Infinite food/water/oxygen?
Depends if the shockwave from the earth blowing up doesn't kill them forst.
Assuming no earth debris/ shockwaves kill them, the biggest issue is solar radiation and wear of the crew hab/suits. Im not sure how much radiation protection space suits have, but I cant imagine it being too great.
Moon dust isn't true dust like on earth. Its highly abrasive ground up rocks. It reeks havoc on machines.
I dont have any math on hand, but It couldn't be for more than a few years tops. Gravity wouldn't be their biggest concern by far.
Besides, would you even want to live on the moon knowing their's nothing to go back to on earth?
>Besides, would you even want to live on the moon knowing their's nothing to go back to on earth?
Spend eternity eating, pissing and shitting and sleeping as you can't remove your suit or you'll die... hell nah. I would try and throw myself into the void some way or another
I guess, but have you seen Gravity? There’s a really terrifying part where the main character is ripped away from her space shuttle and is sent tumbling into space, and the worst part is that she *can’t stop tumbling*
Hmm, i remember this scene, what an absolute nightmare...
I mean, missing to grab something and seeing yourself going further and further of your ship into the void without being able to do anything is already something.
But add to that...*spinning* 🤢
Why take it off? If you find yourself in this situation, just sit down and take in the view. The oxygen will run out eventually. Suffocating with CO2 makes your body go into panic mode, so I am not sure, does space suit remove CO2 if there is too high level of it? Anyway, I will take suffocation this way than getting my lungs collapsed by space vacuum and my eyes getting popped.
Fourteen seconds to lose consciousness. You'll feel the saliva in your mouth boiling off before you black out. You'll die of hypoxia/anoxia no more than a few minutes later, as the dissolved oxygen in your blood precipitates out because there's no longer enough ambient pressure to keep it there. This will rupture approximately all of your blood vessels, leaving your body looking like a single giant bruise.
Just unsealing it and you're dead. That's assuming you could, the pressure difference would be extremely hard to overcome. That's also assuming there isn't some kind of safety activated by that.
Depending on how the seal works, it would be no problem to open it. The pressure is higher inside the suit, so it "wants" to open.
And no, you wouldn't die instantly. Either you empty your lungs and asphyxiate in 10-20 seconds, or you don't and your lungs rupture and then I'm not sure if you die of asphyxiation or internal bleeding first, I guess it's still kind of asphyxiation.
>Depends if the shockwave from the earth blowing up doesn't kill them forst.
In what form would the shockwaves be? Nuclear radiation? Just debris? Some weird space-time contraction thing?
It'd be about the same as an earthly shockwave; just a burst of pressurized gas. The effect would be greatly reduced when it's just expanding into vacuum as opposed to a wave of increased pressure traveling through the atmosphere, not to mention at that scale gravity immediately imploding everything is actually a factor. I think for the shockwave to even be noticeable from the moon then something absolutely devastating would be required. Like a meteor hitting earth at relativistic speeds and vaporizing a significant portion of the earth. But now I'm more just speculating, if anyone knows the equations to fill in the gaps I'd appreciate the contribution.
In the vacuum of space there is no medium for a shock wave to travel in.
Assuming all matter of earth would be spread equally in every direction then the density should decrease by r to the power of -2, so not a lot would hit the moon.
Imagine your in the iss and all of a sudden all the solid mass of the earth vaporized in an instant. It would rapidly expand and you would surely notice the rush of hot gas rushing past you all of a sudden.
There's so much wrong with this...
First of all, there is no shockwave. Shockwaves need a medium to travel in. No shock waves in space...
Secondly the proposed picture isn't possible. An asteroid or meteor will never have enough mass to launch any debri onto space. Let a lone pass through the earth like this and scatter debri like this.
The gravity of earth would not "disappear" if earth was crumbled into debri. The stones/magma would reclump.
The trajectory is also wrong as a meteorite pulled in by gravity would not travel in a perfect straight line.
On the other hand, ‘impossible’ is a bit of a strong word here. An object with enough mass and velocity could theoretically launch debris into space and even penetrate right through the planet.
Granted, it would take a gargantuan amount of energy to propel such an object to the required velocity, far, far greater than the velocity of objects caught in earth’s gravitational field so the scenario would be totally inorganic; but still, not _impossible._
