Scientists seeking the secrets of the universe would like to make a model that shows how all of nature’s forces and particles fit together. It would be nice to do it with Legos. But perhaps a better ...

String theory is a purported theory of everything that physicists hope will one day explain … everything. All the forces, all the particles, all the constants, all the things under a single ...

Moduli spaces form the mathematical framework for categorising the diverse solutions characteristic of string theory, providing a systematic means to parameterise the various vacuum configurations ...

In an unprecedented step, researchers crafted a detailed model compatible with the universe’s accelerated expansion.

String theory proposes that the fundamental constituents of the universe are one-dimensional “strings” rather than point-like particles. What we perceive as particles are actually vibrations in loops ...

Some see string theory as the one great hope for a theory of everything. Some see string theory as the one great hope for a theory of everything – that it will unite quantum mechanics and gravity and ...

Jason Lotay explains how mathematicians studying special geometries are collaborating with physicists to explore M-theory, an 11-dimensional description of the world that unifies the various string ...

Why strings? What are they made of? How did physicists even come up with this bizarre idea? And what’s all this nonsense of extra dimensions? PBS Space Time is available to stream on pbs.org and the ...
