物理学家发现了一个解决“不可能解决”的引力之谜的方法

Now, a pair of papers recently published in Physical Review Letters has changed the calculus. The papers contend that it’s possible to access quantum gravity after all—while learning nothing about it. The papers, written by Sougato Bose at University College London and nine collaborators and by Chiara Marletto and Vlatko Vedral at the University of Oxford, propose a technically challenging, but feasible, tabletop experiment that could confirm that gravity is a quantum force like all the rest, without ever detecting a graviton. Miles Blencowe, a quantum physicist at Dartmouth University who was not involved in the work, said the experiment would detect a sure sign of otherwise invisible quantum gravity—the “grin of the Cheshire cat.”
