<br>I haven't read Robin's paper on multiverse pruning, but one has to wonder (wild ass speculation mode on) whether retrocausation could be how the universes that don't work out jiggle the probabilities in the ones which are more interesting (I mean if you are going to reach across time, why not reach across both trans-space and time?).
