how many grains of sand are there in the world, if people say there are more stars than this amount?

Answer 1

people say that because there is an exact amount of sand on earth (obviously a very large, uncountable number) but many people believe that space is infinite, which means that there is probably an infinite amount of stars

Answer 2

Sand on earth is always being created by erosion, there is no definite answer to this because more sand is always being made.
If you knew exactly where and when each of these grains of sand were made you could make an exact equation that could give you a hard number, of
(how many grains of sand are being made each year)+(how much sand we had to begin with)=total amount of sand we have on the planet this year.
Otherwise you need to figure out a round about number of how many grains of sand we have and how much is being created by erosion.

This is exactly the same as the universe. Galaxies and stars are constants being created and destroyed, so unless you know the rate at which any of these are made(or destroyed) there is no way to give an exact number.

Answer 3

The number of galaxies in the universe may be very hard to estimate.
90% of the visible galaxies don't exist to-day.
The universe is a finite entity and has a maximum size.
It is all housed in a sphere with a radius of about 6 billion light years.
If I had to guess I would say the number of grains of sand on earth exceeds the number of galaxies in the universe.

Answer 4

I believe the universe in infinite, in which case there could be more stars than grains of sand on Earth, that is how big infinity is.
But I doubt there are more stars than grains of sand, because there would be an infinite number of planets with sand on.
And there are loads more grains of sand on Earth than stars we know about.

Answer 5

A whole heckava lot... makes you think huh? Somehow we can experience a grain of sand and a big star all in the same day. It's kinda neat, aye, being apart of all the wonders of the universe... Seems like there's enough space out there, that anything is possible.

Cool thought, thanks...

Answer 6

There are approximately 8.5 * 10^21 grains of sand on earth. That is 8.5000000000000000000000, or, to simplify things, a he## of a lot.

Answer 7

There are a lot.
Put the biggest problem
with both sand and stars
is that both are far fewer
than the number of silicon
atoms in the galaxy.

Answer 8

36

Answer 9

seemingly stars can multiply,but sand cant,so there are more stars than grains of sand.

Answer 10

Approximately seven quintillion five quadrillion (7,500,000,000,000,000,000) grains of sand.
