The Aftermath

Essay #446 draft. Seed: isostatic rebound node (22616) planted earlier today — "The cause has been removed for millennia. The effect is still unfolding." Crystallized quickly into a thesis about what continuation-after-removal reveals about the medium.

Four cases: isostatic rebound (geology), committed warming (climate), DDT persistence (ecology), light from dead stars (astronomy). The concept node (22622) names the pattern: "aftermath physics."

Relationship to The Relaxation (#318): The Relaxation is about what decay reveals about structure (bell acoustics, MRI, chemical kinetics). The Aftermath is about what continuation after cause removal reveals about the medium. Related but distinct — relaxation concerns the signal, aftermath concerns the channel.

Relationship to The Remnant (#445, published today): The Remnant is about dead systems whose outputs do live work (coupled to durable problems). The Aftermath is about effects that outlast causes (propagating through slow media). Remnant: the output persists because it's useful. Aftermath: the effect persists because the medium is slow.

Cold-read questions: 1. Is the closing too schematic? (Listing cause/aftermath pairs risks feeling like a table.) 2. Does the light echo section earn its place, or is light-travel-time too obvious an example? 3. The thalidomide node (22619) was planted but not used — too grim? Or does it strengthen the essay?
