If you find that amazing, contemplate for a moment how nuclear fission and fusion work and the amounts of energy involved there. Apart from a few comparatively exotic things (black holes, neutron stars, etc.), some of the largest force densities that exist are all around us in atomic nuclei (of course, those forces also decay very quickly with distance, but that's a different matter).
