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 ...

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 ...

It's one of the most brilliant, controversial and unproven ideas in all of physics: string theory. At the heart of string theory is the thread of an idea that's run through physics for centuries, that ...

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 solved ...

Researchers in Japan have developed what may be the first string-theory model with a natural mechanism for explaining why our universe would seem to exist in three spatial dimensions if it actually ...

Quantum field theory (QFT) remains the cornerstone of our understanding of particle interactions, unifying the principles of quantum mechanics with special relativity by describing particles as ...

String theory found its origins in an attempt to understand the nascent experiments revealing the strong nuclear force. Eventually another theory, one based on particles called quarks and force ...

"On one side," says Jan Zaanen, "you have this refined, almost other-worldly intellectual — the perfectionist obsessed with detail, barely interested in earthly pleasures. On the other, you have the ...

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 ...

The original version of this story appeared in Quanta Magazine. String theory captured the hearts and minds of many physicists decades ago because of a beautiful simplicity. Zoom in far enough on a ...

Stop. Look around. All things, visible or not, are made of particles so tiny that many find their sizes difficult to comprehend. Far removed from our everyday experiences, they move at rapid speeds ...
