What is the concept of quantized vacuum? And what is the role of gravity in nature? And what is the relationship between dark energy and quantum gravity?

The concept of a quantized vacuum effectively acting behind the scenes as a medium for the strong and electroweak interactions, and gravity is not a new topic in science and physics, and was brought back decades ago by string theory and other quantum gravity theories. such as quantum loop gravity, gravitons or superfluid vacuum theory (SVT), all of which attempt to explain the origin of gravity. and all the other four known forces as intrinsic and intrinsic physical properties of the vacuum that many today believe that deciphering the vacuum is the key to answering great unsolved problems in physics such as the cosmological constant. Dark energy and dark matter can be said that quantum vacuum research is of great importance for the body to go beyond the standard model of particle physics research, the development of quantum field theory, and the development of cosmology.

these days. After matter and light, vacuum is perhaps the last frontier that we must conquer to understand the nature and fundamental level of the universe at its best. However, all these theories that attempt to explain the phenomenon of the vacuum limit themselves by using and obeying the speed of causality dictated by the visible speed of light c, the basis for explaining all visible matter and energy in our universe and their interactions. , but vacuum is not light. And not matter, it is the lack of these that does not necessarily translate into nothingness. The best clue nature gives us is that the vacuum is not nothingness, it is the bounded zero point energy (ZPE) and vacuum fluctuations (ZPF). And virtual particles flow in and out of the vacuum, which, however, contradicts the massive vacuum energy predicted by QED. Density is therefore the cosmological constant difference and perhaps the greatest unsolved problem in physics today. Therefore, the author here supports by ansatz the idea that by observing the ZPE and ZPF vacuum combined with the cosmological constant problem, we are only seeing the tip of the iceberg and most of the intact vacuum energy is hidden from us and inaccessible. Our device ZPF and ZPE hidden vacuum energy only shows that the "conversion" is not complete and is the Heisenberg matter. The Uncertainty Principle In this context, if this theorized untouched and untouched type of vacuum energy is hidden, outside our phase of spacetime and beyond ordinary matter and known light, it can be assumed that our known physics must also be primitive and Essentially by violating the "holy grail" that is the speed of light in a vacuum, therefore, the absolute speed of causality is violated. After that, all ordinary matter and ordinary light energy and all four fundamental forces in our observable universe can be explained. And it worked as a manifestation in our spacetime of a locally disturbed and flawed vacuum. With the fourth force is therefore gravity

The only force that can be transmitted to us from the total energy of the hidden vacuum not only disturbed but intact. The latter spacetime also explains dark energy and possible dark matter phenomena, and why these seem so elusive. However, proof of the superluminosity property for a hypothetical sub-Planck-sized vacuum quantum, possibly analogous to a boson, is a

A waste of work using well-known theories that forbid this in the first place because they are based on the c-speed limit.

Dear Abbas Kashani

That is an interesting topic, unfortunately there are not much active RG members who are familiar with the topic (as far as I know).

Vacuum is not a well defined concept. In the past vacuum was every volume without matter. But nowadays vacuum has another meaning too: vacuum is every volume in the universe where the local Higgs field is flat (no decreased scalars). The underlying idea is that rest mass needs local decreased scalars. That means that >99% of the volume of a Hydrogen atom is still vacuum space.

If we redistribute all the concentrated energy in the universe – atoms, molecules, objects, celestial bodies, etc., etc. – to the volume of vacuum space, the universal scalar field (Higgs field) is flat again. That means that all the scalars in the universe have exactly the same magnitude.

This enormous volume without matter is still “filled” with energy because the whole volume is tessellated by the universal scalar field (Higgs field), the universal 3D topological field (electric field) and its corresponding vector field (the magnetic field). At the moment that energy is concentrated by these 3 basic quantum fields (the creation of local matter) new forces are created too: the strong force, the weak force and the force of gravity.

So we cannot speak about quantized vacuum, because it is too limited. The quantization envelopes the whole volume of the universe. That’s why they mostly use the term “quantized space” (quantum gravity).

In a universe without matter the universal electric field doesn’t differ from the universal electric field now. So there are the continuous fluctuations of the universal electric field that create local amplitudes [C. Riek et al. (2017); “Sub-cycle quantum electro­dynamics”. Nature 541, 376-379 (2017). https://doi.org/10.1038/nature21024]. The linear propagation of the fluctuations of the universal electric field is the constant speed of light (c). The energy fluctuations itself are quantized and known as Planck’s constant (h).

Now it is easy to derive the mathematical (geometrical) property of the quantum of energy. Because our “model” is limited to the existing 3 basic quantum fields that tessellate the whole volume of the universe.

If energy is equal to volume, the acceleration of a particle must result in the increase of the volume of the particle. That is not what we observe. The shape of an accelerated particle changes, but not its volume (length contraction). Now there is only one possibility left: energy is surface area. In line with Einstein’s formula E = m c2 (if energy is volume, the formula have to be E = m c3).

