NO GIANT black hole inside the Galaxy center? Can I explain to cycles scientist what this discussion has to do with cycles? YES.
The mainstream ideas about a Giant Milky way- central black hole are lately firmly supported by clear stellar acceleration profiles around the Sagittarius A cluster, see:
http://www.einstein-online.info/en/spotlights/milkyway_bh/index.htmlHowever according to new combined Hubble images of the Sgt..A area there is no sign of any gaseous filamentary Vortex or elliptic structure.
Instead we see more than one clear elliptic filaments around the three stellar clusters called: Sagittarius A, Quintuplet and Arches cluster.
This seems to be a tell tale for more than one (at least three) barycentres as the origin of these open star clusters.
My conclusion based on a new interpretation of black hole splitting and paring
The center of the Milky way is supposed to be equipped with several medium sized DUAL black holes (BHs) forming circular visible gas filaments (elliptic trails) and in the barycenter in the middle between dual black holes: open star clusters like Sgt A, the Quintuplet and Arches cluster. Conclusion: there is NO Giant Black hole in the center of our galaxy.
http://migratingblackholes.blogspot.com/2009/01/milky-way-centre-no-giant-black-hole.htmlMy model is leading to NEW black holes different from the mainstream interpretation by the introduction of a thin black hole horizon shell of fermion repulsion, leading to dual systems of black holes at all scales with gas formation in the bary center ( the middle)
