The universe's dark second origin is unveiled.


"Dark matter may have sprung from its own “Dark Big Bang,” separate from the traditional Big Bang, with potential proof coming from future experiments detecting gravitational waves. Credit: NASA’s Goddard Space Flight Center/CI Lab, edited" (ScitechDaily, The Dark Big Bang: Unveiling the Universe’s Hidden Second Origin)

It's possible. That dark matter is the shadows in the Higgs field. But we cannot be sure about that. 

The evidence that the universe did not begin from one event is stronger. That means that the Big Bang was a series of events that included many forms and energy levels before the material and energy formed. The dark Big Bang is the model that there were material before the universe. The dark Big Bang means that the dark matter is released in its own event. And that is one of the most interesting theories in the world. If the dark matter formed in a different, unique event that means it would be hard to see that material even if it's similar to visible material. 

The reason for that is that the dark matter particles or their elementary particle size will be different from than visible material. That means the wavelength that the dark matter particles send would be different than the wavelengths that we see. The different origin of the dark matter is one of the ways how to close that mysterious interaction. The young universe was different than the modern universe. The temperature of that universe was higher. And differences between energy levels were lower than in the modern universe. 

That means the energy flow from higher energy levels was slower and that means in the very young universe other fermions than just up and down quarks and electrons could form "stable" particles. The thing is that the muons and top and bottom quarks should have the ability to form "similar" particles as up and down quarks and electrons. The fast energy flow destroys those structures in the modern universe. But in a very high-energy environment that kind of hypothetical material could be possible. But that cannot happen in the modern universe because of the short existence of those particles. That material requires higher energy and more stable conditions. 



The sombrero model tells how gravity destroys the material. A standing gravity wave surrounds all particles. That gravity wave is the low energy area around particles or other gravity centers. If the differences between the particle's energy level and the bottom of the energy ditch around the particle are high enough, energy travels out from from particle so fast that it destroys it. 

When we think of models that gravity destroys the universe or all matter from inside it, we can think that the gravity ditch or gravity wave surrounds all particles. The gravity wave or lower energy area that forms the ditch around particles is the thing, that causes energy flow in it. The energy travels from outside and another energy wave comes from the particle inside that "sombrero". 

If the standing gravity wave or pothole is too deep particle vanishes into it. If we make a model where energy travels to that particle from above, that thing can cause reflection that covers the gravitation or energy pothole. Just like water that creates a roof-like form when we aim water dush to peg straight from above. The problem is that if the gravitational pothole is deep enough that causes a situation where energy travels out from the particle very fast. 

That thing rips their structure immediately. So can gravitation be the negative energy?  The idea is that. Negative energy is the energy that travels away from a particle. And the energy that travels into particles is positive energy. The determinator is in the energy flow direction. If the gravity wave is a lower energy point in the base energy field in the universe that means gravity itself or the energy flow that gravity causes is the negative energy.

Can dark matter be so-called virtual or quasiparticle?

The Dark Energy Spectroscopic Instrument, DESI tests Einstein's theories in 11 billion light years in the Universe. 


The dark matter hunters. 


Maybe the standing gravity wave surrounds all gravity centers. That means dark matter can be the standing gravity wave. And if a standing gravity wave forms a structure whose wavelength is too short for electromagnetic waves. That they can fill that energy ditch. The energy falls into those low-energy areas from their sides, and then they will impact in the middle of that wave. 

That causes an energy pike that sends wave movement around the universe. Sooner or later, that energy ditch or lower energy area fills. And that makes gravity waves weaker. The side-coming energy can deny gravitational interaction between particles. 

And maybe that is the dark energy. The thing that makes gravity wave or lower energy area in the base energy field in the universe would be the particle. When the wave hits the particle, the particle stores a little part of that energy. And then, behind that practice, the energy shadow, low energy area, or energy ditch starts to travel through the universe. 

Dark matter is the mysterious part of the universe. Some researchers think that dark matter is a dark energy source. But that is only speculation. The dark matter hunting is interesting because there are galaxies there is no dark matter. But in some galaxies, there is dark matter. That tells that maybe the WIMPs, hypothetical dark matter particles can form similar forms as visible material. 

The interesting question is this: can dark matter follow the rule of centripetal force? Can fast-rotating material disks throw those WIMPs or the base energy field away from the structure? 

The problem is how the WIMP can be unseen. The material that only confirmed reaction with its environment is gravitation is mysterious. There is also so much dark matter that the most of material in the universe is invisible to us. The Dark matter can be quasiparticles with an energy level lower than a three-kelvin cosmic background. In a quasiparticle model, the electron or some other particles can be destroyed. That means electrons will leave a hole in the universe's base energy field. 

That makes it hard to see those particles. The dark matter and dark energy are a mystery. In some models, WIMPs can be the whirls or low-energy potholes in the Higgs field. In some models, the WIMP is a standing gravity wave. The idea is that all galaxies send gravitational waves that can be like traveling ditches in the base energy field in the universe. That means that those gravitational waves will impact near the galaxies with the other gravity waves. 

And that means that the gravity waves can be locked as standing gravity waves around galaxies and other gravity centers. And maybe that thing can explain dark energy. Or, at least lots of it. When we think that gravity waves look like traveling ditches the low energy points in the universe's base energy field. If that model where gravity waves are like traveling ditches that can cause a situation where energy starts to travel in that thing. 

