I'm going to Ad Astra, the Toronto science fiction convention, this year again. And this time I'm even giving a talk: a presentation about dark matter. I intend to keep it at a conversational tone and hopefully accessible for most, and I'm spicing it up with lots of science fiction references (I always wanted to use them for something) -- but it's going to be real science.
I'm also going to be on the panel of scientists answering questions from the audience. (I also offered to be on a couple of other panels, but at the moment it's not clear to me if they are included in the final programme.)
If you are in Toronto the weekend after next, maybe I'll meet you there.
