Existence cannot represent its own complement, or it would be inconsistent, because it wouldn't be itself. Furthermore, and this is extremely important:
EVERYTHING THAT EXISTS IN THE UNIVERSE IS COMPOSED OF ENERGY
No particle is fundamental. All particles are composed of energy. In this case, I am using the term energy in its broadest possible scope, to include all types of energy, not just the observable kinds. In other words, by the term energy, I mean all types of quantized energy, all types of quantized dark energy, all types of virtual energy, all types of dark virtual energy, the quantum vacuum, and the singularity. Each different type of 'particle' is actually a localized quantum energy field composition with a specific type of quantum field configuration. Its quantum field composition and configuration gives each particle the properties we associate with particles.
The totality of energy in the universe (of all types combined) is a conserved quantity. It is impossible to destroy any energy, let alone all of it. Energy can be transformed from one form to another, including between forms that are observable and unobservable, but none of it can ever be destroyed. In metaphysical terms energy is the arche. In philosophical terms, it is the fundamental 'substance' that composes existence.
Since everything in the universe is composed of energy, that means zero energy, and thus nonexistence, is not part of the universe. Nonexistence is an inconsistent concept relative to physical existence. Even if we remove every particle from a region of space, and cool it down to absolute zero temperature, and shield it from all external energy fields, the resulting vacuum is still full of virtual energy and virtual dark energy. It still contains the quantum vacuum energy. Spacetime itself is composed of energy. There is simply no way to remove all energy from anyplace, let alone destroy all energy in the universe. Where would it go, universe 2? There is no such thing. The universe is everything that exists. There can only be one everything. Since the empty set is an isomorph of nonexistence, the empty set, and by extension the concept of zero, is also not part of physical existence, and is thus inconsistent with physical existence.
Information is AnthropocentricFor all x in the universe, x must exist BEFORE it can be observed, measured, or represented in terms of information. That means existence cannot be composed of information without reversing the order of cause and effect. That means the "It from Bit" hypothesis in quantum physics, that at its deepest levels, existence is composed of information is false, because it requires a reversal of the order of cause and effect.
Examine the causality graph between energy, existence, observation and information. Existence is composed of, and thus causally depends on, the existence of energy. Observation depends on energy and existence. Information depends on energy, existence, and the observation of both.
Observation depends on existence and energy. If there is no existence, there is nothing to observe, no observer to observe it, and no energy for the observer to use to represent anything with. Energy and existence can exist without observation, but observation cannot exist without energy and existence.
Information is dependent on observation, existence and energy. Energy is a potential difference in an energy field. Those potential differences create charge imbalances, and thus disturbances in the energy fields that compose spacetime, matter, and all forces. Those disturbances form travelling waves that propagate through spacetime. Those waves are signals. We interpret those signals as carrying information. More specifically, observers measure the resulting localized potential differences in the energy field that composes a signal when those potential differences cause changes in the receptive field of a sensory transducer, and use the (usually amplified and signal conditioned) potential differences to construct the representation of information which they then use to represent the associated part of existence indirectly. In other words, once again, I point out that existence is not composed of information. Only our indirect representation of existence is composed of information.
Heisenberg UncertaintyIn fact, the meaning of information, and its reduction in uncertainty is only a reduction in uncertainty relative to the observer that interprets the meaning of the information. The meaning of information, and its uncertainty is in the mind of its interpreter. Of course at quantum scales, the energy required to take a measurement is a substantial fraction of that which composes the localized field being measured, so it changes that field, making subsequent measurements of the same localized field uncertain. Nevertheless, the uncertainty is part of the information we use to represent existence, not part of the energy that composes existence itself. Physical existence itself has no uncertainty. No representation that is complete and consistent in the universal domain can have any uncertainty. Mathematically speaking, uncertainty can only exist in incomplete and/or inconsistent representations. In simple terms, this means information, observation, and measurement are unreliable tools for representing existence, because they are anthropocentric. They are incomplete, inconsistent, and uncertain. As long as physics relies solely on them, it too will remain incomplete, inconsistent, and uncertain.
