- Q13Which of the following does not support the Big Bang Theory?Universe has a faint glow due to left over radiationStars and galaxies are moving toward Earth in all directionsHelium and hydrogen are the most abundant elements in the universe, because they were the first to form from sub atomic particlesStars and galaxies are red shifted45s

- Q15Which of the following descriptions correctly summarize the evidence that supports the Big Bang Theory? I. The universe started as a small point and is continuously expanding, which is evident due to red shift. II. Hubbles Law states that the universe is shrinking at a constant rate, which is evident by viewing galaxies moving toward Earth. III. Cosmic microwave background radiation gives evidence that there was a large release of energy early in the histroy of the universe, which left radiation throughout.I and III and IIIII and IIII only45s
