Chapter 18- The Big Picture

Chapter 18 basically discussed a variety of aspects concerning light waves and space. I really enjoyed reading about the supernova research and how it developed a new system for scientists to see how fast the universe was expanding and slowing down. They discovered that the universe is constantly accelerating, which led to the "dark energy" field of physics. It is said that this discovery will lead to better research on the universe for years to come, and I think that's pretty important.
