I seem to recall that Tipler discusses something similar in PoI when
dealing with the universal wave function - logically consistent
worlds correspond to phase paths, while the inconsistent and weird
worlds are out of phase and hence have low probability of being
observed. Or something like that.

I haven't read Babour yet, but his theory seems to be very similar.
What I don't get is how he explains the emergence of causal-like

I have spent this weekend attempting to evolve causality in a
cellular automaton (I wanted to find a 2D automaton rule that
generated patterns corresponding to the space-time diagrams of a 1D
automaton), and it was definitely tricky.
