Sorry I messed up the seeds at ~6:00 lol, check chat for the real seed.

3:24 "Infinite Mineshaft" now that's maybe why I spend 5 hours exploring a mineshaft

Me, an intellectual: **opens superflat world**

3:22 "Yeah hold on I need to loot this mineshaft and then I'll come back up"

Can we talk about why he has a world named “are villagers antisocial?”

"Minecraft worlds can`t be the same.. or can they?" *Vsauce intensified*

I find it beautiful that you can share the same chunk with someone you don't know, possibly on the other side of the world.

Imagine just exploring the mineshaft and you really want to explore all of it and you go all the way to the world border

The Unsolved Mystery why Wifies only has 100k

This video induces slight anxiety in those that actually know how Java Random works

When he mentioned the pigeon hole thrown he was close. The problem was he focused on chunks rather than what generates chunks. Chunks are determined by the seed of the world, Minecraft works by hashing your seed, there's an "infinite" number of things you can input for a seed but they all get converted into a specific number using this hash function. Because there's an infinite domain and a finite range this leads to multiples of the same input mapping to the same hashed value, this is what's known as a hash collision.

imagine trying to explore a mineshaft and not knowing that it’s infinite

“Both seeds converted to binary are the same but just a couple of 0s swapped in” bruh it’s binary you can say that about most numbers

Nobody: Wifies in 2069: how many eggs in every server are there on minecraft

The last four digits of the seed, in Decimal, are responsible for structure gen. As long as you keep those last four digits the same, you will always have the same structure gen. This is something that has been known by the Minecraft Set Seed community for quite some time.

I love how at 0:06 he has two worlds named “The sponge you shower with” and “Are villagers antisocial”

420vapemaster69 WHAT A NAME!

Turned himself into a Minecraft Vsause, coolest shit I've even seen.

so, i remember before 10 years i was watching a mc youtuber who had just started a new world, o month later i started a game WITH THE EXACT CHUNKS as his. Same biomes, some villages etc.

Me seeing this video with 1 minute before class: Also me: Yeah, I've got time.

Wifies: some seeds have copies Antvenom: *I am four parallel universes ahead of you*

imagine if some seeds could be altered by mojang, that would be so cool. imagine a seed that has "Sub to Wifies" just built at spawn

Ok, so I go into a world to speedrun, right? I see a ruined portal and a village, loot the village, go into the portal, then explore and found another ruined portal in the nether with the exact same loot as the overworld one. Just thought this was weird

Wifies: **Spitting numbers** Me: I didn't get a word of that.

6:45 "Its basically the same thing, but with zeros swapped out for the ones" That's binary there's only zeros and ones.

nobody gonna talk about how the skywars footage was recorded two months ago

0:30 I actually has that seed as one of my hardcore world once I still remember that spawn point

The vsauce music, the “or is it”. This is a masterpiece. You’re definitely Michael, or are you? *vsauce music plays

...I can't be the only one that laughed at the calculator saying infinity for five mins straight, right?

Can we all appreciate the rare tall birch forest in the intro while he was showing the terrain for a moment?

I remeber that in the old times, when putting a seed, if you out alot of "0" you get infinite mountains and ravines too

"Now I dont know that much about world generation-" **proceeds to explain in depth how it works**

The entire part of can there be the same chunk in the same chunk on two different seeds is always a yes. It is called sister seeds that share all the same loot and structures (and biome(s) to a %). For every world you make there are 2^16 -1 other seeds just like that one (that's 65535 seeds). Sisters are used a lot when finding the perfect seed for speedrunning. The same chunk in different coords is interesting and currently unknown. Also just as a note: sister seed is not a shadow seed, they are 2 completely different things.

so the last few numbers or so of a seed when converted into binary are what define the structures, the former characters are what define the biomes and what not, so if you add 2^16 to a seed, you'll get a "sister" seed, they have the same structure generations but different biomes. this strategy was used in the 1.8.9 SSG speedrun to find the most optimal seed for the run.

