- What if humans were born and raised in space? What would they look like, what health problems might they encounter? I take a scientific look at The Expanse and find what all fans already know...it's brilliant. [no spoilers]

I could’ve gone into a lot more detail about each topic and I already chopped out about 5 minutes. In reality it’s more complicated, especially the skeletal growth. For example, paralysed children who are bedbound from a young age still grow to a fairly normal height. Bedrest is used as a cheap Earth-based analogue for microgravity, but there is a fundamental difference between this model and the theoretical effects of literally growing up in space, namely that children will be mobile and likely to suffer repeated fractures of their osteoporotic bones.
Also, I know Belters might spend good portions of their lives in environments with low, but not absent, gravity, like Ceres. We don't know if there is a cut off at which point biological processes are affected. Some gravity is better than no gravity, but we don't know how much we need to stay healthy. How fast would we need to spin the Behemoth? No idea. For simplicity in the video, I just talked about weightlessness but it's likely to be a spectrum.
Ganymede’s magnetosphere is mentioned as a possible reason it is more suitable for human colonisation. However, its close proximity to Jupiter, with a much stronger magnetosphere, might make this irrelevant. And yes, I say “mag-neeto-sphere” because it sounds like Magneto and that’s COOL so shut up.
Happy to discuss further in the comments! Don’t forget to subscribe or I’ll sic the protomolecule on you.

Oye! With the hype for season 4 building I thought there might be some new viewers so just a brief note to say yes I know most humans in The Expanse would've experienced *some* gravity, so this was more a hypothetical worst-case scenario to see what might happen. Plus there is slightly more research on 'weightless' microgravity than 0.3g. I wrote a little more here in this thread from Daniel Abraham if you're interested www.reddit.com/r/TheExpanse/comments/91xed5/a_doctor_talks_about_the_biology_of_the_expanse/e322frx/
Could you do a video on artificial wombs? Like the one used for the sheep that died but ultimately grew long enough to grow wool?
Love the channel.
P. S. Would you entertain a job offer from SpaceX if given the chance?
@Benu_Bird Well spotted! I think I got it from Redbubble.
Darn you!! I've been trying to resist the temptation of buying the books! Argh! Sigh. Yes. It's worth it.*
*says the woman who read The Martian aloud to her primary school children to avoid salty language (they were fine with the science) twice before she realized that Andy Wier wrote a non profanity version. My kids are the kind of smart where you needed to be careful of their influences.
Your Belter sounded spot on.
Belter on drugs
😂😂😂
"Mi pensa" my man knows his stuff ;)

But, the belters doesn't live in 0 g outside of space excursions. They live on colonies where the gravity has been strengthened by rotating the rock. 0.3 g seems to be the standard level of gravity where it's possible.
True - discussed this in a bit more detail here: www.reddit.com/r/TheExpanse/comments/91xed5/a_doctor_talks_about_the_biology_of_the_expanse/e322frx/
Rev BladeZ Honest answer, we don't know. But from very preliminary evidence based on partially suspended mice (ie they hang them using little jackets so they're around Martian gravity, obviously it's not perfect) yes it probably makes quite a big difference
All the talk of Belters and g-forces actually made my thoughts circle around from space to biology, to space mechanics again; since Belters are undeniably weaker and more fragile humans than Earthers, does it actually make sense that they (and the Martians) are better spacers than Earthers? Think about it from a military context: the limiting reagent for how much delta-V you can apply at a time isn't the ship's drive-- the Epstein short demonstrates that the engine is clearly capable of performing high-g burns for long enough to kill a human-- it's the level of g's your crew can take for an extended period of time without suffering ill effects.
No matter what goes into the juice used to sustain humans in high-g maneuvering, all the benefits of the juice apply equally to the base human biology, so all things being held equal, in a maneuvering race between an Earther ship, a Belter Ship, and a Martian ship, the Earthers will actually come out on top every single time. They do explain that Martian Marines train under 1 g burns all the time, but they don't *live* in it, and the character who says that line inflects it like it's something impressive, so it's gotta be impressive to the Martians.