Physical existence is a self-generated direct mathematical system that generates all of itself directly from the transfinite recursive composition of symmetric potential differences in the singularity. In other words, instead of representing numbers from the transfinite recursive composition of empty-sets, nature represents existence from the transfinite recursive composition of symmetric potential differences in the singularity. In effect, physical existence is a faithful isomorph of the complex number system, except there is no zero. Zero is replaced by the infinite singularity. The infinite singularity acts like an inaccessible cardinal. In addition, nature's equivalent of the complex numbers starts with very large potential differences at each big bang (there are an infinite series of big bangs...), and the magnitude of the potential differences decreases over time as spacetime cools and expands and energy and dark energy compose higher and higher order forms of matter and energy. Eventually, the energy in the quantum vacuum will be exhausted and the expansion of spacetime will slow and then reverse. More and more black holes will form, and space, time and the quantized energy forms will be converted back into their infinite forms, where they will remain trapped in the singularity, until the omega black hole consumes all remaining spacetime in the universe, causing a collapse of its own gravitational field, and the subsequent initiation of the next big bang. Hence, in this model, the universe is an infinite series of big bangs. Between each big bang spacetime undergoes a short period of exponential inflation, followed by a long period of expansion, then an exponential increase in the rate of black hole production near the limit of spacetime expansion resulting in a short period of exponential deflation, followed by a gradually decelerating asymptotic deflation until the omega black hole finally consumes all remaining spacetime in the universe and causes the next big bang.
The result is a symmetrically self-limiting four dimensional pentachoron simplicial complex spacetime lattice composed from a cumulative hierarchy of complex tensor valued quantum energy fields with Gaussian integer coefficients. (The space between the quantized lattice points is filled by complex and imaginary fractal dimensional non-quantized complex tensor fields with complex real non-integral coefficients that represent the composition of virtual energy and virtual dark energy fractal strings in the quantum vacuum fields). Thus we get time, space, all forms of energy, matter, and complex Hilbert Space tensor hierarchies of quantum field compositions. Time and space both exist physically. Since they both exist, they both must be composed of energy. Spacetime energy field compositions of energy and dark energy compose photons and the elementary particles, and those and their relations compose larger particles and particle systems. We get whole part hierarchies of composition at all spacetime scales above the quantum scale, but because the symmetry of pentachoron simplices is topologically self-dual, the dimension of spacetime never increases beyond the fourth dimension. Instead, as quantum bubbles of temporal energy and anti-temporal dark energy are created via ongoing spontaneous particle pair creation out of the quantum vacuum, it causes the ongoing expansion of four dimensional spacetime. We get time and space, the arrow of time, and the fact that cause precedes effect at all spatial scales above the quantum scale.
Subspace - A New Model of the Quantum Vacuum
Below the quantum scale, spacetime and order break down because virtual energy and virtual dark energy have an imaginary dimensional fractal structure below the quantized unitary imaginary dimension of time, so it has no fixed measure, and time, space, quantum states, and order do not exist. I call the fields that result subspace. Photons and the speed of light are meaningless in subspace. Subspace is filled by the infinite forms of energy. It is infinite because it lacks a measure, not because it is infinite in quantity. Strictly speaking, without a measure, the concept of quantity is undefined and does not exist. Changes can propagate through subspace instantaneously because time and distance have no meaning there. This is what enables the 'spooky action at a distance' observed in entangled quantum systems. It also explains why quantum state changes occur in quantum leaps in zero time.
Physical Existence is Complete and Consistent
Since the universe is everything that exists, it also has to be complete. That means the universe and everything that physically exists in it is complete and consistent. That means the universe is the union of the finite and the infinite. The quantized forms of energy and dark energy represent the existence of the finite, and the non-quantized forms of energy represent the quantum vacuum, virtual energy, virtual dark energy, and the singularity. In effect, there is a one-to-one isomorphic mapping between the complex field (with the singularity replacing zero), and physical existence. In essence, physical existence itself is a kind of direct mathematical complex number system. The universe as a whole is thus both complete and consistent in the universal domain. The universe is the union of the finite and the infinite, and all relations between them. It is only our indirect representation of existence, based on information, that is incomplete, inconsistent, and uncertain.
