Start sweeping the universe by rubbing the CPU with your hands.

The exercise fleet has already set off, and Han Yang has truly left all relevant matters to the human military leaders, while he devotes himself wholeheartedly to technological research and development.

In addition to building a large number of large scientific facilities and trying his best to simulate some extreme environments in the universe to study the strange phenomena that occur in such environments, Han Yang also attaches great importance to the observation of the actual cosmic environment.

Certain star systems have environments that are very different from those in the solar system and that are difficult to reproduce with simulation devices. They are of great scientific research value and are of great significance for both basic and applied scientific research.

At this moment, with Han Yang's semi-participation, a scientific research fleet consisting of one scientific research ship, two transport ships and 20 warships arrived at the Weiss 0855-0714 system.

This star is the fourth closest star group to the sun. Calculated as a single star, it is the seventh closest to the sun.

This is a very special star.

The reason why we call it a "star" instead of a star is because this star is too special.

It is so small that its mass is only about 6 times that of Jupiter. Brown dwarfs are far more massive than even the smallest star species.

In this respect, it appears to be a planet, a rogue planet.

But it is an independent entity, with no stars around it. As for a planet, its mass seems to be a bit too large.

After comprehensive consideration, human scientists finally classified it as a "sub-brown dwarf", which is a star smaller than a brown dwarf.

In Han Yang's view, this should actually be regarded as an incomplete star.

Han Yang speculated that it may be that in the early stages of the star's evolution, the amount of nebula material was insufficient, preventing it from accumulating more mass and eventually igniting nuclear fusion to become a star, or that it may have been affected by some external factors in the early stages of its formation. Impacts, such as supernova explosions and neutron star collisions, cause the nebula material to be blown away.

Or perhaps in the early stages of formation, there was another protostar competing with it for nebula material, and then the two stars were separated by gravitational disturbance, ultimately creating such a freak.

The specific reason still requires further on-site observation by the scientific research fleet.

But no matter what the reason is, studying such stars will be of great benefit to Han Yang's stellar evolution theory, cosmological theory, stellar physics, planetary physics, etc., and even to the basic science level.

This scientific research fleet slowly slowed down and finally docked in an orbit about three million kilometers away from the sub-brown dwarf.

What appeared in front of the scientific expedition personnel was an extremely magical scene.

This sub-brown dwarf cannot shine like an ordinary star because it has not ignited nuclear fusion. But it's not like there's no light on it.

In front of the scientific expedition personnel is a vast and deep universe, dotted with stars. And among these thousands of stars, there is a dark area about the size of four or five moons, in which strips of light blue light frequently appear, fleetingly.

Whenever a light bar appears, a slightly dark spherical figure will vaguely appear around it. The light bar disappeared, and the spherical figure also disappeared.

It is like a ghost, looming in space.

Han Yang knew that those strips of light were actually lightning that erupted in the atmosphere of this sub-brown dwarf star. An incredibly powerful thunderstorm that is millions of times more powerful than the most powerful thunderstorm on earth.

Even the most powerful battleship of human civilization, the asteroid-class battleship, cannot withstand a single blow from such a thunderstorm.

Lightning is enough to illuminate a range of tens of thousands of kilometers, so you can imagine how powerful it is.

The scientific research fleet parked, and then a small spacecraft set off, escorted by several battleships and slowly approached the planet.

Entering the outer reaches of its atmosphere, where the density of the atmosphere is equivalent to about one thousandth of the Earth's surface, the small scientific research vessel stopped.

What was presented to Han Yang at this moment was an even more astonishing sight.

He saw countless dazzling tree branch-shaped lightnings, born about thousands of kilometers below his feet, and then violently transmitted downwards until they hit invisible places deeper.

There are so many lightnings that never stop, almost turning this dark planet into a lightning jungle.

In addition to the thunderstorms, there were strong winds.

The windiest planet in the solar system is Uranus, where super winds with wind speeds exceeding five times the speed of sound blow all year round. And the winds on Uranus are nothing compared to this sub-brown dwarf.

Han Yang saw that the speed of the atmosphere on this planet was even more than 20 times the speed of sound, that is, more than meters per second.

Even if an asteroid-class battleship is hit by such wind, it will be torn apart instantly. Even the most advanced wind tunnels on earth cannot blow such powerful winds.

Perhaps because of the geothermal heat, Han Yang also saw that there would be rain and snow inside this star.

