They showed a picture of empty space as proof. Yup, a dark galaxy in a dark background. Hmmm... Are they going to call it "The Emperor's New Galaxy"?

Arnik,

What part of the discoverers' methodology don't you understand?

Hi, Arnik---

From the article:

"It was only visible in radio telescopes, which could detect the radio emissions from neutral hydrogen gas located in the cloud."

This shows the basic outline and structural parameters of the dark galaxy, as shown by the red lines.

There ARE all kinds of problems with the whole concept of "dark matter," though. Nobody really seemes to know what it is, so, in a sense, it's "dark" conceptually as well as physically.
