Mysterious radio signals from space test Einstein's General Relativity theory
This illustration shows how two photons, one at a high frequency (nu_h) and another at a low frequency (nu_l), travel in curved space-time from their origin in a distant Fast Radio Burst (FRB) source until reaching the Earth. A lower-limit estimate of the gravitational pull that the photons experience along their way is given by the mass in the center of the Milky Way Galaxy.
