None of the black holes interacts alone.

“At the center of the Milky Way, something immense and invisible exerts a powerful gravitational grip. For decades, astronomers have assumed it was a supermassive black hole. But new research suggests a more unconventional possibility: a dense concentration of exotic dark matter that could unify the galaxy’s inner chaos and outer calm under a single framework.

None of the black holes interacts alone. This means that black holes are also part of their environment. And gravitation is not the only interaction with a black hole. 

Supermassive black hole in the center of our galaxy might not be a black hole. Or, otherwise, the supermassive black hole interaction with its environment is more complicated than anybody expected. The new study suggests that the main part of the supermassive object in the center of the Milky Way is composed of dark matter particles that are similar to fermions. Or maybe fermions like electrons are things that form the dark structure in the center of the Milky Way. 

Or, otherwise, we must realize that there is a black hole with dark matter particles orbiting. This means there is a black hole in the middle of the fast-orbiting electron or quark cloud. The spin of those particles would be awesome. So those particles would be more massive than particles outside that structure. And in that case reseachers must calculate what part of the gravitation formed the black hole, and what part of the gravitational effect is formed of those fermions or other dark matter particles. So, the center of the Milky Way is the combination of a black hole and particles that orbit this object. 

Another thing is that. Every other black hole has a dark matter halo. And a visible matter halo. In the case of a black hole, the key question is always this: which has the dominating effect: does the dominating effect come from the black hole or its halo? The only known fact is that none of the black holes interacts alone.  There is also a model of the center of the Milky Way. Involves structure. There is a group of black holes orbiting the supermassive gravity center. In some model. The massive pressure near the center of the Milky Way presses matter into a black hole, just before it falls into the middle of the Milky Way. 

The only thing that is sure. Is that. Dark matter and visible matter. Both can form a black hole.  If a black hole forms. In the dark matter bubble, or denser point of dark matter. That can cause a situation where the black hole turns more massive than it should. Gravitation is the only known interaction between dark and visible matter. 

“Some astronomers think the Milky Way’s center could be hiding something stranger than a supermassive black hole. In a new study, researchers argue that the object shaping the orbits of nearby stars might instead be an ultra-dense concentration of dark matter that creates nearly the same gravitational footprint as a black hole.” (ScitechDaily, The Center of Our Galaxy May Not Be a Black Hole)

“Their results, published in Monthly Notices of the Royal Astronomical Society (MNRAS), challenge the standard picture in which Sagittarius A* (Sgr A*) is a supermassive black hole that dominates the region’s gravity. The best-known evidence for that black hole interpretation comes from the S-stars, a group of stars that loop around the center at velocities reaching several thousand kilometers per second.” (ScitechDaily, The Center of Our Galaxy May Not Be a Black Hole)

"Instead of relying on a black hole, the international research team proposes a different explanation. They argue that a particular variety of dark matter composed of fermions, which are light subatomic particles, could organize itself into a distinctive structure consistent with observations of the Milky Way’s core.” (ScitechDaily, The Center of Our Galaxy May Not Be a Black Hole)

The energy level of those particles is very high. So those particles are more massive than particles outside the halo. And that means that. The black hole and its halo. Are both. Interact with their environment. So in larger-scale structures, the Milky Way. Just like other galaxies interact as an entirety. There are all stars, back holes, dust, and other things. Forming the massive gravitational entirety. The black hole interaction. It is much more complicated than just gravity that pulls objects inside it. 

The black hole halo. And its relativistic jet transports energy. Also in the opposite direction. We see that energy. As gamma- and x-rays. When a black hole sends energy to the galaxy’s outer halo. That energy puts a halo to shine. There is also the impact of radiation and particles that surround the galaxy. This impact point is similar to the heliopause. There are particles from the sun. That impacts the particle flows from other stars. Similar standing wave surrounds. galaxies, and when a relativistic jet impacts that structure, this structure sends energy into the center of that bubble or halo. This energy. It has a role in energy. 

And matter flows in the galaxy. That energy reflection pushes particles and other objects back to the galaxy’s center. And this is one of the reasons why there is a glowing bubble in the center of the galaxy. Mainly, that glow forms when the relativistic jet travels through that point. But in the same way. Energy that reflects from the galactic halo. Has a role in that thing.

Everything forms in spirals.

