Mysterious Dark Matter Blob Confounds Experts

mayberry42 writes "Astronomers using the Hubble Space Telescope are mystified by a merging galaxy cluster known as Abell 520 in which concentrations of visible matter and dark matter have apparently come unglued. A report on the Hubble observations, published in the Astrophysical Journal, raises more questions than answers about a cosmic pile-up that's occurring 2.4 billion light-years away. 'According to our current theory,' says Arif Babul, the study team's senior theorist, 'galaxies and dark matter are expected to stay together, even through a collision. But that's not what's happening in Abell 520. Here, the dark matter appears to have pooled to form the dark core, but most of the associated galaxies seem to have moved on.'"

I'm pretty sure this headline is about my recent visit from the plumber.

Move on

[oldhack]

The galaxies are gone. Horse has already left the barn. Spilled milk. Water under the bridge.

Dark matter needs to buck up, get it together, and move on, get on with the life. There is a whole universe out there.

Awoken

Awoken the Grue has been.

Oddly enough, The Fifth Element is on right now

Make sure to call me if that blob starts moving towards earth!
