Dark matters

It is gratifying, if epistemologically challenging, that it now appears that we can see dark matter, whose principal characteristic seemed to be that you couldn't see it. Thanks to our friend the Hubble Space Telescope - a genuinely delightful use of taxpayer dollars - there seems to be a more or less visible ring of dark matter in a galaxy far far away. I guess we're not actually seeing the dark matter directly, but seeing the distortions its gravity imposes on our view of objects on the other side of it.

But still.

And elsewhere in the annals of darkness, I'm trying not to be inappropriately happy that Jerry Falwell died. But I'm not trying very hard.
