No there isn't. There's a bunch of evidence that the current model used for cosmological dynamics (Friedmann's equations) don't work unless there's a lot of undetected stuff called dark matter. Until someone rules out stuff like using the full nonlinear Einstein equations vs Friedmann equations, or that the presumption of homogeneity/isotropy is wrong, (there's more stuff here that hasn't quite been excluded by observation) then the best we can say is that "We need some extra matter called dark matter for the standard cosmological model to work"
