Textbook Question
Chapter 22, Problem 18EAP
Decide whether the statement makes sense (or is clearly true) or does not make sense (or is clearly false). Explain clearly; not all of these have definitive answers,, so your explanation is more important than your chosen answer.
18. Observed characteristics of the cosmic microwave back-ground can be explained by assuming that it comes from individual stars and galaxies.

- The law of conservation of energy states that energy can be converted from one form to another but cannot be created or destroyed. Therefore, the amount of energy in the universe is constant. In your initial post to the discussion, respond to the following prompts: What do you think would happen if energy were not conserved? Think of (and share) two scenarios in which our lives would be drastically altered if this law of conservation was not in place. At least one of your scenarios should be at the molecular level. Would the implications be positive? Negative? Explain.arrow_forward1. Why big bang theory the most accepted theory on the origin of the universe? 2.
