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.

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.

String theory might be the theory of everything… or a flawed framework for theoretical physics. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.

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 ...

In October 1984 I arrived at Oxford University, trailing a large steamer trunk containing a couple of changes of clothing and about five dozen textbooks. I had a freshly minted bachelor’s degree in ...

String theory is perhaps the most high-profile candidate for what physicists call a theory of everything – a single mathematical framework capable of describing the entirety of the known universe. The ...
