Can you think of a bigger number than this?!

- In 2007, a legendary battle occurred between two philosophers, Augustin Rayo and Adam Elga, where a new number was created. A number so large that if any human could truly imagine it's size, their head would immediately transform into a vast black hole (I am not kidding).
Rayo's number breaks the limitations of mathematical functions and even the English language to create something truly unfathomable! Even the Busy Beaver function stands NO CHANCE against Rayo's number!
In my last big number video, a lot of people beat my biggest number but I guarantee that no one will be able to give me a number as big and as well defined as Rayo's number!
Good luck!

Corrections: 11!!!!! is 5 single factorials iterated, not double factorials;
BB(n) usually refers instead to the number of steps until halting; the maximum _total_ number of 1s (consecutive or not) is known as Σ(n). Recently, Σ(6) has been found to be far larger than 10^10500 -- in fact, it is tetrational level.
Also, nice to see the bounds on Rayo function being presented here lol, in fact in the large numbers community I was the first to suggest bounding explicit values for Rayo, although I did not participate much in the process. The first bounds were pretty bad, at around Rayo(1000) > 65536.

amazing! thank you for answering my request. The visuals make everything easier to understand, I applaud your efforts, sir!
It's SO interesting that the result of BB(4) can be counted on hand while BB(5) is astronomical even for computers!
Anytime! If you have any other requests, feel free to voice them 👍
The Busy Beaver function is probably my favorite! If you look into it a bit deeper, you see that the reason computers can't find a value is because there is an astronomical amount of different instruction card combinations, and for each combination, you can't stop the beaver until you know it has finished or if it looping. This is hard because there are cyclic patterns that make it look like the beavers' movements are looping, but they aren't.
It's an amazing computer function and crazy to think about with googol Instruction cards!
Very interesting indeed. The busy beaver function is actually uncomputable, though! Meaning that you cannot compute the value of BB(x) for any x with one program, even with infinite time. This is because turing machines are equivalent to our computers, and so you could imagine a contradiction similar to Berry's Paradox if you could compute the value of BB(x) with one program.
Say, if you have the amount of states that you need to construct that turing-machine as x, you could make an x+y+1 (for some relatively small y) state turing machine which will start with every cell of the tape at zero, use y (here you can imagine why y would be relatively small: if it wasn't, BB would be slow growing!) states to set up the number x+y+2 (encoded into whatever encoding for numbers the x-state turing machine for computing BB uses), then x states for the BB program, and finally that one extra state to move right until it finds a zero, and then set that zero to one (if it's state z, then this would be 1->11z, 0->110) to increase the number. This would give us BB(x+y+1) > BB(x+y+2), which is impossible. This argument is slightly handwavy, but there is a very closely related problem known as the halting-problem with formal proofs.
Please note that this is different from one program existing which computes the value of BB(x) for some fixed x, which obviously exists: it's just the winner of BB(x).
Now... how was BB(4) computed? (and how is BB(5) currently being computed?)
Programmers can write "deciders" which will take a turing machine as input, and either say that it definitively doesn't halt or that it doesn't know whether the machine halts or not. Now we just have to make deciders which are strong enough to decide every four or five state turing machine, and then run the ones that it doesn't know about until the machine halts. Practically, you can't really know whether the decider is strong enough, so you just have to run the turing machines until a stronger decider comes along that says it doesn't halt.
Currently, a large project focused on this is bbchallenge (at bbchallenge.org)
@eig5203 very interesting. For BB(1), there are only 64 different cards to analyze, so surely this is computable??? Couldn't you do this with a pen and paper ?
@@jazlearn5147 Yes, that is essentially running a decider yourself instead of using computers. Once you get into something like BB(800) (I believe the current lower bound is BB(748)), then there aren't any deciders which will provably (in ZFC) work for all turing machines of that size. Eventually, every (recursively-enumerable) axiom system will run into this problem.
BB(5) is probably just 4098. BB(4) = 13 isn't as easy as counting. it was actually really hard to prove that every turing machine with 4 states which took longer than 13 steps to terminate, didn't terminate at all. same with BB(5)
I'm curious to know why you chose to describe Rayo's first comeback to be ((11!!)!!)! when using five single factorials would have been much, much larger. Do you have a source that implies Rayo definitely intended the string of characters to refer to double factorials as opposed to single factorials? For example, you show that 11!! Is equal to 10395. But 11! (Single factorials) is equal to 39,916,800 all on its own! Is there a convention that says all two factorial marks together are assumed to be double factorials? If so, was that a convention that Rayo would have followed? Great video, covers these topics clearly without needing any deep mathematical understanding.
Yea. At first I did that because I was using Wolfram Alpha as my source, which told me to do it like that. But then I realized it was an ai source and thus did not fully understand what I was doing 😆 so I looked at single factorial values and the numbers would have gone off the screen real quick (because they are so big!), so I just decided to introduce double factorials for fun while keeping the numbers on the screen lol 😆
Fair enough. I tried doing my own back of the napkin math using Sterling's approximation to find the value for single factorials and the resulting power tower is a nightmare to try and simplify. Thanks for the clarification! As a very, very handwaved simplification of the real value, I got the tetration of 10 to 6, or 10⬆️⬆️6 using up arrow notation.
@connerwinder2218 Thank you! 👍 😊

