 Avi Loeb has written another great essay, "Astronomers have recently determined that rare elements such as gold and uranium are produced as a result of rapid capture of free neutrons during the merger of two neutron stars. Neutron stars are the densest stars known, having the size of a city (12 kilometers) and up to twice the mass of the sun, with the density of an atomic nucleus. A teaspoon of neutron star material weighs a trillion kilograms, as much as a tall mountain on Earth."
