Considering modern physics has given us string theory and supersymmetry, is it remotely possible this version of cosmology is also not as established as it is presented?

The idea of expanding space comes from General Relativity and spacetime, but if space expanded, wouldn't the speed of light have to increase proportionally, in order to remain constant?

Yet it is assumed the speed of intergalactic light travels some other metric, than this expanding space, which is based on the spectrum of the very same light.

Considering dark matter and dark energy are rather enormous patches, already applied to save this model, wouldn't there be even a tiny bit of hesitancy?

What if your accountant just wrote in a figure and called it dark money, whenever he finds a gap in the books?

It used to be that when observation didn't match prediction, the possibility the theory was falsified was at least considered, but no more. Too many reputations are at stake. Just like string theory.

Epicycles were brilliant math, as description, but the crystalline spheres were lousy physics, as explanation.
