But despite its extraordinary popularity among some of the smartest people on the planet, string theory hasn’t been embraced by everyone–and now, nearly 30 years after it made its initial splash, some ...

String theory remains elusive as a 'provable' phenomenon. But a team of physicists has now taken a significant step forward in validating string theory by using an innovative mathematical method that ...

It’s not easy being a “theory of everything.” A TOE has the very tough job of fitting gravity into the quantum laws of nature in such a way that, on large scales, gravity looks like curves in the ...

After writing a 400-page book on string theory and then helping NOVA translate that book into a three-hour documentary, would Brian Greene, we wondered, have anything more to say about string theory?

Scientists have found what they say is a link between complex number theory and string theory. A mathematician and physicist working together found the connection, which they say is part of plotting ...

The belief that all physical matter is made up of vibrating elements called "strings." Officially known as "superstring theory," it differs from traditional physics, in which all matter is made up of ...
