Chapter 459 Gravitational Wave Broadcast

Time starts to speed up like this...

a month...

Two months...

Three months...

The science fiction "masterpiece" "Under the Stars" on Auriga 2 is still a eunuch. After persisting in writing for so long and writing more than a million words, when the author published the "Eunuch's Remarks", there were still a small number of readers and fans who felt very sorry.

The quality of genuine readers is quite high, which is understandable; on the contrary, pirated readers are cursing, saying hello to the author, greetings to the author's family, etc... Things in the world are so strange. They steal things every day, but one day they can no longer steal anything. He cursed as if he had lost something.

But there is no way, without subscription, you can't even survive. People always have to return to reality... Besides, the original work only ends here, Chen Luoke and the others don't have to copy it, they can only eunuch...

"It's not easy to persist like this!"

Immediately afterwards, a new type of battery appeared on the market. After rigorous testing, the production cost was reduced by 3.5%, but the savings capacity was increased by 5.7%. Such a patent was sold for a sky-high price of... 66 million, causing a small sensation.

…

As time goes by, interesting stories begin to appear on this rotten planet, but they are only interesting and will not change the root cause of decay.

Pour a few cups of clean water into the pond, but it’s still just a pool of stagnant water…

A few people succeed, and most people fail. The shopping mall is like a battlefield, and the 80/20 rule always plays a dominant role. In this situation of no reliance, the results people gain are often not proportional to the sweat they put in, and they have to rely on some opportunities and means.

The naked law of survival in the jungle has disappeared in the wealthy new human civilization... But people can still learn again on this planet. They will understand the dark sides of various societies and come into contact with various hidden rules...

It is precisely in this way that the overall quality of the new humanity has undergone greater changes.

This change is from immaturity to maturity, from ignorance to understanding.

The original society was generally "naive". The new generation was born in a very harmonious environment. They thought that this society itself was like this; but now, through social practice, reflection, and summary, it has gradually transitioned to universal wisdom. This is unimaginable. A big step forward.

One year, two years, three years...

In the blink of an eye, it is the 32nd year since the new human civilization arrived in the Auriga galaxy. The entire industrial system has been fully established, including the surface base of Auriga 4, the aerial collection base of gas giant planets, the antimatter production base, etc.

The massive second-generation mothership "Homeworld" has received a completely new silhouette.

The original "Deep Space" will be transformed into a large battle fortress.

The military even ambitiously proposed a super plan to build two other large military spaceships...

And at this time, a very interesting technology appeared: that is... gravitational wave broadcasting!

This technology based on dark matter theory can accurately measure high-frequency gravitational fluctuations in space, which has aroused great interest.

Even Yifeng himself was disturbed from his busy work and hurried to the lecture.

"According to our research, there are four paths for information broadcast in the universe. The first is stellar pulse signals."

"By triggering certain reactions within the star, the brightness is adjusted to implement large-scale signal propagation."

The principle of this "stellar broadcast" began to play on the screen. As long as thousands of nuclear bombs are scattered around the star to form a nuclear bomb chain, after the simultaneous explosion, the oil film material will be spread and a large amount of light will be emitted to spread information.

"However, this method is too crude and does not spread much information... I can only tell others that there is civilization here, and generally speaking, it should not be used."

A young-looking man is explaining next to the screen. He is the main leader of the gravitational wave research group...Dr. Chen An.

"The second type is neutrino communication, but it can only make directional calls... If you want to use neutrinos to broadcast to the entire universe and in all directions, it requires more power, which is basically impossible."

"We have successfully developed this method, which can resist the interference of electromagnetic pulses and can be transmitted over long distances."

Yu Yifeng sat at the bottom and touched his chin. The successful research on neutrino communication is of course a great thing for civilization.

It means that... all kinds of communications in war will at least not fail due to electromagnetic pulse interference. However, the neutrino receiving equipment is relatively large and can only be installed on large spacecraft.

The speed of neutrino communication is theoretically only the speed of light.

Dr. Chen continued on the podium above: "The more advanced and more common one is of course gravitational wave broadcasting. As long as there is qualified technology, it can send signals to the entire galaxy. Of course, low-level civilizations will definitely not be able to feel this signal... …”

Gravitational wave communication is also the focus of this conference.

