And if everything is rotating, and most is rotating in the same direction, it means we're probably in a black hole.

Science is going to be interesting during the next twenty years.

Why would it mean that?

I'm honestly curious.

I'm completely a layman, so don't take my word as fact. But currently there's a trend in thinking that because more than half of the galaxies they've been measured all rotate the same direction (as opposed to all random directions that a uniform static bang should result in) then the universe started out spinning in that direction.

What starts from a very small condensed state, and expands rapidly while spinning in one direction? Black holes.

Black holes also go through a life cycle that's pretty close to what we expect or universe to go through.

It's a new thought, I'm not even sure how much evidence there is past the galaxyspinning evidence. But it's interesting and has scientists thinking.

It also takes care of any "multiverse" questions, since black holes are already in a universe. Some of the holes could be pocket universes, and we could be in one, with black hole pocket universes of our own.

The observable universe is also way denser than a black hole of equivelent radius (black holes get lower in density the bigger they get) so one way or another we are in a black hole in the sense that somewhere out there is an event horizon through which you can never leave, just not in the traditional understanding which only really applies to 'small' (every single other) black holes.
