Heaven is eternal oblivion. Nothing to worry about. Nothing to wait for. Nothing to regret. No pain, no dreams, no fussing, fussing, fretting, no hand wringing, no nothing. Nothing, nothing, nothing, nothing at all.
Not if NIetzsche’s Eternal Recurrence is true. Then we get to do this fucking shit all over again, again and again for eternity, without any memory of having done it before.
What's the difference?
Einstein's block universe suggests that every part of our life is always there; We don't do it over and over, we are "always" doing all of it.
But it amounts to the same thing in all three cases. One through, repeatedly through, Or not through at all (with going "through" just an illusion caused by present memories at every point), these are all indestinguishable, and knowing which (if any) is "true" does nothing whatsoever to alter the experience or the situation.
That’s true, but what it also means, it seems, is that you are never permanently “out” of existence. Your existence is eternally there, between birth and death. So it seems there would be no eternal peace of the grave.
There's never any ephemeral peace of unconsciousness either though, so we litterally cannot and will not be missing anything.
When I had my wisdom teeth extracted I was under general anaesthesia for over an hour (I was a particularly complex case), and my experience jumped straight from the pre-op room with the anaesthetic being injected, to the recovery room. I didn't experience any period of "peace", and I see no reason to think the experience would have differed for me in any way if I had died during the operation.
Insofar as we feel "peace" in sleep, it is because of the presence of experience - dreams or dreaminess - not its absence.
When I am sufficiently tired, sleep is more like anaesthesia, with no transition at all between dropping off and waking up.
I expect death to be much the same, but wothout the "waking up" part.
