That second could be fudgeable. A method of interuniversal travel that depends on hacking about the strings that bind the universe together in space and time could be plausibly expected to have consequences more traumatic than mishaps with transporters or godling-populated wormholes. The character of Security Officer Deanna Troi alone was worth it. I wonder if Duane did write the character after seeing "Face of the Enemy". Duane certainly managed to make Troi's duplicate rather unexpectedly terrifying, and with style--the paraphrase of an Einstein quote--"Put your hand on a hot stove for a minute, and it seems like an hour. Sit with a pretty girl for an hour, and it seems like a minute. THAT'S relativity."--delivered to LaForge in the agony chamber was noteworthy.
