Chapter 262

"No! The way you said is too dangerous!" Xu zhe refused his request.

"What's the way?" Hao Zhi was still the most curious person after all, and couldn't help interrupting.

"Revise... History!" Lin Tao looked at the crowd and said firmly.

Modify history?

Everyone's eyes focused on Hao Zhi.

Lin Tao nodded: "it's not hard to understand. When we were in zone 51, we had a dialogue with the wise man EK. Do you remember? He said that when aliens invade the earth through billions of kilometers, they must first obtain some useful information about people on earth before they make this decision, otherwise no one will come rashly.

Therefore, we can learn from this that human beings leaked the biological information of the earth or human beings themselves. Hao Zhi has the ability to travel through time. As long as he returns to history and prevents us from publishing human information to outer space, he can establish a new historical node and completely change all the future from this historical node.

In other words, aliens do not know the existence of the earth, or know that the earth has life, but do not know whether the earth environment is the same as what they want. They will not easily invade us on a large scale.

It's like a person crossing the road with a friend. Because he pushed it jokingly, his friend fell into the road and was killed by a car. If he had the ability to go back to the past, he would not joke about it. Therefore, history was rewritten. When he returned to his own time period again, the future of his life was changed and his friend was still alive. "

"Childish!" Xu zhe said sternly. At the same time, he went to the desk and rang the bell called by the secretary. A little sweet voice came from the pager. What can I do for you?

Mr. Tom Burton, head of science and Technology Department, please come to my office!

Yes!

After a while, a white old man with silver hair knocked on the door and walked into the Fuehrer's office with a smile: "Sir, are you looking for me?"

Xu zhe nodded and then said to Lin Tao, "I don't understand science and technology, but I will also consult experts. You can listen to what the old man thinks of your plan!"

Obviously, Xu zhe had talked about this topic with Tom Burton before. The old scientist knew what was going on as soon as he heard it. He pushed his glasses on his face and calmly replied: "As a theoretical physicist, I appreciate your courage and courage to put forward such a grand plan. However, it is a pity that it does not conform to the common sense of physics we have. Fundamentally speaking, it is an impossible plan!"

"Why?"

Mr. Tom stated slowly: "Gentlemen, as we all know, relativity clearly points out that the speed of time passing is equal to the speed of light. The closer the speed of an object is to the speed of light, the slower the speed of time passing. When it reaches the speed of light, time stops. If it exceeds the speed of light, it is possible to turn back time and go back to the past... However, under the constraints of the basic laws of physics of our current universe, any object can It is impossible to exceed the upper limit of the speed of light. Therefore, since it is impossible to do so, it is a false proposition that does not exist at all. "

"Oh?" Lin Tao sneered, "what if someone has successfully returned to the past?"

"It's impossible!" the old scientist retorted in surprise.

"Hao Zhi..." Lin Tao pointed with his hand, "in order to save Wang Yanke, you once crossed the time and revised the history on the subway, didn't you?"

"But..." Hao Zhi hesitated, raised his hand and interrupted their argument. "There was once, but no matter who said it, right? Even if time travel was feasible, you told me that the past could not be changed!"

When he first saved Wang Yanke by changing the time, Lin Tao once told him that once history was formed, it could no longer be modified. It was like that Wang Yanke was shot and killed on the subway at 12 noon. Even if he returned to the past 11 o'clock to change the time of her death, as long as his memory had "Wang Yanke was killed at 12 o'clock" This confirmed future event will certainly happen, and the facts have proved that Wang Yanke didn't escape the disaster and was killed by the ghost in a slightly later period of time.

Later, he also gave up this attempt to rescue. The old Wang Yanke was indeed dead. This history has never changed.

"You saved me once with your ability? Why didn't you tell me?" Wang Yanke was surprised and asked Hao Zhi in a low voice.

"Ah? Ha ha, there's nothing to say... In fact, I didn't save you, but Lele blocked the shot on the subway for you..." Hao zhinao scratched his head and smiled.

On the other hand, old Mr. Burton hesitated: "There has been a theoretical basis for time travel before. We can make a simple example - suppose a person, let's call him No. 1, walks on the road on a bicycle, and there is the same cyclist No. 2 behind him. He rides his bike at a higher speed and goes in front of No. 1, then we can mark the time loss of this time period It is defined as three specific events, that is, first, it represents the time when the past No. 2 is behind No. 1, second, it represents the moment when the present No. 2 and No. 1 pass by, the time when the two people are in parallel, and third, it represents the time period when the future No. 2 is in front of No. 1.

