We consider a discrete Gaussian free field h in a two-dimensional box of side length N with Dirichlet boundary conditions. We study the Liouville first passage percolation, i.e., the shortest path metric where each vertex is given a weight of exp(\gamma h) for some positive parameter \gamma. We show that for sufficiently small but fixed gamma, with probability tending to 1 as N goes to \infty, the dimensions of all geodesics between vertices of macroscopic distances are simultaneously strictly larger than 1.