Thinking back to another video I watched, considering they said you can put any number into the TREE function, we can always have "TREE(TREE(...TREE(Rayo(10^100)...)" but in order for that to be the largest number it has to at least be proven finite.
The same can most likely be said for the Rayo function as well, there is no limit to how big a number you can put in there so long as said number is finite; it will still come nowhere near close to the smallest form of infinity (Countably infinite). And then we have to explain to the kids why infinity is not a number and just means something that continues on without bounds...
TREE is finite for all finite inputs, so that is indeed finite.
And of course the same thing can likely be done with the Rayo function by stacking its own function within itself (i.e."Rayo(Rayo(Rayo...)")@@hyperpsych6483
We know TREE(n) is always well-defined (finite) because of Kruskal's tree theorem. Kruskal is basically the reason any of us are ever even talking about TREE(3) in the first place.

Is that actually how it works? I looked at a lot of sources, and it said the way I did it was right. Your way makes more sense, tho 😆 you are probably right. Thanks for the knowledge!
@@jazlearn5147 The number of exclamation marks is the number subtracted for each multiplication. Five exclamation marks means that the multiplication is 11×(11-5)×(11-5-5)...etc. As it happens this stops neatly at 1. In other cases, we would stop before things go to zero or below. The keyword here is "multifactorial", and Wikipedia has some information about it if you're interested.
Interpreting more than two exclamation marks as a combination of double and single factorials is what the WolframAlpha website does - which might be what you used(?) - because it hasn't been programmed for triple etc. for some reason.
It's not entirely certain, but in context I think the 11!!!!! on the blackboard during the competition was intended to be ((((11!)!)!)!)!. Stacking single factorials like that gives the largest possible result. There's also that 66 would have been a losing move.
I always assumed it meant ((((11!)!)!)!)! And since 66 < 1111111, I'm sure so did they. Just shows the importance of defining your functions if you're using them in an obscure way rather than assuming everyone is on the same page.
@19t2000 Yes, I believe you are correct in that assumption. I made a mistake.

The factorial of any natural number N is equal to all of the natural numbers from 1 to N multiplied. 11 Double Factorial, that is, the Factorial of the Factorial of 11 is MUCH LARGER than 10395.

Rayo starts by writing a 1. Then Elga writes down as many 9's as he can fit on the board. Rayo counters by writing as many 1's as he can fit on the board, which resulted in a much larger number, because he could fit way more digits of 1 on the board than Elga's 9's. Then Elga changes all except the first two 1's to factorials, clearly resulting in a bigger number.

@@melooone when you write many factorials, the sources I looked at said they become double factorials. As for the other slight inaccuracies, I did that for the video sake. Didn't want it to be too long. It was more to introduce the numbers, not so much to be historically accurate.

