"Your theory of a donut-shaped universe is intriguing, Homer. I may have to steal it."
- Prof Stephen Hawking
I’ve heard that space is barren and lifeless, like a dessert.
We're in space so it can't be lifeless...
More so than a desert it has matter in it space is just empty more or less
Dessert
Nice!
I mean that's not a terrible way of viewing it.
"something less delicious, like a globe" - two words: donut holes 🙃😎
Caitlin: "Me neither!" made me snort-laugh!
Donuts... must be a childhood trauma of sorts...🍩 D'oh!
I think there’s a hole in this theory. Not all donuts have holes.
But there is in all toroids
So, the donut rings on core rope memory act as transformers. This suggests that the programs were more than meets the eye.
"A doughnut hole in the doughnuts hole. But we must look a little closer. And when we do, we see the doughnut hole has a hole in its center - it is not a doughnut hole at all but a smaller doughnut with its own hole. And our doughnut is not a hole at all!"

I now want a scarf with that computer code as the pattern ❤
i mean, that would be heavy as a scarf but i like the idea
My Dad was a programmer, and I remember him dealing with punch cards and Reel to Reel tape storage, when I was little. He was one of those who were top in their field.. I miss him.
I’m a programmer. But in 2022. Your dads an OG computer scientist, probably when it was still considered electrical engineering. Back then, to do this as a career had little immediate commercial value, so people did it for the challenge, to improve their understanding and technological capabilities. Allowing us to be where we are today, on UA-cam, thousands of miles away from each other, but engaging with each other nonetheless.
@@ImTHECarlos98 Another programmer here, I gotta second Carlos' statement. Dude was a pioneer. They had barely anything to work with, but were still able to make some incredible programs.
My dad still has some of those old punch cards in a storage box.
Hmmm bagels :3
Sucked.... Into.... A bageell.

"and the nobel prize in physics goes to the team that found the sprinkles of the universe right there on the glaze"
In computer graphics, a model that's more or less ubiquitous is called the "Utah Teapot". Martin Newell, who first used the teapot, chose it because it was easily recognizable as an every day object and had a number of features that made it useful for testing various rendering features. One of those features was that it has a genus of 1, making it a torus. When you mentioned the mug, that immediately came to mind.
For those curious, the other useful things about it are that it's rounded and it has multiple saddle points, which were useful for testing smoothing algorithms, it wasn't entirely convex and thus could cast shadows on itself, and was easily recognizable even without any applied materials.
"The Zen philosopher, Basho, once wrote, 'A flute with no holes, is not a flute. A donut with no hole, is a Danish." - Ty Webb
Pretty sure Homer Simpson came up with the donut shape universe
The distant light will reveal it’s actually a nacho platter.
Torus - the shape a Civilization map takes on if you let it loop top to bottom AND left to right.
Would this imply that a donut universe won’t have a heat death? Since it might all…be going back around? Would parts of the background radiation be..reheating as it loops? So crazy. I’m kinda bummed this stuff was part of my curriculum way back when.
Universe is just amazing!! 🤩
Magnetic fields also tend to have toroid shapes
As Adams wrote: "[the] whole fabric of the space-time continuum is not merely curved, it is in fact totally bent. "
I heard that Dunkin Donuts kicked people out of their shops if they refuse to acknowledge that the Earth is shaped like a donut.
"I hate the universe!!"
-Yngwie Malmsteen
*Laws* of physics?
Donuts?
I see a connection
And the multiverse is an "Everything Bagel"
Doughnuts versus Doughnut holes!!
Larry Niven wrote a SF called "The Integral Trees" that takes place in a toroidal ring of atmosphere around a neutron star that is inhabitable. For a planet to be toroidal I would wonder what kind of tidal effects would be there. I would assume that it could never coalesce as tidal effects would overcome any gravitational collapse and adhesion of rocks into a planet. Even Larry Niven's Gas toroid would not be stable in any time stellar frame.
