Earth's gold formed by stellar collisions, scientists say

The video discusses the observation of gamma ray bursts and the collision of neutron stars. It reveals that such mergers, occurring once every 10 millennia in our galaxy, eject heavy elements like gold. Scientists estimate that these events produce gold equivalent to the weight of 10 moons.
