Why Have We Not Found Any Aliens? - with Keith Cooper

After six decades of examining signals from space, why have we yet to discover evidence of extra-terrestrial life?
Keith's book "The Contact Paradox: Challenging our Assumptions in the Search for Extraterrestrial Intelligence" is available now - https://geni.us/JFpy

For the past six decades a small cadre of researchers have been on a quest, as part of SETI, to search for extraterrestrial intelligence. So far, SETI has found no evidence of extraterrestrial life, but with more than a hundred billion stars in our Galaxy alone to search, the odds of quick success are stacked against us.

Keith Cooper explores how far SETI has come since its modest beginnings, where it's going and the assumptions that we make in our search for extraterrestrial life.
