No, I dont believe in gravity, it's a made up THEORY to explain why somebody in Australia doesnt get flung off the spinning ball, which rotates faster than an airplane propeller. While we speed around the sun at 67000 miles an hour. The sun itself supposedly moving at 670000 miles an hour and our universe at over a million miles an hour. It's fucking insane man. Think about what they are saying here.
Weight is weight. It has nothing to do with this LIE called gravity. I'll refer you to density it covers it just fine on a flat plane.
