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.

What's Eating the Universe?

and Other Cosmic Questions

In the constellation of Eridanus lurks a cosmic mystery. It appears as if something has taken a huge bite out of the universe, leaving a super-void. What is the culprit? A supermassive black hole? Another, bigger universe?


Davies is the author of over twenty books

including The Goldilocks Enigma,
How to Build a Time Machine,
The Mind of God, and many more!

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.

Space summary. For those who have seen the Earth from space, and for the hundreds and perhaps thousands more who will, the experience most certainly changes your perspective. The things that we share in our world are far more valuable than those which divide us.
