Deep Space Planet Leader

"Forget it, let me explain."

Li Zhendong turned his head, took the microphone, and explained to the reporter solemnly:" What is a cosmic string? A very thin and heavy uniform field, born at the moment of splitting heaven and earth apart in the universe, is a linear defect in the phase transition!"

Many reporters immediately opened their recordings Pen, pretending to be very serious.

"It is divided into two types, one is a straight string that traverses the universe, and the other is a ring string of various sizes. The collection of all the strings forms a network full of the universe."

Theoretically, the distribution of cosmic strings in the universe is a bit like a human neural network, as small as the Milky Way, as large as the Virgo Cluster, the Supercluster of Rania Kea, and even the entire observable universe. Exist.

A picture appeared on the screen, which is an observable universe of 96 billion light-years away.

This picture has not undergone any artistic treatment, and any point of light in it represents a galaxy. From a certain angle, the distribution of these galaxies is too much like a neural network.

The reason why the universe forms a network system, instead of all matter being spread out evenly, is because of the cosmic strings.

"The next step is how to use cosmic strings to advance..."

When cosmic strings were just born, these strings oscillated at a speed close to the speed of light and emitted Huge gravitational radiation. But no matter how great energy is, it is still consumed in the form of gravitational radiation in more than 10 billion years.

But there are also a small part of the strings whose energy has not been consumed, because of some special reasons, they are hidden in the space. So there are not many strings that can really be used.

It is difficult for people to directly observe the existence of these strings. After all, this is a one-dimensional thing, with only length, no width or height.

"...The cosmic string is very flexible. If a string is tied to Earth, it can accelerate Earth to 3000Kmh in 1 second!"

Heard here , A female reporter asked curiously: "Professor Li, your statement seems a bit strange... Isn’t the cosmic string not involved in electromagnetic interaction, then how should it be tied to Earth?"

"Even if it can be tied to Earth to produce such a large force, won't the cosmic string break? Strong interaction can't withstand such a force, right? What is it made of?"

Under everyone's eyes, Li Zhendong became the focus of everyone. Li Zhendong couldn't help but feel a little refreshed, but he still pretended to be serious and said: "I'm just making an analogy to let you understand the nature of it."

"As a one-dimensional thing, it does not participate in electromagnetic interaction, even if it is around us, there is no way to perceive it. Just like a neutrino, it can pass through our body without obstacles."

"So, how do we use it to advance? Impossible is the pulling force, and the answer is..."

"Gravity!"

"But usually, we seem to feel What should I do if I don’t have its gravity? I just said that it is a one-dimensional topological defect, and we can use this topological defect."

"Professor Li, what is a topological defect?"

"Simply speaking, it is the defect caused by the topological effect. In the sense of homotopy, there are always defects. For example, there is a certain symmetry group in a system. The symmetry of the vacuum corresponds to the vacuum."

"... There is a very low-energy transition state from one vacuum to another. This situation is generally called soliton academically, which is a A topological defect. For a simple example, the magnetic chip of the ferromagnetic system, because the two ends correspond to the good ferromagnetic phase, but the direction of m is different, and there are two different vacuums......"

Many reporters were upset and complained loudly.

So many technical terms are impossible to understand, even if they understand, they are impossible to write in the report.

Li Zhendong felt very desperate. He turned around and looked at Zhang Yuan with a smile on his face. He wondered how this guy dealt with the reporters.

"Everyone don't be impatient... Simply put, a condensed matter method can be used to reactivate the gravity of the dormant cosmic string."

"In the end How to do it, everyone can pay respects to the original graviton shielding experiment on Earth. There is a certain common ground...that is, it is necessary to break the balance of gravitation. Of course, it is only the gravitational force of a short piece of cosmic string, only a few seconds or A few minutes."

He drew a simple image on the screen: a spaceship was sailing slowly, and a cosmic string was in front of it. The airship suddenly fired a cannonball to interfere. The dormant state of the cosmic string in front of it caused it to vibrate slightly and exude a huge gravitational force.

"But this short period of time is enough. Think about it. If the spaceship is sailing and a huge gravitational force is suddenly generated in front of it, will the entire spaceship be sucked?"

"Of course, this gravitational force will quickly disappear again, but the kinetic energy of the spaceship, that is, the speed, has not disappeared."

"Then we activate the string further forward and repeat continuously. In this process, the speed of spaceship will become faster and faster!"

This is a...new way of advancing!

Now, all the reporters understood.

"Gravitational Propulsion and Interstellar Navigation"

"Letter from the Golden Sun"

"The Human of Captain"

In just half a day, after this series of special reports were broadcast, it quickly caused a big wave in the society. The information about the Golden Sun and the gravitational push have naturally become the most talked-about topics.

The human beings who were a little slack have renewed their enthusiasm for work!

Similar discussions can be heard on the streets and alleys.

"Captain Star of the Golden Sun, it's so far away...Almost two directions. The cosmic string in the middle is still broken. We It shouldn't be made a special trip."

"The first time I use the cosmic string for a long voyage, I should choose a closer star...at least I think so."

"Go and meet the people of the Golden Sun , It doesn’t make much sense."

Even the Kunlun Mountains have to be changed slightly. After all, gravitational propulsion can be optimized too much compared to traditional working fluid propulsion, and there is no need to change The tonnage of the overwhelming majority is used to load fuel. Therefore, some fuel warehouses in the Kunlun Mountains can be modified into industrial areas, living areas, and agricultural areas.

In the past, the fuel quality had to occupy more than 70% of the entire spaceship, but now it only needs to occupy 20% of the quality. Even, to be more radical, 10% is actually enough.

This is the superiority of gravitational propulsion!

Of course, gravitational propulsion also has certain limitations. Whether it is accelerating or decelerating, it must be carried out near the cosmic string. In this way, the number of stars that can be visited is much less. Near a star, there are cosmic strings that can be used.

Moreover, the conventional way of advancing is still indispensable. Otherwise, without the cosmic strings, wouldn't the entire spaceship be able to move?

On the other hand, devices that cause gravitational fluctuations are also under urgent research.

Scientists have discovered a usable cosmic string near Gliese 581. This is definitely great news!

In other words, everything is ready, only the "Kunlun Mountains" is owed to the east wind.
