If this post goes where I hope it goes it will roughly tie into the god thing. I always enjoy listening to concepts non scientific people have of the universe, this would include myself. I imagine the universe as being perfectly balanced and smooth running. Now if I could watch a video of the universe from it’s inception until now and I had the option of speeding it up at what speed would I start to think tt was chaotic with no organization? Or if it would ever appear this way?.
IMO as long as the action in teh vid is proceeding at a pace your brain can watch & follow it’ll appear as organized as it really is. Which might be smooth or might be chaotic depending on which scale you’re focusing on.
At which phase of the Universe’s evolution? The early Universe, viewed in real time, would be incomprehensibly fast to a human.
Will it continue to slow down? Or has it reached a stable point?
I mean, eventually you get to the point where the only action is the eventual decay of supermassive black holes. And eventually after that, so far as we can tell, nothing at all happens any more. Doesn’t get much slower than that.
Apparently it is waaaay faster than previously thought! (of course, “faster” is a relative term here)
That’s just for white dwarfs, and they’d (probably) die via proton decay long before that anyway. The last things in the Universe to decay would be supermassive black holes, at around 10^97 years.
Well, here are a couple of movies that you can watch at whatever speed you choose.
Big Bang to (approximately) now
From approximately now until the end (time scale doubles every 5 seconds and it is still ~30 minutes long)
Is proton decay still considered to be a real possibility?
I thought the concensus these days was that it doesn’t happen… at least, every time they have built a more sensitive instrument looking for it, none has been seen…
Well, all those experiments can do is put lower bounds on the proton’s lifespan. But so far as I know, every single model that unifies the strong and weak forces ends up predicting proton decay over some timescale or another, and all of those timescales are extremely long, and many of them longer than the experimental bounds. Though even the longest predicted proton lifespans, which are far beyond the bounds of our ability to measure, are still much shorter than the predicted lifespans of black holes.
Looks like I need to start on my bucket list.
