Eater1.png
Eater 1 (or fishhook or simply eater) was the first discovered eater. Its ability to eat various objects was discovered by Bill Gosper in 1971. It is the smallest still life that is neither radially symmetric nor symmetric through a line, and it is the thirteenth most common still life, being less common than mango but more common than long barge. It only takes four generations to recover from being hit by a glider, making it the fastest-recovering glider eater, and it is also the smallest glider eater. As such, it appears as a stabilizer at the corner of dozens of oscillators including 36P22, buckaroo, P54 shuttle, pentoad, pre-pulsar shuttle 47, and snacker.

Did you know...

  • ... that there are 71 distinct ways for two gliders to collide, but it is unknown how many distinct 3-glider collisions there are?
  • ... that to display the smallest known gun pattern for a Gemini spaceship at 1 cell = 1 pixel, on a standard-density video monitor, a screen over one mile square would be needed?
  • ... that no odd-period glider guns were known before 1995, when a period 565 p5-spark-assisted B-heptomino loop was constructed by David Buckingham?
  • ... that even though the speed limit for spaceships is c/2 in a vacuum, in a medium of stripes agar there are "spaceships" that can travel at lightspeed along the stripes, or two thirds of lightspeed perpendicular to the stripes?
  • ... that the smallest known spacefiller pattern consists of 187 cells?
  • ... that the smallest known sawtooth pattern in Conway's Life consists of only 177 cells?
  • ... that there are now over a hundred and twenty known Herschel conduits, counting stable conduits only, and a much larger number if oscillator-supported conduits are included?
  • ... that Demonoids, Caterloopillars, Orthogonoids, half-bakery knightships, loopships and camelships are the only known types of spaceships with fixed slope but adjustable speed -- not counting 0E0P metacell-based patterns?
  • ... that a pattern exists in which no cell in the unbounded Life plane ever becomes periodic?
  • ... that several different universal constructors in Conway’s Life have been shown to be capable of constructing their own circuitry?
