Rethinking what counts as life

Sara Imari Walker, a physicist and astrobiologist, takes up a question that spans several fields: how to define life in a way that can also help explain its origins. The book connects that challenge to two practical pursuits—creating life in laboratories and searching for it beyond Earth. Walker argues for a new framework grounded in physics, culminating in a proposed theory for identifying and classifying life that is not limited to organisms on our planet. Along the way, the inquiry also turns to how scientists might frame questions when established definitions leave key possibilities unresolved. The result is a science-focused exploration of life as both a biological subject and a problem in physics.

Good fit for readers who enjoy

  • Readers interested in the origin of life and how scientists define it.
  • Those curious about astrobiology and the search for life beyond Earth.
  • Readers interested in connections between physics, biology, and laboratory efforts to create life.

Book overview

An intriguing new scientific theory that explains what life is and how it emerges.

What is life? This is among the most difficult open problems in science, right up there with the nature of consciousness and the existence of matter. All the definitions we have fall short. None help us understand how life originates or the full range of possibilities for what life on other planets might look like.

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 here on Earth and missions searching for life on other planets.

Walker proposes a new paradigm for understanding what physics encompasses and what we recognize as life. She invites us into a world of maverick scientists working without a map, seeking not just answers but better ways to formulate the biggest questions we have about the universe. The book culminates with the bold proposal of a new theory for identifying and classifying life, one that applies not just to biological life on Earth but to any instance of life in the universe. Rigorous, accessible, and vital, Life as No One Knows It celebrates the mystery of life and the explanatory power of physics.
