Later, the woman became pregnant, and the man lifted his pants and refused to admit it, which led to the later tragedy.

When the girl jumped off the building, she was wearing a school uniform on her upper body and jeans on her lower body, because she was on the ground with her face, when the school teachers and classmates arrived at the scene, they saw that her face was covered with blood, and her mouth was still bubbling blood, and she was not dead, but she was already dying.

As for the man, I heard that he died in a car accident later, and when he was found, his hands were stuck in his neck, and his tongue was sticking out more than ten centimeters, which even the doctor wondered.

And the cause of death is also very special, it turned out to be suffocation.

Gao Guofeng's purpose in saying this was to tell me that the senior brother probably really saw the soul of the girl who jumped off the building last night, but he still insisted that this soul came from another dimension, which is the so-called "different dimension".

For the next half month, Gao Guofeng took me to the school library and a bookstore more than ten miles away from the school.

At first, we checked the "alien space", but after a check, we found that the "alien dimension" is actually a parallel universe called in science.

I also made a dozen pages of notes at the time:

The so-called parallel universe refers to the parallel force universe, which is the opposite of the gravitational universe.

The parallel forces of parallel universes produce a pure elementary particle universe, and the gravitational forces of the opposite gravitational universe produce a pure planetary universe. The parallel force universe of the parallel universe and the opposite gravitational planet universe form the multiverse.

Among these universes, there are universes that are born under the same conditions of interaction forces as our universe, there may be planets that are the same as the planets inhabited by humans, or planets with the same history, and there may be universes with unknown interaction forces that are completely different from human beings.

In these universes of different interacting forces, things develop with different outcomes.

The parallel universe of parallel forces is the opposite of the gravitational planetary universe of human beings, and the parallel forces neither coincide nor intersect, which can be described as "well water does not interfere with river water", resulting in a pure elementary particle universe, which is just opposite to the pure planet of human gravitational universe.

Some scholars use the metaphor of parallel universes when describing them, they may be in the same space system, and parallel forces move in parallel, like two trains speeding on the same railway line; They may be in the same time system, but the spatial system is different, like a car driving in the upper and lower passages of an overpass at the same time.

The concept of parallel universes was not proposed because of the paradox of time travel, it came from quantum mechanics, because quantum mechanics has an uncertainty, that is, quantum uncertainty. The concept of parallel universes was proposed thanks to the scientific discoveries of modern quantum mechanics.

In the 50s of the 20th century, when some physicists observed quanta, they found that the quantum state was different each time they observed.

And since all matter in the universe is made up of quanta, these scientists speculate that since each quantum has a different state, it is possible that the universe is not just one, but multiple similar universes.

On October 31, 2014, physicists said that "parallel universes" do exist, providing living space for different versions of "us". Not only that, but parallel universes will also affect each other, which is why there are all kinds of strange physical phenomena at the microscopic level.

Scholars from Griffith University in Australia and the University of California in the United States jointly proposed the above theory. They believe that parallel universes not only exist, but also influence each other, and do not develop and change independently of each other; And the interaction happens to be able to explain the strange reactions of particles found in microphysics research.

Howard Wiesman, a professor of physics at Griffith University, said: "Around 1957, the idea of parallel universes emerged in the quantum physics community. By this reasoning, every time a quantum measurement is made, a universe will give rise to a new branch universe. So there are countless possibilities - in some universes, meteorites did not hit the earth, and the dinosaurs survived. Grave

In another universe, Australia became a Portuguese colony.

According to Weisman and his colleagues, the universe in which people live is just a drop in the ocean of many universes. These universes exist at the same time, some similar to the ones people live in, and some are very different. Weisman also said that universes that are "closer" to each other will repel each other, increasing their differences from each other.

In 2015, the January issue of the Spanish monthly magazine "Fun" reported that two of the most authoritative experts in the field, physicists Andre Lind and Arangus, believed that even if there were other universes, they were in space very far away from us, and we would never come into contact with them.

Their counterparts, Paul Steinhardt and Neil Turokze, insist that parallel universes exist at different points in time.

On the other hand, Max Steg Mark and the late scientist Dennis Schalmer believed that the rest of the universe was completely far away from our space-time.

Just as Gao Guofeng and I were checking the information, a strange incident happened in the school, which can be described as creepy to those of us who went to the abandoned building that night to play the game of Disc Fairy.

Li Yanjun died, also jumping to his death from the fifth floor of the abandoned building.

The police station finally concluded: suicide.

Li Yanjun is from the Department of Physical Education, one level higher than us.

After his accident, we played the dish fairy this thing was publicized, and later I heard that before he committed suicide, people had become crazy, a little nervous, often in the middle of the night in a corner of the dormitory, either crying or laughing, from time to time scratching his head, like a woman.

"Everyone think about it, is there any way to capture this thousand-year-old soul?"

The old glasses smiled: "If he really belongs to the different dimension, this matter will be troublesome!" ”

"Oh? What do you mean by that? Director Luo asked rhetorically.

"It's easy! The space he belongs to should be above the three-dimensional space, simply put, they can see us, but we can't see them, so theoretically we can't catch him, unless ......"

"Unless what?"

"Unless you enter their space—but theoretically, that won't work, because our space exists as a physical one."

Lao Han, who never said a word on the side, stood up: "Several, let me interject a word, I have a way, but I don't know if it will work!" ”

The old glasses shook his head: "It's time for this, if you have any way, say it!" Okay, don't say that! ”

Lao Han nodded: "If everything is really the same as what Brother Xiao Liu said, this is the soul of the Chiyou twin brothers, then theoretically, if you go back to the era in which he lived, can you change all this?" ”

With that, the whole room fell silent.
