In the same way that 'three' is a word.

Infinity is a concept, existing beyond the realms of human reckoning.

nothing can be infinite, and you cant even prove it exists

i'll try right here

1,2,3,4,5,6,7,8,9,10,11,12,13,14,.....

a trillion quintillion quintillion quintillion quintillion..........

see?

infinity has been used to describe things, so it isnt just a concept.

for instance, the mass of a black hole is called its singularity, and apparently, a singularity is an INFINITLY small point of INFINITE density. thats ridiculous!

if somthing has infinite density it would exert gravitational force over the entire universe that is so strong it would destroy everything! and somthing infinitly small would not occupy space and therfor couldnt exert gravitational force!

a singularity is not an INFINITLY small point of INFINITE density, it is a very very small point of a lot of density.

and the guy who discovered singularity was just to lazy to calculate HOW small or HOW dense the thing was!

The whole point of infinity is that it's a not a number, and you can't count to it. It is, perhaps, best described as eternity. Since 'eternity' is such an abstract concept in itself, infinity is a thing that only exists as the answer to an unanswerable question. Impossible to quantify, or imagine coherently, it is an awesome prospect.

But does it exist? Certainly.

I invite you to take out your common-o-garden pocket calculator, and tap in (any positive integer) divided by 0.

You can fit an infinite amount of nothings into a whole number - however many nothings you have, you will never fill a something. That's what infinity means.

Infinitely _small_ is an even more interesting concept.

Imagine (I know I'm going off track but I'm enjoying this):

3 = 0.3333' (the ' representing recurring).

3 x 0.333' = 0.9999' ?

Surely all those infinite threes going off into the distance can each be multiplied by 3 to get 9.

Why then does 1/3 x 3 = 1 if 1/3 = 0.333' ?

We must conclude that it doesn't - the difference between 0.9999' and 1 is an infinitely small value. The value, however, surely exists somewhere. This begs the question; if an infinitely small value can exist, surely you must be able to add up small values to make large ones. An infinite number of infinitely small values would be needed to make _any_ value.

Is all maths a bit shaky?

Probably not, but it's a thought.

I'll admit, more enthusiasm went into this post than genuine knowledge.

Actually infinity is not a number, it's an expression.

3 is a definate number. There is no "number" infinity. An object can never reach infinity, it can only approach infinity. With no definite value infinitiy is just a word not a number. Any more than A+B is a number.

As said, infinity can't be counted as a number; it is a word. Lets say, and don't take me as someone who is religious, God... God is infinite. He is, or alleged to be, ever-lasting, continous, etc.

It is not a number, but another word for something that is ever-lasting and continuous.

It is not expected for you or anyone to understand infinity itself because it is impossible to do so with our finite brain processes, but you can understand, or perceive the concept.

Time does not at all apply to infinity. It is free from all restriction, and is eternal, meaning it never ends. And nor does it begin. It just _is_. It is the source of all that is. Beyond that we cannot know, as finite humans in a finite ‘world’.

Infinity is a number as much as Felix the Cat is a cow. Its an idea.
