Li Erdan, who has already entered the "state", heard Professor Wang Zhi say this, and he couldn't help but feel dejected, and said: "Research, research, it's all useless things. Time and space travel can't be realized at all!"

"Why, do you still want to try it?" The little old man Wang Lin said sarcastically.

"Time travel is such a fun thing, if it can be realized, who wouldn't want to try it." Dudan.

Professor Wang Zhi then asked: "If time travel is really possible, where would you like to go?"

"Uh..." Erdan was stunned for a moment, and then said: "I want to visit the Sirius galaxy. People say that there are people in the Sirius galaxy, and I want to make friends with them." After finishing speaking, this guy still laughed, It looks like the real thing.

"Hahaha, Mr. Li, you don't know something, the Sirius galaxy is finished, you go and see a hammer!" Professor Wang Zhi laughed.

Why doesn't Erdan know that the Sirius galaxy is over, the ultimate doomsday destruction, and the cycle of reincarnation is far away. The reason why he wants to go to the Sirius galaxy is definitely not out of the desire to make friends with the Sirius, but to realize Alice's "go home and see to see" wishes.

When Alice was "born" in the wandering spaceship, the Sirius galaxy had been finished for n years.Her knowledge and understanding of Sirius is all at the level of knowledge, and she has never witnessed it with her own eyes.She told Er Dan that "in her lifetime", she hopes to take a walk in the Sirius galaxy and take a look at the Sirius planet that once gave birth to the Sirius civilization.

Alice's wish is natural and easy to understand.However, it is a little difficult to realize this wish. After all, the Sirius galaxy is eight to nine light-years away from the solar system. Even if it travels at the speed of light, it will take eight to nine years. Year.And Li Erdan now has a lot of girlfriends, and no matter what, he can't spare 20 years of time to accompany Alice to "go home and see".If time and space travel can be realized, it will be different, the distance of nine light years can be reached in one duang, and the same can be returned in one duang.

Whether Alice's wish can be realized depends on whether time travel can become a reality in Li Erdan's lifetime.

After a chat, Professor Wang Zhi returned to his question, the matter of wormholes.

As mentioned earlier, wormholes exist, naturally, and there are many more, but it is very difficult to realize wormhole travel.Then, it is difficult to travel in time and space through naturally existing wormholes, can artificially create a wormhole?Or, humans modify the natural wormhole to make it bigger, gentler, and easier for humans to achieve time travel?

This problem is one of the topics that Professor Wang Zhi has studied. Similarly, many scientists in the world are also engaged in research in this area.So far, the research results are not satisfactory, or in other words, there is no progress at all, there is a lot of chicken feathers, I am confused and have no clue.This is also impossible. After all, wormholes are not ordinary things, they exist far beyond the level of human understanding.

In the past, if someone asked Professor Wang Zhi, can humans create a "wormhole digging machine" to open wormholes?Can wormholes be modified?He will uphold serious scientific thinking and say, I don't know.

Don't know, don't know, don't know, there's nothing to be ashamed of.A rigorous scientist must have the courage to say "I don't know".

But now, if someone asks Professor Wang Zhi similar questions, he will say that it is very possible, even certain.If you ask him the reason again, he will give you a living "example".

Wang Lin once entered the bottomless abyss with big ears and eyes in Lop Nur, where the machine facing the "Double Fish Gate" looked like a wormhole excavator to Professor Wang Zhi at the moment, and the Double Fish Gate was the entrance of a wormhole.

As for whether this is true, Professor Wang Zhi will try his best to confirm it with his own eyes, and in a few hours, Li Erdan and Wang Lin will also accompany him.

If there is really a wormhole under the bottomless abyss with big ears and eyes in Lop Nur, if there is really a wormhole excavator, I am afraid of the end of the world in China, because when the end comes, our 14 billion people can go to another place through the wormhole a world.Of course, there are still many question marks in all of this for the time being.

Erdan said just now that if time travel can be realized, he would like to visit the Sirius galaxy, which is eight to nine light-years away from the solar system, and "make friends" with the Sirius who no longer exists.Now Professor Wang Zhi is "taking advantage of the topic" to continue talking about his understanding of traveling through wormholes, and whether Comrade Li Erdan can reach the Sirius galaxy through wormholes.

Human beings have always thought about traveling through wormholes, so where will people go after traveling through wormholes?Can you go wherever you want?Can thinking of a certain point in time lead to a certain point in time?

Professor Wang Zhi said right now that this is by no means the case.He believes there are several possible modes for wormhole travel.

The first wormhole travel mode, that is, the pure "time" travel mode.After people pass through the wormhole, they will arrive at the past or future where they are at the moment.For example, the three of them are now on the plane, directly below is a provincial capital city full of high-rise buildings in the middle of the country.At this time, suddenly an open wormhole appeared in front of it, and the plane could not brake in time to pass through it.After a trance, the plane came out of the wormhole again, and then continued to fly, the location was still the same, the same longitude and latitude of the earth, but the time changed.If the time is tens of millions of years earlier than now, looking down from the plane, you will see a primitive jungle with various dinosaurs in it, instead of the original provincial capital.If you travel to the future, what you see is likely to be a city full of holes like the doomsday.

The second wormhole travel mode is a simple "space" travel mode.Still at this moment, the plane passes through the wormhole, and after it comes out, it is no longer above the provincial capital. Anywhere on the earth is possible, even on alien planets.

The third wormhole travel mode, time travel mode.In this mode, after traveling through the wormhole, human beings will reach a place in the past or future that is different from the present.

There are also some overlaps between the above three wormhole traversal modes. For example, the third traversal mode includes the first and second modes to some extent, but it is generally correct to subdivide them in this way.In addition, the above three time-travel modes all have a common premise that there is only one universe. in a universe.
