The ToE: Unification or Replacement?

In summary: informally it's as if you took a single electron out of a hydrogen atom and moved it around...the electron still has the same energy, but it is no longer part of the hydrogen atom.

When people talk about the Theory of Everything, they usually think of the theories that are trying to unify GR and QM (such as SMT and LQG), since this is what the majority of Theoretical Physicists are working toward, unification. However, I've just begun reading Smolin's Three Roads to Quantum Gravity, and have been wondering: What do you all think about replacing General Relativity and Quantum Mechanics with theories that are more compatible?

When I first heard that there were actually people working towards this, I thought they must just be some crackpots who were trying to be unique...but now I realize that there are actually quite a few very good scientists working on this problem.

So, what do you think? Can GR and QM be replaced with better theories? Could that turn out to be the Theory of Everything? Also, exactly what theories/hypotheses do you know of that have been put forward as possible replacements?

Any response is appreciated. :smile:

Personally, I think that there is too much in GR, and QM, that does actually work now, hence replacing isn't what I would think would be done, enhancing or extraoplating perhaps, but I doubt that anything needs replace the parts of the currently "known theories" that DO work.

Perhaps a "New theory" that simply is new in it's completeness, still incorporating GR and QM, but brought out under a better, more complete, title, hence ToE.

I don't know enough about QM and GR to say if they can be replaced or not, however I do think that everything can put in a much easier way (although Einstein did a very nice job on GR), so maybe they can't be replaced but just "re-defined".

I agree with Astrophysics. Einstein did a nice job on GR and if scientists just took it out of context, it really wouldn't be worth the wasted effort.

I do think there is an alternative that isn't being tried. Mate the Standard Model to the loops of loop quantum gravity, and work out the physics of that. It would become a new branch of theoretical physics, just as lattice quantum theory is. Like lattice theory, it could be done "non-perturbatively" which means it could handle large energy interactions. Like string theory it would be free of the quantum infinities tha come with classical geometry.

Draw a circle on this practicum, go to the next thread and understand the energy values of building in the Monte Carlo.

We have discussed these issue before. Understanding .Greg Egan's site and the loops inside, was most helpful.

I am afraid you didn't understand me Sol. It isn't about geometry, and the loops in LQG aren't geometric loops, they'r quantized, with eigenvalues. And the questions are about quantum dynamics, and states in Hilbert (rather Fock) space, and operators thereon. The point of background free dynamics is that the particle states and the loop states wil combine.

I will look into this deeper and research for better clarity. Any points that you could expand on here to help orientate?

I would point out that the descriptions I gave in the post above was speaking to the idea of energy and how it is used to describe movement of particle natures(Yours as well). If such energy determinations can be garnered fron each particle state, then how would we have described them but by using complex ways in which to see this.

Remove the coordinated system of Greg Egan's site and you are left with the loop and its energy differences along the length of the loop. Remove the distinct line of the practicum and we are left witha energy value in a loop. Remove the idea of the triangulated shapes of the monte carlo method and see how the energy plot is being used to describe the construction?(hope that made sense)

Ths has been the jest of seeing the envelope in place of matter distinctions. It allows us, if this can be done(https://www.physicsforums.com/showthread.php?s=&goto=lastpost&forumid=66 ) The undertanding that energy values describe the movement in the envelope and represents the aspect of the dimensional significance of the early universe, compared to condensation in planetary formations.

Symmetry is directly related to dimenison and so is gravity?

Energy values speak directly to the nature of curvature, and is the basis of energy determinations(strings) and the applicable means in which we are attempting to describe its values? Seeing Loop's is a little more difficult for me, but I have placed it in the determinations as language development option:)

Sorry for misconstruing:)

I'm inclined to agree with you, Parsons, but I still find it interesting that some people have actually taken it upon themselves to defy (probably the wrong word, as GR and QM are not royal decrees or anything) the two most established theories of modern Theoretical Physics.

But would this solve the contraversy between GR and QM? The loops of LQG are background-independent, so that is taken care of, but how does one go about "mating" the Standard Model with the background-independence of loops to make a theory?

