Super Massive Black Holes and Dark Matter. Given detection similarities : Could galaxy central SM Black holes be concentrated Dark matter.?

"Super Massive Black Holes and Dark Matter. Given detection similarities : Could galaxy central SM Black holes be concentrated Dark matter.?"

First, Dark Matter is matter that is not represented by the luminosity super hot bare stars at the center of a spiral galaxy. So initially, the central black hole is already accounted for in the calibration factor: (total amount of non-Dark mass) / luminosity.

Second, black holes that are NOT at the center of a spiral galaxy, are automatically considered to BE Dark Matter, since they are (in general) Dark (no friction, no representative light emissions).

So, no, by calibration, the central black hole is NOT Dark Matter, even if black holes further out *are*.

Please note that Dark Matter is a mystery envelope, with the following contents"

- brown dwarves, rogue planets, photospheres on stars (makes them cooler, less luminous), dust clouds, nebulae (makes stars contained cooler, less luminous), and black holes;

- calibration errors induced because central core stars *have* no planets, the central core is swept clear of dust; and

- possible mystery matter (WIMPs and so on) that have yet to be seen anywhere in this this galaxy, even though it *must* be passing through this solar system continuously (it also orbits the Milky Way).

If we can see well enough, there is no Dark Matter. So think of Dark Matter more as the old saying at the edge of maps "Here Be Dragons".

There is undoubtedly some Dark Matter that might have fallen into a black hole, but the concentrations of the theorized Dark Matter are too small for black holes to form mainly from dark matter.

No because dark matter does not interact normally with matter. It seems to pass right through matter and it does not get attracted to centers of gravity. Black holes do not form from dark matter but from dense concentrations of matter.

They have little, probably nothing to do with one another. The interiors of black holes and the characteristics of dark matter are mysterious and probably disconnected from one another.

No, from the lensing of light we can show that Dark matter appears to be concentrated in haloes above and below the plane of spin of galaxies - it realy is weir d stuff.

No; we're able to *map* concentrations of Dark Matter; black holes would be point-sources on the map: http://www.space.com/29085-dark-matter-maps-unknow...

we don't know.
