Professor Schiffer, Professor Trinon and other members of the defense team sat on the table in front of them, and Dietrich quietly walked to the chair behind them to listen to Lu Qiujian's thesis.

Because this defense was not arranged by the University of Munich, but was made by Lu Qiujian at a special request, he was the only student who made the defense today! Professor Huber, the president of the university, also made a special trip to observe Lu Qiujian's defense today, because he was not a member of the defense team, so he also sat in the audience.

Lu Qiujian walked directly to the defense table and bowed to the tutor and the students who came to listen to the defense, "Dear Professor Schiff and Professor Trinon, thank you for taking the time to participate in my defense. ”

"Lu, have you thought about your plans after graduation? President Huber and I are very much welcome to you becoming the new professor of the University of Munich!" In Professor Schiffer's view, today's defense was just a formality, so he directly asked the question he was most concerned about.

Chancellor Huber in the audience also straightened up, this is also the question he wants to know, as long as Lu Qiujian can be left, at least in the next twenty years, Munich University will not lack a call to arms.

Professor Trinon on the right hand of Professor Schiff looked at Lu Qiujian without blinking, as long as he agreed to stay at the University of Munich, he would not have to be a villain for Bayern.

"I am very grateful to you, Rector Huber, Prof. Trinon and Prof. Dietrich for your teachings, as well as Carl, Dietrich, Ludwig, Frederick and others for their help. Since it was the last moment, Lu Qiujian didn't plan to hide his plan, and Taiwan began to look back on his study and life in the past two years.

At the beginning of his remarks, Rector Huber, Professor Schifft, Professor Trinon, and the rest of the members of the defense meeting frowned, which did not look like they wanted to stay at the University of Munich.

"Beautiful campus. I am deeply fascinated by the erudite teachers, friendly classmates, well-equipped laboratory equipment, and a relaxed and pleasant academic environment, and if I plan to continue my career in the field of theoretical physics, I would be more than happy to accept the invitation of the University of Munich! I think it's more interesting to do something more practical in my research career in the future!" Lu Qiujian paused and bowed to Professor Schiff again, "Not long ago, my motherland invited me to participate in the Xihe Project, and I can't refuse this invitation, so I can only say sorry to you!"

This is really terrible! Professor Trinon is even more depressed than Professor Schiffer and President Huber, and his beloved club Bayern Munich is about to lose its greatest star in the team! Not to mention the fact that he is about to have an academic debate with a Nobel laureate, and he is so depressed.

"Hey!" Professor Schiff let out a long sigh and shook his head slightly. "Lu, I can understand your love for the motherland, but I still think that the theoretical physics community is the best field for you to show your talent!"

When I switched from the mathematics world to the physics world, some people also said this! Naturally, it was inconvenient to reveal his true purpose, and Lu Qiujian was unwilling to deceive this respectable tutor, so he changed the topic, "Thank you very much for your persuasion, but now that the time has come to defend the thesis, should we finish this work first?"

I'll be able to pass you through now!, Professor Schifft almost blurted out. But in the end, it was the stereotypical character of the German that prevailed, and he shook his head a little depressedly. "Okay then, the thesis defense has officially begun, Mr. Lu Qiujian, please explain the content of your thesis first!"

"Okay!" Lu Qiujian opened the printed paper and began to explain his opinion, "The title of my paper is "Inference on the Theory of Dark Matter-Cosmic Expansion", in this article. I will reconstruct a new model of the universe based on existing models of the universe and recent discoveries about dark matter, and make some assumptions about the future of the universe."

This was all information he had received from his previous conversation with 1A7488, who had fallen into a deep sleep, and it was written today without the intention of waking up humanity.

"The universe is expanding, in the process of expansion. Feeling the theory of dark matter and dark energy, space appears out of thin air and is evenly distributed throughout the universe. The Earth, the solar system, and the Milky Way that we observe are also intricately united. This is because gravity dominates in these systems, so we don't feel like we're expanding. However, between galaxies, gravity does not dominate, and we observe them moving away from each other. Unfortunately, according to current calculations, the rate of expansion of the universe is slowly accelerating."

According to this trend, if the density of the universe is less than the "critical density", then the expansion accelerates to a certain limit, and gravity is no longer dominant in any system. First, there are relatively large celestial bodies, such as galaxies, which are loosely gathered together by gravity, then huge stars, black holes, then smaller stars, and finally planets are torn apart, and finally, the space between protons and protons is generated faster than the speed of light, and the atoms disintegrate, but the decomposed lone protons always touch other protons. The universe died forever. Of course, the word "forever" is inaccurate, because space expands at and beyond the speed of light, and time is frozen everywhere in the universe according to general relativity, so this is the universe where the concept of "time" disappears (timeless). It's really, at the end of time."

"The second possibility is that due to the expansion of the universe, the radiation temperature also tends to be absolute 0 degrees, and the universe is plunged into eternal darkness"

"The third possibility is that a giant black hole will trigger the next Big Bang, and the universe will enter a periodic expansion, contraction, explosion"

After an hour, thirteen minutes and seven seconds, Lu Qiujian ended his discourse, "Professors, this is the end of my thesis, thank you!"

Lu Qiujian's theory is bold and meticulously structured, he is based on reality, and he uses extraordinary imagination to paint a new picture of the universe for people, and Professor Schiff and others have been addicted to this beautiful picture for a long time.

"So," Professor Shiff said, turning around, as if trying to say something.

"Then please elaborate on the third possible calculation!" Professor Trinon asked, fearing that he would lose his chance by saying something inappropriate. (To be continued.) )
