I get it, but my thoughts are simple because Astrophysics is not my field of science and I’m just a half brain Economist and a degreed man in psychology which really leaves me out of the quantum world. Since the brain functions in the way it does I can throw in my penny of thoughts. Early models depicted electrons as particles that orbited the nucleus, much like the way satellites orbit Earth. Modern quantum physics instead understands electrons as being distributed within orbitals, mathematical descriptions that represent the probability of the electrons’ existence in more than one location within a given range at any given time. Electrons can jump from one orbital to another as they gain or lose energy, but they cannot be found between orbitals. One can say whatever they wish in regards to areas that can’t be proven is like having an argument over dark matter, why do it matter? Empty space is just empty space until someone tries to make sense of it. Isn’t the reason why we have so many religious believers in the world?
There’s no such thing as empty space, unless you mean by empty space what we mean in everyday life (“the room was empty,” “I emptied the bottle”). To physicists, “empty” space is kind of made up of a sea of subatomic particles jumping into and out of existence.