Just something that came to mind.
Cook
Yup it's said many times in the books that belters can't withstand higher g's well, they are however better at maneuvering in a zero-g environment.
Technically even belters on space excursions spend most of their time in some degree of gravity. The Expanse has torch ships thanks to the Epstein drive, meaning they're efficient enough to use constant thrust throughout the trip: speeding up all the way to the half way point, and slowing down until they reach their destination. This is why they only enter zero G when a ship stops. So belters travelling spend most of their time at however many Gs their ship's drive can sustain without running out of the fuel before the end of the trip, which appears to still be quite a bit less than 1g based off how things are presented in the show.
Awesome video! Tom Scott led me to your channel, definitely not disappointed.
I only looked at the numbers of this channel ~20h after Toms upload but even since then over the last hours this channel has gained 2k subscribers (fully deserved if you ask me)
@@miallo on sunday he hand 7,5k, now, on thursday its 22k, amazing! and so much deserved :)
Huh. Was from a Joe Scott vid. And I was from Scott Manley before that.
Oye, beratna! Dédawang ta xélixup!
10/10 on that creole. Easily one of the best videos I've seen recently, im da sheng. Looking forward to some more quality content in the future. Oyedeng, bosmang.
What the?
Ellenor Bjornsdottir , you didn't hear him using Lang Belta in the video?
@@thorr18BEM I don't know of it
I am a simple human. I see Expanse, i hit like!
It has been a recent binge! I passed a few years ago but coming back i like it.
I am an Arthur C Clarke fan so i think its very similar if not borrowing ideas of extrasolar tech from a dead civilisation, 'ascended' people coming back to talk, big cylindrical habitat ships hmm. More focused on the human 'geo'political situation which Clarke is quite sparse on human interaction and makes A.I. main character in space Odyssey hah. It has a post-millenial aesthetic too, also reminding of Nostromo from Alien and the briefly explored world in that film before the alien is discovered.
Not a lot of true Clarke media. 2001 was good but more like Kubrick acid trip. Expanse reminds me of 2010. Both get the science pretty right, the hihh G gravity assist in that is a foreshadowing, before monoliths...er...do a thing, like the protomolecule (no spoilers)
Hard Sci Fi ftw! I believe the more good hard Sci Fi books are made, and made well, into movies and especially series, the faster we will push into the future. No time to waste, inwards and upwards!
Amazing work!!! I believe that treading the line between science and imagination can lead us to great and unexpected things. As a historian, I can't help but think it's a good thing we have a long road ahead of us before colonizing space: we still have too much to learn from each other, to be wiser and kinder. Otherwise, that's something else the Expanse would get right... we would just reproduce the problems we already have in a grander scale. Love from Brazil!
I was just thinking about the possible conflicts and wars between the old Earth's humans and the new deformed space humans. Be ready for the SPACE NAZIS!!!
This is amazing - please do more!
Started rewatching the expanse again, before Season 4 hits and stumbled upon this video. It has criminally low views compared to how interesting and fascinating it is. Well researched, deeply knowledgeable and presented in a compelling manner. Also 10/10 Belter accent
7:16 Matt Groening got to produce the mission patch and he put Homer on there instead of Bender or Fry?!
Ejaculation, after all, is at its core just a primitive form of bending.
Homer was an astronaut, though, remember? “In rod we trust.”
@@nickboylen6873 yeah, but Fry went all over the universe, even to Hell.
This has got to be one of my favourite videos on RUclips. I've subscribed to you.
This is great, I can already tell your channel is going to flourish
Great stuff! Please keep it up. I studied for, and for 20 years practised, aerospace medicine as a specialist although the latter was confined to civil aviation. I am now retired and will only ever enjoy space travel vicariously, so enjoyed all 6 series of The Expanse enormously. Without revealing spoilers, there are scenes that somewhat stretch credibility in dealing with characters being "spaced" by exiting an airlock without full pressure suit. One main character in particular survives by reaching a nearby ship. I look forward to your comments on this in a later episode of your channel. 😅
lol that dead space reference is gold @8:14
Thanks for an excellent and very informative video. Compelling content and your presentation style is very engaging and fun. More please!
