Could the quantum-scale version of the altermagnetism, or gamma rays, form dark matter?

Alternamagnetism is a phenomenon. The magnetism is inside the object. There is no magnetism or electromagnetic interaction outside the object. Altermagnetism is one of the things that can cause another question. Could there be a similar effect in the other three fundamental interactions? Could there be a matter that is not visible and for which only known interaction is gravitation? Could this alter material explain dark matter? The quantum field that spins very fast could make it possible. 

That the matter itself turns invisible. A fast-spinning quantum field that moves away from electrons and protons can just push those waves back to the particles or the atom’s core. In the model of the De Sitter universe, the universe itself is surrounded by a divergent horizon. The information can never. Travel through that horizon. The effect is similar to a car that travels 100km/h. Then another car. Impacts that car from the back. With a speed. 101km/h. 

The impact speed is 1km/h. In the same way, if the horizon is a shockwave that travels 80% of the speed of light, and the photon impacts that field at the speed of light. The impact speed would be only 20% of the speed of light. This means that the photon’s energy level is not high enough for it to travel through that field. So could this kind of thing surround some particles or atoms? 

Of course, black holes are invisible. But. In the case of altermatter or dark matter, the field around those particles closes wave movement and photons in the quantum field. But is this possible at the quantum level? 

The wormhole, a tunnel through spacetime, can transport energy out from a particle so fast that the particle will not send wave movement or photons around it. 

Could the coherent gamma-ray beam transport so much energy away from the atom’s core that all photons from the electron shell travel into the atom’s shell? The gamma beam takes energy out of the atom’s shell. And the gamma-effect must not continue all the time. It’s enough that those gamma-rays keep the atom’s core energy level so low that electrons start to travel in that atom’s core. 

Another thing that can make particles or even atoms invisible is the opposite or mirror version of the electroweak interaction. In electroweak interaction, the weak nuclear force sends an energy impulse to electrons that orbit an atom’s core. And then those electrons send photons away from the atom. Fission and fusion are part of that kind of reaction. In the mirror version, something takes energy out of the atom’s core. 

The idea is that something changes the atom’s core energy level to lower than its electron shell. This should cause electrons to transfer photons into the atom’s core. If photons travel only into the atom’s core, that makes matter invisible. The problem is where the atom’s core puts that energy? 

The answer could be in the extremely short-wave coherent gamma rays. Those gamma-rays can act like a thermal pump, which transports energy out from the atom’s core. This thing. It can keep the atom’s core energy level so small that it makes energy travel into the atom’s core, and then that gamma-ray string. It can transport energy in a direction that the observer must look straight into the gamma-ray beam.

Could string theory be the gate to the TOE (Theory of Everything) and GUT (Grand Unified Theory)?

String theory. The string model is one of the attempts to explain the universe. This theory could explain almost everything. The mainframe of this theory is simple. The entire universe is formed of the strings. Those strings form matter as we know it. There are multiple internal structures. In the string model. And those strings explain things like the universe’s expansion like this. Strings that are actually tornado-shaped structures in the quantum fields of the universe. They transport energy to the edge of the universe, and that energy pushes its outer edge farther. 

This makes space in the universe. And that space pulls those superstrings open. Then those superstrings start to leak. Then they release energy or wave movement that travels through them. This means that. Every single superstring is actually a wormhole, a tunnel through space and time. When the universe starts to expand, those superstrings send energy into space.

And that energy would be the dark energy. The idea of the wormhole is that. Energy pushes information through it. The wormhole, or energy tornado. It denies. That energy leaks to the universe. When a particle, like a photon, travels through the wormhole, it stays young. Its energy level is the same as it was when it went to the wormhole. The expansion of the universe turns quantum fields weaker, but when the particle travels in a wormhole, the wormhole will not allow the particle’s energy level to decrease. This means that when a particle comes out from that string or wormhole, it releases more energy than it should. And that increases entropy in the system. The problem is that there is no physical evidence of the strings or wormholes. 

If there is a quantum-sized black hole or graviton in each particle. That thing can explain the form of the superstrings. When those hypothetical gravitons impact, they follow similar trajectories. As regular-sized black holes. This means that those graviton impacts can form the spiral-shaped structure that is the hypothetical superstring. 

Those quantum-sized black holes can form the structure. That looks a little bit like a pearl necklace. And if we want to use normal-sized (Stellar or supermassive black holes) as a model, there would be. A ring-shaped. Energy rings around every pearl. Those pearls are the halos of those quantum-sized black holes. Which could be the same as the hypothetical graviton. And their transition disks. Could cause those rings. The next thing that reseachers must do is to prove the existence of those structures.  