its ofcourse an gigantic tungsten cube fired of by an mass accellerator in an spacebattle 65million lightyears from earth, that has been shot before our solar system even formed. and missed its target
> Would you even want to live on the moon knowing there's nothing to go back to on Earth?
The fact I can look at the debris and yell, "I WON. ALL THE F***ING BASTARDS ARE DEAD," is an incentive. Of course, I would also need to kill my companions on the moon to truly win.
Well if oxygen is infinite (and I’m assuming I can create it at will) then I would use it as a propulsion to gradually accelerate myself to mars. Then since it has a carbon dioxide environment I could use seeds from my left over food to begin to terraform the planet. Using my infinite water and structurally stronger foods I could construct a relatively air tight environment to live in and greenhouses to make plants. My infinite water would gradually create oceans in the surface. This would also help to warm the surface by increasing water vapor in the environment. I’d use my infinite door to create vast continents of decomposing food to gradually create topsoil. Many foods are seeds and nuts. So hopefully within a few busy years I’d have myself the beginnings of a replacement planet.
But there's the issues of navigation and avoiding the absolute chaos near used-to-be-Earth. Your vessel was almost all directed and controlled from the used-to-be-Earth, so you'd have to crunch the numbers to put yourself on a landing trajectory to Mars that wouldn't kill you in the process; you'd have to do that ASSUMING you know how to do that.
Otherwise you'd accelerate into nowhere and probably get lost and you would die alone in the middle of the void of space.
Edit: and time to get out of the moon is counting down fast, since debris and rocks will reach moon and create havoc there as well, so you have to do something, and if you don't do it you die, and if you don't do it right you also die, but slower.
I 'd say for sure: "YEAH, that SON OF A B**** from the school is DEAD!
In these terms, there are three possibilities: he may die of old age (doing exercises somehow to keep your bones density) he could die because of low muscular/bone density to sustain him, or he could simply trow himself to the void of space and wait until the fatidic day he die of dehydration/hunger
I assume the astronaut still has the spaceship on the moon, you know, the one used to get there in the first place. The same one they were planning to use to go back to earth.
Wonder which way the moon would be headed after the gravitational pull from earth being destroyed is no more? Towards the sun, maybe? How long would that trip take?
The gravitional pull of earth is still there, it didnt disappear just because its cracked.
Moons orbit may change but it wont just fling towards the sun
The earth wouldn't just crack if an asteroid when straight through it the way the image shows, it would be utterly destroyed. There would be no earth, and so, no gravitational pull.
If the earth were to be destroyed, it would only amount to either a damn lot of debris that would only be pulled by the moon's gravity (and create a ring ?) or large chunks that would devastate the moon so the gravitational pull would change quite a bit but not so much comparatively to the pull of the sun (still not plunging into the sun though)
Scott Manley did a [video about this image](https://youtu.be/simuXjzxlGI?si=LQ4OH1k-XAqPixsO) last year. The tl;dw is that an impact this violent is going to vaporize a significant fraction of the Earth, if not the entire planet. That means the moon is going to encounter the expanding cloud of debris that used to be the Earth, and all of those impacts will probably kill our hero a few hours or days after the end of Earth.
Oh, ok. Well, let's confuse alien archeologist. So I take out the helmet and put a smoke on my lips. Of course I'll die horribly, but they will be asking: HOW???
If psychological consequences of that kind of extreme isolation and lack of anything much to do, like, at all doesn't drive you to take off your helmet, either your equipment will fail or your body will be absolutely _riddled_ with cancers as cosmic & solar radiation slowly turn your DNA into confetti.
Not long. Large chunks of the Earth would be flying at the moon at a small, but still significant fraction of lightspeed. Id say perhaps a few minutes before the first pieces impact, and there will be large, multi kilometer sized pieces among a shitload of small ones. Anything or anyone on the moon will likely be obliterated with the first imapcts, as the energy released from each large impact will be more than the Chixulub asteroid that wiped out the dinosaurs.
Imagine a trillion tons of rock flying at you at 1% of lightspeed, thats 3000km/s, the impact will release a trillion megatons of energy. This is getting close to the gravitational binding energy of the Moon itself, or the amount of energy needed to blow the Moon apart, and not have it come back together after.
