If the 13.8 billion-year history of the universe is compressed into one year, in which month did humans appear? May? September?
The cosmic almanac proposed by the famous popular science author and astronomer Carl Sagan in "The Dragon of Eden" will make you drop your jaw.
Let's take a look at the moment when the great events of the universe, the earth and mankind all appeared!
If you compress the history of 13.8 billion years into 1 year, it is obvious that time has accelerated. In this calendar, every second in the calendar is equivalent to 438 years, one hour on the calendar is equivalent to 1.58 million years, and one day on the calendar is equivalent to 37.8 million years.
In this cosmic calendar, a person lives to be 80 years old, and the universe has only passed 0.18 seconds.

In the cosmic calendar, Confucius was born 5.8 seconds before midnight on December 31, and Newton was born before 0.76 midnight; at 0.02 seconds before midnight (calculated by the time Sagan wrote the book), we just had the Internet; and by May 7 next year, the sun will enter the old age of life and become a white dwarf. Where will humanity go then?
