Paul, I thought you might like this quote from New Scientist.

"The universe today is a little like one of those ghost movies. Galaxies whirl around in unexplained ways. Groups of stars race across space, pulled by forces from beyond the visible universe. The fabric of space is inexplicably elastic, expanded ever faster by an inscrutable energy all of its own.

Not an overly superstitious bunch, cosmologists invent names for the poltergeists responsible – dark matter, dark flows, dark energy – and invest a lot of effort in proving they are real. But might they, too, be chasing ghosts?"

There never was nothing.
