  This paper presents three aspects by which the Weyl geometric generalization
of Riemannian geometry, and of Einstein gravity, sheds light on actual
questions of physics and its philosophical reflection. After introducing the
theory's principles, it explains how Weyl geometric gravity relates to
Jordan-Brans-Dicke theory. We then discuss the link between gravity and the
electroweak sector of elementary particle physics, as it looks from the Weyl
geometric perspective. Weyl's hypothesis of a preferred scale gauge, setting
Weyl scalar curvature to a constant, gets new support from the interplay of the
gravitational scalar field and the electroweak one (the Higgs field). This has
surprising consequences for cosmological models. In particular it leads to a
static (Weyl geometric) spacetime with "inbuilt" cosmological redshift. This
may be used for putting central features of the present cosmological model into
a wider perspective.
