    Simpler physical processes, such as the propagation of light waves, would be preferable to rigid rods and clocks as indicators of the metric field.

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.Rigid rods and clocks play an indispensable practical role as indicators of the metric field.
      ?

      Think about whether this reason is strong or weak

    • 2.Simpler processes are preferable for indicating the metric field when available.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    2 perspectives
    Reason against 1 of 2
    ?
    • 1.Light propagation presupposes the very metric structure it is meant to indicate, making it epistemically circular as a foundational indicator.
      ?

      Think about whether this reason is strong or weak

    • 2.Reichenbach's conventionalist analysis shows that light-based metric determination requires prior coordinative definitions that are no less conventional than rod-and-clock stipulations.
      ?

      Think about whether this reason is strong or weak

    Reason against 2 of 2
    ?
    • 1.Eddington argued that material rods and clocks, being composed of matter governed by field equations, are self-authenticating probes of the metric in a way that wave propagation, requiring medium-independent assumptions, is not.
      ?

      Think about whether this reason is strong or weak

    • 2.Simplicity of a physical process does not entail epistemic priority if the simpler process depends on more theoretical assumptions to yield metric information.
      ?

      Think about whether this reason is strong or weak

    At first glance it might be surprising that according to the purely close-action geometry, length transfer is non-integrable in the presence of an electromagnetic field. Does this not clearly contradict the behaviour of rigid bodies and clocks? The behaviour of these measurement instruments, however, is a physical process whose course is determined by natural laws and as such has nothing to do with the ideal process of ‘congruent displacement of spacetime distance’ that we employ in the mathemat
