    There’s this idea that beauty is a powerful guide to truth in the mathematics of physical theory. String theory is certainly beautiful in the eyes of many physicists. Beautiful enough to pursue even if it’s wrong?

    Hermann Weyl once said, “If I have to choose between beauty and truth, I choose beauty.” It was in reaction to a rebuke by Einstein. Weyl had tried to explain electromagnetism by imposing on Einstein’s general theory of relativity very first gauge symmetry, Weyl invariance. Einstein pointed out it the proposal led to some absurd results, and so the idea went down in flames. It just couldn’t be true, despite the elegance of the math. But sometimes it can be hard to let go of the sense that a beautiful theory must be right. Could this also be the case with string theory?

    proteins are made from amino acids. DNA is made from sugars and nucleotides, which are bases.

      It seems that string theory is exactly the same as Congress. Instead of scrapping what doesn't work and starting over, just keep adding, redefining, twisting facts and figures, spinning the truth until you have something that can totally baffle everyone, but you can claim as truth.

                          Logically correct: Theory, by definition. inherently admits that it does not have all the facts down. They are all wrong and yet some are still of some usable value anyway. That said, I often wonder if one could replace the need for extra dimensions in such theories with high energy realms* in the energy flow such that there is such a speed difference in its interior that it is no longer able to relate NORMALLY with what is outside that intense field state. That is, gravity is expressable through such intense areas, yet electromagnetic fields are not able to propagate in any normal form out of them. One might imagine one possible form as being like a minuscule wormhole. Its possibility comes down to the logic that things are inherently already moving faster than the speed of light to each other. Such as two electrons moving in opposite directions. So exceeding light speed is not impossible IF the realms doing it do not interact with each other directly. That, of course, would force them into exploding from the inability of the internal energy that makes them up from flowing in the way that makes them a stable particle.

                          ^ such extreme energy states are the basic requirement for the formation of stable arrangements we call particles that are notable also able to propagate as waves that I suspect are in an entangled state that lets them interact with others as a particle by effectively having their entangled waveform become a unified response without a speed limit across any distance its waveform has come to be at due to its propagating up to that time.

                                    Bullshit video. Quarks are the smallest particles we know of, but hen they have to be made up of something infinetesimally small, or else they couldn't exist. Even stone, neutrons and electronic one as they are made up, must contain something between their particles, as nature abhors vacuum.

                                      String theory is wrong because there are no extra dimensions from the 4 known.
                                      dimensions that exist in subatomic scales is the same as the known 4 dimensions at very far distances .
                                      We can look very close to the event horizon of the universe and infer from data the same 4 dimensions as in our local solar system.
                                      This is correlated to looking in the opposite direction and only observing the same 4 dimensions.

                                          String theory is right. String theory is wrong. String theory is just that. A theory. In 10 more years it could be proved right. It could also be proved completely wrong.

                                            String theory is not wrong, but unverified.
                                            The critiques of string theory made in the following books, have yet to be rebutted:
                                            String theory makes a strong and sweeping prediction: corresponding to every known elementary particle that makes up the Standard Model of
                                            particle physics and the fundamental interactions, there exist a supersymmetric counterpart. To date, no supersymmetric particle has been
                                            found. String theory also predicts a scalar boson, called the graviton, that mediates gravitation. To date, the graviton has yet to be found.

                                              I think when we really understand gravity, a lot of things in theoretical physics is going to feel different. Right now I think high-energy and quantum physics is in a strange cul-de-sac created by physicists more enamored with beauty in mathematics than truth. Experimental results that direct the development of theories needs to be the benchmark, not extra tricks in math.

                                                                      Beauty is subjective and can delude you.

Even with relativity, there are frames of reference where all the relative view are coherent and make sense together (space-time interval vs local time, for example). Even in quantum mechanics, there is an independent reality (in fact, it's arguable more real and independent than our view of it is).
                                                                      When people say there is no 'objective truth'.. what they mean is 'there is no one way to interpret something'.. which is true - but not the same question. That's actually the problem with beauty.

The bes way to prove or disprove a theory is not testing its predictions, but its founding assumptions. Newtonian physics has many correct predictions, but if the speed of light is constant(Einstein), then Newtonian is ultimately wrong. If however the speed of light is not constant, then Relativity is wrong. Are there really more than 4 dimensions? If not then string theory must be wrong. I have found that math is much easier when the number of dimensions is a power of 2(based on hypercomplex numbers). 3D games are actually rendered in 4D not 3D as the math is much simpler. Why 10 or 11 dimensions and not 16? We could then use the sedenions to simplify the math.

                                                                              As far as I understand string theory... it can never be proven or disproven through experimentation. One could easily argue that a theoretical physicist is simply manipulating the numbers until they work out on paper.
                                                                              That being said, aren't there other fields with many more practical applications that there time would be better used? Even if we all decided that string theory was now a law, what good would it do. We lack the tech and knowledge do do anything with the information and likely always will. These strings are smaller that anything we could ever use to observe or manipulate them with so what's the point?

A graviton does not look like anything else in the pantheon of particles, but shows space/time to be a particle. thus strange. duality? well what is the opposite or anti-matter co-efficient of a graviton? Negative space/time? struggle struggle.

But if there are countless multiverses with different laws of Physics then something so super abstract like Mtheory makes more sense.
