Tag: Einstein General Relativity

Since the days of Einstein, physicists have the theory that the speed by which the light travels through a vacuum is constant. But two new studies proves that the space is not vacuum, so the speed of light isn’t constant. These studies was suggested by the physicists from Paris University by leading of Marcel Urban and the researchers Gerd Leuchs and Luis Sánchez-Soto from Max Planck Institute. The study of Urban, suggests that the space teems with virtual particles, which possess energy levels. But the study of Leuchs and Sánchez-Soto think that the electrical and magnetic fields of those particles can impact the light, during its traveling through them. This impaction will slow the speed of the light.
