*e^2, and so on... It is very easy to get agreement to 6, 8, 10 decimal places when you have so many degrees of freedom that you don't need to have real justification for. 2. The deeper issue is that the extensive properties of structures like protons and the universe likely arise from an extremely complicated mess of different aspects of physics coming together to create an essentially arbitrary extensive property with little direct, simple relation to intensive fundamental constants. The radius (and mass) of the proton, for example, likely arises from a complicated mess of primarily strong interactions. The proton is known to have a mess of quarks and virtual gluons that interact in extremely complicated ways. The probability that the radius (or mass which would also involve the Higgs and other effects) that results from this mess of interactions relates cleanly to other fundamental constants is quite low (even if you ignore the first point about many degrees of freedom). This issue is even greater for something like the size of the observable universe and its matter content. The density of baryon matter in the universe arises from several different physical aspects of the early universe (like the varying expansion rate, the ratio of matter to anti-matter, the stability of certain arrangements of quarks, ect.) coalescing into an effectively arbitrary number for density. If this density were to be predicted from a theory of everything using only fundamental constants, it would likely involve, at a minimum, a dizzying array of integrals and other expensive computations, not some simple "nice" formula in terms of fundamental constants. I have no problem with physicists playing around with constants and equations to see if something interesting comes up. I also don't have a problem with _some_ people trying their best to investigate the supposed leads that this numerology gives. However, to claim that these relations are exact or meaningful, or to claim that this way of trying to develop a theory of quantum gravity is the most likely to succeed, is completely unjustified IMO. TL;DR If your physical relation takes advantage of many degrees of freedom to adjust the numbers, and you don't have a fleshed-out physical justification for your relation, its probably shit.

[@armagetronfasttrack9808]

@@AlicanErenKuzu You misunderstand the definition of quantitative. Quantitative in this context just means that the theory predicts a numeric value for physical constants (and other phenomena). An example of a quantitative theory would be the prediction of the number that is the fine structure constant, as opposed to a qualitative theory that would merely say that there _is_ a fine structure constant that plays a certain role in the physics.

[@JoeTaber]

I agree with this analysis. Ideally, if one would want a new numerology-based theory like this to be taken seriously, one would state all the possible degrees of freedom that you've allowed yourself, their justifications (if any) and honestly analyze: Given a random theory taken from the space of possible theories you've constructed by your choice of degrees of freedom, how likely would that random theory be your theory?

@neil u They are basically say that there is an ether medium upon which the speed of light is based. This is the same way the speed of sound is an energy wave in air. Dirac basically states that there is an ether medium, AKA a sea of photons. en.wikipedia.org/wiki/Dirac_sea It was the basic premise of Tesla and Steinmetz, that electrons are condensers of this medium, and condense a quantized amount of these particles, or dielectric out of the ether medium. A radio signal is the condensing and rarefying of the dielectric. In fact when you follow this model, that charged particles are condensers of the ether medium, all of the mainstream paradoxes disappear. It appears that energy is created by momentum of these particles, by condensing and rarefying this medium, like an air conditioner uses a fluid medium to transfer energy by compression and rarefaction of a freon, use particle momentum to transfer energy. In fact Ron Hatch and GPS prove that there is a medium. The speed of light varies with the density of this medium. This is the Lorentz ether gauge theory. www.tuks.nl/pdf/Reference_Material/Ronald_Hatch/Hatch-Relativity_and_GPS-II_1995.pdfwiki.naturalphilosophy.org/index.php?title=Ronald_R_Hatch Hatch has a new version of gravity that is based upon the ether medium density, which dictates the energy level, and the speed of light varies with the flux density, just as redshift, refractive index, clock speed, and back - emf do. www.deere.com/assets/pdfs/navcom/Featured%20Articles/inside_gnss_janfeb08_humaneng_ron_hatch.pdf Here is Hatch on Pound- Rebka. www.naturalphilosophy.org/pdf/abstracts/abstracts_538.pdf Gravity is basically due to the ether medium density condensed within masses, and gravity then is magnetic, or ether medium pressure mediation of the medium condensed within matter. Planck's constant is the only true constant in the Universe.

