I think teraforming will eventually be one of those things "people in the past thought people in the future will do but ...black swan... things developed other more logical way" ... like personal planes / flying cars in past envisioning today.

Seriously though, I did not realize how complicated dealing with all that CO2 is. I assumed that we can just shade Venus over for a few decades, let CO2 freeze and have a free reign of the surface. Then again, giant oceans of carbon dioxide have their appeal.

[@stardolphin2]

Now if we could just, you know, open a connected wormhole or two(thousand) between Venus and Mars. Too much atmospheric pressure and greenhouse effect at one, not enough at the other. The pressure differential alone will drive it. Close them off when you've pumped Mars up to whatever you think is best (but don't let them average out).

[@jezzbanger]

In the 22nd century the colonisation of Venus will be subsidised by its role as soda pop supplier to the rest of the solar system!

[@MattOGormanSmith]

stardolphin2, assuming your wormhole obeys conservation of energy, you'd have to account for the potential energy added when you lift the gas out the Sun's gravity well, as well as lifting it out of Venus' too. So, in conclusion, you'll probably need a pump on your wormhole.

[@KuraIthys]

Hmmh. Interesting observation about wormholes and conservation of energy. Never really thought about it. Of course, the energy you're conserving is gravitational potential energy... And a wormhole, insofar as it can be explained with any kind of real physics, is... A spatial distortion connecting two points. In other words, a wormhole is, by it's nature, the same as a very intense gravity well. Quite how this works given it's this kind of distortion at BOTH ends, is unclear... Plus you'd have to solve that whole 'wormhole collapses if matter tries to pass through it' thing. XD What's amusing to me is if you theoretically had a 100% efficient 'antigravity' device; One that effectively cancels out gravitational/mass energy in relation to how much energy it contains. This would mean to move out of a gravity well requires energy, but you gain just as much energy moving into a gravity well. Thus, you can use such a device to move around solely by manipulating how much energy it contains (though it would still relate to the mass of the object it is attached to.) - to be able to move such a device further into a gravity well requires removing energy from it somehow (which, if you exceed the limits of your energy storage capabilities, means your capacity to move towards a massive object is restricted by your ability to radiate energy away from yourself) And moving away from it again requires adding energy. Certainly an interesting fictional propulsion device - I'd imagine it'd be tricky navigating in proximity to multiple bodies, and you'd have to be wary of gravitational dead zones, such as lagrange points... XD

[@AtilaElari]

Thinking about the issue of CO2 I came up with a picture, where the carbon is separated and used to produce carbon nanotubes and graphine for construction material for habitats of Venusian Swarm and planet-side cities, making Venus a World of Carbon, or, more romantically, a Diamond World.

In between each chapter would describe a future epoch delineated by developments like fusion, uploading, immortality, Dysoning, etc. Isaac should be able to sell a book like that on spec, get an advance and spend a year writing!

[@musafawundu6718]

Isaac tears away at the so often peddled narrative of irreversible doom and gloom that prevails in discourse of the future. Even if the worse of climate change occurs, it is reversible. We have the technological wherewithal to do so, especially in terms of a combination of thorium based nuclear power and renewables. Once we apply them and eliminated fossil fuel emissions from the atmosphere, both direct emissions from power stations, factories (using sequestering technology), and IC engine vehicles, but even indirect emissions from electric vehicles powered by grids using fossil fuels, then emissions will drop dramatically to extents that will not cause global warming, and probably indeed there could be global cooling.

[@AtilaElari]

Warframe, while a complete space-fantasy, gets quite a few things surprisingly better than many other space operas - like the fact that pretty much every major body in the Origin system is made livable and has a population of people. Not too big of a population, but that's a result of the post-apocalyptic situation rather than technology level.

[@Sombre_gd]

It's also unique that there are no alien lifeforms. Every faction is either bioengineered humans or man-made organisms.

[@TheLongasen]

[@CrimsonBlasphemy]

Warframe has a lot of really bad and ill fitting Space Magic going on. And often doesn't follow its own plot threads or in-setting rules. "Rule of Cool" is first and foremost. The fact that Venus is "cold" is mainly a goofed art direction as a result of the initial Corpus Outpost tileset which needed to apply to all Corpus planet missions. Venus, Europa, Pluto. Digital Extremes tends to take points the community rags on and doubles down. So we got techno magical "cooling towers" to explain Venus. As another example, Phobos used to have the Grineer Outpost (a desert ruin) themed tileset. Until they switched up the factions and put the Grineer on Mars and Corpus on Phobos. Yes, Phobos, the dinky asteroid of Mars, was a Desert "world" for a while.... Instead of the tileset going to Earth as it had been originally planned. Earth got a super jungle. Venus an ice world. Frankly, DE could use some quality time watching SFIA. At this point, 6 years in, I treat Warframe like Space Wuxia being told by a different further future civilization. The all the facts are wrong and contradictory, often have no grounding in "history", and most of it is just made up. Which is why we kill Captain Vor four times, not counting grinding for loot. Why there are 1, 4, millions of Tenno. Why the Grineer and Corpus can sustain losses in the tens of trillions, in a post-collapse stellar civilization, and it not even be notable. And DE is already trying to slip in alternative dimension wibbly wobbly time-y wimey stuff, as the excuse to hold all of this contradiction together.

