Where does gold come from? We always thought it came from supernovas but it doesn't. However supernovas sometimes make neutron stars. Thanks to LIGO and astronomers, the people who found gravity waves, a hundred second event showed us that gold comes from colliding neutron stars. Neutron stars are uniquely dense. A Neutron star is more massive than our sun but has collapsed to the size of London. 1 teaspoon of Neutron star weighs a billion tons. The gold produced by the collision we 'saw' is about the mass of 12 solid gold Earths. Along with gold more of the very heavy elements like Platinum and Uranium are produced.
