Did the great thinkers actually prove something? Or just write a bunch of brilliant equations to describe what is in an abstraction of symbols (math)? There is still great mystery in why. Why would two masses attract each other? No equation addresses facts of physical design, of why it's the way it is. So to me, even the science proofs didn't hit the mark. The equations didn't tell me why my pencil drops to the floor. Well, one could say it's because the mass of the earth is large and attracts other masses to it - but that's no real answer. Why would a mass attract another mass? So what did they prove anyway?
