In the early nineteenth century, the British physicist Thomas Young published a scientific paper called "Experiments and Calculations Related to Physical Optics", which mainly described a set of experiments to prove the wave and particle properties of photons in physical optics. ”

"It emits a little light source in the dark, and the light source passes through a slit, so that a separate band of light with a continuous attenuation from the middle to the sides can be obtained on the detection screen behind the slit. ”

Lird tried to express the content of this physics experiment in rigorous language, and at this time, Lird kept complaining in his heart why he didn't know more about physics in the first place, otherwise these things would not be so difficult for him.

Qianrou listened quietly to Liard's explanation, obviously she was not much more knowledgeable about modern physics than Liard, and she did not know much about what Lird was saying, which made Lird feel a lot more relieved.

Lird then continues: "You may not be surprised by this phenomenon, because it often happens in our daily lives, but have you never seen the pattern of light that forms when a beam of light passes through two slits?"

Qian Rou said softly, "Aren't they two rays of light?"

"Of course not. Lird denied, and at the same time felt a lot more at ease.

"While I can't show you the details of the experiment here, I can tell you responsibly that when the light source passes through two slits, it forms a beam interference fringe that gradually diffuses and decays from the middle to the sides on the detection screen. ”

"Interference streaks?" Qianrou narrowed her eyes, as if trying to imagine the scene that Lird had described.

"It's a strange phenomenon, isn't it!" Lird seemed to give Qianrou time to digest, but Qianrou didn't want to wait too long, so she urged Lird to continue.

Lird said: "From this simple experiment can prove that light exists in a kind of light wave nature, and at the time of passing through the slit, the broadcasts interfere with each other, thus forming a superimposed gradient attenuation grating light pattern. ”

Qianrou doesn't have too intuitive feelings about this light-wave theory, but fortunately, the current experimental process is not too complicated, and it can be fully understood. At this moment, Lird continued: "After that, the experiment continues. The number of slits through which the speed of light passes increases to four. According to the ordinary people's thinking, the interference fringes formed on the projection screen should be increased by some multiple, but this is not the case. ”

"Grating interference fringes are decreasing, and the number is half of the previous number!"

Although she did not witness it with her own eyes, Qianrou was also shocked by the conclusions of these experiments, and her eyes showed great interest, looking forward to Lird's further explanation.

Lird swallowed and said, "The reason for this phenomenon is that the number of slits increases, which leads to a more complex phenomenon of mutual interference of light waves through the slits, and this phenomenon further indicates the interference phenomenon caused by the superposition of light waves." ”

Qianrou nodded and said, "So it's called the 'Double-slit Interference Experiment'?" Lird nodded, and Qianrou said, "It's an interesting scientific phenomenon, but what does this have to do with the future of our tribe?"

Lird said: "Don't worry, this simple experimental demonstration can only be regarded as an introduction, and the real plan has just begun." ”

Lird licked his lips and said, "After the double-slit interference experiment was certified by the world, the rest of the scientists also carried out further verification experiments. ”

"Before further experiments begin, I would like to point out that in the more than 100 years since the double-slit experiment, scientists have begun to determine the form or nature of light, which is defined as an energy that exists in the form of continuous and independent units, that is, light is composed of light particles, but this statement cannot be accepted by the academic community, because this part of the theory conflicts with the bimodal experiment I mentioned earlier, and people have begun to argue between light waves and light particle theory. ”

"Light particles—" Qianrou muttered as she repeated Liard's words, her palms unconsciously spreading out and clenching, as if she wanted to hold the light particles in the air into her hands.

"Until nearly 40 years ago, the famous physicist Albert Einstein derived the basic property of microscopic particles through his research 'wave-particle duality', which made people understand that light waves actually have the dual properties of waves and particles at the same time through the light quantum interpretation of the photoelectric effect. ”

Qianrou blinked her eyes and said, "What you said already sounds complicated. Obviously, the content here began to confuse Qianrou's thoughts, in fact, not only Qianrou, but also Lird's theory of this step was really half-understood, and these contents were completely what the other party told him during the phone call with Gerald.

Unlike Gerald's previous rhetoric of using the timeline of four-dimensional space to illustrate the theory of multiverses, this time Gerald explained the possibility of the multiverse from the other side of the theory of the basis of reality.

For Qianrou, who was a little confused, Lird was a little happy and a little nervous.

Fortunately, his theoretical basis will not be nakedly punctured by Qianrou for the time being, on the other hand, he is also worried that Qianrou will grasp one of the points of this set of theories and keep asking himself stubbornly, then he will definitely not be able to parry, to know whether all this he tells is rigorous or not can not be guaranteed.

Thinking of this, Lird hurriedly continued: "After unifying the definition of light form, scientists are improving the double-slit experiment again. ”

In a laboratory several kilometers underground, in absolute darkness, the scientists replaced the experimental light source with a particle emitter, which they controlled so that it projected only one photon at a time, and replaced the previous detection screen with a light sensor to accurately receive the photons emitted by the particle emitter. ”

Qianrou frowned and said, "Are they trying to rule out the interference of light waves in the experiment?"

Lird nodded: "That's right, this experiment is to study the motion properties of a single photon, but the results of the experiment are extremely unexpected by scientists." ”

"The results received by the light sensor are very chaotic, all the photons released by the particle emitter through the slit are not stable and completely amorphous, and after a large number of photons are projected, the map received by the light sensor is almost the same as the double-slit interference experiment more than 100 years ago. ”

Qianrou gasped when she heard this, and her reaction was like that of those extremely surprised scientists, and she was also deeply surprised by this result.

