In Bai Juyi's "Long Hate Song", there is such a sentence, "I overheard that there are immortal mountains on the sea, and the mountains are in the void." According to legend, after Ma Song mutinied Yang Guifei was killed, Yang Guifei's soul neither entered the Heavenly Palace nor entered hell.
Instead, I came to an overseas fairy island, and this immortal mountain is Penglai Mountain. From Bai Juyi's poems, it can be seen that this Penglai Immortal Mountain is filled with ethereal immortal qi, which will make people lose their way.
There are strange flowers and grasses on the mountain, pavilions and pavilions, golden splendor, and many fairies with graceful postures. Before the Tang Dynasty, Penglai Mountain has always had the legend of a sacred mountain. According to legend, there are three sacred mountains in the Bohai Sea, called Penglai, Abbot and Yingzhou.
Performance of "Long Hate Song"
These three mountains are inhabited not only by immortals, but also by elixirs of immortality. Qin Shi Huang had seen these three sacred mountains with his own eyes on the seashore, so he was convinced of the existence of the sacred mountains.
He even sent the alchemist Xu Fu three times to search for Penglai Immortal Mountain in order to find the elixir of immortality. Until now, Penglai Mountain has also appeared in literary novels under the name of Xianshan Mountain.
However, with the development of science, people no longer believe in the existence of gods. Some people believe that the Penglai Mountain that Qin Shi Huang saw was just a mirage, but some people think that the Penglai Mountain that appeared on the sea is the reflection of another parallel universe.

The universe is the place where human beings live, and at the current level of science, human understanding of the universe is extremely limited. However, this does not prevent scientists from imagining and conjecturing the universe infinitely.
In 1895, the American philosopher William James proposed the multiverse theory, also known as the multiverse theory. Multiverse theory holds that there are universes besides the one we know now.
The relationship between these universes may be equal, or it may be a relationship between superior and inferior. This view is somewhat similar to the Buddhist view of the universe "Three Thousand Worlds".
Limited by current scientific means and the level of astronomical observation, the universe we now recognize is finite, and it is not the whole picture of the entire universe. The remaining space that has not yet been observed is infinitely large.
Multiverse imagination map
This is the theory of the infinite universe, also known as the open universe theory. By far the most far-reaching of the various conjectures about the universe so far is the Big Bang cosmology proposed by the American physicist Hamov in 1946.
The Big Bang cosmology explains the origin of the universe. In the beginning, the universe was just a singularity, and later this singularity continued to expand and become larger.
Finally, a rapid expansion similar to the Big Bang occurred, forming the prototype of the universe as we know it now. The expansion of the universe has not ended, and until now the universe has been expanding outward.
In addition to these conjectures about the universe, there is also the bubble universe theory, the big bounce theory, the m-theory, and the parallel universe theory. The most interesting of these theories is the theory of parallel universes.
Simulation of the cosmic explosion
In the whole large universe, there are many other universes, and the universe in which human beings live is only one of them. Part of these universes is differentiated from a primitive universe, with a mother-to-child relationship.
There is also a part of a relationship that is completely equal. There may be similar things in different universes, with similar historical processes, similar environments, of course, they are not exactly the same, just the large background is similar, but the small aspects are completely different.
For example, dinosaurs are completely extinct in the universe we live in, but according to the idea of parallel universes, dinosaurs may still exist in other universes. And these universes are not like the tangyuan in the bowl, only the boundaries can be next to each other.
Parallel universe imagination map
Some universes may overlap completely, but because they are in different spaces, they cannot find each other. That is to say, in the whole large universe, there are still many selves.
They may have the same appearance, similar life experiences, similar personality traits, but they may go to different lives. This is the view of parallel universes. Parallel universes are not only a very interesting concept in physics, but also a common element in many science fiction novels and science fiction movies.
Imaginary map of the universe overlapping
There are many elements of "parallel universes" in the high-scoring animation "Rick and Morty", and they often travel through different universes and meet themselves in other universes. Rick also said, "There are countless parallel realities that we can quietly replace our dead selves in this world."
In the American drama "Relative Universe", it is directly set in two parallel universes. The male protagonist living in our universe is an ordinary clerk, honest and honest, and conscientious in doing his job.
The male protagonist in another parallel universe is a social elite who controls the overall situation of the world. Because of an accident, the world split into two parallel universes, and there is a passage between the two universes for people to travel back and forth.
Stills from Relative Universe
There is also the topic of rebirth and crossing that is more popular now, in fact, it is also influenced by the theory of parallel universes. In the novel, the protagonist is reborn and returns to the past, perhaps not really going back in time, but he enters a parallel universe.
The time flow rate of this parallel universe is slower than the time flow rate of the original universe, so the protagonist can "go back" to his childhood, and the same is true for crossing. Since crossing and rebirth have certain theories as support, can we find a passage to other parallel universes in the real world?
Imagine a theme through time
One day in June 2015, people in Chengde City, Hebei Province, were still working, studying and living step by step. However, when some people looked up at the sky, they were suddenly shocked, because they found that an antique building had appeared in the original blue sky.
