Abstract: The exploration of the novel physical consequences of the Extended Theory of Gravity in $C$-spaces (Clifford spaces) is continued. One of the most salient physical feature of the extended gravitational theory in $C$-spaces is that one can generate an $effective$ stress energy tensor mimicking the effects of “dark” matter/energy. In particular, it is found that the presence of the cosmological constant, along with a plausible mechanism to explain its extremely small value and/or its cancellation, can be understood entirely from a purely Clifford algebraic and geometric perspective. For this reason we believe that this theory may have important consequences in Cosmology and further research in Gravitation and Particle Physics.
