Description
The Earth is teeming with life, but the upper atmosphere to kilometers underground. There’s no question that our planet has life. But is our planet itself alive? This is a question posed back in the 1970s as the Gaia hypothesis, and it got its share of criticism. Some new ideas have been proposed to bring this hypothesis to the modern era as we search for exoplanets.
Bio: Fraser Cain is the publisher of Universe Today and Dr. Pamela Gay is a Senior Scientist at Planetary Science Institute and a Director of CosmoQuest. They team up to do Astronomy Cast, a weekly facts-based journey through the cosmos.
