“We humans appear on the cosmic calendar so recently that our recorded history occupies only the last few seconds of the last minute of December 31st.”
-Carl Sagan
The Cosmic Calendar is a concept presented by famous astronomer Carl Sagan. In this diagram, the 13.8 billion year history of the universe is condensed into a single calendar year with the Big Bang happening on January 1st and recorded humanity being comprised in the last day of the last month of the last minute in which we exist.
This concept is so interesting to me as our history as humanity is only in the last few minutes but in reality it’s been hundreds of thousands of years since we’ve been here. I often think about the quote that says “too late to explore the Earth, but too early to explore the Universe,” (which comes from a meme, mind you) because it’s sooooo true. We have the math and such to date us back, but not the technology to actually move at the speed of light to explore the things we are discovering. It’s also so interesting because all of this progress in technology has been done in relatively such little time compared to the universe!

One response to “The Cosmic Calendar 🪐”
“Too late to explore Earth, yet too early to explore the Universe” strikes such a chord with me. I agree that this is such an unfourtunate fact, and as we learn about astronomy and how massive and limitless the universe is, it saddens me we will most likley not figure out intergalactic travel by the end of my lifetime. Also to go off what you brought up, considering what a small portion of the calendar we are I wonder if someday when humans are gone will we even be worth mentioning at all?