Above: The fractal structure of the Messier-74 galaxy. In those structures energy and gravity are in an eternal race. You can also see things like holes in that gas disk, or a galactic nebula.  If there is a whirl there are four possibilities. There can form planets and the sun. But if the star that forms is too big, it blows the material disk away from its environment. And that denies the planetary system formation. Or if the disk is very massive it falls straight to a black hole. The empty places in the disk are areas where some cosmic catastrophe has blown the material away. 

Or there is a possibility that a denser spherically-shaped material cloud or nebula pulls material away from the middle of it. Or in those holes formed stars and planets or black holes pulled that gas away from those holes in the nebula. Or, maybe the extremely powerful supernovas blew cosmic gas away from that point. 

JWST found new data to explain how spiral galaxies form. There are two structures in the spiral galaxy: thin and thick. The thin disk can form earlier and then the thin structure's gravity starts to collect the thick structure around it. Those two structures move at different speeds and that causes problems with the models. 

The spiral structures that move at different speeds create the whirls that start to collect material into them. So, the star formation begins in those points. That thing explains the star, planet, and finally neutron star and black hole formation as the whirls that form around material. Or actually, all particles in the universe from the quark to the most massive objects form from whirls.

"Webb/NIRCam composite images of a quarter of the team’s sample sorted by increasing redshift. Image credit: Tsukui et al., doi: 10.1093/mnras/staf604." (SciNews, Webb Sheds New Light on Structural Evolution of Disk Galaxies)

If the whirl is large enough it can press the particle or any other object into one entirety called a singularity. The particle that spins at a very high speed binds quantum fields around itself. And how big an object can that process form? That depends on the energy level of that particle. The energy transfer into that particle continues until it can push that whirl away from it. So theoretically one single particle like a proton or electron can form a supermassive black hole. But that requires an absolutely stable environment. 

The requirement is that the particles can form such a large whirl and bind energy or quantum fields into it so fast that it cannot push that energy away. That means the particle must spin with an extremely high speed. The idea is that the black hole or any other structure in the universe creates a whirl around it. An interesting thing is that all objects from stars to planets are forming from whirl-shaped structures. The spiral galaxy is actually the supermassive black hole’s material disk. That disk keeps the supermassive black hole in its form. Without that disk, the energy that is trapped in the black hole will be released. 

The black hole’s relativistic jet tells that the gravity center is a structure that aims, or conducts energy somewhere else. Energy travels to the black hole’s spin axis and there forms the relativistic jets. The main problem is: is the source of the relativistic jet outside the event horizon or inside it? In a wormhole model, the black hole forms a gravitational tornado. The structure forms a situation where a gravitational field or quantum field forms a tornado-shaped structure. The idea of that phenomenon is that if the gravity field turns into a spiral, then that thing causes a situation where there is no gravity field in the black hole’s spin axis. Maybe that channel explains the relativistic jet.

Galaxies from the dawn of the universe tell how material is formed in the universe.

"Six images of galaxies taken from nearly 800,000, from upper left to lower right: the present-day universe, and 3, 4, 8, 9, and 10 billion years ago. Credit: M. Franco / C. Casey / COSMOS-Web collaboration" (ScitechDaily, When the Universe Broke the Rules: Webb Spots “Impossible” Galaxies at Cosmic Dawn)

Before stars start to form there must be some gravity center. Then that gravity center started to pull hydrogen or hydrogen ions into that point. The reionization where cosmic radiation pushes electrons out from an atom's orbitals is an interesting thing. There must be some kind of source for that radiation. And in some models the Big Bang caused shine. That caused reflection from those atoms causing that reionization. 

There is a possibility that in the young universe’s quantum field formed some kind of turbulence or whirls that pulled hydrogen ions against each other. There must be a lot of material that the fusion starts in those hydrogen stars. When we say that those first stars burn hydrogen to helium we forget one thing. In the fusion tests. Systems deuterium and tritium. Those heavy isotopes of hydrogen consist of one proton and one neutron (deuterium), or one proton and two neutrons (tritium). In Helium 3 is one neutron and two protons. So, which formed first, deuterium, tritium or Helium 3?

The “impossible” galaxies from the young universe give a view to material advance. Those very early galaxies give data about the theorem that dark matter can form visible material or even wobble between visible material and dark matter states. Those young galaxies tell about the interaction between dark and visible material. And they can offer an answer to the question, can the weakly interacting massive particle, WIMP be some “real” particle, or can it be a whirl in some quantum field? And that means the dark matter could be some kind of turbulence in some quantum field. 

