“Our feeblest contemplations of the Cosmos stir us — there is a tingling in the spine, a catch in the voice, a faint sensation, as if a distant memory, of falling from a height. We know we are approaching the greatest of mysteries.” –Carl Sagan
34 years ago, Carl Sagan became the first person to present — in a format accessible to the entire world — a synthesized story of all the most important scientific points and facts that we had learned about the cosmic story common to us all.
No longer did we live in a Universe the size of our galaxy, dominated by Newtonian gravity, but in a Universe billions of years old, with more than 100 billion galaxies in it, that all started with a bang. But since 1980, we’ve learned so much more, and some of the best ideas that Carl knew — about the beginning, middle, and end of the Universe — have actually been improved upon, and the story as it was told in 1980 has been superseded by a more accurate one.
