Query: Extra dimensions and violations of Lorentz symmetry   We use experimental limits on Lorentz violation to obtain new constraints on
Kaluza-Klein-type theories in which the extra dimensions may be large but do
not necessarily have units of length. The associated variation in fundamental
quantities such as rest mass must occur slowly, on cosmological scales.
