One thing about Dark Space (As in, the area between the galaxies) is that everything we do is always pulled on by the black-hole core of the Milky Way Galaxy (if we now accept that the core consists of Black holes and exploding stars). In Dark Space, there would be such a pull from the other galaxies too. Think of it like this: You are constantly being pulled in one direction and just follow along. Suddenly, someone grabs your legs and arms and pull them in other directions. The pull would slowly and steadily rip you apart. The ships would probably only be able to stay in Dark Space for a short amount of time before they start to break asunder.