"Researchers propose that early elliptical galaxies may be responsible for a significant portion of the cosmic microwave background, potentially undermining the Big Bang’s most trusted evidence. (Artist’s concept.) Credit: SciTechDaily.com" (ScitechDaily, Rewriting Cosmology: New Calculations Shake Foundations of the Big Bang Theory)

But everything is open until astronomers and physicists find the first sign of the mysterious WIMP. Dark matter is one of the biggest mysteries in the universe. It's a gravity effect without any source. In new models, it is possible that the gravity field can form the turbulence or whirl in that field. And if the whirl in the gravity field increases its power. Theoretically, packed gravitational fields can form even a black hole. In that case, the gravity waves that impact each other form a situation where the gravity pothole turns deeper and deeper Until even light cannot escape from there. 

And that closes the past universe partially away from theory where a detonated black hole formed the universe. There is a possibility that the black hole or Kugelblitz black hole formed straight from energy fields interaction and then that detonated black hole formed the event called the Big Bang. And then again, where did those gravity waves come from?

But we know that dark matter has a role in the galaxies. If dark matter doesn’t act as glue that means galaxies must rotate slower and stars should be closer to each other so that the structure stays in its form. Some galaxies have no dark matter. And some of them have. And that means dark matter is similar to visible material because it can form structures. But the dark matter form is a mystery. There is a possibility that WIMPs are like quasiparticles. One suggestion is that WIMP is like an exciton. 

In an exciton, the electron starts to orbit its own hole. So if that electron hole turns deep enough it could pull all reflection from the particle that orbits it into that hole. It is theoretically possible that the dark matter particle or WIMP is the miniature black hole that some other particle orbits. In some models, it is possible that one of three quarks can jump out from baryons. That leaves holes in the baryon structure and that can cause an effect where that baryon starts to wave or wobble. But those models are purely theoretical.

Can dark matter annihilate in the middle of the Milky Way?

"Strange signals from the Milky Way’s core suggest dark matter is annihilating itself in a cosmic collision. Scientists believe these energy bursts could be the missing clue in the search for one of the universe’s greatest mysteries. Credit: SciTechDaily.com" (ScitechDaily, Dark Matter May Be Annihilating Itself at the Heart of the Milky Way)

"A strange energy source at the center of the Milky Way may be a new type of dark matter.

Scientists found that hydrogen gas there is ionized in an unexpected way, which cosmic rays can’t explain. Instead, they propose that lightweight dark matter particles are colliding and producing charged particles. This could reshape how we think about dark matter and its role in the universe." (ScitechDaily, Dark Matter May Be Annihilating Itself at the Heart of the Milky Way)

There are theories about weakly interacting massive particles, WIMPs, or axions. Those theoretical particles should form dark matter. If dark matter has a material form. The new model explains that the extremely high energy levels in the center of galaxies form when WIMPs or axons annihilate with each other. 

This model means that the hypothetical dark matter particles have their mirror particles. Those mirror particles annihilate with WIMP/axions. The particle-antiparticle pairs annihilate or turn into energy when they touch each other. So the antimatter annihilation in the dark matter can explain dark energy. There is the possibility that WIMPs and axions are different particles. 

There is a theory that dark matter forms two types of particles. 

1) Hot dark matter, or high energy dark matter. 

2) Cold dark matter, or low energy dark matter. 

In some models WIMP is simply a so-called quantum-size black hole. There is the possibility that the particle can turn into a singularity. And if energy flow travels over it that can cause a situation in which energy locks a black hole into energy pocket. And that energy pocket denies that black holes turn into energy. In that model those things put small energy strings to move. And that makes dark matter or unknown gravity effect and dark energy. 

It's possible. Hot dark matter particles are so small that we cannot see the radiation that they send. So the low-energy dark matter particles can have so soft form or their quantum field structure is not coherent. That means those particles can let wave movement go through them. Or those particles are so slight that quantum fields around them just rotate over them without any interaction. 

But then we can go to the interesting model of dimensions. The fourth dimension can explain hot dark matter and tachyons. When, a hypothetical tachyon particle travels with a speed, higher than the speed of light. 

That particle will not interact with other particles. When the interaction starts the tachyon loses its energy and turns into photons. 

