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."
