There is no doubt that the Midshrandi civilization declined. When the monster of the universe¡ªa black hole that distorts all rules and even has no rules at all inside¡ªappears silently in its civilization circle, this civilization is destined to inevitably decline. The essence of a black hole is a singularity. This is the supreme mystery of the universe that is wrapped in endless darkness and is unknown to outsiders. The size of the black hole we see is just a phenomenon with the event horizon as the edge after the powerful gravity of the singularity bends space and time. area of ??chaos sphere. Outside the horizon, there are the normal physical rules that we know; when the horizon reaches the singularity, it is in a semi-regular state, where time and space are reversed, there is no size of space, there is only the process of continuous collapse from the edge of the horizon toward the singularity; and when it reaches the singularity, Then time returns to zero, and any physical rules we know from the outside world lose their meaning. The universe we live in has an upper speed limit in its existence. In this universe, nothing can exceed this upper speed limit. In fact, there are many things in the universe that can reach this upper limit speed, such as light, electric fields, and magnetic fields. , gravitational field. The first three can be said to be different manifestations of the same property. The gravitational field is a special existence that transcends the limitations of space. They have all reached the ultimate speed allowed by the universe. We often say that the speed of light is the fastest speed. By definition, nothing can exceed the speed of light. It is not because it is the speed of light that it cannot be surpassed, but because the speed of light has reached the ultimate speed of the universe. The correct statement is ¡ª¡ªThe speed of anything cannot 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 may be large or small, and the event horizon of a black hole is exactly the critical point for objects to escape its constraints. At the event horizon, the object's escape velocity is equal to the upper limit of the universe's velocity. Outside the event horizon, because the gravitational field starting from the singularity is constantly weakening, the escape velocity is lower than the upper limit speed of the universe, so the object can break free. Within the horizon, because the speed required for escape exceeds the ultimate speed that the universe can achieve, the world within the horizon is a world beyond the constraints of its rules for the external universe. At least the world within the horizon is no longer Belongs to the control of the external universe. It belongs to the realm of singularity. The distance from the horizon to the singularity becomes a solid wall that blocks the outside universe from exploring the inside. "The black hole is so powerful that its gravitational field completely destroyed the physical rules we know. The main body of the mother civilization was torn into the black hole and became the nourishment of this monster without size, and it moved towards the singularity bit by bit. Falling in the direction" Hearing this, Su Yuan couldn't help but ask: "Falling in the direction of the singularity, doesn't that mean falling in the direction where the timeline is equal to zero?" Many science fiction movies or novels often use black holes to travel through time. The plot is correct from a theoretical point of view. Because for an ideal spherical black hole, its horizon is a complete sphere. If you continue to divide into equal parts toward the singular point, then each tiny equal part is the state of the sphere at different times. The closer you get to the singular point, the equal parts will be reflected in the horizon surface "object" on the time axis. The process of going backwards. That is, from the black hole's event horizon to the singularity. It is the process of "rewinding" everything that the "object" on the horizon surface has ever experienced. To give an example, if a person sets out from the earth to the black hole event horizon, assume that he can perfectly adhere to the surface of the event horizon. Instead of being torn apart by the gravitational difference of the event horizon, then when he crosses the event horizon, he continues to approach the singularity. What actually appears is the process of leaving the horizon and returning to the earth. It¡¯s like a mirror. There are two completely identical worlds inside and outside the mirror. Our theory is that the origin of the universe is the big bang that started from a singularity. So when we cross the black hole horizon, we return to the singularity that is the starting point of the explosion of the universe. Although there seem to be many black holes in the outer universe, and each black hole has a singularity, in fact, every behavior that crosses the black hole event horizon and approaches the singularity is an opportunity for us to move closer to the origin. Because there are no rules for singularities, the "supernatural" existence of black holes itself is the development of gravity to its extreme, breaking the laws of space and time of the external universe, causing it to present an inverted "image". These singularities are essentially our The source of the external universe in which it is located. Jay Enrui nodded thoughtfully: "It is indeed as you said, if the mother civilization can resist the gravitational difference at the edge of the event horizon, they are indeed heading for a channel to go back in time. However, in fact, this behavior only exists in theory , because any object is spatial, and they have size, it means that they cannot withstand infinite equal divisions of the horizon. Therefore, in the process of crossing the edge of the horizon and entering back in time, the space axis and the time axis will be swapped. All objects are torn into infinitesimal pieces¡??Only infinitesimal objects that are perfectly attached to the surface of the horizon can successfully pass through the horizon and enter the process of traveling back in time. " "Infinitely small objects, that is to say, they do not have macroscopic particle properties. Only when they return to a small