ACKCHYUALLY it would be much more energy efficient to build a giant solar panel that would eclipse Venus, and have orbiting mirrors to reflect an Earth-like amount of sunlight onto Venus.
Yeah, I can still see it being done in some cases but I suspect our own solar system will be done mostly as test cases and in the future around other stars it would only be where it was very low hanging fruit, 23-26 hour day, +/-10% Earth year and gravity, about the right temp already
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. But someone will do it if nothing then just for show...i mean in future teraforming Vrnus will be stunt on par with dubai-s artificial islands or flying cars quad-copter police ( saw a video few months ago..looks cool but uterly useless for practical police work...i mean just get a drone same thing :P )
I say both. I like to envision a future where the Solar system has these two shining jewels, one primordial and one by design, and both with formations of O'Neil cylinders, which form slowly spreading clouds about their Lagrange points, as they do those of Mars, the Sun, the Jovian moons and throughout the belts. What a thing that would be to see.

"How to make very hot planet comfortable and livable? Just shoot a beam of solar matter at it for a few years, then let it cool, nothing complicated". 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.
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).
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.
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
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.
Rainy afternoon outside & about to sit down with lunch when I get the notification for more terraforming, perfect. I'm glad this channel exists, and that it's not raining carbon dioxide outside. Thanks for making youtube a better place.
If we could ever make wormholes it would be awesome. Imagine one on Venus and one on mars. Just vent the atmosphere from Venus until Venus gets cold enough and mars heats up. You could do it on a lazy Sunday afternoon. 😉
@@joshglover2370 I dunno if we're hauling around wormholes maybe a filter to just let in the carbon dioxide and nitrogen only wouldn't be too high tech.
Every time I think about such things, I wonder how long my sanity would hold out with 'eternal' life. I could be completely wrong since I have no reference even of other people living that long, but I always get the feeling 10,000 years is about the point past I which I just wouldn't cope with it anymore.

@Hue Man Warframe is a game about uh well basically its sci-fi murder parkour with lots of loot. Their last expansion, Fortuna, takes place on a badly terraformed Venus where ancient tech went a bit too far and made it permanently winter. SFIA = The channel, DE = Digital Extremes, the makers of Warframe.
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.
Yet another fantastic episode of my favorite series on RUclips! Arthursday deserves full sponsorship from PBS or better. Also, who wouldn’t want to read a book by Isaac? I can imagine the chapters organized by years in the future; the first chapter is what is possible or should be in 20 years, the last chapter would be about the end of time- black hole civilizations and iron stars and maybe an epilogue on infinity and Boltzmann brains. 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!
I would like to join or participate in the cooperative citizen organization that executes these ideas. Get a half a billion people to share the dream (and open wallets) and we get orbital rings.
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.
...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?
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...
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 🤦♂
why lob asteroids at Venus, when we can orbit gravity tractors to do the same thing, and the gravity tractors can be reused to move large asteroids@@MrJojoy1
I also wanted to mention that terraforming Venus into a habitable planet happened in S-F game Warframe - tough they botched because war in the solar system and things and now it is really winter chilly
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.
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.
@@AtilaElari it has its problems for sure (how are the grineer good at genetics but still have clones that are getting worse with each new batch? store redundant copies of the template digitally, problem solved) but every so often they do something interesting that's also plausible

@@b.lonewolf417 Yep. Correct. I understand the sponsorships, being in broadcasting myself. I don't mind them at all, especially on Isaac's channel. I've seen some channels that have as much sponsorship content as their actual product. Isaac is definitely one of a kind, in research and presentation. A totally enjoyable experience.
Nothing makes me happier than a new video on SFIA. Man all my friends talk about Mars and I agree with you, when one gets down to brass tacks Venus really is a better candidate for terraforming.
We'd love to sell you a few gigatonnes of nitrogen, but our extraction infrastructure is already running at full capacity and we're waiting on new equipment from Luna to expand it, so there's a waiting list. We could pencil in your order for two Earth years from now, though.
Me too. I'm skeptical about slamming Mercury into Venus to push it to Earth. I think she can best be terraformed where she is, allowing many different initiatives...
with every mention of blowing off venus' atmosphere, i lamented the waste of precious nitrogen. imagine how we'd feel a few centuries later collecting it from titan and the sun
Honestly, I don't find the camera functionality of a smartphone to be very useful. Most of the time if I'm out and about and see something I'd like to photograph, I find myself wishing I had a camera, completely forgetting my phone has one built in (and won't sit flat because Samsung was stupid about how to handle its presence). Even when I do remember it has one, half the time I never end up taking a picture because I can't compose one that looks any good. And that's just for still images. I can't see video being any better, and given the extra dimension to the medium, I expect it would be far worse.

