The three correct answers are:
1. Galaxies are moving away from one another. This observed phenomenon, known as the Hubble expansion, provides evidence for the expansion of the universe.
2. The temperature is decreasing. The observation that the temperature of the universe is gradually cooling down over time is consistent with the idea that it was once in a highly energetic and hot state during the Big Bang.
3. An enormous amount of weak cosmic background radiation has been detected in the universe. The discovery of the Cosmic Microwave Background (CMB) radiation, which is a remnant from the early stages of the universe, provides further evidence for the Big Bang theory.
which provides evidence of the universe expansion that supports the big bang theory? select three correct answers

the temperature is increasing
the temperature is decreasing
galaxies are moving away from one another
the temp of CMB radiation varies widely from one part of the universe to the other
