A second support for inertia less dark matter black holes is:
the denial of dr. Zumalacárregui ( Berkely https://lnkd.in/gzD6eW6 ) he said about the missing lensing effect in Supernovas, as support for the Black Hole - Dark Matter relation DENIAL.
However if black holes leave the implosion site as soon they are born, then there is NO lensing effect observed !!

An other evidence that black holes and even neutron stars have reduced inertia they do not rotate before merging.
They seem to have no inertia enough to rotate around each other before merging longer than a second. ( see image below.)
My conclusion is that they do not rotate but simply BANG into each other, with only deformation gravity wave effects
Based on my non-rotation postulate:
I assume this as an extra support that black holes and neutron stars have reduced inertia.
Secondly, that black holes is the same as dark matter.
Neutron stars could harbor lots of micro black holes just as sunspots re supposed to represent.
( according to Quantum FFF Theory)
Then, an interesting example of dark matter / black holes without inertia effects is to be found in two merging galaxy clusters.
The merging Bullet cluster and Abell 520 cluster, show gas producing dark matter black hole concentration in between, accelerating in front out of the clusters, due to lack of inertia/ mass.
see images above.
Evidence for New Physics of Dark Matter= Black Holes. There is dark matter space curvature, due to vacuum dark energy (Casimir) effect forming DM-BH peaks, however there seems to be NO Inertia or normal Mass effect.
As a result of no inertia, the dark matter black hole content of the merging cluster Abell 520, showing unnatural acceleration and concentration in between three clusters
