Ripples in spacetime confirm Einstein's theory
Scientists detected ripples in spacetime from merging black holes, confirming Einstein's century-old prediction and opening a new way to observe the universe's most violent, invisible events.
Imagine the universe as a giant fabric; violent events like merging black holes create ripples in it, called gravitational waves. Albert Einstein predicted these waves over a century ago, and on September 14, 2015, scientists finally detected them. This groundbreaking discovery, made by the LIGO observatory, came from two black holes colliding 1.3 billion light-years away, converting immense mass into energy.
