Waterbear.png

Waterbear is an oblique spaceship constructed by Brett Berger on December 28, 2014. It was the smallest (in terms of bounding box) known oblique spaceship, superseding parallel HBK, until the discovery of Sir Robin in March 2018. It is also the first discovered "fast" oblique spaceship in Conway's Game of Life.

The helix, fanout devices and syntheses for the helix were found by Ivan Fomichev. The base reaction consists of a crawler consisting of a Herschel running on a track of gliders. The Herschel consumes a southwest glider and emits two gliders, one southwest and the other southeast, every 79 generations. Interactions between neighboring tracks are used to create the necessary components to recreate the helix.

Did you know...

  • ... that there are spaceship stabilizations of agars?
  • ... that block is the only known finite strict still life where each living cell has exactly 3 neighbours?
  • ... that all strict still lifes up to and including 14 cells have been found by apgsearch in asymmetrical 16×16 soups?
  • ... that c/2 orthogonal and c/4 diagonal are the only speeds of spaceships seen to emerge from asymmetric soups on Catagolue?
  • ... that all currently known standard Herschel conduits produce the same Herschel great-grandfather pattern, except for Fx158?
  • ... that eater 1 is the smallest asymmetric still life?
  • ... that in Life, no spaceship can exist with a speed of (m,n)c/x where (m+n)/x > 0.5?
  • ... that even without using fixed-cost reverse caber tosser technology, an N-bit strict still life – specifically, some length of long long (...) boat or barge – can be constructed for any odd integer N using no more than 39 gliders, and for any even integer N using no more than 38 gliders, using a temporary tubstretcher?
  • ... that even without using fixed-cost reverse caber tosser technology, an N-bit period-2 oscillator can be constructed for any odd integer N using no more than 45 gliders, and for any even integer N using no more than 46 gliders, using a temporary tubstretcher?
  • ... that it is currently an open question as to if there exists a periodic pattern whose only predecessors are its own evolutionary sequence?
