Can We Create Artificial Gravity? 

Ah yes but then how would we employ all our population? Lol whenever the job market is shrinking there's a war. Hell of a coincidence.

To do that, you'd have to change human nature.

All those trillions didn't get spent in iraq if that much was spent! Maybe one and a half of them did but the majority went to bush and his cronies of bilderburg skull and bones. Biggest money hoarders in the world!!!!

7 trillion isnt that much when its for nation security, its a shame that is where the focus is though

Azriel money not a problem if every person involved says they will do it for free? Say an end of the world scenario. Always laugh when money is involved in space exploration problems. It’s not like we have to buy all the equipment of some alien Walmart lol 😂

He did talk about the amount of steel that is needed

'No bucks, no Buck Rogers.'

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.

Agreed, it was a little annoying. Basically all he said boiled down to "it's super expensive", and nothing about HOW it could be done. His example of the station from Space Odyssey only talked about making it spin faster, not about what the right size would be. This video? Great idea, failed execution. =^x^=

Yes, this! The floors could have a slight cylindrical curve matching the circumference of spin. The connection would be several parallel pipe made into a rigid truss. If that is not important, then just walk up and down slight slopes. The rigid truss is replaced with "light weight" redundant tethers. I just finished calculating various distance between two tethered Starships vs angular velocity for Mars and Earth gravity.

¿What about that this would be the first stage of the project and you keep expanding it until you have the entire ring-wheel?

Slavko Bogdanic Exactly. You have a 1G living and working base and you just extend out from each end as you need more space.

Yeah, you are correct. As of 2017, the total global annual aluminium production stands at about 60 mil tonnes. Carrying this payload and building in space must be a greater problem as there arent enough resources and manpower to build that big a structure in space. Building ISS itself took around 12 years I suppose.

@Hernando Malinche Why would you have to cut pensions. The resources available in space dwarf those of Earth. The first corporations to exploit them would make their money back in no time. To do this only takes administrative effort... not cost. All upfront costs would be paid back and then ensuring pensions for generations.

Wait for it,... That's still a lot of recycled cans. (troll face)

@Hernando Malinche thats beside the point. Open it up to private enterprise and the private sector will absorb the cost. Tax it and cover ongoing costs such as policing and regulating it.

@Hernando Malinche It's very difficult to justify cutting pensions either ethically or legally, because ethically speaking pensions are earned and cutting them is cheating people out of what they were promised, and legally they constitute a form of contract so courts are going to have something to say about breaching that contract.

@@rc-pf1wq I'm more concerned about what happnes if you jump? Ever tied jumping on a bus or train? I sit like that where lanind is difficult or would you not notice?

@@rc-pf1wq Yup. The spin would definitely affect its trajectory. Its called the coriolis force and it is a real thing on earth itself. Snipers need to account for it when they are aiming at something sufficiently far off.

Maathiu Ra Yin You would have to maintain the 1 G acceleration to the half way point and then turn the space ship around and decelerate with the same 1 G deceleration all the way to you get there.. What engine and fuel could sustain a 1 G acceleration over a long journey ? Not sure any such engine and fuel exists..

cool concept! But you'd need one hell of a cable :D

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.

If they could only find a way to produce Graphene in larger quantities. This would be a big Step on the way to Step 1

Graphene isn't strong enough either, I will make a video about this eventually. I actually specialized in carbon fiber composites for my thesis. A subject I am really passionate about, but people overstate the strength of composite materials. I would say, with a fair bit of confidence, that we will never see a space elevator.

I say even if it seem impossible for such strong material to exist now, we should still chase after it. We will learn something new every attempt we try.

Real Engineering Huh? I thought that Graphene was the only material which could withstand the forces? Sad to hear that this isn't the case at all.

Apparently boron nitride nanotubes and diamond nanothreads are also candidate materials for building a space elevator (though I imagine we're nowhere close to being able to produce those in significant enough quantities to be used for that purpose).

You're right, there isn't. The Earth is flat and motionless.

