How Awesome is This
Science is so cool in its own right I don’t know why anyone would prefer religious explanations. Dark flow is the latest dark phenomenon, and I wont pretend that I understand it at this point.
Everything in the known universe is said to be racing toward the massive clumps of matter at more than 2 million miles (3.2 million kilometers) an hour—a movement the researchers have dubbed dark flow.
The presence of the extra-universal matter suggests that our universe is part of something bigger—a multiverse—and that whatever is out there is very different from the universe we know.
The trouble with conceptualizing things like this is nicely described by Dawkins here.
