"When?" Zhang Dada's words attracted the attention of everyone present.

"The information I decoded from those aliens before only has three coordinates, and each of these three coordinates corresponds to a time, and the time is only accurate to the sky."

"Well, I've read your previous report many times," Qin Yi nodded, he knew that Zhang Dada still had something to say.

"Because the time corresponding to these three coordinates is all in the past, I unconsciously ignore them, but when you think about it, they should be as inseparable as the coordinates." "I'm not sure if the information revealed by those alien texts indicates what happened at the coordinates of the corresponding time or something else, but I now clearly realize that as a limited few pieces of information, I shouldn't continue to ignore them." ”

"Time in the past? Now that time has passed, what does this message mean for us? A senior government member asked.

"I think Professor Zhang's analysis has a certain possibility," Qin Yi said suddenly, "As an alien species far beyond the civilization of the earth, they must have completely crushed our civilization on the earth in terms of technology and culture." Since we have deciphered the information of coordinates and time in the words they left behind, then the information of coordinates and time must have its value, because the development of civilization is a process of removing the chaff from the chaff. ”

"Yes, yes. Writing and language are created in response to the needs of culture, and culture can also be expressed and disseminated in the corresponding language. The more civilization develops, the more refined the words and languages become, and the more explicit the meaning of things they express, and any piece of information in the alien text is a very crucial clue. Alas, I only thought it was a past time, and I didn't pay enough attention to it, and now I think about it. Zhang Dada sighed as he spoke, looking remorseful.

"Professor Zhang, in that case, do we have to go to the coordinate position corresponding to that time?" Someone in the top echelons of government asked.

"Now it seems that I'm afraid so," Zhang Dada nodded, his expression a little solemn, "This operation is almost fruitless, and the problem should be here." ”

"Isn't that clue equivalent to walking into a dead end, how can we travel back in time to the past," someone said in one sentence.

"Alas," Zhang Dada sighed again, acquiescing to the high-level opinion.

"Not necessarily," Qin Yi said these three words again.

"How?" This time, everyone's eyes shifted to him.

"Do you know about the Philadelphia Experiment?" Qin Yi looked at everyone and asked them.

Seeing that everyone was at a loss, he began to tell about it.

"The Philadelphia Experiment is also known as Project Philadelphia, also known as Project Rainbow. In October 1943, the U.S. Navy conducted a classified experiment in Philadelphia to create an artificial magnetic field, which successfully plunged a destroyer, the USS Eldridge, and its entire crew into another space. During the experiment, the experimenter activates pulsed and non-pulsed devices to create a very large magnetic field around the vessel. Then the entire ship was enveloped in a cloud of light, and the ship and crew began to disappear from view. ”

When the experiment was terminated, it was discovered that the ship had been moved to Norfolk Harbor, 479 kilometers away. And after that, some of the crew members of the Eldridge still had experimental reactions, and they suddenly disappeared and reappeared at home, on the street, and even in bars and restaurants, much to the surprise of many witnesses. ”

"Mi Guo has also done such an experiment?!" Zhang Dada was a little surprised.

"Yes," Qin Yi nodded, and continued to describe the information about the "Philadelphia Experiment".

The main person involved in the experiment committed suicide a few days after the experiment, and before he died, he said that the experiment was related to Einstein's theory of relativity. Dr. Gisop, one of the participants in this experiment, made one of his points that a strong magnetic cloud is capable of rearranging the molecular structure of humans and matter into another space-time. ”

"The Philadelphia experiment is scientifically significant, not only confirming the existence of another space in nature, but also showing the feasibility of temporarily committing humans and equipment to another dimension. Although the US Navy has already covered up the truth, there are still many clues revealed, such as when it was in World War II, the US Bureau was willing to take a brand-new destroyer urgently needed for the war to do a 'disappear' experiment, instead of taking a broken ship first and trying it unsuccessfully. ”

"Academician Qin," the senior management of Chongming has great respect for this academician of the Chinese Academy of Sciences, because these academicians represented by Qin Yi are the highest level of guarantee in science and technology in China, and the title of academician is also a lifelong honor. "Does this Philadelphia experiment have anything to do with traveling through time?"

