A physical argument for an afterlife

[JuliaL]

The question of afterlife is a very interesting one but obviously equally fruitless. We may be constructing hypotheses all we want but according the the scientific method, there has to be an experiment to prove them. In some cases this technically equals returning from the dead. Today the experiments either disprove the afterlife hypotheses or the hypotheses are so that there's no possible experiment to test them yet (as in with the existance of the Creator or other universes or anything like that).

Returning from the dead isn't going to be very useful in proving an afterlife unless you remember what you were doing while you were out. Even if you did remember, there's no guarantee that your memories aren't false. As I am happy to point out to theists who want to tell me all about the afterlife; I'm not interested in what you think my eternal and indestructible soul will be doing throughout eternity if you can't tell me where it went last night between about 10:30PM and this morning when I got up.

My own non-scientific view is that there may be some kind of symmetry involving the presense of the observers in our Universe. In other words it's some kind of conservation law-based "re-incarnation" without any kind of soul involved (at least not as we mean it). It's something like you die and without any comprehensible transitional process appear (get "born" in a one way or another) completely blank, without any knowledge or memories from the past.

Sounds like Hawking Chronology Protection Conjecture
I'm not sure if you are insisting on conscious observers or not. But I don't grant much primacy to sentience. I think it is an emergent and wholly material phenomenon developed by natural selection which gives an edge to those organisms who actually want to preserve themselves.
