Paranormal incident investigation notes

"A reliable enough positioning device?"

He Weili looked at Lu Ming with some confusion: "The mobile phone in your hand is reliable enough. Except for a few places, as long as you are on the earth, you can be located."

"That's totally not enough."

Lu Ming shook his head: "What I want is the kind of positioning device that is absolutely reliable and can locate me no matter where I am, whether it is under the sea or underground, even thousands of meters deep underground."

Zhang Dingshan said: "You should be very clear that our human technology cannot do it."

Lu Ming did know this very well.

Existing positioning technology, whether base station positioning or satellite positioning, relies on the transmission of electromagnetic waves. From low to high frequency, electromagnetic waves are radio waves - that is, radio waves used for communication, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays.

However, the penetrating ability of electromagnetic waves of all frequencies is not very strong. It can even be said that all radio communication technologies will completely fail when faced with obstacles that are only about a hundred meters thick, such as rocks, soil or water.

This obviously does not meet Lu Ming's requirements.

But what he was asking about was not human technology.

Division 13 of your Planetary Security Bureau is an agency that specializes in dealing with "supernatural forces." You should have experienced and seen many super technologies.

Have you not studied these alien technologies or creations? Are there any results? Or is there simply some device obtained from aliens that can meet this requirement?

Lu Ming looked at Zhang Dingshan, and he knew that Zhang Dingshan understood what he meant.

Zhang Dingshan thought for a moment and said, "Tell me what you think."

Lu Ming said: "My idea is very simple."

He gritted his teeth: "If there is such a device, I will take it to that metal room! After that, you can use this device to locate my position!"

Because Lu Ming had already entered the metal room - this metal room was most likely the residence of the mountain god, a transfer station that was speculated to exist on the earth - Lu Ming's location was naturally located. The location of the transfer station was located.

What to do after that is simple. It is nothing more than mobilizing men, horses and equipment there and entering the transfer station on a large scale. At that time, whether to destroy or control depends on the will of mankind.

For the current technological level of human civilization, this plan has a very huge loophole. That is, the electromagnetic wave signals used by humans for positioning are most likely unable to be transmitted to the outside world from the transfer station!

Not to mention that there may be signal shielding at the transfer station. Even if it is not, who can be sure that the location of the transfer station is on the surface?

Is it possible it's under the sea? Is it possible that it's at the base of the mountain? Or underground?

Even in tunnels, human positioning and communication devices will face failure problems, let alone underground, underwater, or even hundreds of meters, thousands of meters, or even deeper into the mountains!

Any positioning device will fail.

Therefore, it is necessary to have a "sufficiently reliable" positioning device as Lu Ming said, for this plan to be meaningful.

"Previously, the images left by the core members of Organization You can bring it in!”

Both Zhang Dingshan and He Wei's expressions became serious.

He Wei first said: "So, Lu Ming, have you ever thought about a problem - even if this device exists, you have successfully brought it into the transfer station, and we have successfully located your location, but if, The location we located...is somewhere we can't reach, so what should we do?"

Even the Mariana Trench can be reached by submersibles built by humans. Even the moon can be reached by spacecraft made by humans.

But if the location is located further than the moon - from a cosmic scale, this can also be considered to be near the earth, or it may be 10 kilometers, 20 kilometers, 100 kilometers or even deeper underground. what to do?

With the current technology of mankind, it is simply impossible to complete such a deep rescue. At that time, even if the location of Lu Ming and the transfer station was successfully located, all he could do was watch Lu Ming wait for death.

This is a possibility that must be considered.

Lu Ming gritted his teeth: "I know this possibility. But I still want to give it a try."

He Wei was startled.

She felt like she didn't understand Lu Ming anymore.

Lu Ming is just an ordinary person. Where did he... get such courage?

Even if it were me, I wouldn't be able to guarantee that I would make such a decision when faced with this situation.

Lu Ming didn't explain too much, but looked at Zhang Dingshan and He Wei firmly.

Zhang Dingshan said solemnly: "Lu Ming, are you sure?"

Lu Ming nodded firmly: "I'm sure."

Zhang Dingshan looked at Lu Ming's eyes seriously for a long time, and then said slowly: "I'm not sure if there is an absolutely reliable positioning device like you want. I need to call some experts to study it."

