Can time really be distorted? The scientists finally found the answer through experiments

This paper takes part in the series essay competition of “great science” of Recordunkown.

13.8 billion years ago, a mysterious singularity exploded. After the big bang, the universe was born. At the moment of the birth of the universe, two things were born, namely time and space. Time and space, which we often combine now, are called spacetime.

Since human beings entered the era of science and technology, they began to study and explore time and space. The complexity and mystery of time and space are also very different. Relatively speaking, space is easier for us to understand and explore, because the world we live in, the universe is a vast space, and we can really see and feel the love of space Some phenomena and mysteries.

In the research and exploration of space, scientists found that space can be distorted, and the most obvious one is the rapid expansion of the universe, which is far faster than the speed of light. We should know that the birth time of the universe is only 13.8 billion years, and the observable cosmic range of human beings has reached 93 billion light years, and this range is just the tip of the iceberg of the universe. This shows how fast the universe is expanding. It is faster than the speed of light.

The expansion and redshift of the universe are telling us that the universe is not a plane, not a stable existence, but a complex mystery that can be distorted. Since space can be distorted, can time, which appears simultaneously with space, also be distorted?

For the exploration and research of time, the progress of scientists is very slow, which can be far less profound than the understanding of space. The reason is very simple, space is a real existence, which can be observed and studied by us, but time is more like an illusory existence, we can’t see what the real time is like? I don’t know what the essence of time is? Some people even think that time may not exist, it’s just our imagination.

Some people may say that we are dealing with time every day, 365 days a year, 24 hours a day. Isn’t that time? Why do people think time doesn’t exist? In fact, the time we know now is only defined by human beings, such as 60 minutes an hour, 60 seconds a minute, etc., which are all defined by ourselves.

If there are alien civilizations in the universe, the definition of time may be very different for different alien civilizations. 100 civilizations may have 100 definitions of time, so which one is right? It is possible that none of them is the real essence of cosmic time. Since we don’t know what time is, can we explore whether time can be distorted?

In the scientific world, exploring many unknown things need to be proved by various experiments. Although we don’t know the essence of many things, we can get the results through some experiments. For example, we don’t know the essence of many strange phenomena in quantum mechanics, but we can get the results through experiments. After proving the results, we can deduce the process slowly.

Newton studied the formula of universal gravitation in those years. He got the result through an apple experiment, then studied it slowly, and finally got the formula of gravitation. The same is true for the exploration and study of time. We still can’t understand what the essence of time is? But we can prove some results through experiments.

For a long time, people have always thought that time is invariable in the passage of time, time is average speed, there is no fast or slow. We experience the same amount of time every day, neither fast nor slow. But this kind of cognition of time was later broken by Einstein. After Einstein put forward the theory of relativity, he had more cognition of space and knew that space can be distorted.

So Einstein thought of a question: since space can be distorted, what about time? So Einstein put forward the theory of time distortion, that time and space can be distorted. After the theory was put forward at that time, many people questioned it. They thought that time is going through every day and we didn’t find that time is getting faster and slower. How can it be distorted?

But as time goes on, people gradually find that Einstein’s theory is correct and time can be distorted. The reason for this conclusion is that scientists have carried out several related experiments. I believe many people know that “time slow scale contraction”, also known as “clock slow scale contraction”, comes from Einstein’s special theory of relativity. It describes the relationship between movement and time. In short, the faster the speed, the slower the time.

In 1971, physicist Joe huffler( Joe.Hafele )With Richard Keating( Richard.Keating )A flying atomic clock experiment was designed. They placed a high-precision atomic clock on the plane and flew around the earth. Then they compared the time readings of the atomic clock on the plane with those on the ground. The experimental results confirmed the authenticity of the “time slow scale” for the first time.

In 1996 and 2010, the National Physics Laboratory (NPL) carried out two similar experiments using a higher precision atomic clock, and the experimental results are basically consistent with the formula of “time slow scale”. These experiments have confirmed that with the increasing of the object’s speed, the time it takes is shorter.

I believe many people know the theory of light speed limit put forward by Einstein’s theory of relativity, that is, the speed limit of an object is the speed of light. When the speed of an object is infinitely close to the speed of light, its time is infinitely close to static.

In addition to the “clock slow scale” effect, Einstein also proposed the “gravitational time expansion” effect. This theory tells us that in a gravitational field, the greater the mass of the gravitational source, the shorter the time that the object in the gravitational field experiences, and the farther the object is from the gravitational source, the longer the time it experiences.

And the theory of “gravitational time expansion” has also been confirmed, and it is also widely used in modern communication technology. For example, the core theory of our current GPS system is the “gravitational time expansion” effect. The GPS system is strictly adjusted according to Einstein’s relevant formula, otherwise we can’t carry out accurate positioning at all.

Through the experiment of the above theory, we come to the conclusion that time can also be distorted. Although the phenomenon of “time warp” has been confirmed by scientists, due to the limitations of human science and technology, we can not really apply time warp to achieve higher research and exploration. The reason for this is that our spacecraft’s power technology is still very backward, and we can’t make the speed of the spacecraft close to or even exceed the speed of light.

And we still can’t get the spacecraft close to the massive objects in the universe, such as neutron stars and black holes. Some scientists speculate that the region, time and space inside the event horizon of the black hole may have been seriously distorted, where time may be very slow, or even at a stop. If we can drive the spacecraft into the black hole, it is possible to realize the passage of time and space,

If time and space can be distorted, then is the legendary time-space crossing and time crossing real? Theoretically speaking, since time can be distorted, space-time travel should exist, but we can’t prove such a thing now. If time machine really exists, why don’t future human beings come to modern times by time machine? There may be more mysteries.

Of course, the fact that time warping has been confirmed by scientists only lets us know that time really exists, how the process of time warping occurs, and what’s the mystery? We still know nothing about this huge mystery, we can only wait for scientists to explore and study. Time and space are the most mysterious things in the universe, and may also be the ultimate mysteries of the universe. If we really understand time and space, we may be able to cross the universe, cross the river of time, and truly become the overlord of the universe.
