Time, Life and the History of the Universe in One Easy Bar Graph
I read in Professor Brian Cox’s “The Wonders of the Universe” that the amount of time that the Universe will be hospitable to life is a very small fraction of Time itself—Time being from the very beginning of the Big Bang, to the moment when the Universe completely dissolves away.
I wanted to sketch it out as a bar graph, with the blue area being the amount of time that Life as we know it will be possible anywhere in the Universe, and the red bar being Time itself—from the Big Bang until the distant future when the last bits of matter and energy dissipate into nothingness.
But, to make it to scale…the red bar would need to be very, very long. I was going to need a really wide piece of paper.
