Exponential growth: How folding paper can get you to the Moon

Check out our Patreon page: / teded
Can folding a piece of paper 45 times get you to the moon? By seeing what happens when folding just one piece of paper, we see the unbelievable potential of exponential growth. This lesson will leave you wanting to grab a piece of paper to see how many times you can fold it!

[@AlbertTheGamer-gk7sn]

By the way, here is something called dimension compression. You start with a rectangle with dimensions 1x2. It has an area of 2 square units. However, if we were to move the line on top of the rectangle to the midpoint, the bottom line will double in length, assuming the area of the rectangle remains constant. Then, it will have dimensions of 0.5x4. If we keep dragging the top line as the space becomes infinitesimally small as the 2 lines converge on top of each other, we will get a line that extends infinitely; a dimension. We can do the same thing with a 3D cube, where we will compress the top square to the bottom one which increases it to extrude it into a flat 2D plane. Therefore, we can theorize we are living in a 4D tesseract where the top cube is compressing against the bottom cube, causing the universe to expand at negative velocities. When the top cube lies on top of the bottom cube, the Big Rip will happen as the bottom cube gets an infinite 3D volume. Therefore, if you want to extrude something into the 4th dimension, you must make them infinitely large in 3 dimensions, and then pull the top cube out of the bottom cube, which will shrink the tesseract back to finite dimensions. Therefore, if we divide by 0, we can create an infinitely large Rubik's cube and pull the cubes away to create the first 3x3x3x3 Rubik's tesseract.

[@JustWasted3HoursHere]

I remember reading somewhere years ago - and it seemed as incredible as this one - that if you could fold a piece of paper 100 times it would actually be taller than the KNOWN UNIVERSE is wide. That is, it would be about 16.7 *BILLION* _lightyears_ tall. Doesn't seem feasible until you start actually doing the math. Another one similar to this is the one where you hire someone to work for you for 30 days, but you're going to pay them every day double what you gave them the day before, but you will start with only 1 penny. So, on day two you will give them 2 pennies (so now they have 3 pennies, etc). How much would they have at the end of the 30 days? Almost 11 million dollars!

[@notydino]

When you fold a 1meter length paper 40 times, the length/width would be reduced to 9e-13m. I believe this is smaller then the size of an atom. The paper tower would be so thin it couldn't hold together at the sub atomic level. So even as a hypothetical discussion, the concept doesn't hold water very well.

[@JupitersDancer]

You forgot to take in account that when you fold 40 times, you actually only fold 20 times the width and 20 times the height. For example if a paper of one squared meter is folded once, either the width or the height is still 1m long. So when folded 40 times, the sides are still about 0.9 microns long...

[@spectrum6474]

[@thealexguy1486]

So let's say we take an average newspaper, 4800cm^2. When this is folded in half the area halves and becomes 2400cm^2. As you continue to fold the paper in half, the area keeps shrinking resulting in 45 folds making a piece of paper of size 0.0000000001cm^2, which is 140 times smaller than a carbon atom (which is inside a molecule of paper), therefore if folding paper more than 7 times was possible, 45 times would result in an atom being split meaning you couldn't get it to the moon.

[@justinmarkrivera5092]

Shaurya Sharma well, if you can fold a paper that thick then maybe since getting up to 10 folds is barely doable. Mythbusters even got up to 11 and the used a large wide paper and used a steam roller just to flatten it. Also you have to make it stand up and it having a height of over 6 miles is hard if not impossible unless it had a lot of support.

[@wailimchan376]

by the time u get to around 8 folds, the height of the paper will prevent you from making another fold.

[@JA-nv4zb]

Why not fold dirt

[@tabzoo7819]

Shaurya Sharma yea instead of spending 3.4 billion on a spaceship that ur only using once

[@rxhx]

Maybe if the paper was a million miles wide, we could get a visible folded bridge to the moon out of it.

[@dragonmanover9000]

To continue with this mathematical phenomenon, let's come up with an equation for this paper-folding technique. If we think of this as x = t * 2^n, with x being the length of the folded paper, t being the original thickness, and n being the number of times we fold the paper, we can find how large n would be at a certain thickness if we know how thick the paper originally was. According to the video, the thickness of this magical paper is 0.001 cm, or 0.00001 m, or 10^-5 m, so we can use this starting thickness again for this example. Finally, let's come up with a distance we can reach. Since they already used the distance between the earth and moon as an example, let's come up with something bigger, like the distance to the sun. That distance is 150 million km or 1.5 * 10^11 meters. Plugging it in, we get 1.5 * 10^11 = 10^-5 * 2^n, which must mean that 2^n is 1.5 * 10^16. We can find n by transforming the exponent into a log, and so we get the log function log2(1.5 * 10^16), which is equal to 53.736. Since we can't fold the fraction of a distance, we can round it up to get 54 folds. Let's go even further: Distance to Proxima Centauri (4 * 10^16 meters) = 71.760 (72) folds Length of Milky Way Galaxy (1.75 * 10^21 meters) = 87.177 (87) folds Diameter of Observable Universe (8.8 * 10^26 meters) = 106.117 (106) folds

The problem with this is that you can’t do this even if you had an exponentially large piece of thin paper since eventually the folding of the paper literally causes the outer layers to be ripped in half since they are on the outer layers abs can’t stretch that far over each fold.

The moon has also many of those elements but has e.g. a much thinner atmosphere, much less water in form of ice and is inhabitable without astronautic devices. So, what is better for us, the moon or our earth? We need to face it that paper doesn't work the way it is imagined with folding.

[@Saaraayee]

The illustrations is deceptive! The area of the surface of the paper gets smaller and smaller after each fold! So basically it gets as tiny as an atom after being folded for so many times. Which makes it a fun fact but literally impractical and undoable.

@Something Studios it won't matter much because paper is shrinking exponentially..

[@Re5_2karman]

you guys are looking it the other way to figure what causes the impossibility. It's not about how hard to fold the paper, heck just forget folding and stack the paper instead, though it wouldn't still work since the bottom part of the stack can't handle the immense pressure that would already explode before you reach the moon Not to mention other factors like budget and weather effects which shouldn't be brought to this discussion

Wouldn't the folded paper be extremly thin? I don't know how to explain it well, but wouldn't it be like a 'tower' that is insanely thin yet really tall? (just ignore me if it makes no sense, or is simply false. Never was good in science)

[@emperorgluteusmaximus7069]

You're correct. Each fold decreases the surface area of the paper by half. This is all theoretical of course. It's obviously impossible.

Instant Crush when u fold it, the thickness, if u measures the folded (lets say papers) hight it would have been doubled. Just like if you folded a blanket many times over, after each fold, you would find that it takes up more hight, while other dimensions may shrink

[@jeremyshaferorigami]

It would also have to be EXTREMELY stretchy paper because the top layer on the moon would be "next" to the bottom layer on the earth and it would be curving around all of the other layers, unless you want to assume the paper has zero thickness in which case it wouldn't get off the ground.
