    It is not the case that If the guiding field is fully determined by the metric, and the metric is determined by mass-energy via Einstein's equations, then 'dynamic' privileging collapses into Machian relational dependence, not absolute motion.

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.Diffeomorphism invariance permits multiple metrics for identical matter distributions; metric underdetermination blocks reduction to relational facts alone.
      ?

      Think about whether this reason is strong or weak

    • 2.Spacetime can support non-trivial solutions (Kerr-Newman vacuum) without matter; geometry retains independent causal power incompatible with pure relationalism.
      ?

      Think about whether this reason is strong or weak

    • 3.Frame-privileging in rotating frames reflects genuine physical asymmetry (geodesic deviation), not merely relational structure—absolute rotation exists.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    1 perspective
    Reason against
    ?
    • 1.Einstein's equations establish metric as sole gravitational degree of freedom; no independent geometric structure exists apart from matter.
      ?

      Think about whether this reason is strong or weak

    • 2.If all physical facts supervene on mass-energy distribution, then privileging any frame requires asymmetry in that distribution, not absolute space.
      ?

      Think about whether this reason is strong or weak

    • 3.Mach's principle predicts exactly this: inertial frames determined relationally by cosmic mass distribution, not by empty spacetime structure.
      ?

      Think about whether this reason is strong or weak
