https://en.wikipedia.org/wiki/4C_+37.11>if one black hole of a supermassive black hole binary evaporates, would the remaining black hole be thrown in a straight line through space?Aren't you thinking in slightly linguistically biased terms here? "Evaporate" is commonly used to refer to something disappearing almost instantly, as if becoming nothing more than a vapour, filling the air. But the physical reality here is just an exceedingly slow trickle of matter / energy away from the black hole.
Of course, that's a much slower process than the decay of gravitational systems, but we can ignore that for a moment and imagine two heavy objects in a perfectly stable orbit, which would otherwise spin around each other for eternity.
Now, if we steadily decrease mass from one of these objects, what will happen?
Well, I'm not terribly qualified to answer, but as far as I understand it will continue to orbit (and there are examples of this in our Universe.)
If we decrease the mass of both objects the situation is a lot more interesting, and certainly at some point both will either fly free or collide. Perhaps someone else can chime in?
