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 ...

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.

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

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

String theory, which some physicists hope may be able to unify gravity and quantum mechanics, may have found a real-world application. A type of black hole predicted by string theory may help to ...
