Coherence with science

Superimmortality is coherent with science as a whole. This means that it does not contradict scientific concepts, laws, and principles. It needs no supernatural concepts, objects, beliefs, or principles like magic, souls, or gods, ghosts, spirits, heaven, hells, reincarnation, resurrection, spirit worlds, ESP, near death experience created after death worlds etc. Superimmortality is also internally coherent, and clears up many of the confusions that philosophers have run into over time dealing with personal identity, life after death, immortality, personality identity, and body identity.
