Titan, Dead or Alive? A Debate

I thought you'd enjoy a video from a recent event at the Denver Museum of Nature and Science, in which David Grinspoon invited "planetary polymaths" Ralph Lorenz and Jeffrey Moore to have a debate about the nature of Titan: is it an internally geologically active world, like Earth, or is it internally dead with a surface shaped by its weather?  Grinspoon sets the stage and then Ralph and Jeff make their cases in lengthy presentations that do not skimp on the science, followed by discussion and Q and A. Enjoy!
