The Galactic Center is a very dangerous place. Even if Xiao Yu has now reached the level of sixth-level civilization, this has not changed. Because there are too many extreme celestial bodies in the Galactic Center.
This phenomenon is easy to understand. Under the gravity of the earth, heavy things will sink, and light things will rise relatively. However, under the gravity of the black hole in the center of the galaxy, dense celestial bodies with extremely high density will gather in large numbers toward the center of the galaxy.
, relatively light stars, planets and other stars will be in the periphery, these principles are the same.
The Galactic Center is the place with the highest density of stars in the entire Milky Way. There, the density of stars can even reach the point where dozens or dozens of stars gather within one light-year. These crazy multi-star systems are mixed with stars.
Various extreme stars, while rotating crazily around each other, are also orbiting around the large black hole in the center of the galaxy.
That's right, there is a supermassive black hole at the center of the Milky Way. Its mass can reach millions of times that of the sun. It controls the operation of the entire Milky Way, allowing the Milky Way to clump together without falling apart.
The existence of supermassive black holes is the main force that created the universe. The reason why the universe is formed like this, where galaxies are gathered together, but without a star here and a star there, it becomes a loose sand, mainly because of the gravitational pull of supermassive black holes
for the sake of.
With the development of science and technology to this day, Xiao Yu has a profound understanding of the truth, that is, every kind of life is a legend, and it develops under the influence of many factors. For example, human beings, if not for
Many billions of years ago, there was an exploding supernova near the solar system that provided enough heavy elements for the emergence of human beings. Human beings would not have appeared. And without the supermassive black hole in the center of the Milky Way that brings together so many stars in the Milky Way.
.Allowing communication between different substances, it is impossible for humans to appear.
If there were not a few outer giant planets in the solar system and the moon with a disproportionately large mass to shield the young earth from crazy asteroids from outer space, life on earth would be destroyed as soon as it appeared. If there was no moon to create
Tidal gravity allows the material on the earth to be fully exchanged, and life cannot appear on the earth.
There are many, many similar conditions, too numerous to mention. It was under such numerous conditions that life on earth appeared, and eventually intelligent creatures like humans evolved.
But among all these prerequisites, the supermassive black hole in the center of the galaxy is the biggest prerequisite. In a way, human beings, no, all native creatures in the galaxy can be counted as this black hole
Descendants. Because there is no central black hole, life cannot appear in the Milky Way.
Now Xiao Yu, with a complex mood similar to a pilgrimage, was driving quickly towards the center of the galaxy.
More than a hundred years after the warp voyage began, Xiao Yu witnessed with his own eyes the destruction of a star in the small universe.
This star was originally a yellow dwarf slightly larger than the sun. It emitted amazing light and heat all the time. But the stellar energy acquisition equipment made by Xiao Yu was constantly stealing its mass, its mass
, decreasing at a rate of about eight thousandths per year. The reduction in star mass will lead to a series of subsequent events.
First of all, because the mass decreases, its internal pressure will also decrease. When the pressure decreases, the temperature will also decrease. The primary triggering condition for nuclear fusion is temperature. The higher the temperature and the greater the pressure, the more nuclear fusion reactions it will undergo.
The more violent it was, the more energy it released. As Xiao Yu continued to steal its mass, Xiao Yu saw that its luminosity was constantly decreasing, becoming dim, and gradually starting to change from yellow to dark red.
This means that its surface temperature is decreasing, which means that its radiation ability is weakening. Xiao Yu continues to steal its mass, and its color becomes redder and redder.
Finally, due to the loss of mass, the star changed from a yellow dwarf to a red dwarf. At this time, Xiao Yu still did not stop stealing mass, so it began a new round of transformation, and the energy it released
The red light began to gradually dim.
It gets darker and darker, until now. Today is a node, because starting from today, because the mass is too low to bring enough pressure and temperature, the nuclear fusion reaction in the core of this star finally stops.
Without the nuclear fusion reaction, which means that it can no longer release light and heat, it can no longer be regarded as a star, at least it is no longer a star in the true sense.
