"Are you sure I'm a traverser?"

Rootless duckweed did not reply directly, but asked rhetorically.

Isn't this obvious, Su Yuan smiled secretly and replied, "It depends on whether what you say next can make me believe it." ”

The other side was silent for a while, just when Su Yuan thought that he had to say something that interested her now, "Where are you now?"

The rootless duckweed spoke again, but it made Su Yuan's heart tighten.

"Why do you want to know where I am?" Su Yuanqiang suppressed the uneasiness in his heart and typed a few words into the screen.

Her intuition told her that the rootless duckweed would never ask her this question for no reason, but was there a deep meaning behind this? Thinking of this, she quickly asked Alayy, "Have you obtained the data information in the chat room?"

"Sorry, not yet, the other party's defense is very advanced, the time is too short, I can't distinguish the truth of the data......"

Alaya also behaved very anxiously, between the questions and answers with Su Yuan, the confrontation that happened in the network had been carried out countless rounds, a large amount of data was sent, but he never got the desired result, Rao is Alaya still has some reserve computing power that has not been used, and he knows that this time he has met an opponent.

"Don't rush, take your time. Su Yuan let out a long sigh.

She knew Alayah's computing power, and if Alayah was allowed to invade Adam and Eve in the United States, it would be a matter of minutes. But in the face of rootless duckweed, even Alayah can't overcome it, which shows how powerful the other party is!

It's a traverser from the future.

"Are you in Donghai Province?" said the rootless duckweed again.

Su Yuan felt a shock all over her body, and something called urgency suddenly enveloped her head.

This rootless duckweed actually knew that she was in Donghai Province, so didn't that mean that she was in a confrontation with him. At this moment, the prefabricated alarm in the computer room suddenly exploded. Alaya suddenly changed color and said, "Oh no, there's a huge stream of information rushing towards here. ”

"What?"

Su Yuan saw a hint of panic when he saw Alaya on the screen. Immediately after, a transparent shield suddenly appeared in front of Alayya's body, and outside the shield, a large area of red arrows continued to bombard the shield, hitting the transparent shield, causing ripples like rippling water.

Alaya stood still like a log, the floodgates of the reserve of computing power were opened, and suddenly a large amount of data was pushed back in the direction of the attack.

Through the three-dimensional animation, Su Yuan clearly saw the transition between attack and defense, and that's it. The tug-of-war between Alayah and rootless duckweed lasted for several minutes.

Eventually, with dozens of cabinets in the computer room running at full capacity, Alaya gradually shifted the scales back to the center, and then slowly moved in a favorable direction little by little. But no matter what the result is, Su Yuan's heart is full of horror, needless to say, the rootless duckweed has already taken actual actions to tell him the answer.

In the face of strength, any tongue is vain. Except for the explanation that the other party is a traverser, Su Yuan could not find any other reason to explain the technical means of rootless duckweed that far exceeded contemporary technology.

If it weren't for the "alien life" like Alayah. In the face of the attack of rootless duckweed, can she hold out in the hands of the opponent for a minute with only real materials?

There was almost no need to have any doubts, Su Yuan was 100% sure that he was just a stripped porcelain doll in front of the rootless duckweed.

"Do you think you can prove that I'm a time-traveler now?"

The words of rootless duckweed appear on the screen, and at the same time, the majestic torrent of data in the network is like a thunderstorm on a summer afternoon. It comes and goes as fast as it comes, and it disappears in the blink of an eye.

"You're very powerful!" Su Yuan admitted this sincerely, "Now I believe that you are also a traverser." ”

"Each other, each other. ”

Rootless duckweed said lightly. "I didn't believe in you 100% before, but through this temptation. Your computer skills are far ahead of my time, and I believe you. It seems that the strong have their own strong players, in my time. I'm known for my computer skills, and this time again, you're the second person who can push me back. ”

Su Yuan's face was hot when she said this, and at the same time, she was also curious about the words of the rootless duckweed, "Then what about the first person who can force you back?"

"My dad!" Rootless duckweed said bluntly, this answer almost made Su Yuan choke on his own saliva. "My dad was my mentor, and all my skills were taught by my dad. ”

"Well, another traverser, let's have an open conversation now. ”

After confirming each other's identities, rootless duckweed added a little more affection in their words.

Su Yuan didn't reply to him immediately, but asked Alayya, "Alaye, how was the result of the battle just now?"

Alaya said solemnly with a small face: "It's very dangerous, but fortunately, the other party is much inferior in terms of computing power, Alaya chased it out, but the other party was too cunning, and at the last moment, I don't know what method was used to block all the data, so Alaya can only judge that his host is also in Donghai Province!"

