      Interesting!
      But it is fact or fiction?

        I confirm it’s all true.
        These are the foundations of modern physics.

      Propulsion moves things like spacecraft or jet planes forward by pushing something out of the back. Think of a balloon that you blow up and then release. The air rushing out of the back pushes the balloon forward. This happens because of a phenomenon described by Sir Issac Newton: “every action has an equal and opposite reaction.”

      As there is a friction equal to zero, in the space is enough a small push by a small engine to travel for a time almost infinite in space, without ever slowing down.
