The so-called variable stars, as the name suggests, are stars that can change their luminosity. There are such stars in the universe whose luminosity is not stable, but will suddenly change their brightness at a certain moment.
There are two types of variable stars, one is pulsating variable stars and the other is explosive variable stars. While in the Eagle Nebula, Xiao Yu manipulated a satellite to impact the white dwarf star, thereby triggering the white dwarf star's nova explosion, resulting in this
The brightness of the white dwarf increases tens of thousands of times in an instant. This is a typical explosive variable star.
In addition to this white dwarf accident, the process of supernova explosion of aging stars into neutron stars or black holes is also a formation mechanism of variable stars. In ancient China, a supernova explosion was observed, and that explosion created the famous Crab Nebula.
When a supernova explosion occurs, its luminosity increases by more than 100,000 times. In the sky at that time, there will be two moons at night. Its luminosity can even be seen during the day. This is an explosive variable star.
.
A pulsating variable star is a star that changes its own luminosity due to its internal mechanism during its own evolution stage. This red dwarf star obviously cannot be an explosive variable star, so it can only be a pulsating variable star. However, after a simple analysis,
Xiao Yu discovered one thing, that is, this red dwarf star cannot be a pulsating variable star.
It is neither an explosive variable star nor a pulsating variable star, so what exactly causes its luminosity to change?
Xiao Yu first ruled out the possibility of luminosity changes caused by interstellar dust obstruction. Because interstellar dust cannot block infrared rays, if it was caused by interstellar dust occlusion, when the luminosity in the visible light band changes, the light in the infrared band should remain stable. But Xiao Yu
Yu saw that the visible light and infrared light of this red dwarf star fluctuated according to a certain pattern at the same time.
Xiao Yu showed great interest in this.
"Is it due to some mechanism that I have no control over that causes this abnormal luminosity change? If this is true, it is a big discovery. Maybe I can develop a new theory from this.
.”
Xiao Yu enthusiastically arranged tens of thousands of spacecraft into an array of telescopes, and pointed the lens at this unremarkable red dwarf star.
When he observed the abnormal luminosity changes of the red dwarf star, Xiao Yu keenly noticed that the ghost family attached to the star seemed to have some fluctuations. Its slight movement caused the entire star to become violently active.
At this moment, the intensity of the star's stellar wind increased by at least a hundred times.
"Senior, what's wrong with you? Is there something wrong?" Xiao Yu asked with some confusion and worry.
The ghost clan's answer was a little hesitant. After a while, it replied: "It's okay. After a long rest, you always need to move your body a little. Well, during this period, how has your technology progressed?
Like? Did something happen?"
"Senior, thanks to your generous protection, my technology has progressed very rapidly. During this period, my negative matter cannon has almost reached the actual combat level. There have been breakthroughs in tachyon shield technology, and new computers have been manufactured.
Success, after a few decades, I will definitely have the ability to defeat the Merian Civilized Fleet and implement your plan."
The ghost clan was silent again for a while. After a few minutes, it replied: "Very good, not bad. You did a good job. Well, I noticed a red dwarf star twenty light years away. It seemed that
There have been some unusual changes, do you know what these changes mean?"
"Have you noticed it too?" Xiao Yu said, "I am conducting research in this area. If there is any breakthrough, I will tell you."
"Well, I have an ominous premonition. This change seems to be caused by the arrival of some kind of malicious force. For your safety and for my last wish to be carried out, you must tell me after you have the research results.
I, must not make decisions without authorization, so as not to cause irreparable losses."
"Okay, I will follow your instructions carefully." Xiao Yu responded respectfully.
At this moment, more than twenty light-years away from Xiao Yu, this collection of numerous consciousnesses had already left the red dwarf star and was quietly waiting for something.
"According to calculations, at this time, the light from this star has been transmitted to the main civilization. Life or death depends on this."
"Yes, if even the main civilization can detect the strange changes in this star, then there is no reason why the previous generation of ghosts can't notice it. I'm worried that the previous generation of ghosts will use this to deduce that this is caused by us.
, will expose our arrival."
