    It is not the case that The label 'time machine' should not be restricted to devices operating within a finite spatial range, because adopting a more liberal stance avoids various complications while still sufficing to elicit key points about time machines.

    Reasons For

    2 perspectives
    Reason for 1 of 2
    ?
    • 1.A definition that permits infinite spatial spread conflates time machines with global spacetime topology changes, obscuring the causal agency of a localized device.
      ?

      Think about whether this reason is strong or weak

    • 2.Earman, Smeenk, and Wüthrich's analysis requires that a time machine's compactly generated Cauchy horizon be traceable to a bounded region, grounding causal responsibility in a finite source.
      ?

      Think about whether this reason is strong or weak

    • 3.Permitting unbounded spatial influence dissolves the distinction between a device causing closed timelike curves and a spacetime that merely happens to contain them.
      ?

      Think about whether this reason is strong or weak

    Reason for 2 of 2
    ?
    • 1.Pragmatic convenience in avoiding definitional complications is insufficient justification when the complications themselves encode physically meaningful constraints.
      ?

      Think about whether this reason is strong or weak

    • 2.The finite-range restriction reflects the requirement that a time machine be an intervention in spacetime, not merely a description of it, a distinction central to interventionist accounts of causation from Woodward onward.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    Reason against
    ?
    • 1.Restricting 'time machine' to finite spatial range introduces various complications.
      ?

      Think about whether this reason is strong or weak

    • 2.A more liberal stance (allowing infinite spatial spread) still suffices to elicit key points.
      ?
