Rebirth of science and technology academic master
Chapter 432 Dark Matter Does Dark Energy Exist? (Seventh update)
"Big Brother 6666"
"I am a poor student, but I actually watched it from beginning to end."
"Is there any professional who can analyze whether what the Big Devil said in today's academic report is right or wrong?"
"As a Ph.D. student in physics, I am so confused that I can only clap along?"
"If my teacher could make PPT as good as Academician Qin's, I think I would never score only 30 points in physics!"
"Is this the physical strength of the Big Devil? The two presentations climaxed with warm applause. There are many Nobel Prize winners and Fields Medal winners!"
"Can anyone explain why there is no dark matter or dark energy on that conch? Does the Big Devil think that dark matter and dark energy do not exist in the universe?"
"This is definitely a big mistake. Science has shown that dark matter and dark energy exist."
"."
I don’t know who suddenly noticed that Qin Yuanqing’s conch physical model did not contain dark matter or dark energy, which immediately caused a big stir.
Dark matter and dark energy are a hot topic in physics today. Even junior high school students can talk about dark matter and dark energy.
In 1915, Einstein derived from his theory of relativity that the shape of the universe depends on the mass of the universe. He believes that the universe is limited and closed. If so, the average density of matter in the universe must be 5 × 10 minus 30 grams per cubic centimeter. However, the density of the universe that has been observed so far 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."
Of course, dark matter was not proposed by Einstein. The first people to propose evidence and infer the existence of dark matter were Dutch scientist Jan Oort and Swiss astronomer Fritz Zavic of the California Institute of Technology in the 1930s.
In 1932, Swiss astronomer Fritz Zavic of the California Institute of Technology in the United States first presented evidence and inferred the existence of dark matter. When Fritz Zavich observed the rotation speed of spiral galaxies, he found that the rotation speed of the outer parts of the galaxy was faster than expected by Newton's gravity. Therefore, he speculated that there must be a huge amount of mass that can pull the outer parts of the galaxy to prevent it from being too large. separated from the galaxy due to centrifugal force.
Fritz Zavich discovered that galaxies in large galaxy clusters move at extremely high speeds. Unless the mass of the galaxy cluster is more than 100 times the value calculated based on the number of stars in it, the galaxy cluster cannot bind these galaxies at all. galaxy.
Although people still know nothing about the properties of dark matter, by the 1980s, people had widely accepted the existence of dark matter and believed that dark matter accounts for about 20% of the energy density of the universe.
After the introduction of the theory of cosmic expansion, many cosmologists believe that our universe is a parallel space, and that the total energy density of the universe must be equal to a critical value. This critical value is used to distinguish whether the universe is closed or open. At the same time, cosmologists also favor a simple universe in which the energy density is in the form of matter, including 4% ordinary matter and 96% dark matter and dark energy.
But in fact, ordinary people do not understand that observations have never been consistent with this, and the inconsistency between observations and theoretical models has become more and more acute over time.
In fact, whether dark matter and dark energy really exist has yet to be observed and convincing evidence has not been produced. This dark matter and dark energy is just a hypothesis put forward by cosmologists based on Einstein's theory of relativity to explain the observed phenomena of planets, galaxies, and the universe.
Chinese netizens discovered that the conch physical model proposed by Qin Yuanqing did not include dark matter and dark energy, but they did not know that dark matter and dark energy do not really exist, and the physics community has not formed a unified understanding of this.
However, the huge amount of information contained in this three-hour academic report still caused shock in the international physics community. Different schools of thought in the international physics community commented on Qin Yuanqing's report one after another based on their respective research directions. .
This issue of "Journal of Shuimu University (Natural Science Edition)" and "Journal of Shuimu University (Natural Science Edition) (English Edition)" has received a large amount of downloads and subscriptions in a short period of time. Scholars from all walks of life can't help but want to be the first to do so. learn.
String theory researchers are the happiest, because they believe that from today on, string theory has finally become self-consistent. Qin Yuanqing has made up for the shortcomings of string theory, making string theory no longer as "gold and beautiful" as before. Among them, it cannot withstand all kinds of scrutiny.
For this reason, they worshiped Qin Yuanqing to the extreme and praised Qin Yuanqing as a figure comparable to physics gods such as Newton and Einstein.
Similarly, more physicists have expressed great interest in the conch physical model constructed by Qin Yuanqing. Although this conch physical model has not withstood time consideration and no scholars have yet studied it, there is no question, it provides physicists with a new path, a new perspective, and a broad road leading to the unification of physics.
