Astronomer on a planet just a little too close: “This is a cool way to die”

Balthazar ,

Pretty sure the curve should turn up on the right side at some point.

NegativeInf ,

Nah, happiness should asymptotically approach 0 happiness as distance increases, due to decreased brightness. Tho, I guess there could be a discontinuity at the crossover point of where we can no longer observe it and the happiness we can extract from understanding that there are those so far away we can never see them?

kunaltyagi ,

At some distance, we can no longer see the stars or even the galaxy. A supernova will allow us to see in really distant past, maybe at the first generation with some really good lensing.

Think ereandel but older

OhmsLawn ,

There’s something to be said for very early supernovae. I’m sure they’d all be giddy for something beyond 13 billion light-years (or whatever that works out to in red shift).

If we somehow discovered a supernova (or anything, really) beyond the observable universe, I believe the astronomers would be very very happy.

Wikipedia (Near-Earth Supernova) says that a 25 ly away supernova would wipe out half the ozone layer so that’s probably the lower bound for what we want

Geez, how many stars do we have that close to us?

elvith , (edited )

So far, we know of 131 stars objects

None. Space is big, and stars that can potentially supernova are rare. …m.wikipedia.org/…/List_of_supernova_candidates

hperrin ,

Your answer is a little misleading. I think you meant there are several stars that close to us, but none that can go supernova.

whocares314 ,

That’s fair. It’s also a little misleading because there are other cosmic events that could happen that are both closer to us and potentially further away, and have in the past. I wouldn’t say we are immune from the hazards of space but my comment could have been construed that way.

That’s disappointing

chepox ,

I like this one… Because I understood it!!! Plus it’s funny.

When I don't understand them, I'll sometimes check out explainxkcd.com .
