Big History studies the history of everything, offering a way of making sense of our world and our role within it.
When very large stars die, they create temperatures so high that protons begin to fuse in all sorts of exotic combinations, to form all the elements of the periodic table. If, like me, you're wearing a gold ring, it was forged in a supernova explosion.
If, in schools, we keep teaching that history is divided into American history and Chinese history and Russian history and Australian history, we're teaching kids that they are divided into tribes. And we're failing to teach them that we also, as human beings, share problems that we need to work together with.
If historians don't tell stories at the scales of creation myths, someone else will.
We inhabit an obscure planet, in an obscure galaxy, around an obscure sun, but on the other hand, modern human society represents one of the most complex things we know.
Humans are remarkable: the first species in almost four billion years of life on earth that dominates the biosphere. This gives us the power, in principle, to build societies in which everyone flourishes. But it also creates great dangers because it is not clear that we really understand how to use our potentially devastating powers.
All religions, all indigenous traditions, all origin stories provide a large map of where you are.
I had this feeling that, somehow, we ought to be teaching not just the history of particular nations or particular regions, but the history of humanity.
In literature classes, you don't learn about genes; in physics classes you don't learn about human evolution. So you get a fragmented view of the world. That makes it hard to find meaning in education.
Every kid goes to school full of questions about meaning. You know, 'What's my place in the universe? What does it mean to be a human being? What are human beings?' Existing courses cannot help you answer those questions. They can't even help you ask them.
Our goal is to see Big History become a normal part of high school curricula. I'd love to see it being taught in lots of languages. A global course.
I have this fantasy that in future negotiations over climate change - instead of going into that room and saying, 'I'm defending Chinese interests,' or 'I'm defending Australian interests' - there will also be an identity inside of each of the negotiators thinking, 'I'm also defending human interests.'
Gravity is more powerful where there's more stuff.
Living organisms are created by chemistry. We are huge packages of chemicals.
I believe human beings mark a threshold in the development of the planet, of course, but it is only part of the picture. What Big History can do is show us the nature of our complexity and fragility and the dangers that face us, but it can also show us our power, with collective learning.
Modern scientific knowledge appeared piecemeal. Historians wrote about human history; physicists tackled the material world; and biologists studied the world of living organisms. But there were few links between these disciplines, as researchers focused on getting the details right.
Learning to domesticate the horse was a sort of energy revolution.
I think what I was after was a unifying story that could bring everything together, that could give me a sense of the whole of history.
We, as extremely complex creatures, desperately need to know this story of how the universe creates complexity and why complexity means vulnerability and fragility.
Unfortunately, historians have become so absorbed in detailed research that they have tended to neglect the job of building larger-scale maps of the past.
