    Question Is it possible to use mass movement inside a spacecraft to give acceleration using only onboard power?

    Sorry but I don't agree that the center of mass of the system will never move relative to and external observer. If you have a mass internally in a craft in zero gravity environment any movement of this mass internally will cause a craft to experience equal force in the opposite direction, it...

    Question Is it possible to use mass movement inside a spacecraft to give acceleration using only onboard power?

    Consider a squash ball, when it hits the wall of the court the rubber compresses and the air inside also compresses causing the balls temperature to rise. This temperature rise is energy taken from the balls kinetic energy, causing the ball the hit the wall with less force. Proof: A ball of...
