3 IT’S ALWAYS BEEN THERE

1 An empty, infinite universe

In this scenario, the universe has existed forever and was nearly empty for that time. Then gravity took over and matter started to clump together.

2 Expanding internal region

The density of matter is such in some regions that it forms an incredibly massive black hole, the internal region of which experiences expansion.

3 A Big Crunch

Inside the huge black hole, matter again collapses under the intense gravity and increases in density up to a limit imposed by physics.

4 The Big Bang

When it can’t stand any more, quantum fluctuations cause the matter to expand outwards in a typical Big Bang scenario within its black hole universe.
