TOPIC: Dark Energy or a Simple Mistake: Do We Understand How Non-Unique the Einstein Tensor Actually Is? by Jeff Baugher [refresh]

TOPIC: Dark Energy or a Simple Mistake: Do We Understand How Non-Unique the Einstein Tensor Actually Is? by Jeff Baugher [refresh]

The cosmological constant, within the Einstein field equation (EFE), is the leading method to account for the discovered accelerating expansion of the universe, whether or not an underlying cause is understood. The Einstein tensor within the EFE has proven to be the only tensor that meets a number of properties (divergence-free second rank tensor, etc.) as derived from the Riemann curvature tensor and the metric g. We point out however, simply from summation of tensors and the fundamental theorem of calculus, that this uniqueness of properties does not extend to a differential equation with a non-zero constant of integration. It is important to fully understand why these properties are required to maintain our current cosmological model of attractive gravity. If this were in error it would raise profound questions of how the accelerating expansion relates to not only a gravitationally repulsive cosmological constant, but to our entire understanding of physics.

The author is currently a PhD candidate in Dayton OH USA, after receiving his BSEE in 2008. Recently, during dissertation research, he became interested in elasticity tensors, the history of field theory and the paradox of the accelerating expansion.

In addition, for those interested in Lorentzian Ether Theory, I used the following forum to help me work through pedagogical difficulties, ways to simplify my argument to a few pages and to gain feedback on any logical inconsistencies.

After conversations on here, it may be useful to have a simple graphical understanding of how positive curvature can produce either attractive or repulsive gravity. Simple sketch picture is attached. Only one of these naturally produces a dark energy effect.

Jeff,

You commented about my essay about the unification of gravity with the electromagnetic force and mentioned that my essay dovetailed with your essay. Actually, the book behind my essay covers a broader range of physics topics including the cosmological implications of using the starting assumption that the universe is only spacetime. With this assumption the expansion of the proper volume of the universe is explained as resulting from the transformation of the properties of spacetime. This transformation started with the Big Bang and continues today. This alternative model of cosmology entirely changes the perspective on dark energy and the cosmological constant. It is not possible to explain the implications for dark energy in this short post, but details are available here.

Dear Jeff Baugher,

Let me refer you to an excellent essay (topic 1372), titled "Misinterpreting Reality: Confusing Mathematics for Physics" by Robert H McEachern in this contest. He says, "Equations contain very little information. This fact is what makes it possible to symbolically represent them, in a computer memory, by a very small number of bits. As a direct result of this fact, we can conclude, contrary to the fervent belief of most physicists, that equations cannot describe anything other than the most trivial physical phenomenon; those nearly devoid of all information. For complex phenomenon, it is the vast information content of the initial conditions (like the content of an observer's memory) rather than the tiny information content of equations, that really matters."

In general, I agree with your arguments. However, in my opinion, main strength of the mathematicl model of GR, (including EFE) is that it can be adjusted to simulate the Newtonian gravitation with the additional provision that a finite speed of propagation of gravitational influence is built in the model.

Regards

G S Sandhu

Dear Jeff Baugher

Your essay was well written and I enjoyed reading it, I'll have to reread it again to understand some of your reasoning. This is why I like science we have so many different interpretations of what is real and what is an illusion. Some of the great scientist before us resolved some of these issues but by doing so they created more unresolved questions, that's where we come in.

In my opinion the paradox of the rapid expansion of the universe may be a simply process of universe rejuvenation, matter is broken down to its infinitesimally smallest parts, bosons, through the weak force interactions, black holes, supernova's etc where there diamagnetic-like mutual repulsion of each other is feeding the expansion of the universe. Dark energy and dark matter is said to make up as much as 95 percent of the universe and growing, yet we know very little about what it is made out of. The way I see it matter is radiating away at a much faster pace than we currently predict the universe will suddenly deflate (deflation) back into a singularity. The deflation won't be caused by gravitational influences, it will be caused by a universe wide collapsing condensate, Higgs field collapse.

As I said before Jeff I enjoyed reading your essay, good luck.

Ron,

Thanks for taking the time to read my essay. The goal I am striving for is to be able to take someone who has an understanding of calculus, give them a mathematical argument, and then let them be able to compare that to published literature on General Relativity prior to the discovery of dark energy. Section 17.3 of Gravitation by Misner, Thorne and Wheeler is probably the leading text and a great section to compare my argument to. Someone who is capable of doing this should come to the same conclusion as I, that the argument corrects a well known (but currently accepted since it came to fit our physical understanding) error induced into GR that comes about from putting the cosmological constant in, but also means that the physical models within GR cannot possibly be correct.

