Astronomers say there are more stars in the universe than there are grains of sand on all the beaches on earth. How do they know how many grains of sand there are in the whole world?
In: Mathematics
Posters have offered a number of explanations and math. But what it really comes down to (just in my opinion) is… everybody’s guessing. They’re guessing about the sand and they’re guessing about the stars. Sure, they may be educated guesses. But you know what, these are really big numbers no matter how you do it, and it really doesn’t matter whether there’s more sand or more stars because it doesn’t matter and because we can’t really get our heads around those big numbers anyway.
In conclusion:
Grains of sand: Lots
Stars: Lots
