The imprints of the origin and cosmic evolution of our Universe are encoded in the cosmological large-scale structure. However, the action of gravity after billions of years has washed out this information. Moreover our observations yield only a discrete and distorted luminous fraction of biased tracers of the continuous underlying cosmic (dark) matter density field. How accurately can we model the biased galaxy distribution including redshift space distortions and nonlinear clustering?, How far can we undo gravity?, and How far can we recover the full phase-space information from such tracers?
