Since this effort is not instantaneous, transmission must exhibit a finite ratio of temporal extension to spatial size, such as that exhibited by the perspectival spatial shortening and temporal slowing in special relativity, with the smallest quantum «volume» in our epoch being expressed by, h, the famous Planck Constant.20 For any moment, a perspective that prehends something with
less spatiality than another, must prehend it «with more temporal duration.
