'You'll never get your head around how big the universe is,' warns astronomer Pete Edwards of the University of Durham in this film about measuring astronomical distances. 'There are as many stars in the universe as there are grains of sand on the Earth.' So how far is a light year? And supposing our galaxy were the size of a grain of sand, how big would the universe be?

More Stars Than Grains of Sand: A Universe of Truly Fantastic Numbers

Based in part upon David Blatner's book, Spectrums, this little film explores how there are more stars in the universe than grains of sand on earth. Yet, in just one grain of sand there are more atoms than all the stars combined in the cosmos. We truly live in a universe of fantastic numbers.

Are There More Grains of Sand Than Stars?

This question comes from Sheldon Grimshaw.

I've heard that there are more stars in our Universe than there are grains of sand on all the beaches on Earth. Is this possible?

Awesome question, and a great excuse to do some math.

As we learned in a previous video, there are 100 to 400 billion stars in the Milky Way and more than 100 billion galaxies in the Universe - maybe as many as 500 billion.

If you multiply stars by galaxies, at the low end, you get 10 billion billion stars, or 10 sextillion stars in the Universe - a 1 followed by 22 zeros.

At the high end, it's 200 sextillion.

These are mind bogglingly huge numbers.

How do they compare to the number of grains of sand on the collective beaches of an entire planet?

This type of sand measures about a half millimeter across.

You could put 20 grains of sand packed in side-by-side to make a centimeter. 8000 grains in one cubic centimeter.

If you took 10 sextillion grains of sand, put them into a ball, it would have a radius of 10.6 kilometers.

And for the high end of our estimate, 200 sextillion, it would be 72 kilometers across.

If we had a sphere bigger than the Earth, it would be an easy answer, but no such luck. This might be close.

So, is there that much sand on all the beaches, everywhere, on this planet?

You'd need to estimate the average volume of a sandy beach and the average amount of the world's coastlines which are beaches.

I'm going to follow the estimates and calculations made by Dr. Jason Marshall, aka, the Math Dude.

According to Jason, there about 700 trillion cubic meters of beach of Earth, and that works out to around 5 sextillion grains of sand.

Jason reminds us that his math is a rough estimate, and he could be off by a factor of 2 either way. So it could be 2.5 sextillion or there could be 10 sextillion grains of sand on all the world's beaches.

So, if the low end estimate for the number of stars matches the high end estimate for the number of grains of sand, it's the same.

But more likely, there are 5 to 10 times more stars than there are grains of sand on all the world's beaches.

So, there's your answer, Sheldon. For some back of the napkin math we can guess that there are more stars in our Universe than there are grains of sand on all the beaches of Earth.

Oh, one more thing.

Instead of grains of sand, what about atoms?

How big is 10 sextillion atoms?

How huge would something with that massive quantity of anything be?

Pretty gigantic. Well, relatively at least. 10 sextillion of anything does sound like a whole lot.

If you were to make a pile of that many atoms... guess how big it would be.

It'd be about.... (gesture big then gesture small) 4 times smaller than a dust mite.

Which means, a single grain of sand has more atoms than there are stars in the Universe.

How Big Is The Universe?

Carl Sagan told us that there are more stars in the universe than there are grains of sand on all of the Earth's beaches. At the same time, there are more H2O molecules in just 10 drops of water than there are stars.

Ranging from the unimaginably small to the unimaginably big, the scale of the universe is mind-boggling. Watch to try to wrap your head around it.

Beyond Infinity Number Comparison

Lets count from one to a a million, a googol, Graham's Number... all the way till infinity, and even how to count beyond infinity, into the uncountable infinities! We journey to see what amount of quantity for the all the people on earth, all the ants on earth, all the atoms in your body, all the stars in the universe and beyond. Every single mind-blown number you can think of, going bigger than infinity... this gets even more extreme!

Kindly note several errors in the video (thanks to our viewers for spotting them):
69 should be the number of companies exceeding USD $100 BILLION as opposed to million.
172,000 is the usable words in Oxford Dictionary, the actual number is likely close to a 300K.
The number of data bytes ever created should be 10^22 instead of 10^20. The figure for 10^20 is outdated.
The number presented is not a Googolplex to the power of a Googolplex but rather 10^10^(100*(10^10^100)). Likewise for the Googolplex 3 times.
The figures for the number of games are the lower bound, as opposed to the total number of games.
The largest prime given should be the largest KNOWN prime found as of 2019.
The simplified version of infinities are incorrectly described. The ordinals should be ω•2, ω•3... instead of 2ω, 3ω...
The infinity symbol for inaccessible infinity is denoted as I instead of ε0, where ε0 refers to inaccessible from ω^ω...
The infinity symbol for indescribable infinity is denoted as Πn_m instead of ζ0.
The correct order would be ω, ω+1..., ω•2..., ω^ω...,ε0..., ζ0..., Γ...,ω_1...
A rectified version incorporating different elements and items will be coming soon...
