There are plenty of ways the Universe could be steady-state and still not have a white-hot sky. Suppose you have metric expansion as you do now, but new matter magically appears as a sparse, uniform cloud of particles throughout space to feed the creation of new stars and maintain the energy density we see today. Metric expansion guarantees that light is redshifted in proportion to distance, so the sky remains dark, even though the Universe is infinitely old and stable.<p>This model is wrong, obviously, but the reason has nothing to do with Olber&#x27;s paradox.
