    The time it takes for a particle to tunnel through a potential barrier, and even the interpretation of this phenomenon, have long drawn debate. By performing an attosecond angular streaking experiment in connection with ab initio calculations, researchers have concluded that tunnelling is instantaneous for atomic hydrogen.
