    Big Bang

    The cosmos goes through a super fast "inflation" expanding from the size of an atom to that of a grapefruit in a tiny fraction of a second.

    10^-32 Seconds

    Post inflation the universe is. seething hot soup of electrons quarks and other particles.

    10^-6 Seconds

    A rapidly cooling cosmos permits quarks to clump into protons and neutrons.

    3 Mins

    Still too hot to form atoms, charged electrons and protons prevent light from shining: The universe is a super hot fog.
  • 1 BCE

    300,000

    Electrons combine with protons and neutrons to form atoms, mostly hydrogen and helium. Light can finally shine

    Gravity makes hydrogen and helium gas coalesce to form giant clouds that will become galaxies: Smaller clumps of gas collapse to form the first stars.
  • 1 BCE

    15 Billion Years

    As galaxies cluster together under gravity, the first stars die and spew heavy elements into space: those will eventually turn into new stars and planets
