Demon School

Similar situations have happened in Princeton, Cambridge, Moscow, Dongda University, various universities and physics research institutions in the world. They are either happy, curious, skeptical, or looking at Lu Qiujian disdainfully. Some articles were thrown aside after reading, while others tried to study this model. △ ↗

And Lu Qiujian did not stop there. The second related article is being written. This time he intends to conduct an in-depth analysis of this model and derive the phenomena that this model may produce in the experiment. prepare for.

"Hello Professor Dietrich!" Lü Qiujian came to the Observatory of the University of Munich to pay a visit to Professor Jörg Dietrich while the laboratory was not very busy this day; since this expert in the field of dark matter An invitation has been sent, so now you may have time to have more exchanges with him, and it is always good for multiple people to help themselves in the future.

"Oh, Lu, you are finally here!" Professor Dietrich did not politely pull Lu Qiujian directly to his office, and a large photo of the wall was posted on the wall of his office. The photo is a vast starry sky, and there are countless white, blue, and red spots scattered on the deep black background. "Look at this! This is what I told you last time. Find!"

Professor Dietrich's obsessive eyes when looking at this photo reminded Lu Qiujian of the otaku who watched Mr. Chen's photographs. His eyes were burning, and he seemed to go through all the occlusions in the photos, just to explore the ultimate secret.

Gee, Lu Qiujian looked at the photos for a while, such a large size, such high pixels, only the photo paper had to be specially customized, the cost spent on the photo paper is estimated to be six digits; Nor is it possible for ordinary people. Must have professional equipment, high-end experts to specialize in washing.

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

"The blue part is the gravitational source depicted by the gravitational lens; the red part is the intensity of the x-rays, which originate from the radiation caused by the intense collision of the plasma in the galaxy cluster." Professor Dietrich explained to Lu Qiujian, The gravitational source of the blue part is dark matter, and the white part is the glowing star, and the orange part is the halo of the glowing star.

"Standing in front of this picture, humans are really small!" Lu Qiujian was deeply smitten by the magnificence of this picture, and the squares contained the cosmic scale in billions of light years. It took hundreds of millions of years after the birth to be captured by human beings; compared to this, what time is this human being born!

"This is why I love astronomy!" Professor Dietrich strongly agreed with his words. He gently touched the surface of the photo. "There is no better picture in the world than this, whether it is" Mona Lisa "in the Louvre or Mary in the lens of Eve-Arnold. Lian-Monroe can't make me look away even for a second! "

Hey, this Professor Dietrich must be single! Seeing the magnificence of the universe, the beauty of the depths, the beauty of the depths, and the thoughts of taking care of the trivial things in life, Lu Qiujian understood at this moment why Professor Xuft said his temper was a little strange; , You do n’t have to do it!

The materials of the otaku are either hidden in the mobile phone. Either hide it in a folder on your computer that is named the joystick driver or Mao Xuan, or change the cover of the teaching aids under the pillow. There is no such thing as Professor Dittrich, so magnificent, directly magnified into dozens of square meters and pasted on the wall of his office!

Amount, but then again, it is not easy for otakus to find such high-resolution pixel photos! I am afraid that no teacher of Deyi Shuangxin has ever made such awesome works, right?

"Look at this super galaxy cluster!" Professor Dietrich tried to reach out to pull Lu Qiujian past, but he was consciously avoided by him, who knows what he has in his hands! Ok. Fortunately, I saw that the lady secretary at the door seemed to have good personal hygiene habits, otherwise it would be bad if you accidentally killed.

"Are you saying this?" Lu Qiujian followed him two steps, looking at the star cluster shrouded in red and blue by the index finger of his right hand.

"Yes, that's it." Supercluster clusters are higher-level celestial systems formed by the clustering of several clusters of galaxies, and they may span billions of light-years of space. More than 5% of the visible universe, the typical velocity of the galaxy is about 1000 km / s. "This super galaxy cluster is named Abel 222/223."

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

"Well, after our calculations, normal matter is part of the filament of this super galaxy cluster ~ www.readwn.com ~ but only accounts for 10% of its mass, and the rest is probably dark matter!" Di Professor Trich enthusiastically introduced the results of his team to Lu Qiujian, "We can see that the two galaxy clusters collided. During the collision, the plasma interaction was so strong, but the two clusters of dark matter However, there is no obvious interaction and it has passed through the other side intact to the other side. This is a very important observation evidence that dark matter exists in the galaxy cluster and is separated from baryon matter under violent impact. "

"A very remarkable discovery!" Lu Qiujian exclaimed that colliding without dissipation is one of the characteristics of dark matter; if two snowballs collide like these two star clusters, they may stick together into a new Big snowball.

But dark matter is different. According to the traditional view, there is no interaction other than gravity between dark matter. When they meet, they will not stick together like two snowballs, but will "penetrate" each other, and kinetic energy will not. Dissipation occurs. Because it does not dissipate, there is no possibility that the dark matter in the universe will continue to collapse until a relatively dense "dark matter star" is formed.

This cosmological model also explains this photo taken by Dietrich well, proving that dark matter is a quite successful theory. (To be continued.)
