How long does it take an electron to form a photon? The answer would normally be: so short a time that it cannot be measured. However, the international CERN team responsible for experiment NA63 -- mainly staffed by physicists from Aarhus University -- has now succeeded in dragging out the process, thereby making it measurable.
