Arthur A. Eddington, "The Mathematical Theory of Relativity" (2nd ed.),
Cambridge, 1924, sect. 47 p. 106:  (The success of thermodynamics) "...
suggests striving for an ideal -- to show, not that the laws of nature come
from a special construction of the ultimate basis of everything, but that
the same laws of nature would prevail for the widest possible variety of
structure of that basis."

Some of my research indicates that any model of reality built on a
Hausdorff space (i.e. you can always distinguish two non-identical
points) has laws similar to Einstein's theory of relativity.

"Information Mechanics" is indeed very interesting.  I chased down an axiom
that I couldn't swallow, but the fact that so much realistic stuff comes
out of that model, suggests that the flaw is repairable.
