Under the cover of several F-22 fighter jets, the huge Boeing 747 slowly landed at the Star Ring International Airport in the Galapagos Islands.

Before landing, Pang Xuelin specifically asked the pilot to idly around Star Ring City for several times to observe this city of his own.

Starring City is located in the southeast plain of Isabella Island. In the west is Mount Asul volcano with an altitude of more than 1,600 meters, and in the north is Mount Negra.

Looking down from the plane, the natural lake formed by the crater is like jasper embedded on the top of the volcano, shining with crystal clearness.

Around the volcano, the rugged surface is filled with dark red volcanic eruptions.

But after entering the city, you can see a large area of ​​green around the building complex.

The entire city covers an area of ​​more than 20 square kilometers. Currently, only central business districts, cultural and educational districts, leisure and entertainment districts and residential districts have been planned. In the future, industrial districts, agricultural districts, etc. will be further planned.

Pang Xuelin's goal is to enable Star Ring City to be self-sufficient in most areas before the trough comes.

The Boeing 747 slowly landed at Star Ring International Airport.

When Pang Xuelin got off the plane, he saw the airport laying a red carpet, and hundreds of representatives from all walks of life in Xinghuan City were organized to welcome his arrival.

Under Kant's introduction, Pang Xuelin shook hands with these people one by one.

Among the people welcoming, Pang Xuelin actually saw Ding Yi and the physicist named Baker he met during his speech back then.

After the welcoming ceremony, Pang Xuelin directly boarded a bulletproof car and headed to Star Ring City under the escort of a large number of guards.

The first phase of the Star Ring City project has not been completely completed yet, and you can still see construction buildings on the road from time to time.

Kante arranged an address for Pang Xuelin. It is a large villa area in the cultural and diocese area. According to Kante, the villas are all top scientists who have been dug from various countries to the Star Ring Institute.

Pang Xuelin's home in Xinghuancheng is in Villa No. 1 in this villa area.

In the next few days, Pang Xuelin visited Star Ring City accompanied by Kant during the day and met with the heads of the city hall, police station, court, people's congress and other institutions one by one.

When I got home at night, I began to read more interesting papers from Star Rings Advanced Research Institute in the past few years.

The first thing Pang Xuelin read was naturally the paper from the Institute of Theoretical Physics.

At present, there are more than 500 physicists from the Institute of Theoretical Physics of the Star Ring Institute. In addition to those who have changed careers, any physicists who have made some achievements in the field of theoretical physics around the world have been pulled into the Institute of Theoretical Physics.

In the past five years, these physicists have not been idle, but have opened their brains and constructed some new physics theories through various brainstorms.

There are many old tunes and some very novel ideas.

For example, the paper that Pang Xuelin is reading explaining the "Quickson Universe".

Kuaizi is not a new concept.

According to the special theory of relativity, in order to satisfy the constant change in the speed of light, the transformation between reference systems is the Poincaré transform, and the commonly used Lorentz transformation is essentially a special Poincaré transform.

If the "single-particle state" is regarded as an object of some kind. If these objects are "single-particle states" in different reference systems, then these "single-particle states" must always have some common points.

In mathematics, this is to find the irreducible representation of the Poincaré group and classify it.

People finally discovered two invariants: p^2=guvp^up^v and p^0 symbols, where p is the momentum four vector.

Classify single-particle states based on these two invariants, and six single-particle states will appear, namely, the positive energy state with mass, the negative energy state with mass, the positive energy state with zero mass, the negative energy state with zero mass, the virtual mass state and the vacuum state.

Virtual mass particles are so-called fasteners.

The existence of fast cells is entirely produced by the mathematical structure of the Poincaré transform, but in the end, it is caused by the principle of constant speed of light.

In the light cone in the full momentum space, it is called the time-like space. The time-like space corresponds to mass states. These states are always within the light cone and their speed is always smaller than the speed of light.

The light cone is called light-like space, which corresponds to massless states. These states are always on the light cone and their velocity is always equal to the speed of light.

Outside the light cone is called empty space, corresponding to virtual mass states, which are always outside the light cone and have a velocity greater than the speed of light.

Because of this, in the theory of relativity, the existence of super-light speed is not prohibited, but only "surpassing" the speed of light is prohibited.

The former refers to the state where the speed is greater than the speed of light, while the latter refers to the process of accelerating from sub-light speed to super-light speed.

That is, the so-called: the eternal sub-light speed of sub-light, and the eternal super-light speed of super-light speed.

Real ordinary matter is at the speed of sublight, so it is usually said that the speed of light is the upper limit of the speed of nature.

If substances such as fast-subs are also included, the more common saying is that the speed of light is a barrier or barrier to speed.

That is, ordinary matter: the mass is a real number (the square of mass is a positive number), the speed is lower than the speed of light, and it can never exceed the speed of light upward.

Fast subclass substances: mass is an imaginary number (the square of mass is a negative number), the speed is faster than the speed of light, and it can never be sub-speed of light downward.

However, so far, Kuaizi is just a theoretical hypothetical substance and has no experimental evidence so far.

Even in the Trilogy Trilogy, there is no description of Kuaizi.

Pang Xuelin personally tends to say that Kuaizi does not exist in this universe.

After finishing the paper, Pang Xuelin opened a new paper document on his computer and was about to continue to brush it, when a series of footsteps suddenly came from behind him.

Pang Xuelin turned his head and saw Cheng Xin coming over with a glass of warm milk.

"Professor Pang, it's already eleven and it's almost time for you to rest!"

Pang Xuelin took the milk from Cheng Xin's hand, thanked him, drank most of the time in one sip, and then said, "I will go to bed after reading this paper, you can go and rest first!"

"No, I'll wait until you go to bed before I go to bed!"

Cheng Xin shook his head and sat down on the sofa beside him.

Cheng Xin has almost become Pang Xuelin's housekeeper now. From work schedules to food, clothing, housing and transportation, she will ask about it one by one.

Pang Xuelin smiled, ignored her, and clicked on the paper and continued reading.

This paper is very interesting, discussing dark matter and dark energy.

The author believes that dark matter is just a projection of a four-dimensional object in three-dimensional space, so we cannot observe its existence, but we can feel its gravity.

Dark energy is the projection of five-dimensional space-time in four-dimensional space-time, which gives us the repulsive force of the universe, thus leading to the accelerated expansion of the universe.

Pang Xuelin's eyes narrowed slightly. Although the author did not clearly explain the existence of dark energy and dark matter, there was a hint that dark matter is actually a two-dimensional object after being hit by a dimensional reduction, and the gravity presents in the three-dimensional universe.

This is similar to the explanation of this paper.

Pang Xuelin turned the paper to the homepage and looked at the author's name. He turned out to be an old acquaintance.

Boyle Baker, a student of Edward Witten, met him a few years ago when he delivered that famous speech in the physics community.
Chapter completed!
