Life is full of continuity errors, so why should movies and TV shows be any different? Especially when we’re talking about Star Trek, a series that has produced roughly 700 episodes and 10 movies to date not counting the new movie that has thrown most of existing continuity out the window.

Voyager was a ship alone in the Delta Quadrant. The Ship did not have access to star bases to replenish lost supplies and replicator rationing was in place throughout the show do to limited energy resources.

How many shuttles did Voyager have at the beginning and how many were built afterwards? The aft section of an Intrepid-class vessel does not seem to be large enough to hold more than eight Starfleet shuttlecraft, and Neelix’s ship which seems to be somewhat larger has to be stored as well. Fitting the Delta Flyer into the shuttlebay is still another problem.

The chart below shows at least 16 shuttles were destroyed during the 7 years Voyager was in the delta quadrant. If Voyager did not originally have that many how were more built with an energy shortage?

Photon Torpedoes

In the second Voyager episode the cloud Tuvok states there are 38 photon torpedoes and they can’t be replaced once used. Nevertheless, the number of torpedoes used in the following 7 years exceeds 38 by far, even if we take into account only those which were seen or explicitly mentioned as being fired. The resulting lower limit is 93 torpedoes.

Ears come off?

In Unification, Part I Dr. Crusher asked Data if his ears come off. Data replies that they are fully integrated and do not. However, in ‘Data Lore’ Lore who is identical to Data is shown without ears after being disassembled.

Does Data Float?

In Descent, Part II Goerdi tells a story about how Data fell into a lake and had to walk all the way back to shore because he could not float. However, in Insurrection Data suddenly had can float.


What did Data do to Spot to cause him/her to change breeds and genders?

In “Data’s Day” and “In Theory” Spot was a male, long-haired Somali cat.

In “Force of Nature” and “Genesis” Spot was a female American short-hair orange tabby cat. In “Genesis”, she even gave birth.

In “Generations” Spot is still a American short-hair orange tabby cat no gender is mentioned.

The Star Trek Encyclopedia jokingly suggests that Spot may be a shapeshifter or the victim of a transporter malfunction.

Can holodeck objects exist outside the holodeck?

Sometimes holodeck matter disappears instantly.

Sometimes holodeck matter disappears slowly.

In Elementary Dear Data, Professor Moriarty hands Data a holographic piece of paper.

Data carries the same paper all around the ship. It never disappears

Water from the holodeck seems to be able to exist outside the holodeck.

Frozen water too

Can you Turn while in warp?

In the multiple Voyager episodes including “Fury” it is said you can not turn while in warp.

Janeway: “Tom, what’s the first thing they teach you about maneuvering at warp?”
Tom: “‘Faster than light, no left or right.’ When possible, maintain a linear trajectory. Course corrections could fracture the hull.”
Janeway: “Exactly. We’d have to drop to impulse every time we made a course change.”

Yet this has been done many times.

In “The Wounded”[TNG], the Enterprise-D is flying in close formation with the Nebula Class starship Phoenix, escorting that ship back to Starfleet for having been naughty. The captain of the Phoenix changes course.It engages in a slow banking turn to starboard, at warp, the ‘warp stars’ streaking by.

In another episode the drive section of the Enterprise is seen making an almost 360 degree turn while in warp.

Money does not exist in the 24th century.

This is shown in the examples below:

Kirk tells Spock about 20th century Earth: “They’re still using money. We need to get some.” In the same movie, when Kirk is unable to pay in the restaurant, Gillian asks sarcastically, “Don’t tell me they don’t use money in the 23rd century.”, and Kirk tells her “Well, we don’t.” (“Star Trek IV”)

Picard tries to explain to Ralph Offenhouse from the 20th century that there would be no need for his law firm any longer: “A lot has changed in three hundred years. People are no longer obsessed with the accumulation of ‘things’. We have eliminated hunger, want, the need for possessions.” (TNG: “The Neutral Zone”)

When she asks how much the ship has cost, Picard tells Lily: “The economics of the future is somewhat different. You see, money doesn’t exist in the 24th century… The acquisition of wealth is no longer the driving force in our lives. We work to better ourselves and the rest of humanity.” (“Star Trek: First Contact”)

When Nog suggests that Jake should bid for a baseball card in an auction, Jake says: “I’m human, I don’t have any money.” Nog replies: “It’s not my fault that your species decided to abandon currency-based economics in favor of some philosophy of self-enhancement.” Jake: “Hey, watch it. There’s nothing wrong with our philosophy. We work to better ourselves and the rest of humanity.” (DS9: “In the Cards”)

Paris says about the significance of Fort Knox: “Well, uh, when the New World Economy took shape in the late 22nd century and money went the way of the dinosaur, Fort Knox was turned into a museum.” (VOY: “Dark Frontier”)

Or Does it?

Kirk says, “The Federation has invested a great deal of money in our training.” (TOS: “Errand of Mercy”).

Cyrano Jones negotiates the price of the Tribbles with the bartender on a Federation space station. The bartender is expected to pay with credits (TOS: “The Trouble with Tribbles”).

McCoy negotiates with an alien about a transfer to Genesis, and he says he would have enough money for that (“Star Trek III”).

Scotty says that he is going to buy a boat (“Star Trek VI”).

Beverly Crusher buys a roll of cloth, and has her account on the Enterprise billed (TNG: “Encounter at Farpoint”).

The Federation bids a sum of 1,500,000 Federation credits for the Barzan Wormhole (TNG: “The Price”, offer depicted in STTNG: The Continuing Mission).

