Trivia: The set designers added in small jokes everywhere. On the cross section of the ship near the tactical station, there are small objects in the picture that do not show up on television. (There are mice in the halls, cars in the cargo bay, a duck in a hall and a hypodermic needle in sickbay). In the halls, the red strips labeling the compartments say things like "3 hundred thousand kilometers per second, it's not just a good idea, it's the law, your mileage may vary of course", "Objects in mirror are closer than they appear to be", "A stitch in time saves nine", "In space, no one can hear you scream", and "Don't step on Superman's cape."
Trivia: A constant question during the run of all the Trek series is why Klingons look so much different, from "Star Trek: The Motion Picture" on, than they did in the original series. The real reason is the movies and later TV series had a better makeup budget. However, the "Star Trek: Enterprise" episodes "Affliction" and "Divergence" provide a canon answer. Klingons acquired genetically engineered human embryos left over from Earth's Eugenic Wars and used them to augment their soldiers. It worked but created a virus that threatened to annihilate the Klingon race. Dr. Phlox and a Klingon doctor found a cure, but it resulted in all Klingons becoming far more human in appearance. Sometime between these episodes and the first Trek movie, a cure was found, returning the Klingons to their present day "ridged-head" appearance.
Descent (1) - S6-E26
Trivia: The building used in this episode and in part two (S7 Ep1) is called "House of the Book" Brandeis-Bardin Institute Hebrew Campus, in Simi, California. It was also used in the early seasons of the Mighty Morphin Power Rangers as the Rangers Headquarters.
Half a Life - S4-E22
Trivia: One of the computer readouts that Dr. Timicin studies in Engineering has the numeric code "4077". This is a reference to David Ogden Stiers' earlier role on the series M*A*S*H.
Trivia: Early on in the episode, just after Picard realises what the terrorists are up to. He fights and disables one of the terrorists, a human played by Tim Russ, using what appears to be a Vulcan nerve pinch (although in the script it is referred to as a "carotid artery block"), which he learned from Sarek in an earlier episode. It's ironic that Tim Russ would later go on to play the Vulcan Lt. Tuvok on Voyager, and use that very same move on many an occasion.
Trivia: The transporter system in the Star Trek universe uses a Heisenberg compensator. This is to counter Heisenberg's Uncertainty Principle, which pretty much eliminated the potential for transporters, given Heisenberg's assertion that it would be impossible to re-assemble all the components of an item transported.
Trivia: Closed captioning, in its infancy in the 80s, often dropped words and letters by accident. In the original broadcast of this episode, the captioning of Riva's line, "We could dine together," lost an N, resulting in a rather bizarre exchange. Riva: We could die together. Troi: I'd like that.
Trivia: When Counselor Troi is leading Mark Twain to his quarters, Twain asks if the Enterprise has ever encountered Halley's Comet. It's a well-known fact that Twain was born a couple of weeks after the comet's appearance in 1835.
Trivia: Riker's comment, "Is it just me or does it look a lot meaner this time?" when the Husnock warship appears the second time, is not hyperbole. For that scene, the production crew modified the ship model with a third phaser cannon to subtly appear more menacing.
Booby Trap - S3-E6
Trivia: The Promellian battle cruiser is actually the alien spacecraft from the 1986 horror parody 'Night of the Creeps'. Originally it had been designed with all the detailing on the bottom since it was only filmed from below. The production staff simply turned the model upside down and presto, instant Star Trek ship.
Trivia: Starting in season 4, the number "47" appears in the dialog of several episodes (from station numbers to codes to percentages). This comes from one of the executive story editor and writer, Joe Manosky (who joined TNG in season 4). Manosky was in a club during college called "The 47 Society" and the number was written in as an inside joke. It carried its way through Voyager, DS9, and films. Writer and producer, Rick Berman, once joked "47 is 42 corrected for inflation."
Trivia: The actor that plays young Batai, son of Kamin/Picard, is played by Daniel Stewart, the real life son of Patrick Stewart.
Trivia: As Picard argues for Data, the wall behind Maddox can easily be seen as the forward wall and viewer of the Enterprise Battle Bridge, re-purposed for this episode.
Answer: He brought the Borg to the Alpha Quadrant and showed them that it was full of worlds waiting to be assimilated. Guinan's homeworld was their first stop, and they assimilated everyone and took over the planet, leaving The Survivors of her race without a home. Q is ultimately responsible for that.
Captain Defenestrator
By the time Q takes the Enterprise to meet the Borg, Guinan already knew who they were and they had already destroyed her world. Therefore the above answer can not be right. I believe Guinan is much more than she appears, and her people have had encounters with the Q in the past. It is these interactions, that obviously were not pleasant, that fuels her distrust.
oldbaldyone
That's what the above answer is saying. Q brought the Borg to the Alpha Quadrant (not Earth) and the Borg destroyed Guinan's home world in the late 2200's, which is why she hates Q. Although she met Q in 2160 and they both saw each other as enemies right away.
