Which Came First -- the Black Hole or the Galaxy?

Which Came First -- the Black Hole or the Galaxy?

It almost sounds like the beginning of a corny joke -- Something like why did the black hole cross the galaxy... Because it wanted to get to the other side. But it is no joke. Researchers are now really asking themselves which came first, the supermassive black holes at the center of the galaxies or the enormous galaxies where the black holes reside? A brand new scenario has emerged from a recent set of observations: Black holes may actually be “building” their own home galaxies. This could be the long-sought missing link to understanding why the masses of black holes are larger in galaxies that contain more stars.

The center of mass or center of gravity of any system need not contain much of anything; we see this in binary star systems.

I am kind of surprise, that from one observation scientist made a generic decision about how galaxies are formed.<br>Probably they spent lots of time to analyze it, but I would not trust a theory based only on one observation...<br>Basic induction method requires at least confirmation for 2 observations (n and n+1).<br>Science is turnd inside out!<br>Why they do not consider it as special condition or special case, since this is the only one quasar with such condition (for time being)?
