A billion years in the blink of an eye NOV 08 2011
When I was a kid, one of my favorite things on one of my favorite shows (3-2-1 Contact) was Al Jarnow's Cosmic Clock, a short video animation showing a billion years of time passing in fewer than two minutes. There's so much science in this little video.
This is one of those things I thought I'd just never see again. YouTube is truly a global treasure.
