A Cosmic Voyage Through Deep Time (with Ross Andersen and Grant Slater)
Humanity has a deep time problem. Our internal clock simply cannot compute on a time scale that takes into account the rise and fall of civilizations, star systems, and superintelligences. Unable to fathom consequences beyond our chronology, we make decisions and take actions that could snuff out our species in a blinding flash of light that would barely merit mention on the cosmic timeline.
Ross Andersen writes for The Atlantic about the sublime and scary implications of deep time. In this episode, he speaks with Futurology producer Grant Slater about how our view of time itself dictates what feels urgent now. From our definition of consciousness to our search for life in the cosmos, a wider frame of reference could dictate a new organizing principle for life on our planet and beyond.