"Are you saying that this so-called photon has no probability of landing at all, but it can exhibit some special properties, as if it has been interfered with by other substances... Right?"

Lird nodded again when he heard this, and at the same time he admired his softness more and more, although he did not understand these advanced physical knowledge, but he could make a more accurate judgment through the logical reasoning between the two, this meticulous mind was by no means able to achieve himself, to know that he had expounded this point of things, Gerald began to talk to himself several times before rote memorization.

Qian Rou thought for a moment and then changed the topic back again, "Even so, what do these things have to do with the safety of our clan?"

Lird didn't answer Qianrou, but just looked at Qianrou and said, "What do you think is interfering with the irregular movement of those photons?"

Qianrou thought for a moment and said, "Maybe it's the magnetic field in the earth, maybe it's some invisible substance..."

"Have you ever thought that it is a photon from another dimension that influences the movement of this photon?" said Liald compulsively.

"Photons from another dimension?" Qianrou said in surprise, her eyes full of incredulity.

At this point, Lird did not continue to talk about the theoretical knowledge that he did not understand, and Lird said: "According to the above experiments, and through some inferences and conjectures of physics, maybe in this world... No, this universe is not right!"

"Maybe there is another cosmic space outside of this space we are in, and there is our hope!"

[*Note: The theory of multiple universes was proposed by the American physicist Hugh Evert in the spring of 1957, and its application is advanced in this book.]

In addition, the important concept of multi-universe theory is based on the "Wheeler bubble", that is, "quantum bubble" and "space-time bubble", which was proposed by the American physicist John Archibald Wheeler in 1955, which is inconsistent with the year in which Lird is now in 1942, so this theoretical basis is not adopted. 】

...

When Lird said all this, Lird and Qianrou fell into a long and terrible silence.

Qianrou was always silent, her eyes were a little trance-like, while Lird stared at Qianrou quite nervously, staring at her with some indaguity.

After a long time, Qian Rouyu slowly spoke: "Do you want to say, let us migrate to another universe?"

"That's right. Lird nodded, glad that Qianrou understood what he meant.

I don't want Qianrou to have the fierce reaction that Lird had expected, and of course she didn't agree with what he said, Qianrou's performance was more like a sense of indifferent abandonment, and this look made Liarde feel even more bad.

After a while, Qianrou smiled lightly and said, "I can feel your kindness, but as for your plan... I can't put it into words for a while, but all in all, it makes me feel very... Ridiculous. ”

Lird snapped, "I know it may sound ridiculous, but..."

Qianrou stretched out her hand to stop Hugo, who was eager to explain, and said: "Whether or not what you are telling is fully substantiated, whether there is a multi-universe space for you, can you not achieve what kind of danger your whole tribe wants to send our whole tribe to that unknown world? Do you know what dangers there are in that place? Can we survive there? I dare say that that kind of place may be a hundred times more dangerous than the Sahara sofa, and I still feel that Churchill's cigar and Hitler's mustache are more intimate than them." ”

"But neither a cigar nor a mustache are things you can't face, can you?" exclaimed Lird at the moment, too, anxiously.

"You have to see some clearly! you are no less dangerous now than going to another cosmic world!" said Lird further.

Looking at the indignant Lird in front of her, at this moment Qianrou realized that the crazy idea in her eyes was Lird's most serious plan.

Lird said: "You have been choosing to live in silence and low-key for more than 10,000 years, and it seems that you have chosen to be ordinary without any quarrel with the world, but is this really the case? Are you really choosing to be ordinary? No, you have chosen another path of perseverance and burden!"

"If Atlantis really gave up everything, then they would settle down in one place, start a new life, start a new culture. Maybe they will come out of the glory of the past, but at the same time they will come out of the shadows of the past, they may forget their language, but they will also get to know the world and integrate into more cultures. Maybe you could have done more, maybe with your participation, the world wouldn't be like this, but you didn't. ”

"I don't know the root cause of what you do, but I can guess that what you have to keep is nothing more than a secret, a secret that is unacceptable to other humans, and what you have to protect is that [power]. ”

Hearing Liard's words, a fierce look flashed in Qianrou's eyes, but this expression quickly turned into complicated sadness and helplessness.

Lird is fearless about everything at the moment, all he has to do is vent and express.

"I have seen the power that can reach such a terrible level with only a vestige of my father's body, and he has also wiped out a military town of hundreds of men from the world, and this force is completely unforeseeable, and perhaps it is not worth mentioning compared to the nuclear weapons that mankind is researching, and if this [power] is known to the world, it will inevitably bring even more crazy changes to the world in the future, and perhaps then the end of the human world will come. ”

After some excited words, Lird calmed down and said slowly: "I understand the heavy burden that the Atlantean remnants have borne for ten thousand years, and thank you for all you have done for humanity. For 10,000 years, the remnants of Atlantis have dedicated their lives to this responsibility, sacrificing their youth, dreams and even their lives, but this responsibility and mission will continue until the future, which is not only a mission and responsibility, but also a curse. ”

"In a fairy tale called 'Alice's Adventures in the Looking Glass,' a character named the Red Queen says: 'In this kingdom, you have to keep running to keep you in place.'" This is also true for the Atlantean remnants. You have not changed for thousands of years, and now you must try to change, otherwise all that awaits you is destruction. ”
