    How big is the universe ... compared with a grain of sand?

    '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?

  • Mind Blowing! ...Earth Compared To The Rest Of The Universe - Amazing Graphic Presentation

    Music: Doggy (Spacey Pooch Mix) by Dhruva Aliman - - Spotify - - “There are more stars in our Universe than there are grains of sand on all the beaches on Earth.” 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.

    The estimates and calculations made by Dr. Jason Marshall, aka, the Math Dude are that, there about 700 trillion cubic meters of beach of Earth, and that works out to around 5 sextillion grains of sand.

  • How Big Is The Universe?

    3:50

    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.

  • If the universe is only 14 billion years old, how can it be 92 billion light years wide?

    9:47

    The size and age of the universe seem to not agree with one another. Astronomers have determined that the universe is nearly 14 billion years old and yet its diameter is 92 billion light years across. How can both of those numbers possibly be true? In this video, Fermilab’s Dr. Don Lincoln tells you how.

  • How far away is the Nearest Star?

    5:08

    Distances in space are huge, but it's difficult to visualise just how far things are away, so I thought I'd have a go at showing how far away the nearest star to the Sun is, by creating a scale model, shrinking the Sun down to the size of a golf ball. The scale is roughly 33 billion:1.

    All distances shown are straight line distances from my start location just south of Manchester in England. The actual distance travelled is larger. The nearest star is actually quite some distance away! And this is just the nearest star - some of the visible stars are many hundreds of times further and the centre of our own galaxy is 7,000 times further away just for starters.

    How Big Is THe Universe? Earth Size as a Grain of Sand.

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

    2:33

    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?

    3:46

    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 Compared to a Human!!!

    5:35

    From the smallest thing (Well, not exactly a 'thing' but a scale) in Universe (Planck Length) to the observable universe this size comparison of the universe will show you just how big our universe is. This animation somewhat compares the size of a human to that of the universe.

    The observable universe is a spherical region of the Universe comprising all matter that may be observed from Earth at the present time because light and other signals from these objects have had time to reach Earth since the beginning of the cosmological expansion. There are at least two trillion galaxies in the observable universe, containing more stars than all the grains of sand on planet Earth. Assuming the universe is isotropic, the distance to the edge of the observable universe is roughly the same in every direction. That is, the observable universe is a spherical volume (a ball) centered on the observer. Every location in the Universe has its own observable universe, which may or may not overlap with the one centered on Earth.