Gases such as methane and carbon dioxide gush out from the interior when heated and rise to high altitudes. After cooling down, they condense into ice particles or snowflakes and then fall back down.     Originally, this was a beautiful scene. But now with all these high winds and thunderstorms, it's not so pretty.

The snowflakes here can really punch a hole in the human body when they hit it.

Although the environment here is harsh, the scientists are all excited.

There are so many things to study about such a planet that is completely different from any other star in the solar system.

It can be said that if we do not produce more than 100,000 high-quality papers, this trip will be in vain.

Thousands of experts from various disciplines in the scientific expedition team were in high spirits and settled down next to such a demon-like planet to start long-term work.

On the other side, what Han Yang paid more attention to was a star system that was very famous in human history.

Sirius.

"Look northwest and shoot at the Sirius" expresses so much heroic spirit.

At this moment, the scientific research fleet belonging to human civilization arrived at Sirius.

The most important reason why Sirius is valued by Han Yang is that there is a special star in this star system.

white dwarf.

White dwarfs are a product of the final stages of stellar evolution. For a medium-sized star like the sun, when it reaches the end of its life and a large amount of hydrogen is consumed, it will turn into a red giant and gradually expand, but its core will be compressed, the material density will increase, and eventually it will become a white dwarf.

The material that makes up a white dwarf is extremely dense. One cubic centimeter of white dwarf material can be as high as one ton, which is about a million times the density of water.

The volume of the sun is hundreds of thousands of times that of the earth. If the sun is compressed to the size of the earth, it will form a white dwarf star.

Such an extreme star must have many extraordinary physical phenomena on it. Studying it at close range will also help Han Yang increase his research and understanding of basic physical theories.

In the vast universe, a huge blue-white star, dozens of times brighter than the sun, and an extremely small, but equally bright and dazzling white dwarf star emitting white light revolve around each other.

During this process, powerful radiation and charged particle streams swept across the entire galaxy, making this place like purgatory and completely unsuitable for life.

Even with adequate protection, the human scientific research fleet still cannot stay inside the galaxy for a long time. They can only dock at a place tens of billions of kilometers away, and then launch a large number of detectors to conduct close inspections, or send manned spacecraft to enter and observe for a short time.

But even so, there are still countless incredible and strange phenomena that have never been discovered before.

It's like the magnetic fields of two stars interacting with each other, creating a layer of extremely high-temperature plasma at a distance of tens of billions of kilometers;

Or the white dwarf is hit by comets, asteroids, interstellar dust, etc., and releases short-term intense X-rays and gamma-ray radiation - scientific research experts believe that this has a certain similarity with gamma-ray bursts;

Or maybe the stellar convection of Sirius A, a blue star, shows some abnormality that is inconsistent with the theory. Experts believe that there may be a connection with the white dwarf companion star. There is suspected to be some unknown interaction mechanism between the two stars. …

Thousands of scientists also settled here and began research.

In addition to these two stars, the others, such as Barnard's Star, Lutan's Star, Tianyuan 674, Procyon, Persia 1002, Tiancang V, Van Manen Star, GL, GJ, Tianchu , Wang Liangsan, Stars of the sixth magnitude of Peacock have scientific research fleets arriving.

In star systems where no scientific research fleet has arrived, there are also relatively large unmanned exploration fleets arriving.

Today's human civilization, under the leadership of Han Yang, has truly made scientific research its top priority.

Another event worth mentioning is that after more than two hundred years of peaceful development, the population of human civilization has shown a trend of explosion. Compared with the time when independence was first achieved, the population has increased more than five times, reaching 1000. Over million.

Regarding the population, Han Yang's original idea was that the more, the better. After all, the larger the population base, the more talented people who can become scientific workers can be born, and the greater the scientific research power will be.

However, after the population increased to over 1000 billion, the growth rate actually began to slow down, and even showed a downward trend to some extent.

This phenomenon attracted Han Yang's attention. After a little research, Han Yang confirmed that the population of human civilization may not be able to grow again.

"Sociology is also a science and has its own inherent laws. The second level of civilization can only support so many people at most."

Han Yang secretly sighed: "No wonder it doesn't matter whether it is the original Eta civilization or the Yuanshan civilization, the total population is less than 1000 billion.

The population of human civilization can exceed 1000 billion, and it is because of my existence. Without me, there would be at most to billion people. "(End of chapter)
