The hot Big Bang is often touted as the beginning of the Universe. But there's one piece of evidence we can't ignore that shows otherwise.
  • The Big Bang is the beginning of the universe, but there are mysteries associated with it.
  • Inflation divided the idea of the Big Bang into a hot, dense state and an initial singularity.
  • The Universe has superhorizon fluctuations that cannot be explained by the singular Big Bang.
  • Temperature deviations in the cosmic microwave background are caused by inflation and superhorizon fluctuations.
  • Studying the polarization of light in the cosmic microwave background can help distinguish between “singular big bang” and “inflationary state” scenarios.
  • There are superhorizon fluctuations in the Universe, which indicates an inflationary state before the hot Big Bang.
