Black technology: starting with space jump machine

"Go!"

At Lu Yu's command, the space jump started again.

Even the changes in the speed of light and constants could not penetrate the armor of the Silver Star. This might be the cage of a certain civilization, but it was definitely not the Silver Star!

It arrived 1 light year outside the Black Domain in the blink of an eye. The Black Domain could not affect the space jump, so Lu Yu was slightly relieved.

Looking from one light year to the Black Domain, it was pitch black, and no light or gravity was detected, as if it was nothingness.

"So the entire star system that fell into the Black Domain became a system independent of the universe. Coupled with the sudden change of the cosmological constant, wouldn't the entropy value inside it increase rapidly?"

"Even if the civilization inside has a way to transform its form and survive, the increase in entropy can also cause the entire civilization to collapse quickly, right?"

Entropy increase has an irreversible and huge impact on this universe.

It can be said that it is precisely because of the existence of the principle of entropy increase that time will not flow backwards and the universe has been shaped into its current form.

Entropy is a value that measures the degree of disorder in the distribution of matter within a system. It was born from the second law of thermodynamics. The concept of entropy can be explained with a simple example. Everything in the universe has its own entropy value. A teacup has its own entropy value, a pen has its own entropy value, and even a computer and a human have their own entropy value.

Entropy values ​​can be large or small. A newly built house has a very low entropy value because it is very neat and orderly. A dilapidated house that has not been cleaned for a long time and is full of dust has a higher entropy value than a new house.

The entropy value of a broken cup is higher than that of a good cup, the entropy value of an old computer is higher than that of a new computer, and the entropy value of a rotten corpse is higher than that of a living person. In short, the more tattered a thing is and the more chaotic its structure is, the higher its entropy value is.

In an independent system, entropy can only increase, not decrease.

If a house is regarded as an independent system. Without the influence of external energy, external organisms, and all other external conditions, as time goes by. This house can only become more and more chaotic. The white ash on its wall will fall off, the house will collapse, and eventually, all the materials that make up this house will be evenly distributed in this system, at which point, its entropy value will reach its highest value.

If the house is replaced by the universe, the final result of entropy increase is heat death. At that time, there will be no celestial bodies in the entire universe, all stars, planets, comets, white dwarfs, neutron stars, and even black holes will all disappear, and the universe at that time will be filled with infinite leptons and photons.

The atomic structure will be completely destroyed, and all matter will cease to exist, except for the immortality of death.

This is the inevitable outcome of an independent system and one of the famous doomsday conjectures of the universe.

Based on the current situation observed outside the black domain, it has almost become a small independent system that has no communication with the outside universe. If the blockade cannot be broken, everything inside will eventually evolve into a heat death state of a small universe in advance.

The investigation is over!

It is indeed hopeless, goodbye!

Go back and get the star map!

The simple investigation was completed in this way, and it seems that the commission of the Qing clan can be completed in this way.

Lu Yu thought about it and decided to be more diligent.

This time, the black domain position observed was ten years ago when jumping ten light years away.

There was a subtle difference when comparing the two.

"This black domain is shrinking little by little."

No. 7 compared and analyzed the observed results and soon came to the conclusion: "The diameter of the black domain a year ago was nearly one light second smaller than that of the black domain ten years ago."

This is much more interesting.

Since they want to blockade this civilization, why do they continue to shrink the black domain?

Even if they survive in the black domain, technology will stagnate and they will be trapped in it sooner or later.

Lu Yu thought about it and decided to observe it again.

This time, the Silver Star jumped directly to five hundred light years away, and what they could see was the appearance of this star system five hundred years ago, when this star system was already wrapped in the black domain.

Then it jumped to four hundred light years away. In comparison, the scope of the black domain has obviously shrunk a lot.

It has shrunk from the outer nebula to the position of the star disk.

If converted to the solar system, the scope of the black domain has shrunk from the position of the Oter Nebula to the Kuiper Belt.

This strange situation aroused Lu Yu's curiosity. After more than a dozen space jumps, he quickly obtained the observation data he wanted.

This star system fell into the black domain about a thousand years ago. The black domain began to shrink from eight hundred years ago, but after nearly three hundred years, the shrinking range became negligible.

Lu Yu used this almost cheating space jump to constantly switch the observation position at a position of nearly a thousand light years, and constantly compared the range of the black domain, thus obtaining such an unexpected result.

This is not traveling through time and space, but using the limitation of the speed of light to cross space to continuously observe the history that has happened in the past.

When he came to this conclusion, Lu Yu had another unsolved mystery in his mind.

It can't be that some advanced civilization is testing weapons and randomly selecting a lucky civilization?

Since a civilization has already fallen into the black domain, why do you have to keep shrinking the black domain?

Aren't you afraid that after breaking the blockade, there will be several technological explosions and come directly to seek revenge on you?

"Are we going back?"

No. 7 reminded Lu Yu to return to the present. The current observation results are enough to deal with the Qing Clan.

But Lu Yu hesitated.

Because in his opinion, there must be some secret hidden in the black domain!

Originally, after encountering the wormhole crisis, Lu Yu began to be cautious again, but the result of personal verification was that the black domain could not restrict space jumps.

If even this is retreated, it is no longer cautious, but completely fearful.

The hymn of mankind is the hymn of courage.

Now let’s not talk about how to face those unknown existences. If you are afraid of the situation that you can control.

Then you will not explore the way back to the blue planet in the universe, but a completely scared coward who only wants to escape back to the mother planet.

Even if you return to the blue planet in the future, you will be dominated by the remaining fear!

And does your journey in the universe really end when you return to the blue planet?

When you get the Silver Star, maybe my footprints are destined to be in the sea of ​​stars?

The wormhole crisis made me regain my awe and caution, instead of losing my courage and being an ostrich.

Lu Yu looked at the living area where the blue flowers bloomed again, and then looked at the black area in the starry sky, which seemed to have a piece of black velvet.

Besides, I am not alone. Lu Yu held No. 7's hand and said, "Let's go into the black area again."
