Explanation: What happens when two black holes collide? This extreme scenario occurs in the centers of many merging galaxies and multiple star systems. The featured video shows a computer animation of the final stages of such a merger, while highlighting the gravitational lensing effects that would appear on a background starfield. The black regions indicate the event horizons of the dynamic duo, while a surrounding ring of shifting background stars indicates the position of their combined Einstein ring. All background stars not only have images visible outside of this Einstein ring, but also have one or more companion images visible on the inside. Eventually the two black holes coalesce. The end stages of such a merger is now known to produce a strong blast of gravitational radiation, providing a new way to see our universe.

Apparently, math supports that this causes a distortion in the fabric of space-time that allows for backwards time travel.

OJ 287 is a supermassive black hole with a mass equal to 18 billion suns. Orbiting it is a "small' black hole of 'only' 150 million solar masses. (The Black hole at the center of our galaxy is 4.2 million times the mass of the sun).
It got the attention of Astronomers because twice every 12 years it got a trillion times brighter in a seemingly random way. The latest flare up was predicted to within 15 minutes of when it happened again. It's orbit actually makes a Rosetta pattern predicted by General relativity. An animation of that orbit is right here.

OJ 287 is a supermassive black hole with a mass equal to 18 billion suns The scale of the universe boggles my mind. The complexity of DNA is on the same scale. All of this happening by chance? Absurd

Noted that that the rotation was counter clockwise, does this mean the two galaxies were in the Southern Hemisphere of the Universe?
s/.
I guess that if one is viewing from the other side of the drain, then it would be clockwise. Much like what that cockroach looks up to see as you flush it down

And if somehow these two black holes were viewed from the opposite side, would they not be rotating clockwise?
