One of the strangest ideas about the nature of the universe could be one of the most important. Do long, thin, and incredibly dense strands of matter called cosmic strings wind their way throughout ...

The problem with string theory, according to some physicists, is that it makes too many universes. It predicts not one but some 10 500 versions of spacetime, each with their own laws of physics. But ...
