There's no doubt that the Midshrandi civilization has declined.

When the monster of the universe, a black hole with distorted rules or even a completely irregular interior, quietly appears in its circle of civilizations, this civilization is doomed to inevitable decay.

The black hole is essentially a singularity, which is the supreme mystery of the universe wrapped in endless darkness that is not known to outsiders, and the size of the black hole we see is just a chaotic sphere region with the horizon as the margin after the strong gravitational pull of the singularity bends space-time.

Outside the horizon, there are normal physical rules that we know, and from the horizon to the singularity, it is in a semi-regular state, where time and space are reversed, there is no size of space, only the process of constantly collapsing from the edge of the horizon to the singularity, and when we reach the singularity, time returns to zero, and any physical rules we know from the outside world lose their meaning.

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

We often say that the speed of light is the fastest speed, and the speed of nothing can exceed the speed of light, not because it is the speed of light, so it cannot be exceeded, but because the speed of light has reached the extreme speed of the universe, it is correct to say that the speed of anything cannot exceed the upper speed of the universe, and this upper speed is numerically equal to the speed of light, that is, the speed of electromagnetic wave propagation. It is also equal to the speed at which gravitational waves propagate.

Black holes can be large and small, and the horizon line of a black hole is exactly the threshold at which an object escapes from its bondage. On the event horizon, the escape velocity of an object is equal to the upper speed of the universe. Outside the event horizon, the object can break free because the gravitational field from the singularity is weakening and the escape velocity is below the upper limit of the cosmic velocity.

In the horizon, because the speed required to escape exceeds the extreme speed that the universe can achieve, the world in the horizon is a world beyond the constraints of its rules for the outer universe, at least the world in the horizon is no longer under the control of the external universe. It's the realm of the singularity.

The distance from the horizon to the singularity becomes a strong wall that prevents the outer universe from exploring the interior.

"The black hole is so powerful, its gravitational field completely destroys the rules of physics as we know it, and the main body of the mother civilization is torn into the black hole, becoming the nourishment of this monster of no size, and falling little by little in the direction of the singularity......"

Hearing this, Su Yuan couldn't help but ask: "Falling in the direction of the singularity, isn't that constantly falling in the direction of the timeline equal to zero?"

Many science fiction movies or novels often use guò black holes to travel through time, which is theoretically correct. Because of the ideal spherical black hole, its event horizon is a complete sphere. If it is continuously divided in the direction of the singularity, then each subtle division is the state of the sphere at different times, and the closer it is to the singularity, the more the division reflects the process of the "object" on the surface of the horizon regressing back on the time axis. i.e. from the event horizon of the black hole to the singularity. It is the process of "upside down" that the "object" on the surface of the horizon has experienced.

As an example, if a person travels from Earth to the black hole event horizon, it is assumed that he is perfectly attached to the surface of the event horizon. Without being torn apart by the gravitational difference of the horizon, then when he crossed the horizon and kept approaching the singularity. In fact, it is a process of leaving the horizon and returning to the earth.

It's like a mirror. We theorize that the origin of the universe was the Big Bang starting from the singularity, so beyond the mirror of the black hole horizon, we return to the singularity at the beginning of the cosmic explosion.

Although there seem to be many black holes in the outer universe, and each black hole has a singularity, in fact, every act of crossing the black hole horizon towards the singularity is an opportunity for us to get closer to the source. Because there are no rules for the singularity, the "supernatural" existence of the black hole itself is that after the gravitational force has developed to the extreme, it breaks the laws of time and space of the external universe, making it present an inverted "image", and these singularities are essentially the source of the external universe in which we live.

Jayne nodded thoughtfully, "Indeed, as you said, if the mother civilization can resist the gravitational difference at the edge of the horizon, they are indeed heading for a passage to travel back in time. However, in practice, this behavior only exists in theory, because any object is spatial, and their size means that they cannot withstand the infinite division of the horizon, so in the process of crossing the horizon and entering the back of time, when the space axis is reversed with the time axis, all objects will be torn into infinitesimal pieces...... Only infinitesimal objects perfectly attached to the surface of the horizon can enter the process of going back in time along the horizon. ”

"Infinitesimal objects, that is to say, do not have macroscopic particles, and can only pass through the horizon if they return to a sufficiently small state, that is, an energy state?"

