Book Club Edition: The Giant Leap: Why Space is the Next Frontier in the Evolution of Life

from Planetary Radio: Space Exploration, Astronomy and Science · host The Planetary Society

Join us for an awe-inspiring conversation with astrobiologist and astronomer Caleb Scharf as he eloquently makes the case for "dispersal," the nearly inevitable advance of life and humanity across our solar neighborhood.  From the book: "The idea of Dispersal is one where the sheer scale and scope of life’s future extension into the solar system profoundly changes things: not because of some new (and unlikely) cultural enlightenment from within but because of what the enormous expanse of space will do to dilute and change our species and all others.” Adam Frank says of the book, “If we can make it through the many crises of the next century, then the Solar System and the stars beyond await us. In The Giant Leap, Caleb Scharf demonstrates how becoming a true space-faring species is more than just humanity’s future.” Discover more at: https://www.planetary.org/planetary-radio/book-club-caleb-scharfSee omnystudio.com/listener for privacy information.
