Can The Human Body Handle Rotating Artificial Gravity?

Can The Human Body Handle Rotating Artificial Gravity?

Artificial gravity for spaceflight is a concept older than spaceflight itself, but we’ve only ever seen one small scale test ever flown in space. However decades of research have been performed to show that the human body can adapt to the conditions required for rotating artificial gravity. This shows that it’s an engineering problem that likely solvable for interested parties who want to spend the time, effort and money creating the classic rotating space stations from Science Fiction.

Here’s a couple of papers which were heavily referenced in researching this

    Does everyone have to be strapped in when it starts? I’d think of you just start pinning from zero G, every thing will stay still while the structure spins, everyone inside will be crashing into stuff.

    WOW !

    I think the easiest way of explaining away all of the "intertial dampening" and arteficial gravity would be with some nebulous "effector" capable of imparting a precise amount of force from a distance, instead of implying heavily that the deck plating is somehow dense and massive enough to noticeably attract matter without the corresponding inertia. I do enjoy the visual of big rings spinning in different directions, but they aren’t nearly as practical for rapid maneuvers, though.

    I bet you’d also use a rotating facility for certain kinds of orbital manufacturing that would benefit from the stabilizing effect of constant g forces. Some aspects of manufacturing would be easier in zero G, but others would be rather difficult since you would have to design additional machines to manipulate and hold everything rather than relying on the constant pull of gravity. Conveyors would have to be much more complex in zero g for example. I can see some far future facilities with multi-level rotating rings for different g requirements and a stationary section, either separated but nearby or kept in zero g through counter-rotating motors.

  9. Robert Senger on August 26, 2021 at 10:17 pm

    Excellent video, I really liked it! Years ago I wrote a science fiction novel, Islands In The Void, which has a centrifugal gravity system with rings and shaft spinning on a fulcrum; the propulsion system is on the fulcrum and people live on the rings. I spent a chapter just explaining how the spacecraft worked. I hired an artist to turn my drawings into the spacecraft on that book’s cover, he was in college at the time, today he’s a very successful guy working for Hollywood. Always wondered how close my estimate was to its size, spin and gravity. Due to the rings of the spacecraft on one end of its main shaft, it’s a little more complicated. This was very interesting, I didn’t know about that Russian research, I wonder what NASA is doing with their current research in this area.

    There’s a massive difference between you on the planet spinning around on something where your body keeps on wanting to readjust to the gravity well also be affected by this other force. Two sets of inputs makes the body confused out in space you’re only going to be feeling for the majority the force of what’s going on in the ship. So gravity out in space artificially generated should feel a lot less bothersome thanon earth

    It seem to be very simple problem. The only point – no need to make circular form of station. Two space ships connected with some light construction between them rotating around their center of gravity. This connecting construction can be made as long as needed to reduce Coriolis force. For Zero-G experiments, central not rotating hub can be added to this scheme.

    How would it be different then being at sea?
    A sea legs comes with being at sea that has to be adapted to when coming off the ship

  18. HC Lau on August 26, 2021 at 10:25 pm

    Once we learn what actually drives Gravity, or what Gravity actually is, rather than just know how to calculate it, we would be able to create or shield ourselves from gravity. We understand Much EM waves, so are able to exploit it properly.

  19. AHungryGrizzly on August 26, 2021 at 10:27 pm

    I have to ask, you say there is limited benefits to having artificial gravity on a spacestation however hasn’t it only been discovered recently the effects of long term 0G on the human body? such as eye degeneration and heart problems basically ending any possibility of a 0G transit to Mars?

    1:33 NOPE! your video is silly, such a LARGE ship passing through the ring of a spinning station, WAAAAY to dangerous of a manoeuvre for such a large slow ship to attempt, it’s only blind luck their wasn’t a massive accident and loss of life.
    jk, i like your channel, just very very sleepy and silly =) good topic though.

  23. William Scoggin on August 26, 2021 at 10:31 pm

    Years ago I stumbled across the effect of things not moving with you when I was in my car. With the air vent to the left of the steering wheel pointed at me because it was a hot day. I started noticing off and on that is I turned the car to the right I didn’t feel the breeze hitting me it was going past me to the left and then as I straightened out my turn the vent was blowing back on my face again. I started informing my friends when they were in the car and got them to notice what was happening with their vent and they were amazed that they had never noticed that. Such a simple thing is such an eye opener.
    And your video was very well done, help me understand a couple of points I was barely grasping mentally as far as artificial gravity not being the same with the rotating Force. Thanks from Palestine Texas, home of NASA’s Columbia Scientific Balloon Facility.

  24. Isythos on August 26, 2021 at 10:32 pm

    Question is, how dense would we need to make an extra thick floor on spaceship need to be for it to generate a gravitational force akin to a planet, and would it collapse into a blackhole instantly.
    EDIT: Apaprently the Schwarzschild radius of the earth is 8.87 millimeters. This meaning if we could somehow fashion a material desnse enough to have a mass of the earth similar to earth that was bigger than a 8.87mm sphere we would have gravity aboard a ship. Say if all of the floor was made of such a material. Question is whether such a material is possible and whether a ship built around such a matterial would be structurally sound.

