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

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

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

Physicists may have uncovered a surprising new clue that string theory—the idea that the universe is built from unimaginably tiny vibrating strings—could be more than just a mathematical fantasy.

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

In this video, we explore the relationship between string theory and quantum field theory (QFT). QFT is a mathematical framework that describes nearly all particles and forces in the universe but ...

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 ...
