The theory that suggests that, if our universe's expansion rate doesn't exceed escape velocity, the gravitational attraction of all of its matter would cause it to contract again. Once all of the matter condenses into a single point, it would create a massive black hole, also known as the Big Crunch Singularity. This would happen once the density of the universe exceeds critical density.
I guess to believe in the Big Crunch, you'd have to believe in the Big Bang first, though.

i'd go for the big freeze |

I beileve in this theory, honestly. it sounds pretty interesting. though, yet in a way. impossible.

But they have found that the expansion of the universe is speeding up, so unless escape velocity somehow changes that won't happen.
A strange game. The only winning move is not to play. |

Im betting for the big freeze, but I hope something called the big rip might happen. Theoretically, The growth rate of the universe gets so fast that the universe rips at its seems. Its a really cool concept, even though it sounds a bit scary.
To siggy or to not to siggy, that is the question. |

"I beileve in this theory, honestly. it sounds pretty interesting. though, yet in a way. impossible."
When you think of it, it seems almost inevitable.
Think of a comet, or some other high-speed celestial body. It's orbiting the sun in an irregular ellipse. Once the comet reaches the other side of the sun, it has to reach escape velocity in order to slingshot back around. If it doesn't, it just gets sucked right into the sun.
If our universe isn't expanding fast enough for long enough, it seems very likely that the same thing would happen. But instead of everything getting sucked back into one single point, they would all collapse back on each other.

I do believe in the big crunch I'm about to make into these doritos

i can do that, just buy out a KFC for me |

At some point, it will slow down. If it doesn't maintain a speed of escape velocity before the galaxies are out of each others' gravitational influence, that's when the Big Crunch would happen.

I always thought the universe was growing at an increasing rate due to the increasing amounts of dark matter.

that dark matter be stealin our space |

" I always thought the universe was growing at an increasing rate due to the increasing amounts of dark matter."
That's another theory. If that's the case, the universe's expansion won't ever slow down. Then that would set everything up for the Big Freeze to happen.

I favour that to the big freeze theory

Makes sense. The big freeze is the one that sounds the most likely to me,though.

or 13 billion years ago or so ago where they claim the big bang happened was really just a ginat explosion that destroyed everything(Theres still debris)

This thread is making me have an existential crisis. |

"or 13 billion years ago or so ago where they claim the big bang happened was really just a ginat explosion that destroyed everything(Theres still debris)"
The Big Bang wasn't even an explosion, though. It was an expansion of space. An explosion occurs in currently-existing space.

where was the space if there was nothing

"where was the space if there was nothing"
There was no space.
