It's easier to imagine that (infinitely?) many pre-existing worlds just dived up 10:1 than that 10 new ones are differentiated. BrentIs this any different from Wei Dai's interpretation of quantum mechanics, described here: http://www.weidai.com/qm-interpretation.txt
Wei Dai's formulation says there is no temporal connection between psi(t,x) and psi(t',x'), but then he has to explain the appearance of temporal causality as just an accident whereby some psi functions are more common or have more weight. I don't see how that can work. It introduces the problem of everythingism, but quantum mechanics doesn't allow that *everything* happens.

How does Wiseman (appropriate name!) distinguish their theory from the MWI experimentally. (PS Apologies I don't have time to read the paper at the moment.)

No new universes are ever created. Instead many worlds have existed, side-by-side, since the beginning of time. “ Regarding the interference patterns detected by the single electron double slit experiment (first performed in 1974 at University of Bologna) According to Wiseman and his team this interaction between parallel worlds leads to just the type of interference patterns observed – implying electrons are not waves after all. They have supported their theory by running computer simulations of the two-slit experiment using up to 41 interacting worlds. “It certainly captured the essential features of peaks and troughs in the right places,” says Wiseman.
