Estrella de neutrones

The video explains the phenomenon of a star exploding in a supernova, leading to the formation of neutron stars. These stars can have twice the mass of the Sun but are only a few kilometers in diameter. Their immense gravity compresses atoms into a dense particle soup, where protons and electrons merge to form neutrons.

What happens to atoms in a neutron star due to its immense gravity?
