Is Artificial Gravity Really Achievable? | Answers With Joe
Переглядів 1,810,261
День томуRotating habitats and artificial gravity are a staple of science fiction movies and TV shows, but the realities of space travel means that someday we'll have to get serious about artificial gravity to keep our astronauts and space travelers healthy. The question is, what's the best way to do that, and is it even possible with today's technology?

Well, consider that it's one of the most critical systems on a ship, along with inertial dampening and probably more critical than life support and you'll see why it rarely fails. There are several episodes of ST where gravity fails temporarily or a dead ship has no gravity requiring the crew to use "gravity" boots. Generally though you ignore it unless you need it as a plot device. I think it's more amusing that the vast majority of planets they visit have a gravitational force similar to earth.

We must fix this to stop being wasteful. I demand all houses to be 7 foot ceilings unless you are over 7 foot! Same height, but instead of two floors, and an attic? Seven floors! That would be a crazy house. If I were filthy rich I would build it then rent it out for super cheap. Break even basically! Then if it succeeds I would buy a ton of highly sought after houses, and build these monstrosities as three people homes. Call it the rat house.

By far the most frustrating thing about Gravity is how incredibly weak it is: Results from gravitational experiments we attempt in labs are ridiculously difficult to measure, and the only other option is looking up into space and hoping something happens that tests whatever it is we're studying; It's practically impossible to include gravity in any Quantum theories since it's effects don't even register at that scale; And even if we somehow figured out a perfect theory of Gravity that works seamlessly with the Standard Model and we discovered some way of controlling it, we would still only be able to generate tiny effects unless we were willing to make planet sized machines.

Your comment is ironic given what he talks about. I don't get how someone can run a science based channel yet completely ignore how everything they are explaining is clearly fine tuned and designed and pretend naturalism can produce it while flat out knowing there is no mechanism or logic that can. Mindless unguided process can't magically code information based life. There is no physical process or natural phenomenon that can create such communicative information. It's an immaterial concept to start with information. Rationality does not come from irrationality, the burden of proof is on those who say it does the naturalist. Natural selection is variation allowed within the genome. It's not a mechanism for evolution, it can't create anything. Turning genes on and off and swapping them isn't creating the genes to start with. No new information is being created. Entropy and information theory all point towards information decaying over time not the reverse. The statistical probability and logistics alone make evolutionary theory patently absurd. Whole thing is ridiculous to even entertain. It's all predicated on a mechanism that does not exist and logically can not exist.

Artificial gravity produced by rotation would certainly be different. I think people would be able to adapt fairly well at least in the short term.

None of us passengers could walk without holding on to something. Yet in the dining car the waitress was fully adapted she walked easily carrying trays of food. Then unbelievably poured coffee without spilling any. Although artificial gravity would be different . I doubt it would be as difficult as the random movements of that train.

You have made a mistake: If you flip your direction when using Orion drive you are not flying into your nuclear explosions. You can get some "wind" of your previous (before you flipped) explosions, but they should dissipate very well in a day or two. So you can completely avoid contamination from the flip. Because there is no stationary atmosphere in space (or at least: practically), firing your Orion drive opposite of the direction of your velocity does not result in flying into nuclear explosions at all. Things are quite a bit different if you are travelling at relativistic speeds.
@johnborden9208 4 роки тому
Exactly! Whether you're speeding up or slowing down, the ship would always be moving away from the explosions. (Or the explosions always moving away from the ship, if we want to look at it that way.)

There would be virtually no discernable difference when throwing a ball or turning your head because the effects on your body are relatively the same when compared to the speed of the core since it's 4 miles wide.

2001: A Space Odyssey was such a masterpiece and Kubrick's SFX team did an amazing job of helping to make it fully believable that rotation was so plainly the way to create artificial gravity. There was a flaw, though... the moon. Everyone moved about the Clavius base like there was 1G gravity. Anyway, the one thing that made the most sense was suspended animation. Wake the crew up for short periods of doing work, then put them back in hibernation. Of course, assuming it's a perfect kind of hibernation where no bone or muscle mass is lost...

