Einstein’s general theory of relativity gives us a critical number the universe must meet to continue expanding at it’s current rate Ω=1 roughly 3 hydrogen atoms per cubic meter but what if Ω>1 or Ω<1?

The Big Crunch• What is it?- The universe is not massive enough to over

power gravity, in this case it will contract to a single infinitely massive point.

• When is it?- Approximately 10 billion years

• What is it?- The universe is massive enough to over power

gravity, in this case it will expand forever.

• When is it?- All stars will die in approx. 1014 (100 trillion)

years

The Big Freeze

Why?

• The law’s of thermodynamics. - You can’t have something for nothing - You can’t win - You can’t get out

•The shape of the universe