Great video. Going to have to keep an eye out for your other stuff.
these videos are brilliant, i think this channel has the potential to be the largest medicine-related youtube channel
Thats was a quite funny impression, well done with the video. Thanks for sharing
Damn. You're insanely smart. Thanks for the phenomenal vids. Entertaining and educating: Such a powerful combo ❤❤❤
What about treating wounds in 0g like depicted in season 3 and book 3 ?
Would it be as difficult as they describe and why exactly ? Just a suggestion for another video, this one was great !
Coagulation is a _bitch_ in zero g. Body fluids also pool in unexpected (for an earther) places. We do have fast-acting coagulants but applying them correctly can be difficult enough on Earth
Oye kopeng! Your belter was good. New season soon HYPE!
Excellent work. Has become my favourite channel
Came to your channel from Tom Scott, didn't expect this gem! Great video!
Thanks for tackling this topic! great work sir!
Zero gravity has multifaceted problems. Good thing that providing gravity in space is brutally simple: spin the spacecraft or habitat. The simplest, proposed by Robert Zubrin, is the bolo spacecraft wherein the crewed component is tethered to a dumb mass like an expended rocket stage and set to spin around their common centre of mass. Once spun up the gravity is provided with no additional energy inputs.
The Epstein drive of The Expanse is very likely to be impossible, demanding almost perfect matter to energy conversion and rocket reaction mass velocity very near light speed. Both demands will almost certainly vaporize any possible rocket engine.
Fascinating Jim! A really interesting video and it's nice to know that the creators put some thought into the biological side of things as well as the tech.
Engineers may dream as much as they want. Anyone with basic understanding of anatomy knows that rotating space stations are the only long term habitats outside of Earth.
Yep. Babylon 5 is da future!
Big and expensive.
Stephan's wrote about bolos... Two studio apartment sized hab modules, launched as a single payload each, cabled together in pairs doing the dance...
Who the hell holds a degree in spacemedicine? I mean doesnt NASA beg you everyday to work for them because its so rare?
Ha, NASA, ESA etc have far smarter people than me working for them! I have met quite a few professional space doctors, both in training and those at the top of the field - including one astronaut doctor. They are amazing people. I am just an amateur enthusiast with a pretty mundane day job. Once upon a time I was keen to pursue space full-time but life gets in the way!
Medlife Crisis
Well to call being a MD a mundane day job is I think even more humble than the statement before lol.
I dont think they only employ people with >150 IQ or something and you seem to meet all the standards to be considered very smart but I get what you are saying.
For people like me becoming a MD, let alone a space doctor, is hard enough haha.
Good luck!
@@MedlifeCrisis Damn, I honestly thought it was a joke when you mentioned having a degree in space medicine; I didn't even know such a degree existed. That is amazing.
OMG!
I already really really LOVED this channel.
I DID NOT KNOW you’d done vids on the expanse!!! The accents! I’m done!!
👌🏼👌🏼👌🏼👍🏼👍🏼👍🏼🙌🏼🙌🏼🙌🏼
great video, thank you for sharing
Love this channel! And you led me to Tom Scott, congrats!
The spin gravity of Ceres in the Expanse is higher than the gravity of Ganymede.
gosh i just love beltalowda and langbelta
This channel is a gem.
Thanks again mate, would love to hear more about the spleen, islets of langerhans and type 1 diabetes. Maybe something about proteins in there . Loving your videos, wish there was more ive ran out.
