Is Earth Unique? Mario Livio and Jack Szostak on the Odds of Alien Life [Ep. 457]

Into the Impossible With Brian Keating

Does life exist beyond Earth, or is our planet genuinely unique? Can we recreate the origins of life in a lab? And what role does Mars play in the quest for cosmic life?

I had the extraordinary honor of discussing this with two outstanding scientists, Mario Livio and Jack Szostak. Mario and Jack just released their new book, Is Earth Exceptional?, which seeks to answer whether life is a freak accident or a chemical inevitability.

Tune in and join us for this mesmerizing exploration!

Mario Livio is an astrophysicist and author known for his work in cosmology and his popular science books. Livio has significantly contributed to our understanding of dark energy, black holes, and other cosmic phenomena.

Jack Szostak is a prominent biologist and Nobel Laureate known for his significant contributions to understanding life's fundamental processes. He was awarded the Nobel Prize in Physiology or Medicine in 2009, along with Elizabeth Blackburn and Carol Greider, for the discovery of how chromosomes are protected by telomeres and the enzyme telomerase.
