‘A Universe From Nothing’ by Lawrence Krauss, AAI 2009 (by richarddawkinsdotnet)
Lawrence Krauss gives a talk on our current picture of the universe, how it will end, and how it could have come from nothing. Krauss is the author of many bestselling books on Physics and Cosmology, including “The Physics of Star Trek.”
Life probably doesn’t exist on one of the most famous exoplanets, the gas giant Kepler-16b, which like Star Wars’ Tatooine orbits two stars. But a potential moon orbiting this planet might be a good place to search for ET.
Kepler-16b is a Saturn-sized planet 200 light-years away that orbits a pair of stars with about two-thirds and one-fifth the mass of the sun, respectively. Yet with no solid surface to stand on, the planet seems unlikely to have any creatures on it watching the spectacular view of a double sunset.
