Well boys looks like jello babies are off the menu:
can't link a goddamn nature article because 4chan's spam detection is stupid so google "Inventory of CO2 available for terraforming Mars"

TL;DR there just isn't enough extractable CO2 to terraform Mars

Inb4 just heat up regolith to release adsorbed CO2. Authors considered that, you have to process regolith 100 m deep over the ENTIRE SURFACE OF MARS to get enough. Oh and if you can't keep it hot the CO2 get readsorbed. Sure you could use a big fucking lense to heat up all of mars, but it'd take 10000 years for the heat to penetrate all the way.
Inb4 asteroids, to make it work you'd have to bombard the ENTIRE SURFACE OF MARS. We cannot do that with the tech we have today.

My personal favorite idea for mars is excavating the core and building a few million orbital cylinders in a tessellating matrix of dodecahedrons, and then putting 0.3atm of air inside between the cylinders so that we we can have large scale zero g recreation.
But normies are retarded faggots.

uhhhhhhhhhhhhhhh, what? How the fuck are you going to get stuff to orbit in a tesselating dodecahedron? And if you say anything resembling a dyson sphere, we don't have the materials to do that. Oh and a big sphere around a planet is not stable.

Just nuke it bro. Once you get tsar bomb level shit you can scale up real quick. There's no limit to how powerful you can make a multi stage fusion bomb.

If we turn the surface to magma you can bet the CO2 will all come out. And 50 years later we colonize.

nigga, the original dyson sphere was a swarm of habitats and solar collectors, it was never a full blown shell

We don't know how to make nuclear weapons that big and where the hell are you getting all the fissile material to do that because last time I checked H-bombs still need fissile material.
>>50 years later
you need to heat more or less the entire planet 100 meters deep. If the entire surface is lava it's gonna take a damn long time to cool.

uhhhhh... ok, good luck excavating an entire planetary core, much less just reaching one.

Were these Model 3'she was talking about actually abominations? My old boss, Robert Garrett, who sure does remind me of Rick Gates, drove a Tesla. He was really into Tesla, and named-dropped Tesla in the office a lot.

That was my semen in the freezer in Manafort's locker, right? Manafort and Gates sure do remind me of two people, the latter I met just after Helene and Joe hit me that fraud affidavit. After, they had me temporarily enslaved at the insane asylum, I relented in my protest and got a job. Robert was my boss. We were a credit card company, and he seemed real self-satisfied on the day that AMEX exec died on the flight from Japan. When I told Robert, via Twitter, that something weird had happened after police arrested me and brought me to the jail, pic related, where I was thrown in the padded room with a hole in the flood and blood and doodoo on the walls. At work, he was like, "Oh!! That's what that crazy thing was that weekend before you started working here!?!?"

excavation costs increase exponentially with depth. No heat is not the reason for this:

he was sitting over there by his desk like this. he was sitting next to this desk, not at it, like this, and it was the only time I ever saw him sitting there, or like this, he was a pretty modest guy in his body language.

Before that, one professional task I did was to examine a problem in some international currency thing with the international credit card transactions. I was asking Robert about it, and he showed me what it was, and I saw that it said 1 Yen was equal to 100 Dollars but actually it was supposed to say 1 USD = 100 JPY. This was prod code when I worked at Elavon. Robert was my boss, technically, but really I was seated next to some sorceress Rhonda Capone who occupied the desk McCabe had briefly sat at. Rhonda is evil, and I hate her, and I want her to die, and it seemed like my real job at Elavon was to have to sit next Rhonda and deal with her bullshit all day, while she "managed my project"

How does "you need a new approach to solving a new problem" equate to "Mars won't work?"
Harnessing electricity on an industrial scale wasn't possible for Cro-Magnon Man either, that isn't the same thing as saying harnessing electricity on an industrial scale is unconditionally impossible.
I'm more surprised anyone thought settling colonies on Mars *wouldn't* require radically new ideas / solutions.

Because wasting resources pursing a shit idea is a bad idea, especially when there the dozens/hundreds of plans that are actually viable, not 'ay lameo it would be cool if...'.
Basically, you're a nigger normie faggot advocating we try to make soft scifi real, while ignoring the dozens/hundreds of plans out that that seek to make hard sci-fi real.

Cro-magnon man died out long before electricity was even discovered. That's pretty much the case here with terraforming Mars. The problem has now been found to be so difficult that it's massively beyond the technology we have.

What if they are already making money with small fusion reactors, propping up the economy with the free energy money, and really don't want people to know that they are hiding the free-ish energy technology of compact fusion reactors?

What if all that money rides on never recognizing me for my contributions?

Cro-Magnons were anatomically modern humans and our ancestors.
They didn't die out, they survived and reproduced.
