Neutron Stars: Cosmic Hums and Gold

Neutron stars are so dense that a sugar cube sized piece would weigh more than Mount

Everest on Earth. These collapsed cores of massive stars pack more mass than our sun

into a sphere just 20 kilometers wide. If you could somehow stand on one, you would be instantly

flattened thinner than an atom by gravity a billion times stronger than Earth's.

But here's where it gets wilder. When two neutron stars collide, they create ripples

in spacetime itself and forge all the gold in the universe. That wedding ring on your finger was

literally born from one of the most violent explosions in space. And sound can't

travel through space because there's no air, but neutron stars actually hum.
