Similar situations are happening in Princeton, Cambridge, Moscow, Dongda University, and in various universities and physics research institutions around the world. They are either happy, curious, doubtful, or looking at Lu Qiujian’s words with disdain.

Some articles were thrown aside after reading, while others tried to use this model to study. Please search for the most complete novels!

Lu Qiujian did not stop here. The second related article is being written. This time he plans to conduct an in-depth analysis of this model and deduce the phenomena that may occur during the test, so as to prepare for the official start of the experiment later.

Make preparations.

"Hello, Professor Dietrich!" Taking advantage of the fact that the laboratory was not very busy that day, Lu Qiujian came to the Observatory of the University of Munich to visit Professor Jörg Dietrich; since this expert in the field of dark matter had visited him before

Since you have sent out an invitation, you might as well communicate more with him now that you have time. It will always be good to have more people help you speak in the future.

"Oh, Lu, you're finally here!" Professor Dietrich did not show any politeness and directly pulled Lu Qiujian to his office. On the wall of his office was a photo as big as the wall. On the photo

It is a vast starry sky, with countless white, blue and red spots densely distributed on the bottomless black background. "Come and look at this! This is the discovery I told you last time!"

"

The obsessed look in Professor Dietrich's eyes when he looked at this photo reminded Lu Qiujian of the otaku who looked at Teacher Chen's photography. His eyes were burning, as if he wanted to see through all the obstructions in the photo, just to explore the ultimate mystery.

The latest chapter of пge has been updated

Tsk tsk, Lu Qiujian looked at the photo and clicked his tongue. With such a large size and such high pixels, the photo paper alone had to be specially customized. The cost of the photo paper is estimated to be six figures; the development work

It is not something that ordinary people can do. It requires professional equipment and high-end experts to perform the cleaning.

Professor Dietrich is really rich and willful! But this thing is nothing compared to the telescope he uses. It is really good to be a scientist! Think about it, those hundreds of millions, more than ten

High-end equipment worth billions, or even billions, or tens of billions of euros is like toys to them. Compared with these, what do the tycoons in the Middle East who build golden sports cars count?

"The blue part is the gravitational source depicted through gravitational lensing; the red part is the intensity of the rays, which originate from the radiation caused by strong collisions of plasmas in galaxy clusters." Professor Dietrich explained to Lu Qiujian, the blue part

Part of the gravitational source is dark matter, 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 look insignificant!" Lu Qiujian was also deeply dazzled by the magnificence of this photo. A square inch contains the scale of the universe measured in billions of light-years. These light rays

It took hundreds of millions of years after its birth to be captured by humans; compared to this, the time it took for humans to be born is nothing!

"This is why I love astrophysics!" Professor Dietrich deeply agreed with his words. He gently stroked the surface of the photo. "There is no more beautiful picture in the world than this. Compared with it,

, neither the "Mona Lisa" in the Louvre nor Marilyn Monroe in Eve Arnold's lens can make me look away even for a second!"

Hey, this Professor Dietrich must be single! He is used to seeing the grandeur, distance, depth and beauty of the universe, so he still has the time to care about the trivial things in life. Only now did Lu Qiujian understand why Professor Schftt said that he

His temper is a bit weird; it seems like he can get aroused in front of this picture without masturbating!

The materials for otakus to masturbate are either hidden in their mobile phones, or hidden in a folder on their computer named Joystick Driver or Mao Xuan, or they are replaced with the cover of educational materials and pressed under the pillow. How sneaky are they?

With Professor Dietrich’s magnanimity, he directly enlarged it to dozens of square meters and posted it on the wall of his office openly!

Um, but then again, it’s not easy for otakus to find photos with such high-definition pixels! I’m afraid no teacher with both virtue and skill has ever taken such awesome works?

"Come and see this super galaxy cluster!" Professor Dietrich tried to reach out and pull Lu Qiujian over, but he subconsciously avoided it. Who knows what he had in his hands! Well, luckily I saw the man at the door just now.

The secretary seems to have good personal hygiene habits, otherwise someone would be killed accidentally.

"Is that what you're talking about?" Lu Qiujian followed him and took two steps forward, looking at the star cluster shrouded in red and blue that he was pointing with his right index finger.

"Yes, that's it." A supercluster is a higher-level celestial system composed of several galaxy clusters. They may span billions of light-years of space, accounting for more than 5% of the visible universe. They are typical of galaxies.

With a speed of about 1,000 kilometers per second, "this supercluster is named Abel 222/2."

"The red part should be the rays emitted by the hot gas of normal matter." It seems that the area of ​​the red part is much smaller than the blue part.

"Hmm, after our calculations, normal matter is a component of the supercluster's filaments, but it only accounts for 10% of its mass. The remaining part is likely to be dark matter!" Professor Dietrich said enthusiastically

Xiang Lu Qiujian introduced the results of his team, "We can see that what happened between the two galaxy clusters

Collision. During the collision, the plasma interaction was so strong, but the two masses of dark matter had no obvious interaction and passed through each other intact to the other side. This is a very important dark matter that exists in galaxy clusters.

, and observational evidence of separation from baryonic matter under violent impact."

"A very remarkable discovery!" Lu Qiujian exclaimed. Collision without dissipation is one of the characteristics of dark matter. If two snowballs collide like these two star clusters, they may stick together to form a new one.

Big snowball.

But dark matter is different. According to the traditional view, there is no other interaction between dark matter except gravity. When they meet, they will not stick together like two snowballs, but will "penetrate" each other, and their kinetic energy will not

Dissipation occurs. Because it does not dissipate, it is impossible for the dark matter in the universe to continue to collapse until a relatively dense "dark matter star" is formed.

This cosmological model also explains the photo taken by Dietrich very well, proving that dark matter is a quite successful theory.)
