  When considering possible time variations of fundamental physical constants
one has to keep firm well established principles. Following this approach we
keep firm the Action Principle, General Relativity (the Equivalence Principle),
and Mach's Principle. Also we introduce a new principle under the name of
"TOTAL INTERACTION" and reconsider Weinberg's relation with a new approach.
Consistent with all these principles we find that all masses increase linearly
with cosmological time (THE MASS BOOM) and that Planck's constant decreases
also with this time.Then the whole quantum world shrinks with time too. This is
the cause of the red shift
