Therefore, an observer always has the access to both his proper time, measured by his clocks, and the universal absolute time measured by the clocks at relative rest to cosmic matter! This universal time, the same time everywhere in the universe, is operationally equivalent to the temperature of the cosmic microwave background radiation in the expanding universe. In fact, theoretical cosmology always worked with such a universal time, akin to Bergson’s time, but never recognized that the physics done in this same and only universe has such a universal time.
