When two black holes collide, they warp the very fabric of space and time.
In short: When supermassive black holes merge, they release gravitational waves and intense light. This video explores the mechanics of these cosmic collisions, explaining how gravity draws these massive objects together until they fuse into one, fundamentally altering the space around them.
As two supermassive black holes approach one another, their gravity pulls in gas from the surrounding galaxy, forming a doughnut-shaped disk. This gas heats up, creating luminous jets of light visible across the universe. As the black holes circle closer, their magnetic fields intertwine until they finally plunge together, merging into a single, larger black hole.
This merger releases gravitational waves that ripple outward, warping the fabric of space and time. While Einstein predicted these waves, experimental detection has only recently become possible. Astronomer Janna Levin has studied the first recordings of such an event, which occurred 1.3 billion years ago.
