Annihilation of the solar system

The staff hurriedly pushed the door open with a few pages of paper. Director Yin and Song Shi immediately greeted them, and Shen Manling also stopped what he was doing. Zhou Cheng picked up the pen lying on the paper and turned it Lift the cap of the pen.

"Professor Zhou, look at this result..." Director Yin handed over a piece of paper.

Zhou Cheng took the paper with the gravitational wave signal observation data printed on it, put it next to the paper he brought, and then started writing with a "swish". During the process, there was no abnormal sound in the conference room. Everyone's eyes were fixed on it. Focusing on the dancing pen in Zhou Cheng's hand, the anticipation in their eyes was like lottery players standing in front of the TV on lottery day.

Not long after, Zhou Cheng's black handwriting covered the entire paper. He turned the paper over, wrote two data in large letters on the back, and then circled them with a pen.

"The above is the mass and size of Oumuamua based on the wormhole size and opening and closing time inferred from gravitational waves. It is calculated by hand. It may not be accurate, but the order of magnitude is correct." Zhou Cheng said, While he closed the cap of the pen, the confident and somewhat aggressive look returned to his eyes.

Song Shi stared and confirmed the data repeatedly:

"Professor Zhou, according to your results, the actual size of Oumuamua is only 1/20 of what we observed four years ago! This..."

Director Yin's face was also full of doubts. Shen Manling piled up the information in front of her and moved it aside:

"This is entirely possible. We made speculations four years ago. The shape of 'Oumuamua we observed may not be its original appearance. It is entirely possible that in order to achieve the purpose of approaching the Earth to detect the Earth, it is entirely possible that it After reaching the Kuiper Belt and slowing down, we captured some natural meteorites to camouflage ourselves."

Some of the doubts on Director Yin's face were relieved, and Song Shi asked:

"Is it possible they sent something bigger through the wormhole?"

Everyone else heard what Song Shi meant. What he wanted to ask was whether it was possible that alien civilization had sent space battleships. After all, they were very close to the attack. Zhou Cheng shook his head:

"The wormhole we just detected is impossible. The opening and closing time of the wormhole and the size of the wormhole determine the upper limit of the mass and size of the objects it can pass. In other words, in the wormhole just now, it is possible to The only ones that came over were aircraft the size of the core of 'Oumuamua."

Everyone seemed to be relieved. A faint smile appeared on Shen Manling's lips:

"This also corroborates another of our previous inferences. Perhaps alien civilizations have not yet mastered the wormhole opening technology that can teleport fleets over. Otherwise, what we will face is not just the organic matter in the transfer orbit. A living thing."

"Either they haven't mastered it yet, or the cost of opening a large wormhole transport fleet is too high. They may not be able to bear it," Zhou Cheng added.

"Professor Zhou, what does 'may not be bearable' mean?" Song Shi asked.

"I have calculated that according to my theory, which is based on Liu Chaowen's model of particle structure below quarks, the energy required to open a wormhole will increase exponentially with the opening and closing time and size."

"What consequences will that bring?" Director Yin asked.

Zhou Cheng thought for a while:

"In the universe, the easiest source of energy is stars. Take our sun as an example. If you open a wormhole that can transport an aircraft carrier, the energy required is roughly equivalent to the total energy generated by the sun in ten years. The result To open a wormhole through which a fleet can pass is the same way."

Song Shi, who is mainly engaged in spacecraft research and development, and Director Yin, who has dealt with aerospace control for many years, do not quite understand Zhou Cheng's metaphor. For the sun, a star with a life span of tens of billions of years, losing ten years of energy output does not seem to be a problem. What a big deal. Shen Manling read the confusion in their eyes:

"This sounds easy, but in fact, there is a delicate balance between the outward radiation pressure generated by the fusion of the sun's core and the inward pressure of gravitational collapse. If energy of this order of magnitude is absorbed from the star in a short period of time, , even if the loss of energy conversion is not considered, it will have a great impact on the self-balance of the star.

If it were our sun, it would cause large-scale solar flares and sunspot bursts. This would have catastrophic effects on the planetary environment, including the Earth."

Several experts seem to agree on this issue and there is no longer any doubt.

Director Yin pointed to another circled data:

"What about this data?"

"This data shows that the location where the wormhole opens is about 4 light-years away from our solar system." Zhou Cheng replied.

Several experts nodded at the same time. This result changed the starting point of Oumuamua's arrival in the solar system from speculation to reality.

Zhou Cheng stood up slowly:

"My calculation logic uses the solutions generated by Liu Chaowen's theory. In addition to the above two solutions, there is another solution..."

