One of the most powerful questions humans ask about the cosmos is: Are we alone? While the science behind this inquiry is fascinating, it doesn’t exist in a vacuum. It is a reflection of our values, our fears, and most importantly, our enduring sense of hope. In The Possibility of Life, acclaimed science journalist Jaime Green traces the history of our understanding, from the days of Galileo and Copernicus to our contemporary quest for exoplanets. Along the way, she interweaves insights from science fiction writers who construct worlds that in turn inspire scientists.

For centuries, scientists believed that living matter possessed a special quality—a spirit or essence—that differentiated it from nonliving matter.

Elixir tells the story of two young chemists who were not convinced, and how their work rewrote the boundary between life and nonlife.

Not only can we not currently explain the origin of the universe, it is questionable we will ever be able to explain it.