"good."

Lu Ming stayed here for the rest of the time.

Although it is only a temporary landing point, all facilities are available here. The temporary residence not only has electricity, but also has air conditioning, hot water supply, and even the Internet.

Meals are provided every day by dedicated personnel. After eating and drinking, Lu Ming can even walk around the landing point and take in the scenery accompanied by security personnel.

Three days passed like this. Three days later, Lu Ming received a call from Zhang Dingshan at the headquarters.

"What you need for an absolutely reliable positioning device, we have it."

Lu Ming felt a little excited. But after being excited, he was full of doubts.

With his knowledge, he could not imagine what principle or mechanism would be used to create an "absolutely reliable" device that could send information no matter where it was.

"During a certain investigation, we seized a device that we don't know where it came from. We are not sure the specific function of the device, and we did not find any impact on the surrounding environment during the experiment. We only know that when the device is triggered, After the device is installed, a huge amount of neutrinos will be produced. We name it a neutrino bomb.

We plan to use this neutrino bomb as your positioning device. "

Neutrino?

Lu Ming was startled for a moment, then reacted immediately.

If this unknown device named "neutrino bomb" can really produce a large enough number of neutrinos, then it can indeed be used to achieve "absolutely reliable" positioning!

This is because neutrinos have extremely small mass and are electrically neutral. It does not participate in electromagnetic interaction and strong interaction, and is only affected by gravity and weak interaction. But at the microscopic particle level, gravity and the weak force are extremely small and have almost no impact on it.

This means that neutrinos are extremely penetrating. It can even penetrate the entire earth and the entire sun without any hindrance, or it can penetrate tens of thousands of light-years from the center of the Milky Way, penetrate the barriers of countless stars and dust clouds, and reach the earth smoothly all the way.

According to scientific statistics, on average, approximately 65 billion neutrinos pass through every square centimeter of area every second. On an average day, the body of any adult on Earth will be penetrated by a total of about 400 billion neutrinos.

But the result is that so many neutrinos will not have any impact on the human body or the environment. Because they will penetrate everything almost without any hindrance and fly out from the other side of the earth.

Theoretically speaking, no matter where the mountain god's residence, that is, the transfer station, is located, even if it is located in the core of the earth and is separated from the surface by thousands of kilometers of rock formations, or what kind of signal shielding is done, it is impossible to block the passage of neutrinos. through.

If this device named "neutrino bomb" detonates in the mountain god's residence, a huge amount of neutrino radiation will inevitably penetrate from its interior.

And... with the current technology of mankind, the detection of neutrinos can be completed.

Neutrino telescopes built hundreds or even thousands of meters underground can rely on their large enough size to maximize the interception rate of neutrinos.

Even if every square centimeter averages one second, only one out of a million billions of neutrinos will be intercepted by a neutrino telescope, as long as the number of neutrinos released by this neutrino bomb is enough. , as long as the size of the neutrino telescope is large enough, there will always be a few neutrinos observed in the "neutrino radiation burst" caused by the neutrino bomb.

Through the energy of neutrinos, it can be determined whether the detected neutrinos were emitted by this "neutrino radiation burst". Through the incident angle of the neutrino, its flight direction can be inferred.

Because neutrinos will not be reflected or scattered during flight, then, on the premise of knowing the orientation of the neutrino telescope and the incident angle of the neutrino, and inverting the flight direction, it is easy to calculate the neutrino The direction of the radiation source is deduced.

But this is not enough. The reason is simple. It is assumed that through calculations, it is confirmed that the neutrino radiation source is to the west of the neutrino telescope, but the distance cannot be determined.

Is it one kilometer to the west, or ten kilometers, or ten thousand kilometers?

Not knowing the distance, only knowing the direction, is still meaningless.

This requires at least two neutrino telescopes located at different locations to observe this at the same time, measure two directions, and draw two straight lines. Then, if these two straight lines are extended, their intersection must be the location of the neutrino radiation source.

Because the neutrino bomb has been brought into the Mountain God's residence by Lu Ming, then the location of the neutrino radiation source is the location of the Mountain God's residence.