I was literally trying to study this topic for a hard sci fi novel I'm prepping to write. Have you secretly discovered Psychohistory or something *Isaac* Arthur?
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.
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)
How on earth Issac manages to cover these topics so comprehensively is beyond me, he not only presents and details a premise but then explores that premise fully within the confines of the topic, very rarely leaving you with a question that goes unanswered. Another half an hour well spent. 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. Unfortunately i know Isaac kind of dislikes the whole concept of UFO'S being anything other than schizophrenia and classified technology though so ill probably never see these topics fully explored here 😢😭
I’ve been cleaning my house all day yesterday and today listening to you, very amazing and interesting heading out to the stars, Really enjoy your channel.
The first part of this episode reminds me a lot of the venus we see in the game "Warframe". Where a self-sufficient cooling system has been running since the fall of the old empire and the entire planet is basically a freezing hellhole. it also has an artificial sun (at least in the "Orb Vallis" where an underground colony has been warming the valley)
Cold: the air and water flowin' Hard: the land we call our home Push, to keep the dark from comin' Feel the weight of what we owe *WE ALL LIFT TOGETHER.*
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.
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).
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
The accent of the narrator, makes this video of Venus, worth watching. And astronomers today, theorize that Venus, was indeed, once inhabitable. Then it got too damn hot.
I really want Isaac to talk hypothetically about the CHEAPEST way to kill all humans quickly. We might assume that's what competition-fearing aliens will go for. Cheapskate apocalypse is on its way.
Hey Isaac, you should start using Kerbal Space program to do some spaceship visuals. It would look a lot more goofy, but also awesome. You'd love that game.
Colonizing Venus was the introductory episode that got me hooked to your channel, so I am very happy you are revisiting the topic. I love the idea of humanity one day enjoying a cozy Venusian evening, dozing off on their rocking chair as its moon rises from the horizon.
F-ing A!!!! It's Arthursday!!!! Thank you for taking me awesome places once a week going on a year for me now. I hope we live to see at least some of these scenarios to play out. I am not betting on it though.
Excellent ideas! I'd pretty well written off Venus since the mid-Sixties. It was with real regret, too. I still remember that depiction in Space Age magazine of a spaceman standing on Venus, his rocketship in the background, watching a brontosaurus calmly chewing his cud! It's silly, of course, but the idea of a terraformed AND bioformed (Jurassic-like!) Venus strikes a warm chord in my heart. Boyhood dreams...!
"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)
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.
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.
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.
Had a victory today and I'm a bit drunk. To be honest I will enjoy this juicy saved episode far frocking more than the restaurant bar. Not many warrior physicists tuck me in hammered. Semper Fi, bro...Thank you out
how I wish people understood how leaving critical comments on videos they dislike also work this way. "If you don't have anything nice to say, don't say anything at all!" That truism goes quadruple for RUclips.
@@squirlmy I understand your point but also realise there have been comments I have read from viewers that have clearly disliked a certain video which have given me an insight into a different way of thinking. Sometimes negative comments need to be aired anyway (regardless of the algorithm). That said I have nothing but positive vibes for Issac Arthur. (edited because I spelt Issac's name wrong which is embarrassing considering how many years I have been watching his videos).
Hows about: Use the sun shade as a solar farm, use the energy to split the CO2, outgas the carbon at an angle that will slightly speed up the planets rotation and put the carbon into Venus orbit, creating a ring system that can be coalesced into a proto moon. I have no credentials whatsover, but I like to talk.
We did actually kick something parallel around, but in the end as much carbon as it is, its not really so much that we want to go out of our way to retain it

