Researchers of the University of Bonn have shown that
Caesium atoms do not follow well-defined paths
Can a penalty kick simultaneously score a goal and miss? For
very small objects, at least, this is possible: according to the predictions of
quantum mechanics, microscopic objects can take different paths at the same
time. The world of macroscopic objects follows other rules: the football always
moves in a definite direction. But is this always correct? Physicists of the
University of Bonn have constructed an experiment designed to possibly falsify
this thesis. Their first experiment shows that Caesium atoms can indeed take
two paths at the same time.
