"Dark Flow" of Galactic Clusters Towards a Super Massive Gravitational Attractor.

About 10 years ago scientific community was abuzz with talk of Dark Flow. This was the flow of quite a few huge galactic clusters on a certain vector as if they were being attracted by "something". That supermassive "something" is beyond the visible universe so we will never be able to "see" it and only know of it as a theoretical possibility from the effects of its gravitational attraction. Renewed work confirmed the dark flow with even more galactic clusters included in the second analysis. Now new data regarding the cosmic microwave background (CMB) radiation left behind like an afterglow from the Big Bang will provide a better baseline against which to measure this flow which is still disputed in the astronomical community.

What could be so massive that its gravitational attraction is drawing huge galactic clusters, including our own, from far beyond the 13.8 billion light years distance we can observe in our visible universe?

Sounds like a swarm of supermassive black holes or some form of vacuum. In all likelihood it'll turn out to be something kind of mundane like so. I doubt its aliens, as an extraterrestrial nation-state that powerful (and not to mention of the intergalactic filament-scale **** magnitude) would have yielded at least a minuscule amount of evidence pointing towards its existence as close as the Moon and Mars - ie, we would've seen it by now.

The gravitational attractor is well beyond the confines of the visible universe and thus we will never see what is causing this alleged dark flow. It is moving away from us at a speed greater than the spread of light and thus no electromagnetic energy from this attractor will ever reach us. Some estimates put it at between 46 and 52 billion light years distant so it's gravitational distortion of space time must be huge to effect galactic clusters here, so very far away. The visible universe is roughly a sphere with a radius of 13.8 billion light years so this attractor seems to be about three "visible universes" away from us. Or it could be a parallel universe or one of many in a multiverse. We will likely never know. But man, it must be mindbendingly massive to be sucking our galactic clusters towards it at such an inconceivably long distance over space-time.
