 Was there any connection between the two? What Magorian discovered was completed unexpected. 

 

The relationship that we find was essentially¹ that the bigger the galaxy², the bigger the black hole. That's in its broad terms. If you want to be a bit more precise about it, we find that the mass of the black hole was very strongly related to the mass of the extraneous³ galaxy. There is a nice linear relationship between these two, with the mass of the black hole being around by half a per cent of the mass of the whole galaxy. 

 

The relationship Magorian had discovered between galaxies⁴ and the tiny black holes at their centre, seems so strange and odd, that Magorian and his colleagues thought that they'd made a mistake. It was like suggesting that something as tiny as a coin could control something as massive as the earth. 

 

When we discovered this correlation⁵ betweeen black hole mass and galaxy mass, we were surprised. Then immediately followed by nervousness. The nervousness then started to give way to possible mine relation that we've discovered something new and fundamental. 

 

That correlation became known as the Magorian relationship and it did indeed point to something profound. 

 

This is incredibly important cause it really meant that there were something linking these tiny super massive black holes from centre of the galaxies with the whole galaxy itself. It meant that somehow their whole history have been intertwined with the growth of the galaxies and the growth of the black holes are somehow related.
