How did we get from the Big Bang to the age of artificial intelligence? What can the entire 13.8-billion-year history of the universe teach us about humanity’s future—from AI breakthroughs to space colonization?
David Christian, renowned historian and creator of Big History, joins host John Murphy on this episode of Ignition Sequence to unravel the grand narrative of existence—from the Big Bang to the present day. In this thought-provoking conversation, Christian explores how a Russian historian ended up teaching the story of everything, why understanding 13.8 billion years of complexity matters, and what the past reveals about our technological creativity, climate challenges, and potential for global collaboration.
We dive into the revolutionary Big History framework, the fragility of complex systems, and how humanity’s shared stories shape our unique power as a species. Could the next century see us colonizing other planets or modifying our own bodies? And will we harness AI and global unity to avoid catastrophe—or repeat the mistakes of history?
Christian’s insights blend science, history, and optimism, offering a mind-expanding lens on where we’ve been and where we’re going.
