A special note from Artifactsofmars
After my humble beginning video called "Space Happy", I began looking at the fact that Star Trek fan films, and indeed Star Trek the original series rarely, if ever, discussed any scientific facts. Instead they simply make things up, often preferring to deal with social and political issues which have no place in a science fiction film. 
       Today I work to include both real exoplanets and deal with scientific facts in my fan films. I also create my own alien vegetation and sometimes alien nasties too. Nowhere else will you find someone referencing things such as the mystery fires in Canneto, Italy ("Fire Crisis") or the Bermuda Triangle ("Bermuda's Triangle").  Nowhere else will you find someone using real exoplanets in their plots, or discussing their suns and gravity. That is a feature that I added along the way. 
     Yes some Star Trek fan films feature people standing around talking about political and social issues, rather than exploring the galaxy.  If that is what you expect to see, you won't find it here.
