If compared on a scale of scale, the Greenwich Meteorite Belt is comparable to the North and South Alpha Systems, but it lacks enough large objects. Pen? Interesting? Pavilion wWw. ｂiquge。 Of course, this is not to say that there are no large objects in the Greenwich meteorite belt, but they are scarce and no star systems have formed.

In the past few hundred million years, the objects in the Greenwich Meteorite Belt have been affected by the Alpha Galaxy in the north and south, mainly by the huge gravitational pull of the two star systems, and the main objects are concentrated in the north and south ends, that is, the central zone of the Greenwich Meteorite Belt has almost no objects, let alone large objects.

It's just that almost nothing doesn't mean nothing.

After hundreds of millions of years of evolution, the objects that have withstood the huge gravitational pull of the northern and southern alpha galaxies, and the objects that remain in the Greenwich meteorite belt have huge mass. In other words, only objects that remain in the center of the Greenwich Meteorite Belt are massive enough to remain unaffected by two star systems and have been stable for hundreds of millions of years. Obviously, only large black holes can meet these conditions.

In fact, in the past few thousand years, the Federation of Mankind has not figured out the number of black holes in the Greenwich meteorite belt, only a general statistic, between 10,000 and 100,000, and the black holes detected by humans are all large black holes, of which the mass of the largest one is equivalent to 1.5 million times that of the home galaxy, even the smallest is equivalent to 100,000 times the home galaxy, and the mass of the others is between 200,000 and 500,000 times that of the home galaxy.

For a long time, scientists in the Federation of Mankind have believed that it is the existence of these large black holes that has prevented the Greenwich meteorite belt from being torn apart by the huge gravitational pull of the northern and southern alpha galaxies, and has been stable for hundreds of millions of years. However, these black holes are scattered, and none of them is massive enough to dominate all the objects in the Greenwich Meteorite Belt, so the Greenwich Meteorite Belt has not been able to get rid of the shackles of the North and South Alpha Systems, that is, to become an independent star system. What's more, the total mass of these black holes that have been discovered by the Human Federation is not huge enough to be comparable to the central black hole of a stellar system even if they merge into a single black hole, so the Greenwich meteorite belt has not become the basic condition for an independent stellar system. According to the calculations of human federal scientists, in about a billion years, the northern and southern alpha galaxies will be able to capture all the regular objects in the Greenwich meteorite belt by gravity, and each will gain more matter, so that it will completely sever the relationship and no longer be associated star systems, and those black holes in the center of the Greenwich meteorite belt will become isolated objects. Escaping the influence of the North and South Alpha Systems, these black holes will become more secretive and difficult to detect, eventually becoming a death trap between the two star systems. However, while becoming isolated objects, these black holes will also lose the opportunity to capture other objects, and then gradually use up their energy in the long life of hundreds of millions or even billions of years, and finally disappear completely.

Of course, not only black holes, but all celestial bodies in the universe will eventually be completely wiped out.

Fortunately, no living creature has yet mastered the means to completely destroy a black hole without causing a catastrophe. In fact, with the exception of human civilization in the Second Age, no civilization has ever destroyed a black hole. In fact, for most civilizations, there is no reason to destroy black holes.

Although black holes are the most terrifying existence in this universe, capable of devouring all matter and energy, and compressing matter to the limit, thus completely destroying the internal structure of matter, black is an indispensable existence and a concern for the stable existence of the universe. Quite simply, the enormous gravitational pull produced by a black hole has an effect on all celestial bodies, thereby limiting the trajectory of individual celestial bodies. Without the confinement of black holes, the galaxies within the star system would gradually move away from each other because they could not generate a strong enough gravitational pull on their own, becoming lonely star systems, and the star system would also die out, eventually turning the transstar system into a collapsed star system.

In fact, in all the star systems observed by humans, there is a central black hole with an extremely large mass, and all the celestial bodies in the star system orbit around this central black hole. Of course, there are some special cases, such as some star systems with two or even more massive black holes, which form multiple centers, and the other celestial bodies in the star system move extremely complex around these centers. It's just that, no matter how special it is, there are black holes in any star system that are massive enough. This has also become the basis for judging the star system, that is, without a giant black hole, it is not a star system, and can only be regarded as a nebula.

Obviously, the most special existence of the North and South Alpha Systems.

