Ok. I need to know if it's true that there are more stars in the universe than grains of sand on earth. I don't know what I shoud believe. It doesn't seem possible, but, if you think again the universe is like 50 million times bigger than earth. So can anyone tell me the truth. Please!

According to the astronomer Carl Sagan of "Cosmos" fame, the statement is true that there are more stars than grains of sand. Just our galaxy, the Milky Way, has at least 200 billion stars and there are hundreds of millions of other galaxies so the statement is the truth.

Yes there are many more stars than there are grains of sand in the Earth. The earth is about 4000 miles radius or about .1 trillion cubic miles. Sand is a surface phenomenon. If we assume that sand was 10feet thick over the entire surface of the earth then there would be about 10^15 cubic feet of sand. If there were a million grains of sand in each cubic foot then there would be about 10^21 grains of sand.
Where you got the 50 million number, I don't know, but the galaxy we are part of is bigger than that. The Universe is really big. We have been able to see things a few Billion light years from here. One light year is more than 5 trillion miles. The galaxy is many thousands of light years across and has over a billion stars. In the known universe there are a few hundred trillion galaxy's. that means there are something on the order of 10^23 stars in the observable universe.

Yes it is true !

I would refer you to the Deep Field Image, that the Hubble came up with. You will soon find that the count of stars has to be of greater
number, given the small patch that the Deep Field Image represents, once it is factored...!


So how many grains of sand are there in the world? You could start off by trying to guess how many grains of sand there are in a spoon of
sand. Use a magnifying glass to count how many grains fit in a small section. Then, count how many of those sections fit in your spoon.
Multiply the two numbers together to get an estimate. Using this same principle, plus some additional information, mathematicians at the University of Hawaii tried to guess how many grains of sand are on the world's beaches. They came up with 7,500,000,000,000,000,000, or seven quintillion five quadrillion grains of sand.

There are more stars recorded than the
seven quintillion five quadrillion grains of sand.

There are more stars than grains of sand on the earth. With sand,
there is a definite number of particles. The cosmos are infinite...the further you look, the more will be found, forever.

There is an old saying in the cosmology world ..

If it could be done .. geologists would have counted every grain of sand and the astronomers would be still counting stars !

wow that's a powerfull calculator! hope they have enough batteries!

The universe is more than 50 million times bigger than the Earth.

There are billions of galaxies in the universe, each containing billions of stars. So yes, there are probably more stars in the universe than grains of sand on the Earth.

Yes, although there is still some debate today about questions like this, if you consider the amount of galaxies (sme 250 billion that only we can see) and countless others that are so far away from what we can see, we haven't recorded yet, the amount of stars each galaxy has would more than combine to far surpass the amount of sand on any planet like the Earth, if you also include that new stars are being born every few million years (our galaxy alone) and others are dying to seed other places in the universe with new stars.

I think if you check Sagan's statement, he said "more that all the grains of sand on all the BEACHES...."

Even so, it is a collosal amount.

You need to multiply 200 billion stars in a galaxy by 200 billion galaxies.

And Jessie, there are single stars that are 50 million times the size of Earth. Even our sun, a very average star, is well over a million times the size of Earth.

Its true and isn't that SO incredible? Every once in a while we find a good metaphor to help us visualize an amazing fact about the universe... this is a good example. Just think of how many beaches you have been to in your life and the vast stretches of desert that cover this planet... and all those grains of sand are but a drop in the bucket compared to the number of STARS. Wow!

Brant is nice. the answer is not any. I used to stay in Florida, and virtually the completed state is sand, even one hundred miles from the sea. there is likely more advantageous grains of sand in simple terms in Florida than there are stars in the entire universe. relying on what length grains of sand you concentrate on, from very coarse to very effective, there should be everywhere from 2,000 to sixty seven,000,000 grains in step with cubic inch. a million is a sturdy round volume, nicely interior that variety. the area of Florida is 66,000 sq. miles, so if the sand is 25 feet deep, it truly is 66000x5280x5280x25=4.6x10^13 cubic feet, it extremely is about 8x10^16 cubic inches. Multiply with assistance from a million million and also you've were given about 8x10^22 grains of sand, in simple terms in Florida. our magnificent estimate is that there are 7x10^22 stars in the universe. Screaming Monk, in spite of if Carl Sagan suggested it that doesn't make it actual. This doesn't be the first time I stuck Sagan in an blunders on the topic of mathematics. To all those obtainable who declare there are fewer grains of sand, enable's see some calculations to again it up. I confirmed you mine. Edit: ok, I waited 17 hours and nonetheless no individual who says the answer is "certain" has shown us any type of calculation to again it up. Do the mathematics. the in person-friendly words way i visit verify to justify the answer being certain is in case you limit sand to easily seashores and do not count number deserts or places with sandy soil and in case you take advantage of old old estimates of ways many stars there are in the universe.

i know that it is hard to imagine, but yes that statment is true....our galaxy alone has over a hundred billion stars and our galaxy is an averge size galaxy. there are over a hundred billion galaxies that we can observe. so the number of stars easily surpasses the total number of grains of sand on every beach on planet earth. amazing isnt it!!!!!!