The idea is that electromagnetic waves cannot fill that energy ditch, called gravity waves because the gravity wave's wavelength is so short. The gravity, or gravitational wave pulls energy into it. And if two energy waves impact each other in the middle of the energy ditch, a gravity wave can explain some part of dark energy. 

That thing can cause situations where that side-coming energy fields will fill traveling gravity waves. That means the incoming energy that faces the gravity wave from the point, where that wave begins can travel into that gravity wave and fill it. If that energy starts to fill gravity waves from both ends that causes an energy wave or standing wave in the middle of the gravity wave. The idea is that a gravity wave is so short that. Other wave movement types like gamma, X-ray, or other electromagnetic waveforms cannot fill it from above.

The neutrino fog can disturb dark matter observations.


"The race to find dark matter could grow more complex with high-energy neutrino interference." (Big Think, Signs of “neutrino fog” emerge, complicating searches for dark matter)

"Scientists have long hypothesized dark matter as an invisible force explaining galaxy rotations, yet direct detection remains elusive. Now, highly sensitive detectors are picking up hints of high-energy solar neutrinos — known as the “neutrino fog” — which could overwhelm potential dark matter signals. This new interference complicates efforts to detect dark matter particles, though alternative models beyond WIMPs may still provide viable detection paths."(Big Think, Signs of “neutrino fog” emerge, complicating searches for dark matter)

Neutrino fog means high-energy neutrinos that get their energy from other energy sources. Neutrino is one of the elementary particles, and it can travel through the entire planet without impacting anything. Sun and other stars create neutrinos in fusion reactions. The neutrino interacts with its environment as all other particles. 

Neutrino takes energy into its quantum field like all other particles. And when the environment turns into a lower energy level neutrinos send their extra energy as energy impulses. That radiation is the neutrino radiation. The birth process of that radiation is similar to neutron radiation in a neutron bomb. The idea is that the particle sends its extra energy as radiation, as well as, other particles. 

The difference between elementary and other particles like baryons protons and neutrons is that the elementary particle is "harder" and there is not so much space where the energy can go. Things like Higgs boson send radiation whose wavelength is the same as their size. The lifetime of those particles is very short and that radiation can be covered by radiation that other particles send. 


The neutrino fog can be used to create a neutrino laser. That system is extremely hard to create. 


Because neutrinos are hard to trap. However, if researchers can make the neutrino fog. And trap neutrinos in the tube. They can create synthetic neutrino beams that can be the most revolutionary thing in history. But near black holes, neutrinos orbit the event horizon. And there the material disk and radiation can interact with those neutrinos. And they can send that radiation. 

The thing is that neutrinos themselves and neutrino radiation can cover the interaction between still hypothetical weakly interacting massive particles, WIMP, and its environment. The only known interaction between WIMP and other particles is gravity. That forms an idea that maybe the WIMP is the stable quasiparticle. That means WIMP can be the hole or low energy point in the quantum field. 

WIMP could have other types of interactions but those interactions are so weak, that we cannot see those interactions. In some models, the WIMP is so fast fast-spinning object. That it creates a quantum bubble around it. The WIMP can be a string-shaped structure. The fast spin makes the electromagnetic vacuum around the spin axle. And that stretches the WIMP into the wire-shaped thing. That means the WIMP can send energy waves whose wavelength is so short and the altitude or power is so low that we cannot see them. 

The thing is that we cannot see static energy fields. We can only see the changes in the field. That means if the wave movement's wavelength is very small that means the object sends energy impulses very often, and we cannot see that energy impulse. When we think about the decay or destruction of the Higgs boson the Higgs boson sends its energy as all other particles. It sends a series of energy impulses. But it sends them in a so short time, that obeservers see them as one energy impulse.

Dark matter can form black holes.



"This artist’s illustration shows a rapidly feeding black hole that is emitting powerful gas outflows. Using data from NASA’s JWST and Chandra X-ray Observatory, a team of U.S. National Science Foundation NOIRLab astronomers have discovered this low-mass black hole at the center of a galaxy just 1.5 billion years after the Big Bang. It is accreting matter at a phenomenal rate — over 40 times the theoretical limit. While short lived, this black hole’s ‘feast’ could help astronomers explain how supermassive black holes grew so quickly in the early Universe. Credit: NOIRLab/NSF/AURA/J. da Silva/M. Zamani" (ScitechDaily, Defying Physics: Supermassive Black Hole Devours 40x Faster Than Expected)

"Astronomers using the James Webb Space Telescope discovered LID-568, a supermassive black hole feeding at a rate 40 times its Eddington limit (Eddington luminosity), seen just 1.5 billion years after the Big Bang. This exceptional observation has provided new insights into black hole growth from initial ‘seeds’ and challenges current theories with its rapid accretion rate and powerful outflows.) (ScitechDaily, Defying Physics: Supermassive Black Hole Devours 40x Faster Than Expected)

"Eddington mass limit, theoretical upper limit to the mass of a star or an accretion disk. The limit is named for English astrophysicist Sir Arthur Eddington. At the Eddington mass limit, the outward pressure of the star’s radiation balances the inward gravitational force. If a star exceeds this limit, its luminosity would be so high that it would blow off the outer layers of the star. The limit depends upon the specific internal conditions of the star and is around several hundred solar masses. The star with the largest mass determined to date is R136a1, a giant of about 265 solar masses that had as much as 320 solar masses when it was formed. The Eddington mass limit explains why stars much larger than this have not been observed. In the case of an accretion disk, the outward pressure of the disk’s radiation balances the inward flow of accretion." (Britannica, Eddington mass limit)

The mystery of dark energy can get light when X- and gamma-ray telescopes combine their abilities with the JWST telescope. The JWST can search extremely distant objects with new accuracy. The JWST and other telescopes see a black hole that devours 40 times faster than it should. That distant object tells something about the universe 1,5 billion years away from the Big Bang. That thing could tell that this black hole pulls lots of dark matter inside its event horizon. 

