Re: The important thing the cosmologists have overlooked ...
A very very slight chance (IMO) that things like the discovery of quantum time propagation (quantum superposition effects over temporal systems) may show that a tiny tiny affect in the quantum calculations, adds up to a massive one in say, something like Redshift.
And thus, their calculations are "correct", but they are missing the cause, some tiny mathematical consideration, that makes it all fit together (as Einstein did with relativity/speed of light and Mercury's orbit).
