Yay! I can finally take the eternal nap!
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.
I’m your enemy now
I’m your enemy now. I will exhaust you.
Arch nemesis… only Arch users have those.
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’ll tip my Fedora to that.
And my axe
Oh…
…
…
…fuck.
One small uh-oh for a man, one giant extinction event for mankind.
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…
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.
Honestly… It looks like he will have a lot of downtime now.
“Tja…”
But what about the stock market?
To the moon
I’m Polish, so the same thing I say in any situation: “Kurwa”.
Such a beautiful language.
It means whore.
Literally yes, But it’s more of an f- bomb
Oh, didn’t know that meaning 😁.
It’s a slow death for me, but a fast death for mankind.
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.
Seveneves
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.
“somebody is fucking with me”
The Earth is way too close, and I don’t think a meteor strike on the earth, no matter how energetic, would look like a bullet going through an apple.
You assume this is a meteor strike and not some type of planet killing weapon
Or a moon late for work.
That’s no moon.
Kinetic kill vehicle.
Maybe a piece of very dense matter (neutronium ?), at very high speed (relativistic) could do that ?
I think any matter going fast enough would do that. In the fast going thing’s perspective the earth would basically be just a thin membrane.
Yeah but the projectile itself would also liquefy. Maybe if it was something super dense.
that’s basically chemistry. At relativistic speeds the electrons of the projectile don’t have play a significant role. It’s going to be atomic nuclei hitting atomic nuclei and the time it takes to go through the earth is like two microseconds for the projectile going at ( 1 - 10^-9 ) c. Even that, I suppose, is too long for the particle beam to scatter momentum from fusing with other particles, creating gamma rays, creating exotic particles etc. But we could just always go even closer to c?