"It doesn't matter. It takes twenty years for light to pass through. During these twenty years, we have traveled dozens of light-years away and come to another direction. Even if the previous generation of ghosts can use this
No matter what we infer, it only knows that we have arrived, and due to our special hiding methods, it is impossible for it to find out our specific location."
"The only thing we need to worry about is whether it will become wary of the main civilization because of this, causing the main civilization to be unable to implement its own plan. But this communication method is the only way we can think of. We can only do this.
.The rest depends on our destiny and whether the main civilization has enough ability to solve the current crisis..."
"Yes. The situation this time is more dangerous than the last time we accidentally encountered the fleet of the Guardian Civilization and had to fight to the death to escape. Our main civilization has experienced too few things, and it is still too easy to trust others. He
I haven’t realized this truth yet. In this dark universe, no existence can be trusted except us. Any existence will only regard its own existence as its highest benefit. In this universe, there is no sacrifice.
Do you want to fulfill the civilized existence of others?"
"There is no point in discussing this. Who in this universe is not like this? Even we ourselves can develop ourselves by killing other civilizations? During these times, although we have no contact with the main civilization, we cannot communicate with the main civilization.
We need to make contact, but it can be foreseen that during this period of time, the main civilization will probably become extinct."
"All we have to do is wait slowly. If everything goes well, the main civilization will definitely find a way to contact us, so pay close attention to the movements of that weird star. Our vitality depends on the main civilization.
.Whenever you live, you live, and when you die, you die.”
After some debate, this ghost clan hidden in the corner of the universe became quiet again. They quietly concealed their whereabouts, relying on the ghost clan's unique methods to avoid being hunted by the previous generation of ghost clan, waiting in the dark night
With the dawn of dawn.
At this moment, Xiao Yu, who was next to the strange star, was still continuing to observe the red dwarf star. But what Xiao Yu couldn't figure out was that the strange change in the luminosity of the red dwarf star this time seemed to be accidental, which meant that it was only
It appeared once, and then disappeared. At least, during the period when Xiao Yu started observing, the red dwarf star was calm and quiet, completely showing the properties of an ordinary red dwarf star, without anything special.
So far, Xiao Yu has not realized that there is some kind of signal contained in these changes in brightness, but only studies it as some special phenomenon that he has not yet understood and mastered.
Looking at the calmed down red dwarf star, Xiao Yu thought angrily, "After taking care of the Molian civilization's fleet, I must go to the red dwarf star and take a look to see what's going on with it.
"
With this in mind, Xiao Yu completely gave up on research in this area. Instead, he handed over all the experimental data to the red dwarf research team of the Institute of Stellar Science, a subsidiary of the Central Academy of Sciences, and let them slowly start research. Xiao Yu
He himself once again focused his attention on technological development.
Time passed slowly, and about a month later, Xiao Yu received a message from the aging ghost clan.
"My junior, how is your research on the abnormal luminosity changes of that red dwarf star going? Are there any new discoveries?"
At the moment when he received the message, Xiao Yu had a little doubt in his heart, "I usually take the initiative to contact the senior ghost clan. It rarely contacts me actively, and it has never contacted me actively in recent times. But
For this red dwarf star, it contacted me twice in a row. Is this red dwarf star that important?"
With this thought in his mind, Xiao Yu still responded respectfully: "Senior, I have conducted some research on this aspect, but unfortunately, I have made no progress and found nothing."
"Well..." The aging ghost clan pondered for a moment and said, "The ominous premonition in my heart has become stronger. I have an intuition that the abnormal behavior of this red dwarf star will be the beginning of a disaster. And you, very soon
You may not be able to withstand this disaster and die. Therefore, you should step up your research on this aspect, and then tell me the results of your research, and I will find a way to deal with it."
Hearing what the aging ghost tribe said, Xiao Yu felt inexplicably nervous. During this period of time, Xiao Yu had already established trust in this aging ghost tribe, and subconsciously began to regard it as a human being.
One's own elders.
"Okay, senior, please rest assured that I will continue to conduct research in this area. If there are any research results, I will report to you as soon as possible."
"That's good, you can continue your research, I'm going to take a rest..." (To be continued, please search Piao Tian Literature, the novel is better and updated faster!
