Tooth Fairies Maintaining Galactic Clusters

In Astronomy 2010 wall calendar for February, is pictured a nice image
of a galactic cluster. The text portion says that since galactic
clusters could not have held together for billions of years, then
something like "Dark Matter" - i.e., The Tooth Fairy* - must hold them
together. It then goes on to show how the particular cluster pictured
shows particular evidence, supposedly, of "Dark Matter."

There are going to be more and more anomalies like this in
astrophysics; there are an awful lot of them, already. The Tooth
Fairies are in demand - no unemployment in THAT field!
