Neutron Stars and Element Formation

The video explores the role of heavy metals like iridium, gold, and lead in car manufacturing and delves into the mystery of how these elements are formed in the universe. It highlights the limitations of supernovae in creating heavy elements and introduces neutron star mergers as a more plausible source. The video presents evidence from NASA's Swift satellite and the Hubble Space Telescope supporting this theory. It concludes with the formation of Earth and the distribution of heavy metals, explaining their significance in modern technology.
