Start a Subspace

After the orbit of a small amount of ice fragments changed, they were attracted by the black hole again. The ice cubes with a mass of hundreds of thousands of tons broke away from the original orbit and fell straight towards the black hole. Immediately afterwards, due to the increasing gravitational force on the ice cube, the falling speed became faster and faster. The difference in gravitational force between the first section and the tail end caused the ice cube to fall apart and become a mass of white mist.

A tiny accretion clump formed.

Even, the moment these water molecules were sucked into the black hole, they squeezed each other, producing a faint light.

People have observed the obvious infinite redshift plane and black hole event horizon.

The infinite redshift surface is a two-dimensional hypersurface in the steady-state space-time, satisfying that the wavelength of the outgoing light-like geodesic starting from this surface to any point is infinite, that is, the redshift factor is infinite.

The event horizon of a black hole refers to the boundary of the region from which even photons cannot escape. .

Due to the relativity effect caused by the space-time distortion around the black hole, the time velocity in this region is zero, that is, when the information with the speed of light reaches this range, the information is in a static state in the eyes of the outside observers. So the layer outside the event horizon of the black hole seems to be full of objects, but in essence it is just the "information" of the object that is about to fall into the black hole...

This part of information will stay on the surface of the event horizon, and slowly return to the original world with the Hawking radiation.

Of course, since the wavelength of the corresponding light is infinitely elongated, it is already far below the range of visible light.

This newly formed accretion cluster is very small and dim. It may be the smallest accretion cluster in the history of this black hole...

The empty cosmic space, the unimaginable darkness, and even a black hole sucking in something is considered a wonder of the world...

But most people are attracted by another scene on the screen.

A jaw-dropping thing happened. After the hydrogen bomb exploded, the ice layer melted, and the meteorite fell apart... a piece of white metal was exposed!

When they saw this piece of metal, everyone's eyes widened in unison, as if they couldn't believe it, and they were still in a daze after a long time.

"Lighting...increase the power of the neon lights."

Under the illumination of the searchlights, these metals shone with dazzling light!

Zhang Ran widened his eyes, swallowed, and turned his head to look at another screen, which was the small universe monitored by three satellites.

He shouted happily: "What is this? Why does it look like... the wreckage of a spaceship? I understand that this small universe is not the small universe of silicon-based life, but the core of an alien spaceship .It’s like building shelters in several small universes in our Dongfang Panshi.”

"An alien civilization died here!"

There is no way out, there is no way out, and there is another village, and there is a lot of metal in the ice layer?

It may even be the wreckage of the spaceship!

Everyone in the captain's room was taken aback, and discussions erupted in surprise.

An astronomer was the first to react, and laughed wildly and proposed a conjecture: "For some reason, the spacecraft of this alien civilization had an unexpected situation near the black hole and disintegrated. In the area where the black hole is located, there are still a few The water vapor. The water vapor slowly condenses on the metal surface to form so much ice."

"If this is true...means this spaceship, may have been here for tens of thousands of years? Can we mine the spaceship's materials, and even recycling can solve the big problem of insufficient resources. Too alright!"

Another professor hastily tapped the keyboard and began to calculate: "Thousands of years may not be enough... Millions of years may not be enough to condense such a large ice cube. The matter here is so thin, Wait, the white hole or black hole is still spewing out a small amount of matter, so it must be counted... Maybe this white hole is spewing out a large amount of water vapor?"

Unable to calculate.

Since the nature of black holes is not understood, humans cannot calculate how long this spaceship has existed.

From hundreds of years to hundreds of millions of years, it is possible.

Could it be that for so many years, other silicon-based life has not found this dilapidated spaceship? Why is it here, circling around the black hole?

Of course, these problems are not big problems, the most important thing is...resources!

The size of this spaceship does not seem small, what's more, there are as many as 13 meteorites here. If there are some metal debris in each meteorite, it may add up to tens of billions of tons!

It can greatly solve the urgent need of insufficient resources...

More importantly, there may be an alien refuge in the small universe... The wreckage of the spaceship is just a small head, and that refuge is the real big head.

Thinking of this, Zhang Ran's heart couldn't help beating wildly. As long as he got this resource, he finally didn't have to pay for it himself!

Thinking of it this way, I felt a great sense of relief in my heart.

