The most stars a person can see with the naked eye? About 8000.
And, less than half that, actually — since we can’t see the other side of the hemisphere

Re: How many supernova explode every year?
#22If I got the math right, then about 1 in every 32,000 stars in the universe goes supernova each year. That's scary. But I think I'm getting the math very wrong. edit: I guess my error might be related to confusing a probability factor with the number of incidents in a period. edit: The right answer is probably up to 1 in every 10bn stars go supernovae in the universe each year (or 1 in 10bn die and a fraction are sup…

Re: How many supernova explode every year?
#23We'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…
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.
The comparison can be made; almost all positive integers can't practically be represented in hindu-arabic because they are too large. If we're dealing with numbers that can be scribed in a few seconds they are small in a meaningful way.
We'd expect that the mathematicians would need to come up with a new notation to represent the age of the universe.

#24The universe is vast and full of nothing... Which in case of explodey stars is a very good thing indeed!
It's fun to think that at some point it will be actually vast and completely dark

If you need some existential dread. It's a hypothetical video to portray the rest of the universe, the time speed moving forward doubles every 5 seconds - and it's 29 minutes long...

#25Absolutely mind-blowing how much our ability to observe the universe has exploded

Can’t be right, can it? It would make the Sun (over 4 billion years old) an enormous outlier.
It also would mean stars, on average, do not get very old. Over 10% of the stars that the ancient Greeks saw in the sky would have to have gone supernova since then.

#28That'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.
Honestly one of those rare games that makes you feel like a real explorer, not just someone following a path the devs laid out.

He mentioned a rough estimate of one per century per galaxy. Estimate for average stars per galaxy is 100 million, which would be 1 in 10 billion stars every year
