Did the original series have a strong scientific and technical basis?
Gene was not as science oriented as he was people oriented. He wanted to have a story that touched on all of the various conditions that human beings would face and how they would face them, and that there was a place for heroes.
He wasn't able to do that in Hollywood very easily at that time, and discovered that he was able to do it if he put it three hundred years into the future, which meant science fiction. He realised that if he's going to go into science fiction and if he's going to go into the future and if he's going to travel the stars he's going to need some scientific credibility and authenticity.
