If I would imagine a point then I make it as it has a dimension, so how actually I imagine it? for instance lets take I have distance like this:
1------------------------------20 , and I want to divide it by half , in other words I will put a "point" on the half of that distance in other words 1--------------------*---------------------20 , so I imagine that point which divide the distance by half like this .. but if so then the point "*" has a dimension because as you see in the graph it has dimension ..so how can I imagine it?
If you divided the line into 2 segments 10 each, how long is the "point"? 20 - 10 - 10 = 0.
You can draw the point however you like, it's still 0 size.

The * is not the actual point; it is only your representation of it. (Nobody can draw an actual mathematical point because it's not a real object.)

You never replied to my question, from about two months ago: What is the smallest positive Real number?