You haven't read Dirac's papers on quantum gravity, from the early 1950s. His "large numbers hypothesis" is now called "The naturalness problem" and it is unsolved. There is no way to more way calculate the fine-structure constant from first principles than there is to work out the number of stars in the milky-way from first principles, they are both determined by historical accident. This is because the fine-structure constant runs with energy, and at high energy, it depends on how exactly gravity and the other forces are separated.

I studied some of Dirac's personal manuscripts and yes, he did think about some very interesting “coincidences", but let us think about it: the radius of the universe is a consequence of the passage of time, related both to its expansion and to the fact that light hasn't had enough time to reach us from a more distanced point. Since the proton's radius seems to be constant, what does this tell us? That dinosaur-Dirac and future-alien-Dirac wouldn't find this to be a remarkable coincidence at all. It is probably just numerology.

[@TheMachian]

Which papers did you study? Take the 1937 nature paper or the 1938 PRS paper, and you'll find the answers. The intriguing idea is that those numbers coincide also in what you call teh dinosaur and the alien case.

Einstein's "variable speed of light" isn't a variable speed of light theory, it is the truncation of GR to g_00 only. This means clocks tick at different rates at different positions. You shouldn't interpret it as a 'variable speed of light' because the local speed of light as measured by any experiment would still be roughly constant in the proper theory. I say "roughly", because you are ignoring the small effects of the off-diagonal parts of the metric tensor. The proper solution includes the whole metric tensor, Einstein realized that the scalar theory wasn't complete very quickly, he never expected it to be more than a heuristic guide to a full theory. A full scalar theory is Nordstrom gravity, which has no light deflection, unlike the original Einstein 1907 theory you reference, which has half the correct deflection. The full deflection is due to the space-space components of the metric, which contribute equal amount of deflection for a particle moving at the speed of light, and do not contribute at all to a particle moving slowly, for which Einstein's 1907 theory is sufficiently accurate.

Machs Principle ist only another interpretation of the fact, that the radius of the universe is equal to the Schwarzschild radius of a black hole with the mass of the universe (R=2MG/c²). Also the density (mass devided by 4/3 pi R³) of a black hole is simply derived from its Schwarzschild radius because itself is proportional to its mass: M=c²R/2G, D=3M/4piR³=3c²/8GMpiR². This leads to the observed number of protons (ca. 2 / m³) in the universe.

[@glynnec2008]

The problem with the Large Number Hypothesis is that the known universe is two or three orders of magnitude larger than it was in Dirac's day. So one of his dimensionless numbers has changed so much that it no longer matches the other in any spooky way. Also the proton is not an elementary particle like an electron or a quark, so why should we care about its radius or its mass? The number of particles used by Dirac is also suspect. We know about lots more particles today, e.g. neutrinos. So that number is also not spooky anymore. This whole approach to physics seems more like astrology or numerology -- or as the quote on one of the slides puts it: "a remarkable coincidence." But since the numbers no longer *coincide* you can't even call it that.

[@altrag]

TLDR: All the hard work done in the past 40 years is wrong because we can't generate the energy needed to test it, but some random coincidences people noticed almost a century ago is promising, even though none of it has been formulated into an actual theory, and would likely be even less testable if it were." ... I mean its fine to get inspiration from coincidences -- lots of (good) science has come from people noticing odd things and pursuing them. But you've got to actually do that "pursuing them" step before coincidences can be considered actually useful. The fact that I have 5 fingers on my hand and a starfish has 5 arms doesn't imply that starfish are in any way related to human hands by itself, even though its a coincidence.

[@TheMachian]

Well I'd say pretty good evidence for evolution if many animals have 5 fingers... . For the rest, you are right. Feel free to develop a model based on Dirac. However, it's also useful to weed out the crap. Today, there is a lot....

