Chapter 2393 A red giant star?

Chen Tang has been in the Great Realm of Kyushu for two years. Even when he was on the secular earth, he was very interested in astronomy. In the early days, he used some popular science books to study various celestial bodies in the starry sky for a period of time.

I don't dare to call myself an astronomer, but at least I can be considered a fan of this field, and I am by no means a novice in astronomy...

But even so, he was still taken aback when he suddenly saw this star appearing in the distance in the starry sky ahead, and was stunned on the spot.

Because it is clearly a red giant star.

A red giant is actually a star. To be precise, it is a star that has entered a period of decline.

The surface temperature of stars entering this stage is relatively low, only a few thousand degrees, but their volume can expand to tens or even hundreds of times that before this stage.

Ordinary stars are already extremely large, and when they expand to such a degree, it is conceivable how terrifying their volume is.

Because the stars at this stage look red in color and are huge in size, they are called red giants.

When a star passes through its long young adult period, also known as the main sequence star stage, and enters old age, it will first become a red giant star.

A red giant is a short, unstable phase that a star goes through at the end of its burn, lasting only a few million years, depending on the mass of the star.

This is very short compared to the stable period of billions or even tens of billions of years for stars.

That's why red giant stars are extremely rare in the vast starry sky... That's why Chen Tang was so shocked at the moment.

After a short period of sluggishness, his figure came back to his senses with a shock, his face was still shocked, but his eyes showed unprecedented vigilance.

A red giant is extremely dangerous because it is unstable and still evolving...

The reason why a star burns blazingly, glows and heats up is due to the great change thermonuclear fusion that has always existed inside it.

Nuclear fusion occurs primarily in its core, where the radiation pressure is balanced by the gravitational pull of its own contraction.

However, the burning of hydrogen inside the star is extremely fast, and a helium core is formed in the center and continues to grow.

As time goes on, there is less and less hydrogen around the helium core, and the energy generated by the central core is no longer enough to maintain its radiation, so the balance is broken, and gravity prevails, and the star with the helium core and hydrogen shell is under the action of gravity will shrink and collapse.

This process of core contraction and shell expansion is the process of a star transforming into a red giant star. In the life of a star of billions of years, it only lasts for hundreds of thousands of years.

The final evolution result of the red giant star is either that the star body collapses toward the center of the star core to form a white dwarf star.

Or, it mutates during the gravitational contraction of the star, becoming a neutron star in the variable star category, or even a neutron pulsar, or even completely collapses into a black hole...

The red giant star in front of me is evolving towards one of these two endings. It may take tens of thousands of years to reach the final step, but it may be at the next moment.

The huge star body of a red giant star collapses in an all-round way. It is conceivable how dangerous it is when the gravitational contraction occurs, and the extremely vast starry sky will be affected.

If he happened to be in this starry sky again, who would dare to take it lightly?

Chen Tang asked himself, if he encountered such an extremely unstable red giant star in the starry sky that might collapse at any time, he would definitely stay away from it immediately...

But at this moment, he realized that there are actually quite a lot of people who don't want to die.

Because just around the red giant star far away in the starry sky in front of him, he clearly saw huge starry sky work platforms, on which not only were there various equipment, but also some figures were faintly visible.

These operating platforms are huge in scale, and the smallest one has a diameter of tens of thousands of meters and is divided into many layers. It is absolutely impossible to build it overnight.

The only reason why these guys are willing to take such a big risk to build such a large-scale operation platform around an extremely unstable red giant star is that the benefits are too huge, enough to make them take the risk, even ignoring their lives.

Moreover, judging from the fact that there are various instruments and equipment on each of these giant operating platforms, many Chen Tangs can't even name them, and they can't see their functions. It is obvious that the builders of the platforms are collecting some kind of energy here.

And this kind of energy must be related to this red giant star, otherwise, why build the platforms in such a dangerous place?
These thoughts flashed through his mind, and Chen Tang's curiosity suddenly became stronger. After taking a deep breath to calm down his mind, he shook his body and continued to move forward.

He decided to investigate first to see what kind of energy or matter these giant platforms are collecting around a red giant star, willing to take huge risks.

After getting the result, go to the remote area, take out the small fort on the other side, and peel off the second layer of energy from the two balls of light.

And through data analysis, determine the specific coordinates of what Wen Jiyue and the taboo layer are looking for when they entrust themselves to enter this interlayer of planes...

Of course, it is definitely not an easy task to sneak into these giant operating platforms and find out.

Although the starry sky powerhouses who actually manipulate the operations on the platform have the existence of the eleventh stage or even the tenth stage, almost every platform can see the ancestors of the thirteenth stage and even the fourteenth stage. level exists.

Even if there are no strong figures of this level on some platforms, it does not mean that there are no inside cabins of the operating platforms...

Building a giant platform in this place where giants gather, without the ancestor-level combat power to sit in it, I am afraid that it has long been expelled or even annexed by the old monsters on other operating platforms.

Chen Tang knew this well, so he didn't dare to take it lightly...

When he was still very far away, Chen Tang had activated his spiritual power, covering his whole body, concealing his body shape and aura.

Even so, he did not immediately enter a certain platform, but kept his body and aura in a state of restraint, wandered around the outer starry sky of the red giant star, and placed more than [-] giant operating platforms. Observed it again.

These more than [-] giant operating platforms obviously belong to different forces, and some platforms have logos, which can determine their backgrounds.

Some platforms do not have it, and it is not known what force it belongs to.

Among them, on the more than a dozen platforms with logos sprayed on them, Chen Tang didn't recognize more than half of the logos, and he had never seen them in the Kyushu world, which made him extremely suspicious that they came from the main universe.

As for the few logos that Chen Tang knew, one belonged to the Tianji clan and the other belonged to the Jinlin clan. They all came from the main universe, which basically proved his guess...