Darned good question. I was only suggesting a direction, not proposing a method :)

Some indication would be to look at the way they "put the standard model on the lattice" (I love physicists' terminology, the lattice, not a lattice). This is a twenty year old technology, so there should be some very experienced folks out there. The difference would be that the lattice does not participate in the physics any more than Minkowski spacetime does in the regular version. (We-e-ll the sides of the cells are momenta, but the spacing is unchanged over the physics, so they can meaningfully take it to zero after all is said and done)

How to cover the background freedom? I think of it (Kaku style) as tensoring the spacetime states with the particle states. Ashtekar & Co. show that their state object CYL, basically the linear functions on the loop network, can be fed into the Fock space with the particle states (they only do scalar "proof of principle" particles). But they need more work on this basic math.

Interesting. I suppose this is a creditable approach (even if the actual method is still unknown...heck, Newton invented a whole new branch of mathematics for the Classical Mechanics).

Dear Mentat,

I too have read Smolins "3 Roads to Quatume Gravity" and "Life of the Cosmos" in last year.
More recently hive just finished Earnest Sternglasts "Before the Big Bang."

Sternglasts thing is that it ALL is based on electron-positron pairs and their subsequent
roatation and splittings. The following link is the latest confirmation attesting to the Lematrie
primeval electron-positron atom as proposed in Sternglasts book.

http://www.newscientist.com/news/news.jsp?id=ns99994214

How I understand LQG, Sting, QM and GM via my recent readings is that Bohr and Hesignberg
belived only in a mathematical approach to knowing the nature of Universe whereas Broglie
and Einstein belived there must also be a causal based geometric visual for that understanding.

This is where I've extrapolated out from Bucky Fullers Synergetics what i feel is a more complete and
unifying understadning of the nature of Universe using Euclidean and quasi-Euclidean polyhedra. By
beginning at the top --i.e. most generalized and comprehesive nature of the Universe-- and working towards the bottom --i.e. the more particular/special-case-- i think I've furtherd Fullers hopes of indentifying cosmic particles via geometry.

The key here lies the realtionship of and between fermions and bosons ergo of and between 4 and 5-fold polyhedral geometries.

Im sorry i do not have a decent website with my set of others graphics to visualy explain the details.

Ponder this:

There is someone alive at this moment who possesses knowledge on how physics can be patched up. The theory is not highly abstract, in fact it is winding the clock back to the relatively simple days of the past. This person has a degree in mathematics, but works in a lowly job, spending all his available time developing the theory. He has accumulated a wealth of results, but knows that the establishment will find it very hard to accept them. But he wonders whether it is even appropriate to publish the results, and prefers to use it to for the sake of personal development. After all, anyone who is truly interested in personal development will uncover the same knowledge in one form or another. Besides, why should knowledge be handed out openly to a culture that will make a dog's dinner of it?

I wonder how many people there are like this living on the planet at this moment?

I wish Einstein were around so I could ask him...

Why isn't distance a component of Energy? He includes mass and speed, but no distance. Isn't Energy a result of a balancing act of these three forces?
 
  • #17
I agree 100% about distance, so you explain what you mean, and see if you can explain it better than I can. If we are anywhere near the same idea, maybe we can formulate a plan.
 
  • #18
Because I'm speaking intuitively and not as a result of my knowledge of math and physics this may be difficult. However, as I see it all energy systems (atoms, planets, solar systems, galaxies, universe, etc.) are composed of rotating (speed component) matter (mass component). The resulting size (distance) of the system depends on the ratio of rotational speed to its own mass.

Have to go. I'll try and come up with something a little more descriptive of my thoughts and post it later.
 
  • #19
How would rotating planets and galaxies affect the energy of atoms and elements? And yet, atoms and elements look like rotaing galaxies and planets, so what if what you are intuitively seeing happens at a much smaller scale?

Here is what I see. Start in the pre-existence, before time. All the matter in universe is a sea surrounded by the concept of nothingness. The concept of nothingness does not contain the concept of space. All the matter is being pressed together because there is no space around it; only nothingness.

What does matter look like? Does it look like a hard rock? A hard rock is difficult to pull apart. But matter looks like water. It is easy to pull apart and hard to compress. Matter is all in one place because it is being pressed in by nothingness. There is no space in nothingness. This has the appearance of an ocean held in place by gravity, but the force is not the weight of the ocean, but the fact that there is no space surrounding it, and the concept of nothingness is keeping it in. There is nowhere for it to go.

The amount of force that it takes to pull matter apart is the weak force. So take a drop of matter and force it into the nothingness. Here is where distance comes in. The farther you force the drop of matter into the nothingness, the stronger the nothingness (vacuum) resists and wants to snap the piece of matter back to the ocean of matter.

