TOPIC: Einstein's Real `Biggest Blunder': Reveals Itself from the `Bits' by Ram Gopal Vishwakarma [refresh]

Information is fundamental to the physics of the Universe and we can indeed realize John Wheeler's dream. This is exemplified by unearthing a missing link of Einsteinian gravitation from a foundational analysis of some physical information, which appears revolutionary. It is realized that the introduction of the cosmological constant was not the `biggest blunder' Einstein ever made. Rather it was the introduction of the energy-stress tensor in his equations through which the source of gravitation/curvature is represented. This became the source of various problems, inconsistencies and unsolved puzzles in his theory, which are generally overlooked. It is shown that the energy-momenta-angular momenta of the gravitational and the material fields are built-in ingredients of the geometry of the so-called `vacuum' field equations and the energy-stress tensor is a redundant part of Einstein's equations. Baffling as it may seem, nevertheless the new discovery appears as a linchpin for understanding many unresolved problems in a unified manner. Moreover, the new paradigm gets strong support from observations ranging from the solar system to the Universe without requiring the usual epicycles of the standard theory, such as inflaton, non-baryonic dark matter and dark energy.

Ram Gopal Vishwakarma is a professor at the University of Zacatecas, Mexico. His research is focused on gravitation, with a particular interest in the foundational issues in general relativity.

Dear Professor Gopal

I skimmed through your essay soon realizing it was too technical for my full understanding. Having said that I have long been advocating an alternate way to look at GR - one first enunciated by Eddington - namely to regard the gravitational field as a density gradient. In that way the passage of light in it would be as in an optical medium with variable refracting index. I have incorporated this theory in a qualitative way in my 2005 Beautiful Universe Theory . Another objection I would have to GR is this: Einstein expressed his key discovery, that gravitation and acceleration are equivelant, using the flexible spacetime paradigm of Special Relativity, causing enormous unnecessary complications. It was wrong to base GR on SR for three reasons: 1- No observer reference frames are involved when, for example the curvature of the geodesic in a gravitional field is considered. 2- As Einstein himself admitted, in GR light slows down as it curves, contradicting a premise of SR. 3- SR banishes the aether, while later Einstein himself (Leyden lecture) and now modern physics demands it be reinstated, for example in the form of a Higgs field.

Einstein reached the right results through the wrong premises, and this is now causing many problems in physics. Read my last year's "Fix Physics!" essay outlining some of these ideas.

In conclusion I wish you the best of luck in gaining recognition for your objections about GR. Einstein's Relativity seems set in stone - particularly in the ossified brains of generations of physicists too lazy to question fundamentals and seek a way out of the current dilemmas in physics.

Hi Prof Vishwakarma,

The argument that you present is easy to comprehend, and boils down to - mathematics does not lie. Your hint that a paradigm shift may be necessary has been asserted by many others. However I fear, before such a shift takes place major new breakthroughs in both mathematics and theoretical physics are necessary; our present physics paradigm is limited by the mathematical structures available.

I commend you on a courageous essay - full marks from me - and join Vladimir in wishing you success.

Ram,

I have had the honor of rating my fellow contest participants by comparing my empirical findings (not opinions) with statements made in the essay. Typically I find up to a half dozen key points that express the strength of the positions expressed. Your essay is truly an exception in this case with at least a dozen key points found, as such, I am pleased to rate highly.

It appears we have a common perception based on the use of curvature. Although my approach goes one step deeper, I believe you will find it of interest and I hope you will take the time to review and rate my essay accordingly. I believe you will find it provocative and relevant to your efforts:

Prof. R.G. Vishwakarma,

Your essay is interesting and clear, showing that even the Ricci flat solutions in General Relativity are rich. I think that this is mainly due to the presence of the Weyl tensor, which, even when Ricci is 0, in general is not 0. I think it worth seeing how far can we go with Ricci flat metrics. Wheeler in fact considered as a version of his geons, those made of self-gravitating gravitational waves (hence of the Weyl tensor), in the hope to describe particles. Other approaches based on Ricci flat metric are studied in some versions of Kaluza-Klein theories, where the degrees of freedom are enriched by adding extra dimensions.

