[00:00:00]Two dead stars can shake the universe.

[00:00:02]That sounds impossible because stars are supposed to die and go quiet, but some dead stars become neutron stars, tiny crushed cores left behind after supernovas. If two neutron stars orbit each other, they can spiral closer for millions of years. Then, in the final seconds, they collide. The crash releases an enormous burst of energy. It can create heavy elements like gold, and it sends ripples through space-time itself. These ripples are called gravitational waves. So, two dead stars do not just collide. They make the universe ring.
