The Alchemy of Neutron Star Collisions

The video explores the origins of atomic nuclei, highlighting that many were formed in stars and supernovae. However, recent findings suggest neutron star mergers are a significant source of heavy elements. The R process, once thought to occur in supernovae, is now linked to neutron star collisions. Evidence from meteorites supports this, showing elements formed millions of years before the solar system. The video also touches on the cosmic dark ages and recombination, explaining how the universe evolved over time.
