Research at FAIR

„The universe in the laboratory“. FAIR provides new insights into the structure of matter and the evolution of the universe from the Big Bang until today. Here, it is possible to create states of matter in the laboratory that otherwise only exist in the universe e.g. in stellar explosions or in the core of planets.
