Is string theory finished or proved incorrect in theory?

Answer 1

It has been proven a hoax

Answer 2

It is neither finished nor proved. Until String/M theory is tested (and not disproved), it is, at best, some elegant mathematics, which some physicists claim are more philosophy than theory.

Even as we speak, the Large Hadron Collider in Cern, Switzerland, is slated to do some experiments to prove or disprove some aspects of String/M theory. There are also some cosmological observational experiments (e.g., on the nature of gravity) that have been proposed to examine String/M theory. Check this out:

"Research

Physicists hope to use the collider to enhance their ability to answer the following questions:

Is the popular Higgs mechanism for generating elementary particle masses in the Standard Model violated? If not, how many Higgs bosons are there, and what are their masses? [2]

Will the more precise measurements of the masses of baryons continue to be mutually consistent within the Standard Model?

Do particles have supersymmetric ("SUSY") partners?

Why are there violations of the symmetry between matter and antimatter?

Are there extra dimensions, as predicted by various models inspired by string theory, and can we "see" them?

What is the nature of the 96% of the universe's mass which is unaccounted for by current astronomical observations?

Why is gravity so many orders of magnitude weaker than the other three fundamental forces? " [See source.]

"The Elegant Universe" is an excellent source for learning more about Strings and the problems we have with testing them. [See source.] But to your question, string theory is not dead; otherwise, the very expensive LHC would not be used for testing it.

Answer 3

The theory has a very interesting concept >The ideas may lead to the truth about the nature of light which In Creation of the Universe was the first item created.
However there is a theoremthat says not everything needs proof.
Nor that we need to know everything.
And most humans dont care to know everything.

Answer 4

string theory is neither

currently, no test can be done to prove it one way or the other which makes some physicists say that it really isnt even a theory.

by the same token, string theory isnt really finished because scientists are working nonstop to find a way to test it

Answer 5

String theory is neither proved incorrect nor finished. It is still under consideration & continuous effort to satisfy other existing theories. Which one day may lead to its prevelance. The thory you can see at:

Answer 6

string theory is not completely finished yet.......so cant say

Answer 7

neither... they are till working on it