In one model. Those strings. Are not. So-called solid structures. There are models that superstrings are series. Of the wheel-shaped structures. In theoretical models. Those strings form around quantum-sized black holes. This means that. In every single particle in the universe is a quantum-sized black hole. The annihilation reaction that releases. Very high-energy gamma-rays. Could be similar. To the reaction that sends gamma-rays. In the black hole collimations. The gamma-ray burst forms when those black holes’ halos impact each other. That impact forms those gamma-ray bursts. 

So, when an antimatter particle impacts with its mirror particle, those particles turn into energy. The difference. Between matter and antimatter particles is their spin direction. That means those particles interact in a similar way to black holes when they impact. This means that, if the elementary particle is the quantum halo around the quantum-size black hole. That means that antimatter is the quantum halo that surrounds an opposite-spinning black hole than the matter.

And maybe dark energy is the thing that forms. When those antimatter and matter particles impact. First, the particle shells impact, and that sends the gamma-ray burst. Then their core, their hypothetical quantum-size graviton black holes' impact, and the energy that this impact releases could be covered by the flash of the particle’s shell. Or when those gravitons or quantum-sized black holes impact, they could follow similar trajectories as normal-sized black holes. This thing can form a spiral-shaped structure in the quantum fields. that can form superstrings.

Why can't we fit quantum models and gravity together?

Electroweak interaction (Or electroweak mechanism). And its effect on gravity. And the electroweak interaction effect in the Grand Unified Theory (GUT) 

“In particle physics, the electroweak interaction or electroweak force is the unified description of two of the fundamental interactions of nature: electromagnetism (electromagnetic interaction) and the weak interaction. Although these two forces appear very different at everyday low energies. The theory. Models them as two different aspects of the same force. Above the unification energy, on the order of 246 GeV, they would merge into a single force. Thus, if the temperature is high enough – approximately 1015 K – then the electromagnetic force and weak force merge into a combined electroweak force.” (Wikipedia, Electroweak interaction)

Is it possible that gravity is not one single force? Could there be some other phenomena that interact like gravity? Things like a cosmic void. They can cause a similar effect to gravity. 

In the electroweak reaction. The atom core. It sends an energy impulse to electrons. This energy impulse loads extra energy into those electrons. And then those electrons send photons. So, if we want to have a strong interaction with that process. We must say that gluons, the strong interaction transporter, send an energy impulse to the proton and neutron quantum fields. 

That energy impulse loads energy in those quantum fields. We see that energy interaction. As a weak nuclear force. Then those protons and neutrons send their extra energy into the electrons. When electrons send a photon. For a short time, there is a quantum low-energy area, or quantum low-pressure, around those electrons. 

The same type of quantum low-pressure form. Around protons, neutrons, and quarks, when they sent photons. And in that process, the electromagnetic fields that fill that quantum low-pressure region. It can transport particles and wave movement with it when it fills that point. This model. Increases the electroweak mechanism to all other fundamental interactions. 

Hunting of the graviton. Missing gravity transportation particles. 

If the graviton exists, that explains why gravity is so special. It explains the black holes as giant gravitons. The ultimate form of the hypothetical quark stars. In that model, the black hole forms when the internal structures of the singularity strip quantum fields from around gravitons. In this mode. The graviton. It is a quantum-sized black hole. And all elementary particles are bubbles that form around gravitons. 

Theoretically, making gravity models is easy. We can say that particles spin and bind energy to them. But then we are in trouble: how to prove that model? The way to prove this model in real life is more complicated. Gravitation is a weak force. So, the other three, electromagnetism and weak forces, will cover it. And because of that, quantum gravity is a very hard thing to observe. But then. We can see two very interesting questions. 

A) Could gluon be the mythic graviton? 

B) Could gravitation be more than one effect? There is a very long list of things that could cause similar effects to gravitation. 

1) Cosmic voids. 

2) Electromagnetic shadows. 

4) Different energy levels in particles. 

5) Material evaporation. 

6) Electromagnetism and all three other interactions. 

7) Spiral-shaped electromagnetic fields. 

And many other things can cause things that seem like gravity. Sometimes some reseachers say that gravitation is only a virtual force. Or maybe gravitation is the strong nuclear interaction. And that means gluons could be the mythic graviton. The gluon evaporation could interact. Like gravitation. But could the gluon be the graviton?

