"The ratio of visible to dark matter is no longer 1 in 10,000 but one in 300 ... DF44 is not extraordinary." "... not way outside the normal value ..."

Strange, I've never seen 99.7% DM called ordinary.

I always wonder if dark matter doesn't exist and it's just hard to measure the mass of stuff very far away.

Well it's essentially just a placeholder name for what we don't know ;P

Along a similar vein, I find the concept of "Dark Energy" really hard to swallow. To me it seems like such a bizarre assumption to assume a force akin to anti-gravity instead of assuming plain old gravity.
