according to big bang theory, the universe started out with a very hot beginning, and has been cooling and expanding ever since. which two observations of cosmic microwave background radiation support big bang theory?\na. cosmic microwave background radiation redshifted and increased in mass over time.\nb. cosmic microwave background radiation exists in all areas of the observable universe.\nc. cosmic microwave background radiation contains all of the dark matter necessary to start the big bang.\nd. cosmic microwave background radiation stores the same amount of energy the big bang likely released.\ne. cosmic microwave background radiation has a relatively consistent temperature throughout the observable universe.

Answer

Brief Explanations:

The cosmic microwave - background (CMB) radiation is evidence for the Big Bang theory. It is nearly uniform across the observable universe and has a relatively consistent temperature. Option A is not a correct description of how it supports the theory. Option B is incorrect as CMB radiation doesn't increase in mass over time. Option D is wrong because CMB doesn't contain all the dark matter for the Big Bang. Option E is also incorrect as CMB doesn't store the same amount of energy as the Big Bang release. The existence of CMB in all areas of the observable universe (Option C) and its relatively consistent temperature throughout the observable universe (Option E) are key observations that support the Big Bang theory.

Answer:

C. Cosmic microwave background radiation exists in all areas of the observable universe, E. Cosmic microwave background radiation has a relatively consistent temperature throughout the observable universe.
