[@pikazilla6405]

I disagree with the notion that terraforming is a waste of time and resources. Humanity needs life, it needs ecosystems, these are crucial for food production and the creation of complex chemicals that aren't found in lifeless planets. Not to mention the crucial role they play in the mental wellbeing and culture of human civilizations. This is something that super structures built from asteroids simply can't replicate and the creation/maintanence of ecosystems should be a high priority concern for a future space fairing humanity. Also want to add that concerns of Venus terraforming beings "profitable" are fairly laughable, it's insane to imagine a future where planet terraforming is possible and capitalism still existing, this would be so far in the future that the combination of an immense human population and automation taking over would render a job market completely unviable and our systems of government and economies would have to be overhauled to adapt.

[@theshumsshowforfun2.051]

Hey! There is a lot of good points made in this video. But I will make an argument that while Venus may be the more easier one to terraform than Mars. Mars does have the advantage of being near the outer solar system. So it could act as some sort of bridge incase we’re interested in doing operations such as mining the asteroid or Kuiper Belt or beyond. Also you forgot to mention gravity on a terraformed Venus will be the biggest advantage compared to a terraformed mars as it’s somewhat close to that of the Earth and Zero G effects on humans is one of the most concerning things that are never talked about if it comes to sending humans in places outside of earth. It would be interesting video idea if we get something like centrifugal forces and how we can adapt our bodies better for space environments

[@tsovloj6510]

You gotta remember that with gravity slingshots around the sun, and with the fact that the outer planet destination is gonna be on the far side of the system from Mars about half the time, Venus is probably "closer" to the outer system in an orbital mechanics, delta vee rocket equations sense.

A lot of the issue is trying to terraform fast, though. If you're willing to use local resources and take millennia to do it, the situation improves somewhat. The only thing you'd really need to import is hydrogen in the Venus case, and the Bosch reaction creates energy as well as water, so it'd probably pay for itself. From there you just wait until the whole atmosphere is processed.

The profit motive is a terribly defective and inefficient reason/way to go about terraforming(or for really anything else for that matter) in any responsible manner. I mean just at look how we treat our own planet for profit already. Terraforming for profit gain would be far too expensive for anyone to seriously really consider and if we did, the process would likely be undermined by things like cut-cornering, wastefulness, and whatever other bad business practices you can think of which could have great consequences for whatever planet we go with.

When you speak of profit I take you to be referring to utility as I don't think any profit-seeking institution would ever engage in terraforming. Also, it is hasty to assume the economic system of the future. The "profits" from any such enterprise will be so far in the future that few humans would choose to terraform for "personal" gain. As for the proposed solar panels, why waste money trying to keep them in a specific place for hundreds of years when one could build them closer to the sun and not worry about such things? There is still much utility in terraforming (even if I agree with you on the point that there are better options out there), but any effort to gain it will have to be made by non-profit institutions like governments. Ultimately, governments may be even less likely to terraform as they must provide goods to their voting public within their lifetimes. But that's assuming democracy, an autocratic technocracy could muster the will to do it given it lasts hundreds of years. In the end, I agree with you.

In just a few years, the intelligent species native to Objecia quickly terraformed objects like those I mentioned. But honestly, I don't think terraforming irl will be that quick. It would take hundreds, thousands, or even millions of years to terraform an entire planet. It's just the native species of Objecia has technology fast enough to quickly terraform entire planets, and they live in a galaxy where most star systems have at least one habitable planet. So, terraforming could work well in a fictional setting. But, let's get back to the real universe. So, is terraforming possible?

Of course, perhaps future humans have adapted physically to a low-g environment, but the mental impact of living off planet for an entire human lifecycle are simply not known. 2. A moon or artificial space habitat is not nearly a good enough starting point from which to rebuild after a human-life-on-planet ending impact. It's more fragile and there's less resources.. not least of which, most likely way less humans than would've lived on the planet that was hit. There's not a lot of strategic depth in such a scenario, not a lot of wiggle room if things go wrong a second time.

[@Kyplanet893]

difference with the moon is if some apocalypse happened on earth, they’re right there and the moon is a perfect place to set up huge industries so will have all they need to build ships and stuff so they are in a perfect position to rebuild after a disaster in a scenario where earth is in post-apocalypse isn’t about surviving long term, it’s about being able to get back to earth (and rebuilding it) as fast as possible and otherwise, low-g actually isn’t that big of a problem on the moon again because of how close it is to earth. The moon doesn’t need permanent populations because of how close it is.

Venus is 3 time hotter than bacteria temperature limit. Mars has not magnetic field to protect primitive life ...

Carl Sagan himself actually suggested this for Venus way back in the day when we thought it had maybe 3 or 4 atmospheres worth of CO2. Once we sent the first probes and it turned out to be more like 90 atmospheres, we had to give up; basically, if you turn that much CO2 into O2, everything's going to be so insanely flammable that eventually it'll catch fire and everything will just turn into CO2 again. Also not enough water for microbes.

Are we not gonna talk about the gravity on venus being much closer to Earth compared to Mars?

