Abstract

Our proposed fractional cosmological framework aims to resolve the issue of synchronicity in the age of the Universe. The approach involves building a novel $\Lambda$CDM model based on the semiclassical limit of fractional quantum cosmology. By focusing on the corresponding semiclassical limit, we demonstrate that the Friedmann equation, and hence the Hubble time, are dependent on the L\'{e}vy's fractional parameter $\alpha$. This parameter is associated with the concept of L\'{e}vy path in the corresponding quantum cosmology of the model. We then use recent observational data to show that the dimensionless age of the universe does not necessarily need to be close to one, as is the case with the conventional $\Lambda$CDM model. Instead, the age can take on larger values that depend on the parameter $D=2/\alpha+1$. This parameter represents the non-locality attribute of the fractional derivatives.
