    It is not the case that The counterexample relies on solutions that are not globally hyperbolic, but Penrose and Hawking's singularity theorems suggest physically realistic spacetimes satisfy strong causality conditions.

    ?Set your confidence on the premises below to see your aggregate.

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.Global hyperbolicity is a sufficient but not necessary condition; weaker causality may hold in realistic scenarios near singularities.
      ?

      Think about whether this reason is strong or weak

    • 2.Penrose-Hawking assumptions (geodesic completeness, energy conditions) may fail in quantum gravity, undermining classical theorems' scope.
      ?

      Think about whether this reason is strong or weak

    • 3.Counterexamples demonstrate mathematical possibility; dismissing them requires independent empirical evidence, not just assumption-matching.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    1 perspective
    Reason against
    ?
    • 1.Penrose-Hawking theorems rigorously derive singularities under causality conditions satisfied by all observed astrophysical systems.
      ?

      Think about whether this reason is strong or weak

    • 2.Non-globally hyperbolic spacetimes lack predictability from initial data, making them physically unrealistic for observable universes.
      ?

      Think about whether this reason is strong or weak

    • 3.Counterexamples exploiting pathological causality violate the generic conditions required by physically justified field equations.
      ?

      Think about whether this reason is strong or weak
