String theory suggests that vibrating strings that exist in 10 dimensions underpin the observable Universe. Although that basic premise is still very much in doubt — and as yet impossible to ...

At its most basic, string theory is the idea that the foundations of matter and energy are not particles, but one-dimensional strings that vibrate in varying patterns.

Scientists have long sought evidence to refute string theory, but a new test seeks to disprove key aspects with help from the Large Hadron Collider.

The idea of String Theory is that our Universe came from a higher-dimensional, more symmetric, more complex state with an enormous number of degrees of freedom. In order for String Theory to be ...

Using machine learning, string theorists are finally showing how microscopic configurations of extra dimensions translate into sets of elementary particles—though not yet those of our universe.

In many regards, string theory is the best contender for a quantum theory of gravitation, which just happens to unify at the highest-energy scales.

After all, since string theory aims to unify the basic interactions, its success in spawning new empirical applications or technologies is quite irrelevant. However, renouncing the value of ...

The five main string-theory candidates may all just be pieces of a larger, cohesive whole — and M-theory could bring them together.
