Lesson 5 - Explaining and Evaluating Evidence for the Big Bang

What is Hubble's Law and how does it relate to the expansion of the universe?

• Hubble's Law states that galaxies are moving towards us, indicating a contracting universe.

• Hubble's Law states that galaxies are moving away from us, indicating an expanding universe.

• Hubble's Law states that galaxies are stationary, indicating a static universe.

• Hubble's Law states that galaxies are moving in random directions, indicating a chaotic universe.
