Several quick notes:
Yes, I am aware of SSCG(3) and Rayo's number but I thought that the video would drag on a little.
There are several minor errors with the visuals. Specifically at 3:19 where it says that 65536 is 2 tetrated to 5 rather than 2 tetrated to 4 and at 6:31 where it shows TREE(10^10) when I say "TREE(googol)" when it should show TREE(10^100)
When talking about graham's number, I said that g0 was 3 hexated to 3 but actually that's g1 and g0 isn't really a thing.
I excluded infinity because I intend to make another video covering exclusively infinities.
At 4:56 I display G↑ᴳ but, in actuality, this is an incomplete equation because you need another number on the other side of the equation. I basically just wrote the equivalent of "5 +" without a second number.
Sorry about the music being a little too loud.

Edit: Yes, everyone. I am writing a script for a sequel. You can stop mentioning SSCG(3), Rayo's number, BIG FOOT, the fast-growing hierarchy, etc...

7 is pretty big

"hey you want TREE(3) chips"
"what"
and then they were crushed under the unfathomable mass of an impossible number of chips

"hey,what's your favorite number?"

"🌲"

Remember, every giant number in this video is closer to 0 than it is closer to infinity

Fun fact: TREE(3) is so big that if you tried to count to it on your fingers, you'd need at least one more hand.

The number youll get when you spam the buttons on a calculator as a child:

"we cannot meet giants, but we may glimpse them on the horizon, and bask in their radiance" is such a fire line

the hospital's bill after they told me to drink more water:

We can never forget the original definition of a googolplex. "a one followed by as many zeros as you can write until you get tired"

The funniest part about TREE(3) is that the first color is “burnt” after the first tree and you build the entire rest with two colors only.

-Hello! Can I have f_10(10(↑10)10) Bottles of water, please.

-Man, what are you talking about...

The music put me in such a mood that I thought I was going to war.

You may have science on your side, but you'll never beat that one kid at the playground.

Could I have TREE(3) croissants, please? Keep the change

"Hey you want SSCG(SSCG(3)) chips?" "Yeah sure" (the multiverse gets crushed)

The mathematicians version of "whatever you said times 1 billion"

Edit: to be fair, the name of this video was "The Biggest Number" or something like that when I made this comment.

The fact that there are more possible chess combinations than atoms in the universe just blows my mind.

YES
the music is so good
4:30
it truly shows how excited some people get when it comes to math
thank you

5:04 when i heard lets draw some trees i knew it was over