[@tonytaskforce3465]

Makes no sense. Space habitats rule.

We need to figure out to expand our sun’s lifecycle so we can build better technology to get to the next solar system assuming it has good planets.

Ok but what will it take to lunaform the earth?

[@FleshWizard69420]

My first idea was inducing a chemical reaction to turn all the CO2 into oxygen, but that comes with 3 major problems 1. Where would I get that much reactant 2. The intense pressure still remains 3. The atmosphere would now be incredibly oxidising I like your idea better

[@tsovloj6510]

This has been suggested, sort of. In the presence of iron, CO2 reacts with hydrogen to form water and carbon and emits energy. You'd import hydrogen from mining it out of the gas giants (Uranus probably, has the least steep gravity well), react it with the atmosphere, and you get water and energy and potential construction material in the form of carbon. This both gets rid of your atmosphere and gets you some shallow oceans. The main problem is you'd need this to be happening at a vast scale for a very, very long time, like millennia. Given the energy produced, though, it's probably cost-effective in the short term sense, so it might be viable. Towards the end, when the CO2 is low enough, you turn most of the last bit of CO2 into O2 the way we do on Earth, with plants.

Guys...why terraform? Let's just nuke the sun

We can't even change our planet into a better place

[@dynamicworlds1]

I mean, we COULD. We're just choosing to do the opposite.

[@Gutigwolfe]

For people who live on the Poles of Earth, several months of sun or darkness would be normal to them. Life could still be sustained, but would need to adapt to the long days and nights. While I don't see Venus being Terraformed, it is a interesting idea what a habitable Venus would look like, I feel it would look very similar to Earth.

[@thenarwhal7866]

Also honestly who get excited about space habitats? Terraforming is a grand project that can bring all of humanity together. A space habitat is just a big spinning space station.

I can't wait when we terraform Antarctica and Sahara desert

[@Mens_Rights]

Are you actually i - n - s - a - n - e? If by "terraform," you mean "make into a comfortable environment for humans," doing so in Antarctica would melt the southern icecap, raising sea level by a few hundred feet, drowning cities and even entire countries, and interfering in the circulation of seawater, because you'd be shutting down convection in the South. The last time anything like that happened, the Permian extinction followed, and a causal connection between the two is likely. If the ocean currents slow, then the deep oceans start running out of oxygen, setting the stage for global disaster when the currents return. Please leave science to the scientists.

[@igorbondarev5226]

@@Mens_Rights It won't happen if you properly "terraform" the shores first. Anyway, is my Sahara paper accepted?

[@dynamicworlds1]

We can only have 1 of those. Either we get runaway climate change that melts the antarctic ice cap and renders the Sahara uninhabitable for human life OR we get climate change under control and leave the Sahara inhabitable but the Antarctic covered in ice.

[@josgibbons6777]

The habitats you'd prefer would initially be made from small bodies with shallow gravity wells, but our population might over centuries expand enough to need to dismantle something larger. If we ever want to use Venus, the largest rocky body excepting Earth, we'd need to start centuries ahead. It would require most of the atmosphere destruction terraforming needs, as otherwise machines couldn't work the surface.

[@eatham.]

Good video my only personal criticism is the focus on "profit and cost" when thinking about it. Like any space-related things, the focus likely wouldn't be for profit it would likely be a publicly funded effort by the state or a global human effort, not a private corporation or something expecting returns idk. While I do completely understand the reasons you have for being against terraforming, there is a deep part of me that just thinks it's cool even if entirely impractical. I'm curious what your thoughts on bioforming is then in the case of being against terraforming, while there would still have to be some terraforming done to an extent some significant parts of it might be avoided by bioforming as well.

I know you say venturing to mars would be more effort than it is worth, but what about its moons Phobos and Deimos?

[@Kyplanet893]

in the very far future they’d be good counterweights for skyhooks but there’d be no point in building those unless we have significant presences across the entire solar system they’ll be useful later but not now

[@TheTrueZenix]

@@Kyplanet893 And so does relying on those moons to ship water to venus i would not say terraforming venus is easier than mars.

[@tgavran1870]

I don't think we actually need mirrors in Venus orbit for a 24 hr day. It takes Venus 243 days to rotate, but that's the _sidereal_ day. The actual *solar* day on Venus is 116 days long with the daytime and nighttime each being 58 days. If we terraformed Venus, the water would evaporate faster during the day and turn into clouds which would raise the albedo of Venus. Some people did the math and they found out that the day temperature would reach only 35°C max (I beileve that's 95°F).

Terraform earth first then you can try to imagine doing it elsewhere

[@srussell7718]

Well there is another way they the standard cool Venus off. We could design a stalaser, using the suns atmosphere and power to generate powerful lasers, these laser could be used primarily to produce solar sail highways to move ships across the solar system. A portion of this energy could be used at specific wavelength to blow off atmosphere from Venus. Given the energy out out by the sun this could be a very repid process yeas it would heat up Venus, but with Venus having a much thinner atmosphere, the heat could not be retained for an extended period of time like it would with a thick atmosphere. Then you can cool Venus off at a much faster pace.
