There is no doubt that the Mideshlandi civilization has declined.

When the monsters in the universe - a black hole that distorts all rules and even says that there is no internal rule, appears silently in its civilization circle, this civilization is destined to decline in inevitable ways.

The essence of black holes is a singularity, which is unknown to outsiders. The size of the black hole we see is just a chaotic sphere area with the boundary of the vision presented by the powerful gravity of the singularity bends space-time.

Outside the horizon, we are a normal physical rule we know; when the horizon reaches the singularity, we are in a semi-rule state, where time and space are reversed, there is no size of space, and there is only the process of continuous collapse from the edge of the horizon to the singularity; when the singularity, time returns to zero, and any physical rule we know outside loses its meaning.

The universe we live in has an upper limit of speed. In this universe, nothing can exceed this upper limit of speed. In fact, there are many things in the universe that can reach this upper limit of speed, such as light, electric field, magnetic field, and gravitational field. The first three can be said to be different manifestations of the same properties. The gravitational field is a special existence that transcends space limitations, and they all reach the ultimate speed allowed by the universe.

We often say that the speed of light is the fastest speed. It defines that the speed of nothing can surpass the speed of light. It is not because it is the speed of light, so it cannot be surpassed, but because the speed of light has reached the ultimate speed of the universe. The correct statement is that the speed of anything can exceed the upper limit speed of the universe, and this upper limit speed is numerically equal to the speed of light, that is, the speed of electromagnetic wave propagation. It is also equal to the speed of gravitational wave propagation.

Black holes are big and small, and the vocational boundary of a black hole is exactly the critical point for objects to escape and restrain them. In the vocational boundary, the escape speed of an object is equal to the upper limit of the universe. Outside the vocational boundary, since the gravitational field starting from the singularity is constantly weakening, and the escape speed is lower than the upper limit of the universe, the object can break free.

In the horizon, because the speed required for escape exceeds the ultimate speed that the universe can achieve, the world in the horizon is a world that transcends its rules for the external universe. At least the world in the horizon is no longer controlled by the external universe. It belongs to the realm of singularity.

The distance from the perspective to the singularity becomes a solid city wall that blocks the external universe from exploring the internal world.

"The black hole is so powerful that its gravitational field completely destroys the physical rules we know. The main body of the mother civilization was torn into the black hole, becoming the nutrient for this monster of no size, and fell little by little towards the direction of the singularity..."

Hearing this, Su Yuan couldn't help asking: "Falling towards the singularity, isn't that falling constantly in the direction where the timeline is equal to zero?"

The plot of the time traveling through black holes in many science fiction movies or novels is correct from a theoretical perspective. Because an ideal sphere black hole has a complete sphere. If it is constantly equally divided in the direction of the singularity, then every subtle equality is the state of the sphere at different moments. The closer it gets to the singularity, the more it reflects the process of the "object" on the surface of the singularity, on the time axis, which is reflected in the equality, the process of "object" on the surface of the singularity. That is, from the singularity of the black hole to the singularity. It is the process of "reversal" that the "object" on the surface of the singularity has experienced.

For example, if a person sets out from the earth to the black hole horizon, assuming that he can perfectly attach to the surface of the horizon without being torn apart by the gravitational difference of the horizon, then when he crosses the horizon, he keeps approaching the singularity. In fact, what he presents is the process of leaving the horizon and constantly returning to the earth.

It's like a mirror. There are two completely consistent worlds inside and outside the mirror. We theoretically believe that the origin of the universe is a big bang with a singularity as the starting point. Then, after crossing the black hole horizon, we return to the singularity of the beginning point of the explosion of the universe.

Although there seem to be many black holes in the external universe, and each black hole has a singularity, in fact, every behavior that crosses the black hole's horizon is an opportunity for us to move closer to the origin. Because there is no rule for singularity, the "supernatural" existence of black holes itself is the ultimate development of gravity, breaking the space-time laws of the external universe, making it present a reversed "image". These singularities are essentially the source of the external universe where we are.

Jainri nodded thoughtfully: "It is true that as you said, if the mother civilization can resist the gravitational difference at the edge of the horizon, they have indeed walked towards a channel of time reversing. However, in fact, this behavior only exists in theory, because any object is spatial and their size means that they cannot withstand the infinite equality of the horizon. Therefore, when the space axis and the time axis are shifted, all objects will be torn into infinitely small fragments... Only infinitely small objects perfectly attached to the surface of the horizon can smoothly enter the process of time reversing through the horizon."