Su Yuan asked suspiciously.

Jayne Ray said: "The research direction of our Midshrandi civilization is space, and the level we have reached lies in the macroscopic and abstract multi-dimensional space realm. There is not much research on this process of time and space exchange. Not only us, but also the time-based Ophee civilization, which is not much different from our Midshrandi civilization, does not know much about this process of transformation. ”

"Aoife civilization?"

Su Yuan was puzzled by this unfamiliar term that suddenly appeared. And the point is that this Ophee civilization is actually not much different from the Midshrandi civilization, and it is in the direction of the main body of time.

Jaynerui smiled like a spring breeze, as if he had suddenly broken free from the historical situation of the collapse of the mother civilization, and said: "The Aofei civilization is a distant civilization located outside the countless river systems, and when our Midshrandi civilization has developed to the extreme, we learned by chance that this civilization is no less powerful than ours!"

"The main direction of the Aoife civilization is time, and in the realm of time they are omnipotent. Through technical exchanges, there is no superiority or inferiority between our two civilizations in terms of conventional technology, but the main direction of the two civilizations is 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 order of magnitude......!

Because of the technology in this area, the Ofie civilization has far surpassed other civilizations in the life sciences, an ordinary member of the Ofie civilization, the average life expectancy has reached a terrifying 20,000 years, and some key protection scientists, politicians, out of the needs of civilization can be extended to 100,000 years.

In front of the Aoife civilization, the Midshrandi civilization is like a young and energetic guy, and in many cases, the Ofee civilization is taking care of this "newborn" civilization as an "elder" and has achieved good results.

"Haven't your two civilizations had a technological exchange in time and space?"

Su Yuan asked strangely.

"Technical exchanges?" Jayney smiled, "Of course there is, but the ones that are being exchanged are inconsequential non-core ideas, and you must know that no civilization can completely open up its main research to communicate with another civilization." Although the ancient and powerful Aoifie civilization is friendly to us, how can the hole cards be shown lightly?"

In fact, the Ophee civilization that is known for time and the Midshrandi civilization who is good for space are very proud, they both think that only time and space are the most powerful fields of research, when they have achieved good achievements in one of the fields, and push civilization to the extreme, the worship of their own subject research has risen to the top, so they have psychological resistance and contempt for the other field that is completely "unfamiliar".

Rather than taking the risk of researching a relatively unfamiliar technical field that requires huge financial and material resources, it is better to concentrate all your energy on continuing to advance in the field you are good at. You must know that scientists are valuable assets, and they must not be dragged into a crooked path of "slowing down the main body research" by the so-called temptation!

This is not a broom to cherish itself, but in order to meet the unpredictable universe, we must always continue to advance in our own fields of expertise and maintain the advanced nature of civilization. Rashly dividing troops and engaging in other research may hinder the progress of the main body of research.

"Of course, our technological exchanges have also made substantial progress, the Aofi 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 technologies such as time defense shields, stationary field cannons, and wide-area annihilation fields from the Ophee civilization, and have jointly developed ultra-long-distance space-time jump technologies from the two masters...... Tongguò established a star road transfer station to further solve the problem of ultra-long-distance navigation. ”

Speaking of this, Jayne Ray sighed: "At the most critical juncture, it is also the Orphee civilization that saves 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 powerful gravitational field of the black hole, according to the principle of relativity, the time passage in the gravitational region is slow, although only a few minutes have passed from the appearance of the black hole to the collapse of the mother civilization, but for the outside, hundreds of years and thousands of years have passed. ”

"The Aofei civilization, which has close communication with the mother civilization, suddenly found that the message from the mother civilization was interrupted, so it sent a fleet to check, and it was because of the arrival of this fleet that it was able to save some of the personnel of the mother civilization by combining the static field cannon and the wide-area annihilation field. This was the predecessor of our exile branch. ”

"After surviving the exile branch, they witnessed the process of the entire mother civilization being swallowed by the black hole, and then the space collapsed, and the mysterious black hole disappeared after the space collapsed for some reason. (To be continued......)
