Hi, I'm starting a new thread. Lets go back and re-look this whole thing about relativity. Is there a better way to formulate relativity. My thesis is that the non-linear time dilation around massive bodies causes the effect of "gravity", not the other way around. Non-linear time dilations causes non-linear distortion to a particle's shape, thereby causing the center of mass of a particle to move towards the "gravitational" source. The net effect is free fall in a "gravitational" field. If this is the case we can directly test of Lorentz's contraction. Direct observation of Lorentz's contraction has not been done. Anyone interested in this approach? If so I'll present a 6-particle scenario that suggest that the spacetime has an attribute, spacetime grid, that is distorted by relative motion, but spacetime itself is not necessarily distorted.
