There are more stars in the universe than there are grains of sand on earth
This is the second episode of StunningFactsHD on this episode I describe how there are more stars in the universe than there are grains of sand on earth. This phenomenon was worked out by Scientists, they began by calculating The average size of a grain of sand and by calculating the number of sand grains in a teaspoon. Then the number of beaches and deserts in the world were factored in. The number of grains of sands is astonishing it comes to 7.5 x 10^18 Calculating the number of stars is even harder. Scientists estimated the number of stars that are potentially observable by Hubble If you include every object that twinkles in the night sky, from ordinary stars, to quasars, to red dwarfs, to whole galaxies. The number of stars comes to 7 x 10^22.
