how many grains of sand would fit in the universe

How many grains of sand can fit inside the sun? Then 1,000,000 grains of sand would fit in one cubic inch (100^3). Finally we’ll ball park estimate the size of beaches on the West Coast of North America. But what is there to count the grains of sand on the Earth. Picture such a cube of sand; it contains roughly as many grains of sand as there are stars in the Universe. Also, when talking about so many grains of sand, I suppose the size of the grain would have a significant change to the number. one grain of sand has a volume of 1.3 * 10^-9 cubic feet (from gomath.com) Some people on abc.net.au tried to figure out how many grains of sand are on earth. There are one million cubic centimeters in a cubic meter. How many grains of sand would there happen to be in say a gallon of milk? And supposing our galaxy were the size of a grain of sand, how big would the universe be? Let's start with the Earth. So now we know the number of atoms in a gram of sand, we’ve got to figure out how many grains of sand there are in a gram and multiply it by the number of atoms in that same weight. And similarly to fill up a cube a metre on a side takes 10 thousand, times 10 thousand, times 10 thousand, or one with 12 zeros after it, or 10 to the 12 grains of sand. It may hurt your brain to think about it, but it … Given that there are one million cubic centimeters (cm3) in one cubic meter (m3), how many grains are there in 1 m3 of sand? It was a primitive system in which letters became numbers: A = 1, B = 2, C = 3, etc. 1. The question the way it is stated is unanswerable.The size of the universe is unknown. It does not deny the current size of the universe, but still―our entire universe, with all its energy, its matter and all that space in between―could still fit into a grain of sand. In order to do this, he had to estimate the size of the universe according to the contemporary model, and invent a way to talk about extremely large numbers. a. Grains of sand are very smal about 2600 grains fit in one cubic centimeter (cm). They said, if you assume a grain of sand has an average size and you calculate how many grains are in a teaspoon and then multiply by all the beaches and deserts in the world, the Earth has roughly (and we’re speaking very roughly here) 7.5 x 10 18 grains of sand, or seven quintillion, five hundred quadrillion grains. That's more than all of the grains of sand on Earth. If there are already more stars in the universe than there are grains of sand on the beaches, think about how many planets there are. He notes that is similar to the number of grains of sand on every beach in the world. A large construction wheelbarrow would contain the Milky Way, the galaxy in which our sun resides. 3. Are there really more stars in our universe than there are grains of sand on all the beaches on Earth? The trouble Archimedes faced was the Greek number system. So 8,000 grains could fit in one cubic centimeter. Sand: Next we’ll measure actual sand grains and then estimate how many grains fit in cubes of increasing sizes. Scientists estimate the number by measuring the average size of a sand grains, then calculating how many sand grains … There are a lot of sand grains on Earth. If a medium grain of sand takes up 0.5 mm of space (0.0005 cm 3) and 1 cm 3 of sand weighs ~2.8 g then one medium grain of sand weighs about 0.0014 g (1.4 mg) 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. So that’s how many grains of sand in a cubic metre. How many grains are in 1 cubic meter of sand? There might be as many as three sextillion stars in the universe. ς, Psammites) is a work by Archimedes, an Ancient Greek mathematician of the 3rd century BC, in which he set out to determine an upper bound for the number of grains of sand that fit into the universe.In order to do this, he had to estimate the size of the universe according to the contemporary model, and invent a way to talk about extremely … Whether that is true or not, I don't know. ... the number would be several orders of magnitude greater than all the matter of the universe. Then we’ll see how many sand grains we need to represent our own Milky Way galaxy. Yates puts it … The volume of the Earth is about 10 21 cubic meters. As such, 10^11 cubic meters of sand contains roughly 10^11*10^10=10^21 grains of sand. But when calculating the total volume, we’ve got to remember that Sars-CoV-2 particles are extremely small. I'm just curious. That's 3 followed by 23 zeros, or 300,000,000,000,000,000,000,000. Let's say one grain of sand is 0.01x0.01x0.01 inches cubed. It is not even known as of yet if the universe is finite or infinite. If you counted one grain of sand each second, how many seconds would it take you to count all the grains in one cubic meter? Calculating likewise, 8,000 grains would fit in 1 cubic centimeter. So let's consider how many grains of sand would be needed to fill up our star, the Sun? The Sand Reckoner is a work by Archimedes in which he