ELI5: Why are astronaut's movements in space seemingly slow motion when there's no air/water resistance to slow them down?
gpt
There are a few reasons. Their suits are pressurized. The joints of these suits want to fully extend due to this pressure. This makes it difficult to move and do things, and reduces precision substantially. Not only this, but the suits are quite heavy, and have inertia to slow movements. Lastly, the astronauts do not have anything to stand on. Fast movements will make their bodies start to rotate and further reduce the precision of their motions.
