So what you're saying is.. this perfectly-shaped rectangle... is the bestangle?
Herecy
SACRILEGE
Vote
Hexagon is the best gun or Bestangle
@TheBigNCat but not the bestangle
OH NO WHAT HAVE YOU DONE
I always find it interesting that there are more subdivisions down than we have doublings up. the planck length is at 226, where the observable universe ends at 184
@Zanorok You realize startings twice as big would only shift the number by 1?
Wouldn't it be funny if the unobservable universe ends at 226 subdivisions.
And then we integer overflow into the Planck length.
@Tj H I mean at this point you would be tearing subatomic particles apart. Can we even still call that a sheet of paper?
@Will Postill and thanks for all the fish.🐬🤖
@Zanorok it’s based off the golden ratio. the sheet of paper folds represent that
I find it fascinating how this channel can turn an ordinary piece of paper into an existential crisis for so many people
If you think about it, this is evidence that we may live in a simulation.
In 3d re dering we only render what is necessary. We don't fill the inside of a 3d object with data points to make it an object. We just use triangles to construct its shell.
That is to say: the illusion of matter when most of what is being interacted with is nothing.
Why would this make you feel empty? It inspires me with awe.
@TheSaltyBeard How is this evidence of a simulation? All those particles in a nucleus interact with each in a combinatory way. This ensures any calculation using less particles than the original situation is also slower, because it can't sustain the same level of complexity. Although the speed doesn't matter for a simulation hypothesis using a Zenonian argument (Achilles and the Tortoise), the nucleus itself still counts like a multi-dimensional polyhedron; a multi-particled system. So even though matter looks empty it most certainly doesn't model with the complexity of nothing. Just because we use triangles in simulations, and nature uses triangles in real-life; doesn't make real-life a simulation.
Fun fact: if you divide the longer part of the paper by the shorter part it will give you the square root of 2
I love this mans videos, he takes the most simple topic and makes it into literal documentary
...so I'm honestly impressed metric paper folds in half to the same ratio.
@Melesniannon I mean they probably went from there. They used the golden ratio to make a 1m² sheet and divived it until it was a useful size.
@Søren Hougaard Rasmussen Yes, that's exactly what they said in the video. Even though I am used to working with A4 because it is the European (standardized), I am so impressed by this video and agree so much with all the stunning here in the comments. 🙂
@Damian Pulido it seems like the golden ratio
I think everyone knows about this except Americans who don't use metric paper.
@Damian Pulido fun fact; the Golden Ratio is present in both of those.
I don’t think I’ll be able to look at a sheet of paper again without having an existential, gut-wrenching reality check
I wasn’t aware I was about to go on an existential journey guided by a piece of paper but there it is…
All hail A4, all hail the metric system!
Seriously though. I don't know if this video is meant to be poetic or an existentialist piece, but I love it, for sure.
Metric everything lore: literal universes within a sheet of paper
Meanwhile the US:
An atom is smaller than one football field!
Wow
@Metabloxer no way bro
@Metabloxer yeah but is it smaller than a football field divided by 15000 kings feet minus 17 freedom eagles?
Normal people: "Hey, could you hand me a sheet of paper?"
CGP Grey: contemplates life, existence, and nothingness
Normal people : continues to hold hand out as CGP Grey deepens further into monologue

I just wanted to know about some paper bro
and everything.
@TOLSTOI Agreed. At it's most indivisible, there is energy occupying space. Perhaps the energy is far less dense in some area, but it's there nonetheless. (If you dispute this, look up quantum foam.)
What I liked most about this is that a) I learned that A0 paper exists, b) it is a satisfying, perfect 1m^2
3:50 When I learned about the Planck length in high school physics, I went "Heeey, wait a mi- Oh no."
And the teacher quickly shushed me.
Yeah, life is but a dream.
I like this video bc while it gives me a bit of existential dread, it also helps center me when I'm working on difficult or stressful projects. Helps you find where you are.
