Sara Imari Walker on Making Sense of Life, the Universe, and Ourselves
On Ep. 136 of Time Sensitive—produced in partnership with with the Aspen Art Museum and recorded in Aspen, Colorado, during the inaugural AIR festival—the physicist and astrobiologist Sara Imari Walker, author of the mind-expanding book “Life as No One Knows It,” discusses time’s essential role in the “assembly theory” physics framework she’s spearheading alongside chemist Lee Cronin, how her childhood growing up in an antiques-filled Connecticut home shaped her fascination with the material world, and why understanding life’s origins on Earth—and exploring alien life beyond our planet—is crucial to understanding ourselves.

As the physicist and astrobiologist Sara Imari Walker—the author of the mind-expanding book Life as No One Knows It: The Physics of Life’s Emergence—sees it, every single thing on Earth can be traced to life’s beginnings. Walker studies the origins of life on this planet—one of science’s greatest unsolved puzzles—and, beyond that, whether alien life exists on other planets. As part of her research, she’s advancing a physics known as “assembly theory,” a new way of thinking and talking about life’s origins and, in turn, time. She displays that rare gift for demystifying deeply layered concepts—and for reminding us of how profound it is to be alive, in this moment, in the first place.
On this special episode—produced in partnership with the Aspen Art Museum and recorded in Aspen, Colorado, during the inaugural AIR festival earlier this month—Walker makes a compelling case for why understanding life’s origins is crucial to understanding ourselves.
