On Sunday, February 26, 2012, I did one of my Q&BA live video chats on Google+. This one was a little different than usual: it was part of the online convention Dot Con Fest 2012, celebrating geek life. In honor of that, the topic was "The Science of Science Fiction". I talked about time travel, faster-than-light travel, Star Trek, Contact, Ringworld, Dyson spheres, artificial gravity, and a lot of other fun nerd topics. I got a lot more comments than usual, which was fantastic! I'll have to do more themed chats in the future, I suppose.
And if you missed it, never fret: the entire chat is now on YouTube:
