If you could take an apple and break it into smaller and smaller parts, you would find molecules, then atoms, followed by ...

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 ...

The largest-ever survey of physicists from around the world—released today—shows a distinct lack of consensus across many of ...

Tenets of quantum mechanics and special relativity, among other theoretical ideas, lead inexorably to string theory.

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 ...

Brian Greene is one of the foremost scientists and science communicators of our time. Greene, a theoretical physicist at Columbia University, has been working for decades to advance our understanding ...

A new theoretical study suggests that the mysterious force driving the accelerated expansion of the universe—known as dark energy—may actually be rooted in a deeply quantum structure of space-time.

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 ...
