Revision as of 16:13, 2 August 2021

A SMOS (Spaceship Made Of Spaceships) is a spaceship in a cellular automaton, consisting of multiple other spaceships colliding with each other, causing a reaction to place on where all of the spaceships are regenerated separately, but with a displacement value. Such spaceship conglomerations can be, on rare occasions, SMOS'ed again together to create a SMOSMOS (Spaceship Made of Spaceships Made of Spaceships). The ship used in the SMOS must also work as a normal spaceship by itself.

A stricter definition of SMOS requires the ships used in the SMOS to be allowed to go through 1 full oscillation cycle before interacting with the other.

Elementary Example in OCA

The T-tetromino is a spaceship in a large range of isotropic non-totalistic rules (for example tlife), as shown in Panel 1 below. It can be used to create many kinds of SMOS, one of which is shown in Panel 2. This particular SMOS, one of the simplest known, can also collide with another copy of itself in the specific rule B34enw5q6ae7c/S2ac3-cknq4-aenqt5akqy8 to generate a SMOSMOS (Panel 3).

Engineered example in Game of Life

On August 2, 2021, Goldtiger997 constructed a (16461006,16460963)c/75568091 "self-synthesising" spaceship based on a design from Dave Greene,[1] providing the first explicit SMOS in regular Life. In some phases, this oblique loopship consists of a two-glider collision synthesizing a block and a salvo of 144,219 gliders.