[@altrag]

@@TheMachian Yep there's definitely a lot of crap, but figuring out which is the crap and which is plausible is less certain. We do know one thing though, "testable" can't be our determining factor anymore. The Standard Model and General Relativity both stand up exceedingly well in experiment to the energy levels we can currently reach, and mathematically neither of them break down until we reach much, much higher energies than we're likely to see in any collider in our lifetimes (barring some revolutionary new design that comes completely out of left field.) There are some extensions to the Standard Model that predict things like supersymmetric particles that might potentially be reachable within the next generation or two of colliders, but while that would be plenty exciting in its own right it still doesn't get anywhere close to the energies we'd need to conclusively prove (or disprove) any realistic "theory of everything," (again barring something revolutionary that comes completely out of left field.) The scale difference between the SM and gravity is just too large to reasonably expect testability any time soon. So where does that leave science? Well from what I've seen, the consensus seems to fall on "testable in principle." That's certainly a much, much looser constraint than actual testability but its still better than completely throwing our hands up and allowing any random theory that manages to not put an infinity in a weird place.

The radius of the universe is ever increasing due to the expansion of the universe. So where is a constant here. And the speed of light in vacuum is variable ?

[@riverstun]

Equation 13:57 c = 2Pi f rp; but 2Pi r = circumference, so this says that c = f circumferencep. That is, frequency equals c divided by the circumference of the proton. So the number of times a particle would travel around the cirumference (per second) would be its speed (c) divided by the distance travelled (the circumference). If the speed of light were 10 million times the circumference, the number of times it would travel around would be 10 million (per second).

[@DrJens-pn5qk]

Since the speed of light is actually a property of space-time (we only call it speed of light because photons travel with that speed and they do so because they are massless) it is reasonable to assume that the time that massless particles need to travel across the universe remains constant. And since the radius of the universe is increasing, that speed increases with the same rate. I guess that would explain some observations that led to the assumption of accelerated expansion.

I devised the following approach from A-topology in resolving GR/QM conundrum. From A-topology: Theorem #1: In the class of generally ordered spaces, weakly perfect spaces are one and the only true generalization of perfectness; Theorem #2: The existence of weakly perfect spaces that are not perfect is almost a rule. A-topology is based on the following 3 basic axioms: Axiom #1: The set X and the empty set are open. Axiom #2: Any union of open sets is open. Axiom #3: Any finite intersection of open sets is open. Here are key insights and hypotheses: Each point in weakly perfect space W corresponds to a potential quantum state. The open sets in W represent the possible state configurations or superpositions of those quantum states. We define a function to map from W to a state in ℋ Hilbert space that defines the following condition for weakly perfect continuity: f(W) ⊆ ℋ is continuous iff for every open set O in ℋ, f⁻¹(O) is an open set in W. This condition ensures that the mapping preserves the topological structure of quantum states as conceptualized in weakly perfect spaces. Now, if we consider a set S in W comprising multiple points, each corresponding to a different quantum state, then the union of these points (U = ⋃ p_i, where p_i ∈ S) represents the superposition of these states. This union, being an open set in W, adheres to the properties of weakly perfect spaces. In terms of quantum entanglement, we can extend this idea further. If two particles are entangled, their combined state cannot be described independently of each other. In our A-topological framework, this can be represented by a set E in W, where the points in E are so intertwined that their corresponding quantum states in ℋ are non-separable: For p, q ∈ E, the states f(p) and f(q) in ℋ are entangled iff f(p) ⊗ f(q) ≠ f(p) ⨁ f(q).

[@nafeesaneelufer5023]

Excellent presentation Sir. Ru/rp is 10^39. But we know that the universe is expanding, which means Ru is keeping on changing. So in order to maintain the ratio constant at 10^39 then rp radius of proton must also be changing. Mu/mp is 10^78 and if mp mass of proton changes then mass of the universe must also be changing. So is rp only changing or both rp, mp is also changing or else is the number of paticles in the universe changing. But protons are not the only particles in the universe there some others like mesons, kaons, electrons also then we have to consider their masses also for finding number of paticles in the universe.

