Hes just spergin out like a boss, its hilarious

stop making threads about this reddit fuckhead. it's not science or math

Mainly autism.

He tried to reach out and was insulted for it. To him, that's two insults against him, so his insult was verbally stronger than that of the accuser to compensate. Unfortunately, in real life, you can't just add up the severities of insults and hope they balance out, but in his autistic mind they can and he felt justified in the heat of the moment, plus I bet he's broken up with Grimes or something.

>>9871755
idk but it's funny watching his groupies realize he's some kind of moron. We're reaching peak Tesla

>>9871760
He acidentally named the Jew one time and the media is ravenous now

>>9871787
Doesn't matter. They are expendable, the God Emperor is not.

>>9871792
I know there's a good chance he is right in his accusation.

My view is that although he shouldn't have said it, he shouldn't be lynched by the mob for saying this. I think he really is mildly autistic and he can't make judgements about what is acceptable to say, but at the same time he's intelligent and going to get us to Mars so if anyone does anything to him they are entirely responsible for ruining that dream. Things are made doubly hard by the fact that his own mob are now undoubtedly trying to lynch the diver.

>>9871800
i think he just literally doesn't give a shit, he's a fucking billionaire

>>9871800
>mildly autistic
That's putting it mildly.

>>9871755
Seeing how autistic this guy is I'm starting to doubt the wisdom of going to live on Mars in the first place. What if colonising Mars is just his autistic obsession and in fact it's just a frozen shithole with nothing to recommend it?

>>9871805
I mean to say he isn't the vegetable kind of autist

>>9871807
We have a pretty good idea of what it's like, and we have a pretty good idea of how boring it will be. But building a self sustaining colony on Mars is invaluable to preserving human civilisation, without a doubt.

What "citation"? It's a jello baby factory with an average temp of -80 degrees with barely any ressources on it, how the fuck is that supposed to be the safe haven for mankind?

>>9871880
Oh yeah, almost forget that there is NO BREATHABLE AIR there. Man, such a nice place to live!

>>9871877
Mars is a hue asteroid disguised as a planet. The gravity is so low you can't even walk properly. 0.5g would be ok, but 0.38g is too low

>he's going to make divers go through a cave where a diver died just to prove a point about his meme submarine
>probably won't even work because a guy who has been in that cave says there's no way to get it through

>>9871880
it's the most suitable place we've got. We either make it work or we don't have a backup at all.

Give it a couple of hundred years or so, self-replicating robots (it must be possible to make them since humans are self-replicating robots, we just need to figure out how to put the atoms together in the right way) will facilitate the development of liveable habitats on Mars on a large scale and it will be totally doable.

Even with current technology and sufficient will it may be possible to do some initial groundwork like excavation and basic structures.

>>9871887

>>9871884
I bet the diver guy is sweating bullets right now. He knows he'll get that sub through.

>>9871891

>>9871887
pro tip: If you need "Self-replicating" robots to make a place habitable, that place is not habitable.

There is absoluetely nothing that could happen on earth that would make it as bad as Mars.

>"After facing backlash for the comment, the billionaire added: “Bet ya a signed dollar it’s true.”
You lot are just pussies, Elon is the hero we all need.

>>9871887
nothing against the utility of space exploration, but it really doesn't feel like any sort of colony we can build in the next 100 years will let mankind recover from earth being smashed by an asteroid

>>9871894
big fuggn asteroid

>>9871887
No amount of terraforming can

*increase the gravity of the planet in a meaningful way
* increase the atmosphere of the planet in a meaningful way so that the temperature rises to >0 degrees celsius and make the air breathable, because the planet is simply too small to hold onto an atmosphere that thick, and we are not even talking about the impossible task of "importing" insane amounts of atmosphere gases from other places of the solar system


So Mars, even after millenias of terraforming, will never be able to hold more than a few hundred thousand peoples living in habitats, barely going outside and if they do, they need to wear basically space suits. This is not a "back-up". This is an unnecessary strain on human economy.

>>9871894
nuclear war

>>9871904
even after a nuclear war, the radiation on earth would be less than it is on Mars.

