Answer 1

The three correct answers that provide evidence of universe expansion supporting the Big Bang theory are:

1. Galaxies are moving away from each other - This observation, known as the redshift of galaxies, indicates that the universe is expanding.

2. The temperature of the cosmic microwave background radiation varies widely from one part of the universe to another - This variation is evidence of the early hot and dense state of the universe, supporting the Big Bang theory.

3. The enormous amount of cosmic microwave background radiation has been detected - This radiation is a remnant from the early universe, providing strong evidence of the Big Bang theory and the evolution of the universe.

The options regarding the universe undergoing a cycle of contraction and expansion, the temperature of the universe decreasing, and the temperature of the universe increasing, are not correct in the context of current understanding of the expansion of the universe.
