Well, I just came accross this site www.fractaluniverse.org, haven't read through it but it may be interesting for the scientific minds here:
What could the spatial equivalent of the Coriolis effect be? A rotating universe? Perhaps our's is a rotating, spiral universe, the last and biggest. Or perhaps there is a next spiral up; one of an infinite, fractal set. Each level would appear finite to its denizens until better technology revealed more, and more and more...
The universe consists of a series of spiral bodies of diminishing size each made in turn by plasma ejection and moulded by a spatial Coriolis effect: a rotating fractal universe.
Isn't this a good explainations of the multiple dimensions?
