[00:00:00]When a massive star, 10, 20, 30 times the mass of our sun, exhausts its nuclear fuel, it collapses.

[00:00:10]And not slowly.

[00:00:11]In less than a second, the entire core implodes.

[00:00:16]Then the outer layers slam into that core and bounce back in an explosion so bright, it briefly outshines entire galaxies.
