You know, this old-fashioned "member card" is unique to the Soviet Union. When the young man Shi Shiran took out such a thing, the policeman who questioned him immediately felt insulted. They think this young man who plays "cosplay" needs to go to the police station to calm down. After all, according to the age on the certificate, he is 74 years old.
After careful consideration, the police sent Sergei to the hospital first.
In the face of the doctor's inquiry, Sergei claimed that he was from 1958. At that time, he was just taking pictures with his camera. Suddenly, he found a strange thing in the sky. Took a photo, everything around him changed dramatically, and then he went to the place where he appeared.
At that time, few people believed Sergei's words. Everyone thought he was a man with a brain problem and locked him in the ward. However, one day later, Sergei once again let people fall below the glasses, and he once again "disappeared out of thin air"! No one knows where he went. The only thing left is his camera.
It has been confirmed that this camera is indeed a product of the 1950s and 1960s. People also developed two photos from the film in his camera, one of which was a photo of him and a lady, and the other did see a black shadow in the sky. The woman in the photo has also been confirmed by People. She is indeed an old woman in her seventies. As for Sergei, she claimed to know him, but she disappeared in 1958.
The above is the detailed process of "Sergei crossing event". At that time, after the news broke out, many people speculated that Sergei really traveled through time and space. Or someone's prank?
"Grandfather Paradox" For this confusing event, quite a few people are willing to believe it is true. They firmly believe that Sergei is a time traveler, and time travelers may exist around us.
There are also many people who disagree that this is just a prank. There are deliberate marks in many places. The most obvious one is that there is no camera that came back with Sergei. Opponents also believe that there can be no time travelers in the world, and "time travel" itself is a paradox. For this view, their main theoretical basis is "grandfather paradox".
What is "grandfather paradox"?
"Grandfather Paradox", also known as "Grandmother Paradox" or "Grandfather Paradox", was not put forward by any scientist, but by a science fiction writer. In his works, he once mentioned such a paradox: if a person can travel back to the past, go back to the time before his mother was born and kill his young grandparents, then his mother will not be born, so there will be no crossing.
In this famous paradox, there are many contradictions about crossing, just like butterfly effect. Even if you go back and make a slight change, it may have a far-reaching impact on the crossing itself. This kind of interaction, many phenomena can not be explained, the scene can not be imagined.
Accordingly, people who believe in the "grandfather paradox" insist that there will be no walkers in this world and there can be no walkers.
Is the "grandfather paradox" really unsolvable? Not exactly. In the process of solving "grandfather paradox", people thought of the term "parallel universe".
In the "parallel universe theory", people think that our world is not single, but diverges in many directions. Generally speaking, there are many parallel development worlds, and their starting point is the different choices we make every time. Everyone's timeline has spawned countless parallel development worlds.
It is much simpler to explain the "grandfather paradox" with "parallel universe".
If a person travels back in time and kills his grandparents before his mother is born, at that moment, the original universe has already become another parallel world. The traveler will not disappear, because his grandparents still exist in the original time and space, and he will not appear again in this time and space where he has just "transformed".
Conclusion: The view of "parallel universe" opens people's minds. Many unexplained things can be explained by "parallel universes", but in any case, "crossing time and space" or "parallel universes" are just people's guesses. Humans can't even break through the speed of light now, and the road ahead is still very long.
As for whether there are time travelers, no one can give an accurate answer yet. Maybe one day in the future, human beings can solve this problem.
Do you believe in time travelers?
Time travel has been a fascinating and mysterious proposition since ancient times, and countless sci-fi works and movies have revolved around it. It contains the fantasies and longings of countless people.
Whether it's The Avengers or Back to the Future, these movies all involve time travel. People yearn for it infinitely. When it comes to time travel, we have to mention the "grandfather paradox".
Grandfather Paradox is also called Grandmother Paradox. To put it simply, suppose a person goes back to the past and kills his grandfather or grandmother who is still young and has no children. Then there will be a grandfather paradox. Suppose my grandfather was killed, then this person's mother would not be born, and neither would she. Then the question is, if you were not born, who killed my grandfather?
At this time, the grandpa/grandma paradox came into being.
There are several views on this paradox. One is that time is irreversible and there is no time travel at all.
But for many science fiction lovers, this statement is obviously unacceptable.
So there are two other versions.
One is that time travel exists, but there is a rule to forcibly correct what has happened, which means that even if you realize time travel, you can't change anything that has happened. Once forced to change, there are rules that will be corrected. What you have done is useless.
There is also a setting, like Zhao Gao and Yi Xiaochuan in the myth. When you participate in history, you become a part of it. No matter what you do, it just happens to be history and cannot be changed.
And there is a kind of setting is parallel universe, the first two years of "The Avengers" is to follow this setting.
When you travel through time and space and change history, just like killing your grandfather in the grandfather paradox, a new timeline will be created. That is, parallel worlds. In the old world, this man still exists.
In the new timeline, my grandfather died when he was young. No children, and no one killed my grandfather. In the original timeline, nothing has changed. This is just a new timeline.
In a word, this is a very mysterious and desirable thing.
As for whether there is a passer-by, it can only be said that so far, no one can be sure that it is a passer-by. There are many people who are suspected of crossing through the ages.
For example, Wang Mang, who was very popular on the Internet before, and Wulitou tablet. There are also super-ancient shoe print fossils found abroad.
But after all, it's just an inference. Some people on the internet call themselves travelers, but it's a pity that it's basically just a farce.
