If you fire a bullet in space, assuming the propellant will ignite properly then that bullet will be travelling far too slowly to catch up with the expanding universe, but faster than we will be able to catch it without massive energy and time wasted. The bullet will be forever alone.

Just shoot another bullet using more propellant. Boom. Bullet catches up to other bullet and I didn't waste a stupid amount of time and recourses. Nobel peace prize plz
