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. - - - - - - - Jacques Mallah ([EMAIL PROTECTED]) Graduate Student / Many Worlder / Devil's Advocate "I know what no one else knows" - 'Runaway Train', Soul Asylum My URL: http://pages.nyu.edu/~jqm1584/
