Chapter 20.3, Problem 1BE

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.

Einstein's theory is newer, and scientists alvways prefer newer theories. Newton's theory was never useful, so it had to be replaced by something. Einstein's gravity makes correct predictions in a few cases where Newton's…
