Dear Dr. Minchin,

VIRGOHI 21 may not be caused by any "massive object" whatsoever, as
suggested in my email from Tue, 09 Aug 2005 00:16:53 +0300. Perhaps you and/or some of your colleagues may wish to consider an
alternative hypothesis at

Dear Dr. Minchin,

May I ask you and your colleagues to accept my congratulations on the discovery of the first dark galaxy. I learned about it from CNN,

and read today your astro-ph/0508153 v1 [Ref. 1]. I would like to
comment on one crucial point: the presumption that you've discovered an effect of some "massive object".

It seems to me that the cold "dark" matter effect could have a
completely different origin, that is, a holistic effect of 'potential

The idea is a bit complicated, since it includes the other "dark"

BTW there are amazing "dark" effects in the human brain as well, in the sense that nobody has discovered some "dark" computer that could correlate nearly 100 billion neurons. Perhaps the holistic effect of 'potential reality' produces different "dark" effects at the scale of galaxies: something has to keep them together and stay "dark", only it may not be 'massive object' at all, since it may not contain any mass whatsoever.

I will be happy to elaborate, of course.

Kindest regards,

Dimi Chakalov

"Since it apparently contains no stars it must have *and must always have had*, ten times less baryons -- a phenomenon often apparent in dwarf galaxies (Mateo 1998). Thus 90 per cent of the baryons one might have expected to find in a typical galaxy appear to be missing. Whatever the reason, the lack of baryons in such massive objects can only decrease their detectability.

"The new observations make it even harder to escape the inference that VIRGOHI 21 contains a massive dark disc."

Dear Drs. Taylor and Webster,

In your recent article "On Star Formation and the Non-Existence of Dark Galaxies" (astro-ph/0501514 v2, accepted for publication in ApJ), you posed the question "whether a dark galaxy, having formed, can remain dark, or whether it will inevitably ‘light up’."

I'm afraid we don't know the mechanism of formation of any clump of dark matter. If you agree, please see my proposal for a perfectly "dark" galaxy at

It can never ‘light up’ because it contains no *real* matter whatsoever.

More on these "dark" effects (in the context of GW astronomy) can be read at

Your comments will be highly appreciated.

Dear Dr. McGaugh,

I am VERY happy to read your paper [Ref. 1]. Thank you! Don't you think that the "dark" matter is really smart as well? [Ref. 2] Please see also

[Ref. 1] Stacy S. McGaugh, The Balance of Dark and Luminous Mass in Rotating Galaxies, astro-ph/0509305 v1.

"We still know very little about the nature of the dark matter (presuming it exists). It may possess some property that imparts the observed balance with baryons in galaxies. This idea implies a specific interaction between the two that is in some way repulsive: the greater the surface density of baryons, the less that of dark matter."

[Ref. 2] Philip D. Mannheim, Alternatives to Dark Matter and Dark Energy, astro-ph/0505266 v2.

"Dark matter thus seems to know where, and in what amount, it is to be needed, and to know when it is not in fact needed (dark matter has to avoid being abundant in the solar system in order to not impair the success of standard gravity in accounting for solar system observations using visible sources alone); and moreover, in the cases where it is needed, what it is actually made of (astrophysical sources (Machos) or new elementary particles (Wimps)) is as yet totally unknown and elusive."

Dear Dr. Foot,

I very much like your web site,

and your conjecture about the anomalous slow-down of *both* Pioneer spacecraft (astro-ph/0407623 v1, p. 25). It is still a mystery [Ref. 1].

I wonder if you can "attach" a mirror galaxy to VIRGOHI 21,

[Ref. 1] Strange attraction, by Marcus Chown. New Scientist, 20 July 2002.

The veteran spacecraft hurtles towards the stars. Out at the darkest
edge of the Solar System, far beyond Pluto, there should be nothing but the feeble gravity of the receding Sun to slow it down. Yet a mysterious extra force seems to be tugging on the spacecraft. And 24 billion kilometres away in the other direction, the probe's twin is feeling an identical force.

Pioneers 10 and 11 may be old and battered, but in their twilight years they are giving physicists a few sleepless nights. The probes were launched in 1972 and 1973, and Pioneer 10 became the first spacecraft to fly past Jupiter. Pioneer 11 followed it past Jupiter and then became the first to visit Saturn. "After those encounters, we thought that essentially the mission was over," says astronomer John Anderson of NASA's Jet Propulsion Laboratory (JPL) in Pasadena. "How wrong we were."

Dear Dr. Anderson,

I quoted your statement regarding the Pioneer Anomaly at

Note: There should be two kinds of "dark" effects: implosion, as in the case of the cold dark matter, and explosion/expansion, from the dynamic dark energy. I speculate that these effects are "remnants" from the Holon, and are residual forces pertaining to every spacetime "point", as mentioned here. More on the dark energy here; notice also the book by Yakov Terletsky here.

Dear Dr. Siewert,

I read with great interest your gr-qc/0610034 v2 and, given your conclusion and that of your colleagues ("currently, we find no mechanism or theory that explains the anomalous acceleration", J.D. Anderson et al., gr-qc/0104064 v5), may I draw your attention to my efforts at explaining the "dark" effects of geometry at

I speculate about two opposite forces producing the effects known as "dark" matter and "dark" energy, such that the observed blueshift in the Pioneer signal may be of of cosmological origin, caused by the "dark" matter effect,

Should you or your colleagues have questions, please don't hesitate to write me back.

Hi Lorenzo,

But I'm talking new physics here. Your statement is from 1915, and tallies to 4 % from the stuff in the universe.

Sure will. However, the hypothetical "dark matter"-like effect is both scale and mass dependent, so its blue-shift impact on Pioneer satellites was much stronger due to their smaller mass.

> I did not yet find them.

And never will. This is the beautiful part from your gr-qc/0610050 v3 IMHO.

Did you make the effort to click on the link from my preceding email? The
putative "dark matter"-like effect can create a whole "dark" galaxy. Try to
fit it into GR textbooks, please!
