When other roads were not accessible, the top scientists among human beings at that time pinned their hopes on the "space leap" technology.

For a long time, this technology was regarded by the entire human civilization as the hope of overcoming obstacles to the scale of the universe and marching into the depths of the universe.

At that time, some scientists predicted that if a severe breakthrough was not achieved in "space leap", human expansion would reach its peak in about 100,000 years, and then encounter an obstacle that human technology could not overcome in any way, and eventually it would perish due to the drying of resources. Of course, there must be a prerequisite, that is, within these 100,000 years, human beings must defeat all alien civilizations they encountered.

There is no doubt that the scientists' prediction is absolutely unfair.

The basis of this prediction is that the diameter of the Milky Way is about 100,000 light-years, and the star system closest to the Milky Way is tens of thousands of light-years away. For example, the Big Magellanic System is more than 100,000 light-years away from the Milky Way, and the Little Magellanic System is more than 200,000 light-years away from the Milky Way. More importantly, this is the extra-river star system that orbits the Milky Way, also known as the dwarf star system, or the "satellite" of the Milky Way. Between the two star systems, there is a desolate space, and no spaceship built by humans can cross such a long distance. More importantly, there is no danger before the star system, which is completely impossible to prefabricate.

In reality, there must be danger.

For example, when studying the Small Magellan Galaxy, scientists came to an extremely important conclusion, that is, there is more dark matter in the Small Magellan Galaxy than in the Milky Way. The theory of gravity field has pointed out that dark matter that cannot be observed by humans is actually space energy. In other words, the space energy in the Small Magellan Galaxy is much higher than that in the Milky Way.

Obviously, this is not a scientific conclusion that can make people happy.

You should know that the visible matter in the Small Magellan system is only 2% of the Milky Way, and its disturbance on the formation of the Milky Way is nearly forty times that of its visible matter. From this we can calculate that there is a large amount of dark matter in the Small Magellan system, and its total amount is far greater than that of the Milky Way.

So what imagination will arise if dark matter, or space energy gathers in large quantities?

Scientists cannot give an accurate answer, and can only be sure, that is, the physical environment in the Small Magellan Galaxy is likely to be different from the Milky Way. To put it more indirectly, even if human spacecraft enters the Small Magellan Galaxy, they may not be able to sail normally.

In a sense, the extra-river star system is a dangerous place.

Of course, there is no shortage of star systems like the Milky Way in the vast universe.

According to scientists' estimates, although the number of dwarf star systems is much larger than that of star systems, in the universe, even if there are not one trillion star systems, there are still one hundred billion, and the physical environment of these star systems is very similar to that of the Milky Way.

The problem is that these Milky Way-like star systems are too far away from the Milky Way.

Recently, it is also 100 million light years away!

What is this concept?

Even if the energy of the spacecraft is not a problem, the time the astronauts spend in the frozen state is equivalent to ten thousand years under normal conditions!

Obviously, under normal circumstances, humans cannot live for ten thousand years.

Besides, to fly to the next Milky Way, it will take 100 million years to use the current technology of human beings, and in 100,000 years, human beings will face the big problem of lacking living space.

So, why do scientists worry too much?

First of all, it is impossible for humans to fill the Milky Way within 100,000 years, because the sun is located at the edge of the Milky Way, and the nearby star systems are far apart. In the center of the Milky Way, stars are relatively close. Some star systems are less than a light year away and are almost next to each other.

Second, scientists have proved that the sun is a "small star" in the Milky Way, and the number of planets it has is relatively small in the Milky Way. Among the star systems discovered at that time, most of the stars were surrounded by ten, even dozens of planets, and there were many terrestrial planets.

Third, there are about 120 billion stars in the Milky Way, about one-tenth of which is similar to the sun, which can provide humans with an appropriate living environment. If calculated based on the fact that there are two to three terrestrial planets around each such star, there are tens of billions of terrestrial planets in total.

Obviously, in the next 100,000 years, the scale of human beings will not expand by tens of billions of times, and there will be no survival crisis.

Finally, the speed of human scientific development is an acceleration model, that is, technological progress is getting faster and faster, so no one can guarantee that humans will still be limited by the speed of light in 100,000 years.

The problem is that this prediction still has a large market in human civilization.

To put it bluntly, human beings are a civilization living in the sense of crisis, and it is also the crises that constantly emerge that make human beings move forward desperately.