Or the photon's ring-shaped structure gives a tip: maybe the photon is like the ring that forms when aircraft cross the speed of light. A similar ring forms when something releases its energy. And that "something" can be the tachyon that decreases its speed. 

It's possible. That the photon is the remnant of the shockwave that some other particle leaves behind it. When tachyon slows its speed it can transform into a photon, Higgs boson, or neutrino. So we must find the neutrino that comes from nowhere. And that makes sterile neutrinos important. Sterile neutrino means that the neutrino does not travel through space. 

Areas in the center of the galaxy. Are at a very high energy level. When we think that the dimension is like a room. The difference between energy levels must fit within certain limits. If the energy level difference between two particles is too high, they cannot exchange information. 

The roof is the energy level where the particle loses its ability to interact with other particles in the third dimension. So the center of the galaxy is like an energy tower. That top can interact with the tachyon. The energy hill or energy mountain can pull energy off the bottom of the tachyon. 

In this model, the low energy or cold dark matter can be particles that rise from the second dimension. That dimension is particles that have length and width but not height. When those low-energy level particles arrive at the center of the galaxy that high-energy area starts to push energy to them. 

The problem with 2D particles is that they can transmit energy from them to other 2D particles. So mainly energy travels out of the edge of the particle. And that makes the interaction between those 2D particles and "regular" 3D particles very weak. 

The sombrero model of the energy interaction between particles and black holes can explain 4 th. dimension. 

The thing that could make this model "real" could be the model where the energy hill around the black hole is like a volcano. In that model, there is the low- or zero-energy tunnel through the energy hill or the energy ditch around a very high energy level energy hill will pull particles out from the fourth dimension. 

Then that particle travels straight through that channel to the second dimension where it loses all its energy. That energy hill is so high that it touches the fourth dimension. When it pulls energy out from some point of it. That causes the effect that the particle falls through the 3rd dimension and then leaves into the base energy level.

Three red galaxies at the edge of the universe.

"These three "red monster" galaxies, found just 1 billion years after the hot Big Bang, are dusty, massive objects with more than 100 billion solar masses worth of stars inside. Unlike more modern massive galaxies, where no more than 20% of their gas has been converted into stars, these galaxies are two-to-three times more efficient, raising questions about how they formed and grew up to exhibit these apparent properties." (BigThink, What do JWST’s “red monster” galaxies mean for cosmology?)

The JWST telescope found three red galaxies. Those galaxies existed in the universe that was only one billion years old. And that can mean that those three galaxies cause the need to adjust the cosmological models. It's possible that Einstein's theories are not suitable for the young universe. The red color means that the galaxies travel straight away from us. And those galaxies might be on the opposite side of us. 

The big question is this. How those three galaxies could be so big? In some ideas, there could be some cosmic void around the supermassive black holes. That cosmic void could boost the black hole's pulling effect. The cosmic void around black holes can make material fall near black holes faster than just gravity allows.  

The cosmic void has a larger surface area than a black hole, and material should also fall into cosmic voids. And maybe that is the thing that made those galaxies grow faster than expected. In some models, the cosmic voids form the supermassive black holes. The cosmic void makes material fall into it. And in the middle of that thing forms the material center. 

Those galaxies have active black holes. And maybe there are stars. The heavy element formation needs only the impact waves or shockwaves that cause fusion. Things like supermassive black hole's relativistic jets can form heavier elements. As well as stars from them in fusion reaction. When elements impact each other and form new heavier elements we can always call that event fusion. 

In some models the Milky Way, our galaxy is in the middle of cosmic void. The size of that void would be about 2 billion light years. The thing that this void tells is this. There was some force like a very strong eruption in our supermassive black hole, Sgr A* that blew gas and dust away from around our Galaxy. 

That can tell that the Milky Way collides with some other galaxy. The impact between two supermassive black holes could turn the Milky Way and that other galaxy into giant elliptic galaxies. And then that form turned back to a spiral galaxy. 

That means light travels faster or without standard disturbance. If that model is true, the energy travels faster away from the Milky Way's edge than in normal galaxies. That means that this thing makes it necessary to adjust the cosmological models. The thing is that the Milky Way is not as typical a galaxy as we wanted to think. 