It is said that this building is located among the clouds, somewhat similar to the Chengde Mountain Resort, and also a bit like the "South Heavenly Gate" in Chinese myths and legends. As a result, witnesses speculated that this might be the "South Heavenly Gate" of the Heavenly Palace, a passage to another world, a tunnel that could be crossed into parallel universes.
According to the view of parallel universes, there may be a parallel universe similar to ours, but not exactly the same, then the "South Heavenly Gate" in Hebei does meet this condition.
The "South Heavenly Gate" that people photographed
The "South Heavenly Gate" in Hebei is similar to ancient architecture, but it is not exactly the same. However, after all, the theory of parallel universes is only a hypothesis and has not yet been scientifically verified, so whether the "South Heavenly Gate" in Hebei is a passageway for parallel universes remains to be examined.
Some people believe that Chengde City, Hebei Province, is very close to the Bohai Sea, and the local air humidity is relatively large, so the "South Tianmen" in Hebei is just a refraction phenomenon of light, and people see only a mirage.
Moreover, the probability of mirages appearing near the Bohai Sea is also very high, and Qin Shi Huang once saw the mirages of Penglai and Yingzhou on the seashore. In response to this view, some skeptics believe that the mirage reflects things that exist on the ground, but the "South Heavenly Gate" in Hebei cannot find a prototype in the world.

In addition, some people believe that hebei's "South Tianmen" is just a farce of false rumors. In 2015, mobile phones have become very common, and many people already have high-pixel mobile phones.
Just like the "South Heavenly Gate" in Hebei, which appears in the sky and appears suddenly, it can also be clearly photographed. However, searching for the keywords "Hebei 'South Tianmen' Pictures" on the Internet, the pictures that come out are different, and some can even be clearly seen to be technically processed.
In a situation where smartphones are so common, there is not a single exact picture, which is obviously very abnormal. Moreover, a search for "Hebei South Tianmen" can be found that there are three places named after the South Tianmen in Hebei Province.
They are in Shijiazhuang, Hebei, Kangbao County, Hebei Province, and Xinglong County, Hebei Province. Therefore, the "South Heavenly Gate" in Hebei may be a rumor, and it has not really appeared at all.
Reflection and refraction are both two concepts of optics in physics. Reflection means that when light travels to an object, all of this light is not absorbed by the object, and a part of the light will change the direction of propagation on the surface of the object and return the light according to the original path.
For example, sunlight is projected into the ground and re-reflected back by the ground. And when we use the mirror to point at the light, the light will also be reflected. Refraction is the shooting of light from one substance into another.
Both substances are required to be transparent, at which point the direction of light propagation will be changed and will not be returned to the original material like a reflection. A mirage is a natural phenomenon formed after light is reflected and refracted, also known as a mirage.
It is formed by the sunlight first being projected onto the ground, then reflected by the ground back into the atmosphere, and refracted in the atmosphere. The conditions for the generation of mirages are very high, and the geographical location, meteorological conditions, air humidity, temperature, etc. must be strictly required.
Deserts, Gobi, snowfields, and calm seas, lakes, and rivers are more likely to have a mirage as a natural wonder. China's record of mirages can be traced back to the Qin Dynasty.
After Qin Shi Huang sealed Mount Taishan, he once saw a mirage on the shores of the Bohai Sea. The last mirage in China was on June 28 this year, in the southern sky of the second phase of the Teachers' Apartment of Zhuhai College of Beijing Institute of Technology.
Deserts are more prone to mirages
Hebei's "South Heavenly Gate" may be the gate of parallel universes, or it may be a mirage, or more likely to be a rumor on the Internet, so it cannot be used as evidence for the existence of parallel universes. So, is there any other evidence to confirm the theory of parallel universes?
In 2013, Mandela died, but many people's memories were confused. In their memory, Mandela died in the 1980s, and his supporters held a grand memorial service for him, but none of this really happened.
This phenomenon of collective memory discrepancies from real facts is known as the "Mandela effect." Some scientists believe that the reason why these people's memories are biased is because of the existence of parallel universes.
Based on memories associated with Mandela's death, the Mandela effect was proposed
In parallel universes, Mandela did die in the 1980s. They are influenced by parallel universes, so that memory is confused, and the "Mandela effect" is also seen as evidence of the existence of parallel universes.
Another important piece of evidence for parallel universes is the "Schrödinger's Cat", which is better known to everyone. In 1935, Austrian physicists came up with the idea of "Schrödinger's cat".
Place a cat in an airtight box with a bottle of cyanide in this space. If the radium in the air decays, it triggers the mechanism, the cap is opened, and the cat is poisoned.
Schrödinger's cat simulation
If the radium in the air had not decayed and the cap could not be opened, the cat would not have died. There is a certain chance of radium decay, but no one knows whether the cat is alive or dead until the box is opened.
Scientists believe that this cat in one parallel universe is dead, and the cat in another parallel universe is still alive, so this cat is both dead and alive.
If there really were parallel universes, what would it be like to have a self in another universe? Curiosity makes many people want to explore parallel universes. Parallel universes are conjectures and assumptions made by scientists.
Whether there really is a parallel universe still needs to be scientifically verified by scientists. We must believe in the power of science, believe in scientific points of view, and don't start to speculate for no reason because there are rumors on the Internet that have no authenticity.