This video is very powerful for understanding everything we are as far as scaling goes, but also just goes to show how our own scale, where we live and observe, is really the most important to us because it fits us. The rest of this stuff we know exists, but will never truly observe or understand, at least for a very long time. The things on our scale are explained with our communication, using the senses that are tuned for this level of understanding. Look what we’ve done with the scale we’ve been given, the scale we are bound to. We have limits, but do we really know where they are? The limits haven’t stopped our own expansion of understanding, and unlike a lot of other levels, our scale is full of life, compared to the vast nothingness on both ends. If nothing matters on both ends where nothing happens, I wanna stay where things do happen and I can bring myself to comprehend, but I think that’s more easily said, and I’m probably pretty ignorant compared to what things could be but I just wanna say to those who are having existential crises that it’s not a concern and will never be a concern, in our lifetime. And if it is we can cross that bridge when we get to it.
Me, an Australian who grew up with this kind of paper: yeah our paper system is the best, I know exactly what this video is going to be about.
CGP: The organs of the bee...
Me: Whelp, I was wrong.
Well, when you are young, you think everything makes sense once you learn about it. And then, you learn about America.
Everyone but Americans use it 😂
@whatthefox standardized by German government agency DIN which was adopted by the Common Market the predecessor of the EU.
Who invented it?
In Germany even its weigh and thickness is defined by a norm
I love order of magnitude videos that give comparisons like this. Existential crises are fun. 😀
In today's episode of "that useful information you didn't know where to get"
I was looking for paper dimensions for printer setting for my business(printing on A4 would waste paper in my field)
But this half fold thing simplifies things so much.
This was amazing and I love the former presentation you took. We don't think about it but it's amazing to see the similarities between the infinitely small and the infinitely huge
As a fan of Gas (Mat Jarvis) and yourself, I was pleasantly surprised in the best way possible that this was a spin on his "Microscopic" music video using paper sizing as a metric for the biggest and smallest known stuff in our universe 👌
"You can only fold a sheet of paper in half 6 times. No more than that."
CGP Grey: ...and now we're at the Planck length.
@Mariano Amato Practical mathematicians? You mean like accountants, astronauts, engineers, bankers, astrophysicists, and statistical researchers?
Advanced mathematics is useful to many jobs where theres very clear practical use of their skills.
Adv Maths is why you have a phone and a sturdy house and roads and bridges that last. Without Adv Maths it was quite common to build shoddy bridges that caused massive fatalities bcuz they didnt know all the things they needed to know to calculate the correct methods to avoid such catastrophe.
Adv Maths is why skyscrapers and rockets exist. Adv Maths is why bicycles can stay upright when unridden as long as theyre moving. Adv Maths is how humanity has clawed its way out of the dark caves of the past.
But wasn't there a guy who did it 12 times
@Shockblade if it doesnt have its ratio anymore, you didnt fold in half like the op comment said
@zypity it’s impossible for a sheet of paper to be the smaller than even an atom, since it’s made of atoms. It’s like making a human smaller than a cell.
@Dad congratulations on discovering the practical limitations. Please contact the Nobel society to gather your prize.
Perhaps there's a reason we can only fold a sheet of A4 paper 7 times.
Thank you for the nightly existential crisis. Every night I watch one of your videos to give myself just enough nightmares to ensure I wake up in the morning with my heart already racing!
I was expecting an innocent video about A4 paper and then you made me question my own existence. A nice way to start my Saturday morning :))
Genuinely didn't know that the A paper system was also metric, that's neat!
"Hey Grey, look at this sheet of paper for a second."
Grey: (transcends reality)
He has achieved the Psijic endeavour
Yeah, I'd have loved to be there when grey got the idea for this video.
Paper:ummmmmmm whaaa?
You could call it a scientific paper..
@Altrantis BIRD
This stands as one of my favourite videos to expose people to, especially since I'm currently studying atomic/quantum physics, and have finised my bachelor studies of astrophysics.
