10 Future Technologies Useful for Space Colonization

[@brick6347]

The last few years have taught me that it's really no fun living under the thumb. Personally I now find the idea of living in a space habitat pretty troubling. Someone is going to own it, be it nation or a private company, and I'm guessing most people would just be a renter. The idea that the _terms and conditions_ can be changed on a whim.... not my cup of tea. It sounds like a place with the potential to get pretty despotic, pretty quickly. Plenty of advanced countries have gone lala at some point.

[@Giganfan2k1]

What if you owned it yourself? If radical life extension is on the table almost everyone today could be a ruling class that knows what living under a ruling class is like. All that would take is a few good investments. I bought my own house in 2017, making under $11 an hour. I worked at a job for a 8 years putting between 10-20% of my paycheck back in my 401k. A lot of 401ks have loan programs. That give you access to your savings to buy cars, property, even help you start a business. Looking into the future I do not see any reasons people in their 20 to 30s shouldn't expect to live until they are they 150 - 200 years at a very conservative estimate. Saving and compound interest would allow you to outright buy a cylinder even if you just had a day job and aggressively saved.

I was thinking about people doing space stuff In the Earth's ocean, including these generation ships My city nex to the beach, it looks natural to expand to the next density atmosphere Practicing for generations Epigenetics, people better able to deal with 0g And the life is quite alien, we can treat it the exact same way

What is your take on self sustaining spaceships, space stations, moon stations, underground or both above and below, mars stations,( implications for astronomy and asteroid research, one of civilizations largest threats)small research stations or cities. And what implication do you think this focus for space exploration and expansion, and the self sustainability demands has/will impact civilizations on earth. In terms of eco system designed food forests, desert greening (easier than terraforming a planet like mars) , general food forestry, vertical farming and winter greenhouse culture, earthships etc..look up the work of Geoff Lawton, Michael Reynolds, hear out desert greening TED, little inventions like the waterboxx - how can it be optimized(?)

[@realzachfluke1]

I freaking _KNOW,_ RIGHT?!?!? Like for the video that came out right before this one (or possibly the next one further back-sorry, time is so screwy right now for me, but it's not actually important lol), I had started listening to John's sleep and relaxation playlist to wind down for that night, though not before checking the uploads page and finding that I was indeed up to date (no new videos), and just let it shuffle. A few videos had gone by, and as the next one was playing, I started thinking that it sounded like I was listening to a JMG video I missed, but I was chilling out and really enjoying the video while being comfortable in bed, so I didn't immediately check my phone to see what was up. And shortly thereafter, John starts talking about the James Webb Space Telescope having been successfully launched into space by the Ariane rocket, which of course it HAD, but like I said, I checked the uploads before I fired up and shuffled the playlist and there weren't any new ones. So at that point I get up and find that John had _definitely_ uploaded that video shortly after I started listening to the sleep playlist, and since he also added it to the playlist I was on, I got to be completely surprised by it! I definitely appreciated that hahaha, and that was only my story about the _last time_ JMG's legendary video timing really stood out for me, there have absolutely been plenty more before that 😂😎

[@jdiluigi]

"Down and Out in the Magic Kingdom" is a fantastic story of a humanity that has integrated computer hardware into their biology so that they can back up their consciousness and, should they die, be brought back to life in a new body based on that backup.

[@mortimerhasbeengud2834]

Dense electromagnetic shields have indeed be proposed to feed off cosmic rays (gamma) + solar protons. Worth the energy expense. For human habs, lots of silicon, and iron out there to insulate from the previous zappers.

[@robbabcock_]

A wonderful episode! Some of the biggest challenges with regards to humanity's future in space comes down to philosophy- ultimately what will it be mean to be human? It's easy to speculate what a machine civilization might be like but much harder to emotionally wrap your mind around an existence like that. We're getting into transhumanism for sure. I can imagine an O'Neil Cylinder (however hard it may be to build) being created in such a way as to mimic the biomes of Earth, filled with trees, imported birds, flowers and simulated wind. And even on Earth we have tremendously urban areas where people don't interact much with nature. But while I love science and look forward to seeing what humans can do in the future, I think the biological components of humanity are a core part of us. There's no better way to understand this than to hike back into a remote mountain lake a hundred miles from the nearest electric light or human settlement. We can maybe remove humans from the Earth but if we remove the Earth from humans, do we still have something that's really human? Great stuff, thanks JMG!🚀🛰🔭🌌☄🙏

[@urphakeandgey6308]

Since you bring up transhumanism, what do you think about a scenario like seen in "All Tomorrows" where the humans, after colonizing Mars and diverging as two species on two planets and going to war, engineer themselves to be "fit for inhabiting the stars" or something along those lines. They turned themselves into "Star People" and inhabited new bioligical bodies. Seemed like the implication also was that they might've had a biological leaning towards peace, since the decision was made after a gruesome war between Earthling Humans and Martian Humans.

