  The apparent violation of causality in the brane Universe can be avoided by
taking the bulk spacetime modelled by a 5-dimensional Kaluza theory with
factorizable ansatz for the 5-dimensional metric whose components do not depend
on the fifth coordinate and with $G_{55}$ not a constant. The geodesic in the
bulk does not correspond to a free particle. The Kaluza scalar makes it
non-inertial. The implication on the neutrino experiment is that there is no
superluminal propagation even after invoking sterile neutrinos.