A water wave-like pattern was played on the display screen, spreading out in circles, just like ripples of water...

Gravity is caused by the curvature of space, and the curved space oscillates outward over time, resulting in the generation of gravitational waves.

"Gravitational wave communication is more energy-efficient than electromagnetic waves, because the interaction between gravitational waves and matter is extremely weak, and its attenuation is also extremely slow... To be precise, gravitational waves are periodic changes in the components of the Riemann curvature tensor, in Propagation in space and time..."

"You can simply think that it will only spread with the distance, and the dispersion speed is related to the square of the distance, but it will hardly be hindered by matter... nor will there be interference like electromagnetic waves."

This Dr. Chen looks very young, but he is actually more than 300 years old.

In this society, judging people's age by appearance is no longer accurate.

As soon as he finished speaking, a lady raised her hand and asked anxiously: "Dr. Chen, then... what about the fourth type of broadcast? Didn't you say there are four?"

Everyone present laughed knowingly. Obviously, everyone was in a good mood. They were not in a hurry to understand the principles, but wanted to listen to some popular science.

Because the invention of gravitational wave broadcasting means...

New humans can finally receive communications between interstellar civilizations!

This is an epoch-making progress.

I don't know if the broadcast in the Milky Way is noisy or silent?

In Yu Yifeng's heart, he is also very much looking forward to listening to the voice of the Milky Way and wanting to communicate with real interstellar civilizations.

Dr. Chen smiled and said, "The fourth type is super-mode broadcasting, a variant of gravitational waves. You can think of the universe as a soap bubble, and use the vibration of cosmic strings to spread it on a super-large scale."

...

The knowledge inside is not profound. Yu Yifeng listened to the report with great joy. The progress of science and technology is definitely a pleasing thing.

Then, he followed the crowd to the No. 1 Observatory, where there is a gravitational wave laboratory. Many astronomers have been receiving broadcasts for a long time and collected a lot of information.

As soon as he entered the door, he saw dense data, which were displayed on the screen in a long string, scrolling non-stop.

"Are these... data detected by gravitational wave broadcasting?" Yu Yifeng was not polite and asked directly with curiosity: "So many?"

"Yes, the entire Milky Way is more lively than we imagined!" Professor Thomson of the Observatory smiled and said, "We are still continuing the specific translation work, which may take a few days."

His eyes were red, and it was obvious that he was extremely excited and his energy was a little overdrawn these days.

But it doesn't matter. These scientists of the older generation have basically transformed into superhumans. They are strong and healthy, and it doesn't matter if they overdraw their energy.

"The theory of gravitational wave broadcasting is actually similar to that of telescopes, but our measurement technology is far inferior to that of the old L4 civilization, so there are still many errors and we can only detect bands with higher intensity. We are debugging the parameters..."

Hearing the professor's introduction, Yu Yifeng felt more and more that science and technology were as obscure as the sea.

Human knowledge is already good in depth, but in breadth... it is far from enough.

Unexpectedly, gravitational wave broadcasting is only an L2-level technology!

Yes, in theory, L2 can have it!

To measure gravitational waves, dark matter or laser can be used. Humans currently use dark matter methods.

Dark matter has no electromagnetic interaction and is a large mass particle. Their properties are inactive and very quiet. They are more obviously affected by gravitational waves than ordinary matter.

So after the emergence of the dark matter theory, as long as one of the unique particles is controlled with ultra-high precision, and the signal is amplified through a series of technical means, this "receiving broadcast" technology can be realized.

Humans have already created the simplest nanorobots, but they have only just managed to achieve gravitational wave broadcasting, which is a bit slow.

But think about it carefully, this phenomenon is normal. In any level of science and technology branch, the new human civilization still has a lot of details that have not been lit up, not to mention some special high-difficulty branches.

"Alas, without communication and collision with other civilizations, scientific and technological progress will inevitably be slow. The thinking of different civilizations may bring us more inspiration." Yu Yifeng said.

(That's it for today. I'm so tired. Where are you subscribing?)