He kept telling himself: "Slow down, slow down, don't be too optimistic, maybe there is a terrifying monster sealed in this small universe... Slow down! Don't worry!"

After a long time, everyone's mood slowly returned to calm, but everyone was still talking and laughing.

Zhang Ran said in a deep voice: "Everyone, is there a way to judge the technological level of this spaceship? Is it more advanced than us or behind us? Are there more risks here? How many resources are there?"

"I think it's very difficult." The engineer Lu Qiming who spoke sent some video messages from the subspace, "Look, this is the mouth shape data of the probe. The spacecraft has long been dilapidated. Some of them are more broken...the reason is the change of physical rules, resulting in material denaturation."

"This three-dimensional space has transitioned from the second type of universe to the third type of universe, and the phenomenon of blanching is very serious. Most of the materials have become extremely fragile."

"What's more, it's been too long... well... I don't think that the material of this unknown civilization can resist the erosion of time."

"But it's nothing, as long as it is re-smelted, these resources can still be used."

The detection operation started again, and humans projected several small robots from the space gate.

A rope was tied to the back of the robot, and it ejected several times in a row, and finally, on the third time, it ejected to the position of the metal wreckage.

Under the operation of an engineer, it scraped the metal with a knife, leaving a deep mark, as if facing a rotten piece of wood, it easily completed the corresponding action.

"It's true that the denaturation occurred because of the Lanhua phenomenon, otherwise the spacecraft would not be so fragile." Another expert also shook his head, "In any case, these resources can be recycled."

After the robot cut some metal, the staff in the subspace slowly pulled it back to the subspace with a rope for material inspection and analysis.

About an hour later, the results of the inspection came out: "Report! A total of 16 metal wreckages were collected. The main component is titanium metal, which is a conventional titanium alloy."

"Some suspected chip structures were found, based on chips made of silicon and hafnium elements, but due to too long a time, the circuit structure inside was completely damaged, and there is no possibility of repair."

"What about rare earths, do rare earths exist?"

"Of course it exists! The proportion of rare earth elements is not low, at least 12.6%, and there are quite a few radioactive elements. We suspect that the current wreckage is the energy room or weapon room of the original spacecraft, whether it is nuclear fusion or nuclear fission. It’s hard to identify at the moment.”

The experts in the captain's room looked at me and I looked at you, with joyful expressions on their faces.

Rare earths... finally found.

A series of good news, even Zhang Ran smiled unconsciously.

An expert in the semiconductor industry said: "I think the strength of this technological civilization is quite limited... Even if it is stronger than us, it should not be much stronger. The manufacturing process of these integrated circuits is about 10 nanometers, and transistors are used. The details It’s a little bit different in that they generally use a technology based on hafnium-based oxides, which we basically don’t use.”

"In addition, their computer seems to be a ternary computer. It's a strange structure... Is the technology tree completely different?"

"The technological heritage from Sibadi civilization has almost developed semiconductors to the limit. A more advanced computer should be a photonic computer, or a quantum computer."

Zhang Ran asked suspiciously: "You mean, ternary computer is more advanced than binary? Are we going to change to ternary in the future?"

The expert explained: "No, no, the essence of a computer is calculation. Whether it is a ternary computer or a binary computer, the simple base system will not change anything."

"The former Soviet Union also developed a ternary computer, but the circuit diagram was more complicated and the manufacturing cost was higher, so it was gradually eliminated. We don't have a ternary computer now. Are we weaker than the Soviet Union? ?"

"The most important thing about technology is the cost. After all, the research and development of technology can be said to be endless. Everyone has different standards, and it is understandable that each has its own technology tree."

The development of technology requires the formulation of various standards and various protocols. These products based on the underlying mechanism are quite complicated, and the sunk cost is huge if they are changed rashly.

The manufacturing cost of ternary computers is very high at the beginning, and the ultimate potential is unknown to human beings, and they can only go to the dark in the binary system.

Zhang Ran sighed, and stopped worrying about these things. He directed the staff in the subspace: "First dig out all the metals hidden in the ice layer, as much as you have, and don't deal with the meteorite where the small universe is located. .”

This suggestion has been widely recognized. Even the most radical people know the truth that "ten birds in the bush are worse than one in the hand".

The small universe is unknown, and no one knows what is hidden inside...

Let it be frozen first!
