“It’s a little weird in current dark matter models..”

Milky Way Dark Matter SurveyWe might not know exactly what dark matter is yet, although the world’s highest-energy particle accelerator is the most likely experiment to provide evidence for the answer to that question, but we can still see the effects of its existence.

What came out is what Dr [David] Law described as a “cosmic beach ball, squashed from the side”, flattened along the direction corresponding to the plane of the Milky Way. The fact that the un-flattened direction should be above and below the galactic plane remains a mystery. “It’s a little weird in current dark matter models, but it’ll be very useful in helping constrain future models, not only of dark matter itself but also how galaxies such as our own form in the universe.
