Black technology: starting with space jump machine

Lu Yu, who once looked up at the starry sky on an alien planet, thinking that maybe one day he would meet humans in the starry sky, it took almost a day before he received the news that the human deep space fleet had crossed the heliosphere.

This was the first time Blue Star received the news and forwarded it to Lu Yu in Endless Starry Sky. Otherwise, he might have to wait a few more days if he wanted to know the news.

The vast distance in space makes light speed communication seem so slow.

Human beings will find that the deeper they explore into the universe, the more difficult communication becomes.

However, there is no need to develop super-light communication technology to keep communication open for the time being. So far, the farthest planet that humans have visited is the moon, which is about 384,400 kilometers away from the earth. At the speed of light, it takes 1.3 seconds to cover this distance.

Just like when talking to someone on the other side of the world, there will be a slight delay, but it's not a big problem.

But as humans colonize Mars, problems arise. The average distance between Mars and Earth is 225 million kilometers. At the speed of light, it takes 12.5 minutes to complete this distance.

The deeper you explore into space, the greater the difficulties become.

Voyager 1 has already reached the outer space of the solar system, 19.5 billion kilometers away from the earth. We can still receive messages from there, but each message takes 18 hours to arrive.

Alpha Centauri, about 40 trillion kilometers away, is the closest star system to Earth.

It is very difficult to communicate with this star system, and each message takes four years to be delivered. As a result, communication at the speed of light becomes powerless.

Faster-than-light communication will reveal its necessary value as the star field controlled by civilization expands, and a large amount of civilization resources will be invested in research.

According to the civilization technology that Lu Yu is now exposed to, wormhole technology is naturally one of them, but it involves space technology and is too difficult to implement, so it is not within the scope of consideration at this stage.

Tachyons, this mysterious special substance, are a great hope for breakthrough. However, there are too few science and technology-related researches at present, and the progress is slow. I don’t know how many years of preparation it will take to achieve a breakthrough in the application stage.

The most promising thing is the technology of quantum entanglement for communication. The related technological creation is the sophon computer that Lu Yu once captured.

It was also created by a fifth-level stellar civilization, but now humans cannot even figure out the technology tree of a stellar civilization. If you want to reach the peak technological creation of a fifth-level civilization, you also need to embark on a long journey of technological development. road.

But these are all things for later. While mankind is taking another step to defend its home planet, Lu Yu is still waiting in the light bridge for the strange unknown civilization to reply.

"Isn't this unknown civilization using the speed of light to communicate within the civilization?"

"Or does it think that the Silver Star will be doomed if it's in the light bridge?"

Lu Yu was in the lake in his living area. The mirror-like surface of the lake reflected the sun in the sky. The temperature of the sun lamp was as intoxicating as an autumn afternoon. He and No. 7 were floating on the waves on a small boat that looked like a leaf.

Of course, the waves are only generated according to No. 7's will, allowing them to enjoy their leisure time more comfortably in this afternoon.

"In our original plan, this place was turned into a sea, right?"

"The complete underwater machinery can create an effect similar to the rising and falling tide. With the cooperation of the atmospheric circulation system, the sea here will also have waves. Whether you want to surf, raft, or appreciate the wildness of the sea, you can Feel it here.”

No. 7 stroked Lu Yu's head and said with a smile: "At that time, you also said that you would enable some chaotic algorithms for the weather circulation system and the submarine mechanical system. That is to say, at a certain moment, the weather at a certain place above the sea will appear. We cannot accurately predict what kind of scenario it will be.”

"This means that at a certain moment, typhoons, tornadoes, earthquakes, tsunamis and other phenomena may occur here. This is a complete simulation of nature, and the magic and vastness of nature will be most perfectly interpreted here. "

"As a result, the experts at Base Zero were so frightened that they deleted the database and ran away overnight. They were afraid that you really came up with such a system. If, just in case, something happened that would hurt you, they would all be punished by anti-humanity officials afterwards. accusation?"

