String theory strutted onto the scene some 30 years ago as perfection itself, a promise of elegant simplicity that would solve knotty problems in fundamental physics—including the notoriously ...

Theorists from the Institute for Advanced Study have proposed a way forward in the quest to test string theory. Two theorists recently proposed a way to find evidence for an idea famous for being ...

String theory has so far failed to live up to its promise as a way to unite gravity and quantum mechanics. At the same time, it has blossomed into one of the most useful sets of tools in science.
