Actually... you don't need to build the entire space station... You can built a wire-connected rooms structure that keeps it's shape by centrifugal force and some really small lifts to get into the center room, where people would socialize and feel no centrifugal gravity. That would reduce the cost and the amount of materials by A LOT.

NASA proposed a similar plan for it's original 1970s space station concept. However, the reason there are no serious plans to develop artificial gravity spacecraft of any kind is cost. NASA Human Space Flight (HSF) is teetering on the verge of ending because the very best engineers NASA has to offer cannot crack the cost barrier. The private sector has yet to demonstrate they can crack it as well. We only have HSF of astronauts on board ISS who are transported via Russian Soyuz craft. When NASA ISS participation ends, then what? There's lots of talk about going to Mars or back to the moon but no concrete plans that can be seen unfolding the way Apollo did. NASA's budget is currently at 1960 levels as a percentage of fed spending. We won't have any very ambitious projects on that budget. It's the main reasons SLS/Orion is on such a glacial test schedule.

Well, I've seen the youtube vids and heard the talks, and while people like Steven Greer and things like his disclosure project are fascinating to the extreme, my standpoint is that the only thing Iknow with absolute certainty is that I don't know anything. So when thinking 'seriously' about humans in space, I put all that aside as, say, inspiration for if I feel like writing a scifi novel. Seriously, then, I think there are some interesting developements going on in our efforts to reach space in a permanent way, efforts that build directly on top of what makes most of world's populace tick, and the social structures that made us so: Entertainment. I've been following this dutch-based initiativ, MarsOne, that wants to put a permanently settled colony on Mars, and they want to fund it by making it into a reality-TV show. And they are having succes with this business model, having got more than adequate funding for their preliminary work and testing, and also been promised additional funding as conclusions lead to new tests and further on the construction of various earthside fascilities that serves spacebound purposes. It's even worded like this because they want to keep their options open for any nano-material revolutions that might be happening sometime soon. In the background they also got a lot of scientific interest going for them - obviously - for also, sort of incidentally - being in the process of creating a platform for absolutely groundbreaking scientific research. And not only in space-relevant hard thechs; physics, mathematics, astrology, but also soft sciences as sociology and antropology. Even completely new branches that might have enourmous impact on the already established ones, like exo-allsortsofology. It's nuts how much momentum they got, and best of all is that it could not have gotten any weirder if Douglas Adams himself had come up with it.

You know the problem isn't about our capability of doing it. We could also build a high speed vacuumed train tunnel between US and EU. Then why don't we just do that? Because there is just no need at the moment while planes can do the same thing for cheaper. There is no need to build factories on the moon while we can still obtain elements from earth alot cheaper or there is no need for a gigantic space station while we can do all the science we need in a smaller one. We also don't need a space station to live on as long as there is nothing wrong with earths atmosphere or we don't run out of living space on earth. What you say would only be possible if our society advances to a point that manufacturing of food, transportation, telecommunication, policing, medical care, and so on is handled by machines. In that society people would no longer need to perform manual labour or even work to maintain their basic lifestyles. Work would be available in order to obtain a sense of accomplishment in life and only those driven by curiosity or a sense of duty would persue it. Only in a society like this can we do what you describe. In our current society which is ruled by money we just can't pursue greatness, everything is bound to profit.

I wrote a sci-fi story in which a small asteroid mining company simulated gravity by attaching opposing cables and pods to a heavy, spinning iron-ore asteroid. Since the asteroid was already spinning, no fuel was needed to spin it up to speed. The length of the cables was adjusted by the pods' electric winches to balance and calibrate the forces of the whole contraption. As I recall, it only produced the equivalent of one-tenth gravity so the cables didn't have to be super long and, therefore, didn't have to be composed of some fictional super-fiber. The pods had to be relatively lightweight, but parallel cables could be added if more pods (or weight) were added, two at a time of course. Obviously it could be done without the asteroid just by attaching the two pods together. But, by adding the asteroid in between, the cables can be much shorter. Too, the central mass creates a flywheel effect, which is more stable. Lastly, it was an asteroid mining operation so they kind'a wanted the asteroid. I ignored some potential problems, like the effect of solar wind, nearby gravitational forces, thermal outgassing of the asteroid, and the effect of movements of the occupants, any of which could slowly create an oscillation in the cables. Jumping up and down, for instance, would cause a tiny bouncing oscillation effect in the cables. It should cancel itself out in short order, but it would be troublesome if it were allowed to accumulate, but could be mitigated by well timed winch adjustments to the cables. So how did the pods attach themselves to the spinning asteroid, in the first place? Tangentially, of course, and simultaneously, with one on the opposite side as the other on a reciprocal heading.

