The Big Bang Theory

1. What is the Big Bang theory?

• 1. B. A theory about the origins and evolution of the universe

• 1. C. A theory about the formation of galaxies

• 1. D. A theory about the expansion of black holes

3. What is the significance of CMBR in supporting the Big Bang theory?

• 3. A. It provides evidence of the early formation of galaxies

• 3. B. It supports the idea of a steady-state universe

• 3. C. It is leftover radiation from the early universe and matches the predictions of the Big Bang theory

• 3. D. It confirms the existence of dark matter in the universe

4. What does redshift refer to in the context of the Big Bang theory?

• 4. A. The shifting of light towards longer wavelengths

• 4. B. The shifting of light towards shorter wavelengths

• 4. C. The movement of galaxies towards each other
