Black Hole Information Loss

Black holes are often framed as cosmic cul-de-sacs, places where matter and energy vanish, and with them, the information they carry. Popular science stories speak of a “paradox”: if a black hole evaporates via Hawking radiation, does the information about everything it swallowed disappear forever? It is a compelling image: the universe swallowing secrets into a pit from which nothing can escape.

Yet this metaphor misleads. It assumes information is a thing — a substance that can be trapped or lost. It also treats spacetime as a container in which events happen, with an outside observer measuring what enters and leaves. Relationally, there is no outside vantage; the universe has no external ledger against which information is counted. Information is not a static object, but a measure of relational potential, a way in which possibilities can be actualised or constrained.

What is called “loss” is not destruction but transformation. As matter and energy interact near a black hole, relational patterns reconfigure. Hawking radiation does not erase the universe’s relational potential; it shifts it. Information is never outside the network, never lost, because it was never a discrete thing to be confined.

The story of disappearing information relies on a substance metaphor and an external frame. Stripped of these illusions, black holes are not mysterious prisons of secrets, but regions of intense relational reconfiguration.

Information is not swallowed; it is reframed — a transformation of relations, not a vanishing act.
