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

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

Scientists are on the trail of a mysterious five-particle structure that could challenge one of the biggest theories in physics: string theory. This rare particle—never seen before and predicted not ...

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 ...

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 ...

Scientists seeking the secrets of the universe would like to make a model that shows how all of nature’s forces and particles fit together. It would be nice to do it with Legos. But perhaps a better ...

I recently read a piece on string theory. It referenced the books “Three Roads to Quantum Gravity” by Lee Smolin, a professor at Penn State, and “The Elegant Universe” by Brian Greene, a professor at ...
