Yes, but it becomes very tricky to imagine something of zero size creating a finite length? And there I would say it won't matter how we refer to it, as being circles or straight lines? And in a 'bit universe' we do seem to expect a finite definition of a length (Plank scale), don't we?

I do like points, but dimension less points, of no scale, defining one?

How do they do it, if they do it?
