The space-time jump engine, with the word jump added in the middle, shows that it has nothing to do with space-time travel. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 infoLi Yu will develop a real space-time engine someday in the future, but not now.

Although wormholes also connect different spaces to achieve ultra-long-distance space navigation, it is also flawed. The farther artificially created wormholes communicate, the more energy is required, and the wormholes generated by the universe itself may not consume much energy, because many naturally generated wormholes are annihilated after they are generated.

For the universe, the energy consumed to naturally form an ultra-long-distance wormhole is a drop in the mare of a dime, but for a spaceship, beyond a certain distance, if you want to use a wormhole to sail, you must increase the energy level.

Of course, this defect is not too big a flaw for Li Yu, it is a big deal to upgrade the energy, but if there is a better choice, then wouldn't it be stupid not to use it?

There is another disadvantage of wormhole navigation, and that is the problem of time. Wormhole travel is instantaneous to destination, however, time is not consistent in the universe, and time needs a frame of reference to make sense.

If the space-time jump engine can unify the time of different frames of reference, it can save a lot of trouble.

Due to the introduction of anti-energy, the space-time jump engine is the first choice in terms of sailing limit, surpassing the space jump engine, and the first-generation space-time jump engine researched by Li Yu in front of him has already reached a sailing limit of one million light years.

"Do you want to upgrade our ship's engines? The newly built spaceship is about to start construction, so you always feel that it is not appropriate, right? "For Sun Yixuan, the new spaceship is a new home, and it has only been a year since she moved in, and she has made major changes and started construction, which is too confusing.

"This is normal, the technology upgrade of the laboratory is very fast, it has only been a long time since the laboratory was established, and the spaceship technology has been upgraded for three generations, one engine, it's a little meaning!" Lin Wanbai comforted Sun Yixuan with a nonchalant attitude.

"That's it! Besides, Li Yu will definitely take this into account, and upgrading the engine will not make major changes to the spaceship. Fang Qianmo also comforted Sun Yixuan in her own way.

"Replacing the engine, in fact, it doesn't take much to do it, the space-time jump engine is also developed on the basis of the space jump engine, combined with space teleportation technology, and the technical system is also in the same line, so the changes to the spacecraft will not be too big."

"The biggest change is to change the engine's energy supply mode, which requires manual addition of antimatter to the engine. This change doesn't take up much space, so overall, just replace the current space jump engine, and the overall change is not much. ”

After listening to Li Yu's words, Sun Yixuan's last trace of worry disappeared, so she asked Li Yu: "We still have to stay in this star for at least a year, and there is enough time to replace the engine, or Li Yu, you should make some improvements to the engine, and then change the equipment!" ”

"Of course we won't change the engine now, the technology in our laboratory this time will definitely undergo a major upgrade, and if we want to upgrade the spaceship, we will have to wait until this technical upgrade is over, so you don't think we will only upgrade the engine, right?"

As soon as Li Yu's words fell, Sun Yixuan knew that he was thinking too simply, it seems that what Li Yu said about not making major changes is actually just the shell of the spaceship unchanged, and everything else is basically changing!

Forget it, I've heard Fang Qianmo say a long time ago, after less than a year of testing around the galaxy, the interior of the space has changed, and with a precedent, don't be surprised.

"Li Yu, the representatives of the six civilizations have sent a letter, and they have something to meet with you to discuss in detail." Yui interrupted the discussion about technology.

"What's the matter with them?" Li Yu was puzzled, these civilizations should be in the process of rectifying the internal forces of civilization and reorganizing society, where they have time to visit here, could it be that they have encountered difficulties that cannot be solved?

"Let them come!"

The representatives of the six civilizations are coming, and it will take a while, so Li Yu continued to explain the problem of the space-time jump engine.

"Another thing that the space-time jump engine is extremely powerful, and that is that it can give us the opportunity to go deep into the black hole and study the black hole directly."

"It can't be, right!?" Everyone has an expression of Li Yu, you are lying to me.

Black holes, a celestial body, because of its strong gravitational pull, make people study it only from indirect research, and scientists on the earth have also put forward a lot of conjectures to study the internal situation of black holes, but none of them can seriously say that their own theories are correct.

The lab is also interested in the study of black holes, and many physical phenomena that are usually hidden outside of extreme environments may be easily presented in front of people's eyes, as long as you can observe them.

However, even with the level of science and technology in the laboratory, the study of black holes can only be distant.

Now Li Yu said that he can enter the inside of the black hole, which is an accident, of course, the black hole quotient that Li Yu said refers to the interior of the black hole's event horizon, because the black hole itself is a celestial body with a large mass limit and an infinitely small volume.

"Didn't I say that the plane-hopping engine can unify different planes. This function has no effect in a normal environment, but if the environment is replaced with a massive object such as a black hole, its utility is manifested. ”

"The closer you get to the black hole, the slower the passage of time, and unifying time means that a normal space-time region can be formed within the black hole horizon."

"I see, when are we going to investigate the inside of the black hole?" Lin Wanbai became interested.

"It's not possible for the time being, because we can't afford the energy expended to maintain normal space-time inside the black hole, and we may stay in it for a few seconds, and we will have to leave, or we may never be able to leave."

"If you say that, it doesn't make any sense to go inside a black hole." In a few seconds, what can you do, maybe even the instrument has just been turned on, and you have to leave, then entering the black hole is only for sightseeing, or luxury sightseeing.

"It can't be said that it doesn't make sense, isn't this also a way to find a way to get into the inside of a black hole? I believe that one day, we will be able to come and go freely inside the black hole. Fang Qianmo was not disappointed, since there is already a way, are you afraid that you will not be able to realize the situation of seeing black holes as nothing in the future?

With Li Yu's strength, it is not impossible that the other people in the laboratory have grown up to form the power.

"Although there is a wormhole, we can return to the Great Sky Region at any time, but how great would it be if the space-time jump engine could get us back to the galaxy all at once?" Sun Yixuan fantasized about having breakfast on the earth in the morning, and then going on an expedition hundreds of millions of years away from the earth, and returning to the earth to add a meal at noon.

"There will be such a day, now Li Yu can research a million-light-year engine, and I believe that when the engine is installed on our spacecraft, it will be possible to reach the level of tens of millions of light-years. Then there is not much to go from a billion-light-year engine! Lin Wanbai made a very arrogant statement, as if hundreds of millions of light years were in her eyes, that is, going out and slipping out of the circle.

"Li Yu, the representatives of those civilizations are here."

"Bring them here!"

Not long after, the same people who met Li Yu last time came to the bridge of the Space under the leadership of the robot.
