Title: Gravi-weak unification and multiple-point principle

The problem of self-consistency of the unification of gravity and weak SU(2) interaction in a model that is invariant under the Spin(4, 4) group is studied. For this purpose, consequences of the multicritical-point principle, which admits the existence of two degenerate vacua in the Standard Model, are considered. Also, the existence of a visible and an invisible sector in our Universe is assumed.
