Charting the Architecture of the Universe & Human Life | Dr. Brian Keating

Andrew Huberman

Jan 20, 2025

Episode description

In this episode, my guest is Dr. Brian Keating, Ph.D., a cosmologist and professor of physics at the University of California, San Diego. We discuss the origins of the universe and how humans have used light and optics to understand where and how life on Earth emerged.

We explore how early humans charted the stars, sun, moon, and other celestial events to measure time and track seasons, as well as how stargazing continues to connect us to a shared ancient experience. Additionally, we examine the scientific process, the practical and ethical challenges of pursuing groundbreaking discoveries, and the emotional toll of striving for recognition in one’s profession.

Finally, we discuss whether astrology has any scientific validity and consider the possibility of life beyond Earth.
