In order to move, you have to apply an equal force to something else, right? So how can rockets move in space where there are no particles?
In: Physics
In a few words: they are simply splitting in half
The solid part (what we call the rocket) goes one way, the gas part (what we call rocket plume) goes the other way. That’s why a rocket is almost entirely made of rocket fuel that burns almost explosively, because gas isn’t really heavy by itself, so you need a lot of it and you need to throw it really really fast.
