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

This has nothing to do with walls.

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