"Time travel is such a thing, as long as you know what the theory is, it is the same thing!" In the shelter of the Ain, Li Yu's face was indifferent when he said this, and he deliberately ignored the strange looks on the faces of others. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Li Yu had already written out the theory of time and space that he had studied, and Fang Qianmo and the others were reading his masterpiece. If Li Yu's research results are expressed in a formula, it is the same as the mass-energy formula, which is very concise, which makes people wonder whether Li Yu has developed a false space-time theory.

Energy is equal to mass multiplied by the speed of light squared, which is the mass-energy formula. Li Yu's space-time energy formula introduces the variable of time into the mass-energy formula, and space-time is equal to energy multiplied by time.

On the time axis of physics, time represents a continuous interval of time, and two time intervals represent a period of time, which corresponds to a period of time on the time axis. Whereas, a moment refers to a certain moment, which corresponds to a point in time coordinates.

The above concepts are appropriate in non-relativistic situations.

The time introduced by Li Yu is a vector. Generally speaking, time is a scalar quantity, only by magnitude, without direction. But in high-dimensional space-time, time is just a component of a vector. So time should be a vector relative to the universe as a whole.

It is also said that there is a vector time, which is decomposed into scalar time under different circumstances.

After the introduction of vector time, the mass-energy formula undergoes a series of transformations to finally become the space-time formula.

In this formula, time is a vector, and of course there is a direction, and time and space travel has a theoretical basis. However, time travel is a mistake for the universe and needs to be corrected.

In three-dimensional space, the time component is a scalar quantity, always moving forward and not backward. What kind of power is time? In the past, time has propelled everything in the universe to change into the present, and the present is also the future under the influence of time.

If you want to study Li Yu's theory of time and space, it is obviously not possible to get any results in a while, so Fang Qianmo and the others pulled Li Yu to discuss, at least if they encounter problems, Li Yu can answer them at any time.

"Li Yu, let's not talk about this formula first, let's talk about how to open the space-time point first?" Lin Wanbai couldn't wait to ask questions, among the people present, her mathematical attainments were the highest, so she also had the most questions.

"First of all, you must be clear about one thing, in the space-time formula, time is a vector, and then you can understand the following things."

Li Yu organized the language first, so that the next words, whether it was Fang Qianmo or Sun Yixuan, could be understood.

"Since time is a vector, you can go back in time. To go back in time, then it is enough to apply a space-time in the opposite direction to space-time. ”

"Energy is a scalar quantity, so space-time is a vector. To be anti-space-time is to be anti-space. So we're going to go back in time, just create an anti-space, and that's it. ”

"Anti-space? Is there such a space? The lab hadn't discovered the existence of antispace before. After Fang Qianmo finished speaking, the existence of antimatter suddenly arose, so he continued without waiting for Li Yu's question and answer: "Antispace is actually a space composed of antimatter!" ”

"That's right!" Li Yu affirmed Fang Qianmo's conjecture.

"But we haven't ever discovered the existence of antimatter space!" Although Fang Qianmo guessed, he didn't think that the antimatter space could exist in that dimension.

Lin Wanbai heard this, and said faintly: "In fact, antimatter space does not exist at all in the real universe!" I'm right, it's just a mathematically space! ”

Li Yu listened to Lin Wanbai's words, nodded his head and said, "Wanbai, what you said is neither right nor right!" Of course, there is no antimatter space in the real universe, and if it exists, it will not be messed up? ”

"Scientists on Earth have discovered that when antimatter meets positive matter, it will annihilate the generated energy, which is extremely large, comparable to our dark energy reactors."

"What Wanbai said is wrong is that the antimatter space actually existed in the past space-time."

What Li Yu said, other people actually didn't understand it, how could antimatter space exist in the past time and space? However, it doesn't matter if you can't understand it for the time being, let's listen to what Li Yu said next.

"Antimatter space exists in the past space-time, and it is the key to our ability to return to the past. I know you don't understand it for now, but it's okay, let's make a hypothesis first. ”

"Assuming that antimatter space existed in the past space-time, then it would be much easier for us to go back to the past. We create an antimatter space, let this space generate energy, resonate with the past space-time antimatter space, and then open up space-time points. ”

"The advantage of this is that it is extremely energy-efficient. Compared with the previous theory, which requires the energy of the entire universe to open a space-time point, it can be said that it is too much and too much, and it can be simply described as effortless. ”

Speaking of which, Li Yu has already formed a complete theory and process on how to open the time and space points, and Fang Qianmo and the others can only obey.

It's just that there is another question in the middle, "Li Yu, when antimatter meets positive matter, it will be annihilated, right?" "Sun Yixuan also heard the concept of antimatter when she was on Earth.

"Is this it? In fact, antimatter is not so simple. Due to the lack of science and technology on the earth, it is extremely difficult to produce antimatter, so geoscientists do not have a deep understanding of antimatter. ”

"It should be noted that the energy that opens the point of space-time cannot be the energy produced by the annihilation of antimatter and positive matter! This kind of energy can't open the space-time point, only the energy generated before the antimatter can open the space-time point? ”

Li Yu added this point, even Fang Qianmo didn't expect it, only Lin Wanbai vaguely felt that there was a problem at that time, but he couldn't find it, and when Li Yu pointed out the problem, they found out that there was still a problem here!

"Of course, if only the energy generated by the annihilation of positive and antimatter can open the point of space-time, what else do we need antimatter for? Can our dark energy reactors provide this energy? ”

Li Yu's words opened a new door for Fang Qianmo and them.

The laboratory's research on antimatter is actually not too advanced compared to the earth, mainly because Li Yu did not pay attention to this aspect, which is the shortcoming of the laboratory that was too high at first.

The starting point is the research space, so it is natural to look down on antimatter, antimatter is not easy to preserve, and the energy provided is not unique compared to dark energy reactors, and it should be studied without in-depth research.

Anti-energy, which is the energy produced by antimatter. For example, hydrogen can produce a nuclear fusion reaction that releases a large amount of energy. Then the anti-hydrogen element can also carry out a nuclear fusion reaction to produce a large amount of energy, and this energy is the anti-energy.

Energy is a scalar quantity, there is no direction, and the positive and negative of the energy are just different in nature.

Only anti-energy can easily break the barriers of time and space.

Now, everyone has figured out the principle of the generation of space-time points.

"Li Yu, time is a vector in the space-time formula, what else exists besides the past space-time? There aren't just two directions for vector time, right? Lin Wanbai pondered another question.

"Of course, in addition to going back to the past, you can also create a parallel universe!" Li Yu gave an example, Lin Wanbai's eyes lit up when he heard this, and it was really glowing.

This made Li Yu have to worry about what was wrong with Lin Wanbai: "Wanbai, are you okay?" ”

Lin Wanbai fell into a certain thought, and didn't hear Li Yu's words at all, Fang Qianmo on the side explained to Li Yu with a smile: "She saw that other people's eyes can emit light without moving, and she thinks this is very imposing, so she also drums out the function!" ”

I see, there is nothing to worry about, if Lin Wanbai planted a flower on his head that day, Li Yu would not be surprised, but Li Yu didn't expect that Lin Wanbai would really be inspired by Anna one day in the future, and a flower would also grow on his head.
