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 ...

String theory found its origins in an attempt to understand the nascent experiments revealing the strong nuclear force. Eventually another theory, one based on particles called quarks and force ...

For decades, physicists have been trying to combine quantum physics and general relativity into a single, unified theory. One of the leading contenders is string theory, an elegant vision in which ...