And we can take No. 2 as the time when the speed of light runs. When its constant speed remains unchanged, if we want history to repeat itself, we must return to No. 1 in front of No. 2. Then, the only way is to increase the speed of No. 1. With 'now' as the coordinate origin, that is, when both sides walk side by side, only the speed of No. 1 increases to the speed of light, To keep moving forward together with No. 2, the parallel situation of the two people will be fixed, that is, the time will stop. If No. 1 surpasses No. 2 and returns to the front of No. 2, that is, the history repeats itself. Relatively speaking, No. 2 is riding slowly backward, and the position of No. 2 completely depends on the speed of No. 1 surpassing the speed of light. The more it surpasses the speed of light, The so-called 'past' that returned on the 2nd is farther back

However, it is a pity that the scientific theory we have so far does not allow any macro object to approach or reach the speed of light, let alone talk about surpassing the speed of light... "

"This is indeed true. The way the ghost taught me at that time was to rely on the brain wave to return to the past few seconds and control Lele's body. It can't be regarded as the real 'I' back to the past!" Hao Zhi suddenly remembered this.

Mr. Burton seemed proud that his theoretical conjecture had been confirmed, and pushed the thick lens on his face: "just a few seconds like a ghost's upper body is obviously not enough to change any historical node!"

Lin Tao shrugged helplessly: "I did say that at that time, but it was only limited to your personal brain wave. Under the action of your power, it strangely exceeded the speed of light and went back to the past. The change of this little microwave to the torrent of history should be extremely small. In fact, history is not immutable, but our interference with it is not large enough to affect its process!"

"The most dangerous thing is your idea! What you have to do this time is not just to send a brain wave information back, but to send a living person back to the historical node!" Xu Zheyuan said coldly, "Do you know what disastrous consequences this may bring? Is it necessary for all mankind to bear this unpredictable danger in order to help you redeem yourself?"

Atonement? Hao Zhi remembered in a trance that when he first talked to Lin Tao about aliens, he did call himself that he was a sinner of mankind and atoned for something.

"That's right! It was him who leaked the secrets of human genes to the blood moon man! He made this plan to modify history not only for the current plight of mankind, but also for correcting the mistake he made! So as to alleviate the heavy shackles he has been carrying for 20 years!" Xu Zhe scolded loudly.

Did Lin Tao reveal the secrets of mankind?

They were stunned and looked at him one after another. Lin Tao smiled: "Xu Zhe, I've known you for 20 years. In your eyes, I'll always be the sinner, and you are always too conceited!"

"Anyway, I won't allow you to risk the future of mankind. Your speculative idea will only drive all mankind to go to hell with you!" Xu zhe shouted at the door, "come on! Take him away!"

However, after stopping for a long time, there was no movement. Xu zhe vaguely felt something wrong. He suddenly jumped out of the back of the office and quickly pulled out a pistol from under the drawer. The muzzle of the pistol was just half raised, and a black gun had been put on his forehead first!

"Lin Tao! What do you want to do?" Xu zhe was not afraid, but asked loudly.

"I don't want to do anything. I'm here today, not to apply for you to pass my proposal, but to inform you that I want to implement the anti sky plan!" Lin Tao smiled and put his finger on the trigger.

"When I saw Hao Zhi and the battle cat regiment off at Lanzhou airport, I mentioned it to you once. Because the war was urgent at that time, I thought that after 20 years, you and I had reached a unity on the front. Who knows that you kept silent without hesitation until the end of the doomsday war. I mentioned this issue to you again. I sincerely hope to get you With your support, we are fully capable of saving the devastated earth. But you are indecisive. You think you are considering the so-called consequences of modifying history without authorization. In order to prevent me from finding Hao Zhi, you imprisoned me for more than half a year. Do you think I will give you another chance to lock me up? "

"You... How did you bring the gun here?" Xu Zhe, as the leader of the doomsday, the security work around him has always been rigorous. Even if Hao Zhi and Wang Yanke come to see him, they have to undergo a strict body search. Lin Tao can't pass the security check with a gun unless there is a traitor!

Before he finished asking, a tall and slim figure appeared at the door, wearing a straight military uniform, wearing a gray military cap, holding the same gun in his hand. He said apologetically, "I'm sorry, Fuehrer, I support general Lin Tao's decision for a reason!"

Everyone looked at Xu Zhe and was surprised to find that it was Zhang XURUI, Xu Zhe's closest Secretary! Zhang Dian
