In his book "Cosmos", published in 2008 in Russia with the support of the "Dynasty" foundation, Sagan talks about the evolution of the Universe, the formation of galaxies and the origin of life and intellect.
The author understands that it's quite difficult to imagine a billion of billions or 10¹⁸ seconds. According to modern scientists so much time has passed since the birth of the Universe. To imagine the whole course of events in the history of the Universe he suggested a cosmic calendar that compresses the history of the Universe into a single year. Thus, he described the history of the Universe on the scale at which a "cosmic second" corresponds to the real 500 earth years.