In theories of the beginning of time and space, dark matter, dark energy, visible material, and visible energy were together. They formed entirety with time. And it's possible that in the black holes. Those things can return together. 

The supermassive black holes can form when the entire galactic nebula falls. Or they form when massive stars collapse in a supernova explosion. Theoretically, any object can turn into a black hole if something pushes its radius inside the Scwarzschild radius. That radius is unique for all masses. Also, dark matter nebulas can form black holes. The observation that all galaxies don't involve dark matter tells us that also dark matter can form black holes. 

That distant active black hole tells something about material and energy density in the young universe. The interesting thing is that. Black holes should also eat dark matter and dark energy. Those distant black holes tell about a time when the energy level in the universe was higher. 


And there was also dark matter, and dark energy had a denser form. That active black hole in the early universe tells us. That there was more material and energy than expected. The active black holes pulled the material disks around them. The material- and star formation began. That supports the model that black holes formed before stars. And they caused whirls that made the Schwinger effect possible. The quarks were first. And then they formed protons and neutrons. 

When we talk about dark energy, there is a theory that dark energy forms when high-energy fields impact quarks or protons and neutrons. There are three quarks in proton and neutron. There is also other elementary particles in the proton. When energy pike travels through those particles. It affects their spin. The particle involves a whisks-looking structure that interacts with an energy field. And that structure sends the waves into energy fields like Higgs field. And we see those waves as dark energy the wave movement. That rips the universe into pieces. 

The idea is that gravity affects dark matter and dark energy as well it affects the visible energy and visible material. The black hole is like a tensor that connects dark matter and dark energy with visible material and visible energy. The focus is on the dark matter and dark energy effect on black hole interactions. Like the visible material. And visible energy affects black holes. 

When black holes pull material and energy inside them. Those things make them send radiation and gravitational waves. If we think that in the young universe, the material was denser. There are two models of the origin of dark matter. One is that the Big Bang released visible and dark matter. And another is that dark matter existed before the Big Bang. But if the last model is true that explains many things. But anyway, dark matter density in the young universe was higher. 

That means the black hole in the young universe pulls more dark matter inside it than the black hole in the modern universe. If there is lots of dark matter around the universe, that can tell that the Big Bang did not release dark matter. In that model, matter existed before the universe. 

But in other models, dark matter is released at some stage of the Big Bang. Sometimes is introduced that the dark matter follows and goes before the bubble or layer where most visible galaxies exist. 

Today researchers find dark energy and dark matter from rocks. The idea is that when a black hole pulls a dark matter nebula inside it it can form an energy burst that can seen from ancient stones. The system must compare information on the black holes and their position to the visible nebulas.

There could be axion clouds around neutron stars.

"An axion cloud around a neutron star. While some axions escape the star’s gravitational pull, many remain bound to the star and over a long period of time form a cloud surrounding it. The interaction with the neutron star’s strong magnetic field causes some axions to convert into photons – light that we can eventually detect with our telescopes on Earth. Credit: University of Amsterdam" (Physics.org, Physicists show that neutron stars may be shrouded in clouds of axions)

The neutron stars can be the key to the axions. Those still hypothetical,  mysterious dark matter particles should shroud neutron stars. They should also trapped in the neutron star's structure. The idea is that the heavy gravitation in neutron stars can pull axion particles near them. That allows researchers to observe hypothetical axion clouds' interaction with neutron stars' gravity and other energy fields. 

The hypothetical axions or dark matter particles can interact with gravity. Because all galaxies have no dark matter, that causes models that the dark matter can form similar structures as visible material. There are theorems that axions are similar to virtual, or quasiparticles as excitons. The idea is that the quarks or maybe some bosons can form similar holes as electrons.  In exciton electron jumps out from its orbital and starts to orbit its hole. So could things like quarks have that kind of effect? 

Radiation near neutron stars is very strong. That means there are electromagnetic shadows on the other side of the particles. Those electromagnetic shadows can act like material. And it's possible. That some electrons or some other particles start to orbit those shadows. 

And that is the only confirmed interaction between dark and visible material. In some simulations those particles send reflection. But that reflection is too weak to observe. There are theories that axions are particles that the wave-particle duality formed from gravitational waves. Or maybe axions are particles that spin very fast. In some models, axions are stretched to the needle-looking particles. 

The fast rotation or spin makes the electromagnetic field travel past the quantum field around the axion. That means the axion can act like a stealth bomber and aim the radion over it without reflection. Or in the alternative model, the axion is like a drill or screw that rolls the quantum field. Then that quantum field can travel out from the axion at the point of the spin axle. That forms the energy pike that is hard to notice. Because its diameter is too small.

Reseachers map dark universe: Euclid mission.



"The huge mosaic released by ESA’s Euclid space telescope on October 15, 2024, accounts for 1% of the wide survey that Euclid will capture over six years. The location and actual size of the mosaic on the Southern Sky is shown in yellow.