>>9871898
>>9871901
Oh yeah, the last big asteroid that hit earth really completely sterilised the planet and made it completely unhabitable.

>>9871906
you're forgetting about all the dying and stuff

>>9871913
you seem to underestimate how hostile mars is to life. a nuclear wasteland looks like garden eden next to mars.

>pedos itt arguing against space expansion

>>9871903
I don't see Mars as a planet which can support humans, rather as a giant heap of resources (basically a free spaceship which is spatially separated from Earth in case of disaster). It is not going to be easy to make it self-sustaining but it's about the easiest we have in our solar system (the atoms are there, we just need to find a way of extracting them efficiently). Lots of water to go under the bridge in terms of ISRU but there's no other option, and if a billionaire wants to spend his money exploring the technology to do so then so be it.

>>9871910
lol, you wouldn't be here if there really was one which sterilised the planet. That was low-hanging fruit lad, you need to logic more

>>9871914
except for all the dying and stuff that precedes the wasteland

>>9871916
Mars colony is retarded, even if you wanted to colonise space building habitats in near-earth space or on the moon makes more sense. There is absoluetely no reason whatsoever to colonise Mars and it will absoluetely never happen.

>>9871807
Broken clock, twice a day.
Some offworld colonies would be a good idea.

>>9871919
You do know though that Mars is a COMPLETELY dead planet, and no amount of nuclear bombs will ever completely sterilise earth?

>>9871918
Earth crashed with a literal planet once and it didnt sterilise it.

>>9871920
Mars has about the same delta v as the Moon to get to due to the atmosphere for aerobraking, and as I say it is spatially separated from the Earth (important if it is to be a backup).

Mars also has the atmosphere as a ship fuel resource. That's one big ISRU problem solved already by the Sabatier process.

>>9871923
Yeah you're missing the point. If Earth gets nuked you die. If you're on Mars, you don't.

>>9871923
They don't have to completely sterilize earth to end civilization. Even a small exchange over land would darken the skies for years causing mass starvation.

>>9871923
>Earth crashed with a literal planet once and it didnt sterilise it.

LAD! Please try harder, that was the very primordial Earth, before fossil records begin. Life started after, or was brought there after. Also,
>thinking higher life forms would stand a chance of surviving the collision of two planets

>>9871923
>no amount of nuclear bombs will ever completely sterilise earth?
M8 if America and Russia just decided to detonate all of their nukes at the same time, without even firing them at any location the fallout would destroy the ecosystem to the point where human life would be impossible

>>9871926
That's not the point being made. People are saying Mars is a back-up. Even if a nuclear war breaks out on earth, humanity will survive and have a better planet to live on than "Marsians".

>>9871927
In which case it would STILL be better here than on Mars.

>>9871930
Yes, after the crash life was still able to develop on earth. On Mars, not so much.

>>9871935
It absoluetely wouldnt you literal brainlet.

>>9871937
Nigga you missing the point.
There's only one here.
Let's make a backup. A two. Just in case.

>>9871937
That is the point being made. If a full scale nuclear war broke out, all humanity could very well go extinct on Earth.

If we're established on Mars, we would not.

>>9871940
You dont seem to understand Mars is not a back-up. Back-up for what? There is no scenario of a catastrophe that can happen on earth that would make Mars a more habitable place than Earth. Do you understand this? Mars is not a back-up.

>>9871945
We can build domes in earth gravity can't we?

>>9871944
> If a full scale nuclear war broke out, all humanity could very well go extinct on Earth.


lol, no. Not even the current state of nationhoods would break apart, because every developed nation has nuclear bunkers that can house millions of people for several decades.

>>9871807
As far as autistic obsessions go, he chose well.

>>9871947
You dont need domes on earth, because this little thing called ATMOSPHERE.

>>9871951
Gas isn't actually very smart.
I say sir, I do believe we can trap it in cleverly designed enclosures!

>>9871937
>Yes, after the crash life was still able to develop on earth.
after the surface, transformed into a sea of molten lava, cooled down, yes. If that that happens to Earth again and we have no sustained presence on Mars, it's Goodnight Vienna for human life.

