Rockets work on the principle of Newton's third law of motion: for every action, there is an equal and opposite reaction. The action is the expulsion of hot gas, and the reaction is the rocket moving forward.

The ultimate fate of a star is primarily determined by its initial mass. Less massive stars like our Sun will eventually become white dwarfs, while stars significantly more massive can collapse into neutron stars or even black holes after a supernova.