Appreciate YOU! 😁 💛
So, the thing about this is that Rayo's number is not truly calculable, you would have to go through literally every iteration of the google characters to find it. In some cases it wouldn't even be considered a number, but many say it is without realizing that there is no direct formula to the value.
sure it's nearly impossible to say anything about it but so is tree(1000) using your logic and most people would say is a number even though people can barely say anything about it so it is a number just a completely useless number
Uh, so is many other "large numbers" (even, say, TREE(3)). We have no way to even find their last digits, let alone first digits, but they are considered numbers. Also, someone has made a 7901 character Rayo script which exceeds BB(2^65536-1).
So it is computable. You found a way to compute is. True, doing so in the real world is a tad impractical due to the amount of computer time required - but that's a small matter. It's finite, it's computable, it's just big.

me: just add 1
Since I have no sense of how big that is: I will explain what I think of as the biggest number. It uses tetration, but even further along. The number idea was basically a googleplex to the tridecation of a googleplex. tridecation is basically exponentation, execpt instead of multiplying the base the amount of times specified, you do that many of the base to the dodecation of eachother. Dodectation is pretty much the same. I would label them 13 (tridecation) and 12 (dodecation). If you label them as 13 and 12, exponentation is 3. (Multiplication is 2 and additon is 1)
Well, now imagine that, PLUS ONE
What you described is not even a quark compared to rayo's number, or even to far smaller numbers such as Graham's number and TREE(3).
Check out Knuth's up arrow notation. What you've described is a Googolplex (11 up-arrows) 2. Also using a googlgolplex becomes unnecessary, just use 3's instead and add 2 more up arrows to ensure it's larger.

But Rayo's number just arbitrarily picks "a googol" as the "Rayo function's" input.
Graham's number isn't arbitrary because it was used in a proof. Tree(3) is a little arbitrary but using 3 as the input to describe this number is done because of how amazing it is that it exceeds Tree(2) by so much. Obviously Tree(4) is bigger still, but that doesn't "feel" as amazing to me.
But Rayo just picked a googol out of nowhere. I can easily beat that number with a bigger input. Rayo(Tree(googol)), for example. Rayo himself could have picked that input instead-he just...decided not to. His idea of a function was brilliant, but his choice of input doesn't "feel" interesting to me like Graham's number or Tree(3).
Well, too late. You can't add a bigger input because that would be breaking the rules, also get it "GOOGOLogy". fitting for the largest accepted number

Thank you! 😊
I'm still waiting for a video that explains HOW we know one huge number is bigger than another huge number. I know (because I've been told) that Rayo's number is bigger than Graham's number, and Tree (3) is bigger than Graham's number, but how do mathematicians prove this?
a guy called harvey friedman wrote a proof of this statement in 2000
On the fast growing hierarchy (FGH), Graham's number (or sequence) is equivalent to the function of ordinal omega or omega+1 (where 0 = successor/counting function, 1 = addition, 2 = multiplication, 3 = tetration......with infinity = "omega function", the next "strongest" function being omega+1) Graham's number sits between this level of function and the previous level, that is, its growth rate is 'omega', or faster than anything that can be described through any lower function (for example, you can't express graham's number as an exponent, or even as a tetration, or anything really less than its explained growth.
Eventually, after 1, 2, 3,..........infinity (omega), omega+1, omega+2, you get to omega times omega, then omega times omega times omega, etc. The whole time these are describing insanely fastly growing functions. In the end, there's some ridiculous ordinal called the Rieman Zeta ordinal or something like that, describing some ridiculously fast growing function.
The rate of growth of TREE(3) is higher than the Zeta ordinal.
However, I've still been able to explain the "strength" or growth rate of these numbers using just the English alphabet and a few symbols (numbers, brackets, equals signs, etc.), let's say 50 symbols at most right? Rayo's Number denotes a number that is so large that you need at least 1 googol symbols to explain it (rather than the 50 I'm using right now).
I'll look into that. I'm guessing it'll be very complicated mathematics, but I'll see 👍
@@jazlearn5147 The youtube channel numberphile explains it well, check oiut their extra footage video on TREE(3)
Definitely very interesting, but slightly complicated (especially for TREE). I would suggest that you look into (transfinite) ordinals for now.
Once you've learned about that, the reason that TREE(3) is so big is that it essentially implements a structure that acts like ordinals for the trees, where "less than" is essentially "is embeddable into", so therefore you can see that, given a sequence of trees T_i and the corresponding function f which maps trees to the corresponding ordinals, we have that f(T_0) > f(T_1) > f(T_2) > .... Now, it is about ordinals instead of trees, so if you've learned enough about ordinals you'd know that they are well ordered, so we can't have an infinite decreasing sequence of ordinals (this has the upshot of meaning that TREE(x) is finite, though you first have to prove that the trees do, in fact, correspond to ordinals under the relation). In addition, the ordinal structure which it does correspond to is known to be large, meaning that TREE(x) can get very large.

