At this time, a person cleared his throat, it was Ye Guangli who was wearing a pair of reading glasses.

He is only fifty-two years old, but his hair is gray, and half of his head is bald. Maybe it's an illusion under the lights, but this half of the bald head looks even brighter.

In the past, most of these images were scientists or old pedants.

Indeed, as a senior astronaut, Ye Guangli is also an old pedant.

Sometimes, he feels like he knows his student well.

Adolf has been engaged in research since his doctoral years, and after more than ten years of getting along, he has a great understanding of his personality, living habits, and "skills" in astronautics.

Sometimes it feels strange, but when did this strangeness begin?

He wasn't sure either, but it probably started with Adolf's disapproval of "excessive" exploration of outer space. Perhaps, he no longer bothered with why this happened.

Thinking of his most proud disciple openly arguing with him is somewhat unpleasant.

"Don't worry, everyone has their own ambitions."

While Ye Guangli sighed, he could only comfort himself like this.

"Aerospace is a great undertaking. In the past, it was based on the development of a country. Now, it is based on the development of a coalition government. Its ultimate purpose is to benefit all mankind and is a cause developed for the future of mankind. ”

Because of speaking hard, Ye Guangli's reading glasses slipped down, and he reached out to help him.

"As a professor of astronautics, I can tell everyone here that our daily work is very boring. Unknown space maps, unknown coordinates, and distance numbers of several light-years or tens of thousands of light-years are really abstract. ”

After Ye Guangli finished speaking, he pointed to his bald head very seriously and said, "This is the best example." ”

Everyone was amused by his humor, and the atmosphere in the conference hall was a little more lively, not as tense as it had just been.

Adolf nodded solemnly.

Yes, as a professor of astronautics, Ye Guangli is definitely competent. He loved the aerospace industry and devoted his life to it, even at the cost of his life.

"But sometimes, our work is fun and challenging. We explore space, we explore the universe, and we turn the unknown into the known. In the past, we were like ants, crawling from the earth and little by little into space. It has realized 'one small step for mankind, one big leap for civilization'. Now, we have speedy ships, exploration ships, and the ability to travel through the vast universe at will. What a huge step forward! ”

Ye Guang used his strength to tap on the table to express his excitement, which could also be seen from his expression.

"So," Ye Guangli glanced at Adolf again, "In the face of the vast universe, the aerospace industry needs a bright light to guide it, that is, a long-term vision, not just limited to the development of the earth itself." ”

Adolf knew that the former mentor was intent on attacking him. He clearly remembered that Ye Guangli criticized himself more than once for being short-sighted and not having the pattern that an astronaut should have.

In the same way, he has defended more than once, that is not short-sighted, but prudent.

Because Adolf believes that while every step taken in the space industry is human progress, it can also be one step closer to a crisis.

Human civilization is developing rapidly, but after all, we know very little about the universe, and we don't know if there are extraterrestrial civilizations and how to deal with them.

The slightest carelessness is the end of humanity.

He believes that this is a rigorous scientific attitude and a responsibility to mankind. Moreover, he also believes that Ye Guangli's view is not called long-term vision, but should be called "ambition".

"Professor Ye," said Adolf respectfully, "although you are my mentor, I think it is more appropriate to call it on this occasion. ”

Ye Guangli nodded with a smile and said, "Adolf, although our master and apprentice have different views, we both contribute to the aerospace industry. Perhaps, I was a little too you in the past. ”

Adolf was stunned, not understanding the true intention of Ye Guangli's words.

He hurriedly adjusted his mentality and continued: "I know that Professor Ye is blaming me for not having a long-term vision, but I accept it with an open mind. However, I would like to express the point that the pace of human space should not be too large, and what we know about the universe now is only the tip of the iceberg, and we are not yet able to cope with the occurrence of unexpected situations. ”

"What kind of contingency do you mean?" Ye Guangli asked.

"Invasion of an alien civilization." Adolf said categorically.

"We are now not sure whether there is an extraterrestrial civilization, and we cannot conclude whether it is higher than human civilization, and we can only get the answer through exploration."

"But, Mentor," Adolf habitually said, "our space industry has developed on the shoulders of human safety, and we have no chance of trial and error. Otherwise, we're going to fail, and I don't think we can afford that......"

"Your point of view is still to build a 'base'?"

Ye Guangli's tone also softened, and it seemed to be Adolf's casual word "mentor".

