  It is suggested that the mechanism responsible for the resolution of the
gauge hierarchy problem within the warped geometry framework can be generalized
to provide a new explanation of the extremely tiny vacuum energy density rho_V
suggested by recent observations. We illustrate the mechanism with some 5D
examples in which the true vacuum energy is assumed to vanish, and rho_V is
associated with a false vacuum energy such that rho_V^{1/4} ~ TeV^2/M_{Pl} ~
10^{-3} eV, where M_{Pl} denotes the reduced Planck mass. We also consider a
quintessence-like solution to the dark energy problem.