Donut Earth! The flat-earthers will love it! Nom nom! 🍩
Physics likes sprinkles more than cream/jelly filled, glazed, or chocolate.
Shoot, why not just add another dimension to get a klein bottle shaped universe?
my universe is a maple bacon donut.
Tearing it a new one... 😂
Mmm space donuts
The thought of the universe being a donut makes me feel strangely claustrophobic, and space in general gives me agoraphobia. I should probably just accept the fact that I'm an earthling who's not meant to know anything about what's going on outside of earth.
so science fiction idea.
we develop faster than light space travel. we learn the universe is a 3Torus. We find another planet with life...but it's us. we just don't know it. We attack it, thus destroy ourselves while simultaneously attacking and defending
Sounds very interesting.. would love to read/watch something like that.
dude what i need that now omg
The donut shape universe can explain Dark Energy with pure gravity
Elaborate?
Lol
@@WestOfEarth I'm not a cosmological topology expert, but imagine the center of mass of a donut (AKA torus). The center of mass is exactly at the hole. Now imagine everything (on the surface) moving towards the center. Any galaxy at such surface will "see" all galaxies getting away from it (at least at the outer surface). AKA Dark Energy explained with gravity due to the Torus topology.
Now, since Lambda (dark energy) measurements have not yet being conclusive and cosmologists believe we live in a flat universe we can rule the donut out. However, if we find a negative curvature, I believe that Dark Energy won't be any more a problem.

8:59 if the moon were elongated it would even be funnier and more interesting
Homer- MMMMM Donuts.
Bagel. An everything bagel.
#EverythingEverywhereAllAtOnce
you know who else likes donuts?
D'oh!
No mention of Larry Niven's Ringworld?
My tl;dr "Sigil might actually exist somewhere out there."
Same reason the like sphere
I made a joke last year that the earth was a donut shape in response to a flat Earth comment and your telling me a donut shaped planet could really exist?
The universe is clearly an everything donut.
So is a person a donut?
yes
@@johnmcgimpsey1825 people have multiple holes. not 1.
Woah~ this video is thought provoking! Take that FLAT EARTHERS~ we now had new theory😂TORUS EARTH🤣
I like donuts
Hmmm donuts.
Where is Andrew Price? He need to see this here
Homer Simpson (give or take a crayon in the brain) would approve.
Donuts
Doznuts
Deznuts
Deeznuts
Deez nuts
Because the universe is sentient, and its name is Homer Simpson. 🤓
DOH!!!! 😆
mmmmmm donuts!
Regarding the asterisk at 3:38: I generally see "curvature in space-time" as indicating warping by gravitational fields. But in the laser example, the lasers should eventually diverge because of dark energy. Is that also "curvature in space-time" or is that just somehow discounted in the "flatness" assessment?
Mmm, cosmic doughnut. 😋
If the universe is expanding wouldn't that mean that the laser beams would have to get farther apart? Of course the sources would be getting farther apart as well keeping them parallel. I think I just broke my brain.
..... wait we're playing pacman?
Anyone else going shopping for an infinite light box?
Donut shapes are a torus are rather unique. They are a single circle with volume. If they are as big as the Universe then they are not a ball, they have lines of travel that are more easily captured and defined. Measurement is prime when we measure space and time. Is the 5th dimension not a pop music group? 3 + time = 4. The next dimension is needed to explain the Universe.
Spank the Hank~
LOL memory. Just like my brain. pure of lulz, bunch of holes.
Could it be that gravitational lensing explains the three torus law?
Toroids, Sweetie.
Bruh I’m sitting here hitting my weed pen and the dude who turned the 3d universe we see into a donut blew me away!!!
I donut understand why there are so many donuts
I don't believe a cup and a donut is the same thing. Obviously you can't eat it and drink from it in the same time.
It can if you drink it faster than you eat it..... proof of concept done on multiple bread bowls at Panera. Lol.
Once again, a compilation just reminds me how much better this channel used to look.
Yep...pretty sad tbh.
Note to self: watch again sometime.
