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

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.

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

Visualization of the allowed values of "dial settings" in the scattering amplitudes that describe the probability for particles to interact in the models introduced in this new work. The regions in ...

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

Fifty-eight years after it first appeared, string theory remains the most popular candidate for the “theory of everything,” the unified mathematical framework for all matter and forces in the universe ...