Imagine a hollow tube between the drop of matter and the surface of the ocean. This hollow tube does contain the concept of space. How do we describe a string? It is a thick hollow tube like a garden hose, with walls that have no thickness. We have an ocean of matter and one drop of matter. They are connected by a fat hollow tube that has walls with no thickness. On each end of the tube is a piece of matter. In this case, on one end is all the matter in the universe, and on the other end is one drop of matter. A kind of hollow tube connects them, which is nothingness being expanded into. A string is said to be a two-dimensional tube with a tension that is the strong force.

Now we have created a string. It is matter expanding into nothingness. Each piece of matter has size but each is considered a dimensionless point. They are connected by a mainfold that is like a fat hollow tube, which contains the concept of space and distance, bored into the concept of nothingness by the two points of matter. I'll continue later.

John, you ask what matter looks like pre-big bang. If Einstein is correct, then energy is transmutable into mass and speed (and I would add distance). Therefore, pre-big bang there is no matter, only energy. Now, as to what that energy looks like, your guess is as good as mine. At this point in our (human) experience, I don’t think we have enough knowledge to accurately model pure energy.

MASS: Creates gravity-wells that attract other matter. A key point is that matter is pulled in along the “shape” of the gravity-well that is funnel-like or circular in pattern. As the mass increases, so does the pull of its gravity or the size of its gravitational well. The Big Bang created the most massive gravity-well, and the black holes at the center of galaxies are current examples of “stable” gravity-well systems. In my opinion, no system is entirely stable because gravity wells extend into infinity. They only seem stable relative to our (human) time reference or experience.

SPEED: Created by the Big Bang and also by the gravity-wells of massive objects. The faster a mass moves relative to the center of the gravity-well, the longer the distance to that center is maintained. In fact, the speed of a moving mass can increase the distance relative to the gravity-well until equilibrium is achieved. Therefore…

DISTANCE: is the sand (using an hourglass analogy) that separates the inevitable reunification of all matter (in one glass) subject to its speed (in the other glass). The greater the distance, the slower the speed necessary to maintain a distance or stable system. With a shorter distance, greater speed is necessary to stave off the “fall” toward the center.

Mass pulls other masses toward itself. Speed of moving matter is the force that maintains distance or props up the existence of space. The distance of masses at certain speeds defines how long that system will continue to exist before it collapses upon itself. Atoms were the first stable systems to form and became the building blocks upon which all subsequent matter grew and will be the last to go.

Speed and distance are the only forces that slow the collapse of matter upon itself.

As you can see, I’m still not communicating my thoughts very clearly. I’ll keep widdling away at them until I can accurately express myself and hpefully come up with a more thoughtful post.

We only see things in part. Your ideas concerning distance are about system decay or entropy, the very same thing my ideas concerning distance are about.

But as you write your ideas, there is an idea that seems contradictory: you have to say that speed and energy and entropy is lower as distance gets greater. What you would probably like to say is that it gets stronger with greater distance. Then you would say speed and energy and entropy increase as distance increases. But gravity gets weaker and everything seems to go slower farther out. So what if the real attraction is not gravity?

Energy is matter in motion, E= mc2, energy is mass x velocity. That easily describes repulsive forces, like a moving bullet, or a car. It hits something and knocks it away. What about attractive forces? What the heck are they? What is the strong force? Where does it come from? How does any attractive force happen?

Go to the original universe before time began. There is a singularity. Surrounding that single point is nothingness. If you expand the matter, it expands into nothingness. The idea of “nothingness” does not even contain the concept of space. Points of space are expanding into nothingness that does not even contain the concept of space, so therefore, nothingness resists being expanded into. It pushes back. Two points that are separated want to come back together. The nothingness "sucks" them back together. Here is a case where attractive force increases with distance.

Now blast individual points of space into nothingness. Near the blast, the points are a certain distance apart. As they spread out, the points of space get farther apart. Think of space itself being created. The points are expanding into nothingness.

Light is traveling from one point to the next. A photon collides with a point of space, knocking it across to the next point. Think of light traveling though space as a series of collisions between points of space. There is an attractive force between points, so when a point is dislodged, it will be pulled directly into the next point.

All the points spread out from the center, from the Big Bang. Nothingness is what the universe is expanding against, not gravity. While they have been expanding, they have been creating space. Space is gradually getting bigger, but it doesn’t appear to be getting bigger because light always travels from one point to the next in the same amount of time, however, when the points get so far apart light fails to make it all the way from one point to the next, the moving point stops, creating a point that has entropied. The entropied point falls into the space between points, and the point that has entropied falls all the way back to the center of the universe, falling through the spaces between points like falling through the cracks.

