  • 'start' of universe

  • scientists are unsure what happened before

  • infinitely hot

  • infinitely small

  • the singularity

  • all matter, energy, space, and time are created

  • immediately after Big Bang

  • no matter, only energy and superforce (gravity, strong nuclear, weak, electromagnetic)

  • gravity split from the superforce
