    And yet you said that a metre bar would be larger yet measure the same. If all the aspects of the universe are expanding in lockstep such that any distance appears constant, then redshift caused by expansion is impossible.

    If the increasing distance between atoms is unmeasurable, then so too must be the increasing distance between galaxies be undetectable.

    LIGO can detect changes of distance on the order of 10⁻²¹, and it should be increasing in effective length by 2×10⁻¹²m/s, yet I don’t see any mention of any large interferometer measuring anything but gravitational waves, and I don’t see any large time-dependent components of LIGOs systemic error data.

    We also can measure the increasing distance of galaxies via redshift, so unless you can explain how light from galaxies is different from the light in a large interferometer, I must conclude that the interferometers aren’t expanding at the same rate as the observed expansion of the universe.

    We aren’t expanding like the universe is expanding.
