Imagine you're on a spinning merry-go-round. When it stops suddenly, your body feels like it's still spinning, that’s how space sickness works. In space, the parts of our body that tell us we’re moving stop working properly because there’s no gravity to help them out. So astronauts get dizzy and feel sick, just like you might on a bumpy car ride.
Examples
- Astronauts floating around like they’re in a giant bubble, then suddenly feeling queasy.
- Floating food that moves independently of the person eating it, making everything feel even more confusing.
