Feeding black holes develop a fractal skin as they grow. That’s the conclusion of simulations that take advantage of a correlation between fluid dynamics and gravity.
“We showed that when you throw stuff into a black hole, the surface of the black hole responds like a fluid – and in particular, it can become turbulent,” says Allan Adams at the Massachusetts Institute of Technology. “More precisely, the horizon itself becomes a fractal.”