I agree with your sentiments on being able to consider arguments and analogies put forth in the quest to understand our universe. I look forward to understanding the arguments that you present in your essay also.

Dear Jeff,

I do not follow your ideas absolutely. What do you try to prove, or what you hope that your calculations will prove? I do not see meaning of your quantities Omega and L in equations (3) and (4). What they mean and what do you try to prove with them? Is vectorial r in eq. (5) and (6) unit vector? In opposite case r^3 should be in denominatror.

Otherwise, it seems to me, that you have good ideas with divergence free tensor G.

(BTW: Can you give, as expert, simple explanation for 8Pi factor in EFE?)

After reviewing the thesis some more, I would have to retract what I stated above. It does sound like I agree more with the paper they are criticizing. A specific reason why is if Omega g_{uv} is linked to the curvature potential/potential energy of all quantum harmonic oscillators for a point in spacetime, then L_{uv} would represent the remaining unoccupied states. Thus 8pi< T> represents those states that are occupied. Since I think that the Omega g_{uv}-L_{uv} is going to model gravity better, then I think that in a very real sense

Hi Jeff. A few useful remarks on your essay.

The way to unify gravity and electromagnetism requires balanced and equivalent attraction and repulsion and balanced and equivalent inertia and gravity.

The understanding of outer space is significantly limited, as it precludes and destroys thought entirely. You cannot get around this. A lesson to

FQXi.org as well. Telescopic observations make the unnatural/actually impossible experience of outer space even more incomprehensible. Telescopic observations do tell us something about how we see, however. We would never be able to survive long term/permanently in outer space, by the way.

Hi Frank,

Not sure how to use your remarks. It sounds more philosophical than physically analogous, which I am not adept at utilizing. I don't see an essay posted to the contest under your name. I pretty much get lost without at least some equations that are tied to mainstream theory. I don't view math as more important than analogies, but without that toolbox I don't see how to actually build any structure. The strongest argument is the simplest mathematical one in my opinion.

"The understanding of outer space is significantly limited, as it precludes and destroys thought entirely. You cannot get around this." The understanding precludes and destroys thought or outer space does? I don't know what that means, except I keep visualizing how some people during the industrial revolution were worried that people would no longer be able to think at the high speeds that the locomotive was theorized to be able to reach. How is our lack of evolving with unnaturally high speeds any different than outer space?

Do you mean that the human species (or perhaps any) has any hope of ever understanding the inner workings of the cosmos? That sounds utterly defeatist if so, and even if it were true I still would not stop searching.

Another analogy with epicycles...

Like the interpretation of perfect circles to the concept of orbits, we assume that the Einstein tensor is the only interpretation of the full field equation. If we hold onto the perfect circles, then every modification must take those into account. If we hold onto G_{uv} describing particulate matter, every modification to GR must adhere to that concept.

Hi Jeff:

I thoroughly enjoyed your concise and well-written essay.

Based on arguments and results presented in my paper - -“ From Absurd to Elegant Universe”, your following conclusion is fully vindicated:

“The cosmological constant, within the Einstein field equation (EFE), is the leading method to account for the discovered accelerating expansion of the universe, whether or not an underlying cause is understood. ……… If this were in error it would raise profound questions of how the accelerating expansion relates to not only a gravitationally repulsive cosmological constant, but to our entire understanding of physics.”

My paper provides a new fundamental understanding of the Cosmological Constant and relativistic universe expansion as an alternative to the widely accepted linear Hubble expansion. The current paradoxes and inconsistencies are shown to be artifacts of the missing (hidden) physics of the well-known phenomenon of spontaneous decay. A new Gravity Nullification Model for Universe Expansion (GNMUE) is proposed that integrates the missing physics of the spontaneous mass-energy conversion into a simplified form of general relativity. The model predicts the observed expansion of the universe and galaxies and other data. The model provides answers to key fundamental questions and resolves paradoxes among general relativity, quantum mechanics, and cosmology. It also bridges the gap between quantum mechanics and relativity theories via revealing relativistic understanding of the inner workings of quantum mechanics. The impact of the new understanding on widely-accepted fundamental assumptions is discussed and a new wholesome perspective on reality is provided.

I would greatly appreciate your comments on my paper.

