JF Ptak Science Books Quick Post An entry in the series A History of Blank, Empty, and Missing Things
[From Rex Knight’s odd aether-waves work, Wake Up and Sleep!, 1938]
The good estimate of the number of people who have lived on the Earth is about 100 billion.
I wonder about the resting results in their lives, of their sleeping adventures, of their dreams.
If the average age of all people who have ever lived is, say, 30 years, that makes 3 trillion years of living, or about 1 quadrillion hours.
Let’s say that everybody got six hours of sleep for about 165 trillion hours; and let’s say that people dream, say, five times per not, that makes, again, about a quadrillion dreams.
If we in general burn 50 calories a dream, that translates to about 50 quadrillion calories holding up the dreams of mankind.
I wonder where all those dreams have gone?
