“don’t panic”
Oh no… My stuff!
The economy!
Seveneves
One small uh-oh for a man, one giant extinction event for mankind.
silently take delight in knowing all my enemies are dead
I mean you’ve got to look for positives, right?
Do people have enemies? That seems exhausting.
Arch nemesis… only Arch users have those.
I’ll tip my Fedora to that.
And my axe
But I use blendOS? What does that mean?
You’re your own worst enemy 🤷…
Thats the curse i guess of being the real chimera of os’s.
I’m your enemy now
I’m your enemy now. I will exhaust you.
Oh…
…
…
…fuck.
“Tja…”
The amount of energy it would take to punch a hole through the Earth would probably be enough to kill you from the moon.
Like just in terms of “bullets” ejected?
probably radiation:
that kind of impact is gonna tear apart a lot of atoms and the energies involved would create high temperature plasma; basically a very big fusion bomb…
But what about the stock market?
To the moon
From the looks of it the astronaut was just out of the lunar grocery store starting to walk home for some dinner and down time.
That’s not how planetary collisions work.
Earth’s core is a solid ball of iron-nickel alloy as hot as the surface of the sun. Not even a huge asteroid could just go through it and come out the other side.
The ball on the bottom right, is the earth’s core leaving.
BTW, the book Seveneves is worth a read/listen. It covers a scenario of something very very dense passing through the moon.
I started that book, because I was super interested in the concept, and I couldn’t continue after a few chapters. The way he writes women seemed very poor to me.
I like the idea that it hit the core and knocked it out the other side while remaining in place like that one executive desk toy thing. Newton’s cradle? is that what that thing is called.
Someone get Randall Monroe on this image, he’d do the math.
The thing that strikes me…the object hit the earth dead on, on the sunlit side, so the object would have come right out of the Sun or slightly behind. Like it looks like it was about 2 PM where the object hit. So the object would have barely missed the Sun…yesterday or so at the speed it would have to be moving to splat the Earth like a bullet through a melon.
I think to hit that hard it would need to be moving at a large fraction of the speed of light, in which case there would be a tremendous amount of nuclear fusion. Like, probably an exaton blast.
The thing is Randall already kind of did something like this in his “What-if?” which talked about a diamond meteor hitting the earth…
And basically it boils down to: Either Galileo/Newton/whoever was the smart fuck that discovered it was right and the meteor would only create a crater roughly as deep as it was itself. (This if it could touch the core it would be at least the same size as the earth and the picture would look different)
Or it would be going fast enough to ignore most of all that classical physics stuff, phase through most solid material and blow apart every piece of the earth because it would have enough energy to completely overcome the gravitational force holding everything to everything else here on earth.
(Now granted, those were the two extremes and there might just be a perfect balance in between, but I’m sure as hell not going to look for it! At the very least because getting funding for the experiments is seriously difficult for some reason…)
It’s a slow death for me, but a fast death for mankind.
I think at that point you would just take of the helmet.
My thought exactly
Is it bad that I would possibly give it a bit?
Like, I’m fucked either way. Who knows, maybe I’ll make it for another sleep cycle, and the last thing I’ll see will be those fragments further scattered. Something pretty, as the liquid in my eyes begins to rapidly boil.
I’d be out there until I was floating in a most peculiar way.
Death by starvation isn’t this person’s fate, is it? I wouldn’t think it would take more than a few days or maybe even hours for the debris to land. I’d just sit there in existential horror while trying enjoying the view, waiting to get taken out instantly by some giant chunk of the mantle landing on my head. Of course that’s mostly because I’d be too afraid of the pain to take off my helmet.
Actually, can you even take one of those helmets off without equalized air pressure or is there a mechanical safety that locks it? If there’s a separate nitrogen tank and you have control over the mixture, just turning off the oxygen would be the way to go.
So, uh, is it a bad sign that I put that much thought into hypothetical ways to kms on the moon?
In this scenario, it would probably be the rational path forward, as you’re in a situation where you’re guaranteed to die either way. So why not make your death as painless as possible?
Depending on which mission this is it could be a lot shorter. The original PLSS backpacks had a two hour air supply. The LM was powered by batteries and could only sustain life for 48-72 hours depending on configuration. If they launch and rendezvous with the orbiting CSM, they can extend their survival by several days, but there’s functionally nowhere to go.
For my money the best way to go is probably in the suit, outside, and let the oxygen run out while the carbon dioxide scrubbers are still working.
Now I’m not some fancy science-man, but I do reckon that an impact of that magnitude would propel massive chunks of Earth debris in every direction at incredible speeds. Odds seem fairly well even that you’d get your own little impact death pretty well soon after.
eh…given the distance and the weird orbits it’s gonna take for the debris to actually hit…a few days probably?
couple of days for the bombardment to hit the surface, and then it’s a game of statistics how long it takes for a direct hit or secondary ejecta to hit your landing site/base.
probably a better idea to take all the fun pills all at once than to wait for that…
actually, you can probably simulate this rather well in universe sandbox! ;)
Yeah no that thing impacted with a lot of speed. Like >1% of the speed of light to go through the entire earth like this. Consequently, the debris is moving very fast as well.
the ejecta themselves would definitely pose a danger, but air supply running out would probably kill you before they impact the moon.
the distance between earth and moon is already significant, the angle shown in the picture is pointing away from the moon, most of the mass would stay in the same place due to gravity pulling everything back together, the orbital path the debris has to take in order to impact is gonna take multiple orbits for most of the debris, and only a fraction will impact on the site pictured.
still dangerous, but not as immediately as one would think.
the only significant projectiles would be a small portion of the debris just off-center from the exit crater (the sort of “cork” shooting out):
- some of that mass would be going the right way
- some of it will be going the right speed to arrive in time before air runs out
- and some of that is gonna rain down roughly in the area the picture was taken at
so it would only be a fraction of a fraction of a fraction that even has a chance of coming down onto the astronaut pictured, but that’s still gonna be enough to be dangerous.
it’s also gonna take a couple days to arrive most likely; the debris is not gonna come straight at the moon, because by the time it makes it there, the moon would have moved and it would miss.
a vanishingly small fraction will move fast enough to impact on a (mostly) direct trajectory. those impactors will still take at least a couple hours, even at close to relativistic speeds, and it’ll consist almost entirely of dust and tiny micro meteorites. the fast movers have to be tiny, because anything larger would be torn apart by the acceleration.
(…actually I’m not sure any material apart from more exotic states of matter like nuclear pasta (which doesn’t exist on earth. yes, that’s an actual technical term) could even theoretically be accelerated to a significant fraction of c in the presumably less than a few seconds pictured above without being torn apart at the atomic level…and dense material experiences greater gravitational pull, so it would have a harder time reaching the moon…)
in order to impact, the vast majority of the debris would need to move on parabolic trajectories, and most of those will take multiple orbits in order to impact.
during those orbits, most debris will be pulled back onto earth, or in orbit around earth, since it’s gravitational pull is so much greater than the moons. add another fraction to the ones above ;)
we’re still missing a bunch of considerations, but I’m gonna stop here.
point is: as pictured above (apart from the impactor being impossibly dense) the danger to someone on the moon is mostly manageable and secondary to the danger of supplies running out.
If you’re lucky.
Finally!
Well… shit.
Houston, we have a problem