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).
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!
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.
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
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.
Rainy afternoon outside & about to sit down with lunch when I get the notification for more terraforming, perfect. I'm glad this channel exists, and that it's not raining carbon dioxide outside. Thanks for making youtube a better place.
If we could ever make wormholes it would be awesome. Imagine one on Venus and one on mars. Just vent the atmosphere from Venus until Venus gets cold enough and mars heats up. You could do it on a lazy Sunday afternoon. 😉
Then you have 2 shitholes with no breatheable air and sulpheric acid all over everything! 😳
Is this what's called global worming? :D
@@joshglover2370 as opposed to now?
@@rickhernandez2114 Well if we ever want to grow food in Mars soil, we can't very well have sulpheric acid in it!
@@joshglover2370 I dunno if we're hauling around wormholes maybe a filter to just let in the carbon dioxide and nitrogen only wouldn't be too high tech.
We live in decades, to live in this universe me need to live in millenniums or even eons. Then everything becomes natural and to scale.
Every time I think about such things, I wonder how long my sanity would hold out with 'eternal' life.
I could be completely wrong since I have no reference even of other people living that long, but I always get the feeling 10,000 years is about the point past I which I just wouldn't cope with it anymore. XD
KuraIthys, if you left out artificial enhancements beyond life extension then you would only really remember a century or two at most I imagine, and then you could do everything again a few times while you waited for the next big thing to finish. Not a bad life all things considered
@@KuraIthys we don't even have 10,000 years of recorded human history to judge by. I'm feeling pretty damn tired and worn out near the half-century mark! Without actual experiences, I'd be nervous about anything over the 250 year mark, long before even 1000 years.
@@KuraIthys You might want to look at the Long Now gang. They're people like Brian Eno, Stewart Brand, etc. who want to encourage long-term (centuries, minimum) planning and thinking. Their 10,000 Year Clock with jade cogs and a regulating cam that takes into account Pole Star precession(!) is a fantastic idea.
Elon Musk will give us all robot bodies in 2029! Then we can live wherever we want!!
*"... and shove the whole thing into a counter-Eath orbit on the opposite side of the Sun, but I'd consider that overkill."*
No such thing, Isaac. *FIRE UP THE STELLASER! MARS SHALL FOLLOW!*

Why not just combine mars and mercury into one big planet
I love this community and how it intersects with the Warframe community, SFIA and DE are both amazing
@Hue Man Warframe is a game about uh well basically its sci-fi murder parkour with lots of loot. Their last expansion, Fortuna, takes place on a badly terraformed Venus where ancient tech went a bit too far and made it permanently winter. SFIA = The channel, DE = Digital Extremes, the makers of Warframe.
Isaac Arthur, your confidence our our ability to control the climate gives me great hope!
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.
C'mon, man! Not even ready for winter on this side of my own planet.
37 Minutes more sleep? Yeah my job would be like, 37 minutes more work!
Yet another fantastic episode of my favorite series on RUclips! Arthursday deserves full sponsorship from PBS or better. Also, who wouldn’t want to read a book by Isaac? I can imagine the chapters organized by years in the future; the first chapter is what is possible or should be in 20 years, the last chapter would be about the end of time- black hole civilizations and iron stars and maybe an epilogue on infinity and Boltzmann brains. 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!
I would like to join or participate in the cooperative citizen organization that executes these ideas. Get a half a billion people to share the dream (and open wallets) and we get orbital rings.
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.
...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?
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...
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 🤦♂
why lob asteroids at Venus, when we can orbit gravity tractors to do the same thing, and the gravity tractors can be reused to move large asteroids@@MrJojoy1
I also wanted to mention that terraforming Venus into a habitable planet happened in S-F game Warframe - tough they botched because war in the solar system and things and now it is really winter chilly
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.
It's also unique that there are no alien lifeforms. Every faction is either bioengineered humans or man-made organisms.
Yeah, I like the Warframe lore because it's still grounded on our solar system.
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.
@@AtilaElari it has its problems for sure (how are the grineer good at genetics but still have clones that are getting worse with each new batch? store redundant copies of the template digitally, problem solved) but every so often they do something interesting that's also plausible
Oh, hello there. I'm just here to wish you a Happy ArThursday!

That's about the smoothest transition into the sponsor content I've ever heard, (and I write and voice commercials for radio and internet). I'm also a meteorologist, and I wish I had a 10th of the brain that Isaac has.
Yeah, Isaac Arthur tends to handle sponsor content very well. I also like the fact that the product is often something that would DIRECTLY appeal to the majority of users! I like to think I'm a reasonable person, so I respect content creators' need to work with sponsors; when they handle it this well, it is so so nice!
@@b.lonewolf417 Yep. Correct. I understand the sponsorships, being in broadcasting myself. I don't mind them at all, especially on Isaac's channel. I've seen some channels that have as much sponsorship content as their actual product. Isaac is definitely one of a kind, in research and presentation. A totally enjoyable experience.
Before watching: “How?” 🤔
After watching: “Wow!” 🤩👍
Nothing makes me happier than a new video on SFIA. Man all my friends talk about Mars and I agree with you, when one gets down to brass tacks Venus really is a better candidate for terraforming.
Hello, I'm a representative from Rotating Real Estate Heavy Industries, and we'd be happy to take some of that excess nitrogen off your hands.
We'd love to sell you a few gigatonnes of nitrogen, but our extraction infrastructure is already running at full capacity and we're waiting on new equipment from Luna to expand it, so there's a waiting list. We could pencil in your order for two Earth years from now, though.
Want to winter at Venus one day. Preferably 50km up on a beach in a cloud city.
Me too.
I'm skeptical about slamming Mercury into Venus to push it to Earth. I think she can best be terraformed where she is, allowing many different initiatives...
Isaac, you might not remember this, but iirc we talked once in the comments about terraforming Venus -- this is one of my favorite space-topics :)

