The universe is vast and there are countless mysteries waiting for human beings to uncover. The distance in the universe is calculated in light years. The biggest constraint for human beings to really explore the universe is speed. Without speed, we can’t get out of the solar system or the Milky way. At our present speed, it will take tens of thousands of years to fly out of the solar system, let alone the Milky way.
If the human spaceship can reach the speed of light, will it be able to explore the universe? In fact, the speed of light is not fast in the universe. For example, scientists now think that the diameter of our solar system is 1 light year. It takes a year for a light speed spacecraft to fly out of the solar system, while the diameter of the Milky way is 100000 light years. Even if we fly at the speed of light, it takes 100000 years for a spacecraft to fly out of the Milky way.
According to Einstein’s phase theory, the speed of an object in vacuum can only be infinitely close to the speed of light. Can we never achieve the speed of light? Of course, it’s not. The speed of the object itself can’t reach the speed of light, but the speed of space can. This is what we can see in movies and science fiction. Through the compression and expansion of the space before and after the spaceship, the spaceship can fly at the speed of light or even beyond the speed of light.
So someone asked a question: if the speed of the spaceship reached the speed of light, what would the people in the spaceship feel? According to the theory of relativity, the time of a moving clock is slower than that of a relatively stationary clock, and the faster the speed is, the slower the time passes. When the speed of an object reaches the speed of light, the time stops completely. At this time, no matter how far the spaceship flies, even if it flies 1000 light years away, the time that people inside the spaceship feel is only a moment. In fact, the time outside the spaceship may have passed 1000 years.
In ancient Chinese mythology, there is a saying that one day in the sky and one year on the earth, which the ancients did not understand. However, modern science can make some guesses about it. It is possible that there was a passage similar to the time and space tunnel on the earth in ancient times. In fact, it is also a kind of space passage. Some people accidentally enter such a passage, because the speed in the passage can reach the speed of light, and it is possible for human beings to enter I feel that time is just a moment, but in fact, many years have passed in the outside world.
Many people doubt whether the speed of light is true or false, but in reality, scientists have found the phenomenon of the speed of light in the laboratory, and even superluminal phenomenon. In the universe, the phenomenon of the speed of light is not uncommon, and even superluminal phenomenon has been observed by scientists. It can be seen that the speed of light and superluminal phenomenon are absolutely not fantasy, but real existence.
Since the universe exists, and the universe is vast, if the speed is always limited to the speed of light, what is the significance of the existence of the universe? Since the universe exists, it must be possible to explore. To explore the universe, the speed of light is only the basic speed, and superluminal speed is the mainstream.
Now, the curvilinear engine that some scientists are studying is a way to realize the superluminal speed by using space. Its principle is to compress the space in front of the spaceship and expand the space behind the spaceship at the same time. In this way, the space before and after the spaceship is compressed and expanded, and the space is distorted, forming a superluminal channel. When the spaceship moves at superluminal speed, it drives the spaceship to fly at superluminal speed Like surfing on the earth, the ups and downs of the waves carry the boat fast forward, while the boat itself is motionless.
Of course, the speed of light and superluminal speed are still a little far away for us. Now it’s just a theoretical stage. It’s still a long way to go to really realize the speed of light flight of spacecraft. We can’t imagine what kind of experience the speed of light flight is, let alone superluminal speed. If the speed of light flight can make time stand still, can superluminal speed flight make time retrogress? Perhaps in the future, it is not impossible to go back to the past through time and space. There is no end to science. There is no science that can not be realized, and it can not be realized, which means that science has not developed to that extent.
