Plot hole: Why doesn't Reliant know that Khan is exiled here? The Federation is so terrified and opposed to genetic engineering that it's still illegal 300 years after Khan. So why is there no warning along with the data on the Ceti Alpha system? Kirk logged what happened with Khan and his solution of marooning him. Starships use nav data to navigate star systems. Ceti Alpha 6 exploded, yet the helmsman or computer never noticed that there is one less planet than there was when Kirk was there? There is no debris from the explosion? Ceti Alpha 5 is the exact same size and was conveniently blown into the exact same orbit as Ceti Alpha 6 used to have? So there is nothing whatsoever to make the crew even suspect that it's not 6? Enterprise would have to have scanned the planets in the system to know that one was habitable for Khan. Did Ceti Alpha 6's destruction somehow magically turn Ceti Alpha 5 into its exact duplicate? If Starfleet ships have been there to map after Ceti Alpha 6 exploded, none of them bothered to check on the exiles? Pretty callous for Starfleet, don't you think? With the technology and amounts of information available to Starfleet vessels, there is NO logical reason for the Reliant to think that this planet is Ceti Alpha 6. Finally, would the Federation be willing to test a device whose exact effects will be unknown on a planet so close to another inhabited one? (00:21:00)
Suggested correction: The answer is yes: against all known laws of science, the inexplicable explosion of Ceti Alpha VI led to Ceti Alpha V conveniently taking its orbit and making it easy to mistake for its former sister planet. A mistake would've been to give an explanation that can be debunked. By leaving it to "somehow" the movie leaves it open to a million possible rationalizations. You can even make a whole other story about the crazy circumstances that led to this incredible result.
Character mistake: While Khan is "interviewing" Chekhov and Terrell, he stated, "On Earth, two hundred years ago, I was a prince, with power over millions." The official date for this movie is 2285. That would place Khan on earth around 2085 by this statement. However, it is made clear in the episode "Space Seed" that Khan and his followers escaped earth in the year 1996: nearly one hundred years earlier. Quite a way off to be a rounding error. (00:21:45)
Suggested correction: I don't believe the earth year had been established when this movie was made and it was something the franchise applied to itself retroactively later on.
Stupidity: Reliant's prefix code is 16309. This code prevents an enemy ship from ordering a friendly ship to lower its shields or something similar. Five digits with no symbols. We know that symbols and letters aren't used since Spock uses a 10 digit set of switches to input the code. This is ludicrous. In 2016, a high powered server could crack a 6 digit password in approximately 0.0224 seconds (at 100 billion guesses/second). Any starship computer would have to far more processing power then a 2016 server. The prefix code protecting a starship from cyber attack would have to be insanely complex in order to be useful.
Suggested correction: Keep in mind the era that this movie was made in. This movie was made before PCs really existed. Computers at this time were typically huge devices or box like containers. Their data storage capacity was minuscule and there certainly wasn't any form of AI logic programs built to "hack" passwords. I know this movie is about space and set in the future but there's a lot of stuff in Star Trek movies that based on our technology or development currently, we would expect something bigger, smarter, etc. We still have problems today with people using archaic password structures like 1.2.3.4. or actually using the word password for/in their password. Back in '81-'82, I'm sure that most people would not have thought about codes being hacked. This is not to mention that in many movies, which I don't know if there is a specific reason for using 16309, codes, passwords, numbers for addresses/apt#/room#/etc and other info frequently come about as tribute, honoring, or coming from something in the lives of a film's director/producer/actor/etc! So sure with today's technology, which could have been accomplished more than 10 years ago as well, using a single string of numbers as security measures for anything is foolish and can be hack by a self running password-like cracker program... But they made this "code" back in the very early 80s when computer hacking was barely unconscionable (MAYBE) so unless these #s were a tribute or to honor something, I'm pretty sure no one was even thinking of hacking back then... We all aware of today... all about the hacking threats and YET we still have people using 1.2.3.4., the word password, or other horrible predictable password choices that can easily be broken by a password cracking program... And we know that there's a huge hacking threat requiring strong security measures but don't do so while back then, there was little awareness of the threats of hacking much less the concept of hacking altogether.
OR... in this future they have limited the number of password attempts to one a day and the ship automatically goes to red alert after a failed attempt until the right code is entered. That way it would take 7,327 years or so to try all the codes with the crew on notice and plenty of time to address the threat.
Factual error: It is long-established in Star Trek canon that onboard diagnostics can detect any animate intruders on Federation vessels. Any living thing that exists upon a Federation vessel can be identified, and its location specifically noted on Federation property. How is it, then, that there are rats aboard the Regula I space station (as observed by Doctor McCoy) that haven't been eradicated?
Suggested correction: It is not established that Regula 1 has the same internal sensors that a starship has.
It is definitely established, however, that the Regula 1 space station is conducting the most highly-classified technological research and development in the entire Federation: The Genesis Project, which entailed re-engineering whole worlds to create new ecosystems where no life existed before. If anything, Regula 1 should be equipped with even more sensitive and discriminating biological sensors than any starship in the Federation, for the express purpose of preventing biological contamination of their experiments. So, Regula 1 must have necessarily possessed the most sophisticated biological sensors available. As Dr. Carol Marcus emphasized, the Genesis Project couldn't risk contamination by so much as a microbe, nevermind foot-long rats creeping around the space station.
