Death of a Black Hole: Not Disappearance, but a Tear in the Fabric of the Universe ✦
Scientists have found out: during the birth and evaporation of black holes, a sudden tear in spacetime — a ‘thunderbolt’ — can appear far from the hole, where everything is calm. Like a tiny crack that causes a dam to burst far downstream, this challenges our usual ideas about the fate of information in black holes.
A black hole is like a fabric stretched to its limit, holding everything around it. Stephen Hawking showed that it still loses mass: particles slip away like threads from a worn-out cloth. It seemed the finale would be quiet—just a disappearance.
But a computer simulation revealed a catastrophe. When the hole runs out, the fabric of spacetime doesn't smooth out but rips apart. An instantaneous rupture—a 'thunderbolt'—travels at the speed of light, tearing even calm regions. This is not a silent fading but a cosmic rending.
Hence, our theories break down at the very edge. The debate over the fate of information that falls in remains unresolved—perhaps a future theory will bring the answer. The irony is that Hawking introduced the term 'thunderbolt' in 1993 as a hypothetical quirk, and today modeling confirms its inevitability. Incidentally, Bekenstein already guessed that a black hole has entropy (a measure of disorder), and Unruh developed similar ideas.
🎯 Hawking coined the term 'thunderbolt' in 1993 as a hypothetical curiosity, not believing it was real; modeling proved otherwise.
