String theory is perhaps the most high-profile candidate for what physicists call a theory of everything – a single ...

String theory has long been presented as physicists' best candidate for describing the fundamental nature of the Universe. Yet, at the beginning of the 21st century, it became apparent that most ...

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 ...

Since the 1980s, string theory has emerged as the leading candidate for achieving every physicist’s dream: reconciling general relativity with quantum mechanics and thereby finding a tidy ...

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

Scientists are on the trail of a mysterious five-particle structure that could challenge one of the biggest theories in physics: string theory. This rare particle—never seen before and predicted ...

Physicists have proposed a new model of space-time that may provide the 'first observational evidence supporting string theory,' a new preprint suggests.

The problem with string theory, according to some physicists, is that it makes too many universes. It predicts not one but some 10 500 versions of spacetime, each with their own laws of physics ...

String theory is often suggested as a possible solution for this universal explanation, but it is very difficult to test.
