Primes

Is infinity a prime number?

Ha ha ha, maybe you should end the thread yourself and save yourself some dignity.

Infinity is not a number, it is a free man

infinity is divisible by 0

No. And as a bonus, here is a proof which doesn't require an "infinity is not a number, etc, proof".

(1) By definition, a prime number is in the set of natural numbers.
(2) Assume infinity is a prime number.
(3) By definition of natural number, there exists a natural number X such that the successor of X is infinity. IOW, there exists some number that equals (infinity-1).
(4) Thus, infinity = S(S(S(S(...(1)...)))), where S is performed a finite number of times (by definition of natural number)
(5) Therefore, infinity is a finite number.
(6) Infinity is not a finite number, therefore we have a contradiction. Thus, infinity is not a prime number.

QED.

"INFINITY" is obviously finite

FAIL - you proved that infinity isn't a number, then used that to prove the original claim (it did require that "infinity is not a number", you just restricted it to naturals)

You're a gigantic idiot. You used the fact that infinity is not a number as your contradiction, yet you claim not to have needed that fact. Your proof didn't even have anything to do with primes.

∞ = ∏ n∈ℙ n

∞ is the most composite number of all.

Infinity is not a number so it is not an anything number.

Correct. Or, more correctly, infinity is not a real number, and thus is not prime.

I don't have the mathematic acuity displayed by some of posters here, but I thought I'd add my two cents anyway: A number is the concept of something finite(1 piece, 1 second, etc...), it has a beginning and an end(if you have 5 pieces of candy, you start with the first piece and end with the fifth). Infinity is the concept of something that has no end(the set of natural numbers) as well as something that has no beginning(the set of real numbers). To be a number is to have a specific beginning and a specific end. to have only one of those conditions is to be infinite.
A prime number is a number divisible only by 1 and itself.
The heart of this thread is this: Is the concept of infinity, when represented in the form and fashion of a number(the lemniscate or "lazy eight" symbol) divisible only by 1 and itself?
Because the concept of infinity is the concept of something without a definite number, it doesn't matter if you divide it up into one piece, 2 pieces, or 2 million pieces. Each piece is infinite. Therefore, because infinity can be divided by any number into equally infinite pieces, it is not a prime number.

>A number is the concept of something finite(1 piece, 1 second, etc...), it has a beginning and an end(if you have 5 pieces of candy, you start with the first piece and end with the fifth).
What the fuck? You have a painfully stupid way of looking at numbers.

By the way, your definition of prime number is incomplete. You need to exclude 1. You should say a prime number has exactly two natural divisors, or simply state that it has to be larger than 1.

I especially like how your definition of prime number starts with "A prime number is a number-" Guess what, INFINITY IS NOT A NUMBER, so it's not a prime number. End of story.

you FAIL infinity is not a number. It is a concept.End the thread now.This is now a sage.

>>14
You FAIL that was not a sage. Sage goes in email field. End this thread now. This is now a sage.

False. The purpose of the statement "infinity is not a finite number" was not to say "infinity is not a number." It was used to say "infinity is not finite."

Therefore your criticism failed.

My entire proof was dedicated to proving, based on the definition of "prime number" and "finite" vs. "infinite" that infinity is not a prime number. Nowhere in my proof did I use the fact that infinity is not a number!

>>1
yes

>>16
False. The purpose of the statement "infinity is not a finite number" was not to say "infinity is not a number." It was used to say "infinity is not finite."
ALL NUMBERS ARE FINITE. Saying it's not finite is equivalent to saying it's not a number, and none of that has ANYTHING to do with primes.

You're fucking stupid as shit. Get the fuck out of /sci/.

Infinity is a PRIME topic for fighting over if nothing else.

lol sage.

>>18
That was the point of my post, you fucking dumbass. The guy asks if infinity was a prime number, and I proved it to him without saying infinity is not a number. Basically, I did the same thing but by making it beyond "fucking obvious" by getting it hinge upon the fact that the fucking word "finite" in "finite number" makes it obvious.

Now excuse my while I go roll my Ph.D. in low-dimensional topology up tight and smoke it.

Basically, what I'm trying to say is NO U.

>>21
You have a Ph.D.? Wow, you MUST be right! Why didn't you say so earlier!?

You're pretty cool, Anonymous.

>>22
Damn straight I am. And boy that diplomablunt was tight.

This id thing is kind of killing the 'We are anonymous'
it's like forced tripcodes

>>24
CTRL+SHIFT+DELETE

Now that the original question has been settled by the diplomablunt smoking topologist (with a PhDizzle!) let's move on to more pressing questions:

where is time?
how fast do thoughts move?
how much does love weigh?
why is rosie o'donnal so fat?

Seriously no one can answer questions like this!  And the first three AREN'T EVEN QUESTIONS!!! Just cuz you can put fucking words together doesn't mean it corresponds to a meaningful statement or inquiry.

dumbass
