Infinite Nothing
If you look at in in number terms, infinity is tecnically nothing as infinity is no defined, chosen number-it's simply stretching on for eternity.

Um no - read up on ordinal numbers young einstein. (and don't double post)

a circular path is infinite, yet you call it that it does not exist?
infinity does not have a beginning or an end like your puny line segments.

An infinite line doesn't have a beginning or an end. It only has a center. Zero. After that it either increments towards positive infinity, or negative infinity.

You could also have something diverge towards infinity, or converge infinitely towards zero.

Furthermore, a circular path is not infinite in all frames of reference. If I'm simply describing the path itself, it can be as finite as 2πr

Is that n supposed to be pi?

Anyway, infinity is just a fancy way of saying "unlimited." Like in a video game, when you unlock "unlimited lives," you can also say "infinite lives" and they both be equally correct. Therefore, infinity does have a value. The value is, well, infinity!

It's not an 'n'. It's a π symbol.

Stating that infinity has no value is very sloppy logic, IMO. Infinity can have varying effects on equations depending on its frame of reference, so in that sense it definitely has a value, even though that value is not an integer.

Whatever. You know what I mean. Is it pi?

I didn't state that it had no value. I stated that it's value was unlimited.

That's the symbol for pi. One of those Greek letter thingies.

I don't know if viewing infinity as a variable or a non-static integer is the correct way of looking at it. It's more like a modifier or an indicator, usually used to show the direction in which an equation proceeds (such as growing exponentially towards infinity, or decreasing fractionally towards zero). I can put infinity into a variable, but since I can't actually apply a number to infinity it can't really be considered like a number.
