**Abstract:**
In the Standard Model of Particle Physics there are 32
fundamental constants. In the experiments these constants can be
measured, but theoretically they are not understood.
I will discuss these constants, which are mostly mass parameters.
Astrophysical measurements indicate that the finestructure constant
depends on time. Grand unification implies a time variation of the QCD
scale. Thus the masses of the
atomic nuclei and the magnetic moments of the nuclei will depend on
time.
I proposed an experiment, which is currently done by Prof. Haensch in
Munich and his group. The first results indicate a time dependence of
the
QCD scale. I will discuss the theoretical implications.
