Machine planet

From Memory Alpha, the free Star Trek reference

The machine planet was a planet located in an unknown area of space, home to a species of sentient machines. When the NASA Voyager 6 probe fell into a black hole in the early 21st century, it reemerged in this planet's system, and was repaired and extensively expanded by the machine race, becoming the V'Ger artificial organism. (Star Trek: The Motion Picture)

[edit] Background

After Star Trek: The Next Generation: "Q Who" aired, Gene Roddenberry speculated – perhaps jokingly – that the machine planet was the Borg homeworld. This idea also appeared in the non-canon novel The Return. However, no Borg homeworld has ever been mentioned in Star Trek; the planet, if a Borg world, may also have been a colony of the Borg. Also, if V'Ger indeed recorded information on "whole galaxies" while on its return voyage to Earth, as Spock's voiceover indicated, the planet would theoretically be well outside the Milky Way Galaxy.