The strong interaction. Affects very short distances. But strong interaction is actually a wave movement. And that means other forces. Weak and electromagnetic interactions cover that wave movement. But also. Other interactions. Like electromagnetism and weak interactions, they are things. That can form things that look like gravity. 

Another thing that can cause a similar effect to gravity is the quantum or electromagnetic shadow that forms. When electromagnetic waves hit the particle. The particle forms the electromagnetic shadow that causes energy to fall to that point. Those things can cause interaction that seems like gravitation. When electromagnetic fields move, they transport particles with them. 

And then we must look at gravitational waves. Those waves move at the speed of light. But those waves don’t require a field where they travel. And that makes them interesting. Maybe there is still an unknown energy field in the universe. But. If we think that gravitation is a very short-wave radiation, that wavelength is far shorter than even gamma-rays. 

We can ask whether the graviton exists. And then, why has nobody seen gravitons? The graviton. A mythic gravitation transporter particle would be a boson. Like all other force or interaction transporters. In some models. The graviton is the quantum-sized black hole. The idea is that. Graviton-particle could be the thing that forms all elementary particles. As I wrote at the beginning of the text. 

In this model, all elementary particles are like bubbles around those quantum-size black holes. If those kinds of particles are the source for gravitational waves, their size would be smaller than the wavelength of gamma-rays. This thing is one of the things that can explain many things. The evaporation of those hypothetical quantum-sized back holes could explain dark energy. Gravity centers are the clusters of gravitons. 

And black holes could be black. Because they are pure gravitons. In that model, the inner layer of the black hole is the denser graviton cluster. And that strips quantum fields away from gravitons that are at the outer cluster in the singularity. If the graviton exists. The black hole. It is the giant graviton. The ultimate version of the quark stars. But if that thing is real.  It requires that the graviton exists.

Could quark annihilation explain something about dark energy?

Could the answer. For the dark energy mystery. Be. In some process of particle evaporation, which is previously unknown? And could that thing be the quark annihilation? 

Cosmic voids and material evaporation are interesting things. When we think about comic voids and conditions inside them. There. Quantum fields are weaker than in other places in the universe. This causes a material evaporation effect. And the question is, can this effect release as much energy as annihilation? When a particle starts to evaporate. An atom loses its electron shell. That gives the atom core room to expand, and then the bonds between protons and neutrons will break. 

In that process, energy is stored in the bonds between protons and neutrons. This energy release could form the extremely small WARP bubble around the atom shell. In that process, the evaporation reaction. It can be faster than predicted. When those bonds between protons and neutrons release their energy, that causes an effect. They also release energy into quarks that form protons and neutrons. This causes an energy impulse that pushes those quarks farther from each other. 

Released. This releases free energy in the system. Then the neutrons and protons start to decay. Or they release their quarks. This can happen. When a weak quantum field lets quantum fields around quarks expand. This causes that. The distance between those quarks starts to increase. 

“Graphic of quarks annihilating (left green lines), producing a photon (middle line), and producing two muons (right magenta lines). Scientists detected these muons to gain insight into the quark asymmetry of the proton. Image credit: Paul Reimer, Argonne National Laboratory”. (University of Michigan, Study finds unexpected antimatter asymmetry in the proton)

Sooner or later, the distance between quarks is so long that the bonds between them start to break. The neutron decay is confirmed. Two down and one up quarks form a neutron. This means energy travels to the up quark. And this effect causes neutron decay. 

Proton is more complicated. Its main structure is two up and one down quark. The energy travels to those up quarks more smoothly than in a neutron. But there are also particle-antiparticle pairs in proton. When the proton’s quantum field starts to expand, that causes an effect in which those particles and anti-particles touch each other. This effect rips a proton. In pieces. This requires that the quantum field around the proton expands as much as it allows those particle-antiparticle pairs to touch each other. Normally, the structure of a proton keeps antimatter and its mirror particles away from each other. But when a proton expands, that allows those particle-antiparticle pairs to annihilate. 

In that case, those bonds between those three quarks also release energy that is stored in them. In this process, the situation is similar to that in proton-antiproton annihilation. In that process. The reaction releases energy that is stored in those bonds. And finally, quarks and electrons turn into wave motion.

So, when we think that there is too much energy in the universe, we must ask, could that energy form in this type of reaction? When we think about material evaporation. And its relationship with dark energy, we must realize one thing. When reseachers make their calculations, they should know and handle every stage of those reactions. In cosmic voids, the speed of light is higher than outside it. This means all particles travel faster than they do outside the cosmic void. When they hit the edge of the void, they release that energy into those quantum fields.

