Reply to comment by pewpewbrrrrrrt in How does an ideal vacuum have a dielectric breakdown voltage of 10^12 MV/m? If there is nothing there, then how can electricity pass through it? by skovalen

Ideal vacuum means there are no atoms/particles. Fields by definition are always there in all of space.