But the problem is that the young universe was different from the universe. Where we live. The density in the young universe was higher. The difference between energy levels were smaller. And that means energy moved slower in that hotter universe. Maybe those three red galaxies were the first galaxies that formed. Those galaxies named S1, S2, and S3 are interesting because they are so big. Those galaxies are larger and heavier than researchers think. 

The major question in the element formation is this. Did elements form before stars? That means: were there some other heavier elements that existed before the first stars were born? The model is that things like collimations. of neutron stars form heavy elements. So if we think that black holes existed before stars those black holes could collide and send shockwaves that can turn hydrogen also into heavy elements. 

The question about the galaxies and planetary formation is when the first planets start to form. Or rather, when the first solid elements formed. For a long time, people believed that the stars were the only things that could form heavier elements than hydrogen. But then researchers noticed. High-energy reactions can form heavy elements like gold and iron. 

The neutron star collimations make the pressure wave that forms fusion and those heavier isotopes. That means it's possible that a black hole's relativistic jets can also push light atoms like hydrogen against each other and form fusion and heavier elements. That means heavy element formation doesn't need stars. They need only an energy punch that creates the fusion. 

When we think about supernova explosions there the intensive pressure- or shockwave travels through the universe. That impact front creates the fusion reaction that can send energy into those bubbles. And that energy is the thing that pushes material and weaker quantum fields into the form that we call singularity. A black hole's plasma halo is an interesting thing. But the same way. We can think that the event horizon is the gravitational halo around the black hole.

Supermassive black holes are forming and ripping galaxies.

Image: NASA

The supermassive black holes are forming galaxies. But they also push material away from them. The interaction between black holes and their environment is more complicated than people think. When a black hole pulls material inside it the energy level of the material rises to an extremely high level. Part of that material travels to the poles of the black hole and impacts together. 

That thing causes very high power X- and gamma ray beams that are leaving from black holes or at least near that thing. When those radiation pikes hit the material cloud around the black hole it makes the material shine. That shine means that the plasma that forms the main part of the galaxy is sending radiation. 

What is the difference between interstellar and interplanetary nebulas? One description is that there are heavier elements like silicon and iron in the interplanetary nebulas. 

Interplanetary nebulas are the supernova remnants. And interstellar nebulas are mainly hydrogen and other light elements like helium. 

And that radiation pushes the plasma particles away from each other. So the supermassive black holes inside the galaxy are forming galaxies. But the energy that is left from the transition disk and material around the black hole also rips the galaxy into pieces. The jets of the black hole are transferring material away from galaxies but they are also forming the disturbance. 

Without those disturbances, forming of new galaxies is impossible. Same way cosmic disturbances like energy impacts are making it possible that protostars are starting to form. Stable systems cannot form stars. There is needed some kind of disturbance or asymmetry that is causing the formation of the stars. 

When the radiation of the exploding supernova or some cosmic eruption hits the interstellar nebula that causes the weight of the particles changes. This thing causes the effect where particles of the interstellar nebula start to go together. Forming of the star in a cloud that is mainly hydrogen requires that there is helium. In an interplanetary nebula, things like silicone or iron will start to grow the material around it. 

Or in some other heavier elements that are causing the gravitational center. Otherways the ionized hydrogen between atomic hydrogens is starting to pile the particles up. The formation of the stars requires that there is a gravitational center in the nebula. 

When bright stars are covering other stars

When bright stars are covering other stars

Barnard's star distance 6 light-years like in one computer game has been told has the planet. Super-Earth, what orbits quite near of this flare-star, which is quite near to us. And that thing is quite amazing because there have been found the Super-Earths around other stars, what is brighter and farther away from Earth than Barnard's Star. That thing makes sometimes people think that there is something wrong with this kind of object.

And people are asking, why the planets of Proxima Centauri, what is the nearest star of Earth found the only couple of years ago? Gliese 581 is quite a similar star with Proxima Centauri and the distance to that star is 20 light-years. And that exoplanet system is known better than the Proxima system.

Here I must ask one question,  is the Proxima Centauri worse observation target than some red dwarf at 20 light-years away from us? The double star or two brown dwarfs, what is orbiting together and forming the system known as Luhman-16 has been found in 2010, and that thing is quite interesting because Luhman-16 is nearer Earth than Wolf-359 what is 7,78 light-years from Earth and the brightness of Wolf-359 is 0,00002 suns.

