Neufer. Your "More of a quadruple bubble actually (but that's not your fault, Dave)." made me
(my bold emphasis on "fault").

Hi,
I'm just an interested person without much knowledge. So please don't hit me if I ask for a connection between this phenomenon and the one described at http://hubblesite.org/newscenter/archiv ... 0/37/full/ .
Couldn't dark matter in the halo of "our" milkyway accelerate intergalactic matter so that it emits gamma-rays? Maybe angular momentum and magnetic fields could explain this?
Sorry, if this question is a dumb one,
Peter

Gravity is far too weak a force to accelerate interstellar matter sufficiently to produce gamma rays. And while the galaxy has a magnetic field, it is very weak, and doesn't visibly interact with matter in a significant way.petsie wrote:Couldn't dark matter in the halo of "our" milkyway accelerate intergalactic matter so that it emits gamma-rays?

Art, my picture is nowhere near as delightful or as appropriate as yours. Nevertheless, I want to recommend the Tintin adventrue Destination Moon and Explorers on the Moon. In one of these books, probably the latter, the hoplessly clumsy and clueless detectives, Thompson and Thomson, accidentally ingest something that makes their hair and beards grow wildly and take on incredible colors. But the two detectives are also blowing bubbles as if they were full of soap, and they are breathing and blowing soap bubbles uncontrollably!neufer wrote:
After a while they stop blowing bubbles, their hair stops growing and starts retreating, and the two detectives go sightseeing on the Moon, where they have a wonderful time. Note the low gravity ballet-like dance steps.