You hit the point. Actually, 10^39 is what Dirach called the epoch, and of course, it is increasing. He suggested a variation of G, which is not ruled ot completely. The interesting thing is the particle number. A solution going back to Rober Dicke is presented in www.amazon.com/dp/B01FKTI4A8

@@TheMachian Along that line, it is easily derived that if the mass (aka number of particles) is increasing, it should be at a rate proportionate to sqrt(t). This implies an expanding universe. There's reason to believe that this does not hold close to t = 0, but observeables at low t are scarce. Possible inflationary early universe via large mase in small spare => more space. Per latest standard gravity theory, as one approached the event horizon, the light from the outside narrows down to a single point, away from the 'center' of the black hole. Non-standard (but calculable, and per standard theory not observable from the outside). Inside, 'down' in polar coordinates becomes 'future' in time, and the former time dimension becomes spatial. The entire event horizon becomes 'the beginning' of time, and is a horizon, not a singularity. But mathematically, the entire universe outside the event horizon diminished to a point at the event horizon. Using one set of equations of the metric (metric from calculations of the inside, but not accounting for z to t axis rotation) , gravity pulls us to the future. Locally, we would observe the arrow of time. Thus the observed speed of light is dependent on gravity. Since the gravitation curvature in that metric increases monotonically, time should slow. At this point, I run out of skill to calculate, but first estimate is Lorenz contraction, and thus in this metric it appears to slow time, which is isomorphic to hyperinflation of distance. I can get to ... Dirac's large numbers. Also equates to watching the area just above the event horizon,

[@longlostwraith5106]

What is your opinion on EWT's take on gravity? According to the theory, gravity is a shading effect between particles, as a tiny portion of inbound longitudinal waves are converted to transverse waves due to the particle's spin. I'm bringing this up because it correlates with Dirac's realization that the strength of gravity is related to the mass and size of the universe. Every single particle in the universe "produces" outbound longitudinal waves, which then strike an observed particle from all sides equally if you ignore shading. But because of shading, the more waves per unit volume you have, the more pronounced the shading becomes!

Reliance on the proton mass (and proton radius) in dimensionless cosmological ratios, if not considered mere coincidence, would seem to indicate that the geometry of gravitation is dominated by the geometry of particles that are geometrically similar to protons (eg nucleons, ie protons and neutrons). If so, and if dark matter dominates gravitational matter, this would imply that dark matter is predominately baryonic (eg nucleons, ie protons and neutrons). AFAIK, this is inconsistent with the lambdaCDM model of cosmogony.

[@jaredclassical]

Although interesting, using dimensional analysis (numerology if you will) to relate concepts isn’t always an effective method of hypothesis or proof. Just because the orders of magnitude of the ratios (F_e)/(F_g) and (R_u)/(r_p) are the same doesn’t mean they are in any way related by the same physical phenomena. The first ratio is related to classical mechanics, which is dependent on the inverse square law, while the second one invokes scales that relate to GTR and QM. With that comparison, you’re relating a classical physics ratio to a modern physics ratio. Not to mention that the orders of magnitude you’re showing are so massive (10^39) that the values of each ratio can be that much more massively different from each other than those approximations elude to. The difference between 1 (10^0) and 2 (2*10^0), numerically, is much smaller than the difference between 100 (10^2) and 200 (2*10^2) so those compared ratio values, at those magnitudes, matter if you’re invoking them in your hypothesis/argument.

[@TheMachian]

I didn't say *always*, and certainly these hints are no proof. The need something else the same way eps0 mue0=1/c2 needs Maxwell's theory. The fact that the numbers involved are so huge justifies to consider orders of magnitude. And don't forget tehre are 2 coincidences, not one. I can also recommend reading Dirac's original 1938.

