You're floating in a zero-g vacuum, holding a bowling ball. You push the bowling ball away from you as hard as you can. If you were correct, the bowling ball would move away from you, but your position in space would remain unchanged. You're clearly wrong and dumb.
Quoting: Frumpelstiltskin Again, fluid movement due to pressure differential is not the same mechanism as throwing a ball. false...they both involv1er accelerating mass, and the resulting reaction....every action has an equal and opposite reaction...same thing applies to rocket engines accelerating hot gasses out of the engines, propelling the craft in the opposite vector...
