Neutron stars are the densest things that are not black holes.

00:05

In their cores, we might find the most dangerous substance in existence:

00:10

00:11

A bizarre thing so extreme,

00:14

that it bends the rules of the universe

00:16

01:23

They desperately push back against gravity, against the collapse.

01:27

If gravity wins, they will become a black hole.
