University of Oxford researchers have contributed to three of the main exhibits, selected by the Royal Society through a highly competitive process where only around one in four applications are chosen. Dark matter makes up 85% of our universe, but scientists do not know what it is made of since we can only observe it indirectly using gravity. Alongside colleagues at Lancaster University and Royal Holloway University of London, University of Oxford researchers will be explaining how building dark matter detectors at ultra-cold temperatures could bring us one step closer to solving one of the greatest mysteries of science. Professor Jocelyn Monroe (Department of Physics, University of Oxford), said: ‘Our research uses the most advanced quantum technologies (originally developed for quantum computing) at ultra-cold temperatures to build the most sensitive dark matter detectors to date. They will not be disappointed.’For full details of all the activities and events at the Summer Science Exhibition click here.
