3 Brane universe

Anyone familiar with this? A 3 Brane is a 3 dimensional string (string theory). The idea is that our universe is a 3 B

The idea is that our universe is a 3 Brane universe is supposedly a rectangle. So, if the universe began as a "Big Bang" and expanded spherically, how could a 3 Brane universe be a rectangle?
Secondarily, there is a theory that other universes could be similar 3 Branes, separated from ours by only a couple mm from ours yet we can't see them..

Dark matter is just leakage across the boundaries of countless, tightly nested universes.

1313½ will do the maths. It's a no-Braner. :-/

I consider that a distinct possibility. And that would make the
search for dark matter a really, really frustrating task.

Dark matter is great. Can't be seen, doesn't interact with anything, the only evidence that it's there is gravimetric. If the stuff has any appreciable density anywhere and yet still can't be seen, even as a veil over something else, then it's actually invisible.

The cloaking devices of the vast, alien fleet heading this way?
Does Dark Matter show a red shift or a blue shift? Perhaps we should be told? ;-)