[@alanfriesen9837]

As a Venus-firster I love the episode. You're always great at getting the details that often elude me. I've just got a couple of thoughts. I think if we're going to alter the planet's rotation and/or position we should do that first so we're not destroying what we've already built. And while I know it would be more work initially I think in the end we would be glad we made the extra effort to do it right the first time. If I did my math right (no guarantees there) the mass of Venus' atmosphere is about a third of the mass of Earth's combined hydrosphere and atmosphere. Once Venus cools and the oxygen locked up in the sulfur-dioxide is redistributed into water we would probably want all of that atmosphere so that Venus could have comparable oceans. The one thing Venus really needs is the hydrogen you mentioned and a way to keep it from being blown off. If we didn't change the planet's rotation then eventually we wouldn't just have to block the sun on the day side, we'd also have to illuminate the night side, assuming we wanted anything approaching a normal growth cycle. I know you've talked about using mirrors for that kind of thing. An array of grow lights and space heaters might work as well. My vision is of Venus having its rotation augmented for a natural diurnal cycle and having a hydrogen-buoyant network of watering stations criss-crossing the atmosphere at the livable altitude supporting a lattice-work of hanging gardens slowly converting the carbon-dioxide into vegetation and oxygen. We'd probably want to use industrial fixers as well though. Anyway, thank again for the show.

[@tlrlml]

...if we're going to alter the planet's rotation and/or position... Would you like unicorns and fairy dust to go with that disastrous change to Earths orbit, or will extinction be enough?

[@MrJojoy1]

I agree, partly because of my simple-minded solution to the problem. In short, why don’t we just chuck a couple asteroids at it? Calculate the proper trajectories and velocities, and it’d be like using your finger to spin the edge of a basketball. If the impact angle is low enough, there shouldn’t be too much damage to the planet itself. That said, I’d rather not have any infrastructure on the surface of Venus when those asteroid impacts take place...

[@anchorpoint3631]

Or more easier, NASA could build bombs as strong as nuclear ones, but instead these would be designed for cloud seeding, etc in an attempt to alter the weather of Venus and even create an atmosphere . Not to mention an artificial magnetic field. This could be an early stage for terraforming. Afterwards, start sending algae. Could be better than using the other extremely complicated and so much time (yrs) consuming methods that have been discussed a lot such as building massive reflectors, etc. I mean hey, it's better to build said bombs instead of building all these damn nuclear warheads to keep unnecessarily fighting with other countries 🤦‍♂

I would love to see Issac do an episode questioning the origins of UFO's with the premise being that "atleast some ufo sightings are real" i know we've touched on this before in (hidden aliens) but alot of people love jumping straight to aliens rather than fully considering the facts, for example, we've never seen a ufo in space or entering earths atmosphere which we're pretty unlikely to miss, so assume they're of earthy origin but fully explore not only the silurian hypothesis where a dinosaurian civalisation secretly survives but the possibility of unknown humans or our close relatives like homo habillis, a Neanderthal cousin that evolved a very lean bone structure due to living in caves and needing to squeeze through tight passages, surviving and evolving their technology more or less at the same rate as us, could we be sharing earth with another civalisation? And what would such a civalisation be like, what would the near infinite thermal electricity available under the earth enable them to do? How would they're evolution diverge if they separated from us a million years ago? I feel like issac is basically the only youtuber equipped to attempt a video like that as the more you think about it the more questions arise.

One potential local source of hydrogen to Venus is the sulphuric acid (H2SO4) rain. I’m curious if one could sequester the sulfur in the form of sulfur dioxide (SO2) leaving behind H2O and O2. 2 H2SO4 -> 2 H2O + O2 + 2 SO2

[@amandadausman7845]

We need to understand more about Venus's geology before we can (responsibly) colonize the surface. Venus doesn't have plate tectonics for one, and "catastrophic resurfacing" is one of the leading explanations for why the surface looks the way it does. Catastrophic resurfacing is the craziest thing I've ever learned about planetary science.