OK, so Martians don't grow up in zero gee, and for the most part neither do belters - both spend most time seemingly around a third gee. Now, while we have some significant data on what zero gee does to the adult human body, we have virtually none om the impact of low gee - having only had 12 people experience and never for more than 3 days. Nor do we have much data on impact of corealis effects of "spin gravity". Would be very interesting to see where the break point is for health human development - we know it is somewhere between zero and 1 Gee, but while creating 1 gee by spin is pretty hard, 18% (similar to the moon, would be fairly easy. Love to see some experimentation on this! Great video by the way!
“All that studying... for RUclips video...”
XD Amen. That’s a subscribe, sir!
Well, that was delightful. Been watching The Expanse for a while and just came across this.
Loved the Trekkie t-shirt.
After spending a month locked in my room studying for my nursing registration exam/the boards this took me from feeling vaguely stockholmed by my habit of read/watching medical-educational themed media (medutianment, if you will) in my free time to reminding me why I'm interested in medicine and science and how cool and interesting and beautiful it can be. This and the Sherpa video brought me into a fascinating new topic and explained it in a way that was accessible but not dumbed down feeling. I'd heard at some point in nursing school space nursing was a thing that existed so it's interesting to get a hint at what medical considerations go into providing care for people that go into space.
By the way, Russian cosmonauts say that there are no problems with the "fun" part of the sex in zero-g. It is quite a popular question to them :D Also, back on the MIR some cosmonauts were indeed asked to collect sperm. I don't think it's a myth, because why not.
Have not been able to find any women astronauts talking about it, though. It's not like there are many women cosmonauts in Russia and it appears that the NASA *really* doesn't like those questions.
There's a rumor floating around the internet that there's supposed to be a "secret" NASA videotape made during a space-shuttle mission in 1996 where two astronauts are trying out different sexual positions to test if they "work" in 0G. I remember The Guardian published an article about it a while back.
So yeah, I don't doubt they experimented with 0G sex already. One of the main goals of what we're doing up there is to understand if/how humans can function in space for extended periods of time, so obviously procreation and sexual release are a very valid topic for research.
I must admit that it looked pretty hot in the Expanse when they were having sex in 0G, but if you start thinking about the actual "mechanics" of it... I can imagine it's not quite as easy as some sexy lady riding cowgirl while floating mid-air, more likely it would involve both partners getting strapped in to some "sex-machine" type of monstrosity :)
@@runi5413
"sex-machine" type of monstrosity - lol'd
@@runi5413 kind of remember an article about that topic. I recall that they had some tube they both moved into to keep them close together and support the activities.
@@thankyouforyourcompliance7386 Yeah, that does sound like a reasonable solution to the problem... They have all kinds of exercising equipment like that on the ISS already. I can only imagine all the ways they are using those 🙂 (seems like total BS that this is still a 'taboo' subject, anyway)
Hopefully, SpaceX won't be as timid as NASA is to test out the whole sex in space thing.
Incredible video, keep it up.
Wel tanks very much for sharing the fruits of your studies.👌
so I've been doing exercise while listening to your videos because being in the presence of a cardiologist is excellent peer pressure :P
6:50 i died xD
But on another note daamn this is a great channel, i have been looking for more youtube channels on medicine but i only found chubbyemu and you now. Well there are some documentarys on medicine topics but they mostly just scratch the surface and almost never dive into say chemistry.
Great stuff, keep it up 👍
Remember the Cant
Would love to see more on the subject!
I love the fact you mentioned Wallace as well as Darwin
I liked you before this video. Now I've subbed. The Expanse deserves this kind of serious exploration because the creators have obviously taken a lot of trouble to ground this in as much realism as possible.
Awesome vídeo! Tnx
I really enjoyed your video. I for one think it was worth the degree. I like people who are smarter than me. Facts are the best.
Cosmodafinil :D
Nice!
Anybody else spotted that one?
Great video!!
Fantastic video - I want more! For example, what sort of evolutionary/genetic/technological measures could be taken to prevent or mitigate these problems?
What sort of experiments would we need to do to learn more about these problems?
What environments would be ideal from a medical standpoint for humans to spend their lives in?