Numbers are taken from Finnish Wikipedia. The distance to Luhman-16 is 6,6 light-years and the brightness is similar to Wolf-259. The first suspected exoplanet has been predicted to be near Barnard's star because that star was traveling weaving trajectory.  And that icy planet has been found recently.

But when we are thinking bright stars, we must realize that very bright blue stars are making searching the sun-type stars difficult, because those bright stars are covering the sun-type stars in their brightness. That's why finding yellow stars from another galaxy is impossible. This kind of thing is making the SETI-program difficult, because there is a possibility, that some galaxies would have only blue stars.

If we are thinking the opposite way there is a possibility that in some area of the universe, where is seem only bright blue stars could be only one suitable star for lifeforms, what are similar with Earth. But in this case, we must know, that those bright stars would cover the entire planetary system and even quite bright stars in the middle of them.

Or the star, what might interest SETI-program might be behind those bright stars or hiding behind galactic dust. The thing is that if we want to look for intelligent lifeform, that thing might be somewhere, where we cannot even expect. And the thing is that if those hypothetical advanced aliens would use quantum computers and communicate with qubits, those messages cannot be open for us.

The problem is that in the world is only a couple of radio telescopes or so-called high power telescopes. Of course, there is a lot of telescopes, but the universe is full of interesting targets, which are wanted to observe by using telescopes like VLA and Arecibo. The last one is the zenith telescope, and that means that it is in a fixed position in Puerto Rico. That means that the alien civilization should be in the line of that telescope if astronomers want to get the message from other civilizations and that means that they should have good luck.

Gravity and the limits of Einstein's theory

Gravity and the limits of Einstein's theory

One thing what we must understand, when we are creating texts and thoughts about black holes and forms of material behind the event horizon is that we can write and talk almost everything we want about that phenomenon. We cannot visit inside that object, because we don't have a single one near us. And because we cannot get any observations behind the event horizon, we cannot deny or prove a thing, what happens behind that point.

The observations are things that are proven or abandon theories. That is the thing, what we must realize when we are thinking about theories and scientific facts. Fact is the thing that gravity influences every object with the same way, and in the empty or vacuum chamber plume and bites, what are made of iron are dropping with the same speed.

And why the light doesn't drop to Earth. That thing is so fast, that Earth has so minimum influence to light, that we just cannot meter that difference. The black holes have so powerful gravity field that the escape velocity is higher than the speed of light, but the thing is that the transition disk around the black hole is so bright, that it denies making observations of the distant objects behind the black hole. The thing is that the gravitation lenses are proven that the gravity influences to light, but the thing is that also galactic molecular nebulas are causing the changes to the trajectory of photons. 

That's why the scientists must confirm that the errors or changes in the trajectories of photons are causing by gravity, not molecular nebulas. And that means that there is needed extreme sharp telescopes, what can eliminate the possibility, that the interstellar nebula is influencing the trajectory of light. Of course, there is needed enough massive target like galaxy, what is in the right angle, and in the point of the sky, where are only a few stars. That makes possible to search the double image of some quasar, what is in the same line with this galaxy.

If we would want to see what happens inside the black holes, we must travel inside them. This is the reason, why the theory of relativity is so confirmed. But there is one aspect, what we ever thought, and that is that inside the black hole might be multiple internal spaces, where the gravity is getting different geometrical forms. So what that thing, what I just wrote means?

The idea of the black hole is that the material would be pressured to the extremely tight, and that means that the form of a black hole is not material in the form how we understand the material. In the mind of some cosmologists, the black hole is only the gravitational field, what is firming in the giant energy burst, what releases when the giant star is blowing as a supernova. This is the normal black hole, buts then we must think how the supermassive black holes are forming? 

Those objects are forming that the interplanetary or interstellar molecule cloud is collapsing straight to the black hole and the thing what we are looking for in this thing is what is behind the event horizon? After that point, we cannot get any observations, and the only thing what we know is that the black holes are not growing.

Or do we know even that? When we are thinking about the supermassive black holes, what mass is about millions or even billions of masses of the sun, we might think that the black hole is growing but the increase of the size of this extreme object is so small, that we cannot even meter that thing. So this is about the growing black holes.

But there is another thing, what is ever thought when we are talking about black holes, and that is the powerful radiation zone around this object might blow a large mass of material away from the black hole. That thing is making one thing clear, and that is that there is a possibility to use black holes as a gravity sling. But we don't have a single one near us. So this makes that kind of things pure theory.
