on all of Earth's beaches? That's a lot.

A few years ago a group of astronomers did a careful survey of the sky and concluded that the total number of stars in the entire universe was approximately 70-sextillion (..that's 70 followed by 21 zeros..)
Nobody has ever counted the total number of sand grains on all the beaches on Earth.

As hard as it is to comprehend, it is true there are more stars in the universe than grains of sand on all of earth's beaches. Now for the explanation: The number of grains of sand on all of earth's beaches represents a finite amount. That means that, while it wouldn't be practical to expect to have an exact count of sand grains, it is still possible. The universe, on the other hand, is infinite. There is no end. It goes on for ever. As a matter of fact, the Hubble telescope recently discovered heretofore unknown regions of the universe that are loaded with billions and billions of galaxies, with each galaxy containing billions of stars. Hard to comprehend, but factual.

Probably a whole lot more stars in the universe than grains of sand on the beach, actually.

there are about 10^22 stars in the visible universe, which is almost certainly not the whole universe, which may actually be infinite in spatial extent. the whole earth's mass is only 6*10^24 kg, and a tiny fraction of that mass is due to beaches. there are way more stars than grains of sand.

To say that there are as many stars in the universe as grains of sands on all of the Earth's beaches, is to give us a sense of the unimaginable vastness of the cosmos. It is a paradox that we can understand, with precise calculations, a star's mass, temperature, composition and fate, yet we will never be able to count the precise numbers of stars that exist.

Yes, i am also sure that the number of grains of sand on earth is not even close to the number of stars in the universe.

No, it is not true.
There are FAR more stars in the universe than grains of sand on all the Earth's beaches.

In the universe? Are you kidding me? There may even be more solar systems, more galaxies out there, much less stars. The size of the universe is beyond our comprehension.
