I'm not sure. Maybe when I've completely nutted out Brent's answer below it'll make sense, but it seems to me that a universe in thermodynamic equilibrium will still continue to diverge more than it merges, it's just that the different configurations of matter/energy will look much alike. In fact the number of possible equilibrium states is immense compared to the ordered states (hence the arrow at all), so why shouldn't the multiverse continue to branch out into more and more non-identical but similar-looking states?
I can't see why it would when there are no more microstates available in one time direction than the other. Assuming time symmetry of the underlying physics, a universe at thermodynamic equilibrium could play out with equal probability forwards or backwards, which would surely include MWI splitting/merging? -- You received this message because you are subscribed to the Google Groups "Everything List" group.
