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.

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 subatomic particles like ...

For decades, physicists have been stuck between two frameworks that each work brilliantly but refuse to reconcile. A new ...

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.

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

Scientists have long known that migrating birds and homing pigeons navigate in part by sensing the Earth’s magnetic fields, ...
