Mysterious 'unparticles' may be pushing the universe apart, new theoretical study suggests

New theoretical research suggests that a mysterious form of matter called "unparticles" could be the driving force behind the expansion of the universe.

While this seems like the substitution of one fitting parameter for another, I think it is a potential step forward in that it tries to produce an equation of state for the new parameter, instead of just using a constant. That potentially allows for theoretical inferences that can be tested, so that an equation of state might be worked out from better data.

It would not surprise me at all if the eventual result is that the expansion of the universe we observe today does not extrapolate back in time all the way to a single point.
