A Time Dependence of QCD
Abstract
From astrophysics there are indications that the finestructure constant has changed during the past 10 billion years. Within grand unification one can deduce that also the QCD scale has changed. Tests for a time variation of this scale are described. The result of the new experiment in Munich is discussed.
