  The so called Telelateral Conformal Gravity (TCG) is a first order gauge
theory describing inertia as internal, scale invariant geometry. The Conformal
Affine Theory (CAT) unifies other interactions into TCG in a minimalistic
scheme via an exact holographic gauge-gravity duality. In the three parts of
this Letter, the currently topical bimetric gravity models are obtained as
non-inertial gauges in the CAT, the geometrisation of electromagnetism by
Hermann Weyl is brought to a completion, and it is sketched how the rest of the
Standard Model could result from the assumption of a light cone, respectively.
The radically intuitive CAT suggests the possibility of further transgressive
unification of sciences.
