      @neiltyson I don't know who to ask; are there more stars in the sky than grains of sand on Earth? A debate with wifey.

      They are about the same: Stars in the observable universe & grains of sand on all the world’s beaches.

          You said "on the world's beaches." Does that mean that if you include deserts and ocean floors, there are more grains of sand than stars?

          If the universe is infinite, then there are infinite worlds, with an infinite number of grains of sand, right?

          Just a misunderstanding..I took "all the world's" as all of the worlds in the universe, not as all of this world's

          Well there still isn't an infinite number of worlds in the universe, as there is a finite amount of mass and energy.
