For the World is Hollow and I Have Touched the Sky (episode)

The Enterprise discovers a generational asteroid ship on a collision course with an inhabited planet.
== Summary ==
=== Teaser ===
At red alert, the detects an approaching spread of primitive, chemical fueled, sublight nuclear missiles, which are quickly destroyed by its phasers. The crew traces the origin of the missile's path. Captain Kirk orders Ensign Chekov to plot a course, for the Enterprise to proceed, at warp factor 3 to the launchers. Meanwhile, during Dr. McCoy's routine health check, a rare terminal illness, xenopolycythemia, is discovered. They do not know its cure. It will kill him within a year. McCoy insists that he can remain in his post on the Enterprise, but Kirk immediately informs Starfleet and requests a replacement.
=== Act One ===
The Enterprise arrives at the location of the missile launch, where they see an asteroid, two hundred miles in diameter. Oddly, it is not in any orbit but follows an independent course through the local star system. Its course, 241-mark-17, leads it in 396 days, to the planet Daran V, where it will collide and kill its population of 3.724 billion. Before destroying the asteroid, to prevent the collision, they scan it and learn it is an atomic-powered spaceship. They do not detect living beings. Spock guesses that the passengers are dead. The Enterprise charts a course parallel to it.
Kirk and Spock enter the transporter room, and prepare to beam onto the asteroid/spaceship. McCoy insists on joining them so the arrive inside the asteroid. They find a surface that appears geologically active, with a reddish sky, and are puzzled that the builders apparently wanted the inside of the ship to look just like the surface of a planet. The surface has large orange cylinders, from which primitive, sword-bearing men emerge. Their leader is a beautiful woman. After a brief melee, Kirk, McCoy and Spock get captured. McCoy shares a meaningful look with the leader, before he is knocked unconscious.
The beautiful woman introduces herself as Natira, the high priestess and leader of her people. Natira "welcomes" the officers to their world Yonada. The three are taken below the surface, where they encounter a large population of young and apparently healthy people. Natira leads the three into an Oracle Room, where she consults an unseen authoritative entity manifested by a decorative altar and a booming voice. Kirk and McCoy estimate that after ten thousand years in this multi-generational ship, the people no longer realize they are inside a spaceship. The Oracle "punishes" Kirk, Spock, and McCoy by shocking them with an energy beam, rendering them unconscious.
=== Act Two ===
The three regain consciousness, although McCoy remains out longer due to his illness, in some sort of guest area. Kirk then informs Spock about McCoy's condition. An old man enters the room and gives them an herb derivative to counteract the effects of the Oracle's attack, noting that many people on the ship have been punished in this way. When they tell him they are not from Yonada, he recalls how he once climbed the mountains, "even though it is forbidden," and found that the world of Yonada is not a planet at all. "For the world is hollow and I have touched the sky…", he says, before collapsing and dying – apparently from a red, glowing subcutaneous control device in his temple. Natira comes in, has the old man's body gently taken away, and seems to take a special interest in McCoy. Kirk recommends that McCoy use this to their advantage so that they may learn more about the civilization. The captain is faced with a triple dilemma: either risk violating the Prime Directive by informing the people of Yonada of their situation, destroy the asteroid with them in it, or allow it to destroy Daran V. Natira admits she is in love with McCoy and wants him to stay on Yonada as her mate. She speaks of a final destination that is rich and green and notes that the Oracle has promised they shall reach it "soon." When McCoy tells her he has only a year to live, she tells him even a day, a month, or a year with him will make her happy.
Spock and Kirk make their way to the Oracle Room, and Spock recognizes the writing as that of the Fabrini, a civilization wiped out ten thousand years prior, when their star went nova. He also sees a symbolic map of the Fabrina solar system. Prior to dying out, the Fabrini had lived underground to protect themselves. They had also built this spaceship Yonada and programmed the Oracle of the People, which is actually a powerful computer, to take their surviving civilization to another habitable planet. The people of Yonada are their descendants. Spock manages to open the door, and the two conceal themselves in the temple behind a monolith as Natira enters. She asks the Oracle for permission to marry McCoy. The Oracle grants it, so long as McCoy agrees to join the Fabrini and submit to the instrument of obedience to become one of their people. As she's leaving, however, the Oracle discovers Kirk and Spock and zaps them. They are arrested and sentenced to death.
