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

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.

In this video, we explore the relationship between string theory and quantum field theory (QFT). QFT is a mathematical ...

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