In a zero gravity enviroment, if a person is spinning, would they still get dizzy?

Answer 1

Equilibrioception is a fancy name for our sense of balance. If that is disturbed, dizziness is the result. The vestibular system in our inner ear uses the motion of fluid to detect our motion and acceleration. The brain combines input from this system with input from our visual system to establish equilibrium. That's why closing your eyes affects dizziness, and why watching the horizon reduces our tendency toward motion sickness.

When the rocket engines on a spacecraft shut off, the astronaut is suddenly weightless, and experiences the sensation of free fall. As he becomes accustomed to weightlessness, the vestibular system and visual system go back to their normal function of detecting balance. At that time, spinning would have the same effect on dizziness as it does in a gravity environment.

Answer 2

Good question! I think that they would (eyes open) because dizziness not only has to do with a sence of gravity but that your eyes have visual patterns that would contribute to the dizziness, but if your eyes were closed you would be less likely to get dizzy. I think.

Answer 3

maybe because some of the dizziness comes from the changing view, not from gravity

Answer 4

You tend to lose equlibrium the momment gravity on the fluid in your inner ear is reduced. Withoutout outside reference you wouldn't even know you were spinning

Answer 5

yes