Best Regards

The difference with what I am proposing is to replace the tensor T with a residual energy density. This would seem to be equivalent to just the energy momentum tensor of matter, but should solve some paradoxes. As for the WEC, this specifies that energy density cannot be negative. Since in this way I am defining energy density that we are familiar with as the difference between higher and lower positive tensors, it isn't a negative energy density.

Jeff. Life is fragile, and it is very precisely regulated and balanced -- this includes in relation to the direct experience of physical force/energy by the body. There is no surviving long term in outer space -- for an unlimited time with reproduction. That is a fact.

The direct experience of the force/energy of physics/physical experience by the body is fundamental/essential to the deepest, integrated, coherent, significant, extensive, and most fundamental ideas/theories/understanding(s) in physics.

My essay will be entered shortly.

The physical/full experience of outer space destroys us and precludes our thought and being entirely. Accordingly, our understanding of outer space is significantly limited. Thought cannot describe/approximate to what it is not, ultimately.

Perhaps there are areas of research that I was not aware of but that sounds very much like an opinion, rather than an actual fact. Citation?

I agree with the quote in your essay: "nothing short of a revolution in our understanding of fundamental physics will be required to achieve a full understanding of the cosmic acceleration." In addition, I do not believe that such a revolution can originate at any of the so-called top universities.

Hi Marcoen and thanks for the excellent questions:

(1) Perhaps I should state this as actually three different functions f_{1}, f_{2} and C. I do mean that C is a constant (i.e. a number) and not a function of x (i.e. C(x), a constant can still be integrated, so perhaps when I referred to it as a constant function this was misconstrued as meaning it to be a linear constant...

Forgot to answer: "You refer to figure 3 as an illustration, but what are the two scalar fields in the bottom picture physically? What is their physical source? What is the corresponding theory of gravitation (what is gravitation according to you)?"

The scalar fields are generic vector examples of Newtonian gravitational fields.

The first scalar field is a vector representation of the Omega (or equivalently the cosmological constant) term. It should actually be a scalar field with linearly increasing values radiating out in a circular fashion, but it complicates the explanation in that by definition gravitational force vector requires at least another mass. It is an isotropic pressure.

The second scalar field represents a vector formed from the gradient of stress energy tensor equated to L_{uv}. The field scalar values are of a much larger magnitude and the gradient is of an opposing direction, but of course the minus sign in front gives us an equivalent force vector to that of the regular Newtonian gradient. The illustration is to point out that the top vector field is what GR reduces down to in the weak limit, whereas the bottom two fields are closer to what is now empirically known.

Regards,

Jeff

Hello Jeff,

(1) If you write "f_{1} = C - f_{2}" then this is a relation between functions. That is, the term "f_{1}" on the left hand side is an element of a function space, and the term "C - f_{2}" on the right hand side is an element of a function space. That latter term "C - f_{2}" is the function obtained by adding the function "- f_{2}" to the constant function "C": in a function space, the binary operation addition takes two functions as an argument. If you want C to be a numerical constant (a number), then you can define the function "f_{1}" by defining its function value as in "f_{1}(x) = C - f_{2}(x)": this is a relation between numbers, so here C is a number (a constant of integration if you want). So subtleties in mathematical notation can make a big difference.

(2) I'm still having difficulties with the interpretation of your two scalar fields, illustrated by your figure 3. It seems to me that the first scalar field doesn't occur in the ontology of Newtonian mechanics. Isn't this something you want to add?

As a side note, in the framework of my own theory, the EPT, the observed space is a material substance which is transcended by matter waves (there are, thus, two different kinds of components). A metric may then be defined in terms of a difference between two scalars (close to what you suggest) but at this point it is not possible to conduct tensor algebra in this framework as the necessary mathematics have yet to be developed.

With best regards, Marcoen

Thinking about some of Marcoen's questions and I realize that my explanations aren't coming across clearly. Let's try this:

--In calculus, the indefinite integral of a given function (i.e., the set of all antiderivatives of the function) is only defined up to an additive constant, the constant of integration.

Suppose we take a measurement of gravitational force, lensing, etc. and we compare that to what our differential equations give us, and they agree for a given input. We are basically assuming that we are using the correct anti-derivative of our function.

Thinking about the hypothesized size of the cosmological constant, if , then from the definition of an indefinite integral, how do we KNOW whether this equation should be or If the second is not the correct choice, why?

If we take (da)²/a)+c²k/a²=8pi/3Gro+the energy of the quantum hole/3 .

