- Dave Lister (White Hole)
Gravity pool, also known as Grav-Pool, was a popular bar game on Earth in the mid-22nd century.
Upon reaching adulthood, Dave Lister still frequented the Aigburth Arms, and had had become something of a legend on the Grav-Pool table.
Three million years later, Lister was able to put these skills to the test when the "played pool with planets". He did this whilst drunk, which always improved his game. Lister succeeded with a trick shot - firing a nuclear bomb from Starbug to knock a planet into a sun, causing a solar flare to knock a larger planet into (and block up) a white hole. (White Hole)