Then we have Rayo's number, which is explained in the video, but it's somewhat intuitive why it is so large: lots of numbers can be defined in Rayo's "microlanguage". It's actually super expressive, and some pretty large numbers have already been defined explicitly in it, while others are "almost definitely definable in it" because most of mathematics is built on abstractions of first order set theory, so there is a somewhat easy, yet very tedious, way to convert definitions of stuff like the busy beaver function into the language at a relatively low amount of symbols (maybe like fifty thousand or something).

Note that its impossible to compute busy beaver function for values bigger than (i think) 6. Well never know more than 6 values about our precious function
Correct!
I’m more interested in this random video than the entirety of my Math 3 class that I just had an EOC on and idk why 😭
Also if there was some kind of function to determine the digit count of any number (including decimal places), you could just take a repeating decimal like (1/3) and multiply it by itself when plugged into that function, and you now have an infinitely high value
Could you show big big SCG(100) is
Yup! I thought about putting that in this video but decided not to as it would make the video too long. I will put it in the next big number video 👍

TREE(this)
IIRC the game had rules where they couldn't just say "that plus one" or "TREE(that)", because otherwise it would go on forever.
I just have a question, and if it's stupid just tell me: what about rayos number + 1? wouldnt that be bigger?
that was a part of the contest that he didnt explaine, they could use a technique that was used before so just adding a one to rayos nummber would just be using rayos technique.
but yes adding a 1 to rayos nummber would make it bigger LOL
Not a stupid question, the video maker just didn't include the important rule of "doing something new" when presenting a bigger number. That's definitely a bigger number and you could make an even unfathomably bigger number like Rayo(Rayo(10^100)), but it just uses the same function as before and is not a new creation.
Must not have thought of Rayo's number + 1!!
rayo+1!2 < rayo^^^rayo
add one to that and i'm the winner now
TREE 3: "Hold my beer."
not even close 💀
You can define the TREE function using first order set theory in far fewer than a googol symbols. This means that Rayo's number must necessarily be more than TREE(TREE(TREE(TREE(TREE(...TREE(3)...)))))
I don't know exactly how far deep it could go but I know that I couldn't write it out. Even if I used every atom in the observable universe to denote another iteration of the TREE function.
I love how the box characters only have two emotions: happy, and pog
can you explain why double factorial is different than or the same as factorial of factorial?
It is different because you multiply every second number up to a given number rather than every number, thus making it much smaller. I was under the impression that in the actual Big Number Battle, they used double factorials, but it appears from further research that this was not so. They used single factorials.
Sooo... is Rayos number bigger than TREE(Rayors number)?
The most crazy part is the largest number that human can come up with right now or thousands years into the future is still closer to 0 than infinity.
So in order to win this competition why couldn't elga just repeat rayo's number but add one to it
The rules were that each player could not use naive extensions to create their next number. Adding one is considered a naive extension. Their methods of creating each new number had to be new and unique 👍 otherwise the battle would have gone on forever! 😁
it was actually adam elga who did the move of turning the ones into factorials
is TREE(TREE(3)) larger than rayo's?
No.
You can write TREE(TREE(3)... untill you die and you're still not close to Rayo's number.
@@XtreeM_FaiL so even like a million TREE(TREE( thingies its not close to rayo's?
I think he meant single factorials
how about limit of extending
What's that?

brilliant video! had me hooked not just because of the awesomeness of the content. well done. thank you
I'm glad you enjoyed it! 👍 😁
ok thats impressive but what about busy beaver(rayos number)
Unfortunately, that's not even close to Rayo's number. Busy Beaver is a fast growing function but not even close to the growth rate of the Rayo function.
@@jazlearn5147 The busy beaver that terminates with the most consecutive 1s with rayo's number cards is smaller than rayo's number? I highly doubt that, but just in case, rayo's number + 1

Rayo(10^100) = Rayo's Number is indeed large.
But how about Rayo(Rayo's number)?
What about Rayo’s function of Graham’s number?

