        Everett's view, and the view of all MWIers I know, is that nothing
really splits.  There exists the wavefunction, which obeys Shrodinger's
equation.  That's it.  Qualitatively, the behavior of the solution to that
equation can be described as 'a tree of branches or worlds', regions of
large measure tending to form such shapes in configuration space.  The
effective probabilities are due to the fact that consciousness has greater
measure in regions of large |psi|.  See my home page for a computationalist 
interpretation of that.
