OK, Galileo.

I just dropped a book and a single sheet of paper from the same height. The book hit the ground first. Someone call the physics police! I broke the scientific law according to supramax!

In all seriousness, you need to understand that air resistance imparts a force on a falling object and that your "scientific fact" is only true of an object in a vacuum. Put a 1 lb weight on a small parachute. Put a 1 ton weight on the same parachute. Do you think that they'll fall at the same rate?
