Subject: Does VIRGOHI 21 contain
any massive object?
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, http://www.cnn.com/2005/TECH/space/02/24/dark.galaxy/ and read today your astro-ph/0508153 v1 [Ref.
1]. I would like to
It seems to me that the cold "dark" matter effect could
have a
http://www.God-does-not-play-dice.net/Landsman.html#note_last The idea is a bit complicated,
since it includes the other "dark"
http://www.God-does-not-play-dice.net/dark_energy.html 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
Reference [Ref. 1] R. F. Minchin et al., A Dark Galaxy in the Virgo Cluster Imaged at 21-cm, astro-ph/0508153 v1. "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." ==================== Subject: On Dark Galaxies
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 http://www.God-does-not-play-dice.net/Minchin.html 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 http://www.God-does-not-play-dice.net/Price.html#note http://www.God-does-not-play-dice.net/download.html Your comments will be highly appreciated. Regards, Dimi Chakalov ===== Subject: The Balance of Dark and Luminous Mass
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 http://www.God-does-not-play-dice.net/Minchin.html Best regards, Dimi Chakalov
[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."
=========== Subject: Mirror "dark" ...?
Dear Dr. Foot, I very much like your web site, http://www.ph.unimelb.edu.au/~foot/ 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, http://www.God-does-not-play-dice.net/Minchin.html My efforts to approach the "dark" matter can be read at http://www.God-does-not-play-dice.net/Rosinger.html Best regards, Dimi Chakalov

at the darkest
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."
======== Subject: "How wrong we were."
Dear Dr. Anderson, I quoted your statement regarding the Pioneer Anomaly at http://www.God-does-not-play-dice.net//Minchin.html#F1 More at http://www.God-does-not-play-dice.net/Rosinger.html http://www.God-does-not-play-dice.net/Khrennikov.html#Belavkin Regards, Dimi Chakalov
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.

================== Subject: A constant bias directed
*toward* the Sun
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 http://www.god-does-not-play-dice.net/download.html 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, http://www.god-does-not-play-dice.net/Minchin.html#F1 Should you or your colleagues have questions, please don't hesitate to write me back.
