As empty as space is, it does have some forces – some particles there and there, radiation from the stars, gravity of some planets. It could not spin forever , but it would come close to it, actually. Meanwhile a fidget spinner would spin much shorter, because of its internal friction in the bearing.
Can you stop rotating in space?
The axis of their spin cannot change , since that is set by their angular momentum, but the orientation of the body relative to the spin axis can be changed. There are only two ways he could do this. The first is if he has something he can spin within his suit — kind of like a personal CMG.
Can you stop yourself spinning in space?

Can you feel if you are spinning in space?
Astronauts feel weightless when both they and their spacecraft are accelerated only by gravity. To the astronauts, it feels just like there is no gravity. Humans don’t even really feel the gravitational force since it pulls on all parts of our body.
Will you get dizzy if you spin in space?
As astronauts come down from space, the blood rushes down toward their legs and away from their heads. This shift in blood makes some feel lightheaded and dizzy . Richard Cohen of the Harvard-MIT Division of Health Sciences and Technology says that on Earth gravity pulls blood toward the lower body.
How long would a top spin in space?
You could satisfy OP’s premise by spinning a top then teleporting it 500 miles straight up; this is about twice the altitude that the ISS is flying at and is definitely “space.” The top would only spin for a few minutes in that case, as it would quickly find itself falling through the atmosphere and burning up.
How long would a fidget spinner spin in space?
So lots of things are going against your nice fidget spinner, making it slow down in about 2 minutes . If you take it up to the ISS and I’m sure they’ll take one up to the ISS the next time they go up. Chris – International Space Station.
What happen if you spin too much?
Because if you spin too much you can be sick or throw up or poop your pants . Because your brain is going cuckoo. Movement sickness or hitting your head. Because it makes your brain spin around and around.
Is a rotating space station possible?
NASA has never attempted to build a rotating wheel space station , for several reasons. First, such a station would be very difficult to construct, given the limited lifting capability available to the United States and other spacefaring nations.
How fast do you have to spin to create gravity?
For example, to produce standard gravity, ɡ 0 = 9.8 m/s 2 with a rotating spacecraft period of 15 s, the radius of rotation would have to be 56 m (184 ft), while a period of 30 s would require it to be 224 m (735 ft).
Do astronauts faint during take off?
The lack of gravity astronauts encounter during spaceflight makes returning to the force of Earth’s gravity a little disorienting. And when they return to Earth, they faint . A new study published Friday in Circulation, the American Heart Association’s journal, has identified a way to avoid that.
Why don’t you get dizzy in space?
Your inner ears are telling your brain you’re moving, and to correct your vision, but you’re not actually moving. So like others said below, this would still happen in space, because the motion of the fluid is angular, and would be unaffected by gravity .
Do animals get dizzy from spinning?
Cats can get dizzy for similar reasons as a human, like spinning around too fast. However, they do tend to have more balance and refinement than many other animals. If you notice that your cat starts to stumble, look out for the symptoms typical of certain health conditions.
Why do fidget spinners spin so long?
Fidget spinners are essentially low-friction ball bearings. That’s it. When two objects press against one another, friction prevents them from sliding smoothly. ... But, thanks to the balls between their surfaces , the races can spin for far longer, subject only to rolling friction.
What happens if you spin a fidget spinner in space?
But in space, the centre part doesn’t stay still. “ Allowing the fidget spinner to float reduces the bearing friction by permitting the rate of the central ring and outer spinner to equalise, and the whole thing spins as a unit ,” NASA explains in the video description.
Does spinning damage your brain?
Concussion of the brain: A traumatic injury to the brain as a result of a violent blow, shaking, or spinning. A brain concussion can cause immediate and usually temporary impairment of brain function such as of thinking, vision, equilibrium and consciousness.
