TFNR - A box full of nothing

Is it possible to create nothing in a box? Progressively remove all the content until obtaining a state of non-existence? What should we eliminate to achieve such a condition?

Let's say at once that nothingness is a state - "non-state" that cannot be created. It would not even be possible if we had infinite knowledge, unlimited energy and all eternity.

Surely it would not be possible to reach nowhere inside a box, a box contained in a Universe. Inexistence and existence exclude themselves. These are incompatible conditions. And, in any case, global, universal, total conditions / states. Reality exists in its totality or does not exist. Nothingness and the group of partial / total states of Emptiness / Somethingness / Wholeness are self-excluding. Either there is nothing, or there is everything. An evolving whole, which can have different degrees of extension, quantity and quality, of development, but, in any case, it is everything, the everything.

The only way to obtain nothingness would be to eliminate the Source of Reality, which incessantly produces the Elementary Events which constitute the most basic "substance" from whose organization everything that exists is composed. But in this case, by eliminating the Source, instantly all Reality would cease to exist, and no conscious being could be aware of it.

For pure exercise, even knowing that we would not be able to reach the goal, let's try to imagine what we should remove from the box at least to get closer to nothing:

• air (molecules and atoms)
• some (maybe many) isolated sub-atomic particles:
  • electrons
  • protons as "hydrogen nuclei"
  • some neutron produced by the decay of some radioactive element present in the air, in the materials of the environment that hosts the box (the concrete of the walls of the lab, etc.)
  • many neutrinos passing through the earth
  • particles of cosmic rays coming from space
• radiation of various wavelengths:
  • radio waves from the cosmos, from broadcasting stations, etc.
  • micro waves of thermal radiation, from the sky, etc.
  • light waves
  • ultraviolet waves
  • x-rays from space, from physical phenomena
  • gamma-rays from space, from physical phenomena, annihilations, decays, etc.
• dark matter / energy
  • the box, and the earth that hosts it, are part of a dark matter halo that includes the solar system, in turn included in a wider halo that includes this part of the Milky Way, included by the global halo that hosts the visible structure of our whole galaxy, included in huge halo that hosts the local group of galaxies, then more and more halos of the cluster of galaxies, superclusters, and so on, a huge amount of dark matter, and the related counterparts of dark energy