Thanks for making such interesting and accessible content!
Btw - shared this video and your standup set with all my friends with a love for futurism and hard sci-fi.
I don't know if you're familiar with Isaac Arthur - his channel (a pseudonym, of course) focuses on deep time and humanity's place in it (along with other life). I would be keen to hear your take on similar subjects.
Ok, I’m back. This video is like returning to my undergraduate years or having a study day on a GP update course. It’s great that you’ve found a way to use that space medicine degree. I’m now off to help access into primary care within the Jewel that’s our NHS, to keep offering free healthcare at the point of delivery. Beltalowda
Interesting, awesome doc
Great video - subscribed!
🥰🥰🥰 you did a video on the expanse!! 🥰🥰🥰
Not related to microgravity-related health problems, but in the book _Dune_ by Frank Roberts and the second and thrid installations, the Fremens are a people native to the planet on which much of the story takes place: Arrakis.
Arrakis is extremely dry and as such the native population holds water in high value. The Fremens have developed physical adaptations to reduce water loss as much as possible. One interesting adaptation is their blood, which clots much faster than human blood to prevent water loss in the event of an open wound.
Just thought it was interesting since we're talking about sci-fi and adapting to live in alien environments.
Brad Partain I think this is quite relevant to the video - like the Belters, the Fremen had to adapt to the particular demands of Arrakis over many generations. And as you said those demands ended up influencing their culture as well with its particular emphasis on water. The Belter’s culture was also impacted - their language is a good example of this. The demands of living in space enforced cooperation, and that resulted in intermingling of their languages. There is also some cultural aspect to their tattoos, if I recall they are harkening back to an earlier (worse) suit technology that left marks on their skin that were similar to their tattoos. So that’s kind of like a shared cultural memory of a traumatic event.
Also, thanks for leading me down a rabbit hole of what it means to be “native to” someplace. The Fremen came from another planet, so I didn’t think they could be called “native to” Arrakis. But after further investigation of that term, and related ones like “indigenous”, I’ve realized it’s all pretty vague. The Fremen as they are described in Dune are probably so changed culturally (and probably physically) from their original people that they may as well be called a new group that is native to the planet whose conditions shaped them.
@@noahmccann4438 every human in any universe where earth exists is native to Africa then, /s
I’m only 1.42 seconds into this video. But you’re my hero!! Speaking as a doctor myself for the last 20 years, graduating from London and Gp’ing in the shires for the last 16 years. I’ll drop another comment I’m sure as the video progresses. Oh, and Donkey Balls, Hoss!
You are hilarious! WELL DONE!
Therapist: Medlife crisis speaking in an American accent can’t hurt you
MEDLIFE crisis speaking in an American accent: 👀
Excellent video, also very funny!
i though belters live in low G enviorement, not in zero G enviorement, Ceres for example, had rotation gravity for his habitants. another thing is that any internal hemorrage in space at zero G would be fatal because without gravity, blood wouldn't run normally and blood clots would be impossible to stop before they make any damage
Mi pensa we are really getting SF tropes from the 1930s to early 1980s in The Expanse. So for me the show is more of a return to the excitement and hopefulness of my youth as opposed to the more fantasy-based mass market material we got when Hollywood stuck its oar in and confused comics and scifi with real science fiction.
OMG I cant believe you watch the expanse! I love the show.
This video is beautiful
If you aren't already in that field of work, please consider taking up education. I am a molecular biologist schooled at two high-profile german universities and I learned a LOT in just these 10 mins of youtube. Kudos to you. Great vid!
your kid's name is Amos? thats awesome!
I've seen this vid from way before and I just noticed your shirt.
"Damn it, Jim!"
The episode 1 hooks scene is meant to show belter anatomy they couldn't do the different anatomy throughout the show because it would have been difficult and expensive.
All that studying for an RUclips video.... EPIC!!
Damn it, Jim!
