I don't see why people would have a problem with the possible FTL nature of a 
correlation in the EPR experiment, or wave-function collapse, but have no
problem with the idea of the entire universe being causally split in the mere
seconds it takes for someone to make a measurement, each and *every* time a
measurement is made. Perhaps one of the Everettistas could explain this to me.
If the split starts at Alice and travels at c toward Bob, if Bob is space-like
separated it won't ever reach him.

If you imagine that the universe is a sheet of paper, it doesn't matter what
dimension you split it in, whether you simply rip it in half or peel it apart
along the plane, the split still has to travel at some finite speed. Or lets
say it's simply the information in the universe that is splitting like a file
being copied. The larger the file, the longer it will take to be copied, even
if you don't edit the file to make sure that one of the particles had its spin
reversed. Of course if MWI is *magical* or something, then I suppose the
splitting makes sense.
