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.

The original version of this story appeared in Quanta Magazine. String theory captured the hearts and minds of many physicists decades ago because of a beautiful simplicity. Zoom in far enough on a ...

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.

1. Name the German physicist who is widely credited with first studying the general theory of relativity in five dimensions, creating the precursors of some ideas that later appeared in string theory.

String field theory co-founder Michio Kaku did not even try to explain his controversial yet undeniably brilliant cosmological theory of everything.

A detailed look at the Universe reveals that it's made of matter and not antimatter, that dark matter and dark energy are required, and that we don't know the origin of any of these mysteries. However ...
