Factual error: Kryten tells everyone that the matter paddle transmits matter in digital form from one place to another at the speed of light - he is very clear on this point. He then locates Waxworld, which is 200,000 light years away. Okay - so when they use the matter paddle to transmit themselves to Waxworld, why doesn't it take them 200,000 years to get there?
Factual error: The justice computer states that Rimmer is guilty of 1167 counts of 2nd degree murder, each carrying a sentence of 8 years giving a total of 9328 years. This is equivalent to 1166 counts. (00:14:00)
Suggested correction: Kryten says that the paddle sends them via subspace, so they will reach it almost instantaneously (rewatch the scene, he never says they'll travel at lightspeed).