It is going to be difficult to move that large ball of rock away from the Earth, and if we did, the Earth would tend to miss it what with the loss of tides, etc.

MrDeaz yeah and we would have been nuked by now

But I get what your saying that would be awesome

Unfortuately Trump has also said he wants money put into exploring the rest of the solar system rather than colonizing mars, which sucks because i think we need to go expand because im afraid of what humanity is doing/will do to this planet if all of this war continues. Also imagine what the mars colonies would be like, no war, very little conflict, only progress, and lots of resources, heaven in my view

I could imagine that war on Earth will end when we find another planet to attack. Considering back in the early days, it was tribes against tribes, then cities, then countries, now big military alliances vs countries.

MrDeaz Your right, we need an alien invasion or something similiar. Suddenly all of humanity would shit themselves and huddle together for survival

Yeah, the cost is not even that much. Heck, the Pentagon loses that much money all the time.

And that is pretending the best technology we have to get to space is spaceX and Rocketry, which honestly it isn't.

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.

The thing is just that we don't need a station like that. It would serve no purpose other than very expensive and dangerous living space and labs.

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.

Indeed! Ideally the cable would be a few kilometers long to make spinning slower than 1rpm. We could also use a dummy weight on the other end. Ot just very very long cable. Small dummy weight is probably the cheapest and lightest option

I could be wrong but I seem to remember something like this being done.... not with the intent of artificial gravity but at least tried....

how do you spin it without bending the cable or messing up your orbit

+William Herron I think you'd have to have two rockets on either end to fire at the same time to help keep the orbit stabilized...

Better yet, a super strong rod, so you wouldn't need to waste fuel on the rockets. Although a material that could provide such strength doesn't exist atm, but I could be wrong.

You and me, both. Consider that NASA's entire operating budget is less than was spent annually on just air conditioning of offices and officer's quarters in the war in Iraq. Look it up. The scale is unbelievable and eye-opening.

And ITER budget is less then people annually spend on IPhones. Let's stop wasting money on those silly things?

>one or maybe even more space stations like in 2001. Why? I mean why building

USAs military budget is the largest compared to anyone in the world. I dont know what they fuk they are doing with all that money.

EASYTIGER10 I agree. It doesn't even have to be semetrical. Put your people on one side, have a long cable, and put your supplies on the other. If one side is more massive, it will move in smaller circles, so both ends would have the same centripetal force.

Rapidly crossing into varying gravitational forces like that can have adverse effects on the equilibrium

That is what Zubrin et al proposed in their Mars Direct plan, albeit on a small scale, of course. The ship at one end of a long tether, and the spent upper stage of the booster at the other end, rotating around each other. Artificial gravity (at least a fraction of Earth's) for the way to Mars, so the astronauts get there healthy and ready to go.

This is where physics turns into mechanical engineering. The materials would have to be much stronger if the structure is unbalanced or unsymmetrical. A circle is just simply the most stable structure.

It’s never going to be built. There isn’t enough aluminum on earth to build it and space mining isn’t a thing because the cost of space mining outweighs the profits gained from it.

Exactly what I was thinking!

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.

Three masses works well, one in the center for zero-g and docking.

*twang* Goodbye Earth. Hello cold abyss.

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.

The main problem with a bolo setup is that it only takes one micrometeoroid impacting that tether to send the two spacecraft hurtling in opposite directions, spiraling out of control. A solid structure would be preferable for long term habitation, both for durability and ease of maintenance. A bolo has a single point of failure that is just too glaringly obvious.

+Irish Identity I agree a tube like structure would be nice so the People could go between the two units with out a space walk. Perhaps redundant tethers also for structural stability and reduced weight.

Have you read Seveneves by Neal Stephenson? Science fiction novel dealing with an apocalyptic event and the survival of humans by going into space.

+Irish Identity no but it sounds awesome I'm going to look it up.