When you listed the issues with "weightlessness" I think you missed one of the biggest problems: Reproduction. While no space agency has done rigorous experimentation on it, small scale tests have failed to get a successful incubation of any vertebrate. Some invertebrates have been hatched, but Mice and Frogs fail to develop embryos, and it seems very likely humans simply wouldn't be able to get pregnant without gravity; which kinda puts a kibosh on long term colonization of space without being able to replicate gravity.
@michaelnewton1754 4 роки тому
Interesting... I wonder why, and how much gravity would be needed. I always figured the tethered ships in formation would be the way to go. You could extend the tether enough that the rotations could be slow, and the difference between pull at head and feet would be minimal. Then maybe have some sort of 'climber' unit attached to the tether, to transport people and items between the ships.
@pl8827 4 роки тому
@@michaelnewton1754 My guess is that there are many points in orientation and migration of cells during embryo development that uses gravity as a guide. I'd wager that it doesn't take much gravity to get embryo development of vertebrates, but micro gravity (which is pretty much none) just won't work. Like I said this hasn't been thoroughly tested, but NASA has failed to get fertilized frog eggs to develop in micro gravity and mice fail to reproduce and get pregnant; that's all we have to go on at this time. Spiders, ants and most plants are just fine though, if it is an issue it only seems to effect vertebrates.

Lying down while sleeping nearly eliminates negative coriolis effects meaning a much smaller radius on the order of a few tens of meters, if that, would be sufficient to provide intermittent exposure, which would be better than none at all.

@hdufort 3 роки тому
One of the most interesting concepts that was explored recently in science fiction is the concept of a ring ship, where the WHOLE SHIP is rotating. Including the engine block. I'm talking about the Endurance in Interstellar. In all the previous movies and in the literature in general, we imagine a ship with a static (non-rotating) center core with engines, and then a rotating ring attached to it. There are major issues with these designs. The rotating ring needs to have a rotating airlock with the center core, which is a nightmare of engineering. And you have a rotating thing with mechanical parts and lubricants. So The Endurance's design makes much more sense. Make the whole ship rotate. Any ship with multiple rocket engines can be easily controlled by computers. Without the assistance of computers, it would be hell to pilot. But it's true for most designs anyway.
@tsamoka6496 2 роки тому
That is a fantastic idea. The only problem would be the faster you accelerate forwards, the more the "gravity" of the ship moves towards the engines. Imagine standing on a 45 degree angle relative to both the floor and the wall! I'm sure there could be some way of dealing with this, but it certainly would be a crazy experience. =^x^=

There have been quite a few experiments on ring stations, and much head scratching. The current thinking is that human beings would adapt to rotational gravity fairly quickly, even at the scale of 100 meters. There is no excuse for not having a rotating station in place already. The experiments and next step knowledge we would have could be astoundingly valuable, and the deadly effects of microgravity would be eliminated.

@firebird690 2 роки тому
Firstly the whole inner ear thing only applies if the axis of rotation is not perpendicular to your net experienced downward force. This applies to all experiments done on earth with gravity also present, making down not in line with the radius of rotation. This would not be an issue in space where your plane of balance is orthogonal to the axis of centrifugal force (from your rotating reference frame), meaning there isn’t a difference in angular momentum when turning your head side to side (although dipping your head may still present some minor discomfort, so don’t do that). second that Coriolis effect on a 4 mile (6.4 km) radius would be relatively minor as it only effects movement between different positions along the radius of rotation, so long as you throw and catch at the same height (more or less) and don’t make an arc to makes up a significant fraction of the radius (who’s throwing balls several km in the air?) you would not observe it. Remember it is the difference is speed that gives rise to the Coriolis effect, 1 m height represents less than 0.02% of the radius and in turn less than 0.02% change in linear velocity (v = omega x r).
@grlcowan 2 роки тому
It would require a very high ceiling for the "land to the side of you" below to be true: "a four-mile diameter, which would require 28 rotations per hour to target one gee [actually 31.6 revs per hour] ... when you throw the ball up in the air closer to the axis it picks up on that horizontal momentum which is a fancy way of saying you throw the ball straight up it will still curve and land to the side of you." If the ceiling is 3.5 m and the ball rises 1.5 m from the point where it left your hand, it will have moved 12.2 cm spinward by the time it gets back down to your hand.
