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.

  • $\begingroup$ You got your timing wrong, the migrated question was here first. It was migrated on 28$^{\text{th}}$ December and answered the following day. It was edited a couple of hours ago, however, and probably that brought it to attention. But that doesn't matter, which will be closed as a duplicate and whether they should be merged isn't determined by age. $\endgroup$ – Daniel Fischer Mar 12 '15 at 12:24
  • $\begingroup$ Apparently I didn't read the "migrated from" banner very carefully, or I would have the question migrated some time ago. My mistake. I noticed the question because it came up on the "top questions" list for activity, so I believe you are right about the edit. $\endgroup$ – David K Mar 12 '15 at 12:31

Neither option is correct.

You should flag either one of them using the free form flag, and ask for the questions to be merged.
