Gazing at the stars above, do you know that you are actually looking at their past? Light from the sun takes about 8 minutes and 20 seconds to reach the earth. So, when you are looking at the sun, the sunspots that you see, the eruptions and the wild mechanics of the solar wind are about 8 minutes and 20 seconds old . It takes about 4 years for light to ravel from the Alpha Centauri (the nearest star to earth) to earth. So when you see what you see it’s the past. You are looking at what happened four years before from now.

Suppose there is another planet out there teeming with intelligent life , 1000000 light years from us, when they look at us, they are not gonna see the clutter of buildings or advanced human life. They are gonna see tyrannosaurus, spinosaurus and giganotosaurus, and the dense coniferous jungles ,scrublands and riparian forests.

On a clear starry night, when you  look out at the gazillions of stars  above, think about this and revel in the mystery that is our universe.
