This episode establishes black holes as a common phenomenon in the Star Trek universe. A conversation between Archer and T'Pol purports that the Vulcans have surveyed "more than 2,000" black holes. However, by the time of Star Trek: The Motion Picture (1979), Decker remarks that Voyager VI, "disappeared into what they used to call a black hole," implying that the definition of what constitutes a black hole may have changed over the centuries. In fact, by the time of Hunters (1998), the Hirogen used a small quantum singularity to power their relay stations, which was referred to by the crew of USS Voyager as a black hole.
When designing the program that was later-named "Tactical Alert," one of the names Lt. Reed considers is "Reed Alert," an obvious reference to the "Red Alert" used in all other Star Trek series.
First appearance of the galley.