Now if we insert the hubble law and my equations, you can correlate with the expansion/contyraction correlated with the maximum volume of universal sphere. Considering that the density can imply a contraction at this critical point.So we can see where the points of equilibrium are.The SR and the GR are ok and if we consider a system closed, it becomes relevant considering the number of quantum entanglement having the serie of uniquness.

See that the parameters must be precise for a correct universal dynamic. The volumes , spherical are essential like the rotations spinal and orbital.The proportions appear with mass. If the mass polarises the light and so if the entropy, physical increases proportional with mass.We can see where is this maximum volume just before the contraction towards the perfect equilibrium between all physical spheres. The friedman lemaître equation can be optimized.

Good work :) with the integrations, substitutions, extrapolations, additions, multiplications, settings,.......

"What could be causing this acceleration? Physicists call it dark energy, and it could make up more than 70 percent of the cosmos. But so much remains unknown about dark energy that some scientists are asking whether it exists at all.

What if, instead of a mysterious unseen energy, "there is something wrong with gravity?" asks Sean Carroll, a theoretical physicist at the California Institute of Technology.

Einstein's theory of general relativity represents gravity as the curvature of space and time. Perhaps this idea "is still right, but we're not solving the equations correctly," suggests Carroll. "

Jeff,

In accordance with the Theory of Infinite Hierarchical Nesting of Matter (my Essay), nuons are similar at the level of star to the white dwarfs, and nucleons to neutron stars and magnetar. Nuons are the result of evolution of cosmic substance under action of strong gravitation at the level of elementary particles. In Standard Model there is muons that almost the same as nuons. But the difference is their origin: muons are born in decays of pions and strong interactions of particles and unstable or have charge and magnetic moment. But the nuons are stable, they are result of natural evolution of matter and have no charge. In the absence of charge it is difficult to detect them. At LHC or similar collider we see muons. To check the idea of nuons: they are the supposed reason of dark matter, of redshift of remote galaxies, of microwave background, of attenuation of light spectra of supernova star and so on.

Jeff,

I really enjoyed your essay! Certainly if we find "dark energy" to be the dominant effect, it is more natural to "correct a repulsive force at small scales" than to "correct an attractive force at large scales," and the historical fact that we discovered "dark energy" relatively late should not deter us from this. However, I have a couple of questions.

1. Your 5th foundational question on page 2 involves the idea of curvature going to zero as matter content goes to zero, which is indeed a convincing point. However, I don't understand how repulsive gravity with a negative "cosmological constant" achieves this any more than attractive gravity with a positive "cosmological constant;" it seems that the difference is between positive curvature and negative curvature.

2. One argument for attractive gravity is based on the idea that gravity ought to be a "local effect." In other words, it is harder to think of objects at great distances "exerting greater and greater forces on each other" than to think of gravity as a local attractive "force" that simply dies out with distance and is overwhelmed by dark energy, whatever it is. What is your view on this?

3. Does dark matter factor into this in any obvious way?

If you want to know more about the motivation for these questions, you might look at my essay

On the Foundational Assumptions of Modern Physics

Basically, I am interested in the reasons for scale-dependence of the various interactions. Take care,

Excellent. We give very different proofs of very similar things.

(This is a reposed reply from my blog).

I turned from maths to ontological construction testing for the reason you give. Ken Wharton also exposes our foolhardy reliance on maths.

You might test this model; The axial anisotropic CMB flow is a scaled up version of a quasar jet. The CMB anisotropy itself has been resolved by computer into a helix, which precisely matches the quasar model, as the outflow jets from AGN's.

I have shown that AGN's are part of a galactic recycling process, re-ionizing all the dead stars and planetary matter to re-start the process with an open spiral on a perpendicuar axis. The common 'Kinetic decoupling' (perpedicular halo rotation) is thereby also finally explained along with other effects. Take a look at Centurus A (NASA HST) for a scale model of the universe.

Expansion is thus not accelerating but mainly reducing, except from the other end of the axis to the 'great attractor' (nonsense of course) in the direction of Leo. I've determined galaxies recycle every ~10-12Gyrs (a massive quasar peak is at z=1.7) so our 2nd iteration of the Milky Way is in middle age. A better analysis of the CMB anisotropy might constrain the same factor for our universe. (There may then be infinitely many numerically as well as temporally). If you're interested I'll link you to a past paper (new one in review).

