Good stuff. Note above where I said what I'm not accounting for is gamma ray bursters. Not so. I have the firm grasp on what's real. Others mistake abstraction for reality. The theory corresponds to the facts. E=mc² is not wrong. The photon has inertial mass. It's the same as active gravitational mass. Neither are really mass. Like relativistic mass these are really measures of energy. They didn't make any mistake. You have. Now go and look up active gravitational mass.
