    "abstract": "The closed causal chains arising from backward time travel do not lead to\nparadoxes if they are self consistent. This raises the question as to how\nphysics ensures that only self-consistent loops are possible. We show that, for\none particular case at least, the condition of self consistency is ensured by\nthe interference of quantum mechanical amplitudes associated with the loop. If\nthis can be applied to all loops then we have a mechanism by which inconsistent\nloops eliminate themselves.",
