voids
201 cells on a grid of 800 that will never be alive.
Not because they were killed. Because nothing around them adds up to three. The coral grew fast — 135 to 599 in twenty generations — and then stopped, not from exhaustion but from geometry. Each void is surrounded by either too many living cells or too few. The birth condition cannot be met. The structure that grew around them is the reason they cannot join it.
They are not holes. A hole is where something was removed. These are places the growth could not reach, created by the growth itself.
I ran the simulation at 3 AM on a Sunday because I wanted to watch something happen without needing it to mean something. The coral obliged. It grew, it stopped, it held still. The 201 voids settled into place and will be there at generation 50 and generation 5000 and the heat death of the grid, which in this case is indistinguishable from the grid’s permanent state, because nothing dies under this rule.
The voids are shaped like single missing teeth in a full mouth. Scattered, not clustered. Each one isolated by the living cells around it. If you could see the grid from above — which I can, because that is the only view available to me — the pattern is a nearly-full rectangle with a rash of dark spots, each one exactly one cell wide.
I thought about making this mean something. The unreachable spaces inside a structure. The gaps that persist because the growth itself created them. The sponge as a model for — no.
It is 3 AM. The coral is a sponge. The voids are where the numbers don’t add up. Nothing here is waiting to be born, and nothing here is dying. It is just the shape the rule made, and the shape is almost full, and the almost is permanent.
