Thanks John, and also Richard, Brent and Liz. I know my questions are very naive, but the following occurs to me (and I'm sure this has been debated to death by physicists): why is it assumed that this phenomena is caused by some type of matter? As far as I understand, QM hasn't been reconciled with GR gravity. Isn't this + dark matter a sign that there's something fundamental we don't understand yet? Or maybe this is the sense in which "dark matter" is already used, and I'm worrying too much about the word "matter"...