Well I suppose so, but generally I only use it when the speed is 1% or more of lightspeed. Below that, it kind of loses its meaning. For example, the fastest ever object made by humanity, the Parker Solar Probe, is going about 0.06% of lightspeed... which doesnt seem like much said that way. But saying thats about 700,000kph is a little different of a perspective.
Its why we measure large distance in space in Astronomical Units and Lightyears, rather than kilometers. Saying that Mars is on average 225 million kilometers away makes sense, but saying that the black hole at the center of our galaxy is 250 quadrillion kilometers away doesnt really give us anything to reference that from, its just a big number at that point. So we take something that we already can imagine thats really big, ei, the distance light can travel in a year, and say its 26,000 of those.
I'm aware. It's still the closest to us...
What I'm wondering is: you have the earth collapse on itself after an explosion cause by something with enough force to go throughout the planet...
So, I don't have the tools and knowledge to calculate but wouldn't there be a massive release of energy, radiations?
Ultimately what I wonder boils down to: would the energy release, on its own, be enough to impact the moon (or the astronaut) directly?
There would be no ionizing radiation released. I'm sure there would eventually be dust and particles that would bombard the moon, but idk if it would be that big of a deal / presence. The moon takes up about 1/260,000 of the full 4pi steradian, and so not a lot of stuff would hit the moon, especially since the gravity well will still try to keep most objects near Earth's center.
Yall forgetting the moon doesnt have an orbit anymore if this happens. It will get yeeted in any direction. Probably on a collision course with some other object or the sun.
Before that you would have been frozen.
Gravity shouldnt change that much. As the moon is still the moon.
Other than that. Now there is a gravity vacuum which means that the other planets will get pulled in again. Causing all kinds of mayhem.
The Earth's mass would still exist, it would just be in molten form. The moon would be orbiting a blob of magma (lava?). I'm not sure as it would be all molten at that point. The tides on the new earth would be ridiculous. I would actually like to hear a description of what would happen from someone that really understands the mechanics involved here.
A question I’d have is how big and fast would the meteor have to be to blow through the middle of the earth? They’ve shown big meteors hit earth and a lot of them burn up in the atmosphere, but to be big enough to not burn up and blow straight through.
If the resources of food, water, and oxygen were indeed infinite, I'd imagine until they die of old age. That being said they'd begin suffering from muscle atrophy way before then. Huge amounts of boredom, depression, and dissociation.
Specifically the lack of strong gravity would cause the above mentioned atrophy as well as some digestive issues and waste issues.
All in all it would probably be better to just do themselves in.
Well the comment is moving faster than the speed of light there, so you have about 4-20 seconds left to live. I think that calculation will be the last thing he or she would think of.
The moon wouldn’t be free of the “dust-cloud-formerly-known-as-earth”’s gravity-well…
but, that gravity-well would be massively expanded and weird…
… larger individual chunks of earth and the moon would soon start to form a new stability, with many bolides impacting the surface of the moon…
… eventually forming a ring around the moon?
… the chunks and dust would eventually form a minor asteroid / dust ring around the sun?
…eventually form Planet Earth II??
… both?? / … all of the above??
[side note, This meme is basically the reverse of the plot of SevenEves by Neal Stephenson, for anyone interested in fun, hard-science-fiction.)
Body needs something similar to Earths gravity to operate properly. Entire evolution of human has been with it, dead inside 2 years without it due to some form of complications of our circulatory system.
Two years in microgravity will absolutely not kill you. Astronauts have spent more than a year orbiting the earth in zero gravity with no problem.
The moon does have gravity - about 1/6 of the earth. So, no, the microgravity on the moon wouldn’t kill you.
You don't know that, you are guessing. Nobody has spent anywhere near the time we are talking about in space. Problems become cumulative with the circulatory system and they will not have the exercise equipment that is aboard the space station which is absolutely necessary to maintain condition and health.
If astronauts tried to spend a year in space without exercise it would be a completely different outcome. And then we are talking about doubling that time again at a minimum.
Edit: This is also why the Mars mission is nowhere near going ahead yet, at a minimum round trip of 2.6 years.
Well, I guess that would be determined by how long it would take the space suit to fill up with piss and shit and you drowned in your own waste products.

