preprint description
EPR-like phenomena are (presumably) indeterministic, but they furthermore suggest that our world involves seeming-strange ``funny business.'' Without invoking any heavy mathematics, the theory of branching space-times offers two apparently quite different ways in which EPR-like funny business goes beyond simple indeterminism. (1) The first is a modal version of a Bell-like correlation: There exist two space-like separated indeterministic initial events whose families of outcomes are nevertheless modally correlated. That is, although the occurrence of each outcome of each of the two space-like separated initial events is separately possible, some joint occurrence of their outcomes (one from each) is impossible. (2) The second sounds like superluminal causation: A certain initial event can bear a cause-like relation to a certain without being in the causal past of that outcome. The two accounts of EPR-like funny business are proved equivalent, a result that supports the claim of each as useful to mark the line between mere indeterminism and EPR-like funny business. This is a ``postprint'' based on the version published in Non-locality and modality, T. Placek and J. Butterfield eds., Kluwer Academic Publishers, Dordrecht, 2002, pp. 293--315. The archive at contains two recent related articles by the author, ``No-common-cause EPR-like funny business in branching space-times'' (2002) and ``A theory of causation: causae causantes (originating causes) as inus conditions in branching space-times'' (2002).
