  This proceeding is an introduction to cosmological applications of the
Lorentz gauge theory. It provides the ingredients for a unique, though yet
tentative $\Lambda$CDM theory of cosmology. The emergence of spacetime is
described by the spontaneous symmetry breaking called here the khronogenesis.
Space is then associated with the field strength of the antiself-dual gauge
potential, and gravity is associated with the self-dual field strength. In the
cosmological setting, khronogenesis seems to predict inflation. It is shown
that the Lorentz gauge theory allows the consistent description of spin
currents which could have important roles in cosmological phenomenology.
