Answer 1

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

1) Galaxies are moving away from each other.
2) The temperature of Cosmic Microwave Background radiation varies widely from one part of the universe to another.
3) An enormous amount of weak cosmic background radiation has been detected in the universe.

Answer 2

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

1. The temperature of Cosmic Microwave Background radiation varies widely from one part of the universe to another.
2. An enormous amount of weak cosmic background radiation has been detected in the universe.
3. Galaxies are moving away from each other.

Answer 3

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

1. The temperature of Cosmic Microwave Background radiation varies widely from one part of the universe to another. This observation supports the idea that the universe was once in a highly compressed and hot state, which then expanded and cooled over time.

2. An enormous amount of weak cosmic background radiation has been detected in the universe. This is known as the Cosmic Microwave Background (CMB) radiation, which is the afterglow of the Big Bang. Its discovery in 1965 by Arno Penzias and Robert Wilson was a significant piece of evidence for the Big Bang Theory.

3. Galaxies are moving away from each other. The observation of galaxies moving away from one another supports the idea that the universe is expanding. This was first discovered by Edwin Hubble in the 1920s and is now known as Hubble's Law.

To summarize, the evidence for universe expansion and the Big Bang Theory includes the variable temperature of Cosmic Microwave Background radiation, the detection of an enormous amount of weak cosmic background radiation, and the observation of galaxies moving away from each other.
