Hubble Constant Using a Lens

the post:

New measurement of hubble constant adds to cosmic mystery

my comment:

This study will be wrong.

excerpt ===
Graduate student Geoff Chen, Fassnacht and colleagues looked at light from extremely distant galaxies that is distorted and split into multiple images by the lensing effect of galaxies (and their associated dark matter) between the source and Earth. By measuring the time delay for light to make its way by different routes through the foreground lens, the team could estimate the Hubble constant.

my comment:
These are impressive pictures of galactic rings!
Images of the two rings are real rings with real quasars on them. The left one has symmetry but not the right one. They are not a thin circle from a point source bent into a uniform circle around the lens; these rings have width with spaced objects. Haltop Arp observed quasars with about the same red shift were in pairs on opposite sides of an active galaxy between them.

The rule for rings was set by Hoag's object (in Wikipedia's topic) which is a ring galaxy:
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.
Both are clearly rings with active nodes on the ring. These are not lensed objects!

Look at an image of Hoag's Object, Cartwheel Galaxy,  or Lindsay-Shapley Ring, or RXJ1131-1231

For this study the ring and the quasars on the ring are just as observed, not a distortion.

my comment:
They assume these individual nodes are duplicates so any differences are expected only in the light propagation time. In reality they are individual objects which will have their own unique variations.

They are making the mistake of trying to assign differences to a complely wrong cause.

With mistakes like this of course different attempts at measuring hubble's constant can never agree.

It might provide a hint to a possible new physics beyond the current understanding of our universe.

my comment:
These are not lensed systems so their 'new physics' will be wrong.

To propose gravitational lensing by the curvature of spacetime violates physics.
Spacetime is the observer's 4-D space so moving to a coordinate is affected by the curvature. This observer is using their coordinate system for motion.
Light never moves to a coordinate. It always travels in a straight line in a vacuum, never affected by any coordinate system. This is not physically possible.
The one exception is diffraction where the diffraction index of the medium can slow or bend light like a glass prism.
The 1919 solar eclipse test was precisely at the solar limb for maximum diffraction in the solar atmosphere. Stars not at the limb were not affected as expected by a theoretical coordinate system curvature because their path was not diffracted and the curvature did not apply to light.
