Beneath Deep Space

Time began to accelerate like this...

One month...

Two months...

Three months...

The sci-fi "masterpiece" "Under the Starry Sky" on Yufu 2 was still abandoned. After persisting in writing for so long, with more than one million words, when the author published his "eunuch speech", there were still a small number of readers and fans who felt very sorry.

The quality of the genuine readers was relatively high, and they said they could understand; the pirated readers, on the contrary, were cursing, greeting the author, greeting the author's family, etc.... Things in the world are so strange, stealing things every day, and one day they can't steal anymore, but they start cursing, as if they have lost something.

But there is no way, without subscriptions, they can't even survive, people always have to return to reality...Besides, the original work only wrote here, and Chen Luoke and others had nothing to copy, so they could only abandon it...

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

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

…

As time goes by, this decaying planet begins to have interesting stories, but they are only interesting and will not change the root of decay.

Pour a few cups of water into the pond, and it is still just a pool of stagnant water…

A few people succeed, most people fail, the business world is like a battlefield, and the 80/20 rule always plays a dominant role. In this situation where there is no support, the results people gain are often not proportional to the sweat they put in, and they still have to rely on some opportunities and means.

The naked jungle survival law has disappeared in the wealthy new human civilization… But people can still learn again on this planet, they will understand the dark side of various societies, and come into contact with various unspoken rules…

It is precisely because of this that the overall quality of the new humans has changed more.

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

The original society was generally "naive", and the new generation was born in a very harmonious environment since childhood. They thought that this society itself was like this; but now, through social practice, reflection, and summary, they gradually transitioned to universal wisdom, which is an unimaginable step.

One year, two years, three years...

In the blink of an eye, it has been 32 years since the new human civilization came to the Auriga Galaxy. The entire industrial system has long been fully built, including the surface base of Auriga 4, the air collection base of the gas giant planet, the antimatter production base, etc.

The huge second-generation mothership "Home" has a brand new outline.

And the original "Deep Space" will be converted into a large battle fortress.

Even the military ambitiously proposed a super plan to build two other large military spacecraft...

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 among people.

Even Yi Feng himself was startled from his busy work and hurried to this presentation.

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

"By inducing certain reactions inside the stars and adjusting the brightness, large-scale signal transmission can be implemented."

The principle of this "stellar broadcasting" began to play on the screen. As long as thousands of nuclear bombs are scattered around the stars to form a nuclear bomb chain, and after the 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 the information transmitted is not much... It can only tell others that there is civilization here, and it is generally not adopted."

A young-looking man was explaining next to the screen. He was the main person in charge of the gravitational wave research group... Dr. Chen An.

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

"We have successfully developed this method. It can resist the interference of electromagnetic pulses and can be transmitted over a long distance."

Yu Yifeng sat below and touched his chin. The successful research on neutrino communication is of course a good thing for civilization.

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

Theoretically, the speed of neutrino communication is only the speed of light.

Dr. Chen continued on the podium above: "More advanced and more common 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 cannot sense this signal..."

Gravitational wave communication is also the focus of this conference.

A water wave-like pattern is played on the display screen, spreading outward in circles, just like ripples on water...

Gravitation is generated by the curvature of space. 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 the periodic changes of the components of the Riemann curvature tensor, propagating in space and time..."

"You can simply think that it will only change with distance, and the dispersion speed is related to the square of the distance, but it will hardly be hindered by matter... and there will be no interference like electromagnetic waves."

Dr. Chen looks very young, but is actually over three hundred years old.

In this society, it has long been inaccurate to judge a person's age based on appearance.

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

Everyone here laughed heartily. Obviously, everyone is in a good mood. They are not in a hurry to understand the principles, but want to hear 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, are the broadcasts in the Milky Way noisy or silent?

In Yu Yifeng's heart, he is also looking forward to hearing the voice of the Milky Way and communicating with the real interstellar civilization.

Dr. Chen smiled: "The fourth type is supermode broadcast, a variant of gravitational waves. You can think of the universe as a soap bubble and use the vibration of cosmic strings to propagate on a very large scale."

…

The knowledge inside was 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 Observatory No. 1, where there is a gravitational wave laboratory. Many astronomers have received the broadcasts for a long time and collected a lot of information.

As soon as he entered the door, he saw dense data, one after another displayed on the screen, scrolling continuously.

"Are these all data detected by gravitational wave broadcasting?" Yu Yifeng was not polite and asked curiously: "So many?"

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

His eyes were red, obviously due to extreme excitement, his energy was a little exhausted these days.

But it doesn't matter. These older generation scientists have basically transformed into superhuman beings. They are strong and strong, and there is no big difference in their energy if they are overdrawn.

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

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

Humanity's knowledge is already pretty good in terms of depth, but in terms of breadth... it's 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. Human beings currently use dark matter methods.

Dark matter has no electromagnetic interaction and is a particle with a relatively large mass. Its nature is inactive and very quiet. The effect of gravitational waves is more obvious than that of ordinary matter.

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

Humanity has created the simplest nanorobots, but it is only now possible to implement gravitational wave broadcasting, which has to be said to be a bit slow.

But if you think about it carefully, this phenomenon is normal. There are still a lot of details that have not been illuminated in the new human civilization at any level of science and technology branch, not to mention some special and difficult branches.

"Alas, without communication and collision with other civilizations, 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’s my subscription?)
