Think I had it in for the Multiverse concept at some stage; obvious change of mind now. Multiverse is the concept that instead of quantum waves collapsing into discrete recordable events, instead they create new universes, one for each event. David Deutsch champions this idea in connection with quantum computing where the possibilities in many universes can be utilised to compute results in this universe.
My problem with this is—after recent developments in the SRH—just linguistic. A universe suggests already that there is nothing outside it. To coin the term “multiverse” is completely oxymoronic and contradicts the meaning of universe. What quantum theory has opened is the realisation that what we thought was the limit of the universe is really just the limit of one bubble of space-time and other bubbles might exist. The “multiverse” is just a name for our better understood universe. For analogy how absurd to call the other planets multiverses in the days when the universe extended to just this planet and its atmosphere.
It might seem trivial but this lies at the heart of the SRH conception. A SRH Universe is unlimited just as Cantor showed that the sets of numbers are unlimited—that is not just that the numbers in each set is unlimited by the sets of infinities is unlimited in a way that can’t be grasped by any set! A fractal that extends in both directions with an infinite hierarchy of scale going upwards and downwards—the proper conception of Universe is something that in its very nature is ungraspable. The SRH says why very simply—if a body of understanding ever did try to grasp the scale of the Universe it would always need something outside itself in order to say something meaningful about itself. It cannot by the SRH ever say anything meaningful about its own existence, because that is a given from which the theory necessarily already depends rather than explains.