=== Act Three ===
McCoy agrees to stay on Yonada, but begs that Kirk and Spock be released. McCoy tells her he could never be happy on Yonada knowing that his two friends had died for his happiness. Natira agrees. As Kirk and Spock prepare to return, McCoy insists on staying. Kirk and McCoy briefly argue about his decision, but Kirk agrees to leave him behind; he and Spock then return to the Enterprise. In a ritual with the Oracle, McCoy has the instrument of obedience implanted in his head and he and Natira are married. At the Oracle's command, she reveals to him an ancient book that is to be opened and read when the ship reaches the "New World of the Promise." Meanwhile, Kirk consults with Admiral Westervliet on a video screen in his quarters, who relieves him of all responsibility for the Yonada, saying that Starfleet Command will handle the situation. McCoy calls the ship with his communicator and tries to explain that by consulting the book Spock can change the Yonadas course. His instrument of obedience immediately sends him a shock of pain, and he passes out as Natira enters. MoCoy's instrument of obedience glows red, like that of the old man…
=== Act Four ===
Kirk and Spock beam back to the Yonada and Spock removes McCoy's instrument of obedience, shocking Natira. She tries to call for the guards, but Kirk subdues her and persuades her to give them a chance. He explains the history of the Fabrini and Yonada. She is very skeptical of the story and the Oracle begins to torment her through her instrument. She flees, but does not turn Kirk and Spock over to the guards. Kirk and Spock have found that a faulty part of the Oracle computer has caused a change in course. Natira consults the Oracle, which knocks her out. When Kirk, Spock, and McCoy arrive, she says she believes them and McCoy removes her instrument. Kirk and Spock move to take the book out of the temple, but the Oracle fights them, kicking up a storm and increasing the temperature in the room to 120 degrees, planning to burn them to death or until they die of heat stroke. McCoy shows them how to open the pylon containing the book and Spock uses the book to disable the heating element, as well as the Oracle, and reprogram the spaceship's course.
McCoy and Natira share a tearful farewell: She must stay to lead her people to the promised land and McCoy is determined to keep traveling the universe in search of a cure for his disease as well as for others afflicted. After correcting the Yonadas course, Spock shows Kirk the cylinders containing the vast database of the Fabrini, which contains medical knowledge, including the cure for xenopolycythemia. McCoy undergoes the very painful treatment for his illness, with Nurse Chapel at his side in the Enterprises sickbay. When McCoy emerges cured, Kirk promises him the Enterprise will soon return to the area in 390 days when the Yonada eventually reaches its correct destination. McCoy is pleased by Kirk's promise and the Enterprise leaves Yonada.

== Background information ==
* The idea of a multi-generational spaceship or "interstellar ark" is an old one that was first proposed in an unpublished paper by in 1918. Goddard's fellow rocket pioneers and also considered the idea in the 1920s. and wrote stories about the idea in the 1940s, and Robert Heinlein originated the notion that inhabitants might forget they were on a ship in his book Orphans of the Sky, a concept later reused by Harlan Ellison in his story Phoenix Without Ashes, which was adapted into the 1973 television series The Starlost starring Keir Dullea and guest-starred Walter Koenig in a recurring role.
* The prop used as Book of the People is the same one used as Chicago Mobs of the Twenties in .
* The metal helical staircase is recycled from .
* The scenes of Yonada are reused footage of the asteroid from , and the helical staircase in the control room at the end of this episode seems to be the same one used inside the Obelisk in that same episode.
* This is the only series episode to feature three actors who appeared in the original pilot : Leonard Nimoy (Spock), Majel Barrett (Christine Chapel) and Jon Lormer (old man) (not including and , which features much footage from ). Barrett and Lormer played Number One and Theodore Haskins, respectively, in the pilot.
* Whether by chance or design, the music that accompanies the appearance of the old man played by Jon Lormer is the same music by Alexander Courage that played during some of his lines as Dr. Theodore Haskins in .
* To give more depth to the planet set, the entrances to the underground civilization were built in two sizes: those in the distance were constructed much smaller, therefore creating an illusion of distance.
* The bridge scene that runs under Kirk's voice-over at the start of Act One – where Kirk enters the bridge from the turboshaft – is the same footage from the very beginning of the episode.
* The field reader tube, normally used to take a medical patient's vital signs, is used in this episode by Spock to extract McCoy's instrument of obedience and by McCoy to extract Natira's. These mark the only apparent close-up uses of this prop in the series.
* In the trailer, the scene where the Oracle turns on the heat plays without the red overlay or the heat-wave distortion effect.
* According to a call sheet, Dick Geary appeared as a security guard in this episode, but it seems his appearance ended up as a deleted scene. 
* This episode has the longest title – 11 words long – of any episode in any Star Trek series.
* In an early story outline (), it was Scott who was ill.
=== Apocrypha ===
* According to the novel The Sorrows of Empire, McCoy's mirror universe died of xenopolycythemia in 2269, as the either never encountered or destroyed the Fabrini ship. He was succeeded as chief medical officer by the mirror universe counterpart of Dr. Joseph M'Benga, who continued to serve in that position until at least 2287.
* According to the listing of , a sequel to this episode entitled "Torment of Destiny" is unfinished.
=== Remastered Information ===
* The remastered version of this episode premiered in syndication the weekend of and featured shots of a digital version of Yonada, more closely resembling real asteroids. The battle between the Enterprise and the missiles was also revamped digitally.
