Into The Unknown (starts at 7:57) What do we know about the universe, and how do we know we know it? Conversely, what do we know we don’t know, what don’t we know that we don’t know, and why not?

To help us unravel these age-old philosophical questions in the context of current science, our guest is Dr. Kelsey Johnson, who received her PhD in astrophysics from the University of Colorado.  Dr. Johnson is a Professor in the Department of Astronomy at the University of Virginia, and the former president of the American Astronomical Society. She is the founder of the Dark Skies, Bright Kids program, and wrote the children’s book Constellations for Kids. Her most recent book is Into The Unknown: The Quest to Understand the Mysteries of the Cosmos. In this episode, Dr. Johnson takes us into that unknown, and talks about what we know, what we might know, and what we might never know.