The new method for manipulating light with a Narwhal wave function breaks limits.

“Narwhal-shaped wavefunctions describe a unique way of confining light to extremely small spaces. The mode volume measures how tightly light is confined and affects. How strongly it interacts with matter. It is defined as the total electric energy spread across space divided by its peak value. These wavefunctions combine sharp local enhancement with rapid overall decay, allowing light to be compressed far beyond usual limits without energy loss. Credit: Renmin Ma et al.” (ScitechDaily, Scientists Break Light’s Limits With “Narwhal” Wavefunctions)

In photonic information technology, the system traps single photons into it. Then it drives information into those photons. As we know. The photon. It looks. A little bit like a wheel. Information is stored in that wheel as a form of wave movement. The big problem was. How to control those photons. The answer can be in the system that puts the photon into spin. That spin forms the spiral-shaped wave field in the quantum field. And that thing can act as a tool that allows control of light. 

This spiral-shaped wave function. It can also be used to transmit information between photons. The spiral wave field looks like the horn of a narwhal. The big difference between older technologies is that the system. It can use the laying photons. In this model, photons. They are in the position. Those bigger sides of photons are against each other. And that allows faster information transmission. 

Because the transmitting area is bigger. Or, as you can see from the lower diagram, the system. It can press information through the photon ring. When information is transported to the photon ring. And the wave movement travels through it. That copies those shapes into that wave movement. 

“The Narwhal wave function is a novel approach to confining light in small spaces.  It enables extreme, sub-diffraction confinement of light in lossless dielectric nanostructures, with an ultra-small mode volume. And that thing.Makes it possible to use that thing in new photonic communication. “The researchers also used these highly localized wavefunctions to develop a new imaging approach called the singular optical microscope. (ScitechDaily, Scientists Break Light’s Limits With “Narwhal” Wavefunctions)

“Comparison between a twisted lattice cavity and a singulonic cavity. Left: schematic and field distribution (in logarithmic scale) of a twisted lattice cavity; Right: schematic and field distribution (in logarithmic scale) of a singulonic cavity. The power-law divergence of the narwhal-shaped wavefunction enhances the electric field intensity by more than six orders of magnitude in the deep-subwavelength region. Credit: Renmin Ma et al.”(ScitechDaily, Scientists Break Light’s Limits With “Narwhal” Wavefunctions)

“By exciting eigenmodes within singular dielectric cavities, the technique generates tightly confined electromagnetic fields whose resonance shifts respond to very small structural details. This enabled a record spatial resolution of λ/1000. And allowed imaging of deeply subwavelength patterns, including the letters “PKU” and “SFM.” (ScitechDaily, Scientists Break Light’s Limits With “Narwhal” Wavefunctions)

These types of things are necessary for making the quantum network. The biggest problem with photonic communication is how to drive information into the single photons. In this layer, the system must be very highly accurate. Before this new model, the system used plasmons to press photons to the layer. This method was. A little bit too complicated. To create. The accuracy that the quantum networks needed.

The Tellegen effect. It can revolutionize network technology and stealth materials.

“For more than 70 years, the Tellegen effect has been something of an 'optics unicorn': a phenomenon well described in theory but practically impossible to observe because it is usually vanishingly weak in natural materials. Now, researchers from the University of Gothenburg, Aalto University in Finland, and Stanford University report what they describe as the first experimental detection of the Tellegen effect for visible light.” (University of Gothenburg, Scientists Finally Spot the Elusive Tellegen Effect)

Reseachers at the University of Gothenburg and Aalto University spotted the Tellegen effect in optical metasurfaces. First time in history. Researchers formed an elusive Telleren effect in the optical area. Reseachers rejected natural materials. They developed the synthetic metamaterials. And. That opened new ways to create the Tellegen effect in material. 

And before anybody can benefit from that effect, the systems and metamaterials must turn more advanced. The Tellegen effect is a very weak thing. But if that thing is possible. And the radio waves. They can turn into optical waves. And backward. That can open new paths for network and stealth technologies. Another thing is that. The question mark is: could that effect transform all optical wavelengths? 

The Tellegen effect means a situation. That magnetic field interacts with metamaterials. Reseachers used metamaterial. That involved nanotubes, and finally, they used a material. That was introduced above this text. The material consists of pyramid-shaped structures. The reason why this material makes the Telleren effect possible is that. Pyramids transfer wave movement out from the surface. When a wave movement travels at the sides of the pyramid. The impact at the top of the pyramid.

