is string theory true ?

Answer 1

There is not yet a complete string theory to be either true or false. There has not yet been a prediction from even a partial theory that can be tested. Even if the first ten tests fail, it would most likely mean there's something wrong in the details of a theory, not that there is no valid string theory. It's an extremely complex field. If Newton were at this stage of development, he would say I'm working on force and mass and acceleration and gravity. When I'm done, if I'm right, you'll be able to make calculations relating them.

Answer 2

i dont think so the basis of string theory is the vibration rate of the string its like a tone it has harmonics of that tone those harmonics are like the universes. a change in the harmonic frequency is why a particle can apear and disapeare.all visable matter in this universe has the same harmonic frequency and so it interacts with other things also having the same frequency matter with a different frequency is not observable herebut can be detected by a harminic universe.there may be a dead string universe but that is more a principle of time if say all strings were to stop in mid vibration. this would follow relativity if the strings of a photon expireance zero time at light speed its vibration stops. lets say this universe vibrates its strings at 100 cycles per second a string that was half as long could vibrate in a harmonic of the first string you would then have three universes the first string and the two half stirngs. the two half strings could readily observe each other and inter act. the first larger string may not be abily to observe the other two but could effect them. now the speed of light is constant in the long string universe it is probably also constant in the other two but may be twice as fast when compared to the fist or only going half as far in the same time. but light speed may be the same in all universes if time stops for the photon i cant say if a photon string can be given a new harmonic or not.but at zero time would be a good place to make the change i think.

Answer 3

String theory is a way of incorporating gravity into the Standard Model, our current best mathematical explanation of how the universe works.

One of the chief complains physicists have with string theory is that the string theorists cannot come up with any way to test it. If something cannot be tested, it does not matter whether it is true or not.

Answer 4

I believe it to be correct, or rather "M-theory" which is a more general case of supersymmetric string theory.

The reasoning is that the math is so beautiful and fundamental that it is likely true.

Answer 5

It has not made any satisfactory testable predictions yet. On that basis the answer has to be no, it is purely speculative. It is certainly not admissable as part of the canon of science at present.

It may become possible to test it later this year.

Answer 6

no theory is absolutely true.they can only be relatively fit to the real world.Reletivity,for example.
