As far as I know, when the universe was born, it was essentially an electrically charged soup of particles. Free atomic nuclei and free electrons were everywhere, since the temperature for a few hundred million years was far too hot to allow electrons to 'permanently' bond with the free atomic nuclei. So for quite a while in there it was an electromagnetically opaque universe, until things cooled off enough to allow the first elements to form.