Xiao Yu left behind hundreds of millions of images of this star, completely recording its entire process from a young star to a brown dwarf that cannot emit light. This star could have been around for tens of billions of years.
He spent his long life peacefully in the universe, eventually turning into a red dwarf star, and then spreading into a planetary nebula, leaving a white dwarf star as his corpse in the universe. But under the influence of technology
Under this, its destiny was completely and completely changed. In more than a hundred years, it hurriedly completed the remaining life span that originally took at least 8 billion years to complete, and even its own
No corpses can be left behind.
Xiao Yu retrieved two photos from his mind. In the first photo, the star was still emitting a faint light. Although it was extremely weak, it was eliminated through extremely sensitive optical instruments.
After the influence of other stars in the small universe, it can still be captured. In the second photo, this star no longer shines at all.
In the first photo, that faint red light seemed to be the most desperate but weakest accusation against Xiao Yu, the murderer who killed it.
Under the power of technology, a star is nothing at all. A war of a level-6 civilization may affect hundreds of stars and lead to their destruction. Even a level-5 civilization, in order to pursue and intercept the alliance of level-5 civilizations,
Xiao Yu once transported more than a dozen stars and deliberately detonated them to cause damage to the fifth-level civilization alliance.
In the face of technology, stars that were once majestic are gradually becoming weaker and turning into pitiful things that can be held in the palm of a civilization and destroyed wantonly.
"Perhaps, it is precisely because of this that the universe hates the existence of civilization and that thing called luck appears." Xiao Yu looked at the dead star and thought silently in his heart.
Xiao Yu once again personally destroyed a star, turning it from a real star into a brown dwarf.
A brown dwarf is an intermediate body between a planet and a star. It is neither a planet nor a star, or it is a super-large planet and an incomplete version of a star. A brown dwarf cannot perform hydrogen fusion, but inside it
At some locations, a certain degree of deuterium fusion may occur. Because deuterium fusion requires lower requirements than hydrogen fusion. However, the scale of this nuclear fusion is too small and can be ignored.
Xiao Yu still did not stop destroying the star, and Xiao Yu continued to steal its mass. In the end, the temperature and pressure inside the star could no longer sustain even the simplest deuterium fusion, and it completely broke away.
The stellar category has completely returned to the planetary category.
The star at this moment, like Jupiter in the solar system, has transformed from a star into a giant gaseous planet. The main components of stars are hydrogen and helium, and the main components of giant gaseous planets are also these two elements.
element, so apart from their mass, there is essentially no difference between stars and giant gas planets. Therefore, when the mass of a star is reduced to a certain level, it will become a planet, and when the mass of a planet is increased to a certain level, it will become a planet.
Become a star. The two can transform into each other.
Now Xiao Yu has completed this transformation process. As the star's mass and volume continue to decrease, Xiao Yu has assigned a large number of mass-stealing instruments to work around other stars. Now this star has become
A real planet was discovered, but Xiao Yu still had no intention of letting it go.
There is no need for a gaseous planet to exist in a small universe. It is not like a star that can provide energy for Xiao Yu, nor is it like a rocky planet that can be inhabited by intelligent creatures. It has no value to Xiao Yu. The only consequence of having no value is that
It was completely destroyed by Xiao Yu, leaving nothing behind.
As a result, those mass-stealing instruments continued to work around the planet until all its mass was completely stolen without leaving any residue behind. Then they left here and were assigned by Xiao Yu to move around another star to continue.
this task.
An extremely brilliant star has completely lost its trace in the universe. Its purpose of existence is just to allow Xiao Yu's huge fleet and the entire small universe to advance nearly three thousand light years by sailing at a curvature.
At this moment, Xiao Yu controlled a huge fleet and a small universe to stay around a star system. Because advance detection showed that there were a large number of certain precious elements that Xiao Yu urgently needed in this star system, and Xiao Yu needed to carry out research here.
After some supplies, we set off on the road again.
At this time, Xiao Yu received a message transmitted through space broadcast.
"Although it is very presumptuous, we still send this request to you. No matter which civilization receives this message, if you are a sixth-level civilization, then we hope that you can help us... In return, we
We are willing to hand over this small universe... We are the Pegasus civilization."
