Hey Issac what are your thoughts on the relative efficiency of terraforming worlds vs building space habitats? I think that terraforming worlds is more popular with the general public. Rotating habitats might be better in regards such as safety in numbers and being highly customizable.

I bet he says rotating habitat is more feasable. Terra forming is a LOONG process...plus I don't think plate tectonics have ever been discovered on any other objects afaik.

Another point Isaac mentioned in previous videos is that you can make habitats in systems that don't have viable planets, meaning every system can be colonized.

a colony ship having a contingent of Amish (or equivalent) people on board. Absolutely! Should be a requirement. I'm a big fan of of remembering how to do it manually in case of technology failure. I know our local hospital does this every couple of years. They force the staff to work a full 24 hours with minimal tech -- not to the point that it endangers patients lives -- its not that extreme. But it does serve to remind the staff and community that can go horribly wrong. We are prepared -- Mostly.

I am still of the opinion that terraforming any planet that is not already 90+% livable is a waste of time and resources when compared to just mining and building habitats like O'Neil or McKendree cylinders in space where you can control every bit of the ecology and atmosphere and gravity strength. Disassembly of a planet to build cylinders lets you make space for more people than that world would ever allow by a large amount and you get to build those incrementally.

What I like the most about sci-fi depicting an interstellar ark escaping dying Earth(like it's claimed in Avatar 2 or in... was it Elysium?) is that you've just created massive autonomous self sufficient closed off biosystem with crazy level of redundancy and you somehow DIDN'T apply the same tech to solving Earth's problems? How?! Irl just designing and building an ark would already slowly start fixing most of the problems or avoid them entirely as you would apply all that tech to cities and industries on Earth too.

I posted on another thread that Mars and other wolds with far below Earth gravity cannot be inhabited long term or permanently by humans because the human body needs close to Earth gravity to be healthy. Avatar would probably be fine since the human body could probably adapt to 80 percent Earth gravity but Mars has less than half of that. Not enough gravity. Too little gravity is very bad for human health. Zero G would kill most people or cause permanent health problems in a year and a a half (maybe even less) and Mars gravity is better for health than no gravity at all but several years of this "gravity deprivation" would make a Mars colonist way less healthy than if they were on Earth. Planets with low gravity like Mars cannot be Terraformed for this reason even if EVERY OTHER aspect of supporting life was done successfully.

One such example presently underway is the Great Green Wall project in the sub Sahara to push back the desert. It's a toy version of the terraforming scenarios here but think of it as a dry run.

Here's another Fermi Paradox question the subject of terraforming brought to mind. One might be reluctant to colonise any planet that has any possibility of life, for either moral or practicable reasons. Barren rocks may in turn be poor candidates. But a planet with intelligent life is ideal for visiting as one can ask the locals. Even if you didn't plan a hostile takeover your more advanced technology will result in your replacing the original inhabitants. So why haven't we been replaced?

[@richardgreen7225]

I think that before we go terror-forming other planets, we should decide how to adopt/adapt our own. There will be numerous debates: - Should we deforest the land to grow crops? Or, adopt a lifestyle more compatible to living in a forest? - Should we learn how to utilize existing grass-eaters? Or, substitute grass eaters from a distant place? - Do we prefer the simplicity of industrial mono-culture? Or, enjoy a diversity of crops on the same land? - Should we drain natural lakes to save farmers who have mismanaged their fossil water aquifers? - Should we place domes over desert lands to retain moisture and make such places habitable? - Should we allow natural predators in our neighborhoods? (fox, wolf, bear, hawk, cat)

It'd occur naturally as a function of the volume of air and moisture present. You get condensation drizzle in contemporary enclosed sports stadiums, and an O'Neill is orders of magnitude larger. Wind would be a function of the shell spinning while the internal air remains static.

[@scottbillups4576]

@@harbl99 I am aware of the weather inside sports stadiums. My question is linking to - is the the drum is spinning, would friction cause the air to spin too, therefore stratify (gentle pressure differences from core to surface)? What would cause the wind? I think all the air would rotate, but there wouldn't be any temperature differences to drive winds. Similarly, what would cause clouds? Yes, there would be humidity, but would there be strong-enough pressure differences to cause the self-condensation needed for clouds?

I feel like we are going down the route of pre-manufacturing elements on a terrestrial scale. If you have a space habitat that can accelerate for a new planet they can just plop that down on the planet effectivelly INSTANTENOUSLY terraform that patch of the planet. If we take into account the wast time requirements of traveling to a new planet, we maybe looking at so many of such examples on the same planet it effectivelly cover the entire planets surface, connecting the habbitats with some service roads (probably underground for shielding) and only a fraction of the planet would remain its original self, uncovered. Now im not talking about actual full on habitats to cover the planet, but along the journey you manufacture un-countable square kilometers of grass land or crop fields that you use anyways to start beefing up youre population and you just land it, piece by piece or the whole thing depending on your options. So you either just use the planet as a gravity well at that point or make great haste terraforming the un-covered areas still left from the planet after planetfall.

