It is a postulate of SR that the speed of light in an inertial frame is always c, no matter what inertial frame is in question. But clealry, as I've understood, the Earth is not an inertial system and our bodies cannot be considered to travel inertially. So my question is, what is the speed of light that hits our eyes in everyday life?
