How can our life span be compared with the age of the universe?
I assume that there is a certain idea of standards in space. Now let’s do the same for the time factor. Please imagine the entire history of the universe, from the Big Bang to the present day, we would represent in only one year. ……….and this history would then be shown in the form of a cosmic calendar of us.
The Big Bang then takes place at the beginning, namely January 1, and today corresponds to just midnight on December 31. In the 14.5 billion year old universe (has been researched), each month of the cosmic calendar corresponds to a little more than a billion years. 14,5/12
In this timescale the Milky Way was formed sometime in February. In the following cosmic months many star generations existed and passed away again.
Quite incidentally, they enriched the Milky Way with the „stardust“ of which „we“ and our planet consist. Our solar system, which we hopefully already know, and the Earth did not form on this scale until the beginning of September. In real time this corresponds to about 4.5 billion years……..and on we go. Already at the end of September the moving life (in water and on land) on earth began. These creatures remained relatively simple and microscopically small for most of Earth’s history. Larger living beings appeared on the scale of our Cosmic Calendar only in the middle of December and…….the early dinosaurs did not appear until the second day of Christmas. These disappeared, as known with a „cosmic wink“ – presumably by the impact (streak) of an asteroid or comet (maybe also minor planets). So back to the real concepts of time, the dinosaurs died out 65 million years ago, in the cosmic calendar this was again (also known) only yesterday. Now after the disappearance of the dinosaurs small furry mammals populated the earth.
So and quite normally further on in a temporal limited scale, about 60 million years later, on December 31st at about 9 pm, early hominids (the ancestors of mankind) started to walk upright………..and perhaps the most amazing thing about the cosmic calendar:
The entire history of human civilizations fits into the last half minute. On this scale, the ancient Egyptians built the pyramids only eleven seconds ago. A second ago, Kepler and Galileo proved that the Earth moves around the sun, not the other way around. The average student was born about 0.05 seconds ago, around 23:59:59.95. On the scale of the cosmic calendar, mankind is the youngest child and a human life lasts no longer than the blink of an eye.
So now think and reflect…..