I really love watching your videos, and one of the reasons is you making the effort of doing your own research and calculations. It's not really common to see gaming youtubers using their own calculations as backup to their theories and as further and clear explanation of how the game system genuinely works. It's good to see someone who can start from pure facts and build something strong only from them. Your reasonings are just pleasant to hear, even though I may struggle to understand english, especially fast-spoken, sometimes ! Keep up the good work !

You could literally have an identical seed except for 1 chunk because all worlds are infinite. Video is also super cool, I appreciate all the effort you put in!

I'm actually strangely knowledgeable in the area of infinite terrain generation, although the jargon in IT is "progressive terrain generation" since it's not actually infinite, it just progresses as the player progresses. Although I don't know exactly how Minecraft does their progressive terrain, there is some technical knowledge I can supply, and hopefully I'll be able to help solve the mystery shown at 6:00. For starters, the surface of the world is generated using a type of visual noise known as "Perlin Noise", used to generate visual black-and-white noise that transitions smoothly between minimum and maximum values. This noise script is added onto itself as many times as the developers choose to generate Fractal Noise, to give smaller details on top of the larger shape. However, this type of script has one fatal flaw, being that every single instance of Perlin Noise is identical; you can't have random Perlin Noise. So, what developers do to get around this is they randomise where the Perlin Noise is initially sampled from, and these values are so high that it might as well be random Perlin Noise. When it comes to fractal noise, each layer of Perlin Noise (aka each octave of Perlin Noise) is sampled individually from the other layers, allowing each layer to be sampled from entirely different locations, providing more randomness to the terrain. The easiest way to accomplish this is to just put the world-seed into a random-number generator to spit out an x-offset and y-offset for each layer of Perlin Noise. Then, to turn the shape of the fractal noise into an actual 3D surface, each value within the perlin noise is interpreted by Minecraft's code as a value between 0 and 255, with interpretations being different depending on the biome the values are being interpreted in. Now, with all of this knowledge presented, I'm going to show you why these two worlds were completely identical at these specific coordinates and why there are probably many more coordinates in these worlds that are identical, and it has to do with the way that random number generators actually work. For starters, there is no such thing as a "random number generator". They're actually "pseudo-random number generators", with "pseudo-random" meaning "fake random". While I won't go into detail on how they work, RNG is nothing more than basic mathematics with really large numbers outputting relatively small numbers, to make the outputs look random. Which means the same input for an RNG script will give the same output. The other thing to know about RNG is that each output it generates will always become the input the next time it's called, unless the code changes the input directly. It is very possible that two numbers, when put into the same random-number generator, will output the same number. And, since that output becomes the next input, the second, third, fourth, fifth, and every other number that is generated by that random number generator will be identical, until the input is directly changed by the code. If you were paying attention earlier, you might be able to piece this mystery together now. Like I said before, the sampling of Perlin Noise is offset randomly using a random-number generator, where the world-seed is the initial input. So, what has happened here is that these two seeds, when put through the random-number generator, outputted exactly the same result for the first time it was called, meaning every other time this random-number generator was called outputted the same numbers for both seeds, giving both of the worlds exactly the same Fractal Noise. That's why they were identical when you got to those coordinates. Which then raises the question as to why it was only at these coordinates that the worlds were identical, but if you were paying attention earlier you'd probably know that too, and it has to do with the biomes. Like I mentioned earlier, each biome interprets the fractal noise differently, so that the surfaces of different biomes generate differently to each-other. I have no clue as to how Minecraft's biome-distribution works (although I'm beginning research on biome distribution shortly), but what's happened is these biomes just so happened to be identical at these coordinates. And, since the fractal noise for both worlds are identical, and the biomes at this location is identical, the surface for both worlds were generated identically at this location. The ores, grass, caves, trees and ruined portals, are probably also generated with a similar process using RNG, which is why these were also identical at these location. Theoretically, so long as the biomes for both worlds are identical at a certain locations, there could be so many more locations within these worlds that are identical. I'd suggest going to the ChunkBase Biome Finder and trying to find some coordinates where the biomes in each world are identical. I just found a point at X -6378, Z -12297 if someone wants to give that a go.

