We don't seem know much about the Beta Quadrant compared to the other Quadrants. In TOS it was suggested that the Klingon and Romulan Empires were in the Beta Quadrant, but by DS9 they both seem to be in the Alpha Quadrant. Plus if both those empires were in the Beta Quadrant, how would they be so close to the Federation to the Alpha Quadrant, to the point that Federation Starships can easily travel to both the Klingon and Romulan home worlds.
So what exactly is in the Beta Quadrant?
I don't think TOS ever mention the Quadrants. Thats something that came into being with the films and TNG.
Since the Quadrants would be next to each other its possible for a starship to travel to the capital worlds with a certain amount of ease. I can travel from the capital of California to the capital of Nevada in a few hours.
