  • Gravity separated from the fundamental forces (10^-43 seconds)
  • Strong force separated from the fundamental forces (10^-36 seconds)
  • Inflation stopped (10^-33 seconds)
  • Electromagnetism and the weak force separated (10^-12 seconds)
  • Quarks and gluons formed protons and neutrons (10^-6 seconds)
  • Protons and neutrons formed nuclei (a few minutes)
  • Nuclei and electrons formed atoms (379,000 years)