Honestly, I don't find the camera functionality of a smartphone to be very useful. Most of the time if I'm out and about and see something I'd like to photograph, I find myself wishing I had a camera, completely forgetting my phone has one built in (and won't sit flat because Samsung was stupid about how to handle its presence). Even when I do remember it has one, half the time I never end up taking a picture because I can't compose one that looks any good. And that's just for still images. I can't see video being any better, and given the extra dimension to the medium, I expect it would be far worse.

@Let it be. Zon
I was literally trying to study this topic for a hard sci fi novel I'm prepping to write. Have you secretly discovered Psychohistory or something *Isaac* Arthur?
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.
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)
How on earth Issac manages to cover these topics so comprehensively is beyond me, he not only presents and details a premise but then explores that premise fully within the confines of the topic, very rarely leaving you with a question that goes unanswered.
Another half an hour well spent.
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.
Unfortunately i know Isaac kind of dislikes the whole concept of UFO'S being anything other than schizophrenia and classified technology though so ill probably never see these topics fully explored here 😢😭

Isaac Arthur: The only man who can invent the verb 'Deathstarring', and also use it in a positive context regarding teraforming Venus.
Let's move to venus boys
The first part of this episode reminds me a lot of the venus we see in the game "Warframe". Where a self-sufficient cooling system has been running since the fall of the old empire and the entire planet is basically a freezing hellhole. it also has an artificial sun (at least in the "Orb Vallis" where an underground colony has been warming the valley)
A second teraforming venus video? You've got me.

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.
Thank you for giving us this wild content. I love it.
Keeping the Earth in the Habitable band is also a good idea. Then just need too keep its molten core liquid so the magnetic field is active.
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).
Probably start off as a mega mining project.
Building a shade to cool the planet so the weather of resources can be developed.
Thank you, Isaac!
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
Alright everyone. Time to disassemble Mercury for materials.
Thats so mean :D
That's so necessary. "Kardashev 2" achievement unlocked. Let's grind it out!
The accent of the narrator, makes this video of Venus, worth watching. And astronomers today, theorize that Venus, was indeed, once inhabitable. Then it got too damn hot.
You got me on board, Occupy Venus!
"Hydrocannon" sounds more like a water stream than a hydrogen one. Maybe Heliocannon?
But then you’ve got to remember why we needed the hydrogen in the first place...

Colonizing Venus was the introductory episode that got me hooked to your channel, so I am very happy you are revisiting the topic. I love the idea of humanity one day enjoying a cozy Venusian evening, dozing off on their rocking chair as its moon rises from the horizon.

Combined American accent + IA speech problem: mirror --> meeyour.
Finally, I've been waiting for a long time for this.
Excellent ideas! I'd pretty well written off Venus since the mid-Sixties. It was with real regret, too. I still remember that depiction in Space Age magazine of a spaceman standing on Venus, his rocketship in the background, watching a brontosaurus calmly chewing his cud! It's silly, of course, but the idea of a terraformed AND bioformed (Jurassic-like!) Venus strikes a warm chord in my heart. Boyhood dreams...!
Good luck trying to convince Elon Musk on this 😂
The guy built his whole life purpose based on getting to Mars
@Roger Dottin Interplanetary, but that's the idea - Starship is supposed to become our 1st in-system cruiser design.
"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)
@Roger Dottin No, there is no ultimate goal. We keep expanding until we can't anymore, no matter where that boundary lies.
Let Musk build the infrastructure for teraforming Mars, and use it to jump start the teraforming of Venus.
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.
10th and Teno brothers do not let corpus rule Venus with iron fist xD
Cold, the air and water flowing
Hard, the land we call our home
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.
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.

wait isn't this literally Warframe?
Hows about: Use the sun shade as a solar farm, use the energy to split the CO2, outgas the carbon at an angle that will slightly speed up the planets rotation and put the carbon into Venus orbit, creating a ring system that can be coalesced into a proto moon.
I have no credentials whatsover, but I like to talk.
We did actually kick something parallel around, but in the end as much carbon as it is, its not really so much that we want to go out of our way to retain it
