I think Star Trek "jumps" into another dimension (subspace) in which everything is smaller, and jumps back to normal space at corresponding destination points. That's how the books put it down as. And couldn't they scoop up gases from the gas giant and use it to power their generators, a la bussard ramscoop ? Hyperspace i think works on a similar level. Technical points aside. I hated Darkness. Way too much teen romance, lack in plot advancement. Didn't reveal much else about the characters, other than that potential mutiny bit. Didn't explain what happened to the shuttle that dropped off in the previous episode. etc.
