Objection, Your Honor! Don't know if electron quasibeams (see comment above) can be done, but the "a beam consisting of a lack of something is not possible" in the current explanation is too wide. Think of antisound devices! I think a "vacuum beam" going through normal gas pressure is very possible. And what about the Meissner effect, which could be seen as a beam of absence of a magnetic field?

I must admit... I'm not entirely convinced that one _couldn't_ build an electron hole beam. It would probably be called a quasibeam, but I think it could be done. 162.158.175.61 05:11, 19 August 2023 (UTC)
Would an electron "vacuum" be an electron hole gun? Barmar (talk) 05:30, 19 August 2023 (UTC)
Is it worth mentioning that "pewpewpew" was one of the incorrect pronunciations of Perseids in 2414? Barmar (talk) 05:34, 19 August 2023 (UTC)
