Rebirth of Northern Technology - Chapter 629

May 1994

Sun company released the Java language. Weekend weekend.

After Cheng Yongxing returned to Spring City from Bingcheng, he went to Lin University to report.

Lin University has been in school for a long time, but he has not come to class this semester.

After nearly two years of intermittent study, he basically matched the professional level of mathematics and physics undergraduates, but it is meaningless to continue to study and study.

Studying in boring theoretical fields is not his strong point. He has neither patience nor time.

Many things have come to an end.

With the help of Professor Zhang, he convened a new research team. The main members of the group are master’s students and junior doctoral students.

This research team is not the same as before. The previous groups had considerable autonomy, finding their own topics and writing their own essays.

The new team will perform calculations and research in accordance with his ideas.

Xie Hang led a group of young people to gather in the conference room of the Physics Building.

The physical building was only opened soon, and the facilities are brand new.

In Spring City in May, the weather has turned warmer, but as the heating supply ceased, the room was not as warm as before.

Through the spacious plastic-steel windows, the incoming sunlight brings warmth to people.

Traditional wooden windows and iron windows generally suffer from poor sealing and easy deformation. In addition, the load-bearing capacity of wooden window frames is limited, and the glass cannot be made too large, which greatly affects the indoor lighting.

Therefore, the appearance of plastic-steel windows has been well received.

Of course, the disadvantage of plastic-steel windows is not that they are expensive.

Plastic-steel windows have just been introduced into the country, and the physical building might be the first in Spring City. Fortunately, the basic fund is not short of money, and the hardware facilities of the physical building, in principle, only choose the expensive ones, not the right ones.

The money was not spent in vain. Simply a single row of large-area glass windows raises the class of the meeting room.

Xie Hang is a doctoral student under Professor Zhang, and he is one of the few graduate students of the university who read Ph.D.

Most of the doctoral students recruited this year are from outside schools.

Many people apply for master’s or doctoral candidates of Lin University just for employment. Graduate students and doctoral students in the Department of Physics of Lin University have become a fast lane to enter the semiconductor industry.

Due to the special relationship with Lin Fanping, Lin University graduates are very popular in Lin Fanping. This is very attractive to students majoring in physics.

For pure science majors, Lin University is the best choice besides going abroad.

Xie Hang has no employment pressure because of his girlfriend Wei Xihan. The combination of the other two people should always relax one by one. The girlfriend’s work pressure is very high, and he has to make sacrifices, such as freeing up more time to take care of the family.

He commanded the group of juniors and younger sisters to clean up the meeting room completely.

The conference room is used for the first time. Although the tables and chairs are new, there is a layer of dust on the surface, which should have fallen during construction.

When Cheng Yongxing came in, the meeting room was already bright and gleaming.

Without too much nonsense, he directly threw out his theory.

————————

The mainstream theory of universe formation mainly refers to the Big Bang theory.

There are always some problems with the big bang theory.

For example, how big is the universe? Where is the boundary of the universe, the expansion speed of the universe and many other issues. These theories lead to a very far-fetched interpretation of the Big Bang theory.

The first question, the expansion rate

The Big Bang theory believes that the universe expanded from a base point.

Especially in the first very short time, the universe expanded to a very huge range.

Its expansion speed far exceeds the speed of light, which obviously violates the basic common sense that the speed of light is the highest speed.

The second question is why does the universe keep expanding? And the expansion speed is fast and slow.

The third problem is Fermi’s paradox.

According to observations and the Big Bang theory, it is estimated that the universe is now 13.8 billion years old. Why is there no sign of a civilization in the entire universe until now?

Where have all these civilizations gone?

Are all intelligent creatures encountering the same obstacles and failing to reach the point of roaming the universe?

The fourth, dark energy, dark matter theory.

Dark energy appears because traditional calculations cannot satisfy the observed results, and a new variable is artificially added to balance the equation.

In other words, the observation results did not meet the calculation expectations, so the physicists cheated.

There are many similar situations.

There are many shortcomings in the Big Bang theory. In order to compensate for these shortcomings, various strange hypotheses have been produced. Many hypotheses are not in line with common sense.

But because the Big Bang theory has been publicized for a long time, the three of them become tigers, which is not the truth, but also the truth.

All physics textbooks, even high school textbooks, are based on the Big Bang theory.

Although some people also raised doubts about the Big Bang theory, there has never been a big climate. The fundamental reason is that large-scale cosmological theories are difficult to verify.

Prove that any small theoretical link requires a lot of energy to do experiments, and this energy is even in units of stars.

The Big Bang is similar to string theory. Both are utopian theories, which are difficult to prove and difficult to overthrow.

————————

To overthrow the Big Bang theory, in this era, although there are no Planck satellites, Cheng Yongxing also has an advantage that no other physicist has, that is, he has money.

