    Episode 195: TIme's Second Arrow
    Jan 28 2026
    Guest: Dr. Bob Hazen Mike is joined by his Carnegie Science colleague Dr. Bob Hazen. Together, they have written a new popular science book titled "Time's Second Arrow: Evolution, Order, and a New Law of Nature," which launches on February 10, 2026. This book describes how the marvelously complex constituents of our universe came to be. Evolution, they boldly propose, is a universal phenomenon—not only in biology, but in the entire atomic, chemical, mineral, and physical universe. Showing how a natural process of selection for increasing function has shaped the universe since its inception, they explore how a new law of nature could possibly help us identify life on other planets and—perhaps—even understand the purpose and meaning of life on Earth in a new way.
