    It is not the case that Kretschmann's point establishes that any physical law can be reformulated in a generally covariant form, making coordinate-invariant impossibility claims suspect.

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

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.Covariant reformulation is trivial (adding dummy variables); it doesn't show theories with different physical content are equivalent or both possible.
      ?

      Think about whether this reason is strong or weak

    • 2.Some impossibility claims concern causal structure or symmetry principles, not coordinate choice—these survive covariant reformulation unchanged.
      ?

      Think about whether this reason is strong or weak

    • 3.Kretschmann conflates 'expressible covariantly' with 'physically realizable'; mathematical elegance doesn't alter what nature permits or forbids.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    1 perspective
    Reason against
    ?
    • 1.Mathematical reformulation in covariant form doesn't require physical change, so covariance alone cannot establish physical possibility or necessity.
      ?

      Think about whether this reason is strong or weak

    • 2.Many impossibility claims rely on coordinate-dependent formulations; Kretschmann shows we must distinguish mathematical from physical constraints.
      ?

      Think about whether this reason is strong or weak

    • 3.If any law admits covariant reformulation, coordinate-specific 'impossibility proofs' beg the question by assuming a particular formalism matters physically.
      ?

      Think about whether this reason is strong or weak