[@jaredclassical]

Unzicker's Real Physics By *always*, I wasn’t referring to you specifically, only in general, through dimensional analysis, that it isn’t always an effective methodology of hypothesis and/or proof pertaining to Physical Arguments. To begin, Maxwell’s theory predicted that the speed of an electromagnetic wave was the same as the speed of light and he argued, theoretically, that light was a propagating electromagnetic wave. The speed of light was first measured by Roemer in 1676 and it was remarkable that Maxwell’s theory had that value spill out with mu_0*eps_0=1/(c^2) as it was the speed coefficient of his derived wave equations, solutions from his 4 proposed field equations. That speed doesn’t *need* Maxwell’s theory and Maxwell’s theory didn’t *need* that speed; it was a remarkable result of his theory. I made the comment about orders of magnitude because I have read Dirac’s paper where he clearly states that these values may be dependent on which Epoch we exist in. His theory was a first approximation based on that these ratios are constants. Dirac even cites that his theory may need to be amended as it ignores factors that *may vary slowly with their arguments.* He even states that the *general formulation of the principle does not enable one to draw exact conclusions with certainty* where he then asserts with Eq. 1 that *a* does not equal *kb* (where a and b are of the orders of magnitude 10^39, and k is a constant of order unity). In that same section, he concedes that these *numerical coincidences* are off by a few orders of magnitude and that these coincidences need to be ignored *for the sake of getting a definite theory*. By in large, these orders of magnitude are massive enough to toss out their coefficients but are tiny compared to the size and structure of our observable Universe where all observable physics works. Additionally, these approximations are also based off of Spiral Galaxies (Nebulae) and their structures, not the radius of the Universe. These are not even the most common type of galaxy, Elliptical Galaxies are. Elliptical Galaxies are also the largest galaxy structures (Giant Ellipticals) in the observable Universe. Furthermore, using the ratio of the mass of the Universe and the mass of a proton ignores a major conservation law in Physics as mass, strictly speaking, is not a conserved quantity; energy is, a result of STR.

[@DanielL143]

I agree, as relates to string theory. String theory is an elaborate mathematical approach to metaphysics that can never be empirically verified. Science as an empirical endeavor is either seriously off course or at its inherent limits from the perspective of our scale in the universe. We need to bring metaphysics back to the point where it can drive physics forward in a sensible way. Q1 - The problem with Dirac's approach is that the Mass and size of the Universe are still not well established by cosmology. Q2 -"Gravity originates from the distant masses in the universe" sure sounds like spooky action (back to metaphysics)?

Ether Theory Revisited: The speed of a wave in classical mechanics is related to the energy/lenth in the media. (ether-stress) In the case of electromagnetic waves, the media is the vacuum and the speed of light might relate to ether-stress. The ether-stress might, in turn, be related to the inflation of the universe. Lorentz contraction might also be partially attributed to some quality of the vacuum. Since we measure both distance and time by counting wave-lengths, c is a constant if/when wave-length contracts appropriately. But the ether is not like a gas, it is more like a membrane or boundary in a 4th dimension. On the other side of the membrane, anti-particles mirror our own observables. The interactions with the membrane and anti-particles explains pair-production and annihilation. Perhaps gravity emerges as a manifestation of ether-stress. And ether-stress, in turn, is locally affected by the presence of particles (and the tension / pucker) they produce in the membrane.

[@reasontruthandlogic]

The real reason for looking for an equation showing an approximate numerical relation between one known constant and other known constants in physics would be to suggest a direction of research which might lead to an /analytical derivation/ of that equation, thereby reducing by one the number of arbitrary constants. While any such simplification would always be welcome, it should always be remembered that pure mathematics can tell you absolutely nothing about physical reality. In other words, there will always be at least one unexplained constant in physics, because a mathematical model which is not linked to reality by at least one of its parameters being arbitrarily equated with some measurable physical quantity, by way of an arbitrary scale of measurement, has no link with reality. The nearest thing we can ever hope for to a genuinely universal theory of physics would be one in which the only assumed laws were the current laws of human thought. These are the laws on which mathematics itself is based, or was at least derived from. They include mathematical ideas about number, arithmetic, geometry, topology, and such like. Attempts have been made reduce these to as small a logical basis as possible in set theory and logic, but as with physics, even mathematics cannot pull itself up by its own bootlaces. Note also that even such a theory would only be universal amongst humans, or possibly amongst thinking beings.

