Corrected entry: In Star Trek TNG's 4th or 5th season, they bring Scotty back for an episode under the pretence that he put himself into a continuous feedback loop in the transporter in order to survive a crash. The episode was called 'relics'. When Geordi, Worf, and Ryker beam down, the free him from the transporter. As soon as Riker says that he is from the starship Enterprise, Scotty immediately says 'the Enterprise. I'll bet old Jim Kirk himself dragged her out of mothballs to come looking for me'. But wait. In Star Trek Generations (the movie), Scotty was on the Enterprise B when (he believed) Jim was pulled out of the ship when the Nexus (which no-one understood, at the time) collided with the ship. So, as far as Scotty is aware, Jim is dead. So why the statement in Relics about Jim being around to come looking for Scotty?
Corrected entry: Wasn't the emotion chip originally inserted via Lore's mouth, not through the top of the skull? It looks a lot bigger in the movie, too.
Correction: It can be reasoned that the cranial slot seen in the movie could be Data's equivalent of a USB port (notice there was more than one). The emotion chip was damaged (as explained in 'Descent'), and it may now be larger because it is placed inside a special corrective unit to enable it to function properly. That unit then fits into the universal port.
Corrected entry: How could a phenomenon like the Nexus travel the galaxy every 39.1 years and nobody know about it for so long? Kirk and the Enterprise-B didn't know what it was, even Picard had to ask Guinan what it was. If the energy ribbon is what killed James T. Kirk that would have been standard knowledge for everyone in Starfleet.
Correction: The galaxy is an unbelievably huge place, with new things being discovered all the time. It's certainly possible the Enterprise-B was the first ship to encounter it and survive to report it.
Corrected entry: When Geordi gives the order to evacuate Engineering, he starts to say "Bridge we have a new problem." As he is saying this, the blonde female officer can be seen ducking under the door to escape the room, but when he says, "We're five minutes away from a warp core breach," the same officer is ducking under the door again a second time.
Correction: We see one blonde from behind with similar hair at first and after the other, as you say, but we can't be sure that it's the same woman.
Corrected entry: As Data pulls his emotion chip from the holder, there is a shot of Geordi, and you can see through the visor (and they're not totally white!) (00:28:50)
Correction: You can sort of see through the VISOR, but you can't see anything distinctly. It may just be a reflection of his irises and pupils (which Geordi still has, though discolored) on the surface of his eyes.
Corrected entry: At the very beginning of the movie, we see a bottle of champagne flying in space and crashing upon the hull of the Enterprise-B. Champagne is squirting around. Well, as Khan said, it's very cold in space. The champagne should be frozen and be shattered into little pieces.
Correction: Even today, they make special (read: cheap) champagne to be used when launching ships that is never intended for drinking. In the future of Star Trek, the need to have a "champagne" that will survive a few moments in space has arisen, so if the champagne is still the same not-intended-for-drinking special brand, it would be conceivable that they added some heavy-duty anti-freeze.
Correction: No atmosphere in space means no convection or conduction to carry away heat. Radiant heat loss is slow, and the specific heat of water is high, so not enough time for a bottle to freeze anyway.
Correction: When they free Scotty from the transporter loop, Geordi says something like it has suffered less than 1% degradation. Obviously, the memory of Kirk's death was in that 1%.
