Toes are the digits (fingers) of the foot of a tetrapod. Animal species such as cats that walk on their toes are described as being digitigrade. Humans, and other animals that walk on the soles of their feet, are described as being plantigrade; unguligrade animals are those that walk on hooves at the tips of their toes.
I am reading a hebrew translation of the popular book by Michio Kaku on HyperSpace.
It seems Superstring Theory will never be refuted since if it's a theory of everything then you need infinite energies since the universe is infinite, and we can never get a from finite machines infinite...

I been studying quantum field theory and standard model lately. I not see how a unified theory could fit between quantum field and special or general relativity. One being for big objects and the other for microscopic one. In fact, standard model not seem to be all proven. Many particles are not...
Given the state of current and recent TOE advances, (Ads/CFT, LQG, M-theory, Twistors...) in what framework do you believe a TOE will first appear?
I say first because I have a hunch that a breakthrough in one area will correspond to dualities in others. It seems to me that if a given theory...

I'm wondering if Quantum Gravity is expected to be a Theory Of Everything (TOE)? Can we expect that if we combine QFT with GR to get Quantum Gravity, will that be a TOE that explains GR and QFT?

Both Hawking and Dyson have said that Godel's incompleteness theorems prove that it is impossible for us to formulate an absolutely fundamental Theory of Everything.
Is that true? Do the theorems apply to the physical world as they apply to the realm of mathematics?

Hello everyone!
As an admirer of string theory, I have strong interest in the theories that purport to unify general relativity with quantum mechanics. In the case of string theory, the goal is to find a form of describe the force of gravity according to the principles of quantum mechanics, ie...
If superstring theory works, has no infinities, etc. Then what is wrong with it? It must describe some Universe unless there is a contradiction in it somewhere? If it predicts all particles and gravity what is missing from it? Is it not compatible with cosmology for instance?

Here is a question about the possible limitations of physics, specifically about whether a theory of everything can actually explain everything.

Is Our Mathematical Universe by Max Tegmark any good, as a work of popsci? Apparantly it's related to some TOE thing Tegmark's got, is that one actually something legitimate?
(Edit: Sorry if this isn't appropriate for this forum!)
Normally, we think about a grand unified theory (GUT) that unifies the standard model forces and particles into an overarching unified framework, as a pre-requisite to a theory of everything (TOE) which adds quantum gravity to a GUT.
But, developments of both beyond the Standard Model physics...
Have weak nuclear, strong nuclear, and electromagnetism all been unified? If so, is that the GUT? And is it that unifying those forces with gravity would lead to a TOE?
Thanks. I'm just getting a little confused.
I am hoping to get some guidance in this thread from those who have traveled the path before me. For the past couple of years I have been on a tear to educate myself in mathematical physics for a variety of reasons I won't bore you with here (some personal, some professional). In any case, to...

I wonder if TOE candidate theories (loop gravity, superstrings, twixtors, or <you-name-it>) predict from the first principles SM parameters (all, some of them, or some correlations like Koide formula)?
If they don't predict SM parameters, then the only option is "10**500 different universes...
Hi guys basically I'm in secondary school and my teacher started taling to me about the four forces in space which are tryin to be unified by TOE and the Grand unification theory. She said that at my level I don't need to know what they are and she said that she wouldn't go into them in depth...
Most if not all laws of physics are not mathematical, rather statements that define the way mathematical models must follow. They have been laid down by intuition and observation.
So how can something like string theory based on maths be expected to achieve a GUT or TOE if it does not know...
Hey.
I've heard from several physicists that in the next few years, physics might come to an end after completion of the theory of everything and that basically, there's not going to be anything new to research in physics.
What are your thoughts on the matter? Do you think such a theory is...
They irritate my feet and legs, the first thing i do when i get home is to take the off, i think toe rags were first worn to stop boots scuffing feet, that's where the derogative form (you are just a toe rag came from), may be it is just us westerners wear socks.
Another silly question here :)
What are some of the cosmological observations a TOE must agree with? (I'm making a list)

b) element ratios (Hydrogen, Helium,...)
c) bias toward 'matter' rather than 'antimatter'
d) CMB...

Well I've searched this forum and didnt see this topic before, so I was wondering what the general consensus is on the impact of Godel's theorem (if any) on a possible TOE?
I'm still wading through it all so just wanted some other opinions...
I was just wondering, I keep hearing different opinions on this, but how is the reputation of string theory now?
I speak to some mathematicians and they completely write it off, while I talk to other people and they say it's still in the works but looks promising.
Obviously it's not...
LQG is an attempt to quantize geometry
Noncommutative geometry is an attempt to express the SM geometrically, and is able to derive the SM Lagrangian and prediction of Higgs mass.
LQG is not a TOE since it does not include SM, only quantize gravity, and NCG is not a TOE since it does not...
Hello..
I read somewhere that Mathematics is an imperfect science...basically a science with ultimately unprovable assumptions.
Could that be the reason for the problem of squaring relativity & quantum mechanics?
Thanks for any and all responses.

Which branches of theoretical physics are the most likely to find a TOE?
I'm just trying to learn a little about this stuff, but my physics knowledge isn't too deep as I am only a first-year undergrad.
A nudge in the right direction would be appreciated!

What if TOE is "non-analytic"?
I mean, what if there is a set of TOE equations, but there is no way to derive all notions we want to derive (space, time, gravity, number of generations) from it analytically. And the only way to do it would be a huge numerical simulation?

This speculative effort may be only wishful thinking, but if mathematical [geometrical] objects can be represented by Lie [and other] Algebras and Groups as well as by Mathematical Games, then this may aid in the search for a GUT / TOE.
This effort is not rigorous, but a tenuous association...
One interesting notion that strikes me from time to time, like now, is that if String Theory [ M Theory] is correct or nearly so, the greatly anticipated theory of everything, or TOE, is not a theory of science and never can be. Rather, M theory stands as a philosophical proposition, and it...
Yes, this is for real. I want to settle a bet.
