There are speculations that grand unified theories (GUT's) may arise from higher-dimensional models of gravity in which the extra dimensions are spontaneously compactified. The GUT predictions for proton decay and 2θw can be significantly modified when nonrenormalizable interactions, scaled by inverse powers of the compactification scale Mc, are added to the standard GUT Lagrangian. For example, the decay rate for p-->e+π0 in minimal SU(5) can be lowered by one (two) orders of magnitude if Mc is on the order of 1017 GeV. However, 2θw then decreases by 0.005 (0.01). The SO(10) model is also discussed.
