If point is zero-dimensional, how can it form a finite one dimensional line? (originally posted Dec. 27, 2014) was recently migrated here from physics.SE, although it already had answers. But on March 3, 2015, If point is nothing how come line which made up of set of points has length had already been asked and answered here.
As far as I can see these are the same question with the same possible answers. Does it make sense to close one as a duplicate of the other? If so, is the duplicate the question that appeared on this site later (via migration), or the one that was asked on a later date?
The migrated question already has about two screenfuls of comments from its time on physics.SE, so merely putting a link to the other question in a comment isn't going to be very visible.