>>9871939
It would block out the sun for years you retard

>>9871955
Even then, with the surface being molten lava, earth was a better place to live on for humans than Mars. Do you understand this?

>>9871956
Almost like a big dust storm on Mars huh.

>>9871959
I'm not the anon you're talking to about colonizing mars. He's just as retarded

>>9871945
what if a GRB hit earth?

>>9871958
and now your logic has completely broken down. What are you smoking? In what reality is a sea of molten lava more habitable than subterranean habitats that only need to be heated from and ambient temperature of about -20C?

>>9871966
It would probably cause a mass extinction event, but not completely sterilise earth.

>>9871966
not that guy (I think Mars is a useful backup) but a quick search indicates that GRBs have quite wide beams; one which hits Earth would probably hit Mars too. That being said, the extinction event in the Ordivician has been attributed to a GRB, but the cause of death was mainly due to the chemical effect on the atmosphere, rather than simply burning one side of the planet. This means that subterranean society would probably be safe.

>inb4 just build a subterranean society on Earth

Earth will always rely on its surface to sustain society. If the surface dies, civilisation on Earth is fucked.

>>9871958
What's so bad about expanding out into our own solar system? Why should we not do that?
Will it require a technological sophistication unknown to the average person today? Yea.
Will it be radically different from the way people live now? Yea.
"Change is scary" isn't a reason to not do something.

>>9871807
Retard. He doesn't give a shit about colonising Mars. He's a businessman, it's just bullshit to garner funding and reddit worship. His """submarine""" bullshit recently was just a publicity stunt.

>>9871948

I hope the diver sues him for calling him a pedo. If Musk has proofs then show them. If not you are a liar and you have to pay for damaging the honor of that man.

>>9871807
It IS a frozen shithole with nothing on it. Musk is, like any other company, hyping up his shit. Like BP saying they "power the world". You'd be better off launching rockets directly to hospitals planets in other systems. But musk doesn't make ftl devices so now he's trying to convince people to go to Mars.

>>9872014

What do you want from Mars atmosphere? It is fantastically thin and composed of almost only CO2, a small amount of nitrogen and trace amounts of other gases.

>>9872021
Telling somebody he can put his "mini-submarine" in his ass is not the same as accusing somebody of commiting a serious crime. Musk will definetely have to pay for this.

>>9871926
Actually nuclear missiles would only target major powers. And specifically their urban or industrial regions. They don't the capacity or desire to elimate nations like Singapore or Argentina.

Demonstrably, no. The amount of energy you would need, even strategically placed, to cause total extinction for humans via nuclear detonations is orders of magnitude more than we have available. Nukemap is actually fairly accurate.

>>9872075

>what is our moon

>Venus
literally hell incarnate (acidic, hot enough to melt lead, crushing pressure), shows how much you know

>any one of the random moons
The only ones of any size are around the outer planets, which suffer from lack of sunlight for power, and many are their own special kind of hell (Io is a volcano planet, the inner moons of Jupiter are horribly irradiated by the radiation belts)

Mars is indisputably the best body in the solar system for establishing a colony. There are some arguments for establishing a ship colony in the asteroid belt though.

>>9872075
How the hell are we supposed to set down on the surface of Venus? We'd have to do the high altitude balloon cities thing.

https://en.wikipedia.org/wiki/Bombing_of_Tokyo
Stop pontificating about topics you have no salient knowledge of. It takes a relatively small nuclear exchange to end our civilization, it takes an unimaginable exchange to cause extinction. The estimate for the K-pg extinction event was 420 zeta joules or 100 terratonnes of TNT, which only resulted in extinction for approximately 75% of the species on earth.

>what is venus

>The average temperature on Venus is 864 degrees Fahrenheit (462 degrees Celsius). Temperature changes slightly traveling through the atmosphere, growing cooler farther away from the surface. Lead would melt on the surface of the planet, where the temperature is around 872 F (467 C).

