I'm not getting drawn in into that crank theory.

Is this one the start of a new galaxy, or is it the demise of an old
galaxy?


It could be both, see my discussion with Herb. I listed a hypothesis
that this blackhole may have anchored a far bigger galaxy at one time,
but then it got kicked out and is now just anchoring this left-over
remnant of stars.

You could be right about that of a black hole capturing a galaxy of
stars, though not without considerable collateral damage.

Clearly not true for Dark Matter. Dark Matter will / does have a contribution from MACHOS (inclusive of black holes), WIMPS (however unlikely from many other recent observations), unexpectedly ionized normal matter, and whatever is left some exotic stuff.

The black holes cannot have consumed much normal matter, or Dark matter will have been seen to increase.

Well hardly anyone talks about Dark Matter as MACHOs, but most people
think of WIMPs as being Dark Matter.

Not true. The problem is one of falsification. We cannot falsify MACHOs, as we are discovering more and more, yet we cannot quantify that well, since we would have to be local to a signficant amount, and we realized we are in an area of the Milky Way that is swept pretty clear.

but most people think of WIMPs as being Dark Matter.


Also not true. It is just that there are observations that can be made that allow us to limit or falsify WIMPs. The noise is made on WIMPs, because the streetlight of current capability shines on this possibility.

Mainstream streetlighting upon those interpretations that please their
status quo, as such can't be easily avoided.

"A new scientific truth does not triumph by convincing its opponents
and making them see the light, but rather because its opponents
eventually die, and a new generation grows up that is familiar with
it." / Max Planck

In this case, WIMPS as a Dark Matter candidate can be disproved. So the research money can go there.

- Anomalous amounts of cold neutrinos,
- excessive amounts of MACHOs,
- excessive amounts of ionized normal matter,
- correcting bad spiral galaxy accounting, and of course
- actual exotic Dark Matter
.... will require more work. Death of WIMP proponents isn't really required for these.
