Michelson-Morley and Michelson-Gale experiments proved definitively that earth is motionless. Even Einstein himself, and every single one of the most credentialed Heliocentric physicists, cosmologists, and astronomers have repeatedly stated that neither orbital velocity, nor earth’s rotation have ever been proven. Einstein even went as far as to specifically state that Foucault Pendulums DID NOT PROVE ROTATION and that according to General Relativity NEITHER EARTH’S SUPPOSED ROTATION NOR ORBIT CAN BE PROVEN.
