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

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 ...

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.

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 ...

String theory's equations give rise to a near infinite variety of potential universes in a 'landscape.' This landscape is surrounded by a 'swampland' of solutions that are incompatible with any ...

What is string theory: It replaces point-like particles with tiny vibrating strings, requiring extra dimensions to reconcile gravity with quantum mechanics. Why it matters: String theory could unify ...

String theory proposes that the fundamental constituents of the universe are one-dimensional “strings” rather than point-like particles. What we perceive as particles are actually vibrations in loops ...