Of course, not all conch physical models are praised. Scholars from Europe believe that Qin Yuanqing should add the presence of dark matter to the conch physical model, as this is strictly prohibited.
In order to confirm the existence of dark matter, European physicists launched cutting-edge detectors into space and predicted that more than 90% of the matter in the universe is composed of dark matter. Europe has always been at the forefront of dark matter research. Europe basically holds the right to explain dark matter and dark energy, representing authority in this area.
Therefore, European physicists certainly cannot accept the conch physical model proposed by Qin Yuanqing, because if this physical model that does not include dark matter and dark energy is correct, it means that the entire Europe is wrong.
In Europe, the investment in the detection and research of dark matter and dark energy exceeds tens of billions of euros!
First of all, the most unsatisfactory one is the Deutsche Max Planck Institute. They said: "We give positive affirmation to Professor Qin's research results on string theory. We believe that the conch physical model will be used in the unification of physics." However, we found that Professor Qin did not include dark matter and dark energy. We think this is a big loophole and recommend Professor Qin to improve it."
The Max Planck Institute is the most famous non-profit scientific research institution in Germany. Its research funding mainly comes from the German and Italian governments, which is equivalent to the highest academies of science in each country. It is not only a large-scale scientific research and academic organization in Germany, but also the largest, most prestigious and most effective autonomous scientific organization in the world. Its predecessor was the William Royal Society established in 1911. It was named after the famous physicist and Nobel Prize winner German Max Planck in 1948.
The Max Planck Institute has a total of 83 research institutes, 12,000 employees, and 9,000 visiting scientists, postdoctoral fellows and students. Its research involves many research fields such as physics, engineering technology, biomedicine, and basic science. It has always been committed to the international frontier and cutting-edge foundations. Sex research work. After years of history, the Max Planck Institute firmly believes that basic scientific research guides the future direction of mankind, and supports world-leading research results one after another with the concepts of tolerance, freedom, and harmony, making it the world's top research institution. reputation.
Similarly, the Max Planck Institute is also the leading institution of the European Dark Matter Alliance, and their attitude is very clear. After all, as a supporter of dark matter, it is really unacceptable that there are physics experts questioning the existence of dark matter and dark energy.
If they don't object or make suggestions, wouldn't it mean that their previous research on dark matter and dark energy is nonsense? These are all just deceiving people, and they are just nonsense! ?
Not to mention the Max Planck Institute in Europe, even some physicists in China have a strong attitude towards this!
Because of this incident, many physicists on dark matter and dark energy not only expressed their opinions on the TV media, but also bought air tickets to China as soon as possible and went to the site to conduct the theory in person.
Scholars are so pure!
They don't pursue material life very much, but pursue the spiritual level.
For scholars who study dark matter and dark energy, dark matter and dark energy are beliefs. If dark matter and dark energy cease to exist, their beliefs will collapse.
This kind of matter simply involves orthodoxy, and there is no room for compromise!
To be honest, dark matter and dark energy are the same as the previous string theory. Although they are both popular research, their status is also very embarrassing. Firstly, the theory has problems and is full of loopholes. It is just a theory that uses Euler's formula as a The background is based on Einstein's theory of relativity, which may seem bluffing, but it has never been considered a mainstream subject.
Secondly, dark matter is difficult to detect with modern scientific and technological means. Europe has used countless means, including launching the most advanced dark matter and dark energy detectors, hoping to truly detect it from the universe, but has it actually been detected? ? A large number of papers have been produced, but none of them can be 100% convincing, proving that dark matter and dark energy are indeed as predicted by the model. On the contrary, every observation is very different from the prediction of the model. How can this make people convince.
String theory is also difficult to observe with current methods, and what is even more embarrassing is that Europe has the right to speak about dark matter. Europe is the center of world physics. They can describe dead matter as alive and nothing as existing. However, the center of string theory is mainly in the United States, and naturally it has received all kinds of looks.
But now the world has turned upside down, and string theory researchers are proud. Although no one has reviewed Qin Yuanqing's paper, they have instinctively recognized it and thought it was right. Qin Yuanqing gave them great confidence, allowing them to proudly call string theory Theory is the mainstream physics discipline.
Looking at their friends and former classmates who are studying dark matter and dark energy, they are so angry that they want to come to Shuimu University. They feel proud and proud, and they feel so happy!
