Science and technology, like a magic key, completely reshaped the face of human life and continued to shape its destiny。

Driven by the power of technology, human dreams continue to renew over time. In the distant ancient times, every inch of the earth's land is a distant luxury. However, with advances in science and technology, these dreams have long gone into reality。
Today, human beings are not only able to travel across the globe, but also to the vast universe, opening a new era of space exploration。
The vision of the modern man is no longer confined to the blue planet of the earth. Exploring every corner of the universe has become a new quest. What is more, there is a desire for one day to travel through time and space and to travel freely between the past and the future。
Since einstein's great relativity, the topic of space and time travel has skyrocketed and attracted countless attention. It is also a source of inspiration for many writers to create a great number of time and space travel novels。
So, is time travel an illusion or a possibility of a scientificly based reality
The theory of relativity gives positive answers at the theoretical level, and time travel is theoretically feasible, especially through to the future, where it is highly likely to be achieved. Scientists have come up with four promising approaches。
First, we can use speed to travel to the future。
Einstein's relativism shows that the speed of the object is closely related to the speed of the passage of time, the faster it is, the slower it is。

It needs to be noted, however, that the speed of a mass object can only be infinitely closer to the speed of light but cannot be reached or exceeded. As a result, the speed of light is as high as an inescapable mountain, and at present our ship can only approach the speed of light indefinitely. Even so, such a flight near the speed of light can help us realize our dream of crossing the future。
Perhaps one would ask whether it would be possible to travel in a normal ship at a faster pace, so as to travel to the future
The answer is no。
While relativism reveals the mystery that time can be distorted, the impact of speed on time is not simple. In the case of traveller 1, the speed of flight is as high as tens of kilometres per second, which appears to be extremely rapid. However, even at such speed, even for a light year, when we return to earth, the passage of time on earth is not obvious and it is difficult to achieve a true journey through the future。
For a significant future to cross, the speed of the ship must be unlimitedly close to the speed of light。
Under the narrow relativist bell slow effect, when the ship returns to earth at 99. 9999999985 per cent light speed, 500 years of time have passed; if the ship's speed rises to 99. 999999999252 per cent, the earth's time will pass 10,000 years。
So it turns out that only if the ship's speed reaches 99% and above can it really travel to the future。

Moreover, the closer the speed to light, the greater the time span. With the rapid development of human technology, achieving sub-light speed is not an impossible dream. Of course, it will take a long time and tireless effort to reach 99% of the speed of light。
Einstein's relativism also states that objects of immense mass can distort the surrounding space and time. In our eyes, the seemingly calm universe, if it is amplified countless times, will find the entire space full of distortions and quails. These are radon generated by space-time distortions, and outward radiation forms gravitational waves. The gravitational wave was initially einstein's theory of relativity, and it was not until 2016 that scientists successfully detected the gravitational wave in the universe for the first time, making it a reality。
Second, the use of gravitational waves to complete time and space travel。
Gravity waves have the magical power to change time and space, and theoretically we can use them to achieve time and space travel. In many science fictions, spacecraft often use gravitational waves to break space constraints and jump into space, thereby rapidly reaching distant galaxies. Theoretically, such hyper-light-speed space leaps are equally capable of altering the time processes of time and space and thus achieving future travel。
Third, wormholes cross。
The space of the universe is vast and humans are currently observing 93 billion light-years of hubble, but this may be just the tip of the iceberg of the universe. Scientists speculated that the entire universe could reach hundreds of millions of light years and was still expanding at an alarming rate。

In such a vast universe, exploration based solely on sub-light speeds is undoubtedly the price of water。
In order to address this challenge, the einstein theory of relativity is based on a wormhole。
The wormhole is like a mysterious passageway connecting time and space. We can understand the principles of wormholes by using a piece of paper: imagine space as a white paper, two remote points on which are not normally within reach. But when we fold the paper, the two points are infinity. At this point, the two dots are crossed with a chopstick, which is like a wormhole that connects two dots, and through a wormhole, the distance is shortened instantaneously, achieving immediate arrival。
Wormholes are passageways formed in extreme space distortion, and due to extreme time and space distortion, theoretically wormholes can slow the clock indefinitely, thus allowing us to cross the long river of time to reach the future。
Fourth, refrigeration technology。
The first three ways through the future are based on theoretical conjectures of relativity. Even if time and space travel were to exist within the framework of relativity, it would not be a one-off event, and it could take thousands, if not tens of thousands, of years of long exploration。
Unlike the first three methods, human refrigeration is a technology that has already been applied initially。

We all know that some animals go to hibernation in winter, and during hibernation the metabolic rate in animals is significantly reduced, thus saving energy consumption. Inspired by this, scientists have begun to study refrigeration techniques in an attempt to bring all cells in the body to hibernation by physically cooling the body and significantly reduce its energy consumption。
Ideally, advanced refrigeration technologies could even bring the energy consumption of humans closer to a halt。
When human cell activity is significantly slowed down or even stopped, time becomes meaningless for the frozen. After thousands of years and tens of thousands of years, if the thaw is successfully unfrozen, the man will be able to recover and begin a new life. As a result, human refrigeration technology is an extremely promising way to travel through the future and the most likely route to be achieved in the foreseeable future。
Time travel is theoretically feasible and attracts the attention of numerous scientists, including prominent physicist hawking. Hawking has a lifetime of intense interest in time travel and, after extensive research and exploration, has provided his own unique insights. On 28 june 2009, hawking hosted a famous “future dinner”, an act that fully demonstrated his firm belief in the realizability of time travel。
However, hawking has also warned that if humans travel successfully in the future and travel through the future, it may not be a serious problem, but if they travel back into the past, there is a great risk of changing the course of history, triggering a severe butterfly effect, with unpredictable and terrible consequences for real time and space。
