More interesting to me is Casliber's note that science stuff is okay. So if it's not fringey you're in the clear I think?  You just can't mess with exopolitics thank goodness.  What about science fiction?  Can you start with the newer Star Trek stuff and work backwards?  I tend to favor the classics.
