Most of the members of Blue Home belong to the "Homeland faction", believing that the crossing technology will be successfully developed, and have also provided large sums of money to the "101 Project" in the past, and are very enthusiastic about the progress of the project.

Seeing Wu Haibo present, everyone gathered around and asked about the current status of the "101 Project".

"With your strong support, the 101 project has indeed made a breakthrough, and I believe that after a while, the experts of our project team will be able to come to the Blue Home in person to inform you of the good news."

Wu Haibo smiled and said, "Since today is a film and television appreciation meeting, let's talk more about movies, this film just now is really magnificent and heart-wrenching, but do you think it is really feasible to fill the earth with engines, push the entire planet off orbit, and push it on a journey spanning tens of millions of years?" ”

Everyone glanced at each other, knowing that the appearance of the crossing expert could not be as simple as just talking about the plot of the movie.

Meng Chao also pondered the deep meaning of Wu Haibo's question.

After a while, Wu Haibo himself revealed the answer: "Movies are just fictional art, and the 'planetary engine' seems spectacular, but it is difficult to turn it into reality."

"First, the Earth, and most of the theoretically habitable planets, must be rich in liquid water and atmosphere, and the land is a suspended plate, and if you think of the earth's crust as an eggshell, the whole planet is egg whites and egg yolks.

"The planetary engine is like a needle tip, poking heavily on the eggshell, the biggest possibility is not to push the whole egg forward, but to directly puncture the eggshell, that is, the plate is torn, floods, earthquakes, volcanic eruptions, and all kinds of devastating natural disasters have come one after another, and it is not at all that the underground shelter can resist.

"Second, according to the analysis of the thrust of the planetary engine and the resources consumed, the idea of reaching the new home in thousands of years is too good, in fact, this journey is very likely to be extended to tens of thousands of years, and before reaching the new home, all the resources on the earth will be exhausted, and it will become a gradually cooling dust in the dark universe.

"Third, even if you are lucky enough to arrive in a new galaxy, a massive celestial body like the Earth will be integrated into the orbit of the galaxy's celestial body, and it is very likely to change the orbit of the original planet of the galaxy, causing immeasurable consequences - the orbits of the two planets are staggered, attracting each other or even colliding fiercely, which is a high probability event.

"Therefore, although the 'Wandering Earth' project is romantic, it is unlikely to become a common method of starry sea navigation for a cosmic civilization.

"Please let go of the wings of your imagination and imagine if a civilization is advanced enough to fly freely from one side of the universe to the next, what kind of vehicles are most likely to be used, planets or starships?"

Everyone talked for a while, and a young man wearing a black military uniform on Earth said: "Since it is not feasible to use planets as vehicles, it seems that there are only starships?" ”

"That's right, the planet is too big, and it takes too many resources to propel a planet into space, and the consequences are unpredictable, and if it weren't for the critical situation in the movie where the stars are going to expand in a short period of time, it doesn't seem like there's a need to gamble."

Wu Haibo said, "Compared with using the entire planet as a vehicle, using a starship for interstellar navigation is a more conventional and technically easier idea to implement."

"But Starships have their own problems.

"The size of the starship is simply too small.

"Human beings, or carbon-based intelligent life, are creatures that originated on the planet, and they are born with the need for vast space and a wide variety of resources in order to expand their civilization.

"In the vast sea of stars, even the earth itself is just an insignificant speck of dust, not to mention a starship that is hundreds of millions of times smaller than the earth, and it is not even a bacterium or virus.

"It's hard to imagine that a civilization can colonize another planet on the other side of the starsea with just a few hundred starships.

"Even, on a scale like a starship, it's hard to even maintain the essence of civilization."

Meng Chao understood what Wu Haibo meant.

Just like the "Dragon King Town" that Ye Xiaoxing once introduced, on the scale of a town or a starship, it is extremely difficult for human civilization to maintain the law, morality, life and reproduction methods of the Earth Age.

Earthlings who leave the earth, riding on a narrow starship, and the dark and cold universe, separated only by a fragile shell, are destined to be constantly eroded by the darkness, and gradually alienated into another civilization, another creature, is a "cosmic person" rather than a "earthling".

Of course, as long as you can build a huge starship, the kind that can fit an entire city into it, maybe you can solve the problem of "civilization alienation".

But with the current technology of the people of Dragon City, it seems that the creation of such a super starship is even more distant than the success of the research and development of controllable traversal technology.

