From the formation of the universe to the theory of matter to life on earth, Richard Morris delivers a clear and concise picture of what we know, how we know it, and what the limits to future knowledge might be. Morris begins by discussing various ideas about the ultimate destiny of the universe: whether it will continue expanding or eventually collapse. Next he addresses the search for a unified theory of matter that will encompass the four known forces in nature: gravity, electromagnetism, and the strong and weak nuclear forces. Finally, Morris looks at the origin of life. Once conditions were hospitable, life evolved on Earth almost immediately. But how? With wit and insight Morris takes the reader on a tour through some of the more profound aspects of contemporary science.
