An infinite series cannot be terminated. Of course an infinite number can terminate with a different digit. And clearly you didn't watch the video. For example, I showed .444... multiplied by 9. The result is .444...46. I have "read up on infinity", and infinity as we know it isn't how it works in algebra, no matter how much you want it to. My girlfriend is mad at me. Perhaps I shouldn't have tried cooking a stick in her nonstick pan.

(Same all the way down through 8/9) I did the math, and you didn't pay attention. 9/9 certainly is 1, but that's because you've magically hit the point where the remainder becomes divisible and can be added in, so it no longer remains invisible. Algebra doesn't work the way you think it does. Try again. Of course there's a remainder. Do you guys comment on videos that you don't bother to watch? If you multiply .111... by 9, it gives you .999..., not 1. That's how we check our work  if X/Y = Z, then Z(Y) = X. If it doesn't, then we did the math wrong. That's exactly what I'm saying... you did the math wrong. Stop doing it on a calculator... the calculator rounds off. Let me give you further math proofs. If .999... = 1 and X squared = X squared, then .999 squared should = 1 squared. It doesn't. 1 squared is 1, and .999 squared is .999...980...001. Even if you don't understand the math there, I'm sure you realize that two numbers ending in 9 multiplied give you a "1" on the end, not a zero (as in 1.0000....). 2X = 2X. But 2(.999...) = 1.99...98, while 2(1) = 2. X  X = 0, but 1  .999 = .00...01 (or negative .00...01 subtracted the other way). The math doesn't work. No matter what you do to both sides, it will never come out equal. My girlfriend is mad at me. Perhaps I shouldn't have tried cooking a stick in her nonstick pan.

Stick to the arguments at hand. Do you really want to keep getting told "you don't get what I'm saying"? We keep talking past each other  you insist on the argument being "reductio ad absurdum", as if that means that it can break the laws of math and/or logic. It doesn't. Let me put this in a logical proof. Please, point out where it is invalid or unsound. Premise 1: Cantor's diagonal argument creates a number, N. Premise 2: If a number is not found in the set of all real numbers, then it is not a real number. Premise 3: N is not found in the set of all real numbers. Conclusion: Therefore, N is not a real number. Good luck with that. My girlfriend is mad at me. Perhaps I shouldn't have tried cooking a stick in her nonstick pan.

Thing is, I got no bones with Supernova's passion, here. I'm thinking there's something wrong with transcendental infinity myself, only I'm too stupid to figure it out.

Hypothesis: The cardinality of the set of natural numbers is the same as the cardinality of the set of real numbers between 0 and 1. Argument: What the fuck? Here's a shitload of counterexamples that refute that hypothesis. Conclusion: The cardinality of the set of natural numbers is strictly smaller than the cardinality of real numbers between 0 and 1. ... That is all. QED. This is not my signature.
