According to current physics, is vacuum still something or nothing?

That could be alternating current, rather than the axiom of choice.

And I thought "almost certain".

Acronyms are a.c. (always confusing).

By something, with critical thinking, I define something as that which is contained within boundaries or limits. Basically that which is finite. What is synonymous with something is object such as an atom, "fields", etc. Anything with physical boundaries.

Well... Cosmologists think that Universe is actually infinite, so by your definition Universe is not something. The same with fields, since these are defined on whole "infinite" spacetime.

Perhaps absolute nothing is still something? Perhaps the absolute nothingness of the vacuum is still something (i.e. a vacuum). What we need is absolute nothing that is not something at all.

As it is much ado about "nothing" and seemingly going in (largely philosophical) circles, this thread will remain closed.
