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, noted by Edwin Hubble, supports the idea of an expanding universe.

2. An enormous amount of weak cosmic background radiation has been detected in the universe. - This cosmic microwave background radiation is a remnant from the early universe and is consistent with predictions of the Big Bang Theory.

3. The temperature of Cosmic Microwave Background radiation varies widely from one part of the universe to another. - The uniformity and slight variations in the temperature of the cosmic microwave background support the idea of a hot, dense early universe as proposed by the Big Bang Theory.

The other options provided do not align with the evidence supporting the Big Bang Theory.