A circle 2ould also be better for long-term travel because the whole point of simulating gravity is to allow the muscles to exercise. It would be much easier to have a torus,like in Seveneves, because of how easy it would be to walk

If you built it with radius somewhere between 75 000 - 85 000 km radius (I don’t now how to calculate certain number) , it would need to spin once a day, soo you can connect it with space elevators. Speed would be between 6 and 7 km/s

Se but that only works because you accelerate up to teh correct speed. What happens if you get stopped dead in a centrfugal spacestation? Do you just start ping ponging around? if theres no outside gravity pulling on you to hold you in position and you jump in a space station, while you would be carrie dforwards it would akin to jumping on a moving vehicle, landing would be difficult. And thus walking aorund should be difficult too. Even a smooth moving plate on teh end of a pole would feel slightly off.

The same thing that made you go down in the first place, inertia.

okay, so if I float in orbit and someone put a cenfrifuge around me ( with the same trajectory so there is no contact ) I would somehow be attracted to the sides of the centrifuge? ( if the jump negates the inertia )

No, if you somehow magically appeared inside it, you would float above it. That isn't going to happen though, you will either be inside it while it accelerates or you will climb down from the center of rotation. The structure will need to transfer inertia to you.

oh yea that is logical but it sounds to be a quite tricky system in practice if you would treat it like a normal space station. Love the video BTW. kudos

+Mathias Petersen. is this in a vacuum or air? it would make a difference

This is a variation on the Musk strategy to colonize Mars (as outlined by waitbutwhy): make a travel pass cheap enough that there are one million people willing to pay for a one-way trip.

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.

it's not in your interest to send a bunch of people into space? Then what the fuck is all bellow you wrote? Point is space travel. Traveling to another planets. Seeing new unseen shit.

#InThe Butt yeah you can it's called tape

K, stupid..

Thentai :(

It's called "Sci-Fi," or "Science Fiction" for a reason..

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.

+xunk16 apart from the rest of your rather good comment: "you can have more realistic sci-fi nowadays [like]... Gravity." Nice joke xD

It doesn't matter. The fact that you can't even tell the difference should tell you something about relativity of that kind of things :)

The only problem is centrifugal force doesn't work in high orbit.Centrifugal force requires at least some Gravity in order to work.

I don't know how you got that idea, but no, centrifugal force is a force separate from gravity. You do not need gravity for it to work.

What is wrong about his explanation?

@@michielm5120 He explained that changing perception (reframing the point of reference) changes the forces involved. That's simple not possible, and does not work. The forces and the causes of those forces do not change based on the frame of reference. Nothing is pushing you down, regardless of your perception. Instead, your momentum is being continually resisted and redirected by the "floor" of the rotational object. That's classic centripetal force.

@@jpcrafton69 there is no one absolutely right perception. Someone from out side would say it's momentum and a centripetal force but to the person inside the system the centeifugal force is entirely real. The perception of the person in the rotating reference frame isn't wrong or less right/accurate. Physics is just a model of the real world. The model for non rotating reference frames isn't better or more right than the model for rotating reference frames

Centrifugal force is absolutely fake. The reference frame doesn’t matter here, the bottom line is the guy is always spinning around in a circle meaning he always has an acceleration towards the center of the circle meaning that the centripetal force pulling in is NOT balanced out. Centrifugal force is an “inertial force” which essentially means it’s a phenomenon caused by a bodies desire to stay in motion and an unbalanced external force pushing against it. But and inertial force is not a force, it’s more like an illusion

@@CullenMorris97 I think everyone here knows what it is and that's it is a fictious force, but none the less, for the person in a rotating reference frame, it's real. 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.

to cancel out earths gravity. this artificial gravity is designed for space, so they need other stuff for it to work when there already is gravity

William Herron riiiiiight Thanks

he's hanging by wires on his side. Kinda like a hollywood ninja movie. You're looking down from above and the spinning drum is flat on the ground.

It's simulating weightlessness in a 2D and ignores the depth.

Cause its not real gravity, its simulated gravity by just duplicating centrifugal force - if he stops moving -he's screwed. Artificial gravity is just fantasy thinking, because they can't even explain what gravity is. It's funny how they refer to space as having microgravity now - what a joke.

