a 100% chance its brother distant photon will make it through its filter
set at 78 degrees and for any photon that is stopped my my filter there is
a 100% chance its brother photon will get through a filter set at 168 (78
+90) degrees. The weird thing is that there is nothing special about 78 I
just picked it at random, common sense would say that
my
random choose made a billion years after both photons were created couldn't
have any effect on that other photon a billion years later and 3 billion
light years away

but common sense is dead wrong.

I don't know what you mean by "does not map", all I know it that the 2
boxes I described (and who Bell first described in 1964) COULD be built and
hidden lookup tables, even lookup tables written by God, can not duplicate
the way those boxes behave. Bell proved with just logic and high school
algebra that if photons behave by hidden variables the correlation between
adjacent settings on the boxes MUST be 2/3 or less, and yet my boxes have a
3/4 correlation. To prove that Bell and I are wrong and my boxes "do not
map" all you have to do is prove that 2/3 is greater than 3/4. How hard can
that be?

Every particle has a Schrodinger Wave associated with it and that wave is
analog continuous and deterministic, but that fact is not as important as
it seems at first because the Schrodinger Wave is not measurable, it is a
sort of mathematical fiction like lines of latitude and longitude; to get
something measurable you've got to take the square of the absolute value of
the Schrodinger Wave at a point and even then it will only produce the
probability the particle will be at that point.

Well... sort of. In the 2 slit experiment the photon acts analog when it
goes past the slits but after that when it hits the photographic plate it
acts digitally, it doesn't make a grey smudge on the film it makes a jet
black discrete spot, it's only when you send lots of photons through the
slots do those spots start to form the interference bands that you see in
textbooks because Schrodinger says some part of the film are more likely to
be hit by photons than others.

That is irrelevant, the important point is that the boxes could be built
and local hidden variables can never duplicate the way they operate.
