Big history is a new way of looking at the history of the universe. It looks at the story of the universe from the very beginning. It tries to connect different parts of history together and finds patterns in how things have changed. For example, big history looks at how different species evolved over time, how human history has been shaped by science and technology, and how cultures from different parts of the world have interacted with each other. Big history helps us better understand how we got to where we are today and why things are the way they are.