However, how must we interpret the relation between energy and surface area?

Now your quantization of space comes into sight. Because if space itself is quantized, the volume of our universe has a structure and the units of the structure are the volume quanta of the universe. So every unit has a volume and a surface area. Although the surface area of every unit is a joint surface area with the adjacent units around. Therefore the 3 basic quantum fields represent the dynamical properties of the units of the structure of quantized space (also termed “discrete space”).

That is what they told us when we started our scientific education: physical reality is about the mutual relations between the observable and detectable phenomena (= dynamical properties).

With kind regards, Sydney

The ``quantized vacuum'' is the state that is annihilated by the annihilation operators of the excitations described by the theory. In flat spacetime it's unique, in curved spacetime it's not.

The role of gravity is in defining spacetime curvature. More specifically, in imposing invariance under general coordinate transformations=diffeomorphisms. It is this, defining, property of classical gravity that leads to the inevitability of spacetime singularities. How this symmetry emerges from a quantum theory of gravity isn't known, since a quantum theory of gravity isn't known.

Dark energy is well defined in classical gravity, where its effects can be described by the cosmological constant. What it means for quantum gravity isn't known.

Abbas Kashani ,

we have an example of "background energy" acting in the macro but most do not even consider as such because they did not see this as such...

Following a sort of Cavendish experiment set twin masses in deep space and let them go... you have a "system" of approaching masses till they collide and form just one. You have to assume potential energy transferred into the the "system" to justify the kinetics of their approach and after collision there is radiation emission.

Where such potential energy comes from ?

From the masses?

if one applies the invariance of rest mass and energy conservation it is not difficult to arrive at the necessity of the "background energy"....

To answer the question “What is the concept of quantized vacuum? And what is the role of gravity in nature? And what is the relationship between dark energy and quantum gravity”

- it is necessary before scientifically to define/understand what are really objectively existent “vacuum” and “gravity”, and further – what are really existent only in mainstream physics, first of all in Standard particle Model, QFTs, and further cosmology, “physical vacuum”, “true vacuum”, and “false vacuum”.

For that is necessary before to define/understand really scientifically what is the fundamental phenomenon/notion “Mater”, for what is necessary .also to define/understand what are other really fundamental phenomena/notions, first of all in this case “Space”, “Time”, “Energy”, “Information”, which all are fundamentally completely transcendent/uncertain/irrational in mainstream philosophy and sciences, including physics, - while all these phenomena/notions really can be really scientifically defined/understandable only together.

So really in mainstream physics really everything, i.e. “space”, “time”, “particles”, “fundamental Nature forces” – and so the Forces’ mediators – and so “charges” and “fields”, etc., are fundamentally completely transcendent/uncertain/irrational as well.

Correspondingly in every case when the mainstream addresses to any really fundamental problem, then result is completely logically inevitably is nothing else than unscientific/transcendent/mystic something.

Really Matter – and all other really phenomena/notions above - can be, and well essentially are, really scientifically defined/understandable only in framework of the Shevchenko-Tokarevsky’s Planck scale informational physical model, 3 main papers are

Including in the model it is rigorously scientifically shown that Matter’s ultimate base is the (at least) [4+4+1]4D dense lattice of primary elementary logical structures – (at least) [4+4+1]4D binary reversible fundamental logical elements [FLE], which is placed in the corresponding Matter’s fundamentally absolute, fundamentally flat, fundamentally continuous, and fundamentally “Cartesian”, (at least) [4+4+1]4D spacetime with metrics (at least) (cτ,X,Y,Z, g,w,e,s,ct).

The spacetime is fundamentally nothing else than some infinite “empty container” – which contains inside so just “vacuum by definition”, and both – the 8D space with metrics (cτ,X,Y,Z, g,w,e,s), and the 1D time dimension, ct, fundamentally cannot be “contracted”, “dilated”, “curved”, “quantized”, so on.

Everything in Matter exists and happens as some disturbances in the lattice, so in this case the notion “physical vacuum”, can be, in principle, be introduced, i.e. the case when the lattice isn’t disturbed everywhere, and that seems was just after the “inflation epoch”, when first version of the lattice was formed [more see the 2-nd link, section “Cosmology”], but after “Matter”, i.e. real particles and fields was/were created in the lattice, this notion looks as superfluous;

- while the mainstream physics “physical vacuum”,where in every space point all numerous in the mainstream “virtual fields” of all numerous “Forces”, and all “virtual particles” that are some “excitations of virtual fields” constantly and always for some mystic reasons and by some mystics ways appear and also mystically disappear/ “annihilate”,

- and further “false vacuums” that are some mystic “bubbles of state of “true vacuum””,

- really are nothing else than some fantastic mental constructions. Everything in Matter exists and happens only really

The thread is rather long already, so now