The points in molecules are also traveling on ever-expanding strings. When space is old and stretched too thin, the point particles begin to fail to make it to the next point, and molecules entropy. Entropied molecules clump together, get dense, and fall back to the center of the universe through black holes, where they explode back apart when they hit incoming matter from the other side, for a continuous Big Bang, continually creating the universe in layers.

You know, If you really think about it, there are soo MANY paths you can take towards ANYTHING. You know, GR is an AMAZING theory, but then again, it has it's flaws. Same with every theory in the physics spectrum. I think that it is very probable that there are other, unexplored theories out there. Sometimes I say,"WOW, these theories can predict this and this and this. It's the perfect theory. But why can't it predict this?" And it makes you wonder if we are just beating a dead horse. So yes, i think it is a great idea that people are taking action towards the problem, but i think it's best if we all work hard on all the theories, and not to give up on any.

Light fails to get from one point to the next - when space has expanded too far?

Does this mean there exists a 'breaking point' for the universe, a 'time' when the equilibrium between mass and expansion snaps?

Is that possible?

If the structure of space-time (according to string theory) is composed of energy strings connected in every available dimension, are you saying there'll come a point there the expansion breaks this structure apart? Would not even one single failure of the fundamental structure create a chain-reaction collapse of the universe anyway? Every machine is only as good as it's smallest component. Even the 'death' of one string connection should have devastating effects on the whole.

As for the expansion causing molecules to entropy ... perhaps at the 'time' in the universe's life when it is stretched too thin to support itself there won't be any complex molecular chains still in existence. Despite the obvious creation of complexity going on around us, the universe has, quite possibly, a tendency to self-destruct as it consumes all the available energy, hurtling toward it's heat death. Also, just because the universe is expanding, does this mean every single point within it is expanding away from each other? And if this is the case, would we be able to discern that the universe was expanding at all if we and every reference point around us are all expanding at the same rate? The apparent 'size' of the universe would, in our terms, remain fixed.

I canna change tha law of physics, Cap'n ...

Proton deterioration would have to be when a proton gradually breaks down. And we know that molecules entropy, and become a densely packed mass, like a neutron star. The motion in the molecule keeps it expanded.

I theorize protons are made of “points” and that electrons travel on the surface of the proton from point to point, expanding the proton like a balloon. This would make a proton...a brane. If protons can gradually decay, that would mean they lose some of their points, like losing teeth, and when too many points are lost, electrons, which travel on the surface of protons have hard time jumping across the gaps, so they stop, and the molecule starts to entropy, ending up as a tight little bundle of matter, like a neutron star.

I theorize that space has “points” and light travels from point to point. The points are expanding on a constant journey outward. The area of space we are in will eventually be too expanded, and light will have trouble going from point to point. At that time there will be a catastrophic collapse of space itself and all the points of matter that make up space will come together like a neutron star and all of this matter will fall through the cracks between the points of space to the center of the universe. They will collide with incoming matter and start over with another bounce outward.

The beauty of the system is that it entropies before it stops moving outward. It falls back through the cracks, along with all the entropied molecules, so there is never a big crunch.
 

1. What does "The ToE" stand for?

"The ToE" stands for "Theory of Everything." It is a theoretical framework that seeks to unify all the fundamental forces and laws of nature into a single, comprehensive theory.

2. What is the significance of unifying all the fundamental forces and laws of nature?

Unifying the fundamental forces and laws of nature would provide a more complete understanding of the physical world and potentially allow for the prediction of new phenomena. It would also bridge the gap between general relativity (which describes gravity) and quantum mechanics (which describes the other three fundamental forces).

3. Is "The ToE" meant to replace existing theories?

It is not necessarily meant to replace existing theories, but rather to provide a more comprehensive and fundamental understanding of the physical world. It would build upon and incorporate the principles of existing theories, such as general relativity and quantum mechanics.

4. Has "The ToE" been proven or established?

As of now, "The ToE" remains a theoretical framework and has not been fully proven or established. Scientists are still actively researching and developing various approaches to achieve a unified theory.

5. What are some potential challenges in developing a unified theory?

There are several challenges in developing a unified theory, including the complexity of the mathematical equations involved, the difficulty in reconciling the principles of general relativity and quantum mechanics, and the limitations of current technology and experiments to test the theory.
