The current standard cosmological paradigm is remarkably  successful at describing the distribution and motion of galaxies  on large scales (>10 Mpc). The talk will discuss part of the strong evidence for the standard paradigm,  but also argue that minor modifications might be inevitable. In particular, it will focus on constraints and implications of models with Violation of Lorenz Invariance and Breaking of the Equivalence Principle in the Dark Sector only.
