Contemplating the infinite is a time-tested way to shrink the present down to size. But if you think about it for very long, infinity can really mess with your mind. There’s something fundamentally paradoxical about it, and beautiful.

Deep Time is a series all about the natural ecologies of time from To The Best Of Our Knowledge and the Center for Humans and Nature. We'll explore life beyond the clock, develop habits of "timefulness" and learn how to live with greater awareness of the many types of time in our lives.