My hat is off to you, talented sir
I thought the expanding of the universe was the fastest "thing" recorded.
A4 is an amazing measurement to accurately scale the distance of stars, planets, moons, asteroids and everything else.
I feel amazing and am brought to tears at this marvelous measure of magnitude. Truthfully, it is so very awe inspiring that we live in a complex yet empty still universe and to glimpse into the perfection of it all with such clever mundane way should most certainly be recognized as a joy.
Came for cool paper facts.
Left with existential dread.
so true
:)
@Edvards Auziņš now that's just false yes in the grand scheme of things we don't matter but we can help make ourselves matter and be happy cause there are no do overs as far as we're aware
@Some guy named Zwie if I live only once and I get to experience things only once, then I want to experience the nothingness of life/existence throughout it.
YET DREAD IS YOUR LOT
Exactly.
Man, what an innocent video about Metric Paper! I sure hope this does not turn out to be existential!
Ahh yes... I remember when I would cover the universe with paper or making a paper so small I can't even touch it.
I never thought of things like communication between satillites and servers er whatnot to be flashes of light. it would be sorta cool to see that in a different spectrum how a satillite shoots beams of might at earth
From micro to macro isn't life just fascinating enough to describe with just a typical metric sheet of paper?
If you didnt have an existential crisis in the first half, don't worry, CgpGrey got you in the second half
And the overall existential crisis is the same ratio as its constituents!
i just was like 'wow we are made of quantum pixels, that is heavily trippy'
None got me mr non mathematical genius
I didn’t have an existential crisis ever in the video
@Grab the Crucifix Band damn dude i don’t care
Simple concept, beautiful execution, great job, grey
this man basically just explained what a perfectly shaped piece of paper could grow into
I love this, but you could have listed it as A1028 instead if A4/2^10 and so on. :D The paper transcends all.
I like how all reality is printed on A232 paper, therefore.
Excellent! A (micro/macro)-cosmic view of the Universe. Classically and wonderfully done.
Grey 10 years ago: "So this is why we should get rid of pennies"
Grey now: "After studying a sheet of paper, I've been reminded that everything is nothing, everything we've ever known and loved is all foggy shapes in the ethereal."
Until you realize that there is stuff in the nothingness
@Windows XP memes and stuff lol Yep "Nothing" is really just everything encoded within the quantum field oscillations the seething quantum vacuum fluctuations
"After studying a sheet of paper, I've been reminded that everything is"...
mostly nothing, and everything you've ever known and loved will die
I'd call it evolution!
I still think we should get rid of pennies, but now with a side of existential crisis.
Goes from talking about dimensions of paper and it's uses to contemplating life and understanding that our corpses will be strewn into atoms before some photons from the unobservable universe reaches us. Also, was anyone else strangely calmed by the plank length things?
I honestly got so sad watching this
Not mater what we do or what we achieve or discover
Nothing matters
We are just a speck on a infinitely big canvas
We’re just nothing
this is not where i thought this video would go. amazing and breathtaking. thank you.
I like how he now uses paper as a scale for when he zooms in or out
I mean you think it takes a second for light to reach the moon...
how can we be sure that it takes one second, or that one second... is even one second as you travel along that route, at whatever speed you are moving
@HoboGrifter he has a video about the metrics of all of youtube, I'm pretty sure he watches more than those two channels..
@DrabberFrog watch me ruin 333 likes on your comment
not as disgustingly perfect, but still cool nonetheless
@Max ???
@Max Yeah the space mice at it already
Beautifully made, great animation to reference the dimensions at least a little, you went quite deep there... .... i'll get my coat.
I was confused, angry, and upset when I moved to Canada from Australia and learned they didn't use the A sizing system for paper.
This just put a bizarre point into my head. Despite how insignificant we like to say we are in the grand scheme of the universe, by orders of magnitude, the Planck length is smaller to us than we are to the universe

Did you address how you butchered the math by saying that Mars is 14 light minutes away, when the sun is just 8 light minutes away?
