Writing for The Christian Science Monitor Michelle Thaller reports on the Brane Theory for an eleven dimensional universe.
There are some theoretical reasons to believe that there are other branes out there besides our own, separated from us by a dimension we can't travel in. Cosmologists are getting pretty excited about a new model of how the universe began, with one or more branes interacting with each other. There may even be observational evidence of this in the microwave background radiation, leftover heat from the very beginning of our universe. The implications of this theory are staggering. Not only is the door left wide open to the possibility of entire parallel universes existing out there in the Bulk, but now we have the real possibility that gravity may allow us to explore them, to a very limited degree.
Brane is short for membrane and is a reference to the idea that our 3-dimensional universe might be enclosed in a higher dimensional membrane of some sort.
