Colonizing space and settling the minor planets and asteroids may mean adjusting to much lower levels of gravity, or micro-gravity, what sort of biological and cultural adaptations might that require of humanity?

thanks for covering this. I always found it weird that by default you went for rotating habitats. I can understand how fusion reactors might not be possible or at least non-massive ones, but adapting to 0 G seems inevitable since it should definitely be possible under known physics and is cheaper than not being adapted edit: relistening to this. Damn, lack of gravity is far more harmful than I thought. No wonder you suggest rotating habitats to humans. On another note, only now I realize the weight of the audience you refer to, not so rarely being, people from the far future. You're an optimist as well, so it'd stand to reason that most cases of your content being watched ever will be by those in the distant future, thus it makes perfect sense to refer to them so often as a joke. Still, it's pretty wholesome.

Gravity wells will remain the large piles of resources and living space they are, meaning weighters will have the means to develop the needed megastructures to have easy access to space, and will have the energy budget to simulate gravity in their habitats. I wish good luck to floaters to reliably and cheaply simulate zero g in gravity wells. This asymmetry doesn't seem to count in favour of floaters, who would end up trading biological flexibility for the very effective yet incredibly dangerous path of fully adapting to space as a medium. Mass extinctions of species are full of dead species that were so well adjusted to their environment that any significant change wiped them out. That said, we could also take the opposite perspective and see inhabited gravity wells as the rarity, and space life as the interstellar norm, meaning weighters would be the ones being endangered. Could go either way, depending on how hard exactly is life in space going to be (we're still working with mostly 20th century assumptions about space life here).

@@lucofparis4819 If you're a "floater" you can just vaporise the planets to extract any material you need and create way more livable surface than a dense sphere can, not to mention that while planets are big resource deposits, most of it is inaccessible below a few kilometers. Even the "grounders" would likely dismantle every object in the system to create more living space and resources. Not being able to reside in gravity wells seems a lesser problem compared to having to spend energy escaping them and simulating them once outside.
@lucofparis4819
@lucofparis4819 3 года назад
@@Soken50 You cannot 'just vaporize planets', as the amount of energy required would be so large you'd be much better off spending that to land and physically pick the planet apart one layer at a time. The advantage of habitable gravity wells is that they're already habitable. No effort required (or so little in comparison). So it is untrue that they're somehow less interesting just because they're less effective in terms of available living area. As for mining deep within gravity wells, it's about dealing with compression, something active support can deal with, so we're not just talking about a few kilometres deep, but probably one or two orders of magnitude deeper, which offer circumstances where mere active cooling to render underground structures habitable would offer great geothermal power opportunities. Last but not least, the mere existence of floaters entails the existence of infrastructures allowing for cheap access to space from the surface, i.e. the associated tech would be already researched, proven and quite well refined in the era when floaters would begin to exist. Furthermore, these structures would be necessary for the development of the space infrastructure that ought to exist for floaters to exist and work, making them initially dependent on terrestrial shipments. The same would apply to rotating space habitat tech and mass production industry. So, it isn't so clear how these apparent problems would remain a dissuasive factor for future gravity well colonizations and exploitation. All this to say: I'm not so certain floaters would be so advantaged.

​@@lucofparis4819 You can 'just vaporise planets', it takes the output of an entire star and a few years, but you CAN. I take it you're not a regular of the channel ?Because melting down planets to access resources and create more living space is FAR from the craziest idea you'll encounter here, enjoy your stay. As for the rest, I don't have the energy to rebut each point as many were already adressed in the video. We can certainly overcome many of the challenges that gravity poses but I remain convinced skipping gravity entirely would prove more beneficial in the long run.

In the Vorkosigan Saga, there are the Quaddies, who were genetically engineered to have two sets of arms and various other adaptations for micro-grav. They were created shortly before artificial gravity was developed, and so are a minor, but large splinter culture that mostly keep to themselves in one corner of colonized space. Also, in a slightly less scientific direction, in the Gundam UC timeline, the "Newtypes" develop psychic (mostly manifesting as an ability to sense other people and their intentions, though some people are full on telepathic) powers as a result of "human souls no longer being bound by Earth's gravity".

