That's pretty cool, but I don't get the beach ball comparison? It's basically just a flattened sphere so why resort to the comparison of a beach ball in particular? Do the red, white and green colours represent anything (i.e. relative concentration of dark matter in those areas) or was it just placed there for people who can't picture a beach ball?

Why don't they just call it ball-shaped or spherical? Beach-ball-shaped is a little bit redundant, like saying "It is the colour of a car that is red."

Yeah the colours are to represent the ball.

OMGGGGGGG. MAYBE DARK MATTER IS LIKE... GOD. THAT'S WHY WE CAN'T SEE IT, BUT IT'S ALWAYS THERE!!!! ZOMG MY RELIGION WINS.

I figured that I would get that in just in case someone tried to say it. I've heard that "argument" in previous experience.

So when are we harvesting the dark matter for the death star?

As soon as we find a planet of Nibblers so we can farm their feces. :)

That's pretty stupid of whoever did that. Trying to appeal to the lowest common denominator I suppose.

The whole exercise is a little bit silly. All they have done is mapped gravitational pull. Saying it's dark matter is akin to saying it's flurble. Dark matter is a placeholder term for we don't know what the heck is really happening or what it is.