This really isn't even remotely unsolved, and we know exactly why all of these anomalies happen. It's just that the explanation is so technical and requires so much understanding of computer science that very, very few people truly understand enough to explain it in detail.

You’ve gotta be my favorite MC YT’er, every other Yt’er always sounds cringy, like a child, and never fully gets to the point directly. I appreciate your videos. EZ Sub

Dude! I thought I was a savant because of some of my ridiculous builds, but you have to be a savant because of the things you are able to work out! Respect!

Theory: Every world is connected with eachother.

Dream and Wifies should collab and do a Unsolved Minecraft to start off season 2 Episode 2 in style.

Just wait till they find that one iron ore block out of place..

Good job buddy! Really appreciate all your hard work.

There's Vsauce music in the backround. Wifies is mutating.

0:35 Hello vsauce wifis here!

Great analysis! Thanks for uploading!

so I recently learned this from one of the videos I came across with. The specific binaries you've pointed out that are similar are what affects those generations for the ruined portals and such so it's high likely there are multiple other seeds with the same location generation regardless of the biome due to the difference in the first few binaries.

In 0.7 pocket edition its actually the same seed just different location

Those seeds at around 5:30 aren't different completely, they have the same remainder when divided by 2^48, which due to some technical reasons related to java is what matters for structure generation

Wow I respect u cause u did so much research for this. Earned a sub

The seed: *I can't think of a type of world generation style on this chunk. Maybe I'll just copy the others.*

”Unsolved mystery” haven’t seen that title for a long time

"Same World, Different Seed" People who discovered the world in the title screen in Minecraft: **chuckles** I'm in danger

5:24 The fact that there was a spawner under the ruined portal is just... Incredible

3:55 that mineshaft was really weird, imagine loading up a new world and traversing that shaft for eons

He became Vsause the second that music started.

I appreciate the Attorney Ace noteblock music you put when you make a plot twist.

incredible video, as always !

Antvenom has a video on "shadow" seeds, witch might be fenómeno you're experiencing here

I used to rule the world Chunks would load when I gave the word Now every night I go stow away Hide from the mobs I used to slay They once were terrified Every time I looked into their eyes Villagers would cheer my way For a hero I was, that's what they'd say One minute we had it all Next our world began to fall Away from all that it had once become They all cried for my help, but I stood there numb I gaze off into the boundless skyline Noteblock choirs playing in the sunshine Turn 'round pick up my sword and wield The blade that once forced evil mobs to yield And hope one day that this chaos and Destruction turns for the better Never a bow in hand That was when I ruled the land It was the creepers and Skeletons Blew down the doors and boxed us in Arrows whizzing by like streaks of light I tried all that I could to stay and fight As the undead roamed the street Families broken at my feet Life itself suspended by a thread Oh, why is it that I wasn't dead I gaze off into the boundless skyline Noteblock choirs playing in the sunshine Turn 'round pick up my sword and wield The blade that once forced evil mobs to yield If this battle should leave me slain I know Herobrine will call my name Better to take a stand That was when I ruled the land I gaze off into the boundless skyline Noteblock choirs playing in the sunshine Turn 'round pick up my sword and wield The blade that once forced evil mobs to yield If this battle should leave me slain I know Herobrine will call my name Better to take a stand That was when I ruled the land

15:22 SUPER MATH TIME STARTS

This is also the same reason that if the universe is infinitely large there’s an infinite number of you doing an infinite number of things and an infinite number of you doing the exact same thing as you

14:33 This dude is literally beating a Hacker, that dude can't be legit

5:00 this happend to me once in a creative and surivial world and I just thought WTF I HAVE SEEN THIS BEFORE, sadly it was so long ago, I do not remember the seeds

I could listen to KZfaqrs doing math all day, as long as I DON'T have to do it.

whats funny is terrain generation is separate from cave generation, so theoretically you can get worlds that have different caves and the same terrain or the opposite.

