32 - "has anyone even figured out what gravity is? Einstein did. It's the curvature of spacetime. "

I guess he didn't tell anybody else. I'm smart, but no Einstein. What does what you said mean?

Anything with mass deforms the local space/time. In effect, we aren't stuck to the planet because of some kind of graviton. We are in fact slidding down a slope created by the gravity of the center of the earth.

Or some such BS.

Now ask him where the highest point of gravity would be. You'd think that it would be in the opposite direction of gravitational pull, ie; away from the earth, starting at the center of the earth. So theoreticly, you'd weigh a lot more standing two inches from the earths core even though there isn't enough mass between you and the core to make a difference.

However, if there is a graviton type particle/wave/wavelet, the focus of said particle would originate at the focal point ie; the center. The effect would propagate like all other observed forms of radiation with the effect thinning out over distance from origin.

Podkletnov and others are working on this as we speak.

Actually, Einstein published his theory of Gravitation. That's what his "General Theory of Relativity" is about.

Surely you've heard of the Theory of Relativity? There are entire libraries full of books on the subject.

It means that, in the real world, the shortest distance between two points isn't quite a straight line. In fact, it can be far from straight. Do you see the long, curvy things in this picture? Those are distant galaxies. Their images are distorted because the light from them always travels along what is locally the straightest path available; globally that means it curves around heavy objects (in this case, an intervening cluster of galaxies).
