RLE: here Plaintext: here
A negative spaceship is a type of signal traveling through a periodic agar such as zebra stripes. The leading edge of the signal removes the agar, and the trailing edge rebuilds the agar some time later. The distance between the two edges is sometimes adjustable, as shown in lightspeed bubble. The central part of the "spaceship" may consist of dying sparks or even simple empty space.

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...

  • ... there are 'Heisenburp' reactions which can detect the passage of a glider without affecting it in any way?
  • ... Corderships can be constructed using individual switch engines placed arbitrarily far from each other, that will still support each other using intermediary gliders and stable objects?
  • ... fuses can be made that burn arbitrarily slowly, based on sending spaceships back and forth between two rows of stable objects?
  • ... there exist 'lone dot' agars consisting of isolated cells in every generation?
  • ... that some types of spaceship, but not all, support stable Heisenburp technology, where an arrangement of still lifes detects the passage of the spaceship, emits a signal, and returns to its original state?
  • ... that, while it is impossible to build a true stable Heisenburp device that detects a passing glider without even temporarily affecting it, there are several known stable pseudo-Heisenburp devices?
  • ... that the name of the Bandersnatch, a color-changing lane-shifter device discovered in 2020, is derived from a Lewis Carroll poem that also supplied names for the Snark, the boojum reflector, and the Bellman search utility?
  • ... that the first rake that produces spaceships travelling in the same direction but slower was found in 2003, using a c/2 rake to produce 2c/5 spaceships?
  • ... that it is possible for a single Life object to simulate the evolution of an arbitrary number of other Life objects at the same time (although at increasingly slower speeds)?
  • ... that the Fast Forward Force Field reaction can transport an LWSS 11 spaces in 6 generations, creating the illusion of super-light-speed travel?
