The cosmic microwave background, CMB, is one of the most important discoveries in astronomy's history.



But first to gravity waves. The gravity waves are quite similar to synchrotron radiation. We can think that there is always. Some kind of energy field in the universe that keeps the particles in their form. That field forms the counter pressure that presses the particle in its form. 

When a particle that might be a whisk-shaped structure starts to rotate that structure pushes the field around it away. We can see that thing as a gravitational wave. The effect is similar to the case where we rotate some dough whisk under water. That thing sends wave movement but it's so weak that we cannot see it. 

When that whisk starts to rotate faster and faster. It makes growing potholes or bubbles in water. In the same way, we can think that a particle is like a whisk. It must rotate fast enough that it can turn to look solid. The gravitational pothole is the thing that forms when the particle rotates very fast. 

The reason is that the energy field around it has no time to fill that hole. That means that the particle or gravity center will not make gravity. It just aims at the field in some direction. 

In that model There forms a bubble in the field around the particle's spin axle. That pulls the field to the spin axle. That pulls particles into that center. 


When that structure rotates fast enough it pushes the field away more often and because those structures are very small the field that travels to fill that hole cannot fill it perfectly. 


The cosmic microwave background, CMB tells something about the universe's expansion. There are holes, or colder areas in the CMB. Which means the universe doesn't expand commonly. There are areas. That moves faster than others.  We can think that the CMB is like dough that the edge of the universe stretches. If we stretch dough there are holes in there. That means the CMB tells something about the universe's expansion. 

If we think that the visible universe is some kind of ball- or maybe an egg, or maybe a donut or torus-shaped structure there are galaxies and material at its shell. That can cause an effect on there material form inside that visible shape comes also to that shell. And that means there is the possibility that some particles or radiation hits galaxies faster than researchers think. In some visions the dark matter or cold dark matter CDM is outside the visible universe. 

That thing pulls objects away with gravity. And if there is no mass center or that hypothetical mass center is too far that means the material in the outer shell of the universe pulls objects to the shell of that bubble. The holes in the cosmic plasma make energy and material fall into them, and that can form single-atom fusion. That thing is possible if those atom's speed is high enough. That can make it possible for dark energy or some part of it to form in cosmic voids where radiation impacts like in vacuum bombs. 

So, could the dark energy form when the particles travel to galaxies from the inner structure of the universe? And there is a possibility that there is lots of dark matter outside the visible universe. If there is a similar plasma shell that heliosphere forms outside our solar system that means there is some kind of plasma source. The impact waves can form only if there is some kind of counter waves. 

The origin of the CMB might be in the Big Bang. That energy field resists and turns all wave movements shorter. One of the explanations for dark energy is particles or other radiation that travel in CMB. When a particle or wave interacts with CMB that pushes wave in that field. That means the origin of dark energy can be in some kind of interaction with CMB and some other field like the Higgs field. 

The gravity waves are waves. That seems to affect the CMB. So if we can remove CMB from some point, that means the CMB from another place will fall into that point.

Cosmic web and dark interaction.

The magnetic shockwaves that illuminate the cosmic web don't form without reason. In that phenomenon, something pumps energy into the magnetic objects like neutron stars or magnetic fields.  That releases a very strong magnetic pulse to the cosmic web. An interesting question is: where does that energy come from? 

The cosmic web is the largest known structure in the universe. That web connects galaxies with each other. In some models, plasma flows are between stars and even between galaxies. The cosmic web is the material that accumulates around something. That something can be the chain of dark matter particles. 

Called weakly interacting massive particles, WIMPs. The WIMP is a mysterious thing in the universe. Sometimes researchers think that WIMP is some kind of quasiparticle or maybe a miniature black hole. Or maybe WIMP is a virtual particle, the energy shadow that forms on the opposite side of the particle. The energy or quantum shadow makes a situation where the energy tries to fill that shadow. 

And that means the WIMP could be some kind of energy field that acts like a particle. One of the explanations can be the standing gravitational waves. The only known thing is that. There is some kind of gravitational effect that the source is unknown. In those models, dark energy can be the energy that primordial or quantum-size black holes can send while they vaporize.

The accelerating expansion of the universe can have two reasons. 


1) The gravity turns weaker. 


2) Some kinds of small high-energy objects like primordial black holes can release energy stored in them. 


The model means that when quantum fields around particles turn weaker and material in the universe turns less dense that means the vaporization in things like black holes accelerates. That means. It's possible. That dark energy and Hawking radiation could be the same thing. 

But then we can look at the newest observations about dark matter and try to complete its models we can see that dark matter can form similar structures as visible material. So, dark matter can form things like black holes. Dark matter interacts with black holes through gravitation. 

When we try to explain things like the cosmic web we can see that there is some kind of gravitational effect that forms the web. There is something that forms that web. Nothing happens by itself in the universe. There is energy that makes things happen. While energy moves that cause actions. Every action requires energy. And standing energy doesn't do anything. Energy must move so that it can make something.

Things like power loss are the reason for the nature of wave movement. When an object sends energy to another object the energy sector expands. So a long-distance major part of the energy doesn't hit the object. Anyway, the ball-shaped particle sends wave movement into a ball-shaped form, and only a small part of the energy will impact the receiving particle. 

When we think about things like spin spinning particles like neutrons can collect wave movement into the middle of itself. Then it can turn that radiation into an energy beam. The idea is that. Extremely fast spinning particles can collect energy into it. And then that thing forms the energy pike that travels out from its axle.

The black holes and material do not form energy. They store energy in a new form. And when those objects energy levels turn high enough, the energy flow turns away from those objects. Sometimes gravity is explained using vaporizing ice as the model. When we put ice on the hot layer the ice starts to send vapor. During that process, the ice bounds energy and transfers it into vapor. And that decreases the temperature of the layer. 

The energy travels to that point from other places. And if that thing happens in the universe that energy is the quantum field that transports particles into that point. So in the universe layer is the Higgs field and the heat is the effect that pulls energy out from that field. 


Above: The Cosmic Microwave Background, CMB (Wikipedia, Cosmic microwave background). Does the dark energy background look like this? 

The dark matter is the mystery. There is a possibility that dark energy forms when WIMPs send wave movement. But today researchers know that dark matter and dark energy might not have cosmological constant. That means. The dark energy can form similar structures. As the cosmic microwave background. And we know that there are galaxies without dark matter. 

That means. Dark matter can create similar forms as visible matter. So there can be giant dark matter clouds in the universe. The stable environment can cause a situation where the energy strings can travel past the energy potholes like exciton. In that case, the energy string closes other energy impulses away. And that denies the weak outside field filling the pothole. 

So when we think about things like Einstein's Theory of Relativity and the MOND (Modified Newtonian Dynamics) we face one interesting question: can both of those models be right? Researchers tried to find the mistakes from Einstein's models and Einstein was right again. 

Sometimes difference between two models forms from the direction where we close that model. If we remember things like Newtonian gravitational models we can see that. They are suitable tools for certain scales. The scale and needed accuracy determine what theory, model, and formula we use.

Astronomers could have a model for why photons from GRB 221009A were at a high energy level.
