String theory is the idea that everything in the universe, every particle of light and matter, is comprised of miniscule vibrating strings. These strings are truly tiny, ...

String theory began over 50 years ago as a way to understand the strong nuclear force. Since then, it’s grown to become a theory of everything, capable of explaining the nature of every particle ...

In string theory, little loops of vibrating stringiness (in the theory, they are the fundamental object of reality) manifest as the different particles (electrons, quarks, neutrinos, etc.) and as ...

Striking evidence that string theory could be the sole viable “theory of everything” has emerged in a new theoretical study of particle scattering that was done by a trio of physicists in the US. By ...

String theory describes nature on extremely small size scales and high energies that are all but inaccessible to modern physics. The ideal experiment would provide direct evidence of these strings ...

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

In string theory, a paradigm shift could be imminent. In June, a team of string theorists published a conjecture which sounded revolutionary: String theory is said to be fundamentally incompatible ...

String theorists have used matrices to model the birth of the universe – the moment when three spatial dimensions broke free from the other six and expanded to produce the universe's 3D structure.

String Theory and Number Theory Have More in Common Than You Think, Maaaaaan A physicist and mathematician walk into a weird, mushed elliptical curve. Here's what they find.
