Universe Expansion Crisis
The team's results add to growing evidence that there is a problem with the standard model of cosmology, which shows the universe was expanding very fast early in its history, then the expansion slowed down due to the gravitational pull of dark matter, and now the expansion is speeding up again due to dark energy, a mysterious force.

A crisis in cosmology: new data suggests the universe expanding more rapidly than believed
So many points of interest.
1) impressive pictures of galactic rings!
I posted on June 20 about observed galactic rings and arcs. The rule set by Hoag's object: if the galactic ring has knots or structure then the ring cannot be a ring from a distant point light source distorted to be a ring simply because a lensed ring cannot show structure from a distant point.
All of these rings are clearly rings with active nodes on the ring. These are not lensed objects!
The rings and the quasars on the ring are just as observed, not a distortion.
2) measurement techniques cannot get the same result.
measurements thus far are in disagreement.
So, when we are comparing the Hubble Constants that come out of various techniques, we are comparing the early universe (using distant observations) vs. the late, more modern part of the universe (using local, nearby observations)."
This suggests that either there is a problem with the CMB measurements, which the team says is unlikely, or the standard model of cosmology needs to be changed in some way using new physics to correct the discrepancy.
Secondly, we found that combining the AO and HST data gave a more precise result."
Clearly the data sets cannot match their expectation of getting consistent results.
If AO HST data are not consistent then combining 'bad' data sets certainly does not create a 'good' data set.
On August 20 I posted about dark energy analysis requires data manipulation. This story is more of the same confusion.
3) unjustified optimism.
"We can now try this method with more lensed quasar systems to improve the precision of our measurement of the Hubble Constant. Perhaps this will lead us to a more complete cosmological model of the universe," says Fassnacht.
These are not lensed systems so they continue to use data to mislead them to a wrong incomplete model of the universe.