[@bartjanc]

"getting to" does not equal "terraforming" though. Getting to Venus probably isn't harder than getting to Mars (as long as you stay in orbit and don't go down)

[@classarank7youtubeherokeyb63]

@Roger Dottin No, there is no ultimate goal. We keep expanding until we can't anymore, no matter where that boundary lies.

[@douglasphillips5870]

Let Musk build the infrastructure for teraforming Mars, and use it to jump start the teraforming of Venus.

[@orlandovazquez8694]

Scientists foresee Humanity's ruin through the overuse of fossil fuels and possibly other calamities and extinction events, that's where technology, inter-planetary exploration and eventually colonization all come together. Interstellar travel is such a long way from now extinction is inevitable if you really think about it. Only if mankind survives another 1000 years or so without global wars or killer asteroids and just advancements can we make it, which is a long shot. Close to light speed travel would be the only way to go interstellar. Or the Alcubierre warp drive. I don't see humans making it that far. Space is too problematic when you factor in UV radiation and such things. Humans themselves would have to evolve physically to survive long-term space travel alone. Problems with bone density from zero-gravity or cosmic rays kill. Too many factors.

Hard, the land we call our home

[@hdufort]

Currently, Venus has an external magnetic field caused by interaction between the magnetosphere and solar wind. It is not as efficient as Earth's though, 10% of protection only. Since Venus is 2x as close to the Sun, it receives 4x the radiation, so someone standing on Venus would get 40x the radiation they would get at the surface of Earth. Not as bad as Mars or outer space, but still an issue. And if we cool down the atmosphere by stripping it or precipitating it, this protection might also decrease.

[@craigmooring2091]

I wonder if we could combine the terraforming of Venus with the terraforming of Mars. Start with Venus then find a way to 'truck' some that excess, precipitated atmosphere (in the form of sequestered carbon and O₂) to Mars using the same 'shade and reflector' technology modified for Mars' conditions to keep the Sun from stripping atmosphere as we build it up while warming the surface. At any rate, a permanent, low maintenance terraforming of Venus does seem more achievable than it does for Mars.

[@bookcadenb4584]

We need to stop worrying about terraforming another Celestial body, that is far beyond our capabilities at this time, and just realize that we are going to have no choice but live in Habitats or under Domes for many Generations after first Colonizing said Celestial body like Mars, the Moon, etc. We have the technology today to build Habitat style Colonies and we need to concern our effort at improving that technology. Terraforming can and should come later.

[@meanelkiddo]

[@HouseJawn]

Great episode Issac. Its amazing Venus doesnt get discussed more often. It seems like our culture is dead set on Mars come hell or high water. Colonize all of the planets, but Venus seems better, easier, less financial commitment and investment.

[@tlrlml]

Perhaps that is because we stand a chance of not being crushed and fried if we land on Mars today, even for a short visit... where as we could not say the same for Venus. As far as financial commitment to terraform... you'll find Venus has the greater expense (it spins wrong, it is harder to cool then to heat, it's upside down, we couldn't hope to put anything on the ground, any liquid water has long since evaporated, etc, etc, etc)

[@kevincrady2831]

Alternatively, terraforming could happen as a side-effect of colonization: start with the floating cities, using solar power and atmospheric heat to extract carbon from the atmosphere and turn it into materials (diamond lattice, nanotubes, graphene, graphite...). Gradually build up to Active Support tech; Orbital Rings, floating colonies knit together to become "islands," then "continents," and so on, eventually turning Venus into a Shellworld. Once the first Shell is complete (made from atmospheric carbon), the surface is shaded. Continue extracting heat, carbon and oxygen until pressure and temperature are at desirable levels. Add artificial lighting to the bottom of the lowest Shell. The biggest remaining task would be to import H2 from the Sun or elsewhere to start adding water to the surface. This could potentially be a gradual process as well: people start by building domed-over lake resorts, nature preserves, mining operations, and the like and importing hydrogen for fusion power. As these proliferate, water vapor leaks into the atmosphere or is put there deliberately along with genetically engineered "terraforming biology," until the domes are no longer necessary. Instead of doing stuff to Venus and waiting for it to become habitable, inhabiting it would make it more habitable over time (basically, a technology-boosted version of how life spreads to previously uninhabited areas like new islands).

[@jonathanburmeister1946]

Probably start off as a mega mining project. Building a shade to cool the planet so the weather of resources can be developed.

[@SpazzyMcGee1337]

I would like to see the calculation for the two century estimate of cooling Venus with a solar shade. It sounds like a conservative estimate for any other planet, but Venus doesn't receive that much energy from the sun anyway due to its high albedo. A solar shade would therefore be less effective there than other places. It's worth crunching the numbers because for all we know it may actually take thousands of years to cool Venus using a shade.