    Might be impossible to move. But might work for a space station?

    One advantage of artificial gravity is that if you spill something, it will go down. There are hygiene advantages to that. This would work with very low gravity like 1/6 G. High ceilings would be nice so people could jump, but that would be an extra expense. Maybe have a padded ceiling.

  28. SemiMono on August 26, 2021 at 10:40 pm

    The thing that always gets me in high-sci-fi with far-fetched ideas like ridiculous amounts of power being cheap and portable (light saber?), or gravity fields being something we can just generate, is they don’t explore the implications of such technology. What would people do with it? Take ME with gravity control being readily available. They can put it in something the size of a pistol, but you still walk and run places. Seems like locomotion would fundamentally change. Or with power, if you can fit the equivalent of a fusion reactor into a wrist-watch, and keep such a device cooled, why would you still wear a jacket? You’ve got your own personal space heater, AC, unlimited fuel for a propulsion system in zero G or in G, etc. etc. Everything would change.

  30. Mickey3finger on August 26, 2021 at 10:45 pm

    Gravity attracts, but centrifugal force holds you by inertia. I think that if you are in a huge rotating ship in zero G, and if you are not actually on the floor, then you would still be weightless, because you, the air molecules, and the ship are traveling at the same speed, there would be no forward motion on your body relative to the ship, therefore no inertia for the centrifugal force to counteract.

  33. lol2000x on August 26, 2021 at 10:51 pm

    Isn’t de problem with rotating space station that the radius has to be gigantic in order too have not too much "gravity" difference between your head and your feet iwch makes it infeasible?

    I recall reading somewhere that 0.2G was enough for a Mars mission. If this is the case then maybe building the sleeping/resting and exercise areas in the rotating part then the rest in non 0.2g areas like someone suggested.

    This makes me wonder. People who spend extended periods at sea can suffer from "land sickness" when they are on shore. I wonder if people who spend extended periods in rotating stations and ships would suffer from planet sickness when on the surface because their body is so use to the "ground" rotating.

  39. Don Allen on August 26, 2021 at 11:00 pm

    I stopped watching "The Expanse" when they "invented " ships with the exhaust coming out of the front just to be different. Obviously, they think their viewers are morons. And don’t go on about "tractor" drives, unless you are are moron too.

  40. mobilemarshall on August 26, 2021 at 11:01 pm

    Many of the problems are solved simply by scale.

  41. Tim Hyatt on August 26, 2021 at 11:02 pm

    arguably, clark got the timing right but it didn’t happen because he couldn’t predict the collapse of the space program. When 2001 was written, space exploration was in full swing and going to the moon was the ENTIRE focus of our space program… then, when we had gotten there, the congress started progressively reducing the funding more and more and more until it was a pale fraction of it’s original budget. Had we continued with space exploration as our focus, we would have likely had a 2001 style space station in orbit (several in fact, the L-5 system was a real plan, for a system of space stations around earth and the moon…..)

    But without the funding, and the lose of focus, space exploration took a back seat.. the Shuttle had been intended as the "delivery truck to orbit"….but with the loss of the Challenger, that program was doomed….it’s taken us two decades to even get close to being where we were with the Shuttle….

  44. michael dougherty on August 26, 2021 at 11:04 pm

    I wouldn’t dismiss the linear form, different propulsion systems are needed long term. Just because we can’t do something now doesn’t mean we won’t develop that ability later. If if doesn’t break the laws of physics, it is possible.

  45. RvnKnight on August 26, 2021 at 11:04 pm

    Stupid idea, but why not have counter-rotating rings and have the astronauts sleep and relax in the rings and take an elevator back to the center of the station for the day to day stuff?

    Sleeping in rotation created faux gravity is useful, but working in Micro Gravity is the most efficient.

  48. lee gibson on August 26, 2021 at 11:05 pm

    This is what I keep telling people that think we are going to Mars anytime soon. Mars has 1/3rd the gravity of Earth. We will need gravity on the 10 month trip there and while we are there. Its not just muscle mass and bone density. It effects our immune system as well. Check out the study done by NASA on twin brothers. One went to space for a long time and the other did not. The effect is startling. We will need a rotating ship or station that’s about a mile across to not be throwing up constantly. People need to take movies with a grain of salt. We are no where near a multiplanet species. I am not saying we should not try, far from it. Just be more realistic about it or people are going to die.

  49. MrTennessee24 on August 26, 2021 at 11:06 pm

    He is correct when he says that in artificial gravity created by rotation when created here on earth will still cause dizziness and motion sickness but that is because they are also still under the influence of Earths gravity, which is what causes that. Artificial gravity created in a weightless environment however is different. Without the gravitation influence of the Earth there would be no dizziness or motion sickness.

  50. 12crows1 on August 26, 2021 at 11:09 pm

    We will never explore the universe until we solve stable controllable gravitational fields. They are the key to everything!
