    It is not the case that The weakened adjacency requirement phrased in terms of timelike curves rather than causal curves is too weak to adequately characterize time machine spacetimes.

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.The (1+1)-dimensional Deutsch-Politzer spacetime satisfies the weakened requirement, since every past endless timelike curve emerging from its time travel region meets Σ₀.
      ?

      Think about whether this reason is strong or weak

    • 2.Deutsch-Politzer spacetime is not a plausible candidate for a time machine spacetime.
      ?

      Think about whether this reason is strong or weak

    • 3.Up to and including time Σ₀, Deutsch-Politzer spacetime is identical with empty Minkowski spacetime.
      ?

      Think about whether this reason is strong or weak
