A common topic is astronomical doomsday: ways mythical and real the world can end. He's fascinated by asteroid and comet impacts, and is a big supporter of finding, tracking, and ultimately deflecting any dangerous rocks heading our way. 

About TEDx, x = independently organized event  

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