ESA's Euclid mission purpose is to find out the form of dark matter. The interesting question is this: are weakly interacting massive particles, or WIMPs, so-called real or virtual material? The virtual version means that there are so-called holes or electron-hole-type structures in the base energy field in the universe. 

That means the dark matter could be an exciton-type quasiparticle structure. In excitons, the electron jumps out from its orbital. And then that electron starts to orbit its own hole. The thing is that the depth of that electron hole determines how many electrons that hole can tie around it. 

That hole is at a lower energy level than the base energy level in the universe. Or in the most exciting version, those mysterious WIMPs, or part of them are so-called low-mass primordial black holes. If the WIMP is a so-called virtual particle.

It's possible. That the dark flow out from the universe forms that effect. The energy level in the universe is higher than around it. So, energy flows to the universe's environment. That flow can form the quantum shadow on the side, where the flow goes. That shadow or lower energy area pulls particles to them, and that thing creates the dark gravity effect, that we know as dark matter. 

Dark matter means gravity interaction, whose origin is unknown. The key question is this: what puts gravity waves move in the Higgs, or base energy field in the universe? Gravity is possible without mass. In those models, things like oscillating or shaking superstrings cause gravity waves. That we know as dark matter. 

One interesting thing about dark matter is that there is no dark matter in every galaxy. The one galaxy without dark matter doesn't make the dark matter nonexistent. That observation makes this effect more interesting than nobody expected. If dark matter is a so-called quasiparticle that observation means that it also quasiparticles can form similar structures as the so-called real material.

Dark energy is one of the biggest mysteries in the universe.

 Dark energy is one of the biggest mysteries in the universe. 


Dark energy is roughly 68% of the universe. The source of dark energy is unknown. Some researchers believe that black holes are the source of that unknown wave movement that rips the universe into pieces. The idea of this theory is that the universe is full of black holes. Some of them are smaller than atoms. Every black hole is the tube or tunnel between the third and fourth dimensions. 

The dark energy would be energy, that falls from the fourth dimension into the third dimension (or dimension where we live) through black holes. When material falls in a black hole, it interacts with energy that falls from the fourth dimension or the energy level that is so high, that material cannot interact with so high-energy material. 



Black holes can cause a situation where the energy level in a material rises so high that it loses its ability to interact with other particles. If we look at image 2, the droplet that is separated from the statue is the dimension or material whose energy level is so high that it cannot interact with other materials. For making the interaction between that bubble that symbolizes the fourth dimension and the 3D material the material must form the statue that connects the 4D energy level and 3D energy levels.

If we want to model the supernova explosion as a 2D layer we can use water and droplets that hit water the model how energy interacts in black holes. The reason why it's so difficult to model black holes and supernovas is simple. We cannot model a pothole that is a ball and hovers in the air. 

The supernova explosion is like a stone or droplet that impacts water. When that stone hits water it makes a pothole in it. Then water fills that pothole impacts the point of that pothole and forms a statue. Energy- and quantum fields interact in the same way. When a supernova explosion happens it pushes quantum fields away.  


Then the quantum fields fall into that pothole they are forming energy statues or energy pillars. If the energy pillar's energy level is high enough it forms the channel to the fourth dimension. So the energy that falls from the fourth dimension to the third dimension keeps that channel open or energy statue in its form. 

The fourth dimension is the energy level. And that means when the energy level of the material rises high enough, that thing forms a situation where particles are rising out from the third dimension. That thing forms a hole in dimension. 

The thing that makes black holes black is the extremely powerful gravitational field. But how black hole can send radiation and pull particles in it? The fact is that an extremely powerful gravitational field is the result of time dilation. The black hole travels in time. The energy statue that is so high that its top cannot interact with 3D material travels back in time. That means there is a hole in the dimension. Time travels backward in a black hole because its escaping velocity is higher than the speed of light.

Gravitational models that could revolutionize physics.

  Gravitational models that could revolutionize physics. 


There is a theory that gravitation interacts with dark matter by using the non-local model. That means the gravitation interaction happens through dark matter. The dark matter or especially "cold dark matter" forms the area there energy level is lower than outside it. 

And then quantum fields start to travel to that area. So gravitation is where quantum fields flow to the gravitational center. We can say that quantum fields are like rivers or whirls in water. And when they travel to the gravitational center they take particles with them. 


Theoretically, there are three types of material.


Hot dark matter

Visible material

Cold dark matter. 



The energy level of cold dark matter is lower than visible matter. Hot dark matter has an energy level higher than visible matter. In that model, the place of visible matter is between hot and cold dark matter. The cold dark matter is like "quantum ice". 

That means energy travels from visible matter to cold dark matter. Because cold dark matter is receiving part in that interaction, it is invisible to us. In energy models, energy travels from one particle to another until those particles reach the energy minimum. That term means that both particles reach the same energy level. The reason why visible matter and cold dark matter cannot reach energy minimum is that there is much more cold dark matter than visible matter. And that makes energy minimum impossible to get. 



The image above shows how plasma pulse forms. In that image, there is a black hole. But all plasma pulses are forming in the same way. The magnetic poles of the object pull anions and ions to them. And then behind that object, the electromagnetic forces, along with the gravitational field pull those particles together. 

The hot dark matter could be invisible for the same reason. The high energy, small-size particle pushes quantum strings past it. And then behind that particle those superstrings impact and that impact forms wave movement with extremely short wavelength. So that thing could be the source of dark energy. Or it could be one possible source of dark energy. 