"The size of the planet is too large, and the size of the conventional starship is too small, is there a relatively compromise vehicle that can carry the spark of civilization and spread to the entire sea of stars?"

Wu Haibo smiled slightly and threw out the answer, "Actually, there is, and that is the city."

"Cities are the crystallization of civilization, and all the production, organization and warfare of human civilization revolve around cities, and in many language families, 'city' and 'civilization' are originally the same word, and only when archaeology discovers a specific city-state, people can confirm the real existence of a civilization.

"If in ancient times, there were many human beings living in villages and mountains, then, with the high degree of organization of human civilization, social production activities and people's lives are becoming more and more concentrated in highly developed large cities.

"It is completely conceivable that when the civilization of a planet develops to the extreme, more than 90% of its population, science and technology, and social production activities are all concentrated in a few super cities.

"In terms of the mass of the entire planet, megacities and civilizations probably account for less than one percent.

"Ninety-nine percent of the remaining mass, with the exception of a very small number of farms, breeding farms, and mineral veins, mountains, rainforests, deserts, and oceans are of near-zero significance to civilization.

"If a civilization wants to spread to all corners of the starry sea, there is no need to promote the quality of the entire planet like in the film, it only needs to build the core of the most essential civilization, the city, into a super starship that can travel hundreds of millions of light years."

This whimsical way of astronautics stunned everyone.

Meng Chao's mind was racing, but there was a spark of excitement in his eyes.

"The benefits of turning a city into a supership are clear."

Wu Haibo continued to say quietly, "First of all, the size of the city is large enough, at least millions to tens of millions of civilized individuals, enough to maintain the morality, law, and way of life of civilization on the home planet, and ensure that the spirit of civilization will never deteriorate - at least for hundreds of years.

"Secondly, the construction of the city is basically completed, and after it comes to the other world, it is not necessary to start from scratch and rebuild it again, but it is very convenient to expand to the four fields of the other world, as long as enough resources are found, it can expand in geometric progression, even if other intelligent life is found, there is enough volume to communicate or suppress, and finally, the fire of civilization will be burned to the entire alien star.

"Third, the 'fuel' consumed to push an entire city is astronomical, which is much more convenient than pushing a planet, and the mass of a city alone is unlikely to cause the orbit distortion of the entire galaxy, which is relatively controllable and safe.

"To sum up, I personally believe that when a civilization masters the ability to sail in the star sea, especially the space shuttle technology beyond the speed of light, it will definitely build their city into a super starship, or expand the super starship into a city, and the line between the two will become more and more blurred, and eventually, the two will become one."

When he said this, except for Meng Chao, someone finally reacted.

The strategic analyst from the Exotic Research Institute said thoughtfully: "Researcher Wu, do you mean that our Dragon City is a starship of the primeval civilization?" ”

Wu Haibo smiled slightly: "The time has not come, I didn't say anything, today is a film and television appreciation meeting, I just felt it after watching the movie, and I just talked nonsense with everyone."

"Hypothetically, I mean hypothetically, Dragon City is really a starship of the ancient civilization, but it is very reasonable to explain the reason why Dragon City will cross to the other world, because this is originally the mission of Dragon City, and the so-called crossing is just a voyage according to the predetermined route."

"But—"

One stone stirred up a thousand waves, and many of the core members of the Blue Home became excited, and said, "How is this possible, it is understandable to use a planetary engine to propel a planet, and it is unthinkable to teleport a city unscathed to a foreign land countless light-years away, right?" ”

"It sounds a little incredible, but Dragon City has indeed crossed over.

Wu Haibo shrugged his shoulders and said, "Perhaps, in the eyes of a civilization with the ability to sail in the starry sea, the boundary between mass and energy is not so clear, and the entire city is purely energized, and then transmitted to another coordinate in the three-dimensional space through the fluctuations of the high-dimensional space, and then 'materialized and unfolded' again-who said that the primeval civilization could not create such a miracle?"

"The facts are in front of us, we earthlings are not much different from the monsters of the other world at the genetic level, we can breathe the air of the other world, be infected with the virus of the other world, feel the warm light of the stars of the other world, and cultivate the mysterious energy of the other world, which shows that the crossing is not random, this is our 'destination'."

This problem has been plaguing the earthlings since the beginning of the crossing.

At this moment, it also aroused the whispering of the core members of the Blue Home.

Meng Chao raised his hand and said, "Researcher Wu, every brick and tile in Dragon City was built by us earthlings, and it is impossible for us to give Dragon City the ability to shuttle through high-dimensional space!" ”