Cristi Stoica

Dear Cristinel,

Thanks for your kind remarks. Riemann tensor can also be non-zero when Ricci tensor is vanishing. That will signify the net energy-momentum-angular momentum of the material and the gravitational fields at a point.

Prof. R.G. Vishwakarma,

Thank you for your reply. You said "Riemann tensor can also be non-zero when Ricci tensor is vanishing.". When Ricci=0, Riemann=Weyl, so we are in complete agreement.

You mentioned the Kasner solution, and that the matter source (the singularity) exists only at the time t=-1/n, and yet it has effects at other times too. This in fact happens in the Schwarzschild solution as well. The singularity r=0 is not necessarily in the present of an observer affected by the black hole's gravity. This is obfuscated when using the Schwarzschild coordinates, but it is visible for example in the Kruskal-Szekeres coordinates. Another remark: I think something like this happens with the electromagnetic field. Imagine a pair electron/positron attract each other and annihilate. Yet, the electromagnetic field sourced by their charges exists an indefinite time after they were annihilated.

Best regards,

Cristi Stoica

Thanks for reminding me that the Weyl tensor (with 10 independent components) can be thought of as containing the information of the Riemann tensor (20 independent components) minus that of the Ricci tensor (10 independent components). So in the case of the vanishing Ricci, Riemann=Weyl.

Respectfully Professor Vishwakarma,

Einstein’s biggest mistake was his not realizing that one real unique Universe can only be eternally occurring, once. He knew nothing of real unique, once. He only speculated about common abstract repeatability. Although abstract energy can equal mass times the constant speed of light squared once. As I have pointed out in my essay BITTERS, one real Universe only uses real absolutes. The absolute of real energy must be the real Universe, always once.

Dear Satyavarapu,

In my essay, there is no problem of the violation of the conservation of energy or matter coming out from nowhere. If you read the article and the references therein, you will note that there are two time scales in the resulting cosmological theory. In terms of one of them, the universe becomes infinitely old without any singularity at any finite time in the past. So, the question of the origin of matter/universe becomes meaningless in this model.

Dear Ram,

Well argued, using the very tools used to construct the GR theory itself.

"on the basis of the general theory of relativity, space as opposed to 'what fills space' has no separate existence".

My view: space is both the content and the container, so I agree what fills space and space itself are the same. You can criticize and fault my essay so I can improve it. Thanks.

Dear Dr. Vishwakarma,

Your does illustrate one of the weaknesses with general relativity as a complete theory. In source free regions we can be reasonably sure that solutions with certain symmetries are physically correct, and the Hawking-Penrose energy conditions are upheld. The Einstein field equations though permit all sorts of quirky solutions, including those that are time machines.

The Kasner solution is a simple case of Mixmaster or Bianchi type cosmologies with anisotropies. The anisotropies are interpreted as due to gravitational waves that behave as if there is a T^{00}, which is a sort of internal energy in a source free region. These models have not been prominent of late, but data involved with CMB anisotropies seem to suggest the early universe may have had properties of this sort. These anisotropies may have been a part of the physics with particle production.

I think that geometrical or topological decompositions of four manifolds constructs topological quantum field theory, or formalism equivalent to that. The matter which fills spacetime is then equivalent I think to this underlying structure to spacetime. Einstein was dismayed by the apparent asymmetry in physical meaning between G_{ab} and T_{ab}. I think the underlying problem might be addressed by thinking of spacetime has having all the substructure of particle physics. The production of particles in a Mixmaster type cosmology from anisotropy does suggest something of this nature.

