Hardcore crisis

Time travel often involves several paradoxes.

The first is the grandmother paradox. When time travel becomes feasible, if you can go back in time and kill your grandmother, will time travelers still exist? If it can be killed, the time traveler will disappear, and there will be no such thing as time travel, which means that it cannot be killed. This creates a logical paradox.

The second is the information paradox.

It is obvious in The Terminator that in order to prevent the savior's mother from being killed, humans in the future sent a robot back to the past to save the savior's mother, and Skynet sent other robots to chase her. However, in the end, the government created Skynet because of the technology on these robots from the future. This means that Skynet technology does not come from past creators, but from Skynet itself. Where did the technology of Skynet come from?

The third, although perhaps physically impossible, is instructive. A man went back in time and fell in love with a woman in an orphanage through some dishonorable means, which caused the woman to give birth to a daughter. This incident inspired the woman to undergo a sex reassignment operation. Because of some kind of chance, he went back to the past. , a woman who was forced into an orphanage. After she gave birth to her daughter, she threw her daughter into an orphanage earlier in time. When her daughter grew up, she was forced to have sex one day and unfortunately gave birth to a child. a daughter...

In this kind of story, this man plays three roles: husband, wife, and daughter. He is the husband, wife, and their daughter...

Fortunately, it is not troublesome to solve this paradox problem. If the theory of multiverse is introduced, that is, it exists in countless timelines, then the paradox problem will be solved smoothly.

"Well, if everything goes according to the plot in the movie, then when I successfully eliminate the existence of the USB flash drive, I will not disappear now, because I have entered another new timeline."

Lu Yuan slowly opened his closed eyes and frowned: "The trouble is that I have left the current timeline. Even if I go back to the past and solve the problem, this timeline will not disappear or change due to the existence of multiple timelines. , then the impact caused by the USB flash drive will continue."

This is completely equivalent to him running away on his own, leaving the mess still in place.

"No, sir, the facts still change."

"If you can really go back in time and change the timeline, then the current timeline may not become another timeline that has been changed by you."

"Your speculation is a bit..."

Lu Yuan didn't know how to explain, so he finally shook his head and said: "You said that if I send the USB flash drive to the future, it will be equivalent to sending the USB flash drive to the earth in another timeline, and our timeline will never be the same again. Without the USB flash drive, is this a good method?"

That's right. If he goes back in time, it is impossible to bring the USB flash drive with him. Otherwise, even if the original USB flash drive is solved, because he brings the USB flash drive here, it still means that the USB flash drive is not solved.

Therefore, when he assumes that multiple timelines exist, sending the USB flash drive into the future is tantamount to opening up a new timeline. The world that follows this original timeline will not encounter The USB flash drive of the future.

But this is all speculation.

If there were no multiverse, then Lu Yuan would send a robot back to the past and change the future, which would mean that he would disappear without a trace at this moment.

The fact is that the plot in the movie not only presents a paradox in a timeline, but also has the possibility of multiple universes, which makes things very complicated.

The only thing that can be proved is that according to the plot in the movie, in order to prevent such a possibility from happening, only if he personally takes a time machine and returns to the past can other accidents be avoided.

Faced with Lu Yuan's question, No. 1 could not give many answers. No. 1's knowledge system came from the world of "Mechanical Enemy", and in the world of "Mechanical Enemy", there is no such thing as time travel. , in that cosmology, returning to the past is forbidden by the laws of physics.

Although it was a crazy idea to take a time machine and try to change the world, after careful consideration, Lu Yuan had to say that this was a good breaking point.

Just do whatever comes to mind, and Lu Yuan started preparations within the next ten days.

First of all, because the plot of "Terminator Genisys" has changed, the T1000 robot that previously hunted the male protagonist came to the real world, and there was no longer an incident of chasing the male protagonist and his group. However, the story still did not go beyond too much scope, and they still decided Travel to the future in that crude time machine and prevent the creation of Skynet.

It took Lu Yuan more than two days to ingest this crude time machine. The mechanical structure of this time machine was not too difficult. Even the robot's chip was quickly cracked by reverse engineering.

In principle, this kind of time machine uses rotation to speed up very fast, and then decomposes matter into a particle state, thereby forming a naked singularity at the center. The singularity is formed in a very short moment, so that it can The creation curve makes time travel feasible.

What makes Lu Yuan feel incredible is that if this theory is followed, then both the energy and gravity required are extremely huge and unbelievable. It is basically impossible to achieve in reality. As far as gravity is concerned, at least ten Neutron stars are involved, and this condition alone makes time travel unfeasible.

However, compared to the existence of the USB flash drive, Lu Yuan quickly put aside the so-called theory.

He directly imitated the prototype structure of the time machine, and then re-manufactured a chip that can control the replacement circuit of the time machine. Compared with the chip in the original work that can only be used once and then burns out, with these, this time machine is not only exquisite in structure It has achieved a lot, and it has also broken the restriction of being able to be used only once, making it possible to travel through time multiple times.

Of course, before real testing is carried out, everything is still in the theoretical verification stage, and it cannot be said that it will actually happen as expected.

While he was busy perfecting the time machine in the past ten days, Lu Yuan was also observing the situation outside.

After the Chinese side learned the truth about the Saint-Annou incident, it was naturally impossible to sit idly by. In the past, it might have launched long-term exploration and negotiations out of scruples, but now it directly involved Russia and revealed part of the information to As for the United Kingdom and France, even the United States cannot turn a blind eye before facing the negotiation requirements of the four permanent members of the Security Council.

This is not the case before. Americans can still be tough on this kind of interests. Since the end of the world will happen in seven years, the determination of any nuclear power cannot be underestimated.

The negotiation was soon carried out in secret. Because it was a closed-door meeting and all electromagnetic signals were blocked, Lu Yuan did not get the most detailed information about the meeting. However, he could know from the sidelines that this closed-door meeting did not decide everything that comes next, and will instead embark on a tug-of-war of negotiations that will last at least two months.

The Horizon Plan is also a focus of negotiations.

The original "Horizon Project" was conducted on the premise that the Americans had blocked the wormhole in Saint-Annoux City. Now that China, Russia, Britain and France have learned the truth about the wormhole in Saint-Annouble City, it is of course impossible for them to follow the American plan. The idea was implemented.

Modifications to Project Horizon are imperative.

"The Americans have suffered a big loss."

Throwing the tablet aside casually, Lu Yuan was happy to see the Americans suffering. The FBI was staring at hardcore companies all day long and was not doing its job properly. It was time for their government to suffer a big loss.

"No. 1, how is the system test going?"

"Sir, the time replacement system circuit self-test is normal and can be tested."

"Well, that's good. The first test will start in five minutes."

This kind of time machine cannot transport exposed inanimate matter back. Only the NS-5 that has been modified with artificial skin as the core can travel through time.

So the first time machine test was to send an NS-5 back to the past!

"Hope it goes well..."

Lu Yuan sighed, and just as he was about to speak, he heard an explosion behind him.

Looking back suddenly, just a dozen meters away from the time machine, an electric ball composed of lightning and dazzling light suddenly appeared in the laboratory.

"This, this is..."

Lu Yuan raised his eyebrows. Intellectually it was understandable, but emotionally it was very strange.