You might want to check more recent papers - there was a big one a decade ago about how the moving molten iron in the magnetic field produces current (with heat as a side effect), and the currents (electircal and physical) in the iron produce the magnetic field. (tested by spinning molten sodium in a magnetic field) Another paper from about 5 years ago did a decent job of showing that the movement of the magnetic poles is due to gyroscopic progression. Both papers would have been re-printed in the AAAS magazine since that's my primary source for peer-reviewed papers, I'm sorry I don't remember what issues they were in, or the titles of the papers to make looking them up easier.

(even if it's in mineral form) If you're talking "maximum Isaac Arthursday thinking", you orbit a mass at least 20% of the mass of your planet so you can control the planets rotation speed and heat the core through tidal heating to kickstart almost any body with a metallic core.

[@CartoonHero1986]

I think it was Kurzgesagt that put out an interesting video with a concept of terraforming by using high powered lasers to bring the surface the planet to a molten state a few times over to liberate gases needed to create a primitive atmosphere, after this process is done using the laser one last time in a pulsing function to turn the basaltic planes into regolith, once cool enough it is theoretically just a very slow and EXPENSIVE process of introducing more and more complex life from Earth's biosphere as the new planet becomes more and more like modern earth. The process would likely take thousands of years from start to finish but consider the billions of years it took our planet to create these current conditions; that's pretty fast it also allows for tweaking and resetting the process if you make a mistake so the "learning curve" of that planet's reaction to terraforming will be more manageable and less likely to go into a runaway climate of cascade failure when human activity is added to the stress on the biosphere.

Most realistic option would be controlled bombardment of Mars and it's moon with stuff taken from asteroid belt, to create a proper magnetic field. It would take probably centuries, but at least we have tech to do that, all these other options are simply not existing at this point.

[@verdi2310]

Covering large areas of a planet surface with connected habitats is probably easier and cheaper than terraforming, if we have a really efficient anti-asteroid impact technology.

[@maxwest9470]

Or perhaps a large interconnected Pilon system that can statically contain an atmosphere of desired composition spread out over nearly the entire planet that way anything besides a large asteroid strike wouldn't be a problem orbital Point defense systems can take care of the rest

[@andrewgraziani4331]

Dome as you go, but seriously do we even need that much planetary habitation. Think about it say you are extra celestial colonists, you've probably have spent years possibly generations in a space habitat. The idea of living planet side might be completely foriegn to you.

@@andrewgraziani4331 I'm referring to mars and other solar system objects. I never get too exited about the prospect of humans colonizing distant solar systems. Because i think the speed of light is a limitation impossible to avoid. Also, knowing the human nature, its unlikely that any colony that take years to hear a phone call from earth will obey any order coming from us. No doubt they would be independent in the minute they put their feet on a distant planet and will become aliens for any practical purpose.

Hi Isaac. Thanks for the thought-provoking episode. Can I ask: you mentioned that we'd probably know a lot of facts about the target planet before we leave Earth, like length of year, length of day (and the knowledge of whether it's tidally locked to its sun or not,) and its mass. Can you explain the scientific basis on HOW we would know these things please? I have a rough idea when it comes to length-of-year, but it seems to me that most suspected-to-be-rocky exoplanets are too far from Sol for us to get any kind of a clear look at, so we don't know it's diameter. There might be a haze around it when it transits its sun, so perhaps we know that it has an atmosphere from that, but how would we know how big it is or whether it's comparatively low or high-mass? How much data of that nature do we already have about currently known exo-planets? Do we, for example, have all of that data on the Centauri system planets that are closest to us, and to what degree of certainty? And were the data confirmed experimentally?...

[@massimookissed1023]

I would assume we could send a probe faster than a crewed ship, and get more info from a probe passing a system than we can from observations of it made from around Earth. We could send probes off to many places before deciding which ones to send humans to.

Fusion gives you a lot of energy for very little fuel. And if you can effectively radiate or conduct heat away, the water for driving turbines can be recondensed in a closed loop system.

Why not start with Venus? We either tug, double and or teleport an Ice moon from Jupiter like Gliese in Venus’ orbit. Dousing Venus with water alone would manifest stronger magnetic poles than that of Earth. Teleportation is very similar to antigravity and doable.

