Manyfold Universe Theory

Geek-from-parallel-Universe writes "In the HEP preprints database a preprint ">appeared in which the authors propose that a world is a brane folded many times in extra sub-millimiter spatial dimensions. We see other folds only through gravity as a dark matter because light must go around the folds. If this is true then I am waiting for Star Trek-like devices: 'portable submillimeter wormhole generator' and 'personal parallel universe transmitter' to appear on the market. :-)"
