A whopping bang, putting it ALL together and… into perspective

Posted in den_library on Feb 28, 2010

How fragile we are, yet, like Sagan loved to say-

“we are all star stuff, literally. ¬†Every atom in our bodies with the exception of hydrogen can be traced to a red star billions of years old.”

THE BIG BANG

by Alexander Green. excerpt from his, Spiritual Wealth; ‘coming of age in the milky way’

Imagine that the 13.7 billion-year history of the universe is compressed into one calendar year. The Big Bang occurred in the very first second of January 1 and the current moment is the last second of the last minute of December 31. Using this compressed timescale, each month equals a little over one and quarter billion years. Each day represents 40 million years. Each second covers 500 years of history.

The Milky Way coalesces in March. The sun and planets form in August. The first life – single celled – show up in September, the first multi-cellular organisms in November. The first vertebrates appear on December 17. Dinosaurs show up on Christmas Eve. (And become extinct on December 29.) Modern humans finally appear at 11:54 p.m. on December 31. And all of recorded history occupies the last ten seconds of the last minute of the last day of the year. The pyramids were built nine seconds ago. The Roman Empire fell three seconds ago. Columbus discovered America one second ago.

Yet we should feel some pride and astonishment, too. It took less than an hour to make the atoms, a few hundred million years to make the stars and planets, but more than ten billion years to make human beings
