In the high energy physics laboratory called CERN, just outside Geneva in Switzerland, unstable muons (a type of fundamental particle that normally undergoes radioactive disintegration after about one millionth of a second) have been found to live longer by factor of thirty when travelling at high speed around a circular machine shaped like a large hollow doughnut.
