Sagittarius A

Apparently they have discovered a black hole at the centre of our galaxy: it has been described as 'super-massive'. What that means is that it is four million times the size of the sun. And we've just discovered this thing!! I mean I've missed the obvious before, far be it from me to comment, but I don't think I've ever missed anything four million times the size of the sun (even if it felt like it).

Lecture in Trinity went very well, and was delighted to see some old friends and teachers there.

Someone on 'Morning Ireland' this morning questioned whether that was the black hole into which the €34 billion to be spent on the national transport plan would go!!!
