source site - John Hodgman's brief digression | Video on TED.com

Humorist John Hodgman rambles through a new story about aliens, physics, time, space and the way all of these somehow contribute to a sweet, perfect memory of falling in love.

John Hodgman ("I am a PC") gives his humourous take on whether we are really alone... aliens are not real. are they?? For all the seriousness that is in this world, this is a bit of a light relief.
