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

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

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

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 ...

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.

String theory began over 50 years ago as a way to understand the strong nuclear force. Since then, it’s grown to become a theory of everything, capable of explaining the nature of every particle, ...

Two physicists have come across infinitely many novel equations for pi while trying to develop a unifying theory of the fundamental forces Saha and Sinha are not mathematicians. They were not even ...
