Serf's opinion follows: If we go by Everett-Wheeler+DeWitt, they were (correct if this is wrong please) non-specific on what caused the splitting, or uncovering the differences in parallel universe. My own emotional fav is that humans were 'evolved' to accelerate the sensing (making choices) upon what we sense, thus, causing more splits, or making choices that uncovered splits (your own choice of explanations is welcome). So, our species evolved to make machinery that travels outwards to also cause more split-ends. Any sufficiently advanced AI should do? To my way of thinking, Schrödinger's cat sits not in a box but astride Wigner's Friend head, ever-watching. The physics is kind of like medieval writers asking how many angels can dance on the head of a pin? Unless, some friendly, Neanderthal, trades-people Voob-In wanting to trade our sweet potatoes, for their ample supply of helium-3, it's rather pedantic to this peasant. It is excellent, however for scifi/alternate worlds fantasies. You could re-write every factual history say, of the middle ages to include south Africans or Chinese, in Europe, because, hey, it's another world and another world-line, etc. Superman's shows could be all-Black, because why not? It'd be their own universe(s) where the cause and effect of things simply rolled that way. Roll the dice and see what happens next? Comics writers have already done this. Whether these publications have been as successful as the old school ones, is something I have no idea of? Yeah, Deutsch's quantum computing might be occurring in other realities to account for the behavior? Or, there assuredly is simpler explanations done by other physicists, to be sure. So, I say that 3,238 angels can dance on the head of a pin. Now, the next question is what dances? Minuets or Electric Slide Boogie?

In 1905 Einstein discovered Special Relativity and said nothing whatsoever could move faster than light, but by 1915 he had found General Relativity and had to amend that to some extent, he still insisted that matter or energy or information cannot move through space faster than light, but he placed no speed limit on how fast space itself can expand. > In the MWI, worlds come into existence fully formed as it were, that is, >replete with copies of observers.

AG MWI doesn't say if a new universe is created instantaneously or if the new creation only comes into existence at the speed of light; it doesn't say because it does it need to, it works fine either way. MWI Is agnostic about that. > If your claim that the net energy of the universe is zero is associated with > the universe as a whole, not for some part of it, then it must be > speculative. No calculation can be done to establish it. Correct? Correct, that can only be established through observation and experimentation. However if General Relativity is correct and if empty space does contain residual vacuum energy (both those things can only be determined through observation and experimentation but the evidence is piling up that both are correct) then the net amount of energy in the universe is indeed zero.
