Chapter 103 The Closed Universe

In addition to performance parameters, products are also graded according to who they are selling to.From the most common civilian level, higher vehicle sensors, the higher level is aviation, even aerospace level, and even higher military level.

In the civil and vehicle fields, generally speaking, as long as a strict test report can be provided, it can be entered into the supplier list of many manufacturers.

But in the field of aviation and aerospace, the test report alone is not enough.

Because these markets are not afraid of [-], just in case.

No matter how strict the test report is and how harsh the conditions are, it will not be able to meet the needs of customers.At this time, it is necessary to prove theoretically the reliability of the product.

However, the basic material of MEMS, silicon, has no systematic research on its mechanical properties before.

Entering these markets requires understanding and testing silicon, its doped material combinations, and its basic mechanical properties.

In addition, although some indicators can be calculated and predicted by traditional mechanics.However, when the feature size reaches the micron level, the characteristics of the mechanical system of the micromachine, the physical properties of the material, and its response to environmental changes are very different from the macroscopic world.

Therefore, the commercialization of MEMS has a long way to go.

Of course, having said that, for scientific researchers, now is simply the best time.There are fields of study everywhere.

"Dad, let's go!"

Qu Yanqiu yelled when it was over.

"Young man, very well said."

Qu Feng stood up, patted Cheng Xing on the shoulder, then turned and said to his daughter. "This is another Chen Quan."

Although Qu Feng has been engaged in industrial production for many years and is extremely familiar with quality management and quality control, some things Cheng Xing talked about are still very innovative.
-
"Let's go? Go eat."

Yun Li walked over.There are only two of them left in the laboratory.Since it was the weekend, Feng Yan probably went home early.

"Okay. Let's go."

Cheng Xing calmed down for a while.

He is still satisfied with the performance just now.But Director Qu's last compliment made Cheng Xing feel a little uncomfortable.

He has encountered similar situations many times recently, as long as he does something well, he will receive similar "praise".

With the MEMS project on the right track, Cheng Xing's initial faint worry gradually subsided.But another voice gradually surfaced, that is, the reason why Cheng Xing was selected was because he looked very similar to Chen Quan.

Cheng Xing actually agreed with this statement, because he couldn't find any other reason.

But this statement made Cheng Xing very unhappy.

Generally speaking, if an ordinary person is praised by others, it is mostly as a compliment that he looks very similar to a certain celebrity.But when two stars of the same class, one is considered to be close in style to the other, it is often insulting.

Although Chen Quan has been recognized by everyone in the project team, everyone is a classmate after all. They study the same content and take the same courses. They all have one nose and two eyes, not to mention that Chen Quan is actually better than everyone. To be two years younger.

Cheng Xing, who has just entered university, is now in the mentality of being the third child, and he is very displeased with being treated as someone else's shadow.

Yun Li understands Cheng Xing's unconvinced attitude.

This kind of mentality is not only shared by Cheng Xing, everyone has it more or less.

Students who can be admitted to the University of Technology are either true or quasi-students in middle school.Many people are the top students in the college entrance examination in one district, one county, and one city, and lastly, they are also the top students in a class.

Everyone here is the apex of the teachers and parents. They have been there for ten years and are recognized by everyone as "other people's children".

But there was nothing she could do, and nothing anyone else could do.

Under Chen Quan's halo, everyone became a foil.

"I want to get a Nobel Prize."

When going down the stairs, Cheng Xing suddenly said something without beginning or end.

"How did you remember to say that?"

Yun Li was completely taken aback.Everyone knows what the Nobel Prize is and what its weight is. "Do you mean to study hard and aim for a Nobel Prize in the future?"

"No! I have an idea and want to prove it. This idea will definitely shock the world."

Cheng Xing, who urgently needed to prove his worth, became more and more excited as he talked.

"Oh? What's the idea?"

"Our world, the universe, is actually inside a black hole."

"Black hole? Universe? How do you connect these two things together?"

Yun Li was a little surprised.

"Oh, let me tell you, in the current theory of the formation of the universe, the big bang theory is the mainstream. All the laws of development of things should be from simple to complex, but the big bang theory is extremely complicated from the beginning, so it is only right A far-fetched interpretation of the observations,."

Cheng Xing was naturally interested in science. When he was in elementary school, he designed a gear version of the perpetual motion machine. In high school, he designed the electromagnetic version of the perpetual motion machine.
Cheng Xing couldn't even tell when the idea of ​​the closed space of the universe came into being.

These thoughts, which are very different from ordinary people, have always been hidden in my heart, and I am ashamed to tell others.

until today.

I am who i am!

"Look, in the big bang universe, there are always a few problems that have not been resolved."

"Which ones?"

Yun Li is not very interested in astrophysics, but she still agrees.

Seeing someone agreeing, Cheng Xing's interest in the conversation immediately increased, and he expressed all his thoughts in one go.

A few of these ideas are hearsay, but most of them are Cheng Xing's own conclusions.Because his sources of information are very narrow, mainly the popular science books that a few students can read in the school library in high school.

The big bang theory does have some problems.

The first question, the expansion rate
The Big Bang theory holds that the universe expanded from a point of origin.

In the early days of the universe, it had to expand at a speed far exceeding the speed of light to satisfy a series of observations.This high speed obviously violates the basic common sense and definition that the speed of light is the limit of motion speed.

But the superluminal expansion ended in a very short time, and after a while, the expansion began to accelerate again.

According to the big bang theory, the expansion rate of the universe is repeated and constantly changing, and there is no law at all.

The second question is dark energy and dark matter theory.

The emergence of dark energy is because traditional calculations cannot satisfy the observed results, and a new variable is artificially added to balance the equation.

That is, the observations didn't match the calculation's expectations, so the physicists cheated.

The third question, cosmological principles

According to the principle of cosmology, the physical quantities and physical laws observed by observers everywhere in the universe are exactly the same, and no observer is special.

But the big bang must have boundaries.But the observers on the boundary must see special results.

The fourth question, the black universe

Olbers' paradox: If the universe is stable and infinite, and there are countless luminous stars, then no matter where you look at the sky, you should see a star, and the night sky should be completely bright.

From this perspective, the universe should be white, not black.

The problem of the black universe has troubled astronomers for hundreds of years.

The explanation given by the big bang theory is that the expansion speed of the outer universe exceeds the speed of light, causing the light of those stars to never reach the earth.

But this line of thinking creates a series of paradoxes.

1. Most of the universe is still expanding faster than the speed of light.

2. The universe is bound to perish.

3. The size of the universe is completely unpredictable.

In short, the history of The Big Bang Theory is a history of continuous patching, and each patch will lead to more problems.

The Big Bang Theory, when it is time to be completely re-examined, because the patch is completely unplayable!

"Do you have any ideas for these questions?"

Yun Li was so eloquent that she was poured all the way.

"That's right. In my model, the three-dimensional space in which the universe is located is self-closing, so there is no boundary."

Cheng Xing talked non-stop.

Because his theory is still in its infancy, there are loopholes everywhere, even at Yun Li's level, it can be heard that something is wrong.But instead of trying to interrupt, she kept humming and encouraging.

Until the two reached the door of the second canteen.

"You go ahead."

"What?" Cheng Xing didn't respond.

"You go ahead, we will go in separately."

"Oh."

Cheng Xing understood.

Freshmen who have just entered their first year, if they eat together, they will be gossiped about.
