  I investigate the possibility of the propagation of neutrino with
superluminal speed through matter in the context of the relation between
gravity, spin and torsion. Using a lemma of Penrose and earlier works on the
relation between spin, torsion and gravity I glimpse on a frame work in which
superluminal speed of the neutrinos moving through matter become possible. In
presence of torsoin neutrinos are found to follow spacelike geodesics by
tunneling through the light cone into the spacelike region and consequently
appear to have superluminal speed in our timelike world, whereas photons always
follow null geodesics. This frame work may set new frontiers for spacetime
physics.
