Why knocking is so important.

There's a difference here Drich. My faith in what science says about gravity can be confirmed by rational research, testing, and inspection. What you are asking us to have faith in is the truth of words in a two thousand year old book which we can't verify. The two kinds of faith aren't in any way comparable. The rest is just window dressing.

(And unfortunately for you, anyone with a fair knowledge of physics could see that Chuck handed you your ass. Average acceleration of gravity at the earth's surface is independent of any other forces which might act upon and interfere with the pull of gravity at the earth's surface, such as air drag. That you don't understand this basic fact is your failing, not his.)
