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 ...

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

In 1980, Stephen Hawking gave his first lecture as Lucasian Professor at the University of Cambridge. The lecture was called "Is the end in sight for theoretical physics?" Forty-five years later, ...

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 ...

A new study just added an interesting twist to the complicated history of the physics theory.

At the turn of the century, it sounded as if string theory could give us big answers about the universe. Well… has it? String theorists, this one may be for you. The theorized object warps spacetime ...

Event display in the signal region from data taken in 2018. The pixel tracklet candidate with p T = 1.2 TeV is shown by the red solid line and other inner detector tracks by the thin orange lines.
