I know that this can not be true because if it was, the universe would be mainly black hole by now but I can't seem to fathom how if something has an increase in mass (law of conservation of mass) from an external object, it does not increase in size.
My next thought would be, if gravity is proportional to mass (growth or not in size), then the more massive the black hole becomes, the greater effect that gravity would have on surrounding stars etc and then a theory popped into my head.
Considering that the Milky Way has a SMBH at its centre, the galaxy would, through growth in mass and therefore gravity of the SMBH, it will eventually draw in the outer spiral arms in toward the middle thus forming an eliptical galaxy akin to M87. This then would explain the lifecycle of a galaxy from rotating spiral to rotating eliptical to eventually nothing.
I don't know - my name is not plainstupid for nothing.
