Physicists searching for a better understanding of quantum gravity stumbled upon something unexpected: the defining signatures of string theory.

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

If you could take an apple and break it into smaller and smaller parts, you would find molecules, then atoms, followed by subatomic particles like protons and the quarks and gluons that make them up.

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 ...

Explore the fascinating concepts of string theory, a fundamental framework in modern physics that describes how the universe is built from tiny, vibrating strings. This video delves into the ...

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, ...
