Can you please show me a spread sheet with the heights that the tree has had Not just exactly 1 year after you planted it and exactly 2 years after you planted it but also provide values between 0 years after you planted it and 1 year after you planted it and values between 1 year after you planted it and 2 years after you planted and all the way to now. Ps it should not be too hard to figure out the heights for whole numbers like 0,1,2,3,4... even if some of them you have to use a weird mathematical function to show the answer (Like even weirder than power towers.).

I thought of it like this. The tree function gives much larger values than the g function. So at the enormous scales that we're talking about, all that matters is what is inside the tree function. So tree(g64) is better than g(tree(64)) because you're giving a bigger number to tree. It doesn't even matter what g is doing at this point.

So sure, Tree(Graham’s Number) is big. But I have just been exploring the harmonic series (1 + 1/2 + 1/3 + 1/4 + 1/5 …). It is divergent. It takes around 10^43 terms just to get it to sum to a hundred, and it gets way way slower after that. So my number (‘Geoff’s Number’ if no one has claimed this before) is: “The number of terms required for the harmonic series to sum to Tree (Graham’s Number)”.

If you look at it through the levels of googology: level 0 is all the single digit and small numbers tending to zero; then level 1 goes from double-digits to a million; then level 2 goes beyond this all the way to a million digits (yes, googol and virtually every number we can practically deal with in our observable universe doesn't even get past level 2); level 3 starts entering the realms of tetration with googolplex and the likes; level 4 goes well beyond googolplexian and so on. You can see how going up just one level in the realms of googology gets to even greater magnitudes much further away than the levels before it. Well, G1 sits around level 6 or 7 and then G64 is much further at level 12, with fw(n) starting here or the level before it (11) let that sink in. So you can see that the difference between 12 levels is the difference between mere counting and shooting past G64 by iterating the number of arrows. Now you run through all the ordinals from omega through epsilon, zeta, eta until you reach the insane gamma-zero; the latter is all the way up to level 100 in the fast-growing hierarchy, meaning that counting to even G(G(...G(64))) [G64 iterations] would be much faster than using the G(n) function (or even f-epsilon0 for that matter) to reach the monsters produced by fgamma-zero(n). However, even then TREE(3) would laugh at this, as it's all the way up in level 120. That's right, an entire 20 levels ahead of fgamma-zero(n), which is insanely further apart than 0-1 and G64 which is merely 12 levels. This means even using fgamma-zero(n) to reach TREE(3) would be much slower (which is still an understatement) than merely counting to G64, even if you were to count in base 1/G64.

It's amazing that even without the ordinal Mathematics, we can still tell that TREE function grows (way) more quickly than Graham's function. TREE(n) literally goes from 1 to 3 to something that is way way way way way bigger than Graham's number, while G(n) needs 64 layers to go from 3^^^^3 to Graham's number. It's absolutely safe to say that at least the numbers G(1) to G(64) are all within the gap between 3 and TREE(3). The jumping between G(n) is essentially stationary compared to that between TREE(n).

All the ordinals that were mentioned in this video were still countable, i.e. they can be viewed as representing a (non-standard) ordering of the natural numbers. That is to say, the transfinite ordinals play the role of intrudcing jumps (in this case the jump is taking the diagonal in the constuction of f's). As such, the cardinalities of any of those ordinals is N, and thus all still smaller than that of the reals R.

Just wait, one day they'll finally explain the Busy Beaver function BB(n), which grows so fast there literally cannot exist a function that can compute any of its digits. It's insane just how fast it grows. I heard that even getting a lower bound on BB(20000) is impossible in ZFC. Of course, BB(n) is tiny compared to its relativized cousins. And we aren't even out of the lower attic yet. In the middle and upper attic, there are numbers so large that you need to add extra axioms to ZFC in order for them to exist.

It was quite intuitively obvious to me that Tree(n) was way bigger than g(n), the best way I can describe is that 3 is the first number in the Tree sequence to unlock it's full power, as you always have a first sacrificial colour, so you're kinda playing the game with n-1 colours. 0 colours for n=1 obviously stops, 1 colour for n=2 also has to fundamentally stop really quickly, but for n=3 you finally have 2 colours to play with. If 2 colours already gives the illusion that Tree(3) might be infinite at first glance, and remember this is the first "real" amount of colours to unlock the Tree game, then it only follows that this graph is exploding quicker with any more colours to play with from that point than anything you can make with normal iterations of mathematical functions, no matter how awesome a way you have to write them to become really big.

@@PC_Simo If you look at it through the levels of googology: level 0 is all the single digit and small numbers tending to zero; then level 1 goes from double-digits to a million; then level 2 goes beyond this all the way to a million digits (yes, googol and virtually every number we can practically deal with in our observable universe doesn't even get past level 2); level 3 starts entering the realms of tetration with googolplex and the likes; level 4 goes well beyond googolplexian and so on. You can see how going up just one level in the realms of googology gets to even greater magnitudes much further away than the levels before it. Well, G1 sits around level 6 or 7 and then G64 is much further at level 12, with fw(n) starting here or the level before it (11) let that sink in. So you can see that the difference between 12 levels is the difference between mere counting and shooting past G64 by iterating the number of arrows. Now you run through all the ordinals from omega through epsilon, zeta, eta until you reach the insane gamma-zero; the latter is all the way up to level 100 in the fast-growing hierarchy, meaning that counting to even G(G(...G(64))) [G64 iterations] would be much faster than using the G(n) function (or even f-epsilon0 for that matter) to reach the monsters produced by fgamma-zero(n). However, even then TREE(3) would laugh at this, as it's all the way up in level 120. That's right, an entire 20 levels ahead of fgamma-zero(n), which is insanely further apart than 0-1 and G64 which is merely 12 levels. This means even using fgamma-zero(n) to reach TREE(3) would be much slower (which is still an understatement) than merely counting to G64, even if you were to count in base 1/G64.

I read a cool description of Graham's number somewhere, in terms of trying to picture it in universal physical terms. If my memory serves me, it went like this: It said that even the integer describing the number of digits in Grahams number could not be represented if you made every particle in the universe a digit, and the same would be true for the number of digits in THAT number, and even if you went down that "number-of-digits-in-the-previous number" scale, with each level down being represented by a single particle in the universe, you still would not able able to fit it into the known universe. I wish I could find that again.

One interesting thing is that not one could describe the *difference* between those kind of monster numbers without using substraction. I mean, we can construct numbers likeTREE(g(64)) and g(TREE(64)), just with addition, multiplication, exponentiation, and so forth, but no one can ever describe a procedure that could compute or even approximate their difference *d* = g=TREE(g(64)-g(TREE(64)) in finite time without using the substraction operation. I claim that this number, *d* simply does not exist. I claim that, against all appearances, the set of integer numbers is essentially full of void and maybe even it could be that card(N) is finite.
