MAJOR QUANTUM GRAVITY BREAKTHROUGH COULD SPARK A NEW 'THEORY OF EVERYTHING'

Quantum gravity has long baffled scientists. Now, a breakthrough discovery could change physics forever

What happens inside a black hole? How did the Big Bang begin? How do forces unite to form the cosmos? Scientists could be closer than ever to answering humanity's biggest questions because they've finally found a way to measure gravity in the quantum world.

Using a new technique, a team from the UK, the Netherlands and Italy detected a weak gravitational pull on a tiny particle. So tiny was the particle, in fact, that it's the smallest mass at which gravitational signals have ever been recorded.
