I suppose there is some interference between
these worlds, (and between gts's too?). Also
according to D.D. there is some interference
(the shadow photons).

Btw, I'm trying to explain, by means of the MWI,
this very strange, and simple, and interesting
effect.

"There is no evidence that a single photon goes
through a single path (in the interferometer,
or beam splitter)"

So, let us have one 45° polarized photon P,
and a (very simple) beam splitter S, which allows
two different paths, path one for vertical polarized
photons and path two for horizontal polarized
photons, and also a 45° pola-filter F, and a
detector D.

Our 45° polarized photon P hits the beam
splitter S ......

             path one
             -------- |
P ------ S < |F ------- D
             -------- |
             path two

Now imagine that the 45° polarized photon P
goes through path one (vertical polarization)
and then through the 45° pola-filter F. The
probability of being detected at D is 0.5!

Imagine instead that our polarized photon P
goes through path two (horizontal polarization)
and then through the 45° pola-filter F. The
probability of being detected at D is, again,
0.5.

In any case the probability for our photon P
being detected at D is 0.5.

But the experiment shows that every each photon P
is detected by the detector D!

Thus we can not say that the photon P goes through
path one *or* through path two.

(It is also wrong to say that the photon splits
and goes through both paths, of course)
