Eater5 small.gif
An eater is any still life that has the ability to interact with certain patterns without suffering any permanent damage. The term may also sometimes specifically refer to eater 1, a very common and well-known eater. The block was the first known eater, being found to be capable of eating beehives from a queen bee, allowing the construction of the queen bee shuttle. The animation to the right shows an eater 5 feasting on an incoming stream of gliders. Eaters are extremely important, as they help stabilize and control debris created by complex reactions, allowing for the manipulation of the useful parts of those reactions. Stable reflectors in particular heavily rely on a variety of eaters to work.

Pattern collection

The LifeWiki contains one of the most comprehensive catalogues of patterns available on the internet. Within it you will find:

Did you know...

  • ... that since 2014, more new spaceship syntheses have been completed than were found in all the years between 1970 and 2013?
  • ... that as of 15 August 2017 there are 223 different still lifes known to be constructible by colliding four gliders, but it is likely that this list is not complete?
  • ... that in 2014 a new natural infinite growth pattern was discovered, starting from a symmetric random starting configuration?
  • ... that the first self-constructing Conway's Life pattern was built in 2010?
  • ... that the first glider synthesis for a c/3 spaceship was completed in 2014?
  • ... that the first "macro-spaceship" gun (a Gemini spaceship gun) was constructed in 2010, followed by the HBK gun in January 2015 and a Demonoid gun in December 2015?
  • ... that the waterbear was the first known high-speed oblique spaceship, many orders of magnitude faster than Gemini spaceships and half-baked knightships?
  • ... that there are no known direct reflectors for lightspeed wire signals, or for signals in 2c/3 wires, but that very large reflectors for these signals can be constructed using stable or periodic circuitry?
  • ... that 24 ten-cell patterns exhibit infinite growth, with 17 unique pattern types, but that it has been proven that no nine-cell pattern exhibits infinite growth?
  • ... that all still lifes up to 18 bits have a known glider synthesis, but it is still not known whether all still lifes are synthesizable?
