Psi 2000

Psi 2000 was an ancient planet that disintegrated in 2266.

Before the planet's end, a science team had been stationed there on behalf of the Federation. The gravitational shifts associated with the disintegration of the planet resulted in the creation of large strings of water molecules known as polywater which resulted in the Psi 2000 intoxication.

Shortly thereafter, a landing party from the USS Enterprise beamed down to the planet and discovered the science team dead. During their investigation, Lieutenant junior grade Joe Tormolen unwittingly contracted the Psi 2000 intoxication and brought it back aboard the starship.

Suffering from the effects of the Psi 2000 intoxication, Lieutenant Kevin Riley powered down the ship's warp engines, causing the ship to begin spiraling towards Psi 2000. Chief Engineer Montgomery Scott was able to push the ship out of harm's way by initiating a cold start of the engines. (TOS: "The Naked Time")

Scotty later recounted these events to USS Enterprise-D chief engineer Geordi La Forge in 2369. (TNG: "Relics")