"Yes, we first established the base, and at the same time realized the migration of part of humanity. In this way, our warships will have sufficient logistical support, and also leave a back road for humanity, at least a back road. ”

Adolf said that the place suddenly became heavy, and continued: "If possible, build more than one base. ”

"But do you know how many years it takes to build a 'base'?"

Adolf said that he really couldn't give a specific or approximate number of years.

"Like you said, we're making extremely slow progress on Mars. Fifty years have passed, and our base has not yet been established, and immigration is far away. If human beings still build the so-called base at this rate, I am afraid that the earth will no longer exist and mankind will have perished! ”

Adolf felt that there was some truth in what he said.

According to the current transformation schedule, it will take at least three hundred years to realize the plan for Martian settlement.

However, the Earth will never last that long.

"So," Ye Guangli said solemnly in an accentuated tone, "we should not focus on establishing a base, but on finding a base." ”

After saying that, he took a deep breath, which was in line with the point of his article.

Loud!

The chamber fell silent for a moment, and then boiled.

When they figured out what Ye Guangli meant, everyone was shocked, and a word came to everyone's minds.

Yes, it is the war that has taken place countless times between various countries - aggression.

Will it be staged in the interstellar arena in the near future?

The reason why human beings built the "dome", the protective shield of the earth, is to avoid being attacked by alien civilizations. This is the masterpiece of the "cautious faction", one of the two existing factions of mankind, and the representative figures are Zhang Tianlin, Adolf, Zhou Ran and others.

Their view is clear: humanity should "develop itself and guard the planet". For the exploration of outer space, we must be cautious and try not to come into contact with extraterrestrial civilizations, so as not to invade the earth.

And on the opposite side is the "expansionists" represented by Williams, Ye Guangli, Zheng Dashen and others.

Their views are also intuitive, believing that the ecological environment of the earth has endangered the survival of human beings, and advocate "exploring outer space, conquering the universe", and looking for a second earth, so that human civilization can be preserved.

The two factions have been formed for a long time, and they have been fighting each other for nearly a hundred years.

At the last debate, the "cautious" faction prevailed, and the coalition government adopted its suggestion to design a "dome" using the most advanced technology of the time in order to protect the planet.

However, with the rapid development of human civilization, resources are extremely depleted and the environment is seriously damaged, which has caused irreversible damage to the earth.

Although the "expansionists" did not gain the upper hand, people became suspicious of the "cautious factions" and gradually showed their dissatisfaction.

Everyone in the conference hall understood what Ye Guangli meant, but because that word was too sensitive, no one said it.

Adolf was also thinking about whether to pick it out.

At this time, Zhang Tianlin suddenly said: "I think everyone understands Professor Ye's point of view, the so-called search for a 'base', I think everyone knows very well." ”

He paused and looked around the chamber.

"To put it bluntly, it's an alien invasion and the establishment of a colony. Professor Yip, am I expressing it accurately? ”

"Hehe," Ye Guangli smiled slyly, "I can understand what Dean Zhang meant, but he misunderstood me a little. ”

Although his views are different, Ye Guangli still maintains respect for the leadership.

"As I said in that article, once we find a 'base', we will not exterminate the indigenous people. It's about living in harmony with them, establishing good order, and then becoming a 'second earth'. ”

"Professor Ye can imagine that if an alien warship lands on Earth and lands on our homeland, will we be able to live in harmony with the aliens?"

"I can't answer this question, there are too many uncontrollable factors......"

"If you follow your point of view, this issue has to be considered, I dare to conclude," Zhang Tianlin paused for a moment, "war is absolutely inevitable. ”

"I don't think it's possible to break out an interstellar war, and our first means is communication."

"Communication? Hehe......"

Zhang Tianlin sneered.

"When it comes to the survival of the race, no one compromises easily. Interstellar war, humanity can't take this risk yet. ”

"Should humanity wait for the destruction of the earth and do nothing?"

Ye Guangli asked sharply, with a rare ferocity in his eyes.

"Everything has its own laws of development, and the universe has its own rules of operation. Human beings, as an insignificant member of this, should move forward according to the laws of nature, not break the rules. Space technology must be developed and the earth must be saved, but I think the most important thing is to start from human beings themselves, human beings themselves! ”

People began to whisper, not understanding what Zhang Tianlin meant by "human beings themselves", and even Zhou Ran and Adolf did not understand what he was going to say.

Once again, the chamber was boiling.
