I read in a recent Analog science article (~before June '85) that
cosmologists are postulating the existence of about 7 more spatial
dimensions to account for the actions of the 4 forces in an attempt
to unify them all.  The dimensions would be rather small, and 
"travelling" in them wouldn't make sense.