He looked at the experts with some confusion, and pointed to the data on the paper marked with the location of Oumuamua:

"Is it possible for a compact celestial body to exist at this location?"

Everyone was surprised at the same time. After a while, Director Yin replied:

"Professor Zhou, according to the compact objects you mentioned, they are nothing more than white dwarfs, neutron stars and black holes. I think we can indeed rule out neutron stars and black holes easily. Because if their characteristics appear so close to us, I am afraid that we The earth's civilization has long ceased to exist.

It is known that the closest white dwarf star to the solar system is about 6 light years away. So far, no white dwarf has been found at the location you mentioned."

After Director Yin finished speaking, he asked doubtfully:

"Another solution is that there is a compact celestial body at this location?"

Zhou Cheng nodded:

"The solution generated based on Liu Chaowen's theory shows that the exit position of the wormhole must have a large space-time curvature as the space-time coordinate. It can be understood that if the golf ball does not have the flag next to the hole, the golfer will not know it at all. Where to hit the ball. And this curvature of space-time usually occurs near compact objects."

"You mean, 'Oumuamua emerged from the wormhole at that location not only to hide the gravitational wave signal, but also because there were necessary conditions for 'Oumuamua to pass through the wormhole?" Shen Manling looked at her husband.

"Yes." Zhou Cheng replied.

Song Shi on the side frowned deeply:

"The other party's act of destroying Europa proves that the other party has decided that hiding is no longer necessary. If a dense celestial body is a necessary condition for passing through a wormhole, the other party can open a wormhole near the sun, a dense celestial body, instead of continuing to choose It’s 4 light years away.”

Zhou Cheng looked at Song Shi:

"Einstein's general theory of relativity explains gravity as the curvature of space and time. If a wormhole is opened in the solar system, its gravitational effect will cause gravitational perturbation to the planet's orbit. If the orbit changes exceed a threshold, the earth will become a desert of life. .

I think, from the current situation, it seems that the other party wants to occupy the earth, rather than erase it."

"The logic of this explanation is valid." Song Shi looked at Shen Manling and Director Yin, "Do the two professors have a way to verify Professor Zhou's speculation?"

Shen Manling thought for a moment:

"Before the beginning of the crisis era, our sky survey project had observed that area of ​​airspace, where there was a dense interstellar dust cloud, which caused trouble for our traditional observation methods such as optical, infrared and gravitational lens observations."

Director Yin's face is still solemn:

"Professor Shen, I know the nebula you are talking about, and I have also studied the report of that sky survey project. At that time, an X-ray space telescope was also used to analyze the molecular cloud.

No abnormalities were found. If there is a white dwarf hidden behind that nebula, we can detect it through the Compton scattering effect caused by the x-rays it emits.

Actual observation results show that the density and spectrum of that nebula are a bit abnormal, but it is not as if there is a white dwarf hidden behind it."

Shen Manling's eyes suddenly lit up and she turned to look at Director Yin. Her naturally curly wavy hair rustled on the silk fabric on her shoulders:

"I remembered that there were more observation plans for that nebula. Because the accuracy of the X-ray space telescope at that time was not very suitable for observation at that distance, but the coming of the crisis era later made us put aside further observations. plan.

Now combined with Professor Zhou's speculation about compact objects, I also have a conjecture. If there is really a white dwarf star at that location, it must be formed by the collapse of a star with a similar mass to the sun at the end of its life. At the end of its life, it will expand into The red giant throws matter into the surrounding interstellar space, and when that matter cools, it forms nebulae.

If the nebula it formed happens to overlap in the direction facing us with the high-density region of the Oort Cloud in our own solar system, it will cause the complexity we see now.

In addition, if an alien civilization uses a white dwarf star to open a wormhole, it is likely to absorb the energy of the white dwarf star. If this guess is true, the typical characteristics of the white dwarf star will be very different from the white dwarf stars we are familiar with, which may also cause our It's very difficult to detect through conventional means."

Director Yin and Song Shi looked at each other, and their discussion gradually turned from doubts to sighs.

Zhou Cheng looked at his wife who made an impassioned speech, and felt a warm current in his heart.

Song Shi asked:

"Director Yin, does your space control center have a way to mobilize resources to organize observations immediately?"

Director Yin nodded:

"Our most powerful observation equipment now is Gaoming and Webb. Together with Xia Lan and Wei Xu, they are all above the ecliptic plane of the solar system, which is very convenient for observation. I will notify them immediately!"
