You are basically correct. Gravity is the attraction between two masses center of mass (every part pulls but it all evenly distributes to being the center of mass). But how does the propulsion cannon strengthen this force pull to overcome the force of the planet's gravity directionally, applying itself to only one object? And how does it do so without becoming a black hole and consuming everything?
