Chapter 461 Future Development

People combed through these broadcasts, trying to dig deeper.

Soon, a scientist proposed the first hidden information.

The Destroyer civilization, that is, the robbers, does not seem to have a good reputation here.

If the "Destroyer" does not kill the other party in one wave, but lets some of the fish slip through the net, the other party will broadcast the colonies, technology, and weapons of the Destroyer civilization.

Even if you don't have such technology, you can go to a market and ask for help from a more advanced civilization.

"Okay... It's worth noting."

Yu Yifeng saw the wanted posters of the Carret civilization, and various rewards... There is always a strange feeling.

But this kind of broadcast is still quite effective. He did have a certain degree of vigilance. If he encountered a similar spaceship that met the description, he would definitely run away.

He thought to himself: "... New human civilization, generally speaking, is impossible to be a robber..."

Then, people talked about the second point, that is: "Absolute neutrality"!

Dr. Rambo stood up and said first: "Millions of years ago, in the era of Hei, it seemed that 'absolute neutrality' was not emphasized, so... can we assume that the Milky Way has actually undergone some changes?"

"For example, various civilizations are divided into some hostile factions and camps? They hate each other, so some trading markets emphasize the term absolute neutrality to attract other civilizations."

"... Should we pay attention to something? Everyone has heard of words like the Silicon-based Alliance... Is it an alliance created by silicon-based life? Will they fight with... carbonyl organisms? Just like what is written in the novel."

Hearing this, a buzz of discussion sounded in the conference room.

Such a deduction makes sense. Sending gravitational wave broadcasts is much more troublesome than electromagnetic waves. Generally speaking, the sender will not add extra unnecessary information.

Hei opened his mouth and couldn't speak. He didn't know whether his memory was confused or the fact was really like this.

Is the information he has... not enough? He really hasn't heard of the Silicon-based Alliance.

Hei was not the top of the civilization, so he didn't know much about these things. Moreover... since the original civilization fell, the popularization of citizens' cosmic common sense has gradually been despised...

Yu Yifeng nodded slightly and said, "This point is very good. Now let me tell you my opinion."

"The opening of the gravitational wave era means that the entire galaxy can communicate... at least in general. Everyone wants to communicate with alien civilizations in a friendly manner and learn from each other's strengths and weaknesses. This idea is not wrong."

"But our current strength is still relatively weak. Basically, with full firepower, the Home and the Deep Space can be compared to the spacecraft of the Green Light Man at the beginning. Our weapon system is still too weak and can't break the ion shield at all. If we fight with that civilization again, we will still be beaten."

"So, I don't plan to leave the Auriga galaxy directly, but plan to develop for a while and study our nanotechnology..."

"Yes, dig deeper into nanotechnology! Including various nano weapons! We must first have the ability to protect ourselves!"

After hearing his words, everyone present calmed down.

Another more rational scientist also stood up to support: "Yes, our science is still advancing by leaps and bounds, and it requires a lot of resources to promote it."

"It is indeed irrational to leave this star at present..."

"No matter what factions there are in the galaxy, or whether there are hostile parties, it has no effect on us at all, and it is not important! As long as we develop ourselves well!"

Yu Yifeng nodded and continued: "While focusing on development, we must learn more information through interstellar broadcasts during this period of time."

"Only by knowing more things can we have more response plans."

The people in the conference room discussed again.

The first time they came into contact with serious alien information, some people were very excited with adrenaline, but more people were thinking.

With the current strength of human beings, it is easy to bully low-level civilizations, but they are not strong in interstellar civilizations.

You have to endure loneliness and become strong before you can talk.

"We still have to develop. The goal... nanoscience!"

"Dismiss!"

After the meeting, everyone gradually dispersed. Yu Yifeng and others did not leave immediately, but discussed with a small number of scientists.

"Can we send gravitational wave signals?" he asked Dr. Chen curiously.

The gravitational wave information detected so far is very simple, basically just a few sentences. So Yu Yifeng guessed that this transmission technology is more difficult and can only send relatively simple information.

As expected, Dr. Chen shook his head and said: "With the means of the new humans, we can only receive broadcasts for the time being, and we cannot send them. After research, we believe that there are several ways to send broadcasts."

"First, use the vibration of cosmic strings."

Cosmic strings are hypothetical objects in string theory, a bit like spider silk, which can be said to be an extremely high-density energy line with a diameter of only 10^(-29) cm, equivalent to 10 times the radius of a hydrogen nucleus.

However, a one-centimeter-long cosmic string has a greater mass than the entire Himalayas, and the mass is variable, depending entirely on its tension: the longer it is pulled, the tighter it is stretched, the greater the mass.

"When cosmic strings vibrate, knots or sharp corners are formed, gravitational waves can be generated."

Well, this method is certainly not humanly possible. Moreover, the mysterious cosmic strings are usually found at the center of the galaxy, providing strong gravity and pulling the entire galaxy.

This kind of civilization that uses cosmic strings must be much more powerful than humans.

Dr. Chen continued: "The second method is to use neutron interstate matter as thick as a hair to imitate cosmic strings. This high-density material can also vibrate to create gravitational waves."

Yu Yifeng smiled bitterly in his heart. Using the material of a neutron star without letting it explode was even less reliable than cosmic strings.

"So... civilizations that can use gravitational wave broadcasts are much more powerful than us?"

Dr. Chen shook his head: "No, there are still the latter two methods, which we may be able to achieve through technical means. The third one: using the series vibration of artificial black holes!"

In the scholar's explanation, Yu Yifeng understood the basic meaning.

The basic principle of gravitational wave emission is the vibration of long strings with extremely high mass density.

"If you connect a series of miniature black holes and "vibrate" them, you can actually create gravitational waves of a relatively objective scale."

"As long as 10,000 grams of mass are lost, one or two signals can be transmitted, and there is no problem in the Milky Way range. We are currently engaged in research in this area. There are no theoretical difficulties, but technically... we are still unable to create a large-mass black hole. ”

Humans have been able to create ultra-small micro black holes in hadron colliders. However, these black holes will evaporate in a blink of an eye and cannot be retained for a long time.

Yu Yifeng looked at Dr. Chen's indifferent statement and felt a shiver in his heart. Humanity's technology is really becoming more and more dangerous. First it was antimatter, and now it wants to create a black hole.

However, Yu Yifeng has a little understanding of black holes.

For humans, the speed of production in the hadron collider is much greater than the speed of evaporation, and the danger is of course far less than that of antimatter... When the mass of a black hole is not large, its gravity is extremely low and cannot absorb even a proton. Go in, let alone destroy the whole world.

"It doesn't matter. If we can find a way to create a large black hole, or find a natural black hole with only a billion-ton level, we may be able to gain more."

Dr. Chen continued: "There is also a fourth, simplest way, which is to use some dark matter to distort space... through dark energy, dark matter, imitating gravitational waves, to transmit space ripples to the outside world."

"This principle is very similar to the curvature engine, except that it changes from building a curvature bubble to diverging outward."

"I think this method is the simplest, even an L2 civilization can achieve it!"
