You're wrong. Rocket propellant pushes against the rocket. The rocket pushes against the propellant.
Newton's third law of motion.
In space, there’s nothing to push against. Correct me if I’m wrong.
But the space craft, its not that hard
They apparently were hoping to push against magnetism or magnetic lines of force.................
True there is nothing to push against in space. But “pushing against air’ is how JET engines work. Rocket engines in space work by using the equal and opposite reaction to the expelling of matter (mass from the rocket exhaust) from the rocket engine. Just like if you were in space, and had a sack of rocks. By throwiing them down past your feet, one after another, you would propel your body up, faster with each rock thrown.
