The big question is why we experience the universe in only three spatial dimensions instead of four, or six, or nine.
M-Theory -- 'M-Theory' is the name of the unknown theory of everything which would combine all five Superstring theories and the Supergravity at 11 dimensions together. The theory requires mathematical tools which have yet to be invented in order to be fully understood. The theory was proposed by Edward Witten. The following article is somewhat technical in nature, see M-theory simplified for a less technical article. M-theory's relation to superstrings and supergravity...
