   empty space governed by quantum mechanics (or any other laws of physics, or even just the laws of physics by themselves) is not nothing, and not even an “example” of nothing (whatever an “example of nothing” means), but something.

   Apr 26, 2024 · Practically all of the matter we see and interact with is made of atoms, which are mostly empty space. Then why is reality so… solid?

   What is a completely empty space?

   • In the dictionary, the proper word for a completely empty space is void. So, it is to the void that we turn as the complete absence of matter. Imagine that we had a super-pump, capable of sucking out every single air molecule from a bottle. (Of course, this has to be an imaginary perfectly rigid bottle, for otherwise it would implode.)

   Is empty space a real thing?

   • Likewise, empty space is conjectured to be quite complicated. We know that the universe is very empty. The average density of space is about one atom in every ten cubic metres – far more rarefied than any vacuum we can achieve on Earth.

   Does physical reality have empty space?

   • Physical reality is now seen as consisting of fundamental fields and their excitations. There is no such thing as empty space. Nobel laureate Frank Wilczek wrote an excellent popular book on this view, The Lightness of Being.

   Is there any property associated with 'nothing'?

   • There can be no property associated with "nothing" for that would be a contradiction. And, from a QFT perspective, the vacuum is a state of something. Only a thing can have states, and only a thing can be described in terms of physical law. Intuitively, since "Nothing" isn't a thing, there is no physical law that can apply.

   Does empty space have an energy density?

   • According to GR, "empty" space can have an energy density (even if it's zero). There can be no property associated with "nothing" for that would be a contradiction. And, from a QFT perspective, the vacuum is a state of something. Only a thing can have states, and only a thing can be described in terms of physical law.