Energy or wave movement flows to the cold dark matter, which could be material that formed after visible material. Hot dark matter would be material that formed before visible material. In that model, high-energy hot dark matter travels before the visible material. 

And now everybody asks "Why can't we not see hot dark matter"? The hot dark matter could be so high energy that it simply pushes radiation past it. The model is like in the plasma pulse. The radiation that hits the hot dark matter cannot reach that material because hot dark matter's energy level is too high and it pushes radiation past it. And if the radiation or superstrings will turn return together behind that particle that could explain dark energy. 

When those superstrings or extremely thin energy waves hit together back in the particle they form impact radiation with a very small wavelength. That thing could explain the dark energy. Or impacting superstrings can explain at least a small part of dark energy.

Is dark energy real- or a virtual phenomenon?

 

 


In this text, the term "virtual effect" is the same thing as "illusion". When we are thinking the dark energy there is the possibility that it's an illusion or virtual effect. The source of that effect can be in fast rotating structures like neutron stars, black holes. Or it can form in giant structures like in galaxies. Or the source of dark energy can be dark matter. The theory of dark matter does like this: the galaxy is the formation of the visible material that is part of a larger entirety. 

The reason that makes researchers believe that thing is simple. The center of galaxies rotates at the same speed as their edges. Or there are galaxies where is no dark matter. And that means the dark matter forms structures like visible material. So the galaxies whose center is rotating with the same speed with their edge are hovering at the cushion of dark matter that is far larger than the visible galaxy. 

Dark energy can be the wave movement whose origin is in dark matter. Dark matter is the mysterious gravitation effect that makes the edge of galaxies rotate at the same speed as the galaxy center. That means that galaxies are part of something far bigger entirety. 




Dark matter is not dark energy. But it might be some kind of source for that mysterious wave movement. The thing is that there is nothing mysterious in dark energy except its wave movement outside the observable electromagnetic spectrum. So the source of that wave movement can be the different size of particles than the visible material. 

But there is the possibility that dark energy is a so-called virtual phenomenon. That means its source can be at the edge of the rotating galaxies and transition disks of black holes. The cosmic hum that Voyager 1 probe found recently is giving a hint that the dark energy might have multiple frequencies. And some of them might be radio waves that cannot penetrate the plasma ball of the sun. So some parts of the dark energy can be the radio waves that we cannot observe from the ground. 

The fast-rotating neutron stars are also a thing that might help to find out the form of dark energy. When a neutron star rotates it sends wave movement through the space. And maybe that wave movement can interact with dark energy particles that might exist. 



The film above: Aluminum bullet impact 02




Image 2. 


Are mysterious tachyons the source of dark energy? 

Above this part of the text is a film where the aluminum bullet hits the layer. The same way the hypothetical tachyon particle is acting. If it will come to our third dimension. The tachyon will send the wave movement around it. Then it forms the virtual particle. And that effect forms the dark energy. In the second animation is the predicted interaction of the tachyon. 

When the particle that travels faster than the speed of light impacts the "light wall" it sends the virtual particle to a speed that is lower than the speed of light. Tachyon itself cannot come to our third dimension or decrease its speed to lower than the speed of light. 

When the tachyon hits the "light wall". That light wall pumps more energy to it. And that energy impulse sends the tachyon back to its tachyonic dimension. 

Could that thing explain why we cannot see either axion? Axion is another hypothetical particle that is suspected of forming dark matter. 

The idea is that there is the possibility that axion is the virtual particle. A small bubble in a dimension that exists extremely short time. During that time it can send the wave movement called dark energy. But can that thing have the gravitational effect? 

One of the wildest theories determines hypothetical tachyons as the source of dark energy. In the same way, some other theories determine the same way, hypothetical axions as the source of dark energy. 

The idea is that tachyons are hypothetical faster-than-light particles. Sometimes those particles can come to visit in the third dimension. When those tachyons are impacting the third dimension or "brane" if we are talking about the dimension by using the terms of the Brane theory. 

The idea is when the tachyon is impacting the dimension it forms the elongate virtual particle. That virtual particle is the quantum field that is forming in our third dimension. Because the tachyon is bringing energy to that power field, it sends the energy impulse. 

Then the quantum field of our dimension pushes the tachyon back to its dimension by transmitting energy to it. And that forms the small quantum vacuum where the quantum fields are impacting each other. That thing can send dark energy or wave movement that cannot be seen. By using regular instruments.

Does the dark matter has a particle form at all?



Dark matter means the mystery gravitational effect. The thing that forms this effect can be the material. Which elementary particles have a different size than the elementary particles of visible material have. 

That thing means that the wave movement that those particles are sending has the wavelength that makes it invisible. Another version of dark matter is that thing has no particle form at all. That means dark matter is the wave movement called dark energy. 

Image 2 is the neutron. The gluons jump between quarks. Neutron is formed of two down quarks and one up quarks and gluons. The image could portray a proton. Because it has a similar internal structure with a neutron. But the proton is formed by one down quark and two up quarks and gluons. 

The wavelength that those quantum tornadoes or rotating quantum channels are sending. Would be different than other particles sending. That thing makes the wave movement invisible. And maybe axions are hiding in those quantum tunnels. There is the possibility that there is a quantum vacuum in those tunnels. And that means outcoming energy pushes those quarks to one entirety. 



Image 2: https://en.wikipedia.org/wiki/Neutron


The mass of hypothetical axion-particles could tell the form of the dark matter. The thing is that the cosmology is that the dark energy is one of the mysteries that can solve another mystery. The mysteries of the dark universe is the thing that can solve where the material came from. 

