Is intelligent life trying to communicate with us from space? Professor Paul Davies explores the potential and limits of research into the origin and evolution of life, and the search for life beyond Earth. Has ET maybe visited our planet ages ago and left us a message? At the Australian National University, Paul Davies discussed his latest book The Eerie Silence: Are We Alone in the Universe?

The acclaimed British-born theoretical physicist, cosmologist, and astrobiologist Paul Davies is the director of the Beyond Center for Fundamental Concepts in Science and co-director of the Cosmology Initiative, both at Arizona State University. He is also a member of the Search for Extraterrestrial Intelligence’s (SETI) post-detection committee. Among his numerous scientific distinctions, Davies is a recipient of the prestigious Templeton Prize for his work on science and religion. His writings include the bestsellers The Mind of God, About Time, How to Build a Time Machine, The Fifth Miracle, and The Goldilocks Enigma. In his provocative new book, Davies challenges existing ideas of what form an alien intelligence might take, how it might try to communicate with us, and how we should respond if we ever do make contact.

A new warning from astrophysicist and global science guru Stephen Hawking: Do not talk to aliens.
The brilliant Hawking is wheel-chair bound and speaks through a computer. But he’s thinking about the cosmos.
With billions of galaxies, trillions of stars, the numbers tell him there’s life out there. The smartest forms could make it here. But we should not want that, says Hawking. Too much danger.
Other scientists disagree. We’ll hear that debate, and talk to the man who heads Earth’s greeting committee for aliens.
Are human beings the only example of intelligent life in the universe?
Dr. Jill Tarter, director for the Center for SETI Research, says it’s scientifically valid to ask if the same processes of physics and chemistry that resulted in human life and civilization might have occurred elsewhere in the universe.
In this short podcast presentation, Dr. Tarter talks about the role that the Allen Telescope Array is playing in the effort to identify signals engineered by non-human life if it exists somewhere in the cosmos.
"Life on earth is made out of stardust. Life somewhere else is going to probably be made out of stardust too."