The ace atoury music is really the cherry on top for this vid!

0:37 lmao you sound like vsauce 1:55 LITERALLY using vsauce music lolol

Since when did you hit 120K?! Congrats!

13:43 that is very fast... must've taken you a lot of tries... good work... i appreciate it... :D

I'm brazilian and I was hearing him okey. But when he started talking fast at 13:50, I give up because I didn't understand anything he said, and I'm sad

Yes, in the end dimension there are plenty of identical chunks

And in conclusion, there are a lot of pigeons.

Bro this channel is noice I always learn something new when watching

This reminds me of the shadow worlds of Minecraft, worlds that generate biomes in the same place/cords but everything else is different, makes you think about how random isn’t really random.

i could have sworn your skywars background gameplay was in another video of yours... at 3:49 Edit : AHA! ive found it! its in “V O I D L A D D E R”!

Who's this Wifies kid and why did I sub at 1k? Ok well I guess I'll watch some more. love the vids man keep up the great work :D

can we just take a moment to appreciate that he makes everyones quarantine 100 times better

"360 to the 51200 powered returned infinity on the calculator, which is a wee over 14 trillion so I think we're out of luck" These little snipets of comedy said really seriously in otherwise serious videos, they always kills me

0:37 vsauce music starts playing

Plains and ocean chunks in particular seem like great candidates for duplication. They don't generate emeralds or trees and have very predictable surface heights.

13:46 "Dear Notch, Hi ! It's me ! Austin !"

Really appreciated this video thanks

am i the only person that doesn't understand a SINGLE thing said in this video?

2:00 64 snowballs That’s illegal

This comment is just to help this guy climb on the yt algorithm.

I remember running into basically my first world seed on the old Xbox 360 version. It was really interesting. I found the exact same mountain I made my first house on with the exception that it wasn’t a snowy biome, which when I first came across it in my first world, it was.

"we have no idea why the duplication happens in the first place" - you displayed a forum post, ON THE VIDEO, that tells you why!

“Are villagers antisocial” *mood*

Fact that people often forget, infinite does not mean that something won't happen twice, they say earth is one of a kind.. it isn't. The universe probably has others. Just like our favorite blue marble, Have fun trying to have a goodnight sleep now.

I started a minecraft world a few weeks ago with my dad, and I was flying around with my elytra, when I stumbled across a landscape that looked strangely familiar to one of my other singleplayer worlds. There was the same big tree in a plains next to a mountain. I might try and go back there somehow and investigate because in my singleplayer world there was a cave with a zombie spawner in it. I kind of just looked at my screen weird for a moment before brushing it off and thinking it was nothing.

In theory if something is infinite there will be an infinite number of things that are the same except for a slight single change. Technically if Minecraft worlds were truly infinite there would be an infinite amount of world the same except one block off

42 views and 64 likes, of course that makes sense

Think of the worlds as two graphs, randomly intersecting...

i have a theory it's been like a week ago I saw a video which says that when you open a minecraft world it is 3million by 3 million blocks from your spawn point . so if you teleport 3million blocks away from you spawn you'll actually find the border .But which confuses me a lil' bit is that there is still infinite chunks after the border , which means that the worlds are probably one world but the seed controls your spawn point in that infinite world and also the border that is 3million blocks away from the block you spawn on. hope this helps😀😊

omg not only is wifies entertaining and awesome at Minecraft, he’s also extremely smart

16:07 look at the background footage! lolol

“This Minecraft world is identical to a world you’ve already seen” is where I got spooked a bit because yes, that was, quite literally, a world that looked pretty much identical to one that I have loaded up on my own computer

I'm no expert, but maybe the two identical chunks have something to do with 9223372036854775807 being the 64-bit integer limit?
