If astrobiologists find life beyond Earth in the solar system, it will most likely be in the form of tiny organisms called microbes – nothing that would talk to us. But the galaxy is a big place; the universe even bigger. Somewhere out there, life may have evolved to become as smart, or even much smarter, than us. And the next step in that ladder may be “post-biological,” argues Susan Schneider, the Baruch S. Blumberg NASA/Library of Congress Chair in Astrobiology, Exploration, and Scientific Innovation. Advanced life may be entirely based on microchips and silicon, using the tools of artificial intelligence instead of brains. Listen to the full episode of “Gravity Assist” at nasa.gov/gravityassist.