After all, Lu Yu was born on the planet, and he still retains an instinctive fascination for the natural scenery on the planet. Being able to recreate the wild scenery on the planet in the living area is undoubtedly very attractive.

But the experts at Base Zero didn't think so and were afraid that Lu Yu would be harmed in any way.

Obviously with the help of intelligent robots, the disasters that occurred on these planets can be easily overcome, but in the end, Lu Yu was still not allowed to stuff an ocean into his living area, and could only replace it with an endless blue lake in front of him.

Lu Yu rested on No. 7's legs, closing his eyes and enjoying the gentle caress, and said regretfully: "At that time, Dahai's plan was rejected, so I just wanted to add a mountain to my yard."

"With the help of the atmospheric circulation system, the water vapor from the sea will turn into snow and fall on the mountaintops. The heat of the virtual sun will melt them, turning them into water and flowing down. The water will turn into waterfalls. It becomes a river that irrigates the plants that live on these mountains.”

"Well, having a mountain at home is much cooler than having a swimming pool!"

When planning the living area a long time ago, Lu Yu was still a newcomer in the starry sky who had just passed the survival stage. Although he is still wandering around in the universe, he is no longer alone.

Good times always encounter some strange things.

Lu Yu was still enjoying drifting with the flow, and No. 7 stopped and whispered: "The unknown civilization has responded."

Lu Yu opened one eye and muttered: "Ignore it for now!"

He turned over and hugged No. 7's thigh, changed to a more comfortable posture, and spent this leisure time first.

You have made me wait for almost three months, can't I leave you for a few days?

With such a slightly angry thought, when Lu Yu saw the message from the unknown civilization, it was already a few hours after dinner.

[Powerful unknown civilization, the technology of your spacecraft makes us amazed. ]

[We think you already have the ability to understand the truth of this universe, please move to another galaxy to talk to us. ]

Huh?

The moment Lu Yu finished reading this message, he felt that this unknown civilization probably had a problem with its thinking circuit.

【The story behind +1%】

Hmm... but at the same time, the system prompt made him realize that he was actually one step closer to earning a lot of points.

Forget it, forget it, points are important!

After repairing the Silver Star, where in the universe can't we go?

Thinking of this, Lu Yu turned on the holographic projection and saw that the light bridge in front of the Silver Star had turned into a space gate.

Even if he didn't cross it, the scene far away from countless light years could be detected.

This is a very extreme binary star system, with a white dwarf and a neutron star as the main body of the galaxy. The distance between them has been shortened to less than one million kilometers. At such a distance, the speed of these two extreme stars has reached a terrifying level.

The diameter of this white dwarf is nearly 10,000 kilometers, not much smaller than the earth, while the diameter of this neutron star is only 20 kilometers.

The size difference between the two is so great, but in this gravitational battle, the dominant one is undoubtedly the neutron star.

Due to their own strong gravity, the surfaces of neutron stars and white dwarfs are very smooth, with basically no ups and downs.

However, at such a close distance, the terrible gravity breaks this smooth surface. This white dwarf has become elliptical under the attraction of the huge gravity of the neutron star. The side facing the neutron star is attracted to bulge forward. The same is true for this neutron star. The side facing the white dwarf is also attracted to appear like a small hill.

The strong gravity also caused changes in the internal structure of these two extreme stars. In the constant deformation, compression, and friction of the stellar matter, powerful energy was released, and the brightness of this white dwarf increased further. At this moment, it is not inferior to a real star.

Therefore, Lu Yu was able to observe this extreme celestial system at the other side of the space gate.

This is not a blessed land of civilization, but a forbidden area for life.

Because the brightness of a white dwarf explosion is an extremely dangerous and terrifying thing. It is already the end of the star, but now it flashes the brilliance of a star, which means that a critical reaction is about to occur - a gamma-ray burst!

