Which two, observations of cosmic microwave background radiation support big bang theory?A.Cosmic microwave background radiation redshifted and increased in mass over time.B.Cosmic microwave background radiation exists in all areas of the observable universe.C.Cosmic microwave background radiation contains all of the dark matter necessary to start the Big Bang.D.Cosmic microwave background radiation stores the same amount of energy the Big Bang likely released.E.Cosmic microwave background radiation has a relatively consistent temperature throughout the observable universe.

Answer 1

The two observations of cosmic microwave background radiation that support the Big Bang theory are:

B. Cosmic microwave background radiation exists in all areas of the observable universe.
This observation indicates that the radiation is a remnant of the early universe and provides evidence that the universe was once in a hot, dense state.

E. Cosmic microwave background radiation has a relatively consistent temperature throughout the observable universe.
The uniformity of the temperature of the cosmic microwave background radiation supports the idea of an early, homogeneous state of the universe, which aligns with predictions from the Big Bang theory.

These points underline the evidence that the universe has expanded and cooled from an initial hot state, as proposed by the Big Bang theory.