The name axion of that theoretical particle is coming to an idea that the form of that thing could be elongated. Theories are telling that material is formed in wave-particle duality. That was caused by the mysterious event called  Big Bang. The question about the Big Bang is interesting. Was that thing released only energy that impacted with wave movement that already exists? And that impact caused the wave-particle duality that formed the visible universe. 

The thing is that dark matter is the mysterious gravitational effect. That means that there is the possibility that dark matter has not necessarily have a particular form. The dark energy or a dark wave movement that affects some extremely small particles can cause mysterious gravitational effects. That wave movement can affect the gluons and make them heavier or put them to a higher energy level than they should. 


The form of Dark matter is interesting. And maybe quite soon the researchers can answer two questions.


1) Is dark matter similar material with the visible material? That means the dark matter could turn to wave movement and otherwise. But if dark energy is the same thing as dark matter. That means the dark energy could create the gravitational effect. 

So that means the dark matter would not necessarily have the particle form. The dark wave movement that affects the gluons or some superstrings could cause the mysterious gravitational effect called "dark matter". 

2) And can the dark matter form atoms or molecules? Like visible material? The galaxies where is no dark matter is an interesting detail. 

That tells that dark matter can form the structures like visible material. But are those dark matter structures some kind of clouds of nebulas formed of dark matter? Or is there some kind of more complicated structures that are formed of dark matter? 


The weakness in the Big Bang theory is that it doesn't answer where the thing that exploded came from? 


The Big Bang theory is always the solution for the origin of the material. But where did the material or wave movement  Big Bang released come from? The moment of the Big Bang is point zero in the universe's history. But what happened in the point minus one (-1)? 

There was something that released the material to the universe. Or is it so? If we think that dark matter is the dominating form of material. There is a possibility that the crossing wave movement turned the dark matter into visible material. 

So if the dark matter is similar material with the visible material. The answer for the Big Bang can cause because of the wave-particle duality. But getting acceptance of this theory dark matter should have a similar particle form with the visible material. 

There is the possibility that the wave-particle duality forms when the quantum fields of the particles will touch each other. That thing can cause quantum friction or quantum spark. That thing will turn the quantum field or the superstring that forms that quantum field turns to a roll or yarn ball-shaped structure.

Is dark matter the result of imperfect annihilation?

 

 

 


Dark matter is a mystery. There are some suspected impacts with material and dark matter in particle accelerators. But otherwise, that thing is a mystery. Dark matter could be the source of dark energy. 

There is the possibility. That dark energy is similar to neutron radiation. When radiation hits dark matter. It would release extra energy in the form of radiation or wave movement. 

Dark matter is the gravitational effect. That dominates the universe. There is the possibility that the imperfect annihilation caused the part of the material to turn to the thing that we are calling visible material. There is about 15% of material in the universe. That is visible to us. Last of it is the mysterious thing that interacts only by gravitation with visible material. 

But when we are thinking about its form there is one thing that might explain why dark matter is not visible. If we think about the string theory the material is like a yarn ball. And annihilation reaction is the case where the strings of those yarn balls are opening. 

The string theory describes the material as the ball that is formed of wave movement. There is the possibility that if the energy level of the impacting particles is not the same the annihilation would not be perfect. 

So could the dark matter be the result of the imperfect annihilation? That means that material turns to energy when a particle and its anti-particle pair will impact. The case where two particles are turning to energy is true when the particles have the same mass. 

But if the other yarn ball is bigger the annihilation is imperfect. The case is that if the energy level of the participants of annihilation is not symmetrical. And another participant is higher energetic than others the annihilation would not turn the entire material into energy. 

When the material is turning to energy in the material-antimatter impact means the impact of particles releases only the same number of strings as the lighter particle has. If we think of those particles as the yarn balls. The particle is at a higher energy level than the other is a bigger yarn ball. 

The idea is that when a particle hits its mirror particle it can turn only its mass of material to energy. So if the electron and positron are impacting and the energy level of the other participant of the annihilation is higher. That causes that there are remainings of the higher energetic particle. 

So, at the beginning of the universe. There was the Big Bang. The event, that released all material and energy to the universe. Or there is a theory that at the first released wave movement. Then that wave movement turned to particle-antiparticle pairs. And after that happened the big annihilation that formed the elementary particles. 

But if we are thinking about the Big Bang. And particle wave-movement duality we are facing one interesting thing. When crossing wave movements form material. They are forming the antimatter-material pairs. So that thing means that there is the possibility that the energy levels of those particle pairs were different. 

And that means the annihilation between them would be imperfect. So if we think like that. There is the possibility that the asymmetry in annihilation caused the visible material and dark matter to form. 

The energy asymmetry causes an effect. The particles of dark matter and visible material are not the same sizes. So we cannot see the radiation that comes from the dark matter. So could that radiation be dark energy? There is the possibility that dark energy is similar to neutron radiation. That thing would form. 

When the particles of dark matter will stress with radiation. And after energy stress, those invisible particles will release their extra energy as a radiation burst. The fact is that dark matter is dominating. And should we ask like this? Is the visible material result of imperfect annihilation?

Where is "Planet 9"?

 Where is "Planet 9"?


Planet Neptune


The mystery of Planet X or Planet 9 is an interesting thing. There is something that causes errors in the trajectory of planet Neptune. And that thing is predicted to be an unknown planet. The thing that makes this planet so mysterious is that it hasn't been detected yet. 

