Gravity may not exist any more than matter.

One of my greatest failures, is my inability to communicate the basic concepts about the nature of reality without loosing people who are less educated or more prone to mystical beliefs. Gravity is not a 'force', it is an apparent curvature in space-time, and according to this string-theorist may be an illusion, or a marriage. The concept is that, similar to temperature, the appearance of gravitational effects may come from the averaging of subatomic effects of the uncertainty-principal at the macroscopic level. This is a fundamental shift from the description of a phenomenon to an understanding of how or why it exists. This doesn't reject our traditional understanding or science, it simply deepens our knowledge about the nature of reality and energy. Similar to how we now know that matter is just patterns of energy and force fields in essentially empty space.
