Por NASA Podcast #Recomendado Tweet Gravity Assist: Is Artificial Intelligence the Future of Life? With Susan Schneider 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. In this episode of “Gravity Assist,” learn about what life might be like in the future and how science fiction has influenced thinking around this topic. Bonus: Jim Green’s theory about the movie “2001: A Space Odyssey.”

With Lindsay Hays When we search for life beyond Earth, we have to figure out what we could measure that would tell us that life was, or is, there. And the starting place for that search must be Earth itself, the only place where we know for sure that life has lived. Every rock tells a story, and so does each fatty acid called a lipid. Your cholesterol, which is part lipid and part protein, could last for billions of years, and contains the information that you are a mammal. Could we find lipids beyond Earth? NASA astrobiologist Lindsay Hays explores this and other topics in her research. She also discusses places interesting for the search for life in our solar system and beyond.
