I have said over and over that if Many Worlds is true then ANY change produces another world, a K40 atom in my bloodstream decaying is obviously a change, so obviously another world is produced. *> I think (and know from experiments) that the measurement in an > orthogonal basis is necessary to have an interference pattern appear.

If the which way information is encoded then obviously the worlds will be different, so obviously they will not merge, so obviously there will be no ambiguity about the photon's path, so obviously there is no interference. But in Deutsch's proposed exparament where is that which way information encoded?? And what exactly is your prediction anyway? There can be only 2 possibilities, at the end of the experiment when the photographic plate is developed will there be interference bands on it or will there not be? When Deutsch's experiment is actually performed, and someday it will be, I have already said I would give 2 to 1 odds that there WILL be interference bands on that all important photographic plate, so now it's your turn to put your money where your mouth is as I have done.