It is the strongest explosive phenomenon in the known universe. In theory, it is caused by the collapse and explosion of a giant star when its fuel is exhausted or the merger of two nearby dense stars (black holes or neutron stars). Gamma-ray bursts are as short as one thousandth of a second and as long as several hours, and they release huge energy in a short period of time. If compared with the sun, the energy it releases in a few minutes is equivalent to the sum of trillions of years of sunlight, and the energy of a single photon emitted is usually hundreds of thousands of times that of typical sunlight.

But gamma-ray bursts are not just a burst, behind it, there are X-ray afterglow and visible light afterglow. This is caused by the reduction of energy levels. In other words, after the gamma rays are finished, there are still X-rays and visible light emitted. X-ray bursts can last for several weeks, and visible light bursts can generally last for more than a year.

In such an environment, let alone what would happen if there was a planet in the system, even if there was such an unlucky planet one light year away, it would be destroyed by the upcoming gamma-ray burst.

Because the energy level of gamma rays is very high, it carries a huge amount of energy, especially the gamma-ray burst caused by the collision of a neutron star and a white dwarf.

Under the irradiation of the gamma-ray burst, in just a few seconds, if the unlucky planet has an atmosphere, its atmospheric structure will be completely changed, and the atmosphere, which is countless times more active, will carry a large amount of gas into space.

Because it has extremely strong penetrating power, it can not only affect the surface of the planet, but also affect the interior of the planet. Some elements inside the planet will produce some special reactions under the irradiation of extremely high-energy gamma-ray bursts. This gamma-ray burst, which lasted only a few seconds, seemed to have quickly charged the planet in an instant, and it immediately became active with full energy.

The extremely high intensity of volcanic eruptions and large-scale earthquakes completely changed the geomorphic structure of this planet. At its two poles, gorgeous auroras were produced, like silver snakes waving all over the sky, showing their figures in the night sky. Under the illumination of the aurora, the surface of the earth was turned upside down. If it was a blue planet, all the creatures on the blue planet would have died at this moment.

The cause of the death of the creatures was not geological changes such as volcanic earthquakes, but gamma-ray bursts would directly destroy the genes of the creatures. Under the irradiation of this energy level of gamma-ray bursts, the blue planet creatures would not have time to die of cancer, because the protein structure in the body was destroyed in an instant, and then the life activities were forced to suspend.

Therefore, every planet that can stably give birth to life may not be a cosmic miracle, because in the billions of years that it supports the evolution of life, it has not encountered such terrible interstellar disasters.

But these are not the focus of Lu Yu's attention. After all, this super-large interstellar is nothing new to him.

If there is a major interstellar disaster that can interest him, then why not try to put a piece of two-dimensional foil in the central black hole.

See if the gravity of the central black hole that can distort time and space can withstand the attack of dimensionality reduction.

But such an experiment will undoubtedly harm the entire huge galaxy, and countless civilizations and life forms will be extinct because of it. Lu Yu is more or less not to the point of making fun of all living beings.

But then again, this scene is considered a small scene for an unknown civilization, which is very likely to be a level nine civilization.

Why do you plan to invite the Silver Star to this star field?

What topic can't be discussed in the light bridge?

I think it's good here too!

Lu Yu looked at the triangular spacecraft still guarding outside the light bridge, and couldn't help but observe the other side of the space gate carefully again.

And looking at it this way, there is indeed a new discovery.

Because... In this extreme binary star system, according to the feedback from the observation data of No. 7, there is actually a planet.

It is larger than 1.5 times the size of the earth and has its own atmosphere.

Such a rocky planet should have been torn apart and swallowed by the terrible binary star system long ago, and it should not have survived.

But it is indeed in such a binary star system, revolving in a strange orbit.

And this is not the most surprising thing for Lu Yu. After all, with the power of civilization, it is not difficult to save this planet.

Think about it, when the Ring Clan of the eighth-level civilization built a space transfer station at the cosmic node, they used the configuration of massive stars, white dwarfs and neutron stars to achieve a stable gravitational field.

The binary star in front of us is a small scene.

What surprised Lu Yu was that the unknown civilization invited the Silver Star to go to this planet, and according to the data he fed back from the planet, it seems that there is life on it! ?
