How a Quantum “Pillow” Saves a Black Hole from Infinity ⚡ экспресс
A new study examines the quantum-deformed Kazakov–Solodukhin black hole. Its main feature is the deformation parameter η, which removes the central singularity, replacing it with a region of finite curvature at radius r = η. It's like turning an infinitely sharp needle into a blunt tip. This smoothing slows down the hole's evaporation by reducing the Hawking temperature, and shifts the photon sphere, altering the shadow size. Such features can be tested through observations in strong gravitational fields, for example, near supermassive black holes.
At the center of a black hole, classical theory paints a point where density and spacetime curvature shoot to infinity — like an infinitely sharp needle. But quantum corrections, tracing back to the work of Karl Schwarzschild, add a tiny “pillow”: space cannot collapse to zero.
Because of this, the “horizon” — the boundary of no return — shifts. The famous radiation discovered by Stephen Hawking weakens, and thermal characteristics become more stable. Even the black hole’s shadow — that dark silhouette — changes size, though it keeps its round shape. The biggest surprise: if the quantum pillow were just a bit thicker, the horizon could vanish entirely, exposing a calm core to the outside world.
🎯 If quantum corrections were slightly stronger, a black hole could lose its horizon entirely, exposing its smooth core to the outside world.
🎬 In the movie Interstellar, the heroes hope to unravel the quantum mysteries inside a black hole — and the new model makes that idea a bit less fantastic.
