What ever happened to string theory?
Ultimately, baryonic string theory died for two reasons. First, it made predictions that disagreed with experiments. This new theory, called quantum chromodynamics, or QCD, today remains our theory of the strong nuclear force. And as for string theory, it mostly faded into the background.

How many string theorists are there?
There are currently five distinct string theories, which are related by dualities to M-theory. In addition, bosonic string theory also has many variants though it is not considered a valid candidate due to the tachyon and exclusion of fermions from the spectrum.
What is the major flaw with string theory right now?
The lack of even a single verified prediction in string theory, combined with its inability to even give the right answer for parameters whose value is already known, is an enormous drawback of this brilliant idea.
Has M-theory been proven?
Attempts to connect M-theory to experiment typically focus on compactifying its extra dimensions to construct candidate models of the four-dimensional world, although so far none has been verified to give rise to physics as observed in high-energy physics experiments.
What is M string theory?
M-theory is a theory in physics that unifies all consistent versions of superstring theory. According to Witten, M should stand for “magic”, “mystery” or “membrane” according to taste, and the true meaning of the title should be decided when a more fundamental formulation of the theory is known.
Who is the founder of string theory?
Italian theoretical physicist and string theorist. His 1968 dual resonance model of the strong interaction was the first string theory to be discovered, and thus he is regarded as a founder of the field. American mathematician and theoretical physicist at the Institute for Advanced Study in Princeton.
Why is Stephen Hawking so critical of string theory?
American theoretical physicist, professor at the University of Waterloo, and researcher at the Perimeter Institute for Physics. He is critical of string theory due to the reliance of the string theory vacuum problem on the anthropic principle, and objects to the dominance which string theory has over the search for a theory of everything.
What is the contribution of Russian theoretical physicist to string theory?
Russian theoretical physicist currently at Princeton University. He worked on the foundations of string theory in the early 1980’s, and in the 1990’s made seminal contributions to the study of dualities in string theory.
What is the theory of inflation in string theory?
The theory says that the early universe went through a phase of extreme expansion. The process magnified random blips in the quantum vacuum and converted them into the galaxies and other stuff around us. Theorists have had difficulty, though, showing how, or if, inflation works in string theory.
