The History of Our Cosmos in a Year

Was watching Carl Sagan’s ‘Cosmos’, and in the first episode, he proposed an interesting analogy:

… The cosmic calendar charts out the entire history of our universe in a single year. If the Big Bang occurred on January 01, 00:00:00 am, it was not until May when our galaxy, the Milky Way, was formed. Other planetary systems may have appeared over the months of June, July and August, but our Sun and Earth only formed in mid-September. Life on Earth appeared soon after. Where do humans fit in? Well, everything we have done, everything we have accomplished across our entire existence as a species, happened on a small bright dot at the lower right hand corner of the calendar, on the last second of December 31. Everything in our recorded human history happened in the blink of an eye…

We look back to the ancient civilizations and wonder, man those things happened thousands of years ago, and yet, those many millennia that have past are but a single flash in the history of our entire universe. It makes all we have done so far on our tiny planet called Earth seem so insignificant, when we compare it with the infinity of space and eternity of time.

And so we have come to an important crossroad: are we going to squander everything away in war and conflict in the next second of this calendar? Or are we going to put aside our differences and work towards something greater for knowledge, for the future? You decide.

(inspired by ‘Cosmos – Episode 1 – The Shores of the Cosmic Ocean’, by Carl Sagan)
