Chapter 82 Courage

"Walk!"

   Lu Yu gave an order, and the space jump started again.

  Even the speed of light and constant changes cannot penetrate the armor of the Silver Star. This may be a cage of a certain civilization, but it is definitely not the Silver Star!

  It reached 1 light-year away from the black area in the blink of an eye. The black area cannot affect the space jump, so Lu Yu was slightly relieved.

  Looking from one light-year to the black area, there is pitch black, without any light and gravity detected, as if it was nothingness.

   "So the entire star system that fell into the black field has become a relatively independent system of the universe. 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 and survive, the increase in entropy can quickly collapse the entire civilization, right?"

  The increase in entropy has a huge and irreversible 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 the current state.

  Entropy is a value that measures the degree of chaos in the distribution of matter in a system, and it was born from the second law of thermodynamics. The concept of entropy can be illustrated 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, even a computer, a human being has its own entropy value.

  The entropy value can be divided into different sizes. A newly built house has a very low entropy value because it is very neat and orderly. A dilapidated, dusty house that has not been cleaned for a long time has a higher entropy value than a new house.

  A broken mug has higher entropy than a good mug, an old computer has higher entropy than a new computer, and a rotting corpse has higher entropy than a living person. In short, the more dilapidated and chaotic the structure of a thing, the higher its entropy value.

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

  If a house is regarded as an independent system. Over time without the influence of external energy, external organisms, etc., all external conditions. This house is only likely to get more and more chaotic. The white ash on its walls will fall off, and the house will collapse. In the end, all the substances that make up this house will be evenly distributed in this system. At this time, its entropy value will reach the highest.

   Replace the house with the universe, and the end result of entropy increase is heat death. At that time, there will be no celestial bodies in the entire universe, and 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 amounts of leptons and photons.

  The atomic structure will be completely destroyed, all matter will cease to exist, and only death will live forever.

   This is the inevitable ending of an independent system, and it is also one of the famous conjectures of the end of the universe.

   As for the currently observed situation outside the black domain, it has almost become a small independent system that does not communicate 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’s really hopeless, goodbye!

  Go back and get the star map!

  The simple investigation was completed in this way, and it seemed that this would be able to complete the Qing Clan's commission.

   Lu Yu thought about it and decided to do his duty more.

   This time we jumped ten light-years away, and the observed position of the black field was ten years ago.

   Comparing the two, there is a subtle difference.

   "This black area is shrinking little by little."

  No. 7 compared and analyzed the observed results, and quickly came to a conclusion: "The black field a year ago was narrowed by nearly one light second in diameter compared to the black field ten years ago."

   This is much more interesting.

  Since we want to block this civilization, why do we continue to shrink the black area?

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

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

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

   Then it jumped to four hundred light-years away. Compared with this, the scope of the black area has shrunk significantly.

   It has shrunk from the position of the outer nebula to the position of the astrolabe.

  If it is converted into the solar system, it means that the scope of the black domain has shrunk from the location of the Otter Nebula to the Kuiper Belt.

  This peculiar situation aroused Lu Yu's curiosity instead, and a dozen space jumps allowed him to quickly obtain the observation data he wanted.

   This star system fell into the black region about a thousand years ago, and the black region has been shrinking since 800 years ago, but after nearly 300 years ago, the shrinking range has become negligible.

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

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

  When he came to such a conclusion, there was another mystery in Lu Yu's mind.

   It can’t be a high-level civilization experimenting with weapons, just randomly pick a lucky civilization, right?

  Since a civilization has fallen into the black region, why continue to reduce the black region?

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

   "Are we going back?"

  The No. 7 reminder brought Lu Yu's thoughts back to the present, and the current observation results are enough to deal with the Qing Clan.

   But Lu Yu hesitated instead.

  Because in his opinion, there is definitely some secret hidden in the black domain!

  After encountering the wormhole crisis, Lu Yu began to be cautious again, but the result of personal verification is that the black domain cannot limit the space jump.

  If you even shrink back from this, it is no longer cautious, but outright fear.

  The hymn of humanity is the hymn of courage.

  Let’s not talk about how to face those unknown existences, if you are even afraid of the situation you can control.

   Then I am not exploring the way back to the blue star in the universe, but a coward who is completely frightened and just wants to escape back to the mother star.

  Even if you return to Blue Star in the future, you will be dominated by residual fear!

  And my journey in the universe is really over when I return to Blue Star?

  When I got the Silver Star, maybe my footprints are destined to be in the sea of ​​stars, right?

  Wormhole Crisis Let yourself regain awe and caution, instead of losing your courage and being an ostrich.

  Lu Yu looked at the living area where the blue flowers were blooming again, and then looked at the black area in the starry sky that seemed to have an extra black velvet step.

   What's more, he is not alone, Lu Yu held No. 7's hand and said: "Let's go into the black area again."
