Exploring the Big Bang Theory

What does the cosmic microwave background (CMB) tell us about the Big Bang theory?

• It shows black holes exist.

• It is leftover radiation from the early universe, supporting the Big Bang.

• It explains how fast the universe is expanding now.

• It disproves cosmic inflation.

What is the role of the Hubble constant in cosmology?

• It measures black hole density in the universe.

• It quantifies the universe's expansion rate.
