But now an Icelandic physicist, Steinn Sigurdsson, says he knows how to detect them. His idea is to take advantage of the strange state of matter known as a Bose-Einstein condensate, in which clumps of a million ultra-cold atoms behave as a single entity.
Extra space dimensions are a prediction of leading theories that attempt to unify all the known forces…
