Answer 1

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

1. An enormous amount of weak cosmic background radiation has been detected in the universe.
2. Galaxies are moving away from each other.
3. The temperature of the universe is decreasing.

These elements collectively support the notion of a universe that has been expanding since the Big Bang, as evidenced by the cosmic microwave background radiation, redshift of galaxies, and the cooling of the universe over time.
