Enterprise is on its way to investigate a black hole in a trinary star system. Since the system is only reachable by impulse engine, the crew suddenly has time for less important matters. Captain Archer starts working on a preface of a book about his father and orders Trip to fix his chair. Hoshi takes over the mess hall as chef is sick. Malcolm starts working on a new security protocol. But T'Pol notices that the crew's behavior is becoming erratic. They seem to be fixed only on the thing they're doing right now and nothing may interfere. Hoshi wants to get a recipe right, Phlox tries to extract a piece of Mayweather's brain after he complained on a mild headache and Archer even yells at his dog while trying to write the preface. Then all the crew pass out and T'Pol must save the ship. Written by Arnoud Tiele (

Did You Know?


The episode has the theme of a Star Trek crew being affected by a phenomenon, which makes everyone on the ship lose emotional control, completely grinding efficiency to a halt. This theme has been used several times previously, whether treated tragically or comically by the script. Examples include, but are not limited to, Star Trek: The Naked Time (1966), Star Trek: The Next Generation: The Naked Now (1987), Star Trek: The Next Generation: Sarek (1990), and Star Trek: Deep Space Nine: Fascination (1994).

In the text Archer is writing about his father, there's a typo near the bottom: "his won" should be "his own" See more »


[first lines]
Sub-Commander T'Pol: Science Officer's log, August 14th, 2152 - Enterprise remains on course for the trinary system. I've transmitted a distress call, but the nearest Vulcan ship is more than nine days away. By the time they arrive, they may only find debris, if that. Even if Enterprise makes it past the black hole without being destroyed, it seems likely the crew won't survive.

Obsessive Behavior
12 January 2008 | by claudio_carvalhoSee all my reviews

While traveling to observe a black hole in a trinary star system, the captain and crew of the Enterprise are affected by the radiation and become obsessive with trivial issues: Captain Archer with the preface of the biography of his father; Trip with the Captain's chair; Reed with a new security protocol; Hoshi with the galley; Dr. Phlox with Travis' brain. T'pol is not affected and notices the erratic behavior of the crew, and when they faint, she studies a route to save the Enterprise and the crew.

"Singularity" is a simple and tense episode. There is no action, no attacks, indeed anything but the weird behavior of the crew and their preoccupation and obsession with minor situations. In the end, it entertains. My vote is seven.

Title (Brazil): "Singularidade" ("Singularity")
