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 the fact that, according to 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.
Understanding - Holes - Theory - Relativity—which - Laws
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 tiny space, reconciling these wildly successful but thus far conflicting theories is necessary to understand them.
One possible approach for solving this conundrum is called string theory, which...
