The evidence for mass discrepancies in galaxy and galaxy cluster is beyond doubt. The leading explanation posits the existence of large amounts of dark matter particles dominating the mass of the universe. However, the absence of direct detection of candidates so far in spite of a large and comprehensive search program, the consequent tight constraints on the possible candidates properties, and the elusiveness of SUSY, a natural framework for many candidates, is straining the dark matter scenario. Here, we discuss an alternate solution to the galactic mass discrepancy. Our Ariadne's thread will be QCD, the theory of the strong nuclear interactions, and the intriguing parallels between astronomical observations -controlled by gravity- and the phenomenology of the hadronic  structure -controlled by QCD. These similarities may come from the analogous structures of General Relativity and QCD. If so, part, or even the entire, mass discrepancy may be due to unaccounted non-linear dynamics in galaxies. We will present some evidence supporting this alternate approach to the Dark Universe.
