This week astrophysicist Dr. Kelsey Johnson and I talk about how we know what we know, the Big Bang, black holes, and turtles all the way down, all of which can be found in her new book Into the Unknown: The Quest to Understand the Mysteries of the Cosmos. This is a mind blowing conversation with a brilliant and wonderful human.

About our guest:
Dr. Kelsey Johnson teaches students both inside and outside of the classroom, using astronomy as a gateway science to nurture curiosity and support science literacy. As a child, Johnson spent countless nights outside under the stars, where she developed a love for "big picture" questions about the nature of reality and the universe. Johnson's curiosity about the cosmos - and everything in it - has been the primary driver of her career, leading her to devote her life to learning, exploration, and teaching.

She is a professor at the University of Virginia and founding director of the award-winning Dark Skies Bright Kids program. She has won numerous awards for her research, teaching, and promotion of science literacy. Her TED talk on the importance of dark skies has more than 2 million views, and her writing has appeared in nationwide publications, including the New York Times, Scientific American, and Washington Post. Her children’s book Constellations for Kids in consistently in the top 10 children’s astronomy books. Johnson is the past-president of the Astronomical Society of the Pacific, and president-elect of the American Astronomical Society.

She earned her BA in physics from Carleton College, and her MS and PhD in astrophysics from the University of Colorado. She lives in rural Virginia with her family, including three cats and two very large dogs.
