The distribution of matter in the late time, evolved, Universe is sensitive to many aspects of fundamental physics. The evolution of the largest scales gives us constraints on the expansion history of the Universe allowing us to test various cosmological models. On smaller scales the growth of density perturbations allow us to constrain alternative gravity scenarios and exotic dark matter models. In this talk I will review some of the recent successes that optical galaxy surveys have had in these regards and look to the future for surveys like the Dark Energy Spectroscopic Instrument (DESI). I will also touch on the prospects for future radio observations of the neutral hydrogen content in the Universe at high redshift. In particular focusing on some recent work I have done in Axion dark matter constraints from a realistic Square Kilometer Array (SKA) phase 1 type survey.
