Two flowers, one on each table.

Zao Wou-Ki was at the Flying Turtle to ensure its safety and completion, while the soldiers who were in their spare time were training to adapt to the new power armor as soon as possible so that they could meet the next challenges.

At this moment, Li Qianyang has a sad face, his hair is messy and obviously has not been cleaned for a long time, and there are stains such as milk, soup and even ink on the placket, but a pair of eyes are as bright as the sun, and in his hand is holding a stack of papers, which are full of all kinds of data and formulas, as for what is written on it, no one knows.

"Looking at you like this, there should be some answers."

Looking at this young student with old eyes, Shen Ningzhen suddenly felt relieved, and felt that the big stone in his heart had fallen.

"Yes, teacher. During these times, I have been observing the world, and although there are still problems with the specific mechanism of existence, some things have been thoroughly studied. Li Qianyang saw his teacher's excited expression, his eyes were a little dim, but he was thinking about whether he should hide some conjectures?

"What's that? Why don't you say it and let me help you refer to it? Shen Ningzhen immediately raised his curiosity and asked.

To be honest, since he saw the existence of this wormhole and the Yuan Spirit Realm, he has been painstakingly studying the reason why the composition of this world already exists, but he doesn't know whether it is because the concept in the past is too strong, or because he is too old, he has never understood the strangeness of this world, so after seeing Li Qianyang have the answer again, he actually has some joy.

If there is a breakthrough in theory, perhaps a new era will be ushered in for mankind.

With expectations for the future, Shen Ning really looked at Li Qianyang with some excitement.

Li Qianyang's fingers immediately clenched, and his joints turned white: "Teacher." I would like to ask. What do you know about dark matter? ”

"Dark matter?" Shen Ning chuckled in his heart, and suddenly felt a little dazed, "Are you saying that it only exists in inferences, but we have never observed dark matter from reality?" ”

"That's right, it's dark matter!" Taking a long breath, Li Qianyang said slowly. The sound is unusually heavy.

By the end of the 19th century, many physicists had begun to be convinced that the edifice of physics was completed, and that all that remained was some cosmetic work.

But those scientists, looking to the future of 20th-century physics, thoughtfully stated: "The theory of dynamics, which affirms that heat and light are two ways of motion, is now shrouded in two dark clouds over its beautiful, clear sky." ”

"The first dark cloud appeared on the wave theory of light,"

"The second dark cloud appears in the theory of thermodynamic statistical distribution of energy equalization."

The first dark cloud mainly refers to the contradiction between the results of the Michelson-Morey experiment and the theory of metamorphosis; The second dark cloud. It mainly refers to the fact that the energy equalization rule in thermal science has obtained unequal results from experiments in the theoretical interpretation of gas specific heat and thermal radiation energy spectrum, among which the "ultraviolet disaster" in the theory of blackbody radiation is the most prominent.

In the end, these two dark clouds led to the birth of two of the greatest theories of the twentieth century.

The emergence of quantum mechanics and the theory of relativity completely announced the end of classical physics, and directly opened the door for mankind to step into the next era.

But in the 21st century, the emergence of "dark matter" is like a nightmare haunting modern physics. And with its unique but mysterious characteristics, it has attracted many scientists to be fascinated. He is even obsessed with finding evidence of its existence and studying the principles of its formation.

Since the mid-80s of the last century, astronomers have gradually realized the shortcomings of the theory of relativity through the measurement and numerical simulation of the large-scale structure of the universe, the microwave radiation background, gravitational lensing, the Hubble constant, and the age of the universe.

When the "Big Bang" theory, which was deduced by the theory of relativity, was simulated by computers, it was found that in order to maintain the current state of the universe, the average density of matter must reach a negative 30 grams per cubic centimeter × 510. But. The density of the universe that has been observed, however, is 100 times smaller than this value.

In other words, most of the matter in the universe is "missing", and scientists call this "missing" matter "dark matter". 、

In the subsequent continuous observation, it was also discovered that supernovae and star clusters were different from the current model. In order to solve these problems, a large number of experimental observations and theoretical studies have been carried out, but the essence of dark energy is still foggy and hazy, and it is still one of the biggest confusions and challenges of modern physics and cosmology in this century.

