   Thanks for your feedback.  Re:  10^-15 meter as the fineness   
   limit on the measure of the universe, it’s notable that, assuming   
   the universe volume is roughly (10^26 meters)^3, separating it   
   into identical volumes by dividing by (Ru / Rpl)^2, these tiny units   
   also have radii roughly equal to 10^-15 meter.  Ru is universe   
   radius and Rpl the Planck length.   
   Following Ng, each one can be seen as having one degree of   
   freedom.  Ie: About ten to the one hundred twenty-two degrees   
   of freedom, as the universe computes itself from time zero   
   onward.
