Distance Duality Test: The Evolution of Radio Sources Mimics a Nonexpanding Universe
Distance duality relation (DDR) marks a fundamental difference between expanding and nonexpanding universes, as an expanding metric causes angular diameter distance smaller than luminosity distance by an extra factor of (1 + z ). Here we report a test of this relation using two independent samples o...
