Scientists have announced the experimental discovery of a tetraneutron, a new and exotic state of matter that could also have properties that are useful in existing or emerging technologies.Theoretical physicist James Vary has been waiting for nuclear physics experiments to confirm the reality of a ‘tetraneutron’ that he and his colleagues theorized, predicted, and first announced during a presentation in the summer of 2014, followed by a research paper in the fall of 2016.’Whenever we present a theory, we always have to say we’re waiting for experimental confirmation,’ said Vary, an Iowa State University professor of physics and astronomy.
