description: In the last decade, the constructive gravity programme was developed to expand Einstein's  derivation of general relativity to matter bearing a non-Lorentzian geometric structure. This  thesis studies the phenomenology of general linear electrodynamics (GLED), the maximal linear  generalisation of Maxwellian electrodynamics, and its corresponding gravitational dynamics. We  derive quantum interaction rules for GLED Dirac quantum mechanics to determine the decay  width of the Cherenkov decay of superluminar particles in vacuum. With this, we obtain two non-  Lorentzian parameters of the GLED geometry. We employ a weak Field limit of GLED gravity  in astrophysics, study the stability of symmetric gravitationally bound matter distributions and  the internal structure of stars. Using galaxy rotation curves, we are able to estimate ranges for  both additional gravitational constants arising from weak field GLED gravity. Finally, we derive  and solve the linear growth equation which governs the structure formation in the early Universe,  and calculate the bispectrum in tree-level perturbation theory.
