Well Jeff since it sounds like you were absent at class for quite some time while I was learning. And since your comments are beginning to make you look silly. And of course because you "obviously" know, please explain what gravity is....
Especially since we do not even have a completed theory "of" gravity let alone a complete model.. As the best known of the four fundamental forces "gravity" seems to be thought of as basic science and easily explainable by most people. It is not. Einstein's calculations seemed to lead to gravity being the "warping of space time", but we don't know what it is or the why of it. ALL work done with gravity calculations is like working with "Ohm's Law", which of course is no 'law", at all, is it Jeff? Or did you solve that all by your lonesome as well?
I don't come here to argue. I come here to learn.
Besides, without gravities effects my turntable wouldn't even exist! Would it? But maybe if I could modulate the gravitational pull at the center point of the music groove I could......................