It can be said that among all the star systems discovered by mankind, only the northern and southern alpha galaxies do not have a central black hole, nor do they have a black hole with a mass large enough to affect and bind all celestial bodies. It is precisely because of this that the scientists of the Federation of Mankind believe that the state of the North and South Alpha Galaxies cannot be maintained forever, and will inevitably undergo drastic changes at some point in the future, either a black hole with a large enough mass will appear in their respective central regions and eventually evolve into a central black hole, or it will gradually dissipate and eventually evolve into a chaotic nebula. However, if there is enough time, such as billions of years from now, the northern and southern alpha galaxies will definitely merge together again and give birth to a huge central black hole, which will eventually become a massive star system. It's just that before that moment comes, all the celestial bodies in the North and South Alpha Galaxy, and even all matter, will be completely destroyed, and everything now will be wiped out.

It's just that for humans, the Greenwich Meteorite Belt is a mysterious place.

Although the Human Federation has been on the Greenwich Line for thousands of years, resisting invasions from the north, it is limited by various factors, especially those ubiquitous and uncertain dangers, and scientists of the Human Federation rarely visit the Greenwich Meteorite Belt, let alone explore it in depth. In fact, humanity doesn't know as much about the Greenwich meteorite belt as we do about the North Alpha Galaxy. At least during the Fifth Greenwich War, scientists from the Human Federation followed the Human Legion into the North Alpha System, and at that time carried out a lot of exploration and scientific research with the aim of occupying the entire North Alpha System.

In most people's minds, the Greenwich Meteorite Belt is an empty and barren land.

For the human soldiers guarding the Greenwich Line, ready to engage the Silicon Charm army, the Greenwich Meteorite Belt is a natural wall and an obstacle to the Northern Alpha System. As for what the central area of the Greenwich meteorite belt looks like and what special existence there is, it is obviously not their concern. In a sense, the scientists and soldiers of the Human Federation do not know as much about the Greenwich Meteorite Belt as the mercenaries operating here, because those mercenaries will go to the Greenwich Meteorite Belt to save their lives and make discoveries, and they will explore the situation of the places they pass through and understand the unknown after going deep into the Greenwich Meteorite Belt.

In fact, before the outbreak of the Sixth Greenwich War, the Human Federation's understanding of the Greenwich Meteorite Belt mainly came from these mercenaries who risked their lives, as well as interstellar pirates who were even more desperate than mercenaries. In the 1,000 years since the end of the Fifth Greenwich War, the Human Federation has not sent legions deep into the Greenwich Meteorite Belt, either for its own reasons or due to external restrictions.

Obviously, it is difficult to grasp the situation in the central area of the Greenwich meteorite belt just by observation.

The consequences of this were already evident in the Sixth Greenwich War. That is, when the human expeditionary force led by Yang Yi launched a counterattack, they only mastered a route through the Greenwich meteorite belt to the North Alpha Galaxy, and only mastered the situation near this route. Even if it were to be centered on the route and spread out a hundred light-years in all directions, the route would cover less than one-ten-thousandth of the area of the Greenwich Meteorite Belt. As for what lies beyond here, the Human Expeditionary Force not only does not understand, but also cares nothing. At least until Yang Yi planned to build the Greenwich meteorite into a base for human civilization, no one cared about anything beyond the shipping route.

Unfortunately, soon after Yang Yi had this idea and took action, the Phantom Ghost Emperor took action to destroy all the large celestial bodies in the Greenwich meteorite belt.

However, the Greenwich Meteorite Belt did not die out as a result, and its influence remains, that is, it still connects the northern and southern alpha galaxies. The point is that 99 percent of the total mass of all objects in the Greenwich meteorite belt is black holes, and the 10 largest black holes account for almost 10 percent. It is the existence of these black holes that allows the Greenwich meteorite belt to have a large enough gravitational pull to maintain the associated relationship between the northern and southern alpha galaxies after the loss of other celestial bodies. It's just that because all the large celestial bodies have been lost, they can't provide a reference node for space jumps in a span of nearly 10,000 light years, so space travel through space jumps is not possible.

It can be said that only by destroying these black holes can the Greenwich meteorite belt be completely wiped out.

It's just that the Phantom Ghost Emperor obviously doesn't have such strength, and all she can do is make the North and South Alpha Galaxy distant enough at most.

Of course, for ordinary creatures, black holes are off-limits. Even the War Emperor of the Silicon Charm Alliance, or the Emperor-level powerhouse of the Galactic Alliance, did not dare to approach the black hole rashly, let alone enter the black hole. In addition, the sheer mass of black holes, as well as the spatial distortion caused by gravitational pulls so powerful that even light cannot escape, allow state-of-the-art space-jumping devices to become ornaments, making it impossible to use black holes as a reference for space-hopping. In fact, when making space jumps, it is necessary to avoid overly massive objects, let alone black holes. It is important to know that the ultimate speed of most spacecraft is only one-tenth of the speed of light, so when you get close to the black hole, you will be captured by the black hole's gravity.

Fortunately, only the creatures born in the universe and the ships built by those creatures are limited. (To be continued.) )
