Awoke early this morning (5ish) evidently stressed by the prospect of speaking to the cosmology researchers at lunchtime.

Turns out it was with good reason. I managed to embarrass myself thoroughly at least a couple of times demonstrating my woeful ignorance in front of about 20 of them plus three academics. The latter, sitting up at the front and engaging in lots of discussion which was good, were positive about the session but I couldn't help feeling that in the one thing I'm supposed to be as much of an expert as I'm ever likely to be, I was woefully inadequate.

On the upside, they did at least laugh at my dismissal of them starting four minutes late as not a problem and hardly surprising in the light of the billions-of-years timeframes they're normally dealing with.
