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 ...

In this video, we explore the relationship between string theory and quantum field theory (QFT). QFT is a mathematical ...

For the last 30 years of his life, Albert Einstein tried to come up with a Unified Field Theory, to combine the equations of Gravity and Electromagnetism. Unfortunately, he failed. In 1984, two Jewish ...

Natural physical networks are continuous, three-dimensional objects, like the small mathematical model displayed here.

Imagine a world unified by a single scientific principle, something that can explain life’s greatest mysteries, from the origin of space and time to gravity and smaller matters, like daydreams. Now ...

If extra dimensions of space exist, they must be smaller than about half the width of a human hair, according to new measurements of the strength of gravity at short distances. Researchers found that ...

It might sound like science fiction, but the three dimensions of space we are used to might not be the only ones out there. One theory of particle physics suggests there are in fact nine dimensions, ...

A simulation of the early universe using string theory may explain why space has three observable spatial dimensions instead of nine. The leading mathematical explanation of physics goes beyond modern ...

String theory, one of the most complex theories in the scientific community, may also be the "Theory of Everything" — a framework that explains everything in the universe. While still theoretical and ...
