Air typically has a very high but non zero resistance. Given that air is just a medium, and that space is also just a medium, does the vacuum of space have a fundamental constant of electrical resistance, or is the electrical resistance of space truly infinite? How is this proven one way or the other, or can it even be proved at all realistically? Given that space has charged particles popping in and out of existence, my hypothesis is that space does have a finite value of electrical resistance, although it is extremely high. A high enough voltage could polarize charged particles in space and possibly cause a current to flow. Assuming you had limitless voltage, could you make any current flow across two points in vacuum space?
