The problem with this is that the distances they now believe for quasars are based on a host of assumptions. And they assume what a quasar is … they don’t really know. They assume that it’s only distance that causes redshift, even though scientists have now proven there are scores of ways redshift can occur and some of those, plasma cosmologists say, are responsible for much of the redshift observed. They assume that quasars are jets coming from black holes, when in fact plasma cosmologists have offered other explanation for these jets that have not been debunked. In fact, a good case can be made from observations of galaxies and quasars that many high redshift quasars are actually associated with much closer galaxies ... in other words, much closer than their redshift, using the other assumption, would suggest. Halton Arp developed a whole theory about what was in reality happening, which has not been debunked because the observations fit his model, not theirs.Blindingly bright black holes could help cosmologists see deeper into the universe’s past

In recent decades, the gold standard for measuring vast distances has been one variety of stellar explosion: the type 1a supernova. … snip … These so-called “standard candles” have revealed that the universe is expanding faster and faster, implying that a mysterious “dark energy” is driving galaxies apart.
But individual stars, even exploding ones, eventually peter out as astronomers peer deeper into the darkness. With current telescopes, researchers can’t see type 1a supernovae beyond nine to ten billion years ago (because light takes billions of years to reach earth, looking out into space also means looking back in time.) Without any visible supernovae, cosmologists—researchers who specifically study the evolution of the cosmos as a whole—are left largely in the dark as to what went on during the universe’s first four billion years.
A new standard candle
That’s where quasars come in. … snip … Since astronomers can pick out the blaze of quasars during the universe’s first billion years, could these objects serve as brighter, more penetrating standard candles?
Some astronomers believe that they can, thanks to one crucial property. Quasars pump out ultraviolet light, and some of these ultraviolet rays smash into a surrounding cloud of hot electrons, unleashing higher energy X-rays. Because the ultraviolet light makes X-rays in a predictable way, a quasar’s X-ray brightness is tied to its ultraviolet brightness in a fixed manner, no matter how far away the galaxy is. By comparing the ultraviolet and X-ray emissions with how bright or dim a quasar appears overall, astronomers can use it as a cosmic mile marker.
The mainstream's model is truly a house of cards waiting to collapse.
