Outer Space

How does a rocket ship propel itself in outer space?
If outer space is a vacuum, what does the rocket ship push itself against?
I like to think of it this way: Picture yourself standing on a four-wheeled cart, holding a bowling ball. You swing the bowling ball and throw it off the back of the cart as far as you can toss it. What happens to the cart? It will move forward – not a huge distance, but it will nonetheless move. If you have multiple bowling balls and continue to throw them off the back, the cart will gradually accelerate forward.
The bowling ball does not push against anything. In fact, the same demonstration could be done on the Moon, where there is no air for anything to push against. The cart moves forward because the bowling ball moves aft, and the momentum of the system as a whole is conserved.
A rocket engine throws a lot of tiny bowling balls out of its exhaust in the form of hot gas molecules. They aren’t very heavy, but there’s a whole lot of them, and they are moving really fast. They don’t need air – or anything else – to push against. In a sense, what they are pushing against is the rocket itself. They go out one way, and the rocket goes the other way. That’s what Newton said during the Plague years in England. That’s how long ago he said it.
