Cool.

How about if I gave you an object with one edge and one side, could you work out how long that is?????

the object is real and when I gave it to my daughter she thought it was cool

The way i see it and this may be completely wrong that everything that could possibly happen an infinite amount of combinations. This all happens within no time and at all times. So the universe time wise does not exist and lasts forever all at once. I am sure this will be explained when our grasp of temporal physics comes out of it's infancy. I think writer of Doctor Who, Stephen Moffat said it best to explain time. It went something like "Time is like a big ball of wibbly wobbly, timey wimey." .

No such thing as infinity.Everything that exists is finite, including a piece of string.

Shocking, who told you that? the centre of a black hole is infinitely small and infinitely dense. Mathmatical formulae can go on infinitely for example the nth term, space is reputed to be infinite. Just cos Einstein didn't like infinity due to him not being able to quantify it doesn't mean it doesn't exist.

I think the thread on mandatory kit proves the concept of infinity.

(Arrrgh, I mentioned it, but only once and think i got away with it!).

In theory (the bit about black holes I mean). there are lots of things that exist in theory only, so really they don't exist.

I thought it just tends to infinity. Infinitely small would be zero.

CL, infinity is not something that has to exist. It is a concept just as nothing is.

The idea of Fractals means the edge you are measuring could be microscopically rough, therefore not flat, and continue to be so the closer you look therefore infinite.

Does this forum really exist?

It lives in the virtual world of cyber space.
