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? Submitted by skovalen t3_124n2sg on March 28, 2023 at 12:23 PM in askscience 40 comments 132

You can't reach fields anywhere close to the Schwinger limit with charged walls, so again, this has nothing to do with walls.
