The amount of Dark Matter in a spiral or other galaxy, is inferred by assuming the central stars are "normal", so the mass of a region is proportional to the luminosity of that region. Regardless of whether or not that region contains a supermassive black hole. Then this same scaling factor is applied across the rest of the galaxy, ignoring the mass-luminosity relationship of the HR diagram. No, it is based on increasing mass in regions where is no significant mass. BTW, "visible shining baryonic mass is just about 1/4 of total baryonic mass. Note that there is at least 5 reasons to consider dark matter, and at least 3 of lead to very similar quantitative estimations.( galaxy rotation curves, CMB analysis, primary pre-star isotopically universe composition) > > Like as not, Dark Matter is just normal matter, represented by stars that have photospheres (rather than tidally stripped / stretched), individual stars with much less than 20 solar masses (where luminosity is not proportional to mass). Visible matter in stars is just a minor part of total baryonic matter. > > Your description is correct for exotic Dark Matter. But this has failed to show in our solar system, and the assumption(s) described above turn stellar systems exactly like ours into mostly "Dark Matter". It does not failed to show, as it behaves as expected. The Solar system has extraordinary high mean mass density, compared to galaxy mean mass density, including its neighbourhood. -- Libor Striz aka Poutnik ( a pilgrim/wanderer/wayfarer) ----Android NewsGroup Reader---- http://usenet.sinaapp.com/
