The real cause of "dark flow"
Sep. 9th, 2009 08:29 pmSomething unseeable and far bigger than anything in the known universe is hauling a group of galaxies towards it at inexplicable speed.
A recent finding by Sasha Kashlinsky at NASA's Goddard Space Flight Center in Greenbelt, Maryland, makes no sense in a universe assumed to be relatively homogeneous. His team has found a group of galaxy clusters moving at an extraordinary speed towards a small patch of sky between the constellations of Centaurus and Vela. Kashlinsky calls it the "dark flow", in tribute to those other cosmic mysteries dark matter and dark energy (New Scientist, 24 January, p 50).
Suggestions as to what is causing this massive attraction are rampant.