Cheers LC

Dear Lawrence,

Thanks for your kind and knowledgeable comments. It would not be correct to say that all the solutions of Einstein equations are not meaningful. This will create doubt over the general validity of the theory. Then how can we be so sure that Schwazschild solution (for example) represents a meaningful solution. Just because, it seems consistent with experiments? May be, we have been unable to interpret other solutions correctly, which we claim unphysical. As an example, the Kasner solution (which is considered unphysical) in the new paradigm discovered, in the paper, represents a real big bang universe!

Dear Professor Vishwakarma,

I read your essay with interest. I liked the term "geometrization of matter" - something I can relate to from my previous work with simplexes. Also the possibility of omitting singularities in the Ozsvath-Schuckling solution agree with my analysis that information might avoid being lost forever in Black Holes.

Antony

Dear Professor Gopal

I have read your essay with a great pleasure. The reason is not only your style but first of all the geometrization of matter.

I have tried to apply Einstein’s geometrization concept (but not his equations) not only to the matter but also to all “force fields” i.e. electromagnetic, strong and weak nuclear. The gravity would then be emergent as a superposition. The job is not easy so I have proposed an experiment to be sure this is not a huge waste of time. As you know Einstein GR failed outside the Solar System distance scale ( so some physicists try to save GR by means of dark things) and Wheeler-deWitt geometrodynamics has the well-known flaws: the problem of time, the problem of Hilbert space and others. QM’s Standard Model in turn does not offer any metric. The other theories using canonical approaches (connection dynamics, loop dynamics etc.) or covariant approaches (perturbation theory, path integrals etc.) and string theories also have not acceptable flaws or generate no predictions.

I am looking for that one, universal, distance scale invariant metric (eventually reducing to Einstein GR metric within Solar System distance scale) and having ability to generate predictions. The first prediction of that geometrization concept is my spin experiment outcome. Depending on the outcome we shall look for a proper metric or give up.

GR has no action at a distance and QM has. If we assumed that any spacetime deformation is unlimited (to some extent it deforms the entire spacetime in Gaussian distribution mode, due to its elastic and homeomorphism properties) we have got non-local action! The Gaussian distribution guarantees no singularities for free.

In the contest is more than 100 essays so I would like to draw your attention to Torsten Asselmeyer-Maluga’s essay and his publications on the geometrization of matter.

Your essay deserves the highest rating. Good luck!

Best regards

The other theories using canonical approaches (connection dynamics, loop dynamics etc.) or covariant approaches (perturbation theory, path integrals etc.) and string theories also have not acceptable flaws or generate no predictions.

I am looking for that one, universal, distance scale invariant metric (eventually reducing to Einstein GR metric within Solar System distance scale) and having ability to generate predictions. The first prediction of that geometrization concept is my spin experiment outcome. Depending on the outcome we shall look for a proper metric or give up.

GR has no action at a distance and QM has. If we assumed that any spacetime deformation is unlimited (to some extent it deforms the entire spacetime in Gaussian distribution mode, due to its elastic and homeomorphism properties) we have got non-local action! The Gaussian distribution guarantees no singularities for free.

In the contest is more than 100 essays so I would like to draw your attention to Torsten Asselmeyer-Maluga’s essay and his publications on the geometrization of matter.

Your essay deserves the highest rating. Good luck!

Dear Jacek,

Thanks for your kind remarks and for your interest in my essay. I also thank you for mentioning Maluga's work on the geometrization of matter. I shall read them in time.

Best of luck on your ambitious endeavor. The theory based on R^{ik} = 0 might fit in it. It is scale invariant, describes not only the gravitational phenomena in the solar system, but the whole universe, as I have showed.

Best of luck on your essay.

A very interesting paper Professor Vishwakarma,

The ideas presented in this essay are indeed worthy of note. People have been so focused on finding a correct formulation for the stress-energy tensor, that they never bothered to examine solutions that make it unnecessary. Very fine work, and a paper well-written and well-enjoyed. I shall be happy to rate this one highly, once my own essay has posted.

Good Luck!

