The aim is to develop a dynamical dark energy model that incorporates axial torsion and makes falsifiable predictions about cosmological phenomena.
Derivation of a dynamical torsion energy density from axial torsion-scalar mixing.
Modeling the observable universe as a gravastar shell with unique packing arrangements.
Quantitative predictions about tensor-to-scalar ratio, neutron dipole moment drift, stochastic gravitational waves, and Hubble constant gradients.
Tensor-to-scalar ratio derivation ranges from 3×10−6 to 3.2×10−3, testable by LiteBIRD.
Neutron electric dipole moment drift predicted at less than 2.2×10−27 e⋅cm/yr, testable by n2EDM.
Stochastic gravitational wave background characterized at nHz frequency, testable by IPTA.
Hubble constant gradient expected at approximately 5 km/s/Mpc, testable by DESI/Euclid.