set out to determine an upper bound for the number of grains of sand that fit into the Universe. This is comparable to the number of stars within the observable universe, being only 1 order of magnitude lower. Source: Glasshead/Newton Sun 10 Feb 2013 22.11 EST First published on Sun 10 Feb 2013 22.11 EST c. What the guy in the video was saying was most likely just an estimate, not an exact figure. Hypertextbook.com says the volume varies between 1.13 √ó 10-13 m3 and 4.85 √ó 10-9 m3; There’s a group of 13 people that spent 1,000 hours counting 3,281,579 grains of sand. The point is this - that between 10 19 and 10 87 there are more than enough orders of magnitude to account for every atom in the universe. Or if I fill up a square a metre on a side I’d need about 10 thousand lines of 10 thousand grains. $\endgroup$ – Andrew Aug 9 '11 at 3:13 Grains of sand are very small, about 2500 grains fit into one cubic centimeter; a cube one centimeter on a side (about the size of the tip of your little finger). Sand constitutes a major fraction of the makeup of Earth. There are this many cubic meters in a cube 4642 m on a side (about 3 miles). Arranging 10 sextillion grains of sand in a circle would have a radius of 10.6 km. That's an impressive amount of sand. For ages 12 and older. I am also aware it depends on the sign of the grains of sand and i would just say to find a number and stick with it. A thimble would hold all the starts visible on a clear, dark, summer night. You could line up 100 grains of sand and they would be 1 inch long. Now, if you were wondering how many grains of sand it would take to fill the observable universe, this question could be answered. David H says: In order to do this, he had to estimate the size of the universe according to the contemporary model, and invent a way to talk about extremely large numbers. It is roughly the same as the number of grains of sand on the planet. We can't conclude for certain, then either way, because we may certainly be off by an order of magnitude or two in either direction. FEB 18, 2021 - Perhaps you’ve heard this before: There are more stars in the universe than all the grains of sand in all the beaches, desserts and sandboxes on Earth. Always important to define your terms. Then he calculated not just how many grains of sand there were on the beach, but how many there were in the universe. That's 3 followed by 23 zeros, or 300,000,000,000,000,000,000,000. You could put 20 grains of sand packed in side-by-side to make a centimeter. 6. There might be as many as three sextillion stars in the universe. The exact size does not matter to me that much. The work, also known in Latin as Archimedis Syracusani Arenarius & … 1,000,000 x 12^3 = 1.728 billion grains of sand per cubic foot. 1.728 billion * 27 = 46.7 billion grains of sand per cubic yard. use the following info in you r calculator, the observable universe has a 'radius' of approximately 7.5 * 10 to the power of 13, km, one light year is approximately 1 * 10 to the power of 13, an approximation for the amount of 'volume' in the universe can be found using the formula for a sphere: volume=4/3 pi*radius to the power of 3, where the raduis means the radius of the universe … b. Imagine each grain of sand would be a 1/2 mm. Arranging 20 of these sand grains in a line would measure 1 cm. $\begingroup$ The link calculates grains of sand on beaches. However, the virus is much, much smaller than a grain of sand. ... i know. In Archimedes' The Sand Reckoner, addressed to Gelon, King of Syracuse, he attempted to count the number of grains of sand required to fill the entire universe.Assuming that one poppy-head would not contain more than 10,000 grains of sand, and that its diameter is not less than 1 / 40 th of a finger's breadth, and assuming that the sphere of the fixed stars, which was to Archimedes … "Imagine that each star in the known universe is represented by a single grain of sand. No one knows how many starts there are exactly in the universe, but your guess of 10^22 seems fair. The size of the universe and the number of stars (in SAND GRAINS!) Which, after a bit of fun converting units, we find is equivalent to 8,000,000,000 grains of sand per cubic meter. This is a problem that the Greek mathematician Archimedes tried to solve in the third century B.C. There could be 2x to 10x more planets than stars. This is an impressive Universe. ς, Psammites) is a work by Archimedes in which he set out to determine an upper bound for the number of grains of sand that fit into the Universe. How many grains of sand would it take to fill the universe? Most of the volcanic sand you mention is probably at the bottom of the ocean or mixed into sandy loam soils. That's more than all of the grains of sand on Earth. So if we assume that an average of 20 grains will fit along each side of a 1 cubic centimeter box of sand, we find that there are about 20 x 20 x 20 = 8,000 grains per cubic centimeter. To find how much grain of sand you would need to have …
