What it took to collect these 54-million-year-old photons from a supermassive black hole
Two black holes, each about 30 times as massive as our sun orbited each other for millions of years. An instant before they collided they sent a gravitational shiver across the universe. LIGO scientist Amber L. Stuver explains. Animation by Eoin Duffy.
More than a billion years ago and a billion light years away, two black holes merged. This was a truly cataclysmic event a long time ago in a galaxy far, far away. In Star Wars Darth Vader tells us not to “underestimate the power of the dark side.” This amazing discovery shows how right he was.
Two black holes, about 29 times and 36 times the mass of our sun, collide in this computer visualization of the event that provided the first direct evidence that black holes exist, can exist in a pair, and can collide and merge. Read more.
