New scientific observations of Neutron star collisions, a rare cosmic event, suggest that they are the source of elemental gold in the universe. Originally, astrophysicists believed that all matter was synthesized in supernova star explosions, where tremendous amounts of energy bond sub-atomic particles of hydrogen and helium together into heavier elements. However, it is now suggested that the heavier metals, like gold, platinum, uranium, and other dense elements are created in the collision of two neutron stars, which are much denser stellar remnants of massive stars leftover after nuclear decay. A collision of two of these bodies would provide much more energy than a traditional supernova explosion, crushing together denser elements. This could count for the relative scarcity of these materials, as neutron star collisions are much more rare events in the cosmos.
