Let's take a given circles' circumference as a 1-dimesiaonal spaces where all natural numbers are found along it as a collection of points (0-dimensional spaces).
By using equal sizes of 1-dimesiaonal spaces between the points (where each point represents only once some natural number) we know that in terms of finite cardinality these clearly distinct points have opposite points (which are located at the half length of the circles' circumference) if the finite cardinality is even, or don't have opposite points (which are located at the half length of the circles' circumference) if the finite cardinality is odd.
Here is some example of odd or even cardinality (

Even cardinality is seen by the blue and purple cases.
Odd cardinality is seen by the red and green cases.
In case of infinite cardinality, we actually can't determine if there is or there is no opposite point (some distinct natural number) which is located at the half length of the circles' circumference.
Question: Why is that?
