Why is fuel still needed in space?
If space consists on nothingness, why would a rocket need fuel to gain momentum? For example, if you were to hit a golf ball in space, it would keep going and going right? So besides a gravitational pull from the Earth that the rocket initially needs to escape from, what other reasons are there for the fuel used for acceleration? My main question is, if the fuel is needed, how does it create a push for the rocket to gain velocity or turn when there is nothing to push from (i.e. air)?
