Main Question or Discussion Point
I just started reading A BRIEF HISTORY OF TIME and I am having a problem understanding Stephen Hawkings explanation of why all bodies fall at the same rate. If I weigh twice as much as someone else and we both jump off a cliff at the same time I would tend to think that I would fall faster because I have twice the mass. I pull on the Earth more than he does and it pulls on me more. I know that the rate at which things fall is constant in a vacuum I just don't understand why.
