Also, as a cousin comment alludes to, for there to be one of the above supernovae, there will also be a supernova named SN2067iamsoverystupidoopssorry and a SN2067thisnamingschemawasabadidea

I guess we’re already hitting four letter words, was there a supernova “butt” last year?

No, but this is close: https://www.wis-tns.org/object/2024ass

Question for you and commenter above, do you play games with controls similar to Outer Wilds often? Do you play many games in general? I've seen this comment a few times and I'm curious why this is such a common talking point. I thought the controls were very intuitive, so I'm curious if it's a familiarity issue or something else.

The thing about Outer Wilds for me is that it's a game about exploration, but most attempts at exploration are punished (limited time frame, sands suffocating you, "ghost matter" kills...). They stuck with a "hard scifi" control scheme where you control your character in 6dof with inertia, which makes some things unnecessarily hard and did not (IMO) add anything to the game itself. The things you interact with in the…

Did you play with a controller by chance? Asking because I prefer first person view games on PC

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.

I love how you respond to a huge spoiler comment with another huge spoiler! At this point I will never play this game, I guess

It isn’t that much of a spoiler. You find all this out in the very first part of the game.

If that’s enough to ruin the game for you, then it’s not much of a game. Even if it is a big spoiler for you it’s not that big of a loss IMHO - there are so many great games and so little time. The time you don’t spend playing OW you can spend playing something else.

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.

There's something kinda poetic (and maybe even logical) about the idea that what we perceive as scattered galaxies and physics is actually just the internal processes of something far bigger than we can comprehend.

Some might call that God. Or at least some form of Pantheism

Yes, the game told me it was the preferred way and I followed the advice

I really feel like this article should also mention the rate of formation of new stars. According to [1] Universe Magazine the James Webb telescope has revealed that more than 3,000 stars are formed every second. [1] https://universemagazine.com/en/james-webb-comes-closer-to-r...

I don't understand this comment. Like yes, 3000 stars per second, cool fact. But why would that fact make sense in the article? The article was about being surprised by the name "SN 2021 afdx", which has nothing to do with star formation.

In my opinion the article was great and is also complete. More cool astronomy facts belong in some other article or format.

Because the amount of stars that can go supernova is limited by how many stars there are in the first place? A comment about the staggering rate of star formation makes sense to me in relation to an article about the staggering rate of star supernovas..

If 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…

A star "lasts" about 10 billion years, so you'd expect about 1 in 10 billion stars to 'die' each year, but only a tiny proportion (the very largest) go supernova. Numbers are huge. Even tiny ratios mean something like 10-100 stars go supernova every single second somewhere in the universe. Sounds a lot? Only about 1 star per galaxy goes supernova per century. A lot of galaxies. Mindblowing.

Wouldn’t the creation dates of stars be clustered around certain points in time. So the supernovas should also happen in groups?

I think there were two separate puzzles where I had identified the correct solution, but the mechanics were so clunky that my attempt failed. Making me waste time exploring elsewhere. Had to consult a guide just to see that I had unknowingly botched the physics. Which is an awful experience for a puzzle game. Especially when the clock is working against you and some of the set pieces require very specific timing to interact with them (where doors are only open for a certain few minutes in a run).

The game is definitely a unique experience, but some of the design elements hamper the experience.
