Nope, you fell for the classic sibling blunder:

What about INFINITY PLUS ONE!?

[–] CarbonIceDragon@pawb.social 47 points 1 year ago (3 children)

Last time I saw this kind of challenge it was on reddit and I just replied with ℝ, but people brought up that this leaves out complex numbers. I'll now contend, however, that any number not included in that isn't real.

What about quaternions and octonions and ...

Aren't there numbers past (plus/minus) infinity? Last I hear there's some omega stuff (for denoting numbers "past infinity") and it's not even the usual alpha-beta-omega flavour.

Come to think of it, is there even a notation for "the last possible number" in math? aka something that you just can't tack "+1" at the end of to make a new number?

[–] drbluefall@toast.ooo 20 points 1 year ago (1 children)

What you're probably thinking of is Ordinal numbers.

As for your second question, I don't think any "last number" could exist unless we explicitly declared one. And even then... I'm not sure what utility there would be in declaring a "last number".

[–] veniasilente@lemm.ee 1 points 1 year ago

I mean, whoever gets to declare a "last number" that works certainly will get some bragging rights. After all, you can only ever declare one.

...Right?

(I know math is very weird)

Which of the infinities? There are many, many :D

The smallest infinity is the size of the natural numbers. That infinty, Aleph zero, is smaller than the infinity of the real numbers, Aleph one. "etc."

See https://en.m.wikipedia.org/wiki/Cardinal_number

Oh no! Please don't tell me there are infinity infinities!

[–] weker01@feddit.de 4 points 1 year ago (1 children)

Unfortunately yes there are and it's a very big infinity of infinties....

[–] veniasilente@lemm.ee 1 points 1 year ago

Oh wow and here I was hoping...

...actually, I don't know what, but I was hoping.

Hi! I'm a mathematician, and if you want to know more about infinity, I recommend this video: https://youtu.be/23I5GS4JiDg

After reading how this thread is going I'm half expecting this to be a Kurzgesagt video or something equally "cutesy existential dread" inducing lol. Let's see what do I find!

i isn't a real number, you imagined it

[–] BolexForSoup@kbin.social 20 points 1 year ago (1 children)

From gatekeeping to gaslighting in 2 comments. Not bad!

What a girlboss

[–] callyral@pawb.social 4 points 1 year ago

not a real number

[–] Bizarroland@kbin.social 9 points 1 year ago

You also have to remember to put the +C at the end

Fred.

(∀x:Number(x)=T)(Name(x)="Fred")

I name every number Fred.

[–] ColdWater@lemmy.ca 2 points 1 year ago (1 children)

Didn't it 0,1,2,3,4,5,6,7,8,9?

[–] ILikeBoobies@lemmy.ca 1 points 1 year ago

Depends on the bit limit
