Ep 47: Are we alone?

A ToKCast Special: Brett talks about what he's learned over the years from various academics about the question of alien life. Although I don't mention it, I draw my inspiration from an academic paper I wrote years ago as part of my Masters degree in Astronomy - it can be found here: The Rare Earth That might be a bit more sober, hard-going and not exactly entertaining. I hope this video is fun. I don't read - I simply talk. It's a somewhat different style for ToKCast.
