A research team from Osaka University, Nihon University and Chuo University has proposed a novel theoretical framework whose experiment could be performed in a laboratory to better understand the physics of black holes. This project can shed light on the fundamental laws that govern the cosmos on both unimaginably small and vastly large scales.Recently, the world was transfixed when the first ever images of a black hole were released by the Event Horizon Telescope. Or, to be more precise, the pictures showed the bright circle, called an Einstein ring, made by the light that just barely escaped the grasp of the black hole’s immense gravity. This ring of light was due to fact that, according the theory of general relativity, the fabric of spacetime itself becomes so contorted by the mass of the black hole that it acts like a huge lens.Unfortunately, our understanding of black holes remains incomplete, because the theory of general relativity—which is used to describe the laws of nature at the scale of stars and galaxies—is not currently compatible with quantum mechanics, our best theory of how the Universe operates on very small scales. Since black holes, by definition, have a huge mass compressed into a ...
