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.              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
