Re: How many supernova explode every year?
#2The whole things seems like such a massive living system that I cannot help guessing that what we think of as universe is just a somewhat large single creature.

#3The universe is vast and full of nothing...
Which in case of explodey stars is a very good thing indeed!

#4We're dealing with the sum total of everything, if the true nature of things is that there are a finite number of supernovas I'd be surprised. The real shock is how small the number of supernovas is and how young everything seems to be in the known universe (the age of the observed universe is estimated at maybe double digit billion years).
These are tiny numbers given that we're quite possibly dealing with infinity in both time and space. I judge it one of the stronger arguments in favour of the universe being constructed (or, more likely, there is a lot out there we can't see). If god built a universe numbers like 1 supernova a century make some sense for artistic value.

Isn't the observable universe finite? There can't be a infinite number of anything in a space of radius R, even if R is very big.

It's an appealing idea, but surely there'd be insurmountable problems with the distance/time involved for any part to communicate to another part? It'd be like trying to run a computer with a clock that takes millions (billions?) of years to make a single tick. I just don't see that it's at all feasible and that's without even trying to guess as to how different parts can change behaviour depending on its environment (one commonly used requirement of "life").

Anything moving beyond the Cosmological Horizon can no longer be seen.
As I understand it, a frozen image will remain for a time and fade, growing increasingly red shifted.

#8I couldn't spot the supernova and there's no answer to where it is. :'(

#9That's one of my favourite hints in Outer Wilds. You will see a Supernova. Not with a fancy telescope, it's visible to the naked eye, and if you watch the sky you'll see another soon enough. You can see this right at the start, and unlike the random direction of the probe launch you don't need any game lore to, if you're smart enough, put two and two together.

You can't compare a number of years or events with infinity. Saying it's tiny or huge makes no sense whatsoever.
What amazes me is how young the universe is compared to life. The universe is only about 4 times as old as life on Earth.