I wrote a book that takes place in the 55th century. There's an incredible amount of space traffic in the solar system and many millions of people travel through space everyday. To avoid the problem of transitioning from gravity to microgravity and then back to gravity, humans have been genetically engineered so that their muscles do not atrophy. They've been engineered for a lot of other things too, both related to zero-g and other things, but that is one of the most obvious.

Great episode! Of course, as a "fan of the can," I think at this point the most crucial task is to make the first cylinder habitat(s), which we already know how to do, and we can sort out the subtleties at our leisure after that. Okay, here's my opinion. The first rule of warfare is: "You are already in combat. Nature is always trying to kill you anyway, so the only thing that changes is the most urgent opponent." Survival is an ever-evolving duel among checklists. Eventually, Time wins regardless, but the whole point of the exercise, the very meaning of life itself, is to make the bastage work for it; and to build some beautiful sand castles in the meantime until the long tide washes us over. With such understandings, we can proceed in communion and joy to build as much and as good of a future together as we can bring from our imaginations to our worlds.

Just gonna say, there is another option for gravity simulation in a vacuum. Since accelerating has the same effect on your body as gravity, angling your engine parallel to the floor of your space shuttle and setting it to 1g of acceleration is just as good as an O'Neill cylinder. If you are wondering why no ones done this before, it's because currently, rocket engines have very little fuel capacity, and can not afford to be under constant acelleration

I feel like the Expanse has ruined the idea of humans living in low-g environments for me. The idea of humanity dividing into strong normal planet dwelling humans and low-g lanky freaks that live on asteroids or whatever kinda scares me. That’s why I also prefer that Venus is the planet that is terraformed and permanently settled first as opposed to Mars since Venus has similar gravity and won’t produce such uncomfortable situations. But that’s just me,obviously setting up colonies on Mars first is way easier since Venus is literally hell and my view is admittedly based on my personal feelings on the matter and not in any objectivity.

The expanse is awesome but the way they portray belters is stupid. Nobody with 1/8th of a brain would live in a low G rotating hab when they can easily spin it up to 1+ G.

Mr. Dothe Twist , Any of these "spin the ship" or "spin-section" architectures will not be practical . They will be too problematic and weak ; providing inadequate gravity before malfunctioning . The practiceable and safe approach is to employ split-ships/tethered-ships . Either one of these designs has the advantage of providing a lifeboat , in case of accident or impact . They also provide full gravity for the entire ship , not just partial-gravity for part of it ! 😎 *To examine this subject in more detail , read my post at : quora.com/How-would-Martian-settlers-cope-with-the-lower-gravity-What-would-be-the-health-implications/

@Robin Yabanks maybe build the electro stim into clothes/suits? (A pressure suit doesn't need to be a full space suit, it just needs to keep you alive in case of emergencies. So I would imagine many would wear a minimal pressure suit at all times). Also there are some genetic conditions that result in too much bone growth/muscle growth. Those are awful to have on earth, but might be highly desirable in a controlled gene therapy in microgravity.

I want to pull you up on a small part of this that I find disingenuous. Most people have not gone to visit the grasslands of Africa were our ancestors came from because of a lack of affordability and amenities. Tourism to and from Earth and any colonies it might have would entirely be dependent upon these two things. Martians may well be very interested in visiting Earth as a tourist if it was affordable and they were able to withstand the increased gravity. As for why Americans haven't visited their ancestral homes in other countries, that's a cultural thing because most of us in Europe tend to do a lot of travelling to other countries both for Summer and Winter breaks.

I do think there's probably significant value in having artificial low gravity. Something like a 5 meter radius cylinder spinning twice a minute only generates about 0.22 m/s^2 at the rim, less so in the interior, but at least things can fall and gasses can separate from liquids.