I suspect you've talked about it on this channel before, and maybe I missed it here, but no mention of active support? 🤔 I think it would've been worth mentioning for the space elevator segment or even a potential member of the list on its own! Enables things like launch loops too, or rail guns reaching much longer/higher to allow for slower, more biologically tolerable accelerations even from earth.

In the Red/Green/Blue Mars trilogy, iirc, one of the Martian moons is used as the space end of the Mars space elevator.

Combine the Dyson swarm idea with a shield for Venus, generating useable energy while shading Venus. The JWST has demonstrated how cold the shielded side can get. It would take centuries if not millennium to cool Venus down to Earth like temperatures. Using Dyson energy capture equipment would provide immediate benefits as opposed to the long period of changing Venus into a habitable world using a shade with no other use.

Late to the party, but if you wanna read good hard sci-fi with sky-hooks among other weird technologies, read Neal Stephenson's Seveneves. Actually even if you don't care about skyhooks, you should read it. It's long, and dense, so I wish I'd read the dead tree version instead of the audiobook (when he gets conceptual I often need to skip back a page or 5, or stop and chew on his idea for a while). It's really something. Also, do yourself a favour and avoid spoilers if you can.

[@Giganfan2k1]

17:16 where I see this kind of technology going... I think we make ecologies. What better way to protect Earth biomes than transplant rare and endangered stock than a cylinder? Or... You can create a bunch of experiments. Like build a cylinder that is mostly sterile. Then populate it with prokaryotic life and studying how eukaryotic life came about. It is one of the most important questions in how our planet got to where it is today. Or we could make large stretches of designer biomes. Where we tweak living ecology. Like what would it be like to live on a cylinder that had carboniferous atomsphere?

[@liberalrationalist8905]

One potential problem that perhaps no one yet is aware of. A study of children found that if they are asked to draw a "country" scene that they think is nice...what do they draw? An African savannah. Long term, a space colony may cause mental problems in the inhabitants. Especially if centrifugal force is used for gravity. If one doubts the possibility of mental issues developing, look up SAD (Seasonal Affective Disorder). A high latitudes problem of too little sunlight during winter. The problem I see with a lunar or Mars colony is too artificial, too limited environment. Picture the equivalent of a large prison system. We need at least a highly capable AI with total automation to construct a very comfortable environment.

[@bradleypoe6846]

YEP. Mental health becomes a huge issue once you start talking "space cities", whether under a dome on Mars (for example) or in an O'Neill Cylinder. Suddenly people start to need, long-term, far more light (to regulate moods) and space (for extra, discretionary activity outside of work-flow) than they'd appear to for short space trips. Essentially a space city's going to need to be at least partially run by an A.I. (since politics are as much a negative stressor as not), it's going to need its own theme park (recreation will be as vital as food and shelter) and libraries (with physical backups for both since ionizing radiation is a thing in space), and it might even need stout legal drugs (both clinical and recreational) just to help people reset their limbic systems from the constant stressors of *never ever going outside.*

[@eastindiaV]

You didn't mention Lagrange Points. There are gravity wells in between stars, so you could slingshot from star, to Lagrange Point, to planet, etc... just using gravity wells and celestial objects like a railroad. Would be more logical way of mapping space also, empty space is like the deep end of the pool, scary. Better to stay around the snack bar Slingshotting around a planet is like going straight if time is a line. That shortens the amount of time it takes to go a certain distance, by using inertia... so it is actually counter-intuitive to go in a straight line from star to star. Gravity and time are non-linear. They are a Cycle. So the shortest distance between 2 points in 4d, is like a circle I think, or maybe a figure 8. Every gravity field is like a speed accelerating arrow in Mario Cart, if used properly

[@bkparque]

Dude you forgot to include anti matter map with anti matter sail made of u238

[@alien8treker2]

I think the length of the elevator is less dependent on gravity than the distance to synchronous orbit. A Mars with a 10 hour rotation would require a much shorter tether than the 24h+ rotation it has due to the implied lower synchronous altitude. Please check my thinking.

