I think one problem here which is being brought up by many, and a problem that plagues many interesting ideas: what’s the physical mechanism?
More important is the issue of just what the multiverse theory exists to accommodate. Timeline splitting would be the result of nature not actually “choosing” one part of a superposition of probabilities over another; they both exist in probability space or something like that. Human events like choices are incredibly macroscopic compared to the events leading to a multiverse. Ten years of activity should, in theory, lead to uncountable branches.
Other than the laws of physics remaining constant, nothing else does in theory, and so were talking about massive and continuous divergence, and convergence. You’d have infinite universes, some existing along similar lines, others radically different, but there would be no one tendency to converge or diverge; it would be chaos, expressed physically.
