A runaway supermassive is even moreso.

Like, what the absolute fuck could have happened to give the core of a galaxy that much velocity?

We're assuming the black hole is moving, when we could be the ones moving and it is stationary. Movement is relative, and we always assume it from our own perspective.

But if it's stationary and we're moving at 2.2m mph...

Yeah, even scarier. =D

I'd assume two galaxies merged, and the black hole from one got a gravitational slingshot from the other. The result of that passing near, or through, another galaxy would be fascinating to study. From a very, very, long way away.
