Science, as it now defines itself, will never accept the paranormal and related phenomena, let alone the possibility of an afterlife, no matter how much evidence is gathered and no matter how convincing that evidence is, because science has never developed the conceptual or intellectual tools or the vocabulary to handle such possibilities.
Accepting this possibility would redefine science!
Science will only accept the paranormal and the possibility of an afterlife when a new theory of physical reality emerges, such as a unification of general relativity and quantum theory in physics, that fundamental properties. This new theory of reality can only be accepted by science for purely physical reasons that have nothing to do with the paranormal implications that will emerge naturally and logically from the theory
That would be revolutionary, and it is happening right now!
