Similar situations are happening in Princeton, in Cambridge, in Moscow, at the University of Tokyo, and in universities and physics research institutes around the world, where they are either delighted, curious, skeptical, or disdainful at Lu Qiujian's article, some of them read it and throw it aside, and some of them try to use this model to study.

And Lu Qiujian did not stop there, a second related article is being written, this time he intends to conduct an in-depth analysis of this model, and deduce the phenomena that this model may produce in the experiment, in preparation for the official start of the experiment in the later stage.

"Hello Professor Dietrich!" "On this day, when the laboratory was not very busy, Lu Qiujian came to the observatory of the University of Munich to pay a visit to Professor Jörg Dietrich; since this expert in the field of dark matter had invited him before, it would be good to have more exchanges with him now, and it would always be good for more people to help him talk in the future.

"Oh, Lu, you're finally here!" Professor Dietrich was not polite, and directly pulled Lu Qiujian to his office, where a photo was plastered on the wall of his office. The photo shows a vast starry sky, and countless white, blue, and red spots of light are densely distributed on the bottomless black background, "Come and see this! This is what I told you last time!"

Professor Dietrich's obsessive look when he looked at this photo reminded Lu Qiujian of the otaku who watched Mr. Chen's photographic works, his eyes burning, as if he wanted to explore the ultimate mystery through all the obstructions on the photo.

Tsk, Lu Qiujian looked at the photo and smacked his tongue, such a large size, such a high pixel, just the photo paper has to be customized, and the cost spent on the photo paper is estimated to be six figures; It is necessary to have professional equipment, high-end specialists to carry out the rinse.

Professor Dietrich is really rich and capricious! But this thing is nothing compared to the telescope he uses or something, and it is really good to be a scientist! Think about it, those high-end devices that are hundreds of millions, billions, even billions, tens of billions of euros are like toys to them. What are the local tyrants in the Middle East who build golden sports cars?

"The blue part is the gravitational source depicted through gravitational lensing, and the red part is the intensity of the X-rays, which come from the radiation caused by the intense collision of plasma in galaxy clusters. Professor Dietrich explained to Lu Qiujian that the gravitational source of the blue part is dark matter, while the white part is the luminous star, and the orange part is the halo of the luminous star.

"Standing in front of this photo, human beings really seem small!" Lu Qiujian was also deeply impressed by the grandeur of this photo, which contains a cosmic scale in hundreds of millions of light-years, and these rays of light were captured by human beings after hundreds of millions of years after their birth.

"That's why I love astrophysics!" said Professor Dietrich. He gently stroked the surface of the photo, "There is no more beautiful picture in the world, compared to it, neither the Mona Lisa in the Louvre nor Marilyn Monroe in Eve Arnold's lens can make me look away for even a second!"

Hey, this Professor Dietrich must be single! Accustomed to seeing the grandeur and remoteness of the universe, deep and beautiful, and still having the heart to pay attention to the trivial things in life, Lu Qiujian only understood at this moment why Professor Schiff said that his temper was a little strange; it seems that he can orgasm without masturbating at this photo!

The materials that otaku masturbate are either hidden in their mobile phones. Either it's hidden in a folder on your computer called Joystick Driver or Mao Xuan, or it's replaced with a cover of teaching materials pressed under the pillow. How can there be such a bearing as Professor Dietrich sneakily, directly enlarged into dozens of square meters and pasted on the wall of his office openly!

Uh, but then again, it's not easy for otaku to find photos with such high-definition pixels! I'm afraid no teacher has ever taken such an awesome work, right?

"Look at this supercluster!" Professor Dietrich tried to reach out and pull Lu Qiujian over, but he subconsciously avoided it, who knows what he has in his hands! Fortunately, I saw that the secretary at the door just now seemed to have good personal hygiene habits, otherwise it would not be good if someone accidentally died.

"Are you talking about this?" Lu Qiujian followed him and walked two steps forward, looking at the red and blue star cluster that he was pointing at with his right index finger.

"Yes, that's it. "Superclusters are higher-order systems of galaxies that come together to form a system of objects that may span billions of light-years of space. More than 5% of the visible universe, the typical speed of galaxies is about 1000 km/s," the supercluster was named Abel 222/223. ”

"The red part should be X-rays emitted by the red-hot gas of a normal substance. "It looks like the red part is much smaller than the blue part.

"Well, after our calculations, normal matter is a component of the filaments of this supercluster, but it only accounts for 10% of its mass, and the rest is likely to be dark matter!" Professor Dietrich enthusiastically introduced the results of his team to Lu Qiujian, "We can see that there was a collision between these two galaxy clusters, and in the process of collision, the plasma interaction was so strong, but the two dark matter clusters did not interact with each other and passed through each other intact to the other side." This is very important observational evidence of the presence of dark matter in galaxy clusters and the separation of baryonic matter under violent impact. ”

"What a remarkable discovery!" exclaimed Lu Qiujian, who said that the fact that there was no dissipation was one of the characteristics of dark matter, and if two snowballs collided like these two star clusters, they might probably stick into a new big snowball.

Traditionally, dark matter has no interaction with each other other other than gravity, and when they meet, they do not stick together like two snowballs, but "penetrate" each other, and the kinetic energy does not dissipate. Because it does not dissipate, it is not possible for dark matter in the universe to continue to collapse until a relatively dense "dark matter star" is formed.

This model of the universe also explains the picture taken by Dietrice, which proves that dark matter is a fairly successful theory. (To be continued.) )