The basic fund sits on more than tens of billions of funds. In addition, with a series of entities such as Lin Fanfa, Duhua, Lin LCD, etc., they will gradually enter the listing cycle. The funds after the cash of these companies are the sharpest weapon in his hand. .

The research team organized this time is one of the results.

In addition to being rich, he has power.

The power here does not refer to power, but his creditworthiness.

In the past few years, the slightly more important discoveries of the scientific community have the shadow of Cheng Yongxing behind them.

Just as investors are paying attention to his every move, countless forces are also paying attention to his movements.

Since the beginning of blue LED, Cheng Yongxing has made a step by step, as long as he has participated in scientific research projects, industrial projects, or theoretical research, no one has failed.

No matter what theory he came up with, even if it was nonsense, someone would be more truthful.

This is due to the prestige.

“Today we gather together to conduct systematic research on the theory of “Black Hole Universe”.”

The black hole universe hypothesis was put forward very early, but it has always been circulated among enthusiasts and has not been recognized by the mainstream scientific community. Even thirty years later, relevant information can only be seen in popular science forums, and discussions are rarely seen in serious journals.

The observation result of the Planck satellite is undoubtedly a major earthquake for astrophysics.

After the Big Bang theory was overthrown, the only self-consistent theory that still has some hope is the black hole cosmology.

Cheng Yongxing took out the black hole cosmology in advance. In a sense, in the area of ​​astrophysics, 1995 is already at the same starting line as the following 2019.

Even in this time and space, it’s a little bit ahead.

In later generations, physicists who grew up under the education of the big bang theory still did not give up. They wanted to continue the life of the big bang theory through continuous patching.

The bigwigs who hold the right to speak in the science and technology world will not give up, or say, immortality, the black hole universe theory, there is no day at all.

“The first point is that the black hole universe must meet the most basic black hole conditions.

According to the calculation of the total mass in the universe, we can calculate that the Schwarzschild radius of the black hole in this universe is 150 billion light-years, which has far exceeded the actual radius of the observable universe, 46 billion light-years. Therefore, the black hole cosmology has the most basic foothold. “

The Schwarzschild radius refers to the escape radius of the black hole. All rays smaller than this radius cannot escape the gravitational range of the black hole.

The theory of black hole universe hypothesis has many branches in history.

Some physicists believe that black holes and white holes are twins. After a black hole swallows an object, it will be released in the form of a white hole. Our universe is in such a white hole.

Other physicists believe that when the density of matter in a black hole is approximately equal, an equilibrium state can be reached, which gives rise to our universe.

Others believe that the three-dimensional universe we live in is just a holographic projection of the surface of a four-dimensional black hole.

But these kinds of hypotheses all have their own problems.

The black hole and white hole theory is not actually a black hole cosmology theory, it is just an explanation of the Big Bang theory.

The theory of equilibrium black holes cannot explain why stars do not move closer to the center of the universe, which is why they have not received the attention of mainstream academic circles.

These ideas can only partially explain some phenomena, but there are contradictory loopholes in the overall logic.

“Second, the concept of singularity.

What does the singularity mean for those of us from the black hole? “

There was finally some commotion in the conference room.

The content that Cheng Yongxing said above is considered pediatrics to the top students in the physics department. The black hole cosmology is not unfamiliar to them.

But the singularity is different.

General relativity ends at the singularity.

Within the singularity, all the laws of physics are invalid.

In his later years, Einstein even denied the existence of black holes.

————————

“According to the traditional understanding, a black hole is a stellar body that is constantly attracted by its own gravity and is formed by constantly collapsing.

When the collapse continues and eventually becomes smaller than the Schwarzschild radius, will the collapse continue?

If it continues to collapse, isn’t it a situation where a black hole is surrounded by a black hole?

If it does not continue to collapse, what force stopped the collapse? “

No one can answer Cheng Yongxing’s question.

Because no one can explain the world within the singularity.

“We assume the following scenario, a luminous object that emits light within the Schwarzschild radius. According to the principle of black holes, the light it emits will eventually point to the center of the black hole. Because all light cannot escape the black hole’s gravity.

But at the same time, according to the principle of light path reversibility, if we replace the luminous object with the observer, all the light he sees is actually emitted from the center of the black hole. “

Cheng Yongxing paused, giving everyone time to think fully.

“In the eyes of the observer inside the black hole, he will find that no matter which direction he looks in, up, down, left, right, front, and back are the center of the black hole!

For the creatures in the black hole, the black hole surrounds the space inside the black hole! “

Cheng Yongxing spent a big circle on the white board, indicating that the black hole is the outer boundary, not the center of the circle.

“In other words, in the spatial structure of the black hole, it is the gravitational force of the black hole that supports the internal space. In the interior of the black hole, the gravitational force of the black hole no longer attracts objects together, but separates them. “
