[QuarterLifeCrises]

Normal people: "hey A4 sheets fold in half and maintain the exact ratio. Cool!"
CGPGrey, having his fifth existential crisis this week: "Everything is mostly nothing."

[NintendoNerd]

“look at this sheet of paper”
*8 minutes later*
“we are now at the edge of the universe”

[thewatcher]

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."

[juancuelloespinosa]

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

[Moj]

"Hey Grey, look at this sheet of paper for a second."
Grey: (transcends reality)

[ChadrickNurn]

"I need a way of describing reality"
*looks down at blank paper*
"I've got it!"
-CGP Grey, overcoming writers block by embracing it

[botston]

Smallest metric: here is something that is actually nothing

The largest metric: here is nothing that is actually everything

[EmC]

Paper getting infinitely small: Has an existential crisis

Paper getting infinitely big: *Has an existential crisis*

[the-sands-of-time]

Normal people: "Hey, could you hand me a sheet of paper?"
CGP Grey: *​contemplates life, existence, and nothingness​*

[samueloconner]

I've seen many scale of the universe videos but never one that was filled with such a sense of cosmic horror

[The-Rest-of-Us]

I came here for light entertainment.

I left with an existential crisis.

[MCjossic]

What I liked most about this is that a) I learned that A0 paper exists, b) it is a satisfying, perfect 1m^2

[stormninjabros]

"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.

[lucystarlight]

I'm not sure what this video was supposed to teach me but I'll be more careful around paper from now on

[thonatmo]

If you didnt have an existential crisis in the first half, don't worry, CgpGrey got you in the second half

[chughes]

Love the re-use of "Illusion of something solid" at two completely different scales: A4 x 2^(-76) and 2^140

[Tay-ttgy]

Teacher: Okay, class, please take out your A4 sheets of paper and fold them in half.
CGP Grey: ...this A4 is a door... to the exponential spiral of everything...

[kpatch]

"What are you watching?"

"...mostly nothing."

[FetenWuWa]

Came for cool paper facts.


Left with existential dread.

This video makes me realize how much of a giant I am, bigger than so many things, but it makes me realize how tiny I am, and how earth is basically a quark inside an atom inside a grain of sand in a desert the size of a galaxy