"The relationship between them is that of space and time." Qin Yi explained, "In philosophy, the relationship between space and time expresses the evolutionary order of things. Time and space are absolute concepts, fundamental properties of existence, and the values we observe and measure them are relative to the frame of reference. The connotation of 'time' is infinite and eternal, and the extension is the measurement of each order of time or each finite period of time. The connotation of 'space' is unbounded and eternal, and the extension is the measurement of the relative position or size of each finite part of space. In the special theory of relativity, the speed of light is the common ruler for measuring time and space, and the changes in time and space show the law of dependence on this ruler, that is, follow the Lorentz transformation. Therefore, the measured values of time and space are relative to specific inertial frames, such as simultaneity is not absolute in measurement, and two events occur at the same time relative to a certain reference frame, and may not occur at the same time relative to another reference frame; Lengths and periods of time are also not absolute in measurement, with a moving ruler becoming shorter relative to a resting ruler and a moving bell slower relative to a stationary clock. ”

Although Qin Yi has tried his best to describe it in easy-to-understand language, the theoretical knowledge in it still sounds like a book from heaven to the layman.

From the expressions of the people around him, Qin Yi knew that everyone still didn't understand the meaning of the "Philadelphia Experiment", he thought about it and concluded, "We can understand it this way, the other space that the 'Philadelphia Experiment' sent to the Eldridge and the crew of the ship is still the earth, just like the ship and people appeared in Norfolk Harbor hundreds of kilometers away as a result, the only difference between the space after teleportation and the space before the experiment is the difference in time." ”

"So the 'Philadelphia Experiment' is actually an experiment that travels through time?" Zhang Dada finally understood, and he was a little shocked by the news, because this situation should only exist in science fiction movies in his consciousness.

"Yes, we don't know if it's going back in time or going to the future, because all the records of the 'Philadelphia Experiment' are classified as top secret documents."

"Can we then go to the coordinates of that point in time as indicated by the alien text?" Zhang Dada looked at Qin Yi as if he had seen hope, his eyes lit up.

Qin Yi suddenly lowered his head and thought about it, he said again, "At present, we don't have this technology in our hands, and we don't know what stage of Mi Guo's research in this area has reached, of course, the 'Philadelphia Experiment' happened in 1943, so more than half a century should be enough time for them to take their technology to the next level." If we want to continue to investigate the information deciphered from the alien text, we must join hands with the United States. “

"Do you join hands with the people of the United States? The technology is in their hands, will they leave us alone after we tell them the deciphered information? Someone raised his concerns, and his words were echoed by many people present.

"There is this possibility," Qin Yi did not deny his point of view, but as a scientist, these things are no longer within the scope of his concern, "This is like a game, although the cards in our hands are not as big as the other party, but it does not mean that we will definitely lose, the result depends on the skill of the card holder and the play on the spot." After I return to Changping, I will report the relevant situation, and I believe that the chairman should have his own intentions in his heart. ”

The others nodded one after another, and Qin Yi's words were also telling everyone that how to promote this matter next is no longer something that these people present can decide, and it should be up to the leaders of Huaguo to take care of it.

"Ladies and gentlemen," said a senior member of Chongming, "regarding our conversation here today, please all of you must follow the discipline of the organization and keep your mouth shut. ”

"Mayor Han, I heard that a Jepsy was rescued in Piramidden on Spitsbergen during this operation?" After Qin Yi waited for the high-level to finish speaking, he suddenly asked about this matter.

"Yes, the Gipsy survivor's name is Alexei Strakhov, and he is the one who is stationed in Piramidan on behalf of the Gipsy government." Mayor Han nodded, and the information about the Jeplos had already been handed to his desk on the way back to Chongming on the Snow Dragon.

"How's he doing? What is this person going to do next? ”

"Recovering well." Mayor Han said, "We will put him here for the time being, and we will not send him back to Gipros in the short term, because he has been following our scientific expedition team since Piramidon was rescued, and if we send him back to Jipros, it will be equivalent to telling the Gipros government about our scientific expedition operations." ”

"Your consideration is very thoughtful," Qin Yi put his mind at ease, "I will return to Changping as soon as possible, but before I go back, I still want to talk to Professor Zhang Dada alone." ”

"Okay," Mayor Han nodded, and left the conference room with the others, leaving the place inside to Qin Yi and Zhang Dada.