Belters (and I think Martians as well) get growth hormones and medications that help prevent the majority of the major side effects of the low gravity living, though it doesn't help everything. The show even shows this with revealing the back of Miller's neck. Great video though, I really enjoy it when anyone talks about The Expanse, or growing in space.
Sucks that The Expanse is only on Amazon Prime
So babys should grow up in a centrifuge?
All people in space should live in a centrifuge. Tycho Station is how you live anywhere that isn't Earth.
I would love to see a video about 2-3 generation long travel at high speed in a city sized space ship, maybe use the old juice for one more?
Im a medical student that's obsessed with sci fi, especially The expanse. I hope to get into Aero-medicine!
Instant sub
Would kids still have the bone deformities in their legs if they wore the mag boots they have to on more space stations in the expanse? I’m assuming the bowing is caused by the weight of the upper body on the weak leg bones. If the feet are firmly planted on the ground and 0G keeps too much stress from going on the legs, will they have relatively normal growth?? Would love to hear other’s thoughts!! Awesome video, man. I love all the amazing world building the creators behind this story did.
Topics for next videos: bleeding wounds in zero G, prolonged high G effect on human body, microbial and bacteria life likely to develop in zero G. Plant growth. Great video man.. amazing. Almoast skipped it because the intro, while nice, didn't point to the type of video it is
Fascinating and... hilarious at times. This channel is definitely my favorite medical channel next to chubbyemu. Pity I've discovered your channel so late. I've been fascinated by human body and its complexity (especially the brain) since I remember, but unfortunately missed my chance to study medicine and went I.T. route 😂 That being said, I love to watch medicial stuff and google the shit out of every word you (and other medical channels) say to understand it better. By the way, wouldn't rotating spacestations solve the gravity problem? I know that with centrifugal force there is still Coriolis force, but I have no idea how it would impact the human body and I don't know if there ever have been any research about it. Would be great to hear your thoughts on this!
I think the words of Kennedy, altered slightly are fitting here. "We choose to go into space and do the other things, not because they are easy - but because they are hard".
Humanity, as a species, has always thrived when we've had a horizon to try and headbutt. We've stagnated ever since the moon landings, since we headbutted the last horizon we could think of.
... I guess that might be related to the bit about low birth rate among the Coordinators in Gundam Seed as well
very good idea for a video.. literally no one talks about medicine in zero or low G
That intro!
Fantastic video.
What's your opinion on gene editing to adapt to the harsh environment of space?
What an interesting and informative video! Also "toot my own rail gun"... I'm howling, lol 😂
you're crazy, I love it
Lol, when I watched a few of your videos, I thought that you might as well be a space medicine researcher (or something like that), but I thought it was just because I'm kinda biased :D (it's probably your space posters)
🤔🤔🤔🤔🤔🤔
Maybe you'll get to it some day :)
I’ve never seen the show but my best guess is that the juice is at least somewhat inspired by the HANS device
I've wondered for a while whether it would be more cost effective to spend a portion of your day in a small hyper gravity chamber and spend the rest of the time in near zero g?
Unitology is the future. Altman be praised @ 8:15.
Make us whole!
I wonder what the tech of creating normal g environments on stations out there might be? Then the problem can be at least partially solved...
Rohin you crack me up
omfg I just wanted to watch "The Expanse" extras and whatnot and now my brain is squeezing my nuts as I writhe on the couch.
9:53 Don't Miller and Holden have a kind of permanent cancer treatment for their exposure to radiation on Eros?
How good would space feel for chronic spinal pain conditions?
8:15 dead space necromorph reference. Hilarious 😆
Maybe a subject you could talk about: at 8:53 we see a needle-less injection, it is often shown in sci-fi, but is it even possible and is there even some benefits?
I've been thinking about a Star Trek medicine episode, might be a while away as no time at the moment. However, I can tell you now that we already have needle-less injection! It uses a gas powered injection of liquid at high pressure which goes through the skin.
@@MedlifeCrisisthanks a lot for your answer! :-)
But has that some advantages and can it deliver the medicine the right place?
