Chapter 520 Dark Matter
Lv Yongchang's mumbling was extremely clear in the quiet laboratory.
"Dark matter?!"
The expressions of the researchers standing beside him changed slightly, some excited, some worried...
"Professor, why do you think this is dark matter?"
He Bilin's question came from the side.
...
Different from antimatter.
Antimatter is a substance that humans have actually observed and exists.
And dark matter...
As of today, human civilization has become a fourth-level civilization, but it still exists in theory.
As one of the top astronomers in the Academy of Sciences, He Bilin naturally understands the mysterious thing called dark matter.
First, the definition of dark matter.
It is a kind of invisible substance that may exist in the universe.
At the same time, it is the main component of cosmic matter, but it is not a component of various celestial bodies in the universe.
According to various observations, the proportion of dark matter in the total matter of the universe has reached an astonishing 85%, and at the same time, it occupies 27% of the total mass-energy of the universe!
As for various celestial bodies visible to the naked eye, they only occupy about 5% of the total mass-energy of the universe.
Calculated in this way, all kinds of celestial bodies and dark matter only account for 32% of the total mass-energy of the universe.
So, what about the remaining 68%?
They are the so-called dark energy.
Compared with dark matter, dark energy is more mysterious, and it may even be the driving force behind the accelerated expansion of the universe!
Although humans have not directly found the so-called dark matter, there is a lot of evidence of its existence.
For example, the operation of the Milky Way.
In ordinary star systems, due to the gravitational effect of the main star, the closer the star is to the star, the faster the orbital speed, and the farther the star is from the main star, the slower the orbital speed.
But in the Milky Way or other spiral galaxies, this law is invalid.
In the Milky Way, all stars rotate at almost the same angular velocity.
Simply put, it is the opposite of ordinary star systems. The closer the star is to the center of the Milky Way, the slower the orbital speed; the more peripheral the star, the faster the orbital speed!
This may lead to a result - the outer stars will escape the gravitational control of the central black hole of the Milky Way because of their too fast speed, and then cause the Milky Way to disintegrate!
But this did not happen.
The material distribution in the galaxy can be calculated through the diffusion velocity distribution of visible celestial bodies in the galaxy. After various observations and calculations, the material distribution of most galaxies and star clusters is different from the observed material distribution - visible matter only occupies a very small part of the total mass.
In other words, there is an invisible substance scattered in the universe.
This is dark matter.
In the galaxy, dark matter acts as a "glue" between stars, allowing all stars to rotate around the center of the galaxy at almost the same angular velocity and preventing the disintegration of the galaxy.
...
Lv Yongchang silently watched the picture in the holographic projection.
In the picture, the black matter in the core area of the two-dimensional debris confinement device quietly "stayed" in its position.
He Bilin turned his head and looked at Lv Yongchang with a puzzled look.
Although he didn't know what Professor Lu was thinking at this time, he still suppressed the confusion that kept emerging in his heart.
The reason is simple.
When he was thinking about a problem, he didn't like others to interrupt his thoughts.
Putting himself in his shoes, He Bilin would naturally not interrupt Professor Lu's thoughts at this time.
"I..."
Suddenly, Lu Yongchang's lips moved slightly, and he murmured in a slightly confused tone: "I don't know..."
"But according to our theory, it does fit the definition of dark matter."
"First, dark matter is highly stable."
"It can constrain two-dimensional fragments with such active properties, so its stability is beyond doubt."
"Second, dark matter basically does not participate in electromagnetic interactions."
"In other words, its interaction with photons is very weak, and it basically does not emit light."
"This is also perfect."
"Third..."
"Dark matter participates in gravitational interactions."
"This may explain the strength of the surrounding gravitational shield."
Lv Yongchang's eyes were full of confusion: "If [Painting] simply wants to isolate the interference of particles, this gravitational shield does not need such a high strength."
"According to the latest calculation results, its strength is even more than 10,000 times that of the gravitational shield made by the Latour flagship."
"So..."
"Its main function is likely to constrain the dark matter in it."
He Bilin frowned and nodded thoughtfully: "When you say that... it is indeed a bit similar."
"But, professor, I have a question."
"You say." Lv Yongchang nodded, retracted his gaze from the holographic screen, and turned to look at He Bilin who walked to his side.
Facing the gazes of Lv Yongchang and a group of scientific researchers, He Bilin pondered for a moment and asked.
"What is its energy source?"
"I don't think that the energy produced by the fusion reactor in this small starship can support such a high-strength gravitational shield."
Hearing this question, Lv Yongchang also fell silent.
Yes.
What is its energy source?
As the research deepened, one mystery after another appeared before the Academy of Sciences.
Although the number of reactors in this starship far exceeds that of a normal starship, it is only a fusion reactor of a second-level civilization after all.
Let alone the seventh-level civilization, even for today's humans, the energy produced by any starship equipped with an antimatter engine is not of the same order of magnitude as it!
"Maybe..."
Lv Yongchang stared at the simple but extremely beautiful restraint device in the holographic projection, and said slowly: "The so-called fusion reactor energy supply is just a scam of [painting]."
"It must have its own unique energy system, but we don't know it."
"Professor, what should we do now?" He Bilin looked at the huge restraint device in the holographic projection somewhat unwillingly.
Everyone knew what He Bilin meant by his words.
The restraint device in front of them contained too much technology that far exceeded human civilization.
For scientists, this is like a piece of poison covered with honey.
Like other scientists, Lv Yongchang's face was full of entanglement.
"Huh..."
He exhaled a long breath of turbid air, as if he had let go of the obsession in his heart, and the whole person was relieved.
"Observe and test the gravitational shield."
He glanced at the dark matter in the core area with nostalgia, and said softly: "Whether it is dark matter or a new energy system, it is not something we can touch now."
"Zero, monitor it in real time, and report immediately if anything abnormal occurs!"
The order has been issued, and everyone present had to suppress their desire for truth.