I'm not a physicist, but I still had an idea recently for a "Portal Drive" that would allow us to travel between stars... IF it works... Though it does have a "What if" or two... What If... we discovered a way to make wormholes, but they were too small to be useful for regular transport... And What If... gravitational fields could be transmitted through such a wormhole... And What If... you set up a wormhole generator next to a large gravity well, like say, the sun... And What If... you had a ship that could project the other end of that wormhole ahead of itself so that it would be pulled toward the gravity transmitting through the wormhole... (I hope that made some sense) I know there would of course be some caveats, even from my limited understanding of physics... Such as the fact that the wormhole would Have to be Projected From and Not Connected To the ship... And it still probably wouldn't work... But my thought was that the ship would project the wormhole opening ahead of itself... Projecting the gravity well from the other end of the wormhole ahead of the ship with it... Which the ship would then "Fall" towards... But, because the energy used to create the wormhole was moving at the speed of light... The wormhole opening would still be projected ahead of the ship Faster than the ship was falling... Thus the ship and the wormhole it projected would move through space... And as long as the ship moved slower than the speed of light, then it would just keep falling through space... Until you reach the mid point of your destination at which time you would move the wormhole from in front of the ship to behind it... And the best part is that you could power the whole thing from the star side of the wormhole. Plus, if the worm hole was big enough for transit, you could set up another station at the new location... Or make the worm hole projector on the ship modular and just drop it off next to the new host star... And then have near instantaneous travel between the two systems... You would just use the Portal Drive System to make the initial journey. But of course if the wormhole collapsed, you could be hopelessly stuck between star systems... LITERALLY in the Middle of Nowhere... (So thank God for inertia...) (And an alternative means of slowing down.) OK, so I'm sure I've got a big bag of Nothing here other than the whimsical sci-fi fantasy of a nerdy guy with two AAS degrees... Neither of which is in physics... (Just to point out how much I Don't know) So you tell me, what's wrong with my idea and just how far is my "hand (or head) up Yoda's back side?"

[@lukehahn4489]

[@dmichaelbruce2819]

@@lukehahn4489 Actually, all of my degrees are in computer science, but nothing in physics, as I stated at the start. I based my idea around one theory of how UFO's travel, which is by projecting gravitation fields in the same way that I described... Paired with a few other theories I've heard about in other aspects of science/fiction. But That's also why I said the idea has a lot of "What If's"... Such as any issues arising from it being a closed system... of sorts.

Terraforming a planet would a difficult task but certain planets where their extreme weather patterns. A planet where it rain glass sideways due to extreme fast wind, planet where it rocks from the sky and plant where it rain lava. Another example where it it rain liquid iron mix with the gravity of planet will effect humans Jupiter like gravity too strong for humans to survive.

Seed Ships and habitats would be on the top probably but without diving too much into clark tech , what else would fall into this massive category ?

so, what about planet building? im thinking you send the miners in first, they melt down asteroids, taking what they want, and dump the waste into a gravity held "pile". with enough mass to that pile, it holds a round shape, and they didnt bother to let it cool, so it is a semi molten mass, that would hoover up gasses and the like. dropping more waste, would keep it hotter for longer, letting a core form from the left over metals and the like falling through the gravity well, while it is still molten enough. at what point should they stop dumping in that planet, and dump elsewhere, letting it cool enough to be colonized? what would be the best method to deal with a planet made of mining waste, when there is so much more use, for more, by that era? anything with high mass would have sunk to the core, helping to keep a magnetic field of some kind. or, would it be better to give it enough moons to shade it from the local star? options, options. a bit to explore on the topic, right :P

[@DrewLSsix]

I have to wonder what the motivation could possibly be for terraforming a planet in another system? First, such an attempt is not likely to be initiated until the original system has a well established space infrastructure, including substantial habitats. Such habits being possible candidates for the ships themselves. This being the case its likely that many if not most people headding out will not have had any time on a planet already and be perfectly happy on a habitat. Next is that unless stasis or life extension is a significant thing, the people that arrive at the target system are likely to not only never have set foot on a planet but to have no direct experience with people who have. Lastly, even a modest project will take centuries, in that time the colonists will have spread out, built new habitats and facilities, even if just in support of the terraforming project. By the time the planet is livable not only are we likely generations removed from anyone with any experience or desire to live down a gravity well, but it's likely that the systems population will be too great to fit comfortably on said planet. Meaning that on day one you have the kind of population issues that we imagine would drive colonization to begin with. To this whole project will amount to a pet project that a few people at a time might actually enjoy or have any interest in, and the population of this planet will always likely be a minority amongst the greater system. The motivation seems like it would be lacking at some point along the line, surely the people doing the work at some point would suggest that time labor and material could be better spent supporting the growing population and their habitats?
