In this deep dive documentary, we explore the most profound gaps in Earth's history and human civilization. The Great Unconformity represents up to 1.2 billion years of missing geological record - literally erased from existence. The Bronze Age Collapse saw the simultaneous destruction of every major civilization in the Mediterranean around 1200 BCE, with writing systems disappearing and cities abandoned. The Younger Dryas brought sudden ice age conditions that changed humanity forever. And the Toba supervolcano eruption may have reduced our species to just a few thousand survivors.
