An Analysis on the Sign of Gravity of Antimatter

Abstract

Basing on the energy conservation, an analysis method on the gravity of antimatter is proposed by investigating the change of potential energy during high energy photon transfers to electron and positron in earth gravity field. Potential energy equations are deducted and proved that the force between matter and antimatter is attractive, and then the force between antimatter and antimatter is proved to be attractive too. So the gravity is attractive without considering matter or antimatter.
