John Davis, are you saying you yourself has no idea how gravity works, or the astrophysicist, or scientists, or the human race in general?
So, you're not happy with the concept of the larger a mass is, the stronger its gravitational pull is? Einstein didn't prove that gravity is caused by the warping of space time around a mass?
I'm thinking you need to buy yourself a mouth guard and go and tell Buzz Aldrin what your thoughts are.....
