Well, probably not, but …
How is this possible? It’s like the Universe itself doesn’t understand our idea of “nothing” at all; if we were to remove all the quanta of energy from our Universe, leaving behind only empty space, we would immediately expect that the Universe would be at absolute zero: with no energetic particles anywhere to be found. Yet that’s not the case at all. No matter how “empty” we artificially make the expanding Universe, the fact that it’s expanding would still spontaneously and unavoidably generate radiation. Even arbitrarily far into the future, or all the way back before the hot Big Bang, the Universe would never truly be empty. Here’s the science of why.
No matter how clearly in your mind you’re capable of envisioning an empty Universe with nothing in it, that picture simply does not conform to reality. Insisting that the laws of physics remain valid is enough to do away with the idea of a truly empty Universe. So long as energy exists within it — even the zero-point energy of the quantum vacuum is sufficient — there will always be some form of radiation that can never be removed. The Universe has never been completely empty, and so long as dark energy doesn’t decay entirely away, it never will be, either.

But wait. If it was truly empty, it would not exist, right? What we mean by the “universe” is everything that exists. So, if it’s “empty,” nothing exists.
Of course, it could always exist as an abstract idea but then it must be the abstract idea of a Being in another dimension.
Or are we missing something?
In 2019, Ethan Siegel also wrote about nothingness, explaining “how we can “get a universe from nothing.” That must have been a different nothing.
