According to Einstein's famous mass-energy relationship E = mc2, it is completely possible to cross the time tunnel from now to the past. 1905, Einstein explained a "strange" world in his Special Theory of Relativity: the universe we live in can be regarded as a four-dimensional space-time. As the object moves faster, the time flow will slow down and the spatial scale will be shortened. 19 15 years, Einstein further put forward his theory of gravity, which is called "general relativity". Similarly, in this "strange" world, under the action of massive objects (that is, powerful gravitational fields), the space-time structure will bend and the time flow will slow down. One-dimensional time can be curved like three-dimensional space. 1974, Frank J. Tippler of tulane university, USA made a calculation. A cylinder with great mass and infinite length can allow astronauts to visit their past if it rotates around the axis at a speed close to the speed of light. Similarly, this is dragging light around an axis to move in a closed curve. 199 1 year, Richard Gott of Princeton University predicted that cosmic strings (which cosmologists believe were formed in the early days of the Big Bang) could lead to similar results. Scientists have found that when the spacecraft passes through the gravity field, the tension of the gravity field is converted into thrust, and the spacecraft can fly at the speed of light, even faster than the speed of light. According to the unified field theory of Einstein and German physicist Heisenberg, NASA experts established the theory of space-time field vibration. Its essence is that with the help of the elasticity of the simultaneous evolution of electromagnetism, gravity, light speed and space-time, time can be crossed instantly. However, even if it can really exceed the speed of light, the special theory of relativity also mentions that the faster an object moves, the shorter its length becomes, and the closer it is to the speed of light, the more significant it becomes. This is the so-called "Lorentz contraction"; The "general relativity" also mentioned that approaching the speed of light will be affected by the strong tidal gravity field. When it reaches the speed of light, if it is a person, I am afraid it is not a person, let alone superluminal.
So, on the other hand, "wormhole" is more reasonable.
Shortly after the publication of the general theory of relativity, Einstein discovered a theoretical "wormhole" in 1935-that is, there is a "gap" in the space-time structure composed of two connected "black holes"-a tunnel running through time and space. In other words, as long as a stable wormhole can be created, it can cross time and space. Mathematicians call this situation "multiply connected space". But theorists have never figured out that wormholes only allow light to pass through? Or can the spacecraft cross? By 1988, Thorne and Morris of California Institute of Technology finally came to the conclusion that both ends of the wormhole can enter and exit, not a one-way passage like a black hole, but can't enter and exit; Moreover, travelers are only subjected to general tension in wormholes, unlike in black holes. Also, a jeep from Berkeley University? Professor Kip Thorne also suggested that it is not enough to find such a "wormhole", but to keep it open for a long time, so that people can have enough time to enter it. Because according to quantum theory, this wormhole will close instantly under the strong action. There is a hypothesis that the anti-matter (Otone) is injected into the wormhole by quantum means such as Casimir effect, which can prolong the opening time of the wormhole. Moreover, antimatter is also used to "pull up" and drill a "time tunnel" about a light year long. Such a "time tunnel" is a "shortcut" from now to the past. This requires the integration of Einstein's "general relativity" and quantum mechanics theory to create a brand-new theory of quantum gravity. Scientists at the famous Los Alamos National Laboratory have explored how to use wormholes. They made a deeper study of antimatter: this strange antimatter has always existed only in theory, and now they have successfully proved that antimatter also exists in our real world. It is concluded that the super-strong force field of wormholes can also be neutralized by antimatter. There is an interesting difference between "positive matter" and "antimatter". The former has a "positive mass" which can generate energy, while the latter has a "negative mass" which can absorb the surrounding energy. The actual construction of a wormhole is divided into three steps: the first step is to find or build a wormhole and open a tunnel to connect two different areas in space. The second step is to stabilize the wormhole. With the negative energy generated by quantum, wormholes allow signals and objects to pass safely. Negative energy will resist the wormhole becoming infinite or close to infinite density. In other words, it prevents the wormhole from becoming a black hole. The third step is to drag the wormhole. A very advanced spaceship separates the entrances of wormholes from each other. If both ports are placed in appropriate places in space, the time difference will remain unchanged. Suppose the difference is 10 year. If the astronaut crosses the wormhole from one direction, he will jump into the future in 10 years. On the contrary, if the astronaut crosses the wormhole from another direction, he will jump to the past 10 years ago. It sounds like science fiction, but it is already a real research project funded by NASA.
