Life as No One Knows It

In 'Life as No One Knows It,' physicist and astrobiologist Sara Imari Walker argues that solving the origin of life requires radical new thinking and an experimentally testable theory for what life is.

This is an urgent issue for efforts to make life from scratch in laboratories and missions searching for life on other planets.

Walker proposes a new paradigm for understanding what physics encompasses and what we recognize as life, culminating in a bold proposal for a new theory for identifying and classifying life that applies to any instance of life in the universe.

The book celebrates the mystery of life and the explanatory power of physics.
