2. The Big Bang

About this unit

Big History will introduce you to many new ideas and claims. You won’t simply accept these claims as facts and move on. You’ll be encouraged to test them. You’ll learn how to evaluate information presented to you, and be encouraged to decide for yourself what to believe and what to investigate further. This is how our thinking advances. Today’s scientific view of the history of the Universe is based on the work of thousands of scientists and scholars over thousands of years. People built upon each other’s work. New technology and new observations have led to ever sharper theories about the Universe and its beginnings. As you study how these views have evolved, you’ll develop your own skills for testing the claims of others and making claims of your own.
