Pretty cool 8 minute video here... Theoretical physicist Michio Kaku talks about a bit about future civilization and extra-terrestrial life. Saying basically to 'find out' about ET life would take millions and millions of years for us to get to that point, or perhaps intelligent life is the rarest phenomena in the galaxy- at leas that's how I interpreted it. Pretty interesting if you have the 8 minutes to spare to watch it. http://www.youtube.com/watch?v=5wZYpkSmjUU&NR=1
