In my talk I will first give the background on the physics of neutrinos and how it affects cosmological observables. I will then move to describe how many comsological experiments have put bounds on cosmology and more specifically the new upper bound that we have placed on the neutrino mass at UCL by looking at the clustering of Large Red Galaxies (LRG's). I will then move to show how future cosmological experiments will hunt the neutrino mass to an accuracy where we will for sure detect it unless we are swamped by systematic effects.