Zubner's Mars Plan uses this method. There would be a crew compartment and a storage module connected by a long cable spinning around a center of mass.

pretty clever

Cables snap, and if the linking cable were to snap the two modules would be slung off into outer space in opposite directions making rescue impossible because the main ship which is traveling forward would not be able to change direction to retrieve the modules. Think of it like if you were traveling in a car and something you were holding out the window fell, the car would continue it's forward motion and the fallen item would be left behind. In a car you can slow down and back up and maybe find the item because gravity stopped it and it's laying on the ground somewhere. But in space the two modules would continue to travel away from you because there is no friction to slow them down.

I forgot to mention the properties of metal work differently in space then on Earth. The repeated heating and cooling of the metal in the cable would make it brittle... almost insuring eventual failure. Especially if it's under tension as both modules are pulling on it through centrifugal force. This is why you always see the wheel spokes structure used in these designs. Because if 1 section fails the rest can bare the load... the spokes also distribute load evenly around the entire circumference of the circle helping the whole thing to be much stronger then if you just had two modules at opposite ends

*twang* Goodbye Earth. Hello cold abyss.

That would not replace gravity. Your skeleton needs a force on the mass of your body like an inertial force.

@@wazzawizza4181 I don't know any less expensive alternative which can replace gravity. I am not an expert of the result for the human body, but it isn't the same and I think that the body would react differently.

Jarrett, at the surface of the Earth, the differential is small and we've evolved to handle it. On a small, rotating station, the differential would be significant and enough to cause problems described in the video. Fighter pilots for example have to tense the muscles in their lower body when making high speed turns to keep the blood from going to their feet and passing out.

It’s a matter of understanding the definitions of centrifugal and centripetal. Our schools have failed.

One thing is certain gravity is not the force working to create artificial gravity. Consider the attraction mass has does not require spinning, think on it

it is being put to good use.

Cbreezy yes, to kill peoples :D

No, to protect from killing people.

Cbreezy no its not

to protect a nation of wannabe soldiers that don't respect the law

👏N👏E👏P👏H👏E👏W👏

Maybe if you have a simple, quaint mind.

Seriously.............?😂

Stfu

Bobby Jones Jay Leno taught me that lol.

T Abel I saw that video as well. Jay Leno's Steam engine was awesome. I completely forgot about that until you mentioned it.

I'm slightly disappointed to know that although I guess my balls are relieved...

"Balls to the wall" is a term coined to describe Chuck Norris walking into a building smaller than an aircraft hanger

What does that term mean I don't really feel like looking it up because I might find something weird

Unfortunately, with one section spinning in the opposite from the other, the double wheel design would cause it to start spinning sideways in a circle around itself. This is how reaction wheels on satellites and the ISS work. They use three flywheels driven by electric motors in an X/Y/Z-axis configuration to get full control of spin or twist in any direction. Quite a clever idea, not to mention cheaper and more energy efficient then using chemical RCS thrusters. The way they did it in Space Odyssey 2001, with the whole station rotation in the same direction, is actually a better way, they just needed the station to be bigger to be able to match earth gravity. Good idea, though. =^x^=

I’ve been in one of those Except you just got strapped in and since there isn’t any outside frame of reference it just feels like superstrong sideways gravity

That's Balls Out!

Because you did not drill a hole in your cup

in a nutshell, yes.

Its ShonenLad

Newtons forces acting on said thing basically?

As you said: It's centripetal acceleration that creates the "gravity". So people who say that centrifugal gravity isn't possible probably just mean that there is no such thing as centrifugal gravity but centripetal gravity. I definitly agree that it's stupid for people to argue like that but it's right in a way

Lol just go to any county fair, the ride goes by many names, but in it you lay on the wall and it starts spinning fast and the walls start to move up and down and you can feel the force keeping you against the wall

It's not a force it is normal acceleration! But I understand the confusion.
