Question

8. You have studied the spectra of four sample galaxies and found that three of the four demonstrate red shift. Astronomer Edwin Hubble discovered that only a very few nearby galaxies are moving toward us, demonstrating blue shift. More distant galaxies are all moving away from us, demonstrating red shift as in this example. What does the red shift indicate? * 1 point The universe is diverging and expanding, which supports the big bang theory. The universe is converging and shrinking, which contradicts the big bang theory.

Answer 1

The red shift indicates that the universe is diverging and expanding, which supports the Big Bang theory. As galaxies move away from us, their light shifts towards the red end of the spectrum, indicating that they are receding. This observation is a key piece of evidence for the expanding universe model.