This dim future prediction spurs the entire human civilization.

At that time, for many people, 100,000 years was not a long time. You should know that some astronauts who explored the Milky Way in theory could exist for one million years, or even two million years, because of the Tremite.

Most of our lives are spent in a frozen state.

In other words, before these explorers explored the entire Milky Way, humans were probably dead.

Of course, this is also an unreasonable worry.

But whether it is not an unfair worry, this paranoid prediction triggered the second technological outbreak in the universe era in human civilization.

For a moment, almost the entire human race began to work hard for survival in a hundred thousand years.

However, the scientists' research results are still extremely pessimistic.

In theory, folding three-dimensional space can definitely be done, but the energy required exceeds the ability of humans and even exceeds the sum of all energy mastered by humans. The main reason is that humans themselves live in three-dimensional space and are three-dimensional intelligent living organisms. Therefore, if you want to fold three-dimensional space, you must first deal with the problem of space energy overflow generated during folding, and this also depends on energy.

At that time, scientists gave a conclusion: unless the three-dimensional space of the universe is originally distorted and there are overlapping points in some places, humans will only have the ability to fold the three-dimensional space after they have escaped the constraints of the three-dimensional space, that is, they will become four-dimensional intelligent life bodies.

In reality, this is a very easy-to-understand concept.

For example, if there is a two-dimensional intelligent life form on a piece of paper, no matter how you fold the paper, the intelligent life form does not know that the space it exists is distorted. Only when you occasionally reach a certain crease and suddenly enter another area of ​​the paper will you find that its space has been folded and can indirectly go from the crease to another very far away place.

The same is true for humans living in three-dimensional space.

As a result, some scientists began to look for "stack points" in the universe.

Of course, these scientists firmly believe that the three-dimensional space of the universe is definitely not absolutely flat, but a very distorted three-dimensional body. Therefore, there must be some stacking points in the universe, and these stacking points will become the basis for humans to overcome spatial distance.

In fact, this idea is easy to understand.

Similarly, using paper as an analogy. If you apply a drop of glue on a corner of a square piece of paper and then bond to the opposite corner, the paper will be twisted, and the two-dimensional living organisms living in this piece of paper can indirectly reach the other corner of the piece of paper from the bonding point.

So, what is this bonding point in a twisted three-dimensional space?

At first, scientists believed that it was a celestial body with super mass, such as a black hole. Because in the eyes of scientists, the supergravity generated by a black hole, or the large amount of space energy gathered, is enough to distort time and space, and then connect with another distant space. Subsequently, scientists linked the black hole with a opposite celestial body, namely a white hole, and believed that black holes and white holes are two ways of expressing the bonding point of three-dimensional space. Of course, this also explains why black holes are constantly absorbing energy, while white holes are constantly releasing energy.

However, it was not long before the scientists overturned the argument.

The reason is very simple. No matter how strong the space energy of a black hole is or how much energy the white hole releases, the effect of both is inside the three-dimensional space and cannot transcend the three-dimensional space. Therefore, the spatial distortion caused by it cannot transcend the three-dimensional space itself.

To put it indirectly, as long as internal factors cause distortion of three-dimensional space, it is impossible to overlap three-dimensional space.

Now, the problem arises.

The upside is that humans do not have to take risks to explore black and white holes, because if the universe itself is an extremely distorted three-dimensional space, then when it is formed, the stacked part already exists, and it may not exist in some extremely terrifying way. Maybe somewhere that humans have explored, a bridge connecting two distant spaces is formed in an extremely ordinary way.

The bad side is that such bonding points cannot be found by humans as known detection methods.

After all, humans can only rely on luck to find such bonding points.

The problem is that in the vast universe, even within the scope of human activities, the places where human footprints go are only one trillionth of the space area.

In other words, the probability of human beings "winning" is only one in one trillion.

Obviously, if we really want to place our destiny on luck, we may have to sit back and wait for death.

Fortunately, humans are both creatures with strong sense of crisis and optimistic creatures.

Scientists' discovery is equivalent to telling anyone that since the opportunity exists, then hope exists. If the total human population is divided by probability, there will always be a few people who will become lucky. Even though this is a mathematical fallacy, it still gives trillions of people a huge hope.

With hope, human behavior often becomes extremely crazy.