You save some material that way, but you are losing some comfort and security. Now the only way to get to the other side of the station is through microgravity. And if your tether gets hit by an asteroid, there is way to have a backup that will take the weight, and your living space flies off into space. With a continuous ring, you can walk the entire circumference, and you can have multiple spokes supporting the structure. Your design also means that you're not maximizing the livable area. Every bit of material you add to make a larger ring also gives you greater surface area in the gravity section. So, if you want to accommodate a lot of people, you'll want to build one large, continuous ring anyway. You just want to work out how much material you can get to build the largest ring possible, for capacity and comfort of inhabitants.

Bolo and hourglass habitats address this. They have drawbacks to them that Torus don't. Then the Torus also has drawbacks that an O'Neil Cylinder does not. Really, scaling up makes it more stable and less dependent on fine tuning. If you have a larger and more complex biosphere inside of it, it can handle disruptions easier. With all of these habitats, wobbles can damage or destroy them. that is another thing that mass addresses. However, the odds of an asteroid striking a cable are probably the same as an asteroid destroying your house.

Abstract Use a laser to split a laser beam into two sets of photons, p1 and p2, that are connected by a special kind of hypothetical entanglement called a thread. A thread is a proxy for a small piece of spacetime. Use centrifuges to redshift p1 photons, blueshift p2 photons. The idea is to induce a time dilation across the thread. Since it’s a piece of spacetime, then it should acquire a length contraction as well, which is qualitatively like a curvature. The output of a laser beam would be a curvature beam. A curvature beam would act like a tractor beam.

common good ? Its not in my interest to send a bunch of people into space (or myself for that matter). It is however in my interest to send robots into space who mine the asteroids and/or planets, transform the resources into usable products and send those to earth for us to use. That way we can stop destroying and depleting the earth and make it a paradise with all the dirty manufacturing stuff happening in space. And then, in time, the robot factory complex in space can grow and ultimately prepare other planets for us to inhabit. I expect the space mining to start in this century, to mature in the next and 2 or 3 centuries down the line i suppose we can start inhabiting other planets. We dont need to make huge investments for non-sustainable projects now. If we start doing what is interesting for us now (space mining), soon there will be an infrastructure that allows us to colonize planets in a more sustainable way. Not by having many people pay for sending a few people, but by having self replicating robots basically do everything for free while we sit on our asses and just worry about keeping control of the AI instead of it controlling us.

The other large problem, not mentioned in the video, is that you need a fixed point, a source of leverage, around which to create that centrifugal spin. All of the spinning objects shown in the video are attached to something at the middle, allowing the outer structure to spin. In space, there would be no point of leverage around which to spin. Even if you put 1000 rockets around the perimeter, all facing and firing in the same direction, you wouldn't be able to control the oscillation in a single plane, which would be needed to keep it stable, and the structure would likely rip itself apart from the massive torsion created by the uncontrolled oscillation. If you could somehow overcome all of these issues, then centrifugal force could absolutely create the kind of artificial gravity in space that was proposed in the video. Unfortunately, I have yet to see or hear a good solution for the aformentioned problems, so it remains a largely moot point.

But centrifugal force *isn't* real.That is just an oversimplification that ignores the real forces that are in play that end up with the *perception* of centrifugal force. If you picture a space station that you have spun to create this artificial gravity environment, and you are standing in it. If it suddenly disappears, what happens? Do you fly directly away from the center of the space station, as centrifugal force would suggest would happen? No, you don't. You would fly along a vector that is tangential to the circle. Centripetal force is what holds you in the circle, and without a structure to exert that force, your inertia takes over. The reason the acceleration can be said to be in "g", is because the Earth exerts *acceleration* on you while you are on it, NOT force. Not bashing you or your video, just trying to put some knowledge out there.

