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 ...

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 ...

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 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 ...

String theory used to get everyone all tied up in knots. Even its practitioners fretted about how complicated it was, while other physicists mocked its lack of experimental predictions. The rest of ...

Researchers are demonstrating that, in certain contexts, string theory is the only consistent theory of quantum gravity. Might this make it true? Thirty years have passed since a pair of physicists, ...
