Interference in the Multiverses

In order to explain why that one photon always ends up at detector two, we have to invoke the existence of a second p ton travelling up to mirror one. The refraction through the glass has the overal effect of causing constructive interference to detecto one and constructive interference to detector two. And so we end up with all of the photons going to detectorTwo. What on earth has got to do with the multifus? Remember we only fired one photon here. It's more profound than that. The one photon splits the universe into two and then recombines the universes into one. That's what interference is. Now, if you're not convinced by that, don't worry. We've
