-Infinity doesn't exist.

1.There can be no number larger than infinity.
2.The sum of all numbers from -inf to inf is larger than infinity.
OR
2.The sum of all number from -inf to inf is infinity.
3.There cannot exist a -inf. It is inherent in saying "infinity"

I'd call you a retard, but then someone would post that new "I am not an retard" meme.

I'll do it then.

You fucking retard.

Let's start the "infinity is not a number" meme

Infinity is not a number. And infinity in terms of physical space does exist. If it has a finite limit, why does it end there and what is beyond it? Why couldn't it go just one further?

>>6
Space doesn't have to "end" to be finite. You can walk around and around and around the Earth for as long as you want, but that does not mean the Earth has infinite surface area.

OP's first mistake is assuming infinity is a real number that behaves just like all the other numbers he learned about in 1st grade when it most certainly is not.

Is it imaginary?

>>9
yes.  it hides beneath the complex plane.

>>7
That's a good example.

The lemniscate (∞) is often used as the symbol for infinity. (Where as a sphere, circle, or torus would work just as well), you can get understand the concept for infinity while tracing your finger around the edges of these shapes.

Imagine a small planet where it has this weird rule :
Your size depends on how close you are to the core of the planet
Now, the inhabitants build up a rocket to explore the universe and find the end of it.
The rocket flies, but while it goes away from the planet it shrinks, with result the invabitants never actually leave, it appears infinite to them but to us it's not.
This is funny, it has been proved wrong but in the same time they use it as a rule at maths.

>>12
Let's try to find a possible metric for this.

ds^2 = -dt^2 + cos(pi*r/2)[dr^2 + r^2 domega^2]
0<= r <= 1

Does this work?  Can light get to the edge?

Review "BEST IN MATHZ" thread. Someone with a math pedigree more prestigious than yours declared infinity a number while we weren't looking. He also declared null set to be a number too. Who wants to go shoot that guy?

>>14
"Nullity" didn't do anything that hasn't been done for a long time already. He gave "undefined" a new name and a symbol. The properties are all exactly the same, and it clarifies nothing in mathematics or in his own field. The resulting set (R union {nullity}) is not a field, much like in every other similar theory. Until he actually provides some example of when this notation is useful (the examples given in his own field, Computer Science, have all been adequately and simply handled with exceptions for years), it's no different than me saying "let's call 1/0 'fuckyeah', then you can divide by 0! (in R union {fuckyeah})."

I don't know if this guy is a crank who somehow obtained a doctorate (it does happen - there was an asian "mathematician" who had a phd from a decent american university that claimed to have a counterexample to Fermat's Last Theorem after Wiles proved it, using some non-standard model of the natural numbers that no one else in the world uses), or if he gave a realistic explanation and the BBC took it radically out of context to make a more interesting article. In either case it is not a "discovery" as the article claims - the only original part of his work is the name and symbol.

wait, how can anything be bigger than infinite? You couldn't add all the numbers between -inf and inf because there is inf numbers between -inf and inf

>>16
there aren't any number between inf and -inf because infinity is not a fucking number

You do not set things to infinity, nor do you compare numbers with it, add, substract, multiply or in any way touch it. Do not taunt infinity. Infinity comes with a lifelong guarantee.

In calculus, infinity is for approaching. Any notation that implies otherwise is just convenience.  Infinity, as noted above, is not a fucking number.

You'll need posters and ASCII art. Educate.

this thread, is so fucking retarded :/ it makes me sad in my pants.

-inf+inf=0 fags
