I was indeed wrong to use the word impossible.

Just off hand, M 31, the Andromeda galaxy, has 2 SMBHs near its center that may eventually merge or eject its less massive BH. NGC 4038-39 (the 'Antennae galaxy') contains 2 SMBHs that will eventually merge or eject one of its SMBHs. I fail to see the impossibility of ejection of SMBHs from galaxies given the proper circumstances & no modification of Newtonian gravitational mechanics.

Improbable... yes. To say this is impossible is simply ignorance... given the lack of knowledge we have about SMBH, gravity, magnetism and all affects when two OR MORE (A lot of things change when you have a binary set and an incoming thrid stranger) SMBH's are in the same vicinity; we don't even have enough data to attempt an accurate simulation. We have seen stranger things come true. I do agree however, there has been too much speculation tossed out to the media concerning this and a few other things. The cost of individuals wanting to get ahead and be noticed. IMHO... it is common sense, that if light can be distorted, bent and slowed down, then it is likely gravity can be changed as well.. meaning it isn't constant at all times; thus don't count anything out when it comes to gravity and SMBH. Impossilbe…. no.
Improbable… yes.

I was not aware of them. "Avery Broderick, from the Canadian Institute for Theoretical Astrophysics, examines jets produced by the Milky Way's SMBH and M87"

It is my understanding that any SMBH at the centre of a galaxy is gravitationally attached to the visible galaxy that surrounds it. You cannot move one without the other. For the proposed theory of a gravity kick bouncing one part of the galaxy with gravity waves out of the structure of a galaxy to have credence, you would need a boundary, within the galaxy, where the normal gravitational forces will be at or near zero, effectively disconnecting, gravitationally, one part of the structure of the galaxy from the other. IMHO that is absolutely impossible.
