I should have added that current versions of string theory require that there be additional spatial dimensions (up to 6 or even 7 more). Since these dimensions haven't been observed, it has been conjectured that they're quite tiny (curled up into up into any of a myriad of possible shapes). The present article discusses the possibility of getting experimental confirmation of these extra dimensions.

If gravity is strong - just appears weak because it "falls though the floor" - wouldn't the dimension it's "falling" into have to be large? Or have "in common" type qualities with black holes? Hard to put a lot of something into nothing ...