Earth applies a centripetal force on you're body, there still is no such thing as an actual centrifugal force, what people generally perceive as a centrifugal force is really just an objects inertia resisting the centripetal acceleration. If there were 2 equal and opposite forces acting on an object during circular motion they would cancel out and the object would always fly in a straight line. Newtons 3rd law pair to the centripetal force from gravity on earth pulling you down isn't an equal centrifugal force pushing you up, the 3rd law pair is the gravitational force your body exerts on the earth.
@sequoiahughes85365 жыл бұрын
I'm sorry Aneutronic Fusion, but you are confused. Centripetal force and centrifugal force describe two different things, and you are not using the word correctly while the video most certainly is. Centripetal and centrifugal forces--while not true fundamental forces like the strong, weak, & electromagnetic--are concise and convenient ways to describe different phenomena. Centripetal force is inward-seeking, like gravity. Centrifugal force is outward-seeking, like what you experience inside the carnival ride Gravitron, or like the inside of a centrifuge. Arthur C. Clarke's (if i remember correctly) mnemonic to remember the difference: Centrifugal = centrifuge = pulled outward Centripetal = petals like a daisy flower = pulled inward Another example of centripetal force is the tension in a string if you were to secure string to a rock and then swing it around you; the rock doesn't fly away because of the strength of the string--its tension--which you may correctly call centripetal force. No phrase conveys the phenomenon displayed in the video more concisely or clearly than *centrifugal*, and really: you're not gonna have many opportunities to intelligently use the word centripetal in a sentence, unless it's to tell someone that they're using the word centripetal wrong.

So if we connect two Starships on a tether so the habitation decks are 684 meters apart and accelerate to one RPM, then we get Mars surface gravity. 684 m at one rev per 60 sec. Or 1000 m at one rev per 72.5 sec. Or 1789 m at one rev per 97 sec. To get Earth surface gravity, we could lengthen the cable to 1789 meters between decks and accelerate to 1 RPM. Or 1000 meters at 1.338 RPM Or 447.28 meters at 2 RPM. Or 111.82 meters at 4 RPM. Starship has several deck levels, so the slower RPM and longer tether is preferred to keep the gravity more similar between decks. Connecting the ships together at the tail ends may reduce tether stress because the heavy engines and partially filled tanks would be closer together. Certainly, the tethers would be shorter.

In science-fiction, artificial gravity is a generic correction expressed by the lack of budget. If the budget is lower, then the gravity will be closer to earth or "stronger". But with a decent budget, you can have more realistic sci-fi nowadays. Exemple : The Expanse, or Gravity. In "The Expanse" they treat gravity as it should be in space, different planets or asteroids have different gravity, changing everything to the liquid falling in your glass. Sometimes, the constant acceleration of ships will be sufficient to create momentary gravity which is lost when the ship is stopped, altered when it turns, or diminish when it slows. "Gravity" uses a gritty realism to depict a plausible accident in space in our time and around the earth. It very much illustrates it's namesake in an hour or so action sequence. "Sidonia no Kishi" also makes uses of space and gravity as a setting for many convincing mecha battles. (It also focus on the ridiculous range of fire and differing accelerations problems you may encounter in space.) So yeah, sci-fi is not dead, but if the 50s-70s era beleived in a magic artificial gravity, most serious writers now know it is a plot device for budget failings. It doesn't get Babylon 5 less brilliant on other points, but then... if you had to fail every sci-fi show for it's depiction of Gravity, you'd miss all the good ones. And again you have all the Star Wars and Firefly trying to explain artificial gravity as a feild phenomena with serious thinking. So maybe all isn't lost. Maybe someday... when a nuclear fusion generator will be safe, abordable and smaller than a car engine.

There were lots of issues with it. one being that the tanks would be toxic but there were plans to create protections using inflatable environments inside them. Another issue was to keep the tanks on orbit and to be able to move them around to be connected. Such a sad waste of the tanks only to be burned up upon reentry.

It came clear to me that we are dealing with two different definition of the word "force". There is only 4 forces, so the inertia of a mass accelerated (providing an external source of energy) or decelerating (wasting energy as heat, like in brakes or a car crash) is not part of these 4 forces. Debating on the word force often degenerate in a "deaf dialogue", which means two people will defend their point and think that the other is a total idiot. For the "word purist", it is absolutely forbidden to use "force" when describing inertia or Coriolis for example. On the other hand, those who try to understand what is really going on may think that his "adversary" deny the existence of inertia or Coriolis. If we can not only feel but objectively measure the motion of object in a car the accelerate or break abruptly, then don't tell me this is "fictious"... it is real. When we take the time to define the meaning of the words we use, it become clear that there is no real difference..

I know this video is old but you should do a video on artificial gravitiy in a rod. Essenstially, it'd be a spacecraft shaped as a long tube (which for the most part they are anyway). The tube would then be spun after reaching its desired orbit or perhaps after doing its last burn sending it to Mars. At the tips of the tube would be 1 G where the astronauts would sleep and exercise to maximize the benefits. This removes the need for a massive space station to avoid differential acceleration. Also, it is in general a much more resource efficient method to achieve artificial gravity.

