But how can we be sure about timescales so far beyond the capacity for human intuition? Our discovery of what we now call deep time is very recent - as recent as our discovery of the true spatial vastness of our universe. And it came as scientists tried to measure the age of the Earth. What they found was as shocking and humbling as anything seen through the telescope.Hosted by Matt O'DowdWritten by Dan Falk and Matt O'DowdGraphics by Leonardo Scholzer, Yago Ballarini, and Pedro OsinskiDirected by: Andrew KornhaberExecutive Producers: Eric Brown and Andrew KornhaberEnd Credits Music by J.R.S.
