INSIGHT

We Are Made By Stars

  • Most of the atoms in our bodies formed long before Earth and were recycled through stars and supernovae.
  • Saying we are "made by stars" captures that atoms were forged elsewhere and later rearranged into life.
INSIGHT

Boron And Beryllium Come From Spallation

  • Beryllium and boron are not forged inside stars via standard nucleosynthesis.
  • They form primarily through cosmic ray spallation when high-energy particles break apart heavier nuclei.
INSIGHT

Cosmic Rays Create Atmospheric Showers

  • Cosmic rays are high-energy particles (protons, nuclei) constantly bombarding Earth and producing particle showers in the atmosphere.
  • Those showers create muons and other particles that reach the surface and provided early evidence for time dilation.