enough size, that is, in an energy state, can they pass through the horizon? "Su Yuan asked doubtfully." Jay Enrui said: "The research direction of our Midesh Landi civilization is space, and the level we have reached lies in the macroscopic and abstract multi-dimensional space field." There is not much research on this process of time and space exchange. Not only us, but also the time-based Offi civilization, which is almost the same as our Midshrandi civilization, does not have much understanding of this conversion process. " "Ophen civilization? " Su Yuan was puzzled by this unfamiliar term that suddenly appeared. And the point is that this Offi civilization is actually almost the same as the Midshlandi civilization, and it takes time as its main direction. " Jay Enrui smiled like a spring breeze, As if he suddenly broke free from the historical situation of the destruction of his mother civilization, he said: "The Offi civilization is a distant civilization located beyond countless river systems. When our Mideshlandi civilization reached its extreme development, an accidental opportunity I know that this civilization is no less powerful than ours! " "The main direction of Orpheus civilization is time, and they are omnipotent in the field of time. Through technological exchanges, there is no distinction between our two civilizations in terms of conventional technology. However, the main directions of the two civilizations are different. One specializes in space and the other specializes in time. " "In the Orpheus civilization, their genius scientists proposed the time-energy equation, and the energy generated by the time-energy engine is not weaker than our air-energy engine in any order of magnitude! By converting time in a certain area into energy, a space can be aged in advance, thereby extracting huge energy. It can also be used to inject huge energy into a certain space range to delay the aging of this area" Because we have achieved this The technology of the Orpheus civilization has made the achievements of the Orpheus civilization far beyond other civilizations in life sciences. The average life span of an ordinary Orpheus civilization member has reached a terrifying 20,000 years. And some scientists and politicians who are under special protection are out of civilization. The need can be extended to one hundred thousand years. In front of the Offi civilization, the Midesh Landi civilization is like a young and energetic young man. In many cases, the Offi civilization takes care of this "elder". "Rebirth" and a civilization that has achieved remarkable achievements. "Didn't your two civilizations go through technological exchanges in time and space?" "Su Yuan asked strangely. "Technical exchange? "Jie Enrui smiled, "Of course this exists, but what is being communicated are all irrelevant and non-core ideas. You have to know that no civilization can completely open its main research to another civilization. comminicate. Although the ancient and powerful Offi civilization is friendly to us, how can we easily reveal our trump cards? ¡± In fact, the Offi civilization, which is good at time, and the Midesh Landi civilization, which is good at space, are both very proud. They both believe that only time and space are the most powerful research fields. When they achieve great results in one of these fields, When they use this to push civilization to the extreme, their worship of their own subject research reaches its peak. In this way, they have psychological resistance and contempt for another completely "unfamiliar" field rather than taking the risk to study it. In a technical field that is relatively unfamiliar and requires huge financial resources, material resources and manpower, it is better to concentrate all your energy and continue to advance in the fields you are good at. You must know that scientists are precious assets and must not be dragged into a "slow-down main research" by the so-called temptation. "Go down the wrong path! This is not to be self-conscious, but to meet the unpredictable universe, we must always keep moving forward in our own areas of expertise and maintain the advancement of civilization. Hastily dividing our forces and engaging in other research may lead to the progress of the main research "Of course, our technological exchanges have also made substantial progress. The Orpheus civilization has obtained technologies such as space folding, super-curvature navigation at thousands of times the speed of light, and space shields from us, and we have also obtained it from the Orpheus civilization. Time defense cover, stationary field cannon, wide-area annihilation field and other technologies, and jointly developed the technology of ultra-long-distance time and space jumping By establishing a star road transfer station, we can further solve the problem of ultra-long-distance navigation. . " At this point, Jayne Rui sighed: "At the most critical moment, it was also the Offi civilization that saved our Midshlandi civilization! " "Due to the sudden appearance of the mysterious black hole in the civilization circle of the mother civilization, the entire civilization circle is shrouded in the strong gravitational field of the black hole. According to the principle of relativity, time passes slowly in areas with strong gravity. Although from the appearance of the black hole to the mother civilization, It only took a few minutes for the collapse to occur, but to the outside world, hundreds or thousands of years have passed.time. " "The Offi civilization, which has close communication with the mother civilization, suddenly discovered that the messages from the mother civilization were interrupted, so it sent a fleet to check. It was precisely because of the arrival of this fleet that it was possible to use the static field cannon and the wide area annihilation field. method to save some members of the mother civilization. This is the predecessor of our exile branch. " "After the exile branch survived, it witnessed the process of the entire main body of the parent civilization being swallowed by the black hole. After that, the space collapsed, and the mysterious black hole also disappeared after the collapse of the space for some reason. "(To be continued)
