Lower dimensional universe

I just saw this on PhysOrg.com. It sounds kind of mind blowing, and I'm not sure I really have any thoughts about it yet. It seems that some physicists have proposed that our universe may have started out as just one dimension. Then as that dimension expanded and the energy level dropped it switched to 2 dimensions. As the expansion continued and the energy level continued dropping it switched up to the current 3 dimensional universe. The time dimension of course has to be added to all 3 configurations. So the 1 dimensional universe had 1 space dimension and 1 time dimension (1+1). They claim to have detected what could be a signature of the 2+1 version.

As an aside I just finished reading "The Black Hole War" by Leonard Susskind. In it he tells how they did a lot of theoretical research using 1 and 2 dimensional universes, since the physics is a lot simpler. Whether that would work in with this subject is open for question.
