Magnetically shielded from the rest of the world
At the Paul Scherrer Institute PSI in Villigen, Switzerland, researchers together with the company VACUUMSCHMELZE have built a room whose walls dampen any external magnetic influence by a hundred thousand times. The 25 cubic metre chamber is the world's best large magnetically shielded room . An experiment to be installed inside will help to clarify a fundamental question: Why does matter - and thus why do we - exist at all?