"Also in Donghai Province?" This answer was obviously beyond Su Yuan's expectations, "What about us, he attacked us just now, did our address be exposed to him?"

"Don't worry, the battle just now took place in the peripheral network, and Alayah tried his best to stop him, so this rootless duckweed can only know that we are in Donghai Province at most, just like we know that he is also in Donghai Province but we don't know which city it is, and he can't know that our real address is Haizhou. ”

"That's it......" Su Yuan's tense face finally relaxed.

After some fighting, Su Yuan had some understanding of the general situation: this rootless duckweed is very powerful, as he said...... In his time, his computer level was outstanding, and in this round of competition, the two traversers were of equal strength, and neither of them won a real victory, which also had certain benefits, so that the rootless duckweed did not dare to underestimate himself.

Alaye's existence is her strong confidence, thinking of this, Su Yuan smiled and said to the rootless duckweed: "Everyone is a traverser. It seems that we have more of a common topic, next. Let's talk openly and honestly......"

"Good!"

Rootless duckweed replied.

Su Yuan thought for a moment and tapped into the keyboard: "Then continue our topic in the forum." At that time, you came up with the concept of 'the long river of time', and described the long river of time as the invigilator who supervises all the special exams conducted in the universe at different times?"

"Yes, I think the long river of time is the key to achieving the world line jump!"

"But the crossing of the jumping worldline is actually a process of reducing entropy, and this process involves the need for an existence outside the system to provide the system with the energy needed to reduce entropy. But the question also comes, our big universe is so big that it may even be the whole world itself, if there is only one big universe, then how can there be a big universe outside the big universe?"

"You're right, jumping across the world line is a real step back in time. As long as it is going back in time, it will inevitably involve the problem of reducing entropy. In the same way, if it is impossible to find the existence that provides energy to the entire universe, the worldline jump cannot be completed. ”

Here's why a time machine that jumps across a world line is more difficult to build than a time machine that travels within a single world line!

The time machine shuttling within the world line is actually not a real time rewind, it goes back and forth, how the "script" should develop or how to develop, and the time travel is just to complete what should happen in the script. The world as a whole is still moving forward on the timeline, and the entropy has been increasing, not decreasing.

Jumping the world line is different, it is a process of "erasure-collapse". The whole world has really recoiled in the timeline, its entropy has decreased, and it needs majestic energy!

"Aren't we talking about how we can borrow a huge amount of energy from the river of time that reduces the entropy of the entire universe? In fact, this is not something that the traverser should consider at all, what the traverser should really consider is how to break free from the shackles of the original universe. Becoming the risk factor m identified by the invigilator, the rest is a matter of time? On the basis of the assumption that the time is the invigilator. Will the long river of time take the initiative to help the traverser complete the 'obliteration-collapse' of the world, so that the world line will jump?"

The rootless duckweed was silent for a while, and then said: "What you said is very reasonable, whether the second-generation time machine that can jump the world line can be made is the change of concept." When many people think of going back in time, they immediately think of the decrease in entropy, the decrease in entropy, and the need to provide enough energy to the system......

In the end, it was concluded that the source of the huge amount of energy could not be found, and that time reversal was unachievable! Of course, if the more cunning scientists are not willing to give up the fantasies of going back in time, they will wonder why our cosmic time is moving in the direction of increasing entropy, and why can't the positive direction of time be the direction of decreasing entropy?"

So they thought of a new world where the rules of physics were diametrically opposed to ours, and that there was another universe where the laws of time were reversed...... And if such a universe exists, the link between our universe and that universe is a thing where the rules of physics have collapsed, and the only thing that meets the requirements in the universe is black holes!"

Black holes are freaks of the universe, some people think they are stars, but they are so massive that even photons can't break free. A black hole has no size, but it has an event horizon, which is the limit of the black hole, at which an object needs to be as large as the speed of light to break free from its gravitational pull. And once inside the event horizon, photons can't break free, and photons are the fastest particles in our universe, so as long as all objects enter the event horizon, what awaits them will be the singularity that is compressed to the center of the black hole.

Some people also believe that black holes are not stars at all, but that they are subverted by the rules of physics in the universe.

Generally speaking, a star, such as the Earth, whose radius represents the spatial scale of the Earth, moves in the direction of increasing entropy on the time axis, which is applicable to all types of stars.

The only thing that is a black hole is that the internal time axis and the space axis are reversed, which means that the radius of the black hole represents the time axis, and the space axis is an abstract concept like the external time. (To be continued......)
