You want to know how really fucked up it is?

If intergalactic space expands, why doesn't the speed of the light crossing it increase proportionally, in order to remain Constant?

Two metrics are being derived from the speed and spectrum of the same light.

Given it is an expanding space and not tired light theory, the speed is still the denominator.

Apparently one way light does redshift over distance, is as multi-spectrum packets, since the higher frequencies dissipate faster. That would mean they are sampling a wave front and the quantification of light is an artifact of its detection and measurement. A loading, or threshold theory.

If this is so, possibly the James Webb might be finding evidence of ever further galaxies. No?
