Experimental proof of hyperspace?

[misogynisticfeminist]

Will there ever be any form of experimental proof of multiple dimensions, even any thought experiment which would be able to proof or disprove the existence of one?

[selfAdjoint]

There are experiments that have been going on since 2000 to check that some of the compact dimensions of superstring theory may have dimensions as large as a micrometer. This would show up as a modification to the behavior of gravity at very short distances. They haven't found any such thing yet, but they haven't given up looking either.
