HUGE SPOILER ALERT. SERIOUSLY, PLAY OUTER WILDS. It's a little more than just " the sun will also go supernova". The core conceit of the games story is that you're living in the final moments of dying universe.

Oh. Whoops. I thought you were saying the other comment was a huge spoiler, not that YOURS was, and I was like "eh, it's not THAT big of a spoiler." Ah, well. With that mystery abolished, time to return to the likes of Mario!

Can the thread title be rewritten to be less obnoxious? “How many supernova explode every year?” is fine. This isn’t Reddit. Thread titles should not imply some kind of personality or use cliche meme speak. The all caps is definitely an abomination.

Please read the article along with bikeshedding titles. It's a good one.

No. The title sounds like low effort clickbait trash.

Maybe they will have to transition from Base 26 counting to Base 64!

It's in the article. SN2067aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa vs SN2067aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa. Apparently astronomers find base26 very straightforward and reasonable!

No wonder the Millennium Falcon takes so longer to calculate its jump to hyperspace. Tens of thousands a year is one an hour! There are so many supernovae you really could bounce too close to one and that would end your trip real quick

Star Wars takes place entirely within one galaxy, and the number of supernova per galaxy is something like 1 per century, so, nah, Han was just bullshitting to stall for time while his busted-ass computer cobbled together numbers.

Not only that, it happened a long long time ago. I'm no astronomer; would that be more or less supernovae?

Isn’t the answer infinity? We don’t know what’s beyond observed part of universe, and there’s infinity number of universes. If our emerged then there’s others.

There is no reason to expect any particular number of universes. We've observed exactly one, this one, which had to exist or else we wouldn't be here to observe that it existed. Our universe is finite, so although it is unbounded (lacks edges) there aren't an infinite number of anything in it, galaxies, stars, M&Ms, grains of sand, atoms of hydrogen all finite.

Has that really been established? The observable universe is finite, yes, but I wouldn't think that automatically implied that the universe as a whole is.

The 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.

This reminds me of this quote from Jill Tarter of SETI, specifically the last sentence: “Might it be the discovery of a distant civilization and our common cosmic origins that finally drives home the message of the bond among all humans? Whether we’re born in San Francisco or Sudan or close to the heart of the Milky Way Galaxy, we are the products of a billion-year lineage of wandering stardust. We, all of us, are wh…

Too idealistic view on human nature. We discovered vastly different cultures in the past, no hint of humility (rather exact opposite) or bonding, unless we find a common enemy.
