Let's face facts. A tree makes a noise if it falls in the woods. No one being there to hear it does not mean it did not make a sound. Why try to contravene physical science and the reality of solids with philosophic ethical theorems? Two objects of great mass and density colliding with one another will always produce a sound except when in a vacuum. As for the glass of water, if the glass was empty and water was poured halfway in, it's half full. If it was full and half the water was poured out, it's half empty.
