  • Many people are truly imaginative when it comes to thinking of alternatives to established cosmology models. One listener recently asked, “Could the expanding universe be caused by the emptiness on the outside sucking everything in its direction?” Hear countless possibilities offered by alternate universes on the nature of the cosmos.
  • It’s a half century since James Lovelock originated the Gaia Hypothesis – which says that our planet’s biosphere is a single intelligent entity that self-regulates conditions for the mutual benefit of all. Hear how physicists have been heading down this path for a long time and about the alternative: The universe was created from nothing.
