The Big Freeze

So, there are three popular theories as to how the Universe will end.

These theories include "The Big Crunch"- which is the theory that suggests that the Universe will succumb to the power of its own gravity and will ping back into the infinitely small point from which it started, thirteen and a half billion years ago.
From The Big Crunch, another Big Bang will happen.
This theory goes by the rule, "what goes up, must come down".

The second theory is known as "The Big Rip" which says that the Universe will continue to expand until everything- right down to atoms and subatomic particles- will be torn to shreds.

The Big Crunch theory has been considered the least likely fate of the Universe since the discovery
of "Dark Energy".
This Dark Energy seems to be accelerating the expansion of the Universe at an incredible rate, implying that it is more likely that the Universe will continue to expand forever- which brings me on to "The Big Freeze".



The Big Freeze theory says that the Universe will continue to expand forever, until it becomes a very cold and lonely place.
It will become so cold, however, that new stars cannot be born and so the stars that exist at the time of the Big Freeze are the very last ones.

These stars will then die, explode in supernovas and many will become Black Holes.
The Universe will, therefore, be a racetrack with Black Holes racing around, everywhere.
They will then suck in the remaining stars and planets.

Surprisingly, Black Holes - after a while - can actually disappear.
As a result of this, the Universe will become a dark and lonely void - with maybe the odd frozen rock here and there.