[@tulliusagrippa5752]

The size of the visible universe increases with time. Does the radius of the proton increase with time? If not, why is this ratio important? Interestingly, the video is titled “way to quantum gravity” yet you say nothing about how one might get to a theory of quantum gravity. Why is that?

[@TheMachian]

No, I don't believe the proton radius in increasing, if one tries an encompassinc picture of variable scales as outlined in my book "Einstein's Lost Key", it appears to even decrease. Thus the Dirac numbers would be (slowly) variable, yes. I did not claim to have a theory of QG, nobody has. I just said Dirac's work is the only reasonable ide in this direction.

Dirac published when the picture with galaxies was still new and generally fuzzy. There are three different gravity/electrostatic force ratio large numbers possibly worth consideration. Proton-to-proton (~10^36), proton-to-electron, which is ~1836 times greater (~10^39) and electron-to-electron, ~1836^2 times greater (~10^42). Rescaling proton size using these three numbers respectively gives a scale close to spiral galaxies, a scale maybe close to a lot of galaxy cluster sizes, and a scale larger than the observable universe. The only obvious coincidence I can see is with galaxies, not to suggest the other two lack any merit. Nonetheless the ~10^39 LNH approach seems distractive relative to proton-to-proton couplings. With proton-to-proton ratios it's a structural energy balance of sorts, R(p)F(e)=R(spiral)F(g) linking a wave-space of ubiquitous charged baryons with a wave-space of ubiquitous galaxy-sized bosonic quantum-gravitational wavelets, maybe. I could talk about what is wrong with physics all day while still lacking the math chops to come up with a good explanation for Hydrogen mass, but that doesn't mean my criticism forever lacks valid utility in helping to unlock that riddle.

[@TheMachian]

Evidently, the factor 1836 is in there. Yet I consider it the most natural thing to look at the p+ e- , it is the hydrogen atom, after all. There is no way to reconcile the square of any number, be it 10^36 to anything else then the mass of the entiure univserse. I agree however that the matter is not settled.

Dirac was pre string theory matching quantum mechanics with relativity but not stressing space volume measurements and distance and particle mass just relationships between components. Showing the wave nature of string vibrations and harmonic relations of forces and size.

The main problem is that it is impossible to develop a quantum field theory for gravity using renormalization, but perhaps there are other ways, as long as another prescription is applied in QFT I suppose. Either that, or the idea of a gravitational particle is absurd.

Renormalization is a flawed concept anyway. I agree with Dirac.

Hello, Alex, I wonder what you think of this. I have, for years, thought of Dark Matter or Dark Gravitation as a form of surface tension. Recently I saw a Max Tegmark video where he rehashed Galactic Clusters passing through each and leaving mass behing, which had collided in the passage, but the Dark Matter passed straight through, did not join together or carom back. And the there's the hypothesis that Dark Matter is responsible for production of Gamma Photons that make up the galactic Fermi Bubbles. I immediately let surface tension fall away because this is not surface tension and I immediately quit believing it could be surface tension. Gamma Photon production is a reaction to Positronium annihilation. But Positronium is difficult to prouce, and that's a lot of Gamma Photons. A lot. So I started plugging the loose ends that had dismissed surface tension into new nodes, assuming Dark Matter had to be some kind of hitheto unimagined antiparticle. And what Max Tegmark said was almost identical to something I had heard Jim Gates say. If two different phenomenae can be described in the same way, it is likely they are the same thing. It seems to me that light passes through light in exactly the same way Dark Matter passes through Dark Matter. I imagined an antiphoton that behaved exactly like a photon in every conceivable way except that it radiates backward in time. So I looked up antiphoton to see if anyone had postulated such a thing. I found that the accepted term is "Dark Photon". Seems that, just this year, 2020, a lot of scientific papers have been published on this subject of Dark Photons, proposing it as a candidate for Dark Matter, including--just on 9-23-2020--a proposed experiment to hunt for them in S. Korea. It seems (to me) like this one tweak to the SM could solve just about every mystery in the universe, from Q-Grav to consciousness to Dark Matter. I wonder, please, could you share any thoughts on this? Thank you for reading to the end. Sincerest regards, Allex

