Take note that all of these calculations are mere estimates even though powerful telescopes have already invented and used by our modern astronomers and star gazers. The calculation of the stars in the Milky Way alone is a mere estimate. How much more our calculations of stars in the whole Universe, where the number of galaxies which contains numerous stars, are also roughly estimated? Read more
