If the spaceship flies at the speed of light 1000 light years, what will happen to the people in the spaceship?

Scientists have been studying the breakthrough of speed, hoping to develop the technology of light speed and superlight speed. If human beings can develop the technology of the speed of light, we can easily get out of the solar system, and we can also explore some star systems near the solar system, look for terrestrial planets and carry out real interstellar migration. It can be said that the speed of light flight is of great significance to human beings, and it is the key to determine whether human beings can enter the galaxy civilization.

Someone once asked a question: If the spaceship flies at the speed of light 1000 light years, what will happen to the people in the spaceship? You know, it takes 1000 years to fly to a planet 1000 light years away at the speed of light, but the life span of human beings is only about a hundred years. When we reached the target planet, did everyone on the spaceship die?

That was not the case. According to the time expansion effect mentioned in Einstein's theory of relativity, a moving object moves slower than a stationary object, and the faster the speed, the slower the time passes. When the speed of an object reaches the speed of light, time and space are meaningless, that is, the time when an object flies at the speed of light is static.

The spaceship flew 65,438+0,000 light years at the speed of light. To the outside world, it is indeed 1000, and people on earth will know that the spacecraft has set off 1000. But for the spacecraft itself, because it is flying at the speed of light, the time in the spacecraft will be static, and the people in the spacecraft will not feel the passage of time and the years will not stay on them.

Many people may say that it is immortal, and it is immortal in disguise. As long as the spacecraft keeps flying at the speed of light, the people inside the spacecraft will never get old. Theoretically, it is. I believe many friends have read some science fiction. The protagonist travels at the speed of light in the universe. When he returned to the earth, thousands of years had passed and the protagonist was not old.

In fact, whether the speed of light is flying or not, scientists do not have a definite answer. I'm just speculating based on Einstein's theory of relativity. What is the real situation? Only when human beings really realize the speed of light can we really detect it. Some people may say that according to Einstein's theory of relativity, the speed of an object can only be infinitely close to the speed of light, and it is illegal to fly at the speed of light.

So is this really the case? Of course not. According to Einstein's theory of relativity, the speed of an object cannot reach the speed of light, but scientists have observed objects flying at the speed of light in the universe, and even objects faster than the speed of light have been observed. Existence is scientific. With the continuous progress of human science and technology, we will also develop real light speed flight technology. To do this, it is mainly energy. As long as the energy is strong enough, it can be said that a powerful engine can be made, and flying at the speed of light is no longer a dream.

This energy includes controlled nuclear fusion, dark energy and so on. , especially dark energy. Modern scientists have discovered dark matter in the laboratory and the existence of dark matter in the universe. The energy produced by the collision between dark matter and positive matter is huge, and the dark energy is far beyond the existence of nuclear fusion energy. If human energy really grasps the use of dark energy, let alone flying at the speed of light, it is possible to fly at faster than light.
