John: The ball will fall to the ground. Shawn: How do you know, you did not even throw it yet? John: Even if I still haven't thrown the ball, I know! Do you think Shawn was correct for asking that question?

well if i were shawn i would not ask it because i know the law of gravity...i know that anything less dense will fall to ground because of the earth's gravitational pull...

Well, the ball could be filled with helium or something.. then it wouldn't fall.