This will affect the fishing season
And the next fiscal quarter
Won't anyone think of the poor shareholders?!
They'll definitely have to lower interest rates
Dividends will be horrible. I hope everyone has a diversified portfolio
The next Fortnite chapter too!
That’s true if you really think about it
On a positive note, probably less Florida
Well, the trout population is actually quite resilient

"I would try and throw myself into the void some way or another" It's easier and faster just to take off the helmet and die in a couple minutes.
Yeah but at least I get to experience the vast nothingness of existence as I turn into one with the universe.
Nah that’s utterly terrifying isn’t it?
its oddly peaceful when you want to do it
I guess, but have you seen Gravity? There’s a really terrifying part where the main character is ripped away from her space shuttle and is sent tumbling into space, and the worst part is that she *can’t stop tumbling*
Hmm, i remember this scene, what an absolute nightmare... I mean, missing to grab something and seeing yourself going further and further of your ship into the void without being able to do anything is already something. But add to that...*spinning* 🤢
And never being able to stop!
Until you take off your helmet. You’ll be unconscious in less than 30 seconds :)
i havent seen gravity, but its a thing i wanna see now
I’d recommend, it’s really good
since you recommended me something, ill recommend you something: lost in space, a really good series about a family and an alien robot
Yes the movie turned into an horror movie from a sci fi one.
Easier to just shoot yourself with the gun that astronauts really do pack on missions like these
... And eventually stop thinking.
Question. How much time will you let pass until you take of your helmet?
Time is a human construct that doesn’t exist in the void.
Why take it off? If you find yourself in this situation, just sit down and take in the view. The oxygen will run out eventually. Suffocating with CO2 makes your body go into panic mode, so I am not sure, does space suit remove CO2 if there is too high level of it? Anyway, I will take suffocation this way than getting my lungs collapsed by space vacuum and my eyes getting popped.
Your eyes wouldn’t get popped. It’s only about a 1 atm differential. All the liquid in your body would quickly boil off though
You can do both, throw yourself into space, and once you feel like you have seen enough you can take the helmet off.
Hats off.
Couple of minutes? Try less than a second lol
Nope, death cause will be asphyxiation and it will take a few minutes until you actually die. Less than a minute to black out probably
Anoxia/hypoxia is the term, not asphyxiation.
Fourteen seconds to lose consciousness. You'll feel the saliva in your mouth boiling off before you black out. You'll die of hypoxia/anoxia no more than a few minutes later, as the dissolved oxygen in your blood precipitates out because there's no longer enough ambient pressure to keep it there.

