"Forget it, let me explain."

Li Zhendong turned his head, took the microphone, and explained to the reporter seriously: "What is a cosmic string? A very thin and heavy unified field was born at the moment when the universe was created, and it was a linear defect in phase change!"

Many reporters immediately turned on their recorder and pretended to be very serious.

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

In theory, the distribution of cosmic strings in the universe is a bit like a human neural network, from the Milky Way to the Virgo galaxy cluster, the Rania Kaia supergalaxy cluster, and even the entire observable universe, there are such network structures.

A picture appeared on the screen, which is a 96 billion light-year observable universe.

This picture has not been processed in any artistic way, and any of the light points represent a galaxy. From a certain angle, the distribution of these galaxies is too similar to a neural network.

The reason why the universe forms a network system instead of all matter spreading evenly is because of the cosmic strings.

"Then next, it's how to advance with cosmic strings..."

When the cosmic strings were just born, these strings oscillated at a speed close to the speed of light, emitting huge gravitational radiation. But no matter how huge the energy was, it was still consumed in the form of gravitational radiation for more than one billion years.

But there are also a small number of strings whose energy has not been consumed, which are hidden in the space due to some special reasons. Therefore, there are not many strings that can be used.

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

"…The cosmic strings have very great elasticity. If a string is tied to the earth, it can accelerate the earth to 3000km/h in 1 second!"

Hearing this, a female reporter asked curiously: "Professor Li, your statement seems a bit strange... Isn't the cosmic string not involved in electromagnetic interactions? So how should it be tied to the earth?" : :

"Even if it can be tied to the earth and generate such a great force, will the string of the universe be broken? Strong interactions cannot withstand such power, right? What is it composed of?"

In front of everyone's eyes, Li Zhendong couldn't help feeling a little comfortable, but he pretended to be serious: "I'm just an example to let you understand the nature of it."

"As a one-dimensional thing, it does not participate in electromagnetic interactions, and even if it is around us, it cannot be perceived. Just like neutrinos, it can travel through our bodies without any obstacles."

"So, how to use it to advance? It cannot be the pulling force in it, the answer is..."

"gravitational!"

"But usually, we can't feel its gravity, what should we do? I just said that it is a one-dimensional topological defect that we can take advantage of."

"Professor Li, what is a topological defect?"

"Simply put, it is because of the topological effect. There are always defects in the homogeneous sense. For example, if a certain system has a certain symmetry group, there will be a vacuum corresponding to the symmetry of this failure after the symmetry is broken."

"... There is a transition state with extremely low energy from one vacuum to another. This situation is generally called soliton in academics, which is a topological defect. For a simple example, the magnetic chips of a ferromagnetic system, because both ends correspond to good ferromagnetic phases, but the direction of m is different, and they are two different vacuums..."

Many reporters were making noise and complaining loudly.

With so many professional terms, it is impossible to understand them. Even if you understand them, you cannot write them on the report.

Li Zhendong felt very desperate. He turned around and looked at Zhang Yuan with a smile on his face, and he was a little suspicious about how this guy dealt with the reporters.

"Everyone is calm... Simply put, a condensed state method can be used to reactivate the gravity of the dormant cosmic string."

"How to do it? You can refer to the graviton shielding experiment on the earth. There is something in common... that is, it is necessary to break the gravitational equilibrium state. Of course, it is just a small piece of gravity of a cosmic string, only a few seconds or minutes."

He drew a simple image on the screen: a spacecraft was sailing slowly, and there was a cosmic string ahead. The airship suddenly fired a shell, interfering with the dormant state of the cosmic string ahead, causing it to start a slight vibration and emit huge gravity.

"But this short period of time is enough. Think about it, if a huge gravity suddenly appears in front of the spacecraft while sailing, will the entire spacecraft be sucked over?"

"Of course, this period of gravity will disappear quickly again, but the kinetic energy, that is, speed of the spacecraft, did not disappear."

"Then we activate the strings further ahead and repeat the process constantly. The speed of the spacecraft will become faster and faster!"

This is a...new way of advancing!

All the reporters understood this time.

Gravity Propulsion and Interstellar Sailing

"Letter from the Golden Sun"

"Captan's Human"

In just half a day, after this series of special reports were broadcast, it soon caused a stir in society. Information about the Golden Sun and the promotion of gravity naturally became the most talked about topics.

The human beings who were originally a little lazy have re-exploded to work!

Similar discussions can be heard on the streets and alleys.

"The Captan of the Golden Sun is so far away... almost in two directions. The cosmic string in the middle is still broken, so we shouldn't have run over here on purpose."

"For the first time using cosmic strings to voyage, I should choose a closer star...at least I think so."

"It doesn't make much sense to meet people from the Golden Sun."

Even Kunlun Mountain needs to be slightly modified. After all, gravitational propulsion can be optimized too much compared to traditional working fluid propulsion, and most of the tonnage is no longer necessary to load fuel. Therefore, some fuel warehouses in the entire Kunlun Mountain can be modified into industrial areas, living areas, and agricultural areas.

The mass of fuel used to account for more than 70% of the entire spacecraft, but now it only needs to account for 20% of the mass. Even if it is a little more radical, 10% is actually enough.

This is the superiority of gravitational advancement!

Of course, gravitational propulsion also has certain limitations. Whether it is acceleration or deceleration, it must be carried out near the cosmic strings. In this way, there are fewer stars that can be accessed, and not every star has cosmic strings available near it.

Moreover, the conventional propulsion method cannot be missing. Otherwise, if the entire spacecraft is unable to move without the cosmic strings?

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

Scientists have discovered an available cosmic string located near Glitzer 581, which is absolutely great news!
