Ghosts

Few experiences are as widely reported, across every culture and century, as the sense of a presence that isn't there. Taken seriously as data rather than dismissed, what could actually produce it?

What the Science Finds

Most cases have ordinary, documented causes. Infrasound — sound below about 20 Hz, too low to hear but still felt — can produce unease, chills, and even visual smearing as it vibrates the eyeball; the engineer Vic Tandy famously traced a "haunted" laboratory to a 19 Hz extractor fan. Sleep paralysis, in the half-waking state, reliably produces a felt presence, a weight on the chest, and vivid intruder hallucinations — the origin of "old hag" legends worldwide. Carbon-monoxide exposure, electromagnetic fields, mould, suggestion, and pareidolia (the brain finding faces and agents in noise) account for much of the rest. No experiment has ever produced repeatable evidence of a surviving spirit.

Reading the Kernel's Ledger

The framework offers a different lens for whatever residue remains. If the deep store is read-only and holds a record of what has been, a "ghost" need not be a present mind — it can be a cached read: an old record replaying into someone's user space. That predicts exactly the features that make ghosts strange — they repeat the same scene, ignore the observer, and can't truly interact, behaving like a recording rather than a person.

And because such a read is content-addressed and reconstructed locally (the Earth is never twice in the same place — see Kernel Access), it explains why hauntings cling to buildings and objects — the local matter that travels with us through space — rather than to empty points in the void.