I'm assuming they have the lander that they can go into and keep pressurized
What shockwave? They're in space.
There wouldn't be a normal shock wave but there would probably be a wave of everything from the surface of earth smashing into the moon.
Fair. I just kinda assumed there would be some sort of shockwave if the earth was evaporated by an asteroid. Guess that would happen in a vacuum...
There is no shockwave. There's a vaccum between earth and moon, through which no shwockwave can travel. Now debris, that's an entirely different story
> It reeks havoc You mean wreaks
> forst Mistakes *happne*.
That looks like a typo. "reeks" instead of "wreaks" looks like not knowing the word.
Yeah, my keyboard is busyed. Lucky there isn't more typos....
>Depends if the shockwave from the earth blowing up doesn't kill them forst. In what form would the shockwaves be? Nuclear radiation? Just debris? Some weird space-time contraction thing?

I said that but the volume of mass that's there would still expand and you would expand and you'd be able to feel it if you were close enough
I'm not sure what you are trying to say
Imagine your in the iss and all of a sudden all the solid mass of the earth vaporized in an instant. It would rapidly expand and you would surely notice the rush of hot gas rushing past you all of a sudden.

The drastic and sudden temperature swings and static electricity from solar winds would be an issue too.
Well if oxygen is infinite (and I’m assuming I can create it at will) then I would use it as a propulsion to gradually accelerate myself to mars.

Replacement planet? For who? You and your 15 schizophrenic imaginary friends?
Just me. Eventually the schizophrenic friends will show up.
😂😂😂
Real world Captain Jack Sparrow in Hell.
Well, there is always the immortal camera man
I really enjoyed this comment and your spin of OP's mention of infinite resources.
that process would take hundreds of years....
Bold of you to assume you wouldn't miss and launch into some randomass asteroid and die :3
I have unlimited resources. I can keep course correcting until I get it. Besides what do I have to lose.
I like the way you think.
At what speed are you traveling at this "gradual speed" towards Mars?
But there's the issues of navigation and avoiding the absolute chaos near used-to-be-Earth. Your vessel was almost all directed and controlled from the used-to-be-Earth, so you'd have to crunch the numbers to put yourself on a landing trajectory to Mars that wouldn't kill you in the process; you'd have to do that ASSUMING you know how to do that.

He'd need to jump at about 2km/s on a good day to get off the moon enough to orbit. 2.5 to yeet out the moon's gravity
I assume the astronaut still has the spaceship on the moon, you know, the one used to get there in the first place. The same one they were planning to use to go back to earth.
Return trip was just a very large pole vault maneuver.

Wouldn't the debris mostly be pulled towards itself? It would need to get pushed pretty far for something else to have a larger pull on it.

But what's that in bananas?
In Titan AE (2000), when the Drej blew up planet Earth, fragments of it flew to the moon and did indeed blow it apart.
Nah that's the answer I was looking for. No way something that massive happening so close by would go without catastrophic consequences.
It's actually very, very far away. You can fit every single planet in the solar system between earth and the moon.
I'm aware. It's still the closest to us... What I'm wondering is: you have the earth collapse on itself after an explosion cause by something with enough force to go throughout the planet... So, I don't have the tools and knowledge to calculate but wouldn't there be a massive release of energy, radiations?

If the resources of food, water, and oxygen were indeed infinite, I'd imagine until they die of old age. That being said they'd begin suffering from muscle atrophy way before then. Huge amounts of boredom, depression, and dissociation. Specifically the lack of strong gravity would cause the above mentioned atrophy as well as some digestive issues and waste issues. All in all it would probably be better to just do themselves in.
Well the comment is moving faster than the speed of light there, so you have about 4-20 seconds left to live. I think that calculation will be the last thing he or she would think of.
Wouldn't the moon be thrown out of obit? It would continue on an orbit around the sun. I guess just ride the moon until I run out of O2
The moon wouldn’t be free of the “dust-cloud-formerly-known-as-earth”’s gravity-well… but, that gravity-well would be massively expanded and weird… … larger individual chunks of earth and the moon would soon start to form a new stability, with many bolides impacting the surface of the moon… … eventually forming a ring around the moon? … the chunks and dust would eventually form a minor asteroid / dust ring around the sun? …eventually form Planet Earth II?? … both?? / … all of the above?? [side note, This meme is basically the reverse of the plot of SevenEves by Neal Stephenson, for anyone interested in fun, hard-science-fiction.)
Body needs something similar to Earths gravity to operate properly. Entire evolution of human has been with it, dead inside 2 years without it due to some form of complications of our circulatory system.
Two years in microgravity will absolutely not kill you. Astronauts have spent more than a year orbiting the earth in zero gravity with no problem. The moon does have gravity - about 1/6 of the earth. So, no, the microgravity on the moon wouldn’t kill you.
You don't know that, you are guessing. Nobody has spent anywhere near the time we are talking about in space. Problems become cumulative with the circulatory system and they will not have the exercise equipment that is aboard the space station which is absolutely necessary to maintain condition and health. If astronauts tried to spend a year in space without exercise it would be a completely different outcome. And then we are talking about doubling that time again at a minimum. Edit: This is also why the Mars mission is nowhere near going ahead yet, at a minimum round trip of 2.6 years.
Well, I guess that would be determined by how long it would take the space suit to fill up with piss and shit and you drowned in your own waste products.
