Singularity and Momentum

[ParanoiA]

I posted this in the pseudoscience area and then noticed the last post in there was 2 or 3 weeks ago. I'm guessing it doesn't get looked at much. So, I thought I'd try it in here. I apologize if it's out of place, although I don't think it is.

 

I'm having a hard time understanding the multiverse theory. I thought I read some time ago, that the universe as we know it is like two plates moving away from each other, or expanding, set in motion by the big bang...and that they eventually come back together, singularity, and then big bang again..and so on.

 

Now when I look up information on it, I see no mention of that part. Just dimensions.

 

I'm wondering if this "expansion" and eventual "collapse" happen at different momentums, creating differences in physics and time. I would think the speed at which the plates move apart and come back together would have an impact on the vacuum within it. Is that true?

 

Does any of that even make sense? Or did I just dream all this...?

Yes, in the Cyclic model, Dark energy corresponds to a force between the branes.

(Guessing Cyclic Universe is what you are asking about, but not sure.)

But instead of a universe springing forth in a violent instant from an infinitely small point of infinite density, the new view argues that our universe was created when two parallel "membranes" collided cataclysmically after evolving slowly in five-dimensional space over an exceedingly long period of time.
