How the Big Bang Ends up Inside a Black Hole

Understand

The standard model of cosmology assumes that our Universe began 14 Gyrs (billion years) ago from a singular Big Bang creation.

• This can explain a vast range of different astrophysical data from a handful of free cosmological parameters.
• However, we have no direct evidence or fundamental understanding of some key assumptions: Inflation, Dark Matter and Dark Energy.
• Here we review the idea that cosmic expansion originates instead from gravitational collapse and bounce.