Last technical point; I've found algerbaic vector apace cannot model motion as it's based on geometry where motion is an invalid concept, but I do know that to get a 'plus' sign hit; ampersand hash 43 semicolon. Like this; +

You'll have to allow for the fact that the ontological construction termed the 'Discrete Field' model has continued to come on by leaps and bounds over the last year. The resolutions of anomalies are like a flood from a breached dyke. This means the papers are far from up to date. (The latest ones are currently either in review or accepted but not yet published).

Hi Jeff,

In your sketch you say that the repulsive Cosmological term makes no mathematical sense. It's kind of funny, I look at the Cosmological term differently. In my view, anything that doesn't make sense is treated as an intrinsic characteristic. Dark energy is said to be the explanation of why the universe is expanding at an accelerating rate.

"The only way I know to do this is to invert the equation so that instead of solid "particles" moving within a void, the stress energy tensor describes waves moving within a solid. "

A solid is something that I can whack with a hammer. I don't think a solid is the right characteristic for empty space.

Technically it would be closer to a perfect fluid but that too has different connotations to different people. When people hear "fluid" they think of a water, but if I were to state that it was an elastic medium then they might think of rubber. A good qualitative description is difficult to give someone, so I just assume the best is to think of inverting the concept of what a particle is "made of" and what empty space is made of. What it would come down to is that if the hammer were to be made of waves, it apparently could normally only hit other waves.

If I am talking about aether waves and you are talking about a fluid, then perhaps we can meet in the middle and talk about waves of a fluid medium. I approached the problem by defining a set of waves that obey,

The largest possible wavelength is the size of the universe, which yields the smallest possible frequency; the smallest size is the Planck length, which yields the largest possible frequency. These waves can be energized as a particle or just a photon or photons. Or these waves can be un-energized, have no energy, and just be the background of space(-time).

I treated gravity as an image of energy. Energy, and components of the stress energy tensor, are excitations of aether waves (or fluid medium waves?). Gravity is an image that is produced by mass and energy. Gravity manifests as acceleration fields; acceleration fields are frequency shifts at each frequency. This produces time dilation.

Very interesting to see your essay.

Perhaps all of us are convinced that: the choice of yourself is right!That of course is reasonable.

So may be we should work together to let's the consider clearly defined for the basis foundations theoretical as the most challenging with intellectual of all of us.

Why we do not try to start with a real challenge is very close and are the focus of interest of the human science: it is a matter of mass and grain Higg boson of the standard model.

Knowledge and belief reasoning of you will to express an opinion on this matter:

You have think that: the Mass is the expression of the impact force to material - so no impact force, we do not feel the Higg boson - similar to the case of no weight outside the Earth's atmosphere.

Does there need to be a particle with mass for everything have volume? If so, then why the mass of everything change when moving from the Earth to the Moon? Higg boson is lighter by the Moon's gravity is weaker than of Earth?

The LHC particle accelerator used to "Smashed" until "Ejected" Higg boson, but why only when the "Smashed" can see it,and when off then not see it ?

Can be "locked" Higg particles? so when "released" if we do not force to it by any the Force, how to know that it is "out" or not?

You are should be boldly to give a definition of weight that you think is right for us to enjoy, or oppose my opinion.

Because in the process of research, the value of "failure" or "success" is the similar with science. The purpose of a correct theory be must is without any a wrong point ?

Glad to see from you comments soon,because still have too many of the same problems.

You say,

"Although the possibility of this error raises more questions than can possibly be answered in an essay, we maintain that little progress can be made until it is understood that General Relativity does not trump its own foundations."

I'm not sure about your meaning when you say that GR does not trump its own foundations -- foundations referring to "space-time?"

My essay discusses gravity but with emphasis on empirical evidence.

Hi James,

My meaning concerning foundations involves understanding the Einstein field equations through unimodular gravity. This idea, originally proposed by Einstein, is thought to be equivalent to GR, but views the cosmological constant as a constant of integration. It would appear that despite this, the ramifications have never been considered if one does this before defining the Einstein tensor as the stress energy tensor of matter. The derivation of GR requires curvature to go to zero (R_{uv}=0)with no matter or energy present, but the presence of a cosmological constant means that we must ignore this requirement. Using a unimodular approach, and prior to defining the Einstein tensor, this requirement can still be enforced and end up with a constant of integration in the equations. It would seem that the value of this constant is large but would appear small to us due to the simultaneous change in our understanding of the Einstein tensor. This change should pass down through the weak field equations, but the main way we would notice is that gravity would appear to become repulsive after a certain radius.

