Do you get the same result if you only send one photon through one slot? Or
do you have to send two photons through both the slots at different times?
Also, surely there are more than two probabilities (the two slots) there are
near-infinite probabilities (going through the slot at different angles,
hitting the thing with the slots in, going in the opposite direction...).
All of these seem just as likely as the photon going through one slot or the
other. So then, we only get new worlds from possibilities we measure. But
to measure our photon in this world surely the photon must be in this world
(or can photons and electrons pass between worlds?). If I happen to move a
piece of film in the way of one of the many (possibly infinite) paths of the
photon I'll measure it and therefore create a new universe. Now with all
these phantom photons floating about, sooner or later a large majority of
them are going to get measured in some way (Which could lead you to the
conclusion that a single photon radiates in a sphere but is only detectable
by measurement). We whould be getting a rate of millions of worlds per
photon (anyone want to estimate the amount of photons, the amount of
directions each could move in and how likely they are to be measured given
the size of space and the number of possible measuring devices within it?).