There is the possibility that the temperature of the surface of that planet is about 3 Kelvin which means it hides in the cosmic background. But as you see that mysterious planet is theory. 

There is also another explanation about the error of the trajectory of planet Neptune. That theory goes like this: a gravitational effect of Alpha Centauri, Proxima Centauri, and Luhman-16 systems is causing that error. But that gravitational effect should affect also Oort clouds. Sometimes the group of small asteroids at the Kuiper Belt has explained the source of the mysterious errors in the trajectory of Neptune. 

So what causes those famous. And also unknown errors to the trajectory of Neptune? Is it some kind of energy burst? And does that thing have some kind of connection with Neptune's "Dark spots"? 

The thing is that that the source of the mysterious gravitational effect is unknown. Researchers are offered The grapefruit-size black hole and dark matter clouds for the thing that is causing the error in the trajectory of Neptune. The problem with those explanations is. That this kind of gravitational effect should cause the atmosphere of that planet. 

Sometimes there is suspicion that the wormhole is causing the energy effect that causes the mysterious error in trajectory. When the object is near zero kelvin degrees the methane can close the helium in it like minerals are closing water in them. 

When the wormhole travels through the object it will expand helium and destroy the crystals that are closing the helium in them. The energy of the wormhole would start to boil helium. And that starts the mysterious geyser burst at extremely low pressure and gravitation. But nobody has proven the existence of wormholes yet.

The thing is that planet 9 is sometimes searched very intensively. And the last time was when astronomers found the planet Proxima B near Proxima Centauri. There is made billions of profiles about that mysterious effect. "Planet 9" is predicted to be a very old rocky planet where is no volcanic activity. That means it could be the rogue planet formed somewhere else in the universe. Maybe the nova or supernova explosion has pushed that object away from its star. But the only thing that is confirmed is the mysterious gravitational effect in the trajectory of Neptune.

Dark matter and its relationship to parallel universe theory.






Image 1



Is parallel universe or multiverse theory science or science fiction? The answer is that theories are theories until they can be proven true or false. That's why we might say that multiverse is only a theory. 


But if a multiverse exists we can explain dark energy by using the multiverse theory as the base. And simply saying that outside gravitational effect from other universes causes the expansion of the universe. So the fact is that if the other universes exist they are there can we see them or not. The ability to observe the thing doesn't affect its existence. 

The thing that makes the dark matter so interesting is that is invisible to us. It's similar material with other materials. But we just cannot see it. 


There is no evidence about the existence of other universes. There was one big thing or hype that NASA has found the mirror universe. 

But that thing was a so-called false alarm. The article that caused that alarm was the highlight that "NASA has found new universe". But the original article told about exoplanets. 

The existence of other universes would explain why we cannot see dark energy or dark matter. The radiation and gravitation source outside the universe could explain dark matter and dark energy. But there is no observation about other universes. 


Theory about mirror-universe. 


So sometimes is introduced an interesting hypothesis that dark matter is the superposition of the visible material. The thing is that the dark matter would be opposite to the visible material. The origin of that idea is in the hypothesis. 

That during the Big Bang, the fast-spinning black hole formed two bubbles of material. Or rather saying send two rays of radiation to the opposite directions. And both of those wave movement rays would turn to the universe. 

That means the material would be the superposition. If the material is a superposition that would explain why we cannot see the dark matter. The thing that makes the superposition is the radiation that comes behind the dominating particle. The term means that the oscillation of the dominating particle would copy to the recessive particle. 

And when the wave movement travels through the universe the power of that radiation would get lower. That means the superpositioned particles would be a little bit different in size. Maybe that thing is meanless if the distance of superposition is a couple of hundred meters. But when the distance of those particles is about billions of light-years that thing has a mean. 

What if dark matter doesn't exist? The thing that can explain the expansion of the universe is the outcoming gravitational effect. So what if dark matter does not exist? Does that close the dark energy away? 

Dark energy is not connected to dark matter. That means the dark matter is the wave movement which origin is unknown. Sometimes the empty bubbles of the universe are introduced as the source of dark energy. The origin of those bubbles is interesting because something has been pulling material away from those areas. The reason for that is the introduced black holes. But there seems to be not that kind of object. 

So could the reason why those mysterious bubbles are formed the vaporized black hole. Or is it some mysterious radiation that has pushed material away from those bubbles? Sometimes even the anti gravitation has been introduced as the reason why those bubbles formed. 

And in the wildest theories, there are new universes formed in those bubbles. In some versions of those theories, our universe is also a bubble in the far bigger universe. If the material of our universe has different size particles than other universes we cannot see that other universe. 



Image 2: The relations of the parts of the universe. And as you see the most dominating effect is dark energy. The part of visible material is only a couple of percent. That's why we should not call visible material "regular material". There are unconfirmed theories that also dark matter can form dark or invisible atoms.

But those theories are just theories. The confirmation of those theories requires that the researchers would know dark matter better. And the fact is that the only observation of dark matter is the gravitational interaction. So there is needed much more research to confirm that theory. 


How do empty bubbles form dark energy?


When some particles like neutrinos or gluons are released near the empty bubble their speed can cross the speed of light in the regular universe. There is no medium in those empty bubbles. That means the speed of photons and other particles is higher in those bubbles. And when those particles hit the medium they release their extra energy as radiation. 

The thing that can prove that dark matter does not exist is the existence of other universes. If the parallel universes are true, that means the outcoming gravitational effect will expand our universe. 