1:05 I think centrifugal force is generated for a reason other than you said: our brain makes us think that the place we are in is stationary and we are the ones who move. For example, when you turn a car to the right, in reality the car is moving to the right, but our minds tell us that we are moving to the left (the relative moviment between us and the car); so, in its conception, there has to be a force to the left aplied in us, the centrifugal force. You said that it is because that, in a non-inertial reference frame of our body, everything but us is moving, but that's not the actual reason for the perseived force, if our brain really took that perspective, for it the body would stationary and the rest would be moving, in that case it would perseive no force in the body thus no centrifugal force. Actually, the brain takes the non-inertial reference of the place it is in, not of our body, so it ends up thinking the body is moving and the place is stationary. Which means that the place is inertial and the body has a force in it, the centrifugal one. That's is actually amazing, and shows how cool the nature of out minds can be.

You say the bottom line is that the guy is always going round in circles, but that's only in a non rotating reference frame. In a rotating reference frame he is standing still. There is no right answer for if he is going round in circles or not. It's same as with speed. If I'm on my bycicle doing 15 km/h, how fast am I going? There is no absolute right answer. Sure, I'm doing 15 km/h with respect to earth. But why would earth be the best / only reference.

Centrifugal force is correct here, because the illusion of gravity only arises when viewed from the rotating frame of reference, which incidentally, is the frame any subjects of said illusion of gravity will be finding themselves in.

@BearNDragon7 жыл бұрын
bcubed72, just because you feel a force equivalent to gravity doesn't make that force gravity. gravity by definition is a natural pull towards a center of mass. to do that artificially you would need to remove the mass but it would still be a pull towards a central point, not a push away. the difference isn't terribly relevant int this scenario since it functionally simulates gravity on the human body, however if you were talking about nuclear fusion then this "artificial gravity" could never be used to sustain fusion since it pushes away and doesn't concentrate mass at the center.

@samrichardson6308 жыл бұрын
Not quite. Artificial means "human-made" while simulation means "a false show." So while simulated gravity is artificial, it's not artificial gravity. Artificial gravity would be indistinguishable from natural gravity, whereas this sort of simulated gravity could be easily distinguished by anyone running in the wheel (they'd get noticeably heavier going one way and lighter going the other). edit: this is also why the author of the video is wrong to say that the force is centrifugal-- it's only centripetal, because a true centrifugal force would allow for a fair game of table tennis in the space wheel.

this is possible to build with a modular concept. Pretty much like oversized legos - the idea is to create multipurpose modules that can be sent into space, and in space, attached to each other, with interior tech added as required for each specific function. The ring would start with core modules installed, two tethers and 2 bigger sections at each end. Rotation would start then, to ensure gravity in the outer sections. Then more modules would be added to the outer sections, with more tethers as required, until a whole ring was formed.

Whoever says centrifugal gravity is not possible is an idiot and have clearly never taken a basic Physics course in school. When an objects spins, centripetal acceleration acts on the objects and the displacement of that acceleration is towards the center of the path the object travels. Go fast enough to have your acceleration 9.8 m/s^2 and boom, you have replicated "gravity"

The formula could be improved for ease of use. For example, let X= be the number of complete rotations and given that one rotation per minute is 2pi/60 we can substitute X.1047 for W. The new formula would be (X.1047) squared times the radius equals the gravity acceleration.

OK, I remember reading, ''if the main booster of the ol'shuttle was reduced to the size of a coke can, the walls would be thinner than a coke can !'' Why can we build that and not put together a simple wheel type space station ? Don't outfit every part when you fly it up there... get the 'V' built, THEN outfit it with what ever. If the bottom were solar panals (as well as the sides that would fold out) you coul orientate the wheel to always face the solar panals to the sun as it spun around, hence helpint to protect it's pasengers from the suns radiation. And, we don't need all that aluminum... that's what carbon fibers are for !

I have the impression rotational "gravity" will only work if the persons or objects are stationary, the centripetal force keeping them normal to the rotating surface. However as soon as the individual stands and attempts to walk, in one direction or the other, the effects of said gravity are not what one expects.

An inertial frame of reference (a reference that is not accelerating) is not "just an outside perspective". And you cannot create artificial gravity. You can accelerate and feel forces, but it's not artificial and it isn't gravity. Let's not get all loosey-goosey from the start.

The centrifugal force isn’t the force of reaction to the centripetal. It’s just that the dude spinning is in an non inertial system and he’s experiencing the centrifugal force,so that would be the correct answer for him. On the other hand someone outside the soace station would say that there is a centripetal force going on and that would be the correct answer for him
