What if accountants worked like cosmologists? When the books don’t add up, just insert a figure and call it Dark Money.
The fact is that falsifiability doesn’t apply to cosmology.
One of the original patches to Big Bang Theory was when they realized this redshift was identical in all directions, creating the effect that we appear to be at the center, it was changed from an expansion in space, to an expansion of space, based on Spacetime! Totally ignoring the essential premise that the speed of light remains constant to the frame, because if the light is being redshifted, obviously it is not Constant to intergalactic space. What is the speed of this light measuring, if not intergalactic space? Two metrics of space are being assumed, based on the very same light. One on the spectrum and one on the speed. The inchworm and the expanding balloon are both derived from the same light. It doesn’t add up.
Now we are at the center of our point of view, so a logical conclusion might be that cosmic redshift is an optical effect.
For example, it has been shown that multispectrum light “packets” do redshift by distance alone, as the shorter wave lengths dissipate faster than longer wave lengths, yet that would question whether the quantization of light is fundamental, or an effect of measurement. That what we observe is a sampling of a wave front, not individual photons traveling billions of lightyears.
Maybe waves are not just mathematical constructs, but actual, physical dynamics.
Cosmology tried patches before, with epicycles.
