What Is Life? #2: If We Find Alien Life, Will We Even Know It?

“What Is Life?” is an eight-episode podcast series recorded in front of a live audience. (Subscribe to the podcast at iTunes, via RSS, etc.) In this episode, I spoke to astrobiologist Sara Imari Walker.

Sara Imari Walker is a physicist and astrobiologist at Arizona State University. She studies life as a physical phenomenon, in order to develop new ways to search for it elsewhere in the universe. We shouldn’t assume that aliens will introduce themselves to us, so we need a way to recognize life no matter what form it takes.

Walker’s TEDx talk about a “universal theory of life.”
