Chapter 453: The Birth of a Black Hole!

The internal space constructed by this unknown silicon-based civilization inside this neutron star is not too large, but you must know that the diameter of a whole neutron star is only 20 kilometers.

The weird wall disappeared, and the neutron star matter collapsed instantly. The speed at which they collapse is extremely close to the speed of light, the extremely large mass, and the extremely fast speed allow them to carry extremely large kinetic energy. After impact, there is rebound.

This is similar to the mechanism of a supernova explosion. The supernova explosion is because the core of the star suddenly loses its support, and the outer stellar matter collapses, collides, and rebounds, and finally blows up the entire star. Now, this scene is repeated on this neutron star. up.

The force rebounded from the impact spread to the entire neutron star, but unfortunately, the force of this collision rebound was not enough to allow the matter on the neutron star to gain an initial velocity sufficient to escape the gravitational field of the neutron star, so this neutron star did not Instead of being blown to pieces, it fell into instability.

Inside the neutron star, earth-shaking changes are taking place, and on the outside, the intensity of radiation in various wavebands increases again.

When I was on the earth, someone once studied a very interesting topic, that is, if the short lifespan of the miniature black hole is ignored, that is, assuming that a miniature black hole can exist for a long enough time, when it meets the earth , What kind of model will it use to swallow up the whole earth?

The result of the research is that when the black hole meets the earth, since the earth is stronger than the black hole in terms of overall gravitational force, the black hole will first revolve around the earth and then fall into the earth , eventually sinking to the core of the Earth. Due to inertia, it will not be stable at the center of the earth. Instead, it will continue to move, and in the process of moving, it will constantly devour the matter of the earth. It's like a mouse that got into the cheese and devoured the whole cheese from the inside.

Of course, in reality, the collapse of the planet and various radiation issues also need to be considered, but this is generally the case. Now, the scene is being recreated during the encounter between the neutron star and the white dwarf.

White dwarfs are relatively large in size. It has a volume about the size of the earth, but the volume of the neutron star is very small. Compared with the volume of the white dwarf, it is like the comparison between half a sesame seed and a large millstone. The density of neutron stars is much higher than that of white dwarfs, so at the moment of meeting. It drilled directly into the white dwarf, leaving a huge hole above the white dwarf.

this cave. It leads directly from the surface of the white dwarf to the center of the white dwarf. The substance that originally occupied the cave. At this moment, it has been swallowed up by the neutron star, transforming from white dwarf matter to neutron star matter. The consequence of the increase in density is that the volume shrinks, so such a cave appears.

The next moment, under the action of the white dwarf's own gravity,

The cave disappeared quickly again, sealing off the escape route of the neutron star. But the devouring action of neutron stars will not stop. It is in the core of the white dwarf star, devouring the matter of the white dwarf star, converting the mass of the white dwarf star into its own mass. It's like a ferocious mouse running into the middle of a huge hunk of cheese. It is constantly biting the quality of this cheese from the inside.

This is a very violent collision process. At the moment when the neutron star meets the white dwarf material, the huge energy erupted by the collision completely changes the material structure here. During these few moments, a series of indescribable and complex material changes took place. Some substances have been changed directly from the nuclear level, and they have become various metal elements. Among them, there are gold, silver, platinum, radium, uranium, and mercury... At this moment, all the elements on the periodic table of elements have been produced, no matter the light elements that are ranked before iron, It is also a heavy element after iron.

The fusion mechanism inside the star can only produce iron and the elements before iron. After the fusion produces iron, the doomsday of the star will come. What greets it will be a supernova explosion. The supernova explosion can be regarded as death or death. It is creation, because only in supernova explosions, heavy elements after iron can be produced. It is for this reason that iron and the elements before it are relatively abundant in the universe.

This point is also very obvious on the earth. Why are the elements at the back of the periodic table, the rarer the reserves? Why is the reserve of silver element so much less than iron element, but so much more than gold element?

The reason is simple, because silver is heavier than iron and lighter than gold. Because in the universe, it is very easy to make iron, so there is a lot of iron. Gold and silver are relatively difficult to make, so they are rare.

