Lu Ming saw that researcher Hu Xiaozheng in front of him was obviously stunned, as if he didn't understand, and repeated the word: "Future? ”

"Yes." Lu Ming said: "Just like the explanation of the virtual particle pair, it is actually similar to 'the world outside the black hole 'borrowing' mass from the black hole, is it possible that this abnormally increased mass has 'borrowed' mass from the future?" The conventional theory is that black holes are just in and out.

Because the event horizon, the edge of the black hole, where the gravitational pull of the black hole is so strong that it escapes faster than the speed of light.

And the speed of light is the upper limit of speed in the universe. No mass object can move at the speed of light, let alone exceed it.

Among some of Lu Ming's previous cases, he highly suspected that he had experienced faster-than-light travel. But he and the scientists in the research department all believe that it is through some kind of mechanism.

"Bypassing" the limits of the upper limit of the speed of light. In other words, although it is true that there is faster-than-light travel, the upper limit of the speed of light still exists.

Based on this, the traditional theory is that black holes can only be released. But this violates the rest of the laws of physics, such as the law of blackbody radiation.

The smaller the black hole, the hotter it is. There must be black holes in the universe whose temperature exceeds the temperature of the cosmic background radiation.

The law of black-body radiation states that temperature must be transferred from high to low, and that a black hole with a higher temperature must also radiate energy into space.

But don't black holes just go in and out? If you only go in and can't go out, how can you radiate energy? A scientist named Stephen Hawking eventually developed a set of names called

The theory of "Hawking radiation". He believes that black holes can radiate energy to the outside world through the process of Hawking radiation.

This involves the pair of virtual particles that fluctuate and fall from the vacuum. Where the virtual particles are opposed

"Virtual" is because it actually does not exist, and the Dharma is observed by people - people can only observe real particles, so once virtual particles are observed, they are no longer virtual particles.

And the reason why you have to figure it out

The concept of "virtual particle pairs" is mathematically necessary. In the mathematical process, it is very useful to carry out relevant calculations according to the concept of virtual particles, so it is customary to use virtual particle pairs to describe the process.

There are two particles in a virtual particle pair, one with a positive mass and one with a negative mass. Around the black hole, virtual particles with negative mass fall into the black hole, which causes the mass of the black hole to decrease.

When a virtual particle with negative mass falls into a black hole, the virtual particle with positive mass will turn from virtual to solid and become an observable particle and escape outward.

From this, it is created

The phenomenon of "black holes also radiate energy outward" not only satisfies the law of black-body radiation, but also does not violate it

The identification of "black holes only enter but cannot leave". - Nothing comes out of the black hole, it's just that particles with negative mass fall into the black hole.

But this process, in essence, is

"The outside world 'borrows' a part of the mass from the black hole through a certain process." From this, Lu Ming had a guess.

If a part of the mass of the black hole can be borrowed from the outside world through some mechanism, then is it possible that there is also a mechanism that can be present and future?

"Borrowing" a part of the mass? Researcher Hu Xiaozheng thought for a moment and smiled: "Well, it's a very interesting conjecture. Some theories of quantum gravity also speculate that time may be discontinuous, or even quantum, i.e., it is possible for us to have some theory to describe the physical properties of such 'time particles' and predict their behavior, and even to influence and change them by some means. In addition, black holes are the most mysterious and strange celestial bodies in the universe, and we currently have no theory that can cover the environment inside black holes. In this case, it is possible to guess it. Lu Ming nodded.

Researcher Hu Xiaozheng then spread his hands: "But it has no value. ”

"No value?"

"Yes." Researcher Hu Xiaozheng did not show mercy to Lu Ming: "I don't know how many wonderful ideas about physics appear in the world every day. I have to admit that many of these ideas are possible. But...... We can't verify it. The development of experimental physics is too backward to keep up with the progress of theoretical physics, and it is impossible to verify it in the foreseeable future. Just like Superstring Theory, some of the speculations in it, if we want to verify it, we can't increase the energy of the existing particle collider by a factor of 100 to meet the requirements of the verification environment. There are so many ideas, and your guess is just one of them. What value do you say it's worth? Lu Ming thought for a while and nodded in agreement: "That's true." In general, my conjecture is that there is a certain possibility, but it is impossible to prove or falsify'. ”

"Yes. However, if we continue to extend this conjecture, it is quite interesting. Researcher Hu Xiaozheng said with great interest: "If this conjecture is true, then first of all, the particles of the future, or energy, have been 'borrowed' to the present, then it seems to mean that the phenomenon of going back in time has occurred." This is contrary to the existing theory. However, the possibility of time reversal at the micro level has not been completely denied...... "Lu Ming knows that in fact, the existing physical theories and the bottom layer of science have not determined the time method of time reversal.

It's like two small balls colliding and then bouncing off – the process follows the laws of physics exactly. But if this process is filmed and then played backwards, that is, the process is reversed, then the reverse process also follows the laws of physics, and there is no violation in the slightest.

Physical theory does not say that going back in time is not feasible. What thinks that it is not possible to turn back time is actually the law of thermodynamics.

Thermodynamics involves statistical mechanics, which is a theory at a more macroscopic level. But...... It does not dismiss the possibility of a time reversal phenomenon at the micro level.

Hu Xiaozheng thought about it and continued to say slowly: "However, particles return to the present from the future, and it also involves the interpretation of multiple universes, which is even more complicated...... There are too many preconditions involved in this explanation, and the probability of being true is very low. "To agree with this conjecture, we must first confirm that the phenomenon of time reversal in the microscopic world really exists, that the multiverse interpretation is true, and that some of the rest of the conjectures are true, and that the conjecture that particles return from the future to the present can only be true.

