Fredo’s spaceship takes him to the very edge of known space. There, gravity has no effect at all. Fredo takes a baseball and tosses it into space. What will most likely happen to the ball?

With no gravity or other force acting on the ball, it will keep moving at a constant speed in the direction Fredo tossed it. This is inertia: an object in motion stays in motion unless a force changes its movement. So the ball will continue moving in a straight line.