An event as violent as a neutron star colliding with a white dwarf would undoubtedly meet the criteria for creating heavy elements. So at the moment of the collision, all the elements were produced, and all the elements that were on the periodic table were produced. And because of the huge energy brought by the collision, they gained enough initial velocity to escape from this huge gravitational field, so they splashed out from the collision, flew into the universe, and participated in the slowness of the universe. Evolving. Maybe the gold produced in this collision will be taken by a creature in a certain elementary civilization to exchange for some food they need, and some of the gold produced in this collision Uranium will be used by some scientists of this elementary civilization to make atomic bombs...

During this collision, some extremely heavy elements were produced. There is no way for these extremely heavy elements to exist stably, so in a very short time after being thrown out, they lose some protons or neutrons that make up their atomic nuclei, and eventually decay into other elements.

Accompanied by these ejected substances, leaving these two stars together is extremely intense radiation, which is also the most terrible disaster in the universe, the gamma ray burst.

In addition to these, there are extremely strong bursts in the visible light band. At this moment, these two stars released light that was stronger than the explosion of the main star in the capital galaxy of Merian Civilization. Under the light pressure of these lights, Xiao Yu saw a shocking phenomenon.

This planet, which was used as a shield by itself, was actually pushed away from its current orbit by the light pressure, and began to move backward. Fortunately, Xiao Yu reacted quickly enough, and immediately manipulated his fleet to move with the planet, so he was not directly hit.

Xiao Yu once again saw the powerful power of a cosmic disaster. If it weren't for this planet as a shield, he would have died long ago, and even the four protective shields couldn't stop such a violent energy burst.

Although the energy of the gamma ray burst is powerful, it can only last for a short time. Basically, it only lasted about three seconds when the impact just happened, and then continued to rush into the void at the speed of light up. During the long propagation journey, it will gradually lose its own energy, but it is certain that even in places billions of light-years away from here, after the energy of this gamma-ray burst arrives, it can still be clearly observed.

The energy of the gamma ray burst is mainly erupted along the two ends of the neutron star's magnetic poles, where the energy is the strongest. If there is a biological planet in the direction where the two ends of the magnetic poles are facing, even if the distance is Thousands of light years away, those creatures will be killed without accident. The energy of gamma-ray bursts in the direction of non-magnetic poles is smaller, but it is still enough to kill any unprotected life within a distance of tens of light-years.

Xiao Yu naturally avoided the direction of the magnetic poles, but even so, the planet that he used as a shield received extremely serious damage. Xiao Yu could not specifically describe the specific mechanism of these damages, because there are still many things that Xiao Yu has not yet understood about extreme events such as the collision of white dwarfs and neutron stars. Xiao Yu only knew that the planet in front of him was undergoing the baptism of violent energy. On this planet, earthquakes occurred frequently, magma flowed across, and the strong orogeny almost completely changed the planet's landscape.

The collision process is still not over. This neutron star has come to the interior of the white dwarf and is eating away the material of the white dwarf from the interior. Having lost enough material support, the overall structure of this white dwarf is collapsing, and its volume is shrinking rapidly. It's like a piece of fluffy bread is being squeezed hard by a big hand.

The difference is that the force of the bread being squeezed comes from the outside, and the force of shrinking the size of the white dwarf comes from the inside. The collapse of matter means that they will fall on the neutron star, which means that there will still be impacts and strong energy will be released.

This energy is very strong, but most of it is confined inside the star and has not fully exploded. Even so, a little leaked energy is enough to change the color of the world.

Xiao Yu knew that something terrible was happening inside the white dwarf. Xiao Yu had already predicted the outcome of this matter. Xiao Yu knew that the final creation should have been formed at this moment. If I didn't make a mistake in my estimation, the neutron star should have disappeared at this time.

Instead, it should be a black hole. A black hole is enough to devour everything, and it cannot come out after entering. The most terrifying black hole in the universe is hiding inside this white dwarf at this moment, and is rapidly increasing its mass. (To be continued..)
