Not saying youre wrong....but how does one prove that?there are more stars than sand on the earth.

Let n = all the sand on earthAsk an autistic with OCD...
That was a cheap response, I apologize (it's insincere, but you deserve an apology.)
So, you can do it a couple ways. You could actually count the sand on the planet. As it's not infinite, and then count stars, until you hit 1 more... Or, you could do a bunch of really goofy math, crazy math involving a shit ton of boundaries, like "what is a pebble of sand?" It must be defined, as does "what is a star?" Count black holes? They're just super-dense stars, they've imploded and are actually brilliant, but the light can't escape the gravity (remember the "does light have mass thread? That's one way to prove light has mass... Only objects with mass can be affected by gravity.) How small can it be, before it's not a star? Does it have to be actively ignited? Can we count supernovas? And then, you figure out the size, approximately, of the universe, based on an expansion at the speed of light for 13.1 billion years, calculate galaxy density in the visible distance, and extrapolate from their, giving a margin of error of 50%+/-. With that margin of error in tact, and given math to approximate the "number of pebbles of sand" and then calculate the approximate number of stars. If the number show, unequivocally (i.e. double the margin of error, not mathematically, but numerically, and still have a difference greater on one side than the other.)
Basically, it's "theoretical," but, it's a pretty fuckin' solid theory.
But you are comparing the size of the universe to the amount of sand.Let n = all the sand on earth
Let s = all stars in universe
Earth is finite, and because n is a subset of earth n is finite. Currently the universe is expanding and infinite and s is a subset of universe. It follows s is hypothetically infinite. Therefore it would always be at least s >= n+1 by definition within our accepted physics.
Minne you really took the roundaboutation way LOL and I'm on brain2.0 (the stoopid years), as well!
Matter in the observable universe is finite but not in the infinite universe.But you are comparing the size of the universe to the amount of sand.
Matter in the universe is finite.
It is currently estimated that the visible* Universe contains approx. one-tenth of a mole of stars. A mole is Avogadro's number, 6.022 x 10E23, times what's being counted. So 6 x 10E22 stars/universe.Ask an autistic with OCD...

Nope. Desert sand, sand in soil, sand washed onto the sea floor and on and on. Sand is one of the most awesomely durable mineral parts of the earth's surface. The only way to really remove it is to melt it, and then when the magma cools and is weathered, you get ... more sand.I started counting sand to prove one of you right.. are we talking beach sand only or?
