The Multi Versus Is Refuted

If experiment works as predicted, there is no way of explaining any of it by recourse to a collapse model where all the universes but one cease to exist. So that's that. Whatever the case, the multi verse is eminently test e by this technique, and, in principle, falsifiable. If indeed the interference fails to happen as predicted, then parlox, david duch's experiment has roundly refuted,. the multiverse quantum theory would then have our hugely open problem about how observation works  and why it is so fundamental to the nature of the universe. We would need to develop a new physics of observation and measurement. And physics would become, in part, fundamental.
