A common misconception is that a universe uniformly filled with charge must produce a zero electric field everywhere because equal amounts of charge exist in all directions. We examine this idea using Gauss’ law by constructing infinite charge distributions that respect different symmetries from the outset. When the distribution is built with spherical symmetry by expanding uniformly charged spheres, Gauss’ law yields Constructing the universe instead through an infinitely long charged...