Federation officers have to and are able to pay for drinks and for holosuite usage in Quark’s bar (DS9).

What is the value of Gold?

The Ferengi valued gold as a precious commodity then suddenly it was consisted of be little more than a medium for suspending latinum in.

When bidding for the Barzan wormhole, the Ferengi offered to match anyone’s best offer and to add a bag full of gold.. (TNG: “The Price”)

When the fictional character of Rumpelstiltskin arrived on Deep Space 9, he thought he was called upon to spin straw into gold. (DS9: “If Wishes Were Horses”)

Dialogue in TNG: “The Last Outpost” and “The Perfect Mate” suggests that at least as late as 2368, Ferengi considered gold valuable.

In “Little Green Men”, Quark says to a 20th-century Human that “gold is good”.

However, by the time of “Who Mourns for Morn?”, Quark describes gold as “worthless”.

One explanation for this apparent devaluation of gold is the fact that the Ferengi had only recently made First Contact with the Federation and. Replicator technology


In TOS Klingons had flat foreheads while Klingons for later series and movies had ridges on their foreheads. Was this the result of genetic engineering, cosmetic surgery or a virus as explained in Enterprise?

Gene Roddenberry himself reportedly believed any “explanation” was unnecessary as the makeup seen in the films and the later series would have been too expensive during the 1960s. Roddenberry felt it was best to simply imagine that Klingons always had ridges.

However, this preference was tossed out the window when the change was noted by the DS9 crew in “Trials and Tribble-ations”.

In the two Enterprise episodes “Affliction” and “Divergence” we learn what has to be considered the ultimate truth about the appearance of the TOS Klingons. In 2154 the Klingon scientist Antaak, supervised by General K’Vagh, devises a program to use the genetic improvements of human Augments to create a new breed of Klingon warriors. Several Klingons, including K’Vagh’s son, volunteer to have themselves genetically altered. One of the side effects is that they lose their forehead ridges. But soon a new problem emerges. The Levodian flu, a usually rather harmless infection, mutates because of the human DNA and becomes airborne. The illness now threatens the lives of millions of Klingons. Based on the virus Dr. Phlox, who has been abducted by the Klingons, develops an antivirus. The antivirus takes away the genetic superiority from the Klingon Augments. Any other Klingon who is given the antivirus as a cure against the mutated virus loses his forehead ridges just like the Augments. Dr. Phlox says that the children of the so treated Klingons would inherit their look. Even if the trait were recessive, it would perfectly explain the existence of smooth-headed Klingon still more than a century later.

I personally accept Roddenberry’s suggestion that TOS-era Klingons always had ridges. In keeping with this theory I would conclude that the DS9 reference was merely a joke by the episode writers and then perhaps the Augment virus had no lasting effect on the Empire. The disease may have been cured relatively quickly following the events seen in the Enterprise two-parter. After all, there was no reference to it in the “later” series.

DS9 Trills are completely different than TNG Trills in almost all respects.

In TNG Odan and the female host shown at the end of the episode have a quite different outer appearance than all Trills shown in DS9, including Jadzia and Ezri Dax and dozens more. Neither was any TNG Trill with forehead bones shown in DS9, nor was there any mention that there are two types of Trill hosts in any of the two shows.

TNG Trill Odan

TNG Trill Odan female host

DS9 Trill Jadzia Dax

DS9 Trill Ezri Dax

The symbiont in the TNG episode looks remotely similar to the one in DS9.

TNG symbiont

DS9 symbiont

What is the nature of the Trill species? In TNG we learn that the symbiont totally controls the host’s body and mind. It is a key point of the episode that the prominent Ambassador Odan consists of the symbiont only, while his hosts merely serve as containers.

The DS9 Trills couldn’t be more different. Once the symbiont is implanted into the host’s body, the two individuals form a joined species and therefore a new person. This person does not only take over the memories of the symbiont, the current and all of the previous hosts, but also parts of their personalities. Thus the new humanoid host does not really lose their personality, but even feels as if it were extended by the symbiosis.

Odan of TNG cannot be beamed because it would kill him, but the impression is created that this is a general peculiarity of Trills. Dax, on the other hand, does not have any problems using the transporter, and not any other DS9 Trill either.

Odan, having been implanted into a new female host, does not mind continuing his relationship with Beverly. Whereas this is strictly prohibited for DS9 Trills (DS9: “Rejoined”).


The Romulans used to look just like their Vulcan cousins until they were given characteristic V-shaped forehead bones in TNG.

Non-Romulan Disguises

In TNG Picard, Data and Troi all are cosmetically altered to infiltrated the Romulans. They have V-shaped foreheads like the all Romulans at this time. Yet Spock is able to live on Romulus without a V-shaped forehead and without arousing suspicion.

James R. Kirk?

Vader and Mcfly in the semetary in “subrosa”. Probably intentional, and not an actual mistake.

In Inserection Dianna says to Riker “Yuck! I have never kissed you with a beard before”. When in fact she has kissed him with a beard at least on 4 separate occassions previous.

In the TNG Episode ‘Dyson Sphere’ the Enterprise beams Geordi and Scotty aboard with the shields still up. Last time I checked you couldn’t do this.

The elogium happens only once in an Ocompa female’s lifetime . An Ocampa female must conceive during this time if she is ever to have a child. If this is truly the case it would mean the Ocampa population would reduce by at least half every generation.

Resistance is Futile?

All Borg used to say “few-tile” except Seven of Nine who pronounces it as “few-tul”. Locutus said “few-tile”. Data says “few-tul” in “Star Trek: First Contact”. But Data is not and never has been a Borg . Who is correct?
