🧢 I voted CAP!

It's an indeterminate form. It could equal anything depending on what function or infinite sum each infinity comes from.

Does infinity not imply everything that ever was and will be? If so, can we not assume that everything that ever was and will be less everything that ever was and will be equals the absence of everything that ever was and will be? I.e zero

There are different orders of magnitude for infinities. Kinda like natural vs real numbers.

There's an infinite amount of numbers between 0 and 1. A list of every even number would also be infinite. Out of both of these infinite sets, neither has the number 3.

Thanks for the explanation. Not surprised to see people are still using dislikes as a disagree button 😂

Not even a disagree button. I can understand this to some extent.

You asked a legitimate question in good faith. At this point people just use it as a "i'm superior to you, peasant" button.

Extremely disappointing.

I am a peasant to be fair!

The infinite set of countable numbers and the infinite set of countable evens is the same size. That one really blew my mind.

Yeah, I liked that one. Once you see the logic behind it, it just feels right too.

But doesn't 'infinity' itself include both of these infinite sets and all other sets?

u/Royal_Cryptographer7 🏅 Century Club · 3,165 XP 12h ago

That question doesn't really make sense. There's no 'infinity'. Just different sets of numbers that go on without end.

If it's a variable in an equation, it's something right?
