Clusters are streaming at up to 1000 kilometres per second towards one particular part of the cosmos (The Astrophysical Journal Letters, vol 686, p L49).
1400 clusters are part of the flow, and it continues to around 3 billion light years from Earth, a sizeable fraction of the distance to the edge of the observable universe (arxiv.org/abs/0910.4958).
The dark flow appears to have been caused shortly after the big bang (that's what they think!) by something no longer in the observable universe.
Scientists say one explanation for the flow would be the gravity of a huge concentration of matter, but this is very unlikely. Not sure how big they mean, but I reckon the comet we decimated has probably collected to itself a lot of space debris and may well constitute a huge concentration.
Can't help hoping that our stones have somehow returned to this earth - or maybe the Lightbringers have garnered them, ready to use again - for us?
