Explainer: What are gravitational waves?
Albert Einstein had predicted that large catastrophes, like colliding black holes, should produce tiny ripples in the fabric of space. In 2016, scientists reported finally detecting them

How to catch a gravity wave
Physicists have just announced finding gravity waves. The phenomenon was predicted a century ago by Einstein’s theory of general relativity. Here’s what it took to detect the waves.