Even some authorities in the field of physics believe that wormholes may naturally exist in our world on the tiny scale of Planck length (about 10-33 cm). Although this is only as small as11020 of the nucleus, theoretically, such a small wormhole can be stabilized with only one energy pulse, and then it can be expanded to a usable size. Therefore, if there is already a super civilization that can be controlled, it can even be built in a specific area of the earth's surface. 1979, American and French scientists used instruments to discover the pyramids on the seabed near Bermuda's Devil's Triangle. It is made of special materials. The tower bottom is about 300 meters long and 200 meters high. The spire is only 100 meters from the sea, which is much larger than the Egyptian pyramids. There are two huge caves at the bottom of the tower, and the sea water flows through them at an amazing speed. That is to say, the largest pyramid discovered by human beings on the earth so far is located in the Bermuda Triangle, which is located at 30 degrees north latitude, which is enough to prove that there is an unexpected close relationship between the Bermuda Devil Triangle and the Egyptian Pyramid. On the other hand, if there is an artificially created time tunnel in the future civilization, then there must be an entrance to the time tunnel from ancient times to the future, in outer space and even in a specific area on the earth's surface. There are a large number of planes and ships mysteriously missing in the Bermuda Triangle, and UFOs and USOs happen to appear frequently, so it is completely reasonable to take this as the biggest suspect (at the entrance of the time channel).
(In fact, there have been many distortions of time and space here: 196610.6 The sloop Ulysses, which set off from Aruba Island, mysteriously disappeared in the Bermuda Triangle, but suddenly appeared on the beach outside Caracas, Venezuela in 1990, and the age and physiological conditions of the three sailors on board were the same as 24 years ago; 1955 a plane that disappeared while flying over the Bermuda triangle flew back to its original destination airport intact on 1990. The birth certificate of one of the pilots shows that he is now 77 years old, but he looks only in his early 40 s. 1954 Logan and Norton's hot air balloon mysteriously disappeared in the Devil's Triangle. After many searches, there is still no whereabouts. 1990 In the Cuban spring hot air balloon competition, the hot air balloon that disappeared for 36 years suddenly appeared where it disappeared ...)
If many technical problems are overcome, the production of time machine will open Pandora's box full of paradoxes. There is one last paradox about cross-time travel, which no one can solve so far. For example, if a person really "goes back to the past" and kills his grandmother before his mother is pregnant with him, will the time traveler himself still exist? The most popular solution to the "grandma fallacy" in physics today is the "multiverse" theory-there is not only one world, but also many parallel worlds. 1957, the physicist Hugh Everett put forward the "multi-world theory" based on quantum mechanics, arguing that the universe was constantly split into two in the evolution process from the Big Bang, and the difference was the quantum transfer caused by a key event. The separated worlds were different and became multiple "parallel worlds" or "equal-dimensional universes". So far, it can be divided into three categories in theory: quantum mechanics multiverse system, general relativity multiverse system and vortex supercharged multiverse system. Moreover, in recent years, physicist Stephen Hawking pointed out that countless universes are interconnected through "wormholes". You go back to the past, but it is not your own world, but an equal-dimensional universe similar to your history. In this way, even if you kill your grandmother, she did die in that world, but when you return to the future, she is still alive and well. However, if this is the case, then a lot of factual evidence about time to go back cannot be explained. To solve this contradiction, we need to create a new hypothesis-"the principle of looking in the mirror". For example, we can see most of our body surface directly with the naked eye, but we can never see our head as the material basis for our vision without looking through the mirror. The reason why we can't see our heads is because our sight is limited in space. Similarly, the so-called "mirror" represents an "equal-dimensional space" similar to history; The "head" represents his ancestors in history and his past self (as the material basis for constructing the existing factors of "present self"). That is to say, through "going back in time", time travelers can indeed return to the real history, but due to the limitation of time and space, time travelers can never have direct contact and contact with their ancestors in history and their past selves. Murdering one's grandmother can only exist in "equal dimension". Therefore, due to past materials, present materials and future materials, some characters are different in nature. Once a time traveler is about to come into contact with his ancestors in history and his past self, the factors that exist as time travelers in the history of our world will disappear, just like the ships and planes that suddenly and mysteriously disappear in Bermuda's Devil's Triangle, and can only exist in the "parallel universe".
This not only solved the "grandmother fallacy", but also provided a theoretical basis for the fact that the ancient earth was indeed influenced by future civilization.
