String theory has finally made a prediction that can be tested with experiments -- but in a completely unexpected realm of physics. The theory has long been touted as the best hope for a unified ...

Eight decades have passed since physicists realized that the theories of quantum mechanics and gravity don’t fit together, and the puzzle of how to combine the two remains unsolved. In the last few ...

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 ...

Modern string theory postulates that the elementary constituents of matter are tiny one-dimensional, string-like objects ...

A Harvard theoretical physicist has discussed with scientists at the Large Hadron Collider in Switzerland the possibility that they may discover a theorized “stau” particle, with a lifetime of a ...

String theory has long been touted as physicists' best candidate for describing the fundamental nature of the universe, with elementary particles and forces described as vibrations of tiny threads of ...

String theory may provide the best clues yet about how to obtain a unified theory that describes all the laws of nature, but do we even understand what string theory is? Download PDF Albert Einstein ...

Researchers are demonstrating that, in certain contexts, string theory is the only consistent theory of quantum gravity. Might this make it true? Click to tell Google to prioritize Quanta and see more ...

The idea of String Theory is that our Universe came from a higher-dimensional, more symmetric, more complex state with an enormous number of degrees of freedom. In order for String Theory to be solved ...

How long’s a piece of string? You may want to sit down for a minute. Gnu2000 String theory entered the public arena in 1988 when a BBC radio series Desperately Seeking Superstrings was broadcast.

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 ...

It's one of the most brilliant, controversial and unproven ideas in all of physics: string theory. At the heart of string theory is the thread of an idea that's run through physics for centuries, that ...
