Hi,
In a vacuum there's no particle to form a current (with the exception of capacitor charge&discharge, we are talking about DC current& static field here), so could the absolute vacuum conduct electricity? I heard that with high enough electric field, virtual particles could form and then a current can flow in absolute vacuum. How high this field is? And what happen with even higher electric field?
