this I guess is the core issue for me.
For me too. That's why i'm largely agnostic spiritual... well, agnostic atheist spiritual. Atheist being towards religion bc i don't think any one religion knows and/or has the full picture.
I think the observer thing is a physics phenomena... which, one guy explains well but i forget his name. He was on Joe Rogan's podcast. Basically, he says it's different than what people think it is, but then when he explained it... it sounded like what people say it is lol. Idk, i will gladly admit my ignorance of science. But i think what you're talking about is the "observer problem" in relation to schrodinger's cat experiment. There is one scientist that believes in the many worlds hypothesis to answer this paradox... but the many worlds hypothesis just sounds like a watered down... well, what we are talking about.
I'm agnostic spiritual bc of your last questions. Ignoring the easiest answer... death = you're gone. If there something other than what could that look like? I think answering the questions of who you are to the platform is more important than trying to understand the platform itself. But it is fun, so i basically have two versions... god evolved or god has always been. God being the platform. Like i mentioned early, if it evolved, then it could just wake up out of nothing and go from there. If it's everything, then simply there never was/is truly "absolute nothing" ..
Interestingly, listening to the same scientist i think it was, even empty space is something. There is something going on everywhere in our universe. So, is it really expanding and outside of its expansion is absolutely nothing? I don't know... but it makes less sense to me. Two things don't make sense... one is all of this being finite, infinite fits better bc then finite you have to describe the "wall" that it all stops at. And, second, there once being nothing. If there ever once was nothing... i think consciousness is the only thing that can emerge from absolute nothing... everything else, to my layman understanding, seems like it needs something. It's a hard question we can only have a hypothesis/speculate on. But we do have powerful brains and are conscious and evolve... so maybe we're just not ready to know these answers yet.
