When does a universe split? The relativity of simultaneity causes problems: one observer will have to interpret the universe as splitting in one way and then the other, while another will observe the opposite ordering. My personal favorite interpretation is the relational interpretation [1], where we just stop asking nonsensical questions about the universe. It does away with problematic notions that arise from our biases as human beings. [1] http://plato.stanford.edu/entries/qm-relational/ http://plato.stanford.edu/entries/qm-relational/
