    Phase differences predicted by Weyl's theory (with the -i factor) are physically measurable, as demonstrated by interference experiments with electrons.

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.Measuring a phase difference requires an interference experiment.
      ?

      Think about whether this reason is strong or weak

    • 2.Interference experiments cannot be performed with macroscopic objects like clocks.
      ?

      Think about whether this reason is strong or weak

    • 3.Interference experiments can be performed with electrons.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    2 perspectives
    Reason against 1 of 2
    ?
    • 1.Electron interference experiments measure relative phase differences, not the absolute gauge phase introduced by Weyl's U(1) factor.
      ?

      Think about whether this reason is strong or weak

    • 2.Weyl's original 1918 theory posited spacetime-path-dependent scale changes, whereas quantum mechanical phase is a distinct mathematical structure with different physical interpretation.
      ?

      Think about whether this reason is strong or weak

    • 3.The empirical success of quantum electrodynamics vindicates London's 1927 reinterpretation of Weyl's gauge idea, not Weyl's original metrical theory, making the inference from interference experiments to Weyl's specific claim underdetermined.
      ?

      Think about whether this reason is strong or weak

    Reason against 2 of 2
    ?
    • 1.The Aharonov-Bohm effect, often cited as confirming gauge-phase measurability, demonstrates that physically meaningful phase differences arise from electromagnetic potentials, not from Weyl's spacetime geometry.
      ?

      Think about whether this reason is strong or weak

    • 2.Conflating the empirical confirmation of U(1) quantum phase with confirmation of Weyl's geometrical gauge principle commits an equivocation between formally similar but physically distinct theoretical structures.
      ?

      Think about whether this reason is strong or weak

    Apparently no one had, after 1929, relooked at Einstein’s objection until I did in 1983. The result is interesting and deserves perhaps to be a footnote in the history of science: Let us take Einstein’s Gedankenexperiment …. When the two clocks come back, because of the insertion of the factor \(-i\), they would not have different scales but different phases. That would not influence their rates of time-keeping. Therefore, Einstein’s original objection disappears. But you can ask a further
