Black holes, regions of spacetime in which gravity is so strong that nothing can escape, are intriguing and extensively ...

A new theory suggests that the unification between quantum physics and general relativity has eluded scientists for 100 years because huge "fluctuations" in space and time mean that gravity won't play ...