[@TheMachian]

Hi. DM is a profound riddle. I personally would try to relate is to modiefied dynamics (not MOND) due to variable speed of light, but I haven't got a good solution yet, honestly. I am also skeptic of the approach outlined by you and Tegmark, but who knows, I can only encourage you to pursue. The bullet cluster (much advertised) in not really a proof, tehre is also Abell 522. Special cases. An excellent overviem is the book by R. Sanders "The dark matter problem". Best,A.

Another interesting "coincidence" is the ratio of electron to light quark mass (ke^2 / hc), and the fine structure constant (2 pi ke^2 / hc),, where the masses in the former are derived.

[@onehitpick9758]

In addition to not doing numerology on a wildly moving target like the universe mass, we cannot derive any of the fundamental constants in physics -- not just alpha. They are all elusive. The very first mystery to solve is the electron (like charge and mass). The proton is an incredibly complex, composite beast compared to the electron.

[@TheMachian]

Why should constants be illusive? Calling the proton inbcredibly complex is also a faith-based statement.

[@onehitpick9758]

@@TheMachian I have seen an interesting derivation of the electron mass and charge, based on the assumption that the electron was a black hole (Kerr metric). It was not spot-on, but close enough to be interesting. But in reality, we are missing a striking amount of basic knowledge (thus the elusiveness). The first thing we should be seeking is the origin of the electron mass and charge. It should fall out of a set of field equations, quantized or not. As for the proton, it is a beast. Though we don't know it's decay time, it's harboring stuff. The standard model and particle physics and all high-energy probing suggest it is composed of 3 quarks, and if you get close enough you see evidence of something that's not purely a spinning charge. It's a composite "particle", and it probably hides some of the missing positrons in our area of the cosmos.

[@OneLine122]

It seems normal to me? If you take the formula E= mc2 The speed of light is a measure of distance in modern physics. So that F ~ c would make sense? Now you put into proportion F, so you get the radius of the universe over the radius of the smallest thing with mass, the proton and you get that number. I would say it's the same force, but one is very condensed, while the other is very diluted. Take all the gravitation in the universe and put it in a proton, you get the electro-magnetic force. It's why the proportions are reversed. For the mass, it's the same, but now you use the original formula. So you multiply by c and get this new ratio. Probably because those fields are in two dimensions instead of force and distance? In this case we are talking about energy of both really. It does suggest something like what Mach was trying to say. It's like the whole Universe puts pressure on things from all sides and this create the electro-magnetic forces and nuclear forces, which makes sense (to me at least). It's like if an electron has to get away from another charge, it has to fight the whole Universe type of thing. What we consider gravity like the Earth's is more of a local thing, but there should be a universal gravity. If that's true, and if it's true that the Universe is in expansion, that force should change as well. c should change, but the ration might be the same. I don't know if it has an actual causal reality though, it could be just math.

Let's say that we can find a better way if electron mass /4.26 -16) squared x 6.079-41n=3.02-40 n for n=1 in hydrogen that is the g radius for our electron but like the proton in hydrogen when it's orbital radius changes it's particle radius changes so that it's g radius will decrease to 3.02-16 met at n=2

Let me remind you another 10^78, it is estimetaed that during the cosmic inflation period the space expanded about 10^78 times, and that in about 14billion years after that it has still not expanded as much as it did in that extremely tiny period of time.

[@TheMachian]

The problem is that for that assertion, there is no data... inflation predicts, if anything, a lot of weird stuff. Dirac's idea is appealing, inter alia, for the reason that it makes cosmic inflation superfluos, because given a certain dependence of G and c, the universe is "flat" by definition.
