backrake to produce complex long-term behavior

Bill Gosper, 26 February 2006

to have regularized: the last twelve bursts from the left formed

a geometric progression of trapezoids. But the top two corners

of the next "trapezoid" are missing, as were several previous.

To see that the trapezoid progression is exactly doubling,

click with the up/down scaling cursor on the limit point.

`...[O]bserve that the bursts forming the bottom-left corners are acute Vees (inset) flying backwards! In fact, the inset shows two backwards mirror image Vees flying apart. This is seriously weird by the following argument.`

Experiments on this scale nearly always take on a characteristic expanding star shape, with typically eight or fewer "limit" points, each receding with the velocity vector of a hypothetical glider or spaceship launched from the Origin by a Big Bang. (Any finite initial configuration (Origin) is infinitesimal compared with with these billions-wide star diagrams.) The diagrams are often crisscrossed by numerous linear features at many different angles, e.g., the patterns on Nick Gotts' weblog or the pattern shown below.Golly screen shot of 'nick-gotts-g' around generation 2,000,000

The interaction of the downward puffer's trail with the first

bounce of its backrake produces two very sparse LWSS waves.

The components of each line have equal velocity vectors, easily determined by which of the star-points radiates the extended line. The Origin is a ninth point which radiates all lines of immobile objects. (The production of particles with a nonstandard velocity would create an additional star-point.) Lines joining two star-points are guns or puffers. Thus the little tick designated by the red arrow in gottspuzz.png can only be a wave of a million or so spaceships (MWSS in fact) pointing toward the N spaceship limit, which unfortunately is graphically inapparent because no spaceships are actually escaping. (They can't be heading S because there was a single pixel NW-SE jog in that tick that my screenshot was too slow to catch.)

Thus when several rays emanate from the vertex of an internal wave crossing, it is easy to see the chain of causality, i.e. which lines are inputs and which are collision products, because components along a ray are older toward its star-point.

In other words, Vees fly frontwards.

And one of the two arms (apparently the sparser) of these backwards Vees heads at an "inexplicable" angle, i.e., not through a star-point!
