Voyage of the Stars.

Chapter 716 No accident
A theory is considered correct if it can explain actual universal physical phenomena, not all phenomena in all fields. Just like classical mechanics, it cannot explain phenomena in the quantum field, but it is still correct for phenomena in the macroscopic world.

In various mechanical relationships involved in daily life and even in calculations of planetary gravity, humans still use classical mechanics equations. These things are the same whether on Earth or elsewhere in the universe.

The same is true of the theory proposed by human scientists today. It is not applicable to the various mechanical relationships involved in daily life, but it is applicable to the black hole photon sphere environment and even the event horizon environment, so in this respect it is equally applicable to any black hole.

This is the isotropy of the universe. No matter where you are in the universe, the physical rules are the same. Of course, artificial changes do not count, just like the pioneers' diamond crystals told humans that quantum entanglement could be used for long-distance communication but cannot be used now. This is the result of interference from a god-level civilization.

If the pioneers had not left this message, the civilizations born in the Milky Way or in the large star regions near the Milky Way would not know about it. In this case, one day when they traveled to other areas where the rules of quantum entanglement may not have been modified, they would doubt the principle of spatial isotropy that they have always believed to be correct.

Once this principle is overturned, the cosmic view of this civilization will undergo a drastic change, which may very likely cause this civilization to give up on itself, believe that exploring the unknown is futile and ultimately perish. Of course, it is also possible that this civilization will go down another path and give birth to another extreme cosmic sociology.

Time flies, and forty years have passed in a flash. If it were in the Earth era, such a long time would be enough for a person to experience vicissitudes of life. However, in today's human society, a forty-year-old must still be in school. To normal people, it is just a flash of time.

However, during this period, humans did complete the exploration of this black hole. Not all of it, but all of it within the scope of their own technological capabilities. The theory of the physical rules of the black hole photon ball also evolved from its infancy to a relatively complete theory during this period.

At the same time, humans have obtained forty years of close-range black hole observation data.

Both theoretical and actual detection data are human wealth. Although human technological creations cannot currently cross the innermost stable circular orbit, cannot truly set foot inside the photon sphere, let alone step into the event horizon and the inside of the black hole, these data will also lay a solid foundation for humankind's subsequent exploration of black holes.

This kind of experience and data from close-range exploration of black holes can be easily obtained by wandering civilizations, of course, they also need to be lucky enough to encounter a black hole during their cosmic travels, just like humans. Or they can go on a long voyage to explore black holes. If settled civilizations want to obtain this data, they must form a long-distance fleet to travel to star regions thousands of light years away.

Take humans for example. If we could stay on Earth forever, then if we launched a black hole exploration scientific research mission, we would have to form a large fleet and travel 2,800 light-years away to reach the nearest black hole.

Obviously, it is difficult to achieve navigation technology at the third-level civilization level, because it means a voyage of more than 6,000 years, after all, the time for supply and maintenance must be taken into account, and it may take even longer if some cosmic emergencies occur.

Only a Level 4 civilization can effectively carry out long-distance voyages of this magnitude.

But on the other hand, as long as civilization wants to progress, as long as civilization wants to continue to improve its technological level, long-distance voyages are necessary. Even if the main civilization does not go, it must send out scientific research fleets to explore, because perhaps the seeds of some advanced scientific and technological ideas are hidden in a special celestial body in the vast sea of ​​stars.

Perhaps the proposal of some scientific and technological theory requires close observation of black holes or other special celestial bodies to obtain relevant data. This black hole exploration not only allows humans to obtain tangible scientific data, but also makes human leaders realize the value of this data. The leaders even think that if there is really such a legendary fair interstellar trading market, then these observation data may be sold.

Where there is market demand, there will be related products.

Just like what people know as longevity potions, alloy materials, scientific and technological information, technological creations, biosphere resources and the like, after all, information can become a commodity. Humans still remember selling false information to the Nair civilization.

Even so, humans actually have a good impression of the Nair civilization, which is the first civilization of the same level that has lived in peace with humans. Unfortunately, the starry sky is vast, and it is difficult to meet again since they parted years ago. Moreover, humans have now left the Orion Arm, making it even more difficult to meet.

But it doesn't matter. Now there is also a Nair civilization among humans. Of course, they are not the real Nair civilization. It's just that these Nair people still miss their original civilization, so they didn't change the name of the civilization.

Having said that, during these forty years, apart from exploring black holes, humans have been docking in nearby star systems to replenish various resources. After forty years of stable development of human civilization and even the entire Star Alliance, the ships are filled with various supplies, and various matters related to the establishment of the Star Alliance have also been improved in these years, so it is time to set off again.

The destination has not changed, and we are still heading towards the location shown on the star map along the originally planned route.

This is the last leg of the journey. After setting off, the Star Alliance, led by human civilization, is extremely cautious. Every time they arrive at a star system, there will be an exploration team to explore the way first. These are the exploration missions undertaken by the member civilizations of the Star Alliance. There are also exploration spacecraft patrolling the route of the large fleet.

These tasks are now mostly carried out by the member civilizations of the Star Alliance. They are like the marching scouts of the Star Alliance, traveling between the Star Alliance fleet and the exploration area. With their constant patrols, the vision of the Star Alliance fleet is greatly increased, and the possibility of being attacked by other civilizations is minimized.

The performance of the Star Alliance, also known as the Star Covenant, led by humans, already seems to have some of the qualities of a cosmic force.

The road to the stars is long, one light year after another, hundreds of light years after hundreds of light years. As the distances are crossed, the planned route has been traveled by humans for the first half. The journey here is no different from the previous journey. We still haven't encountered other civilizations, nor have we encountered planets with life.

This feeling is great. As long as the last 800 light years of travel can be maintained, humanity's journey across the spiral arm will be perfectly completed.

But there is no coincidence in the world.
