I see quite a few drama's that skirt some scifi type elements (a cyborg here, an alien there, and every once and a while a full-fledged time-traveling theme), but I was wondering if there are any that are 'hard' sci-fi.  In case some don't know, the term Hard Scifi refers to sci-fi than not, shows like Star Trek would be considered 'Hard Scifi"  where there is more than just one or two science fiction type elements, 

If any help can be given, thank you, if none can be given, thank you for your time anyway