Or Rayo(TREE(Graham))
@pyrotechnicsguy8346 That's even bigger!
ME: Let´s if your number is x, mine is x + 1.
That's called the successor function, and it's not necessarily a number. But I'll allow it 👍 😆
If your number is x, mine is x-2.

my first thought when reading the title is to just an another 0 .then after the opening clip, what if you just said factorial one more time lol.
5:23 tree function grows faster. Tree(1)=1, Tree(2)=3, Tree(3)=MORE THAN 10^100000000000!!!!!!!!!!!!!
Surely the Subcubic Graph function is faster growing than Busy Beaver
I believe it is 👍

Is infinity not allowed
Infinity is considered a concept as it is the idea that you can go on forever, thus making it not a number 👍
@@jazlearn5147 so technically it's considered cheating

I'm sorry, I'm dumb, why does this work?
So a factorial(!) usually means to multiply every number up to a given number. So 5! means 5 times 4 times 3 times 2 times 1. When we use double factorial, instead of multiplying each number up to the given number, we must multiply every second number, so 5!! is 5 times 3 times 1.
Does that make sense?
I was confused at first as well. You would think it would just be (5!)! but it isn't.
@@jazlearn5147 no, it was. he wrote more than 2 factorials. that means 11!n (n = how many 1s were after it)
he was using repeated factorial notation to make a very large number.
@kiwi-2 Thanks for the clarification! I must have missed that! 👍 Sorry about that!
Is this truly so? Which grows faster, BB or TREE? And do they ever intersect?
TREE(n) function goes 1, 3, and then huge. BB(n) remains small-ish up to 5, and then it becomes huge but probably wouldn't surpass TREE(n) until n equals 8 or 9. They do intersect, and BB grows faster overall.
Wow i love this video! Is it not possible to do BB(Rayo(10^100)) or am i just dumb.
Thank you!
If you do BB(rayos number), you are substituting into the slower growing function. Even though the busy beaver function is the fastest computable function, the rate of increase of the Rayo function far exceeds it, so it would be best to do Rayo(BB(10^100)).
It's hard to know if your number is bigger than Rayo's number due to the sheer size of these numbers, but Rayo(BB(10^100) is definitely is bigger! 👍
@@jazlearn5147 ok i understand thanks!
@@jazlearn5147 I would go with Rayo(BB(Rayo(BB((10^100!)+Rayo(BB(Rayo(q)^Rayo(q))))), where q is defined as BB(Rayo's number^Rayo's number)
Just wanna ask: How about TREE(10^Rayo's number)?
That is significantly smaller than Rayo's number. Rayo's number is incomprehensible in size. You could literally do TREE of TREE 10^Rayo's number times, and I believe that Rayo's number will be larger.
@@jazlearn5147 It's obvious that TREE(10^x) is bigger than x for any x

HOLD ON
Numberphile's version of the big number duel has elga making the factorials!
11!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Yeah this version is simplified a lot so that more people can understand it.
how is 11!! = 10395, when 11! is already over 39 million?
Rayo's number to the hexation of rayo's number😵
(Tree(Tree(that absurdly big number))) tho the hexation of (that absurdly big number)
but WHY does it grow so fast? is it because you can define the other numbers within rayos number and thus they are just subsets of it so no matter how many times you chain TREE(3) into itself TREE(3) times rayos number can just define that in a few more symbols and you cant out juice it?
Essentially, yes!
Pi with no decimals x googleplex + rayos number
cool! Does any one know how the size of those numbers compares to g63 and the TREE function?🤔
These numbers are A LOT bigger! Like a lot... 😆
Firstly, 11!!!!! does NOT equal ((11!!)!!)! and even if we consider doing that, why don't you just use factorial like this: ((((11!)!)!)!)! (That's so much larger)
You are very correct. It was initially a mistake I made, but I left it in there because who doesn't like to learn about double factorials! Lol
Legends know that the biggest number is FOREST(3)
I think you meant TREE(3)?, from what I've seen yes it's an unfathomably large number, magnitude bigger than a number like that of the Graham's Number, but still pales in comparison to Rayo's Number, by a huge margin.
@@Vxrtu No, the joke is that a forest is bigger than a tree, so FOREST(3) is even bigger than TREE(3), because a whole forest is much larger than just a tree.
Yes... Whatever the biggest number is that you can define or imagine, and then add 1.

Yes. Those are bigger 👍
Infinity isn't a number. It's a concept.