Dear Dr. Vishwakarma,

In your highly interesting article, you have argued why the elimination of the term Tik from the basic equation of GR is essential if we are to make sense out of it to explain its recent consequences. Here I consider only the Kasner solution. For me, it appears that the Kasner solution must be applied to the QG field which exists inside black holes and only then it is possible for us to make sense out of it. So Tik points to the existence of QG field but cannot explain it as the metric of GR gik breaks down in the QG field. It is thus possible for us to understand and solve the mystery surrounding the Kasner solution and I think there is no need to eliminate the term Tik from the basic GR equation as it would spoil the formal beauty of the theory. So the effort to retain Tik, lies in finding the basic equation of QG field and from which deriving the basic equation of GR.

Sreenath

Dear Sreenath,

Thanks for your kind remarks. I don’t understand how you can apply the evolving (time-dependent) Kasner solution inside a black hole represented by the static Schwarzschild (exterior) solution. The interior of a static spacetime is expected to be static. Anyway, the existing Schwarzschild interior solution, providing the standard representation of the interior of a static spherically symmetric non-rotating star, turns out to be unphysical, since the speed of sound (dp/d\rho) becomes infinite in the fluid with a constant density \rho.

While beauty should not be considered as a decisive factor for a physical theory, you seem to be unaware of the very Einstein’s remarks of "low-grade wood" for the energy-stress tensor and the "fine marble" for the geometry (as he put it in a 1936 article in the Journal of the Franklin Institute). Thus shunning the “wood”, ENHANCES THE BEAUTY of the “marble” in the extreme simplicity of the field equations R^{ik} = 0!

Prof. Ram,

Your essay is near and dear to my heart (as I am interested in how field theories are mathematically represented and the Cosmological Constant problems). I have some questions concerning your essay:

1. You state "in the absence of which the solution must have a singularity, serving as the source". What singularity are you referring to? I know of the singularity that arises in linearized gravity but that is based on

. (I am not yet familiar with Osvath and Schucking so will have to review their material).

2. Your equation 4 uses an M which seems to be based on the Poisson equation definition of energy density within a volume. I see your disclaimers on LambdaCDM not conforming with the Poisson concept of energy density anyway but you seem to be equating the energy density of a gravitational field with the same energy density that mainstream physics is using for "vacuum" energy density. True or no?

3. How can a constant of integration represent the energy density of a gravitational field since the constant wouldn't change but the gravitational field would need to in order to do work on regular mass?

Dear Jeff,

Thanks for your wonderful remarks and interesting questions. My explanations to your queries are the following.

1. I’m talking about the full GR and not any of its approximations, such as the linearized gravity. It is the conventional belief that the curved solutions of R^{ik}=0 (i.e., the solutions of Einstein’s eq (1) in the absence of T^{ik}) must have a singularity. For example, the Schwarzschild and Kerr solutions have singularity at r=0, the Kasner solution (5) has singularity at t=-1/n. But this conventional wisdom does not seem correct as the Osvath-Schucking solution (a solution of R^{ik}=0) is curved but it is singularity-free.

2. The value M in eq (4) comes by comparing geodesic equation in GR (considered in the case of a weak gravitational field) with the Newton’s equation of motion. This gives the metric potential g_{00} in terms of the Newtonian gravitational potential. Remember that in the case of a weak field, eqs R^{ik}=0 reduce to the Laplace eq and not the Poisson eq. Though both these eqs (Laplace and Poisson) use the scalar gravitational potential, but in Poisson eq, it comes from a matter distribution, while in the other case, it results from a point mass [as in eq (4)].

3. If you read carefully, you will find that the gravitational energy is represented IN TERMS OF the constant K, and NOT “by the constant” K. It is in fact K/r [(see the lines preceding eq (4 )].

Dear Professor Gopal.

Thank you for a very nice essay. Key highlights for me were:

1. The total energy of the universe must always remain zero.

2. Einstein quote {for GR} "space as opposed to 'what fills space' has no separate existence". I assumed Einstein believed the opposite, I was pleased to hear I was wrong.

