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 subatomic particles like protons and the quarks and gluons that make them up.

For decades, scientists have theorized about what lies beyond the third dimension and if there can exist a unified theory to explain all of the workings of the universe. This insurmountable task has ...

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

It's one of the most brilliant, controversial and unproven ideas in all of physics: string theory. At the heart of string theory is the thread of an idea that's run through physics for centuries, that ...
