BH must be away for the BH (!) weekend. Headline in the ARS Technica explains:

I gave up when that Maggie woman took over, with her gabbling. I quite liked Chris and Pete. But hey, a box got ticked, and that's all that matters.
(FWIW, I don't like Brian Cox much either.)

I don't like either Brian Cox, although I'm beginning to appreciate the actor a bit.
I couldn't make sense of the programme. Whatever points the contributors were making went over my head. I wonder who the target audience was for this episode. Other PhDs in Astrophysics?