3. The observations actually reveal a simpler and more elegant Universe than anyone could have imagined!

Congratulations on an original set of ideas, cogent explication and those wonderful snippets of education.

My only criticism - this was much more about General Relativity than the subject of the contest (It from Bit).

Dear Ram,

Thank you for your interest in my essay. As noted on my page, I believe our theories are compatible and I am working to show this.

You have re-analyzed Einstein's full field equations and concluded that R_{ab} = 0 does not represent 'empty' space-time, as it produces 'curvature', and therefore must represent at least the gravitational fields which, in my opinion [and Einstein's], 'define' or 'make real' space-time. You suggest the fields are represented in the equations through their non-linearity. Of course! What else could represent the self-interacting field?

My approach has been to assume initially one field, with no 'matter' sourced, and attempt to solve the evolution of this field. Except for the initial state of perfect symmetry, I have not focused on cosmological solutions but on particle creation. In particular I have worked with the 'linear' weak field equations which, however, represent a field that is inherently nonlinear. So I have attempted to 'add back' the non-linearity, but in a form that offers new solution possibilities. The jury is still out.

I find your analysis and your arguments compelling, most particularly:

"The fact that the sources of curvature are implicitly present in R_{ij} = 0 and must not be added again (through the stress-energy tensor), is vindicated by the failure to obtain a proper energy stress tensor of a gravitational field."

I'm very excited about your new theory, and believe it offers great promise in a time of great confusion. A stress energy tensor that does not incorporate the stress of the field's non-linearities cannot be the answer. Your approach looks like the answer to me.

My best regards,

Edwin Eugene Klingman

Dear Edwin,

Thanks for your wonderful remarks! By the way, mine is not a new theory. It is just the resurrected version of GR. Einstein barely missed it. He did this twice: first, when he discovered that the energy-stress tensor was the `wood’ portion of his grand edifice of `marble’. Second, when he couldn’t find a proper energy-stress tensor of the gravitational energy. Had he not gone astray, he would have discovered that the concept of the energy-stress tensor is not compatible with a geometric theory of gravitation [Astrophys.Space Sci. 340 (2012) 373-379].

One should also note that not only the gravitational energy, but the matter field (which is the ultimate cause of the gravitational field) also appears in equations R^{ik}=0 without including the energy-stress tensor. The source mass M appears in Schwarzschild solution, through a constant of integration, without including the energy-stress tensor. (Though GR is not sufficient for this identificaton and we have to invoke extra assumptions. For example, in the present case, we assume that GR should reduce to the Newtonian gravitation in the case of the weak field.)

Best Regards.

Dr. Vishwakarma,

An out of the box look at GR is long overdue, especially with the continuing mystery of gravity, black holes and the BB. Your essay was challenging but remarkably clear for an unschooled, yet newborn physics zealot such as myself.

Empty space is not bereft of energy and does seem to engender gravity, perhaps perturbed by virtual particles. That is my image in portraying the BB in my essay and its occurrence, absent of conscious observation.

Dear Peter,

Thanks for your kind remarks. I hope you may also bear with me if I suggest that we require a theory which can answer why the world is there and why we are here! Then your proposal, or any theory of quantum gravity, would become “incomplete and flawed” in your terms!

I have kept limited myself, in the present essay, to only the most successful theory of gravitation, i.e., GR. However, there are hopes, in the proposed framework, for further developments, on which I’m working. You know that one of the most common ways for a particular theory to be renormalizable is to be scale invariant. And equation R^{ik}=0 (on which the proposed paradigm is based) presents an scale-invariant theory!

Ram,

I quite agree your model may be only 'slightly', but mine may be entirely 'flawed', and almost certainly is: "All we know will ultimately be revealed as false." The best answer I found to why we may be here is Richard Nixeys, we are an organic experiment, which may be called a 'computer' to find out why the scale-invariant greater universe exists! Yes, I agree scale invariance is essential. But I think there are questions we CAN answer which we yet have not.

