which statement best describes why the steady state theory cannot be explain the radiation

Answer 1

The steady state theory cannot explain the cosmic microwave background radiation (CMB) because it posits that the universe is eternal and unchanging on a large scale, with a constant creation of matter to maintain a uniform density as the universe expands. However, the CMB is a relic radiation that is uniform and isotropic, providing strong evidence for a hot, dense origin of the universe, as suggested by the Big Bang theory. The existence of the CMB strongly contradicts the steady state theory's assumption of a constant state without a specific beginning or a hot initial phase.
