... large as 0.1 millimeter, and this will be tested by gravity, which behaves as F ~ M1 M2/ rn+2 for n extra dimensions, at r < R. In these, gravity could become strong at 1 TeV and unify with the other forces there. (Nima Arkani-Hamed, Dimopoulos and Dvali) The extra dimension could be curled up with ...
