The Universe in One Year

The Universe in One Year Every year on December 31 since I was in 7th grade I think of something I saw in an episode of Carl Sagan's Cosmos. I found this: Imagine that the history of the universe is compressed into one year—with the Big Bang occurring in the first seconds of New Year’s Day, and all our known history occurring in the final seconds before midnight on December 31. Using this scale of time, each month would equal a little over a billion years. Dinosaurs ruled the Earth for almost two hundred million years - from December 25 to December 30 on this time line. Most of our entire written history fits into the last 10 seconds of the year. It's something to think about while watching the ball drop tonight.