If it can be analyzed, perhaps mankind will usher in a new era, just as the theory of relativity and quantum mechanics did.

"You mean to say that the world is dark matter?"

Removing the eyes above the bridge of his nose and wiping them gently, Shen Ningzhen suddenly felt an abnormal fear, remembering the starry sky he longed for when he was young.

The starry sky was so mysterious and profound, there were countless stars twinkling, and he even wondered if there were creatures like humans on those planets. But now, when he thinks of those distant spaces that shine with endless stars, he finds that what shrouds all this is a dark and cold black curtain.

Li Qianyang said: "Only this guess can match my speculation. ”

The sunken eyes were haggard, an image of long thought, but tiredness did not defeat him, but made his inky eyes glow like the sun, enough to illuminate the possible future.

Looking at his proudest disciple, Shen Ningzhen suddenly felt a little sad, what kind of suffering did this disciple of his go through during the long journey?

However, at this time, he also realized that pure persuasion was useless, so he had to give up the advice and express his conjecture: "But you should know that according to the inference of the WIMP model, dark matter does not appear in this way. ”

This is also the way of communication between the two of them.

Ask and answer, and constantly question each other to find out the possible direction.

"I know." Li Qianyang said: "Among the theories that explain the existence of dark matter, this is the most probable. Its official name is the massive weakly interacting particle. This is a hypothetical particle that interacts only through the weak nuclear force and gravity, or the interaction cross section of the particle is smaller than that of the weak nuclear force. Since they do not participate in electromagnetic forces, they cannot be directly detected; Since they do not participate in the action of strong nuclear forces, they basically do not interact with ordinary matter; Due to their large mass, they move relatively slowly, allowing them to gather in clumps. ”

Speaking of this, he paused, then strengthened his tone and said, "However, it is only hypothetical after all! ”

"That's right."

Shen Ning really sighed and felt a faint pain in his temples, the years of time had left too many imprints on his body, so that he would feel dizzy as long as he was a little excited, and his former proud Octavia thinking was also challenged: "Until it is verified, this theory is just a hypothesis. But, do you have any new theories? To unify the world with our world and even with dark matter, and in parallel with the theory of relativity and quantum mechanics? ”

When he saw the existence of wormholes and this world, he began this work.

However, the power of time is still too powerful after all, not only squeezing out the only life he has, but even the only thinking has been interrupted, Shen Ningzhen even feels that maybe in his lifetime, he will not be able to see the future world.

Even if it was a golden age for humanity to take off!

"I thought a lot, parallel worlds, multiverses, and finally suddenly I thought that maybe our universe is not homogeneous! Observation is too backward, and we are still too confined to the earth after all. Perhaps in other universes, there is a world that is diametrically opposed to our earth, a world in which physical constants are diametrically opposed. Its speed of light is variable, the force of gravity is not inversely proportional to the square of distance, and water is less dense than ice...... Perhaps, it is only under this premise that my theory can be formed. ”

Li Qianyang spoke slowly, probably because he still had some doubts about his theory, so his deep voice revealed a trace of confusion.

"Let's start by assuming a non-homogeneous universe. It's like a pizza, with a variety of fruits, vegetables, and even all kinds of meat sprinkled on top of a flatbread. These things make up what is known as dark matter, and they are based on some special mechanism that co-exists on a pizza. We're some fly that landed on it, and because we were so focused on the pie in front of us, we didn't find the ingredients at all. ”

"Of course, before this, we can find a slight difference between the taste in some areas and other places, a small change but obvious, and this subtle difference is noticed by us, although it feels strange and we don't know why, but since we haven't tasted more, that is, we have some doubts, so we don't pay attention to it, but continue to taste what is in our mouth."

"Then, out of the blue, we came to a diced potato bean and found that it tasted completely different. The previous pie was fluffy and delicious, but this one is a little hard and crispy, and it tastes completely different. At this time, we have to take a break from the concept in our minds and know that there is something completely different on this pizza than just those fluffy and delicious pies. ”

Speaking of this, Li Qianyang paused, his eyes staring at his mentor, lest what he published next would scare him: "Now, where I am, is a world that is surprising from the universe we observe. And it may be the legendary dark matter! (To be continued.) )

PS: I feel that plagiarism is not good, so I still revised it and let you understand better.
