Being a scientist myself, I think it would be very difficult if not impossible to prove conclusively that OBE's exist and then write a peer reviewed article on the results. Scientists like hard facts/evidence. The first step would be coming up with a scientific experiment to test OBEs. Maybe have someone in one room astrally project and then figure out things in another room? But then that may just prove that the person is a psychic, not necessarily astral travelling. We need some device that could record astral bodies to prove OBE's.
