Earth Era

?As Zhao Lan thought, Lobachevsky space is just a space in mathematical concepts, it is a space described by Lobachevsky geometry. ←, There are many peculiar phenomena in this space. For example, in this space, the pi is larger than the normal space, and the sum of the interior angles of the triangle is smaller than the normal space. At the same time, in Roche space, at least two parallel lines can be made by passing a point outside the line, and a circle may not necessarily be made by passing three points that are not on the same line... and so on.

This was originally just a concept in mathematics, but in this record, Li Yunfan said that he found such a space in the real cosmic space, and confirmed it through field measurements.

If normal space, that is, the space described by Euclidean geometry, is flat, then the space described by Lobachevsky geometry is "curved". If a space is curved, it seems reasonable that the stars that can be observed in normal space cannot be observed in such a space. Zhao Lan can imagine such a picture. Because of the curvature and curvature of space in Roche’s space, some space parts may be hidden due to the “folds” of space. The light of the stars does not completely travel along the space, but directly. After crossing this folded space, it spreads directly to the other side of the fold. Then people who are in the space between the folds will naturally not be able to see those stars.

It was like a river or a ditch appeared in the space. The light is the animal jumping directly over the ravine or the river. It jumped directly over, and did not come to the bottom of the gully along the wall.

As for why the farther the stars disappear sooner, this can be explained by the curvature of space. A two-dimensional plane can be compared to space. But not exactly. The properties of space cannot be fully described by a two-dimensional piece of paper. Zhao Lan guessed. The farther the stars are from the Earth, the greater the curvature of space, so they are more likely to disappear from Earth's view.

"Could it be... at this moment our earth is in the Lobachevsky space?" Zhao Lan thought silently, "However, the measurement of geometric data we have made on the earth or on Mars Nothing unusual was found."

As long as this argument can be confirmed, that is, as long as people really find the pi or the change in the interior angles of a triangle compared to previous data, people can really prove it. And the angle of space curvature can be calculated through the numerical differences that produce specific changes, and then the perfect space model around the earth at this moment can be calculated through Roche geometry. If this can be done, then the mystery of the disappearance of the stars will be solved.

"But we still don't have any evidence." Zhao Lan shook his head, put aside the thoughts in his mind, and continued to read the information.

Li Yunfan continued to write in this document: "After confirming this, I immediately guessed that this should be a Lobachevsky space in our universe. In mathematical calculations, Roche's geometrical All theorems have been perfectly verified in this space, and all the experimental and observational data are telling that this space is different. I don't know where this strange space came from and how it was born. Yes - it may have been born in the infinite depths of the universe, due to the war of some super civilization or some special physical process of the cosmic environment. Who knows - does not know what age it was born in. It may be It has been in a drifting motion, and has been drifting in the endless universe for thousands of years before it drifted into our solar system. I was finally discovered by a very accidental opportunity.”

"Roche space is not the same as normal space. According to this principle, spacecraft and mechanical equipment suitable for normal space should not be able to exist in Roche space. The simplest example, due to the change of pi, can be normal in the past. The running **** or bearings may become less rounded in the Roche space, and the friction force will increase greatly, which will eventually lead to mechanical damage. However, through my personal experiments, my spacecraft can still be normal in this piece. Running in a strange space. I guess, this is probably because the spatial data changes are too small, and our current mechanical technology is far from reaching that precision, so it will not cause us to be observable. Influence."

Zhao Lan thinks this guess is very logical. This is like a child who randomly uses three wooden strips to make a triangle, because the triangle made out of three wooden strips is originally inaccurate, so even if the sum of the interior angles of the triangle is adjusted to 181 degrees, it will Probably will not have any effect on this triangle.

The mechanical technology of human civilization and the mechanical precision that can be achieved, to a certain extent, is actually similar to a child using three wooden sticks to make a triangle at random. There is no essential difference between the two. Therefore, the changes in pi and many other spatial data did not have any intuitive impact on the spacecraft Li Yunfan was riding at that time.

"The very existence of Roche space seems to suggest the feasibility of navigating through the curvature of space. After all, if light can go directly over some folds of space without going completely down the space - which is the reason why being in Roche When in space, the phenomenon of the abnormal disappearance of distant stars - then we humans should also be able to create spaceships that can cross the folds of space through technological means. This seems to point out a way for human civilization to create superluminal spaceships."

"I and the team of scientists I led were very interested in this, so we began to focus our scientific research efforts on this aspect, and went all out to study this strange space."

So far, Li Yunfan's written descriptions and records are followed by many mathematical model descriptions of the space, descriptions of physical properties, some conjectures, and many calculation processes. Although Zhao Lan has some knowledge in this field, but with that knowledge, he can't fully understand the calculation process. So Zhao Lan can't understand these things too well.

But even with Zhao Lan's scientific literacy, Zhao Lan can see that... these calculation processes are very profound and complicated, and each step is connected naturally and logically. Such a piece of information, even if you want to fake it, requires extremely advanced professional knowledge as a basis. Ordinary people, or even ordinary scientists, can't do it even if they want to make such a fake.

Zhao Lan went through the calculation process, and then saw that the writer of the follow-up research records changed from Li Yunfan to Rodriguez. Obviously, after Li Yunfan disappeared, the research on this strange space did not stop. Under the leadership of Rodriguez, this team of scientists, who was out of sight of the human government, continued to carry out research on it.

Zhao Lan naturally knew where Li Yunfan went. A few months ago, when Li Yunfan was driving his Sylvia spacecraft back to Earth, perhaps because of the influence of the final explosion of Haishan Er, Li Yunfan inexplicably traveled from this universe to another universe, that one. The universe has nothing but darkness, and Li Yunfan has been trapped there, unable to escape...

The subsequent records written by Rodriguez recorded some research results of their team of scientists on this strange space after Li Yunfan disappeared. The most important record is that they found that since the explosion of the Haishan II supernova, the space curvature of this strange space has begun to increase abnormally for unknown reasons, and the volume has also begun to expand rapidly, even covering the entire earth. inside. And the structure of the strange space has undergone more complex changes than before. The team of scientists led by Rodriguez is intensively calculating and observing the possible impact of this change in the strange space on the earth, but So far, they haven't found anything concrete.

The team of scientists led by Rodriguez did not know what impact this strange space had on the earth. Zhao Lan, a member of the 105 Research Institute, knew it very well. Distant celestial bodies continue to disappear abnormally~www.readwn.com~, and the distance between the observable disappearing celestial bodies and the earth is getting closer and closer... This is the most intuitive manifestation of this effect.

The closer the observable anomalous disappearing star is to the Earth, the greater the curvature of the space in which the Earth resides. When the curvature reaches a certain level... Maybe it will really be like what happened to Li Yunfan, the passage between the two universes will be opened up, and the earth will fall from this universe to that completely empty universe. Since then, it has been blocked by darkness and loneliness. Human civilization will step into space, and the road to enter the interstellar era will be completely cut off. Human civilization will be trapped there alive after exhausting all the resources of the earth...

The scene seen from the perspective of the earth is that the stars in the sky disappear one by one, and finally there will be no bright spots in the sky. Can't see any stars either...

This strange space is not just a space as simple as that. It is a bottomless abyss that is enough to destroy a planet and destroy the entire human civilization in despair. It is a sharp sword hanging over the heads of all human beings.

Facing this possibility, Zhao Lan felt a little shudder. (To be continued..)
