One theory is that if the end of the universe end in a big crunch , when everything will be in a single dense point than big bang will happen again and since laws of physics are the same , speeds of light will be the same , objects and atoms will evolve the same, stars will form again in the same way over and over again, everything will happen again in the same way. No difference.
Then i could be living this life over and over again. Pure hell , no break ever.
This is a real possibility and i know this is what's happening.
This is exactly what I was thinking the past couple days. Peculiar to see this given that I check this site less frequently...
I think that true eternity still exists, but not in the sense that there is a permanent timeline. You could consider imperceivably huge amounts of time to be virtually eternal, but it surely can't be unlimited, and somethings gotta happen after. And I think it resembles what Gonnerr mentioned. It will roll over back to the beginning.
Assuming the above is the case, it could be like OP said where time will be imperceivable in death, and we will basically hyper fast forward to when our individual lives start again.
The "time elapsing" as you're in the state of nothingness in death wouldn't be tied to the same time perceived by those still alive. You would be made to have the slowest "metabolism" possible beyond what a living thing is capable of, as the energy that once gave you consciousness and life isn't destroyed, but made dormant. Which seems like it would make time spent being dead go by in a flash, but whatever's still alive will go on as usual concurrently.
Maybe not though? I'm not as sure...
I hope that makes any sense at all, I wrote this this tired late at night.
With all that said, could someone please tell me I'm completely wrong or that my theories are flawed? Or counter with other theories? I don't want any of the above to be what might actually end up happening, I just want to forever sleep.
