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

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

In 1980, Stephen Hawking gave his first lecture as Lucasian Professor at the University of Cambridge. The lecture was called “Is the end in sight for theoretical physics?” Hawking, who later became my ...

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 have proposed a new model of space-time based on string theory to explain dark energy. Their hypothesis suggests that, at extremely small scales, space and time behave differently from how ...

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

(via Sabine Hossenfelder) Over the past decade, string theorists have struggled to reconcile their elegant mathematical theory with the reality of our observable reality, inventing what has been ...
