Space travel
I can not fully get my head around how direction correctional thrust on a spaceship works as to my mind there is nothing to push against, but they must work or we wouldn't be able to accurately travel outside the Earth's atmosphere.
Not suggesting that we send a Fokker Friendship to the moon, but as a matter of interest, would propeller propulsion work just as well in outer space?

Thrusters work the same way, more or less, they just don't use rocks. What they use is compressed air or the gasses from combustion. Ummm ... if you blow up a balloon and let go, the air inside is forced out and the balloon goes shooting off. It's the same principle with spaceships.

"For every action there is an equal and opposite reaction" Forces work in pairs, no exceptions. When the rocket fires in the vacuum of space the gas molecules push against the nozzle and the nozzle pushes against the gas molecules. From the perspective of the rocket, it experiences a thrust force and, consequently, an acceleration in the direction of the thrust.
