If you ever want to read up on everything that's so strange about the Star Trek universe and what explanations Trekkies come up with for it, here's the right URL for some areas. I came across it today while watching an Enterprise episode because I was looking up the relationship between Romulans and Vulcans (in today's Enterprise episode, humans meet Romulans for the first time on the timeline).
Ok, I know it's nothing that would really interest the world.