The thing is that these kinds of theories are interesting.  And there is one thing that can break the hypothesis of dark matter. But otherwise, if the dark matter forms similar structures with visible material. The question is: why cannot form invisible universes? 

There is one thing that can erase the dark matter.  That thing is the parallel universe theory. If there is another universe or bubbles of material the gravitational effect of those bubbles can explain the universe's expansion. 

But the thing is that those hypothetical other universes might hide behind giant clouds of dust and matter. They might be so dim that the light of our universe and its objects are covering their existence. But there is another explanation. And that is that those hypothetical other universes are formed of dark matter. 

What if those parallel universes are formed of a material. Which particles are a different size than particles in our universe? That means they are formed of dark matter.

Could there be invisible galaxies in the universe?



The thing is that if there is a chemically similar galaxy with Milky Way far away from us. There is the possibility that the radiation of the Milky Way pushes the radiation away from the Milky Way. That thing means that if the Milky Way pushes the radiation away. That thing makes it impossible to see some objects. 

Could the dark matter be some kind of condition of the material that the electromagnetic radiation would travel across it without causing the reflection? If we are thinking of the situation that is in the image above this text. There is the possibility that some galaxies have a certain form of a halo that pushes the electromagnetic radiation traveling around that galaxy away from it. 

So that kind of case where the electromagnetic radiation would travel around the object would be similar to what makes things like stealth bombers invisible for radars. The scale of the galaxy is much bigger than some stealth bombers. But there is the possibility that some kind of quantum phenomenon can make the entire galaxies impossible to see at least from great distances. 

Some another version of this question about invisible galaxies. Is that somewhere between Earth and that galaxy is the scattering field. That denies the wave movement to travel through that area. 


The ghost material and quantum stealth


Theoretically is possible to make the material that turns to the quantum cloud and returns to its form. That means theoretically at least the non-organic creature like a screw or car can turn to a quantum cloud. And when the time is coming that quantum cloud can return to its original form. So if research makes this thing into practice. That allows turning the aircraft to the ghost that could travel through the walls. 

There is the possibility that some types of material have the ability that electromagnetic radiation would travel through it and pass the atoms. If that thing is possible to make that allows to make the invisible materials. But there is one thing that we might forget. Theoretically is possible to make the ghost by using quantum technology. 

The idea is that the distance of the particles that are forming the nucleus of the atoms is pushed to a long distance of each other. If quarks that are forming the structure would be connected with the superstrings. That thing makes it possible to turn the physical object into a quantum cloud. And if those strings are true. Decreasing the energy pumping will make those particles return to form.

The dark matter and the "Big Bang" theory (What was before the Big Bang?)




Kimmo Huosionmaa

The parallel universe theory could be only the academical "joke" without one thing, what astronomers have found. They have discovered the thing, that there is too much matter in the universe and this dark matter, what would not send any kind of radiation makes one thing happen. There is also found the thing, called "dark energy" in the universe, and that means that the dark matter exists. There were actually found also the "dark energy, and this was sometimes explained that at the beginning of the history, just in the time of "Big Bang" was too much energy in the universe.


The "dark energy" is actually the gravitation, what caused by this dark matter, what is actually mostly atomized hydrogen, or there is a theory, that the dark matter is something more exotic. But normally I have thought that this dark matter is hydrogen or some other things like protons, what means ionized hydrogen or electrons. If the dark matter would be electrons, that thing would be noticed as the radio signals, that comes from nowhere. And maybe the "three-kelvin radiation" is part of the dark matter.


But when we are thinking about the source of that matter, what we cannot see straight, but we can see the gravitation of this so-called "dark matter", because of all calculations, what is made for calculating the universe movements are sometimes very inaccurate, what means that something disturbs metering of the objects. And when we are thinking, where that matter is coming from, there is one explanation for that. This is that just after "Big bang" the universe were full of quasars and black holes, what just exploded. In the theory of the "Big Bang", the universe was actually the hypermassive black hole, what was started to send photons.


The origin of that black hole would be in the universe, what was existed before our own universe. This supermassive particle would involve all material, what was in that past universe, And it was in the middle of nowhere in the empty space, and if the supermassive particle  would not get anything in it, would that thing cause that the black hole starts to pull the material away as a "Hawking's radiation", and because the black hole would lose its mass the steaming if the black hole would go faster and faster. And suddenly it would explode.


Somebody like me has sometimes thought that maybe "Big Bang" was caused by the impact of two hypermassive black holes, and another of those particles were antimatter, wah caused the very huge explosion. Sometimes I have seen theories, about the "Big Bang" that this very rough phenomenon, what can actually be caused by the thing, that two interplanetary nebulas were impacted together, and if another one was antimatter cloud, would the released energy level be very huge.


 When we are thinking about that theory, the different electric charges would drive those clouds together, and the annihilation would cause the born of the universe. And because annihilation, what happens when antimatter and matter touch together and the origin of dark matter could be explained that at the beginning of the universe was too much energy, and that caused that there is a matter what was not calculated.

When those clouds of antimatter and matter touched together, the annihilation caused the very big explosion, and in this case, That phenomenon would be known as the "Big Bang"  But there is another theory about the existence of the dark matter. That is that there is another universe in somewhere, and the wormhole or singularity would transfer material between another universe and our universe. This theory is very often passed in the TV-programs, but if some matter comes from another universe, would it increase the mass in our universe.
