Hi
As you may know according to third law of Newton every action has a reaction.But my problem is that as we may know there is the need of friction for moving that you lean on something that you become able to move But as I have heard NASA has developed some gas-powered rocket maneuvering devices to allow astronauts to move freely in space without being tethered to the spacecraft (works according to third law of Newton)
But my question is without any friction and without any gas rocket and without anything that you stick to it,is it possible to move in space like by moving our bodies by ourselves ?
I mean is it possible to move without something that you stick to it or lean on it or without throwing anything from yourself ?
For example you just push your back with your hands then you move ?
Is it possible ?
Thank you very much for your answers
Have a nice day
