About

Big History is a unique course that looks at the history of the entire Universe, stretching 13.8 billion years into the past and all the way into the future. You’ll travel to the earliest stars, discover new chemical elements, investigate the Earth’s fiery origins, explore how life on Earth evolved, and journey through human history to see what the future may hold.

Unit 1: What is Big History? - What’s so big about Big History? It explores all 13.8 billion years of the Universe’s history. But it’s also about you, and the tools you’ll need to examine this history—like scale switching and claim testing.
Unit 2: History of the Universe and Earth - Why are we talking about outer space in your history class? Well, we all live on Earth, one planet in our Solar System that makes up a tiny part of our Universe. How can we know anything if we don’t start with the big picture?
Unit 3: Life - Living organisms have evolved into billions of different species since life first emerged over 3 billion years ago. While the complexity of life has increased over time, many species are extinct, which tells us life on Earth is also fragile.
Unit 4: Early Humans - We had to start somewhere. Discover the superpower that helped our earliest ancestors thrive like no other species: collective learning.
Unit 5: Agriculture & Complex Societies 10,000 BCE/12,000 BP–1500 CE - Just about everything we eat today started out on a farm. So, it’s easy to think that farming has always existed, but it hasn’t—humans invented it. As agriculture spread across the world, complex societies usually followed.
Unit 6: The Modern Age - Around 500 years ago, people lived in four distinct world zones. Our only sources of energy were the Sun and human and animal power. Understatement alert: A lot has changed since then!
Unit 7: The Future - Big History is an unfinished story. How do you think complexity will increase in the future? What do you think the next threshold of increasing complexity will be?

What is Big History? Big History is an academic discipline that examines history from the Big Bang to the present day, connecting the cosmos, Earth, life, and humanity into a single, unified narrative. It uses a multidisciplinary approach that integrates evidence from science and the humanities to understand cause-and-effect relationships across vast scales of time and space. The goal is to provide a holistic perspective and show humanity's place within the grand story of the universe. Most of it is history heavy with a few aspects from other fields.
