What is an example of string theory?

The AdS/CFT correspondence is an example of a duality that relates string theory to a quantum field theory. If two theories are related by a duality, it means that one theory can be transformed in some way so that it ends up looking just like the other theory.

How does string theory explain multiverse?

Each compactification produces a different spacetime, meaning that string theory can realistically predict a multiverse populated by 10^500 different universes. If a theory makes so many different, contradictory predictions, they say, then almost any set of observations could be found to confirm it.

What does string theory say?

In simple terms, it does this by reimagining what reality is made of. Instead of treating subatomic particles as the fundamental building blacks of matter, string theory says that everything is made of unbelievably tiny strings, whose vibrations produce effects that we interpret as atoms, electrons and quarks.

What are the basics of string theory?

The Basics of String Theory. At its core, string theory uses a model of one-dimensional strings in place of the particles of quantum physics. These strings, the size of the Planck length (i.e. 10-35 m) vibrate at specific resonant frequencies.

Does string theory describe our universe?

String theory is a potential “theory of everything”, uniting all matter and forces in a single theoretical framework, which describes the fundamental level of the universe in terms of vibrating strings rather than particles.

Can We prove string theory?

No, string theory is a theory only. By definition, theories cannot be proven true, only proven not to be true. This is the case of Einstein’s theory of General Relativity. It is a theory which has stood up to a litany of tests, the results of which, it has correctly predicted, but it remains a theory.

Is the string theory correct?

If there is no supersymmetry at all energies, string theory must be wrong. For another, string theory, even in “only” 10 dimensions, doesn’t give you General Relativity as your theory of gravity, but rather a 10-dimensional Brans-Dicke theory of gravity.
