What happens when light gets to the edge of space or universe, does it get reflected back. Assuming that light gets reflected back at the edge of universe. We are seeing the reflections of the same star galaxy, at different points of time, at different location. Since the reflected photons travel a greater distance than the photons of the real object, the reflected photons would be of lower frequency when compared to the light from the actual object. So if we eliminate all the reflections from actual direct light of stars (luminous objects), would the size and mass of the universe that we intepret as of now, be smaller than what we perceive.
