280,000 kilometers away from the Earth, in the dark space, a space-time distortion area with a diameter of only 23 meters is quietly resting there, following the Earth around the sun, maintaining a relative distance from the Earth.

23 meters, this value is so inconspicuous in the vast space of space.

At the same time, this space-time distortion region is not between the Sun and the Earth, but maintains an oblique angle to ensure that the situation on the ground of the Earth's hemisphere during the day can be observed through high-precision cameras, and does not block the light that affects the transmission of the Sun to the Earth.

In the state of curvature, or in the state of distorting space-time and deliberately hidden, can other electromagnetic waves, rays, and radar scans be found in external observations, except for gravitational waves?

This is a question that has been discussed several times by human scientists.

In the end, the answer is no.

Because in actual reality, light should not be said to travel in a straight line, but rather to be said to be traveling along a space-time trajectory.

At that time, Einstein's general theory of relativity was verified by using solar eclipses to verify the effect of space-time curvature caused by the sun on the propagation of light.

One is to take pictures of the starlight passing by the sun with the help of a solar eclipse, and the other is to photograph the normal starlight without the sun on the other side of the orbit when the earth rotates, and finally by calculating the difference in the coordinates of the two stars, this verifies the correctness of the general theory of relativity.

If it is not discovered in advance, and there is no data comparison, then when there is an item that is hidden by distorted space-time, except for gravitational waves, other radar scans, light detection, etc., will not be able to find the anomaly here at all.

Because in your data, that's what it is.

Even if there is a data comparison, if the gravitational space-time technology is developed enough to control the space-time distortion trajectory relatively finely, it can be hidden.

Figuratively, you are standing under the sun, and the sunlight is shining on you, but then the time and space around you are distorted.

Light travels along the trajectory of space-time, bypassing you and coming behind you, and then propagating according to the angle of light propagation calculated assuming that you do not exist.

In this way, the person standing behind you can see the sun and will not notice anything abnormal, and even if he walks forward, he will not bump into you, because not only does it travel along the trajectory of space-time, but objects also have to be based on space-time.

Hidden by the distortion of space-time, you are like living in a space-time bubble, as long as you are not actively exposed, the outside world will not be able to detect you or touch you except for the traces of gravitational waves.

"Lu Lu, the latest news, the Human Detection Joint Department has completed the search for light from the sun to the earth, and no traces of deflection or distortion have been found."

More than a month has passed since the discovery of remotely sensed electromagnetic waves, and the Earth monitoring system has not detected new remotely sensed electromagnetic wave signals, and the search for sunlight has not found traces of distortion or deflection.

"I know."

Lu Yi nodded, got up, took the car keys, and turned around and walked out: "Let's go to CUHK together, my sister will enter school today." ”

It's September now, and it's time for new students to enroll, and Princess Lu Ying has also graduated from high school and passed the college entrance examination.

already has a son who is busy all year round and has little time to go home, this time Lu's mother forcibly suppressed Lu Ying's little princess's desire to follow in her brother's footsteps and apply for the physics major.

However, the little princess Lu Ying is not a vegetarian, knowing that there are really aliens in the universe, she has a strong interest in interstellar alien civilizations, with the difference in knowledge and insight, she successfully fooled Lu's mother to apply for the interstellar major just opened this year.

This is a new major opened this year, focusing on the social form of alien civilizations, civilization systems, civilization social psychology, and involving some of the core technologies of civilization.

To put it simply, this is the cultivation of a think tank talent, responsible for providing professional advice when humans and extraterrestrial civilizations clash in the future, preventing human civilization information from being harvested, and how to harvest alien civilization information.

After all, being beaten and not fighting back is either a history of civilization development or a history of war, and the human hierarchy is always thinking about waiting for human science and technology to develop further and go to the interstellar to harvest information about other civilizations.

"Lu Lu, let's give up for the time being, if we want to continue, we will use the resources of the Tomorrow Group." Zhang Qing followed in Lu Yi's footsteps and sighed and proposed.

"There are too few resources that Tomorrow Group can mobilize." Lu Yi sent a message to Professor Lin, shaking his head to reject Zhang Qing's proposal.

"But if you continue like this, you will offend many scientists of mankind!"

Zhang Qing persuaded in a hurry, because of Lu Yi's proposal and application, most of the resources and productivity of human civilization are now invested in the construction of a super-large gravitational wave observatory, as well as the search and prevention of this unknown fourth-level civilization.

No one can have an opinion on the construction of a super-large gravitational-wave observatory, after all, this is a strategic equipment of civilization.

However, the search for the unknown fourth-level civilization has been unsuccessful for more than a month, the light from the sun to the earth has not been distorted and deflected, and the human warships and probes have covered the space of 200,000 kilometers on the earth without finding traces, and there have been different voices within the human civilization.

After all, according to the original predetermined scientific research plan, these resources and productivity were to be allocated to scientific research projects one by one, but now because of Lu Yi's stubborn proposal and application, these resource allocations have been reduced.

Many people think that the fourth-level civilization looks down on human civilization and has left, so there is no need to continue to spend a lot of resources to search for and build semi-permeable membrane defense.

That is, the prestige that Lu Yi has established in the past few years is deeply rooted in the hearts of the people, and these different voices dare not be directly revealed.

But if it continues, these voices will inevitably be unsuppressed, and then Lu Yi will really offend most of the scientific groups of human civilization.

What's even more serious is that if so many resources are spent, and it is finally determined that the unknown fourth-level civilization has indeed left, then the prestige that Lu Yi has built up in the past few years will be in vain.

At that time, there will be fewer people to send charcoal in the snow, and more people will fall into the well.

"Do you see the leaders have said they have any objections?

As the managers of civilization and the group of scientists who can influence the opinions of managers, we must face the matter of the survival of civilization with the utmost caution before ensuring that the crisis is resolved. ”

Lu Yi shook his head disdainfully: "If the resources are gone, then they can be reproduced, and the productivity will be occupied, and it will not be without it in the future."

But if civilization is gone, then there is nothing.

At this time, people who still care about their personal interests are just a group of short-sighted mediocrity, and since they are mediocre, they will be offended. ”

Lu Yi was still a little worried when he saw Zhang Qing's expression, stretched out his hand to take her hand, and said with a smile: "Don't worry about me, this chief scientist is really going to be driven down, isn't that a good thing, then there will be more time to accompany you shopping, cooking, doing housework or something." ”

"I'm embarrassed to say that I haven't seen you mopping the land at home for a month." Hearing Lu Yi say this, Zhang Qing finally let go of the worries in her heart, and glanced at the grinning Lu Yi angrily.

"Okay, okay, after sending my sister to school, I'll mop the floor when I come back tonight." Lu Yi assured repeatedly.

"Lu Lu, did you say that the fourth-level civilization really didn't leave?"

"Since the other party has discovered us, they will definitely not let it go."

Lu Yi, who lives in a forced information life, understands that human beings are definitely a special civilization, raised his head and looked at a blue sky, and affirmed: "I have a hunch that he is watching us from a corner near the earth, waiting for the opportunity to obtain information about our civilization......"
