Reviving a small simulation (2D in Julia) to show how the onset of cosmic structure formation can essentially be captured by the Zeldovich approximation - meaning you just keep displacing the initial distribution of particles following the path traced by the initial tiny gravitational perturbations, which are imprinted in the initial conditions.
Actual N-body dynamics will take place only at the first crossing of streams of particles (in filaments, halos..)

Simulated trajectories of ultra high energy protons with energies from 1e18 to 1e20 eV injected by galaxies at z=0.05 and propagating across the magnetised cosmic web.
