  We present here a panoramic view of our unified, bi-scale theory of
gravitational and strong interactions [which is mathematically analogous to the
last version of N.Rosen's bi-metric theory, and yields physical results similar
to strong gravity's]. This theory, developed during the last 25 years, is
purely geometrical in nature, adopting the methods of general relativity for
the description of hadron structure and strong interactions. In particular,
hadrons can be associated with "strong black-holes", from the external point of
view, and with micro-universes, from the internal point of view. Among the
results presented in this extended summary, let us mention the elementary
derivation: (i) of confinement and (ii) asymptotic freedom for the hadron
constituents; (iii) of the Yukawa behaviour for the strong potential at the
static limit; (iv) of the strong coupling "constant", and (v) of mesonic mass
spectra. Incidentally, within the present approach, results obtained for
hadrons can yield information about the corresponding multi-verses, and
viceversa.