"An infinitely small object, that is, it does not have macroscopic particle nature. Only when it returns to a small enough state, can it pass through the horizon?"

Su Yuan asked in confusion.

Jainri said: "The research direction of our Midshlandi civilization is space, and the level we reach is in the macroscopic and abstract multidimensional space fields. There is not much research on this process of time and space interchange. Not only us, but also the Orpheic civilization with time as the main body, which is almost the same as our Midshlandi civilization, does not have much understanding in this transformation process."

"Offi civilization?"

Su Yuan was puzzled by this strange noun that suddenly appeared. The point is that this Orpheic civilization is almost the same as the Midshlandi civilization, and it is based on time as the main direction.

Jainri smiled like a spring breeze, as if he had suddenly broken free from the historical situation of the destruction of the mother civilization, and said: "The Orpheic civilization is a distant civilization located outside countless rivers. When our Midshlandi civilization developed to the extreme, we learned by chance that this civilization level is no less than ours!"

"The main direction of the Orpheic civilization is time, and they can do everything in the field of time. Through technological communication, our two civilizations have no distinction between good and bad in conventional technology, but the main direction of the two civilizations is different, one specializes in space and the other specializes in time."

"In the Orphee civilization, their genius scientists proposed the time energy equation, and the energy generated by the energy engine at that time is not weaker than our air energy engine in the order of magnitude! By converting time in a certain area into energy, aging a space in advance, thereby seizing huge energy, and injecting huge energy into a certain space range, delaying the aging of this area..."

Because of the technology in this area, the Orpheic civilization has achieved far more than other civilizations in life sciences. An ordinary member of the Orpheic civilization has an average lifespan of terrible 20,000 years, while some scientists and politicians who are focusing on protection can be extended to 100,000 years due to the needs of civilization.

In front of the Orpheic civilization, the Midshlandi civilization is like a young and energetic young man. In many cases, the Orpheic civilization is taking care of this "rebirth" civilization as an "elder" and has achieved remarkable achievements.

"Have you two civilizations not experienced technical exchanges in time and space?"

Su Yuan asked strangely.

"Technical exchange?" Jainri smiled, "Of course there are some, but those who are exchanged are all irrelevant non-core concepts. You must know that no civilization can completely open its subject research to communicate with another civilization. Although the ancient and powerful Orpheic civilization is friendly to us, how can we easily show the trump card?"

In fact, the Orpheic civilization, which is known for time and the Mideshlandi civilization, which is known for space, are both very proud. They both think that only time and space are the most powerful research areas. When they achieve outstanding achievements in one of the fields and push civilization to the extreme, their worship of their subject research has risen to the peak. In this way, they have psychological resistance and contempt for another field that is completely "unfamiliar".

Instead of taking the risk of studying a relatively unfamiliar technical field that requires huge financial, material and manpower, it is better to concentrate all your energy to continue to advance in the field you are good at. You must know that scientists are precious wealth and must not be dragged into the wrong path of "slowing down subject research" by so-called temptation!

This is not a treasure, but to welcome the unpredictable universe, we must always move forward in the fields of our expertise and maintain the advanced nature of civilization. Split up our troops and conduct other research may hinder the progress of the subject's research.

"Of course, our technical exchanges have also made substantial progress. The Orphee civilization has obtained technologies such as space folding, supercurvature navigation at a speed of thousands of times the speed of light, and space protection shields from us. We have also obtained technology such as time defense shields, stationary field guns, wide-area annihilation field from the Orphee civilization, and have joined hands with the two leaders to jointly develop ultra-long-distance space-time jumping technology... By establishing a star road transit station, the problem of ultra-long-distance navigation will be further solved."

Speaking of this, Jainri sighed: "At the most dangerous moment, it is also the Orpheic civilization that saved our Midshlandi civilization!"

"Because the mysterious black hole suddenly appeared in the civilized circle of the parent civilization, the entire civilization circle was shrouded in the powerful gravitational field of the black hole. According to the principle of relativity, time passes slowly in areas with high gravity. Although it only took a few minutes from the appearance of the black hole to the collapse of the parent civilization, hundreds and thousands of years have passed for the outside world."

"The Orpheic civilization, which has close communication with the mother civilization, suddenly discovered that the message from the mother civilization had been interrupted, so she sent a fleet to check it. It was precisely because of the arrival of this fleet that some of the mother civilization were rescued by combining the static domain cannon and the wide-area annihilation field. This is the predecessor of our exile branch."
