To reconcile quantum mechanics and gravity, a new theory flips the usual script. Space-time and gravity may emerge from quantum effects, not the other way round
Detecting gravitational waves has given us a new way to observe the universe by listening to ripples in space-time. Here are five of the biggest finds from LIGO
In the recent LIGO announcement, it was claimed the event was two colliding black holes 1.3 billion years ago. How do we know this?