None of the scanning shown in the film was done by the Regula 1 station. The Reliant is what scanned the planet where Khan was found. Even if Regula 1 did have highly advanced sensors there is nothing to suggest anyone has the time or need to regularly scan for pests on the station itself. The presence of a pest in the Genesis cave itself would have been an error, but not on the station. A pest on the station has no bearing on the Genesis project itself. There are too many assumptions for this to be considered a movie mistake.
The rat was not shown in the Genesis Cave, it was shown aboard the Regula space station, where the Genesis Device itself was constructed before it was beamed inside the planetoid for a test run. The point you're missing is that the space station had rats crawling around inside, but a rat infestation wouldn't be tolerated at an ultra-top-secret research and development facility for a project that was highly sensitive to biological contamination.
Regulus One was a scientific research laboratory, the rats seen roaming the passageways were lab rats that had escaped in the earlier confusion. Genesis was their current project, but I'm certain there were many other experiments going on. Bear in mind, Carol Marcus retorted that "they waited until everyone was on leave to do this." They only had a skeleton crew aboard at the time Khan boarded the station and killed those still present who were not transporting equipment to the cavern.
Suggested correction: It was most likely a lab rat that was inadvertently freed when Khan and his followers ransacked the station. The sensors probably pick it up just fine, everyone on the station is just too busy being dead to do anything about the stray rat scurrying about.
It's the 24th Century. After all the "animal cruelty" activism of the 20th and 21st Centuries, I very seriously doubt they are still experimenting on lab rats in the 24th Century. That practice would be deemed medieval, at best, and barbaric, at worst.
Suggested correction: When was this established? There are a number of episodes of the original series where the plot depends on them not being able to detect intruders. "Court Martial" for example.
"Court Martial" is probably the worst example you could use for your argument. In that episode, the vengeful Lieutenant Commander Benjamin Finney repeatedly sabotaged the Enterprise main computer (changing ship's chronological data records in order to fake his own "death" and frame Captain Kirk for a murder that never happened). Finney also sabotaged the computer and caused the Enterprise to fall out of orbit. Indeed, Spock discovered that the ship's computer was malfunctioning due to sabotage. So, Finney was more than capable of sabotaging the ship's bio-scanners, as well, to conceal himself from a whole-ship scan. In fact, they had to resort to a very sensitive audio-scan of the Enterprise, selectively eliminating the audible heartbeats of every known person aboard the ship. When all known heartbeats were eliminated, just one unknown heartbeat remained, and its owner couldn't be identified. Therefore, Finney had certainly tampered with the bio-scanner to conceal his whereabouts. It's very doubtful, however, that foot-long rats hacked the bio-scanners aboard the Regula research station to conceal their whereabouts.
Every time the Enterprise computer system reported an "intruder alert," and every time they asked the computer for the location of specific individuals and lifeforms anywhere aboard the ship. This was all well-established in the Original Series.
It's a big leap to go from that to they can detect any living being. It is explicitly established that under many circumstances they can't even detect a full grown man if they are in hiding. This is the whole basis of the plot of "Court Martial." Even as late as The Next Generation it is established that it is difficult to find someone if they're not wearing their communicator badge.
Yet they can detect single-celled organisms on a planet's surface from thousands of miles away. The technology certainly exists in the Star Trek universe, and especially for the highly-classified Genesis Experiment. In "The Wrath of Khan," Dr. Carol Marcus stipulates that the Genesis Experiment cannot be contaminated by so much as a microbe, and complete sterility is a condition for selecting a test planet. Yet they have foot-long rats scurrying around the Genesis research facility? That is a plot hole, a continuity problem and a factual error all rolled into one.
Reliant scanned the planet to search for any life forms. That scan was inaccurate and it read Khan's entire group (and presumably the Ceti eels) as non-specific, potential life matter. Reliant's crew speculates that it could just be some speck of matter and they are completely shocked to find multiple living humans there. If they were using these highly advanced sensors you claim they were using they would not have been surprised by the presence of humans at all. And even if they could, there is nothing to suggest they should also use those sensors for pest control on their space station.
Suggested correction: Obviously the first thing the rats did was chew through the cables to the lifeform scanners.
Which would set off alarms like crazy aboard the station because preventing biological contamination of the Genesis Experiment was a No.1 priority for Dr. Carol Marcus. Undoubtedly, the station was bristling with redundant bio-scanners.
All of which had been also chewed through! No, you make a good point.
Suggested correction: Someone on the Reliant had a pet rat and one of Khan's henchmen brought it aboard Regula I to torment the lab techs. (Yes, this sounds silly, but the point is that strange and unlikely things actually happen quite often and it's exactly what makes stories interesting. As long as an event can be rationalized, unlikelihood alone isn't enough to qualify as a mistake. If it really bothers you, you might get more mileage putting it under "stupidity" since it's obviously just a lazy horror cliche).
