9. Zero Gravity Exists in Space
If not for gravity on Earth, we would all be floating around and it wouldn’t have been pleasant at all. So, gravity plays a very crucial role in space too because if it wasn’t for gravity, then the Moon would probably not even orbit the Earth the way it does.
Astronauts in space experience something called microgravity which does not have anything to do with the full force of gravity itself. Astronauts keep falling or wobbling sideways when their feet touch the ground (probably because of the weight of the suit) and that’s why they appear weightless.