In my all time favorite novel, The Moon is A Harsh Mistress, Robert Heinlein imagined that after more than a few months in lunar gravity, human beings could no longer live permanently on Earth. In the novel, the moon was a penal colony, much as Australia once was. However, it was a penal colony where the descendants of the prisoners could never leave. The over populated Earth, was also dependent on lunar farms for food. One man realizes that because the moon was sending so much water (from mined lunar ice) and nitrates to Earth in the form of food via electromagnetic catapults with nothing being returned (except more people) the moon would eventually be unable to support it's own population, much less Earth's. Teaming up with some friends and the (secretly) self aware computer than runs everything on the moon, they stage a revolution. That book features many topics that have been episodes on this channel. Isaac has not however done episodes (that I can recall anyway) on libertarianism or polyamory (2 themes present in nearly all of Heinlein's non "juvenile" novels), at least not yet. Maybe one of these days, because we all know 2 subjects that are never controversial are sex and politics.

I am envisioning some sort of 'gravity sickness' device, either a machine for one to enter or a small subsection of a rotating habitat. You are placed inside of it for a time, much like a decompression chamber, as it gradually ramps up its revolution rates and therefore gravitational effect. Instead of the light switch of gravity returning as you go slamming through a planet's atmosphere, put it on a dimmer and slowly turn it up before you even arrive. I could even see this used for sections of a larger ships, preparing portions of its populations to settle various gravitationally unique locations. Just spin the colonizing population's portion of the ship to acclimate their biology ahead of time...

Regarding replacing feet with hands in long term microgravity living; our feet were very obviously previously hands that evolution has (haphazardly) made into feet. I wonder if we'd be able to look at the genome of close relatives and potentially ancestors, and then try undoing that change. All sorts of potential ethical issues there I'm sure, but it's just intriguing to me that we could hit the genetic "undo" button a couple times on our feet and then have more hands for microgravity living!
@benjaminmiller3620

It's very plausible, maybe even "easy" (Or as "easy" as anything involving genetics can be.) We've done related experiments on flies that have turned their antenna (which are homologous to legs) *into* legs growing from their head. There are probably a handful for hormones during development that kick off the differentiation. I imaging the hardest part would not be turning legs into arms, but doing so while *not* messing up the rest of the anterior/posterior development. (It doesn't help if you have four arms, but no anus/genitalia/bladder)

Real close to 7 G the lights started going down (graying out) so I had to release a little pressure on the stick. But what fun it is flying aerobatics. I know it isn't the same thing but it is a small sample and didn't have to worry about slow heart rate or low BP for sure. I worked up a sweat every time. Great fun.

Nice episode and well made. These types of Space faring species may have decided to develop genetic multi-phonotypes like ants, bee and coral. Depending on the job that will be needed the queen or community will insert genetic instructions for that batch to take the shape of the needed mission, or environment. So staying forever adaptable. I also think it would be easier for those aliens that have carapaces or cepolid forms (like octopi) , to adapt to this type style of life. They might be the only ones traveling over vast distances to colonize. If humans become completely zero G oriented would they be unable to return to a gravity existence? In the same way species that live as deep bottom dwellers die when introduced to the severe lower water pressures near, or on surface. It would be interesting to see how naturally xenophobic species like humans would react to the new men of space.

Great video as always Isaac. This got me to thinking; why not take it a step farther? If you have cybernetics or advanced spacesuits, then you could get away without atmosphere too. Instead of inflating your habitats with air, you just use asteroids and the like for protection. You can use short range radio just like we normally use soundwaves, just make a wavelength range and associate it with sound. You would need oxygen refueling as well as food that can be consumed without removing your suit. Genetic modifications to remove hair growth and sweating could also be useful to prevent sores. A heat sink and radiators may also be needed. However, if these issues can be handled, then they could grab the low hanging fruit very easily indeed. They could literally carve homes out of asteroids.
