We suggest a mechanism by which four-dimensional Newtonian gravity emerges
on a 3-brane in 5D Minkowski space with an infinite size extra dimension. T
he worldvolume theory gives rise to the correct 4D potential at short dista
nces whereas at large distances the potential is that of a 5D theory. We di
scuss some phenemenological issues in this framework. (C) 2000 Elsevier Sci
