Breakthrough in quantum gravity moves scientists towards cosmic mysteries

Southampton UK (SPX) Mar 11, 2024
Scientists are a step closer to unravelling the mysterious forces of the universe after working out how to measure gravity on a microscopic level. Experts have never fully understood how the force which was discovered by Isaac Newton works in the tiny quantum world. Even Einstein was baffled by quantum gravity and, in his theory of general relativity, said there is no realistic experiment which could show a quantum version of gravity. But now physicists at the University of Southampton ... read more
