What are two pieces of evidence that support the Big Bang Theory?
A
red shift of light and the different shapes of galaxies
B
planetary motion and cosmic background radiation
C
planetary motion and the different shapes of galaxies
D
red shift of light and cosmic background radiation
Explanation: 

Detailed explanation-1: -The pieces of evidence of the Big Bang theory include the following: redshifted galaxies and universe expansion . presence of the cosmic background radiation. percentage of light and heavy elements present in the universe.

Detailed explanation-2: -The Cosmic Microwave Background (CMB) is the cooled remnant of the first light that could ever travel freely throughout the Universe. This ‘fossil’ radiation, the furthest that any telescope can see, was released soon after the ‘Big Bang’. Scientists consider it as an echo or ‘shockwave’ of the Big Bang.

Detailed explanation-3: -Some pieces of evidence used to prove the big bang theory are moving galaxies, cosmic background, and the age of the universe.

Detailed explanation-4: -Blue wave lengths are shorter than average wavelengths of visible light. What Hubble observed is that the universe has an overall red shift in visible light. This means that the universe is expanding moving away from the observers. It is this observation of the red shift that gave rise to the theory of the Big Bang.

Detailed explanation-5: -Answer: The two key pieces of evidence that support the Big Bang theory are the cosmic background radiation and the observed helium content of the universe.
