agree with (‘ra’) use of ‘density’ vs. ‘dimension’.
most of our math based on very arbitrary decisions in 1600s and early 1700s.
there is no such thing as one dimension or two. three dimensions could as well be measured in four directions as with points of tetrahedron. (for some uses this will come about anyway- another ‘cartesian’.) the ‘fourth dimension’ concept became popular with song out of late forties referring to einstein’s ‘fourth dimension’. those words had to come out of the song, as time goes by, for the movie as casablanca set just prior to operation torch, morocco, and prior to bombs. just google for original lyrics. adding ‘time’ to height, width and breadth is worse than three apples and an orange. it is three apples and an orange smoking a cigar and toting a machine gun.
i know what someone means when stating ‘other dimensions’ and do not feel at time that there was any better expression. i use ‘other realities’ and do not differentiate as to one being ‘higher’ or ‘lower’. ra for 'ra'.
