Gravity isn’t like a chair that you can just take out of the room, so it’s quite complicated. Gravity is the attractive force of a far larger object so (while on earth) when people do zero gravity things its when there is another force equal to gravity,like vertical wind tunnels (the wind pushes you up at the same speed gravity pulls you down) or the zero-gravity flights (the plane flies down at a specific angle,so you fall at the same rate as the plane!) it feels like there is no gravity-but it’s still there!
