Such is not available to all newsreaders. And should Google pass
someday, reconnecting the threads will be somewhat easier.

"My" theory? I simply insist that what can be measured is
"reality".

A theory starts with "assumptions", called postulates. Then some
model is constructed upon these "assumptions", usually involving
mathematics (quantification). The model then provides a
quantitative prediction. Such quantity can then be verified by
experiment.

You wish to make (IMO unwarranted) assumptions about an
underlying reality. Are you prepared for the fact that Reality
equally well supports different assumptions?

Quantum phenomenon underly all of this Universe that our "common
sense" is based upon. Quantum phenomenon are different if
witnessed/observed differently. Reality is trying to be like the
cover of the Hitchiker's Guide to the Universe... saying "Don't
Panic". The road really does rise to meet your feet.

You've not been at my house. If you have doubts about the
presence of food, you have every right to have those doubts. ;>)

Its OK. Nature will tolerate your silliness just so far.
Hopefully you will not seek employment in a Science field. I'd
hate to see another person going hungry. She has Her own rules,
and probably simple ones, but we cannot guess them... only how
they appear to be *today*.
