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

The black holes cannot have consumed much normal matter, or Dark matter will have been seen to increase. David A. Smith Well hardly anyone talks about Dark Matter as MACHOs, but most people think of WIMPs as being Dark Matter. |

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. David A. Smith |

Dear Brad Guth:

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