Review Doppler, Shift, Birth of Universe

Why do scientists accept the Big Bang theory?

• It is a belief based on faith and religion.

• They trust other scientists.

• It is a money-making tool for scientists.

• Three pieces of evidence support the theory.

How does Cosmic (Microwave) Background Radiation support the big bang theory?

• It is a part of the theory that has never been explained.

• It is energy left behind from the Big Bang expansion/explosion in the form of radiation.

• It is radiation in space that was pushed to the outer edge of the universe during the Big Bang.

• It is visible light from the Big Bang that has traveled to the edge of the Universe.