I think that is the reason we postulate theories, to be falsified, and that is the reason I would like you to read my essay; so you can judge for yourself. I confirm I was very impressed by your work and believe I will greatly respect your views.

Very best wishes and thank you.

I think that is the reason we postulate theories, to be falsified, and that is the reason I would like you to read my essay; so you can judge for yourself. I confirm I was very impressed by your work and believe I will greatly respect your views.

Very best wishes and thank you.

Ram,

I do hope you may get the time to also read my essay and comment. Both having read each others seems an essential requisite for useful communication.

You also may be able to guide me on the areas I see commonality with my more geometric, epistemic and and heuristic ontology.

I think your work is valuable and hope my score may help it make the final cut.

Very best wishes

Peter

Hi Ram,

Thank you for a very intriguing model of gravity. You wrote:

> It would be interesting to note that a homogeneous, isotropic cosmological solution of equations (2) becomes Minkowskian.

In my essay Sofware Cosmos, I describe a computational model for the cosmos that answers many cosmological puzzles. One important distinction in my model is between the "explicate" order (which is Minkowskian) and the "implicate" order which is conformally compactified Minkowski space.

My hypothesis is that it is the curvature of the implicate (rather than total energy) that is responsible for the observed departures of gravitational force from the Newtonian. This can be calculated (via Gauge Theory Gravity) in a flat background and does not require the presence of matter. My picture also includes scale-invariance in the form of fractal structure.

I hope you get a chance to take a look and tell me what you think.

Dear Vishwakarma,

I have a question about the statement that equates K/r with gravitational energy of the field - In Newtonian physics it is not the energy of the field but the energy of a unit mass particle interacting with another particle of mass M, or the potential energy of the unit mass particle. Why and how are you equating it to the energy of the gravitational field?

Also, apart from the beginning sentence in the abstract I did not find much connection with the topic of the FQXi discussion - can you please say how you address that issue?

Thanks and regards,

Unnikrishnan

Dear Unnikrishnan,

Thanks for your interest in my essay. I am a bit puzzled by your first question, that why you ask such a trivial one. Is it not the potential energy of the unit mass (situated at a certain point in the gravitational field of mass M) by which we measure the gravitational (potential) energy of the field produced by mass M in the Newtonian mechanics? Is this energy not calculated in terms of the work done in bringing this (unit) mass from infinity to that point? And does this work not equal to –GM/r, where r is the radial distance between the source mass M and the unit test mass?

The aim of the present FQXi contest is to provide foundational, innovative and influential thinking on Wheeler’s dictum “it from bit”. Here `bit' stands for the information and `it' for physics of the Universe. In the introduction of the essay, I have framed a goal to show that a correct physical theory of the Universe (`it’) can emerge from the `bit' if perceived correctly. The rest of the essay is devoted to this goal only, in the spirit of the philosophy of the FQXi, and I did not find it necessary to mention the words `it’, `bit’, `information’ several times unnecessarily.

Regards.

Dear Ram,

sorry for the long gap in answering your question (I was on vacation with my family).

According to my ideas, matter is also part of the spacetime (a part of the 3-space). So verything is unified: spacetime and matter, Bit and It.

Best

Torsten

Now more:

I like your essay. You also went along the usual way not modifying the spacetime (to be discrete etc.) I rated it a longer time ago very high.

So Good luck and Best wishes

Best of Luck for the Magnificent Eight !

I am throught the 180 essays, all rated. For me 2/3 of them were poor and other 1/6 curious. The rest (1/6) have I rated over 4/10.

You are among the authors of the top essays from my sight - alphabetically :

Corda, D'Ariano, Maguire, Rogozhin, Singleton, Sreenath, Vaid, Vishwakarma,

and I hope one of you will be the winner. (Please, don't rate my essay.)
