This is a marathon of thought! :-)

This maybe relates to the Bremermann's Limit:
http://www.bestweb.net/~ca314159/BREMMANN.HTM You really need to read
Kosko's Information wave mechanics! I'll include it in the package...

YES! :-) The "distance" that is "crossed" in the quantum jump is
relatively null for the observer involved. Umm, the experiments being
down with quantum tunneling may give us falsifiability on this! It is
this notion that explains my initial discomfort with your wormholes
"First, we have discovered that photons which tunnel through a quantum
barrier can apparently travel faster than light (see "Measurement of the
Single-Photon Tunneling Time" by A. M. Steinberg, P. G. Kwiat, and R. Y.
Chiao, Physical Review Letters, Vol. 71, page 708; 1993). Because of the
uncertainty principle, the photon has a small but very real chance of
appearing suddenly on the far side of the barrier, through a quantum
effect (the 'tunnel effect') which would seem impossible according to
classical physics. The tunnel effect is so fast that it seems to occur
faster than light."

Yes! WE need to look at this very carefully! I say that the forward
jumps ... -->x1 --> x2--> ...
are dual to "backward jumps" ... i2 <-- i1 <-- ... of logical
implication (following Pratt). It looks like this:
... -->x1 --> x2--> ... Time
... |g |h ...
... <--i2 <-- i1<-- ... Logic
were g and h are infomorphic bisimulations...

Exactly! :-) I have used the word "mapping" because I did not know of a
better one. It is bisimulation!

Yes, this is why I advocate the use of fuzzy logic. Probabilistic logic
works too, but it is not intuitive to me. :-(

Yes! :-) I just try to think about how each observation involves its
own lightcone of causality...

YES! Existence is static, tenseless. Local actuality is a
bi-simulation... I perceive you by predicting your behavior in order to
act accordingly and you do the same back. Now, think of many observers

You are correct, my use of the idea of a mapping is a crutch. I am
learning how to communicate my mental pictures as I interact with you.
:-) It is the way that bisimulation works that lead me to use the notion
of mapping. Like Edelman's "re-entrant maps"