Its also vastly closer, and by your own argument for "resources" therefore superior.

as above, all those failure modes. Plus just living there is one thing, it is another thing to get down to the surface to mine the resources (which is sort of the point, otherwise you may as well just live in a space ship in and not bother with the risk of entering Venus's gravity well). I can't see any reasonable way of getting large mining equipment down to the Venusian surface, and then lugging it back up to your airship colonies with some flying contrivance.

>>9872154
Compared to terraforming Mars? Literally everything.

>>9872043
Impractically slow, untested and expensive.
>>9872056
>living underground
>heat transfer equations
The more moderate temperatures underground would just result in being more consistently below 0C. I assume you mean heating from the Martian core. No one really knows how hot it is, but if we assume the 25C per km of earth (very generous because our core is much more energetic), and using the average Martian surface temp of - 55C, and assuming a 20C for crops to grow, you'd need to dig 3 kilometers underground and excavate a living area. Mind you, the deepest place a human can go in earth is about the same depth, this mine took decades to drill. And every kg of mining equipment sent will cost more than 45k just in transfer costs, using SpaceX's untested (and given Musk's consistent exaggeration) generous estimate.

>doesn't matter
Yes, it does, because if you're perpetually confined to your colonies, self sustainment is not possible. Minerals, ores, rare earths. All the shit you at least need to manufacture replacement parts. I'd like to see an astronaut even pick up a rock ten clicks away and bring it back on Mars. It'd take hours.

>aerobraking
Why the hell do you want to aerobrake? Do you enjoy losing energy?

>methane rocket propellant
Again, infinitely easier to manufacture on Earth

>gravity well
So is Mars. And while Mars has weaker gravity, it also has 0% of the vastly complicated industry needed to manufacture methane on an industrial scale and send it to orbit.

>>9872178
Terraforming Mars would be more complicated as you'd have to boil the volatiles out of the ground and it could take centuries to settle.

>>9872180
>heat
the point is that the variation is smoothed out. It will still be cold and heating will be required, but at least you won't have to contend with anything extreme.

>carbon/water cycle
Just keep expanding your rabbit warrens and saving all of your waste, can't see it being that difficult - not entirely sure of the point you're making here

>aerobraking
Landing on the moon requires you to fire your engines much more than landing on Mars. aerobraking bleeds off that interplanetary velocity for free, something you don't get with the moon

>methane propellant
yes, but then it would be on Earth. It's no good stuck in our gravity well.

>Gravity well
the Martian gravity well is four times less deep than that of Earth (half the escape velocity). Since methane ISRU is instrumental to SpaceX's plans, we can only assume it is somewhat feasible.

I don't want to overplay the importance of methane though. The point about colonisation is staying there so it's a smaller issue, getting people back off Mars.

>>9872187
>give it a rotation and move its orbit further out. Maybe even give it a moon.
Do you even realize how ridiculously difficult this is? Many orders of magnitudes beyond our technology.

Meanwhile Mars only needs to be warmed up enough to start a runaway greenhouse effect, which should provide enough atmosphere pressure to maintain water in a liquid form.

>>9872197
>runaway greenhouse effect
But that's still just a hypothesis

>>9872180
>Why the hell do you want to aerobrake? Do you enjoy losing energy?
...yes?

>>9872200
A substantiated hypothesis.

>>9872197
crash Phobos and Deimos into the poles for a bit of a laugh

>>9872207
Do you realize how much energy you would need? We couldn't deorbit Phobos if we wanted to. Not in a 1000 years with current technology. You'd need anti-matter engines.

>>9872213
yeah I'm just being silly

I wonder though - how much mass would be left of the two moons if we ejected it from their surfaces with our best technology to change their inclinations?

>>9872213
Nah. Solar mirrors to concentrate the light onto one side, vapourising the crust to act as reaction matter.

>>9872197
If you would put all the carbon there is on Mars into the atmosphere you would heat it up by around 10 degrees, so from around -80 to -70 average temp. There are barely any other elements that can be used as greenhouse gases on Mars, so it's not really possible to create a runaway greenhouse effect. Also, due to Mars' low gravity a thick atmosphere would be lost again so even if you took the elements from elsewhere it's not going to work.

>>9872224
Enjoy waiting for the next 1000 years or so.
