I don't know about the "concept of infinity is self-contradictory and thus has to be rejected"

Can infinite lines exist in the physical universe?

I said nothing about "lines", "infinite" or otherwise. All I said was

I don't know about the "concept of infinity is self-contradictory and thus has to be rejected" but it's certainly is "**here-be-dragons territory**".

I was meaning that the study of infinity is a deep one. Can one infinity be bigger than another?

There are

an infinite number of positive integers, say

*infinity*_{1}, and there are

an infinite number of real numbers lying between 0 and 1, say

*infinity*_{2}, hence there are

<< and

**here-be-dragons territory** >>

*infinity*_{1} times

*infinity*_{2} real numbers greater than zero, say

*infinity*_{3}.

So order the different "infinities",

*infinity*_{1},

*infinity*_{2} and

*infinity*_{3}.

I'm no mathematician, so by now I'm thoroughly confused. I'll stick to counting 0,1,2,3,4 . . . . . . .
