According to the theory of relativity, the speed of an object can only reach 99.9% at most when it approaches the speed of light, because 99.9% of the speed of light means that the mass of the object will become 7 1 times of the original. According to the law of conservation of energy, to reach the speed of light, infinite matter must be converted into energy, and time travel only exists in theory, which is impossible in the real world.
I believe many people will always think that this is an artist's fiction when they appreciate the American film Back to 1872 and applaud the hero's righteous act of going back to the past to save Chicago citizens at the cost of his life. Because Confucius, an ancient philosopher in China, famously said that "the deceased is like a husband". How can time rush back?
However, the miracle created by the world clearly tells us that in the 20 th century, when we are about to pass, the clock has unexpectedly turned back. ?
Air adventure of Italian airliner: 1994, an Italian airliner flew over the coast of Africa. Suddenly, the passenger plane disappeared from the radar screen in the control room. Just as the airport staff on the ground were anxious, the passenger plane reappeared in the original airspace and the radar tracked the signal of the passenger plane. ?
Finally, the passenger plane landed safely at the Italian airport. However, the crew and 3 15 passengers on the passenger plane did not know that they were "missing". ?
Captain Baddary said inexplicably, "Our flight has been going smoothly since taking off from Manila without any accident, but the control room said that the flight has been lost, which is a bit unusual." ?
However, the fact is indisputable: when we arrived at the airport, each passenger's watch was 20 minutes slow. Coincidentally. According to records, a similar anecdote happened in 1970. At that time, a 727 jet was "missing" for 65,438+00 minutes on the way to Miami International Airport. 10 minutes later, the passenger plane also appeared in the same place; Then, fly safely to the destination. All the people on the plane didn't know what happened, and the reason that finally convinced them was that all the watches were slow 10 minutes. Experts believe that the only explanation for this phenomenon is that at the moment of "disappearance", time "stands still" or returns to the past.
Modern silver coins enter ancient temples: In the same year of Italian air adventure, the media revealed the miracle news that happened in Egypt 4000 years ago: an unreleased modern silver coin was buried deep underground in a temple of the sun. ?
At that time, an archaeological team composed of French archaeologists went to the area where human activities first appeared along the Nile for scientific investigation. They found a 4000-year-old temple of the sun. ?
Because of the remoteness of people, the temple has already collapsed, just in ruins, so it looks very desolate and dilapidated. When archaeologists dug up the ruins, they found a silver coin buried deep under an ancient stone tablet. Strangely, this is not an ancient Egyptian silver coin, but an American silver coin; What is more strange is that this is not an ancient American silver coin, but a modern silver coin. The most incredible thing is that this is an uncirculated silver coin with a face value of 25 cents. It has been minted and ready to enter the market on 1997, and it is still "left" in the US Treasury. Why did modern American silver coins "run" to the ancient Egyptian temple 4000 years ago? Scientists are confused.
"Witness" the construction of the pyramid: With the disintegration of the former Soviet Union, some confidential documents have been continuously made public, and scientists' access to them has also gone back in time. It was a day in August of 197 1 year. Alexander Snoff, a former Soviet pilot, accidentally "broke into" ancient Egypt while flying a conventional MIG -2 1. So, he saw the scene of pyramid construction: in the endless desert, one pyramid stands tall and the other pyramid has just laid the foundation ...?
American pilots entered the Middle Ages: 1986, an American pilot flew an SR7 1 high-altitude reconnaissance plane over the central American city of Florida, breaking through the "time-space barrier" and coming to medieval Europe. In his report to the relevant military departments, he said that when the plane flew over the treetops, you could feel the heat wave from the huge bonfire, and the piles of bodies were shocking. After investigation by experts, it was pointed out that air force pilots saw the famous "Black Death" in European history. The plague caused by the plague spread to the whole European continent, and thousands of people fell dead in the streets. This is a veritable disaster. ?
Can time go back? Although it is possible in theory, it is possible to travel through time and space when space is no longer uniform and distorted. And through the wormhole. But there is little hope in reality, and enough energy has not been found to artificially distort time and space. The distortion of time and space in the natural state is also extremely unstable. So time travel is basically a fantasy.
Extended data:
Traveling through time and space refers to moving from one space to another at different time periods (that is, switching the timeline). Time travel is feasible in theory, and human beings can open the door of the past and the shortcut of the future.
In order to realize time travel, Hawking first suggested that people accept that time is the fourth dimension. He gave a very simple example: when driving, going straight and reversing is the first dimension, turning left or right is the second dimension, climbing uphill and downhill on a mountain road is the third dimension, and then time is the fourth dimension. For physicists, just visiting may be a wormhole. Hawking said that the wormhole is around us, but it is too small to be seen by the naked eye. Everything in the universe has holes or cracks, and this basic law also applies to time. Time also has tiny cracks and gaps. The gap smaller than that between molecules and atoms is called "quantum bubble", and wormholes exist in "quantum bubble".
