As early as the last century, mankind discovered the vacuum zero point energy.

Nobel Laureate Academician Li Zhengdao put forward the concept of vacuum engineering for the first time in "Introduction to Particle Physics and Field Theory".

Using experimental methods to change the nature of vacuum is called vacuum engineering.

If we can really change the vacuum, then we will discover many new and unexpected phenomena.

As the core structure of modern physics, vacuum is the key to a comprehensive understanding of various natural forces.

Therefore, human beings have been exposed to the zero-point energy of vacuum very early.

It's just that the discovery of the zero-point energy of vacuum and the use of the zero-point energy of vacuum are as far apart as the sky.

right now.

The three civilizations in the carbon-based alliance are all urgently studying the vacuum zero-point energy. The reason is still the pressure from the Palese civilization.

Although Yang Yuping's conjecture was based on a combination of science and information, Fang Yuan believed that this conjecture was correct.

In fact, Fang Yuan thought of more.

"Professor, is it possible that the vacuum zero-point energy is dark energy?" Fang Yuan asked ponderingly.

Yang Yuping smiled happily and said: "This point of view has room for discussion. In fact, the term dark energy itself represents the unknown.

"Dark energy and dark matter refer to energy and matter that humans have not yet understood and have not yet discovered.

"The idea of ??dark matter emerged because of the huge gap between mankind's calculation of the mass of the universe and the mass of matter seen in reality.

"Therefore, it is concluded that there are invisible substances in the universe, and these invisible substances are called dark matter.

"Therefore, dark matter is not one kind of substance, it may be two kinds of substances, three kinds of substances, or many kinds of substances.

"Substance, from the surface meaning of this term, is an object that we can see and touch.

"Even invisible air, when we blow up a balloon, we can feel the presence of air.

"Therefore, we will be able to classify the observed substances.

"But, is there anything in the universe that we can't observe?

"Because it is impossible to observe, no one can give an affirmative answer.

"But from an observation point of view.

"There are only a few human senses, the substances that the eyes can see, and that's because this kind of substance can reflect light.

"The matter that the palm can touch is because these matter and our palm can generate friction, and the essence of friction is electromagnetic force.

"With the development of science and technology, we have more and more observation methods.

"For example, scanning tunneling microscopes are called microscopes, but they have nothing to do with optical microscopes. Instead, they use electron motion imaging.

"Until the Large Particle Collider, humans can even discover quarks smaller than protons through particle collisions.

"These observation methods have gone beyond the scope of vision, touch, and hearing.

"Therefore, dark matter and dark energy are things that we cannot observe even if we use technological means.

"Vacuum zero-point energy, to a certain extent, we have discovered, but there is no way to conduct in-depth research.

"As for whether the vacuum zero point energy is dark energy, this is actually a philosophical proposition, not a science."

Fang Yuan nodded and said: "That is, from a noun perspective, as long as the observable matter and energy are no longer dark matter or dark energy. Even this kind of matter or energy used to be dark matter or dark energy."

...

Two months passed in a flash.

The human fleet enters the Yufu dwarf galaxy.

The Yufu dwarf galaxy is a dwarf elliptical companion galaxy in the Milky Way, belonging to a dwarf galaxy.

The Yufu dwarf galaxy is 290,000 light-years away from the Milky Way.

In fact, the Yufu dwarf galaxy is a companion galaxy of the Milky Way, so it is closer to the Milky Way, but farther from the Andromeda Galaxy and the Triangulum Galaxy.

This is also one of the reasons why mankind chose the battlefield of the Yufu dwarf galaxy v232, which is relatively close to the Milky Way.

Mankind took the first battle in the galaxy. It is a better choice to choose a battlefield closer to the galaxy.

If something unexpected happens during this process, there is still the possibility of returning to the galaxy.

After entering the Yufu dwarf galaxy, he began to consider combat issues.

"Does Palese have any reaction?" Fang Yuan began to inquire about intelligence.

"The Palestine home planet has no sign of sending a reinforcement fleet. The reason should be that the Yufu dwarf galaxy v232 is 2 million light-years away from Andromeda. It may be too late to send an additional fleet to support the Yufu dwarf galaxy v232 battlefield." Zhao Anya Replied.

"Are there instructions from the Carbon-based Alliance?" Fang Yuan asked.

The frontal battlefield always belongs to the Carbon-based Alliance and the Palestine civilization.

The human fleet has just entered the Yufu dwarf galaxy, and how to participate in the war requires communication with the Carbon-based Alliance.

In fact, the main thing is to communicate with the mechanical empire.

Because the photosynthetic civilization has less right to speak in terms of military strategy.

Three-eyed civilization cannot be heard, so the main thing is to communicate with the mechanical empire.

"Mechanical Empire means, let us first go to the mechanical empire fortress in the Yufu dwarf galaxy v232. The commander of the mechanical empire theater over there will arrange our actions." Zhao Anya replied.

"Can a remote quantum communication conference be held now? Talk to the commander of the Mechanic Empire theater of Yufu dwarf galaxy v232 first." Fang Yuan thought about it and decided to talk to the person in charge of the Yufu dwarf galaxy v232 battlefield first.

The battlefield of the Yufu dwarf galaxy v232, covering the entire star system, is 1.5 light-years in diameter.

The Mechanical Empire built a space fortress outside the Kuiper Belt as a stronghold for the battlefield of the Yufu dwarf galaxy v232.

This battlefield is mainly in the charge of the mechanical empire. The photosynthetic civilization has participated in the war twice, but failed to capture the Palisades planetary fortress in the Yufu dwarf galaxy v232.

This battlefield has been deadlocked for twenty years, and no results have been achieved.

The main reason for this situation is that the Yufu dwarf galaxy v232 is too far away from both parent stars.

At such a long distance, the cost of sending additional support fleets is too high.

Even if the Yufu dwarf galaxy v232 is captured, the benefits that can be obtained are not large.

Because the Yufu dwarf galaxy is not like the Milky Way, it has a large number of resource stars.

Even if the Carbon-based Alliance captures the Yufu dwarf galaxy v232, it will at most destroy a laboratory of the Palestine civilization.

If the Palestine civilization destroys data quickly, the Carbon-based Alliance will not even be able to obtain experimental data.

Therefore, the battlefield of Yufu dwarf galaxy v232 is not an important battlefield for both parties.

Due to the huge investment and the small gains, neither side has invested a large amount of troops and has remained deadlocked until now.