[@madderhat5852]

[@ronaldgarrison5528]

21:10 The radiation on Mars is not going to be immediately fatal on the surface, even now. There might be a risk of ARS if you were out during a major solar storm, but I wonder about even that. (Feel free to provide correction on this point, in a civil way of course.) The bigger concern on Mars is GCR, but that's a long-term matter.

[@trumanshow162]

Industrialization expanded civilization, enabled by agriculture. Computers buffered the shock of reaching the global limit. AI will give us sustainability on the Earth. Then, what will be the next epoch-making technology for full-scale space development? Will it be useful new material, powerful new energy, or techs to improve human abilities or collaboration like BMI? I hope we can achieve sustainability on the Earth and build an interplanetary civilization.

[@trollking202]

Carbon nanotubes can now be manufactured in sheets.. I had to check the date on this video..

[@JohnMichaelGodier]

That was kind of a disappointment because it was sorta kinda sold as a major breakthrough, but wasn't. Yes, they are carbon nanotubes, and yes they are in very small sheets, but the function for the Fujitsu development was to transfer and dissipate heat rather than for strength. It isn't applicable for tethers, it would snap like anything else. Good for electronics in computers and electric vehicles though. Everything else touted as carbon nanotubes have been hybrids with other materials and are not even in the ballpark as far as strength.

Not to be That Guy, but... I would hardly call our current levels of space travel a "golden age". Considering that we've "only" put humans on our own satellite, one and a half light seconds from our planet, I'd say it's more accurately described as the "stone age" of space travel. Or, depending on your outlook on prior visitations and the origin of humanity, possibly the "Neolithic Age of Space Travel".

[@plaguedoc-vy4rs]

I would like to offer another point of view towards what was mentioned at 3 minutes and 54 seconds. I believe that the reason we could not continue to use nuclear propulsion is largely due to the fact that it was militarized and made into missiles for the larger nations of this world to point at each other. If we had used the original concept for nuclear propulsion but scaled it up as originally planned way back when, we would already probably have set boots on Proxima Centaurie's planetary system. Instead, we are just now getting around to sending tiny light sales. I hate to sound like a Debbie Downer John, but I think we got screwed out of our time to physically witness Interstellar colonization.

[@JohnMichaelGodier]

Wasn't much better in those days in a science capacity. There were some studies on using nuclear bombs as explosives to dig channels and things. It would have gotten the job done, but would have resulted in contamination as the weapons testing did. There are/were concepts for nuclear propulsion in space, which I mentioned, but that's probably going to have to be developed in space from materials from asteroids as opposed to launching those materials from earth. We did some really wacky stuff in the past with nuclear testing, such as Starfish Prime that left a bad taste in everyone's mouth in that failures and problems were not anticipated by either the military or the scientists. As such, screw it up once in a new effort, and it's done for on earth. In space, it's open game. But it took a whole lot of mistakes to get to this point.

[@plaguedoc-vy4rs]

@@JohnMichaelGodier and it will probably take a few more mistakes before we get it right. A little off topic, but can you recommend any good editors or illustrators in Florida?

The space habitats will allow humans to be able explore space and not need to find a planet that is suitable. To find such a planet will most likely lead us to life. These planets will also never be as perfect as a habitat we build ourselves. They will be our future in my minds eye.

[@50megatondiplomat28]

I'm very interested in the nuclear rocket engine that we put a bunch of work into in the 60's; and in fact, I've recently heard more work was going to go into it. It offers a number of significant advantages over standard rocket engines. And out in space; tons of radiation is blasting past you every second; granted, different types, but out in that vast expanse, you won't be poisoning anything. I think that until we miniaturize fusion (which Lockheed does have patents for), this is our biggest leap in tech available at the moment. The caveat here is the Pais patents which seems to be based on technology we may have recovered from non-standard sources. There are substantive rumors of high technology currently locked up in Black Project silos too. Of course, Ben Rich stated that "It would take an act of God to ever get them out to benefit humanity" (out of black project "silos"), but if that happens, we may see a quantum leap in capability. I've put years into investigating rumors like this and multiple investigatory threads seem to keep leading back to the same substantial sources. So I'm hopeful that this angle might bear fruit one day also.