That impact can change. Those waves' wavelength. This effect can transform quantum networks and stealth technology. There is a possibility. That's the Tellegen effect. 

It can turn electromagnetic fields or waves into visible light. If the Tellegen effect is complete, and material is covered by a light-absorbing layer, the Tellegen effect. It can make a revolution in material research. But this thing. Can make a layer invisible. In some models, the Tellegen effect. It could transform visible light reflection into UV or IR reflection.  UV reflection makes an object “colder”. And it is not visible in IR sensors. 

The idea is that the identical wave movement that travels in the same spot from the four sides of the nano-pyramid can also form the quantum dot. The quantum version of the electric arc. In cases where there is a channel in the pyramid. And there is an identical quantum electric arc or virtual particle, which can also pull all energy into that low-energy part of this quantum dot pair.

Could material evaporation be? Behind the dark energy?

When we think about the matter and how matter evaporation binds energy, we must realize one thing. The evaporation. Just puts energy into motion. When we think of a situation where ice turns into water, we might think. This process will decrease the temperature. This is not actually true. If that melting process happens. In one place or one point. 

When things like polar icecaps melt, that process requires energy. That energy is coming from the equator. When polar ice melts. That pulls energy into the melting process. This causes an effect. The equatorial tropical area is expanding. This means that the melting ice pulls energy. From around the planet. Into it. 

So we can think. This model can also fit in the universe’s scale.  We can say that the edge of the universe could be the point where material evaporates faster than inside the universe. That thing. Causes an effect that makes energy travel to the edge of the universe. When the universe expands. That thing causes a situation. The quantum fields in the universe turn weaker. During that process. That expansion forms large holes in those quantum fields. 

Cosmic voids and material evaporation at the edge of the universe, and those cosmic voids can form the dark energy. Cosmic voids focus energy. And that can expand the universe. The cosmic voids can also form a virtual gravitational effect that pulls particles and energy fields into it. 

“The farther away we look, the closer in time we're seeing toward the Big Bang. The newest record-holder for quasars comes from a time when the Universe was under 5% of its present age. These ultra-distant cosmological probes also show us a Universe that contains not just radiation and matter (including dark matter), but also dark energy, whose nature is unknown. Many questions still remain unanswered at the scientific frontiers. (Big Think, Starts with a bang, What was it like when dark energy rose to prominence?)

“Simulation of the matter distribution in a cubic section of the universe. The blue fiber structures represent the matter (primarily dark matter), and the empty regions in between represent the cosmic voids.” (Wikipedia, Void (astronomy))

Conditions in cosmic voids are similar. As at the edge of the universe. Material evaporates. Or turns into energy faster in the cosmic voids than outside them. When particles evaporate, they send wave movement into the center of those cosmic voids. This thing means that energy reflects from the center of those cosmic bubbles. And along with particles that evaporate. At the edge of the universe, that thing forms the dark energy. Or free energy that destroys the universe. 

Material evaporation. It means a process. There, the material turns into energy. Dark energy refers to an unknown source of energy. And in the dark energy case. We should ask, what puts energy into moving? The answer to that problem can be found in the material evaporation. When material evaporates. It acts the same. Way as ice. This process binds energy. And then energy from the environment tries to fill that point. So when. We are searching for the source of dark energy; we should look at the edge of the universe. And. At the same time. We should look at the edge. Of the cosmic voids. 

When material evaporates very fast at the outer edge of cosmic voids. That releases free energy in the system. Most of that energy falls. Into the cosmic voids and then jumps back. From their center. When matter evaporates, it releases energy. That forms it. When we think about cosmic voids, we could think that maybe those cosmic voids could explain dark matter. If most of the energy that evaporating particles release falls into the cosmic voids, they pull matter and wave movement with them in the same way as a gravitational field pulls those things. So, that means. The cosmic voids can form a virtual gravitational effect. That acts like matter acts in gravity centers. This means cosmic voids can also act as a virtual gravitational center. If the cosmic void is deep or empty enough, it can start to behave like a black hole. 

When particles evaporate at the edge of the universe. That effect pulls energy out of the universe to fill the point. There. The matter or particles evaporate. This effect, when it happens at the edge of the universe, pulls quantum fields to the edge of the universe. That makes those fields weaker. This causes an effect. That increases the speed. To turn into a wave movement. This effect pushes the edge of the universe away. And that increases the speed of particle transformation. Into energy. or wave movement. This means that the cosmic voids and the edge of the universe. They can put energy into moving in the mysterious phenomenon called dark energy.
