String theory may be our best attempt at a theory of everything, except that it can't describe an expanding universe like ...

For decades now, many physicists have pursued the hope that equations involving an especially tiny "string" could provide 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?

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.

His contributions to string theory have been myriad, including the time in 1995 when he gave the then somewhat moribund field a much-needed boost by showing how the five different variations of ...

Together, they are finding common ground, where string theory can be applied to the physics of quark–gluon plasma. High-energy accelerators usually collide particles such as electrons or protons ...

Theoretical physicist Michio Kaku explains why he thinks string theory is the best way to understand how the universe works. Consumer inflation expectations could creep into the Federal Reserve's ...

WIRED is where tomorrow is realized. It is the essential source of information and ideas that make sense of a world in constant transformation. The WIRED conversation illuminates how technology is ...
