Paul Davies

looking into the "Big Questions" of existence

Paul Davies is a theoretical physicist.

Davies has worked for much of his career in astrophysics and cosmology, with emphasis on the origin and early stages of the universe, the quantum properties of black holes and the nature of time. He is interested in the nature and origin of life – including extraterrestrial life – beyond Earth, and in complex systems generally.

Astrobiological Implications of Interstellar Material in the Solar System

Our Solar System is not isolated. As it slowly orbits the galaxy, its astronomical environment changes and varying external factors can be influential. The history of our planet and its neighbors can be fully understood only in the context of the broader system.

The search for the origin of life

Mar 1999


My research spans from physics and cosmology to the origin of life, and the search for extraterrestrial life.

I'm most interested in the proverbial ‘big questions’ of existence—from what happened before the big bang, to whether or not we are alone in the universe.

These twin interests inevitably lead me into areas where physics and biology overlap. In recent years I have become involved in research on the origin of cancer and its deep evolutionary roots, a subject with important implications for therapy.