Flat Earthers couldn't be more glad for this video
Ringworld
The people pushing for a donut univers sound like desperate finitists. You were forced to compromise in the "smallest" unit and put in "meaningful" because use use a contimum for everything for measurements. Sure a plank is the smallest "meaningful" unit but that doesn't mean there isn't instances distances smaller than a plank just that all the forces are larger than those measures. The problem if you don't permit smaller measures is that physics would break down with the conservation of momentum. For example, a video game that failed to measure diagonal distance correctly using a 2d array ends up slowing down or speeding up because of the square root of 2. You solve this by using smaller numbers to imitate real numbers, or you create a hidden variable that tracks the miscalculation to fix it when the error becomes large enough to matter. Both solutions have Infinite precision and mess with finitists deranged ideal. You can't put an actual continuum on a 2d grid. It only works if the 3D grid is finite with no distances between distances. Its like the difference between the number of Integers and the number of Real Numbers.
Really not a fan of preassuming embeddings of manifolds into higher spacial dimensions. You don't really need 4D space to have a 3D manifold. That's just us putting our naive expectations based on only perceiving surfaces that are embedded into our space.
LOL memory
But.. dude.. ok, just.. hear me out. What if, right... what if.. it's, like..
...A bagel!
Riiiight?
* bubbling bong sounds *
Right?
We can't say if it's flat. It might just be big AND curved. Flat-Earthers and all that, don't be a Flat-Universer
life start inside a donut the moment after a big bang HEHEHEHEHEHHEEHEHE
Because god is Homer Simpson.
Did you know that it takes 7 colors to color any map on a torus so that no two adjacent regions have the same color? Did you know that on a sphere it only takes 4 colors? Did you care? Did you care that you didn't care? .... :)
Physics. Broca's area, or the Broca area is a region in the frontal lobe of the dominant hemisphere, usually the left, of the brain with functions linked to speech production.
Savannah is a better host than Hank! She speaks as clearly, uses inflection wonderfully, and talks faster than Hank does. Yay Savannah!
The expression of all these fundamental forces in whatever way they ultimately form in our 3D world would be the most stable shape, a circle. Here and probably every other multiverse. Are circles the most predictable thing in all of space time? Including every other universe.
I think the more important question is... "Why donuts?"
Why is that shape found in multiple places.
I of course KNOW why... Because I have a big brain IQ.
I want to know of YOU know!
😀😂
a coffee cup has 2 holes.
Nope. That’s not how topology works.
ᴘʀᴏᴍᴏsᴍ
How does this not boarder on theology? Maybe our perception of the universe is limited by our ability to comprehend as humans.
Maybe
Possibly
I don't beelive in the univers
Physics doen't love donuts. It's donuts who love physics. Physics was prior to donuts.
Infinity has no boundaries, therefore it has no shape. It's just my hypothesis thinking in terms beyond mammal brains. Everything in a mammal's experience is limited by limits and scarcity. Try not thinking like a mammal.
Ha ha ha!
Under the most resent defined definition of a planet is it must be spherical under it's own gravity and it's orbital path must be cleared. So, THERE ARE NO DOUNUT SHAPED PLANETS. And it is spelled Dou - nut not Do - nut.
It's not "dounut" it's technically "doughnut" but the more colloquial spelling, "donut" is widely accepted and used. Also, since we're on the topic of spelling and grammar, you used the wrong word in your first sentence. You put "resent" instead of "recent."
@@Jerekul or is that Jerek*** Blame spelll chek eye wasn't watching and your widely accepted Dooo - nut can take a moldy leap
@@jondilinger8639 You're obviously not using spell check since you didn't even spell that correctly either 😂 "spelll chek"
@@Jerekul I guess some people just don't get it. It was done on purpose. You don't get satire, do you?
@@jondilinger8639 lol, I do get satire, it's just that it can become difficult distinguishing it, especially when it just appears as further ignorance within the context of the previous comments. But now that you point it out, yes, that one sentence does appear satirical specifically with your spelling of "eye."
