Simple Physics

If you are in an atmosphere where you have zero gravity and a complete vacuum, you cannot propel yourself without using any means. Without friction you cannot trick physics into moving you forward by slowly moving your arms back then quickly thrusting them forward, like you can in an office chair. If you are surrounded by a frame, where your feet are pressed on one side, and you can push on the other, you cannot create motion by pushing forward on the frame and remain with the frame. This is because you have an equal force pressing against your progress. If you were as Superman and were able to creat motion without equal force, then you would be able to move the frame forward.