This significantly reduces the likelihood of this conjecture. After all, the probability of a bomb on an airplane is assumed to be 1 in 2 million, and the probability of two bombs is reduced to 1 in 2 million squared, which is only 1 in 4 trillion.

- That's what the famous one is

"How can I reduce the probability of a bomb on my plane when I am on an airplane? Answer: You bring a bomb on the plane first" is the source of the joke.

Returning to the conjecture at this moment, assuming that the probability of the microscopic time reversal phenomenon does exist is 1 in 1,000, and the probability of the multiverse interpretation being true is also 1 in 1,000, and after both conjectures are true,

The conjecture that "particles return from the future to the present" can be true, and the probability of its validity plummeting to less than one in a million.

"The conjecture that the present borrows a part of its mass from the future, in addition to the fact that the future world will go back in time, and particles will return from the future to the present, there may be another explanation." Lu Ming said: "Fate? ”

"You mean ......"

"Suppose that we have borrowed a part of the mass from the future, which leads to the phenomenon of abnormal mass increase in the experiment at this moment, but in fact, there is no future world at this moment, and it only determines a kind of fate: at some time in the future, a part of the mass will definitely disappear out of thin air. In this way, as a whole, mass and energy are still conserved. The difference is only in the space of the rest of the particles that transmit the force, and in the time of the particles that transmit the force. Researcher Hu Xiaozheng scratched his head: "Rice atoms constitute matter, and bosons transmit force, so this conjecture seems to confirm that time has quantum?" And the particle of time is a boson? This, this...... Well, that's interesting. He could only say one thing that was very interesting.

After all, there is no way to verify it.

"But...... I have a new idea. Hu Xiaozheng's body sat up straight again: "This kind of fatalism and other expressions are likely to be contrary to the principle of inaccuracy." After all, the bottom of the universe is random, and what the future will develop into is theoretically unpredictable. I have a conjecture that does not contradict the principle of uncertainty. Is it possible that the fate of 'an abnormal increase in mass at this moment, which determines that a part of the mass must disappear out of thin air in the future', only determines this fate, but does not determine the specific way to 'realize' this fate? Like, the quality that we have added at the moment, borrowed from the future, after a certain period of time, after the future comes, the part of the quality that disappears out of thin air may come from you, or from me, from this table, from this floor, from this wall...... We can't predict where it came from, we won't know until a series of random processes take place. In this way, it is not contrary to the principle of inaccuracy, and the possibility of establishment is greatly increased. Lu Ming nodded thoughtfully.

Suddenly, he reluctantly raised his head and stared straight at Hu Xiaozheng, his eyes full of shock and a little ...... Joy.

He seemed to have something in mind. Hu Xiaozheng is a little inexplicable. He touched his face suspiciously, and after confirming that there was no rice or anything like that on it, he asked, "Sergeant Lu?" What happened to you? Lu Ming woke up from his contemplation.

He let out a long sigh and stood up.

"Thank you, Professor Hu. Your conjecture is very enlightening to me. I was very rewarding. Hu Xiaozheng sneered: "Oh, is it? "He didn't know what he was talking about, what he was doing.

Isn't this just random chatting and guessing? This thing can also be useful? Lu Ming stretched out his hand and solemnly shook hands with Hu Xiaozheng: "Yes." There is a lot of use. That's it for today, and when I have time, I look forward to talking to you about these conjectures again. After saying goodbye, Lu Ming turned around and left.

"Wait!" Hu Xiaozheng stood up and stopped Lu Ming. Lu Ming turned his head and waited for his words.

But when he saw Hu Xiaozheng snorting, his face was red, and he wanted to say something, but he couldn't say it. Eventually, he sighed and said, "Uh, it's okay, then, goodbye." Lu Ming was a little funny in his heart.

He knew that Hu Xiaozheng must have wanted to ask him what the use of those previous conjectures was, but limited to the confidentiality regulations, he knew that he would definitely refuse him, and it was not suitable for him to ask, so he could only hold back this curiosity.

Lu Ming could see that this Hu Xiaozheng was a very curious person. With this question in his heart, I am afraid that he will not be able to sleep well in the next few days.

Lu Ming felt a little guilty. After thinking about it, he said, "Professor Hu, is there anything missing from your research?" equipment, warps and the like. Yes, we have a budget for the security department this year, and I can try to apply for it, and if I can get it, I can sponsor your research. It's not much, but it's a little bit of our heart. Hearing that there was a sponsorship to take, Hu Xiaozheng really perked up, and the curiosity he had before immediately disappeared: "If there is sponsorship, it will help me a lot." Sergeant Lu, you may not know, these days, the most lacking thing is our kind of basic physics research......" Lu Ming laughed in his heart.

What discipline can be like basic physics research, where it has to embark on a big project at every turn, and it takes tens of billions or hundreds of billions of dollars to build a particle collider?

If research is really opened, the GDP of all mankind will not be enough, can there be no shortage of experience? Of course, the sponsorship that Lu Ming promised was only hundreds of thousands at most, and it could not be too much.

With this amount of money, you can't do big things, but small things, such as holding a seminar, reimbursing point travel, etc., can.

The second team of operations can still get it.

"Someone will contact you in the future to confirm the sponsorship."

"Ahh Hu Xiaozheng was full of gratitude. The more things you can do are that you can get sponsorship by chatting casually and guessing something, the better.

Leaving the particle collision laboratory, Lu Ming did not rush back, but dialed Lu Qingliang's phone again.

After first suing Lu Qingliang about the sponsorship and asking him to handle it specifically, Lu Ming said: "Help me contact the 'Black Hole Hunter' organization, I have some things that they need to do." And...... We may have to get another sponsorship, maybe quite a bit. You are mentally prepared. I'll report to the captain, you'll have to report to Li if necessary. ”
