The Gosper glider gun is the first known gun, and indeed the first known finite pattern with unbounded growth, found by Bill Gosper in November 1970. It consists of two queen bee shuttles stabilized by two blocks. Its 36 cells remain the smallest size of any known gun, although the Simkin glider gun discovered in 2015 shares this record.
As the Gosper glider gun can be constructed with only 8 gliders, it has the smallest known glider synthesis of any gun. It can be destroyed completely by 2 gliders, as shown below.
Trivia
- There are two other ways in which queen bees can interact to form gliders,[1] and a third queen bee can be used to reflect a glider and make a "pseudo-Gosper gun".[2]
