The temperature of Cosmic Microwave Background radiation varies widely from
one part of the universe to another
An enormous amount of weak cosmic background radiation has been detected in
the universe

The temperature of the universe is decreasing

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. The temperature of Cosmic Microwave Background radiation varies widely from one part of the universe to another.
3. Galaxies are moving away from each other.

These findings support the idea that the universe is expanding, which aligns with the predictions of the Big Bang Theory.