Jeff,

For this contest, I decided to go through and comment on essays of interest and see what responses I got to my own essay. There are over 250 entries, so I narrowed down my evaluations. For only those who responded, I decided to reread and provide my evaluations before time expired, not making it a popularity contest but keeping in mind that I entered for an exchange of interesting ideas, whether I agree or not. Some concepts are superior and more persuasively supported.

Jeff,

This is in response to your post on my essay site regarding my new zero's relation to the stress energy tensor Guv. You said "Where I see this relating to your concept is that while a stress energy tensor for Guv may become zero or 'nothing', if the two tensors of the right half become equal, the sum may become zero but that certainly does not imply it is "empty". This would very much seem to fit the full void of 'sunya'."

I see it the same way. Space may be empty of matter, but that doesn't necessarily mean nothing is there. My new zero makes explicit the possibility of something potentially being there.

After studying about 250 essays in this contest, I realize now, how can I assess the level of each submitted work. Accordingly, I rated some essays, including yours.

Cood luck.

If you do not understand why your rating dropped down. As I found ratings in the contest are calculated in the next way. Suppose your rating is and was the quantity of people which gave you ratings. Then you have of points. After it anyone give you of points so you have of points and is the common quantity of the people which gave you ratings. At the same time you will have of points. From here, if you want to be R2 > R1 there must be: or or In other words if you want to increase rating of anyone you must give him more points then the participant`s rating was at the moment you rated him. From here it is seen that in the contest are special rules for ratings. And from here there are misunderstanding of some participants what is happened with their ratings. Moreover since community ratings are hided some participants do not sure how increase ratings of others and gives them maximum 10 points. But in the case the scale from 1 to 10 of points do not work, and some essays are overestimated and some essays are drop down. In my opinion it is a bad problem with this Contest rating process. I hope the FQXI community will change the rating process.

Mr. Baugher,

very interesting and insightful essay. I am especially intrigued by this explanation you posted a few days ago and its conclusion:

" The derivation of GR requires curvature to go to zero (Ruv=0)with no matter or energy present, but the presence of a cosmological constant means that we must ignore this requirement. Using a unimodular approach, and prior to defining the Einstein tensor, this requirement can still be enforced and end up with a constant of integration in the equations. It would seem that the value of this constant is large but would appear small to us due to the simultaneous change in our understanding of the Einstein tensor. This change should pass down through the weak field equations, but the main way we would notice is that gravity would appear to become repulsive after a certain radius. "

Is there a way to ruffly estimate this radius? I have a visual approach to physics and understand GR as if it describes the curvature of a 3D hypersurface of a hypersphere, similar to a 2D surface of water in the ocean, with the troughs of the waves corresponding to attractive gravity and the crests, repulsive. To paraphrase the saying, my geometrical approach (in 4D) states that "what curves in must eventually curve out", which implies that the repulsive aspect of gravity manifests itself in intergalactic voids, thus explaining why they are empty. In this regard, I would very much appreciate your feedback on my essay ( fqxi.org/community/forum/topic/1547 )

I wish I could follow the technical aspect of your essay, but intuitively I feel that yours is one the most important essays in this contest.

Ms. Vasilyeva,

Thank you for the kind words on my essay. I have put a powerpoint up top to help explain it also which includes the equation you are asking about.

I have read your very interesting essay and will comment on your page so that others can chime in also.

Thanks

Jeff

The article is truly informative. However very recently there have been unexpected advances in understanding dark energy. In fact if the claim of the Egyptian Scientist M. S. El Naschie is correct, then there is no more a mystery regarding dark energy. El Naschie’s solution is disarmingly simple and was presented at two conferences which were almost entirely devoted to his work. The first was...

Einstein's equation mc square is a relativistic equation. When you regard the entire energy of the cosmos you are dealing with an extreme case. The point with an extreme case is that partial theories fail. For instance when you want to know the origin of all forces then you are in the realm of unification and therefore in the realm of quantum gravity. When you ask about quantum gravity then...

You do not need all this complication. That equation is just the end conclusion. The fault lies at the outset. He conflated existence and observation of existence, so c, as in observational light, is non-existent. Having deemed light reality to be reality, he then used c as time, which is a constant, because he calibrated distance in x=vt with the duration elapsed if light travelled it. In simple terms: he shifted the actual time differential which is in the receipt of light to existence, and substituted observational light with time.
