Vacuum’s Memory: How Information Survives in a Black Hole ✎ express
The black hole paradox has haunted physicists for decades. If a hole evaporates, where does its contents go? Discoveries by Stephen Hawking and Jacob Bekenstein showed that saving the laws of nature requires an unconventional move.
That knot is a fuzzball, a shaggy quantum tangle. On its surface, like the back of an embroidery, all information about what fell in gets imprinted: from atoms to starlight. This resolves the clash with entropy (a measure of disorder), and the vacuum dutifully follows quantum rules. Astoundingly, the threads seem to sense the looming catastrophe in advance and weave themselves into a protective pattern just in time.
The recording density on a fuzzball is staggering: a knot the size of a football could store information about every human who ever lived, down to their last thought.
The idea of writing data onto a black hole’s surface echoes holographic storage from science fiction — for instance, in the ‘Star Trek’ series.
