Suppose you are inside a very large empty box in deep space , floating ( i.e not touching the box from anywhere initially).The box is at complete rest. Now you push the box forward from inside. Now you would go backwards but the box will move forward to conserve momentum. However since you were inside the box your force is an internal force but the box would have moved forward. So doesnt this violate newtons 1st law as an internal force made a body move from state of rest?
