Backward causation in reverse time must be dynamic, i.e., accommodate a variable past. There are various ways in which dynamic backward causation (DBC) in forward time could operate. If DBC operates in Einstein–Podolsky–Rosen (EPR) experiments according to a particular account called observer-world brancher theory, then DBC can be mediated by fast tachyons. In a laboratory reference frame, for arbitrary geometry, at least one EPR tachyon per run collides with an EPR bradyon (or its associated tachyon) prior to that bradyon’s detection. EPR tachyons, mediating DBC in accordance with an appropriate attribute value perturbation scheme, could enforce precisely the quantitative results predicted by quantum mechanics. Static EPR causal structures determined retrospectively by key subluminal observers contrast with dynamic EPR causal structures, which involve discontinuities in personal identity. A bilking technique with no analog in traditional accounts of backward causation uses hypothetical tachyon barriers to measure the speed of EPR tachyons.
