Outside the training base of the National Space Center in Xiaguo.

Liu Peiqiang looked at the data displayed on the tablet, and with Fan Fangsi's inquiry, he had a feeling of confusion, the Wandering Earth Project really couldn't succeed?

"If the Wandering Earth Project cannot be successful, why did the coalition government develop the Wandering Earth Project?" Liu Peiqiang asked directly.

Before Fan Fangsi answered, Liu Peiqiang continued, "Since you can think of a question that the coalition government can't think of, are you smarter than the experts in the world?" ”

Fan Fangsi responded calmly, "The coalition government knows. ”

"Huh?" Liu Peiqiang thought about how Fan Fangsi wanted to explain, and also thought about Fan Fangsi to quibble, but he didn't think about Fan Fangsi directly admitting it.

"As you said, I'm not the only smart person in the world, the coalition government has brought together experts from all over the world, and they naturally know that the Wandering Earth project is bound to fail." Fan Fangsi explained.

Liu Peiqiang took a deep breath and forced himself to calm down, "Since the coalition government also knows that the Wandering Earth plan is bound to fail, why gather the world's strength to promote the implementation of the Wandering Earth plan?" ”

Fan Fangsi pointed to the sun in the sky, "Do you know what happened to it?" ”

Liu Peiqiang frowned, isn't this matter well known?

"The Sun is about to enter old age, and according to experts' speculation, it will enter the red giant phase in about a hundred years, so that it will expand rapidly and swallow the Earth into it." Fan Fangsi recounted the situation.

"According to this situation, if you don't start the Wandering Earth Project, waiting for the end of the Earth is certain death." Fan continued, "Although the Wandering Earth Project will definitely fail, once the Wandering Earth Project is launched, we will win at least a thousand years. ”

"This period of time is extremely precious, we can use this time to develop more advanced technology, such as space technology, if we can develop spacecraft, we can collect meteorites, asteroids from outer space on the road, so as to fuel planetary engines." Fan Fangsi explained.

"Although the results of the Wandering Earth project are terrible, and according to the current situation, it is doomed, but it can give us enough time to delay, which is the ultimate goal of the coalition government." Fan Fangsi analyzes the purpose of the coalition government.

Liu Peiqiang pondered for a moment before responding, "If it's to stall for time, the coalition government has a better choice!" ”

"For example?" Fan Fangsi asked rhetorically.

Liu Peiqiang responded, "When the sun transforms into a red giant, it does expand in size, but after we install a planetary engine on the earth, we can completely move the earth's orbit outward, so that the earth still revolves around the sun that transforms into a red giant." ”

Liu continued, "With this method, we can delay for a longer period of time and obtain a more stable living environment, so as to provide better conditions for scientific research." ”

At first glance, Liu Peiqiang's plan does seem to make some sense.

The biggest threat to the Earth from the rapid decay of the Sun into a red giant is to swallow up the Earth's orbit after its size expands, but moving the Earth's orbit outward seems to solve the problem, right?

"To borrow your previous words to reply to you, you are not the only smart person in the world, and the problems you can think of, the experts of the coalition government can think of 100 percent." Fan Fangsi responded.

Liu Peiqiang was silent, he still felt that there seemed to be no problem with the suggestion he made.

Fan Fangsi didn't sell it, he explained, "In fact, it is indeed as you said, if you just move the Earth's orbit outward, it is far lower than the Wandering Earth Project in terms of technical difficulty, and you can also obtain a relatively stable development space." ”

"But here's the problem!" "Our Sun has undergone an anomaly, and under normal circumstances, it would take five billion years for it to age into the life cycle of a red giant. However, at present, it is about to enter the life cycle of the red giant in about 100 years, in this case, how can we judge whether it is stable after entering the red giant stage? ”

Judging by the normal red giants observed in astronomy, it has a period of 'relatively short time' of stability, which is about millions of years relative to the billions of years of the star's life cycle.

For humans, a few million years is definitely enough.

Suppose the sun decays into a red giant star and can be stable for millions of years

No!

Even if the stability period is only 10,000 years, Fan believes that the coalition government is willing to stay, and the big deal is to change the orbit of the earth, so as to keep the earth away from the red giant, and then find an orbit to survive, which is not a difficult thing.

However, the current sun has completed its lifespan of about 5 billion years in just 100 years or so, and this anomaly has caused the coalition government to worry that the sun will also have a similar anomaly in the red giant stage.

Once such a similar anomaly occurs in the red giant stage, and the red giant formed by the sun explodes directly as a supernova, won't the earth be gone?

A supernova explosion is one of the highest horror events in the universe!

If the red giant formed by the sun has a supernova explosion and the earth is not far enough, then the earth will not be tougher than a blank sheet of paper in a supernova explosion event, and it will be torn into powder by the supernova explosion.

The coalition government does not dare to gamble, after all, this kind of gambling is to put the fate of all mankind on the gambling table, once it loses, all mankind will perish, and the human race on the earth will completely disappear.

In order to avoid such a thing, the coalition government would rather pay a huge price to implement the Wandering Earth project, even if the Wandering Earth project is a broken plan, but the coalition government still promotes this plan.

Everything is for the sake of the continuation of the human race, so as to make a forced choice.

Liu Peiqiang had a feeling of sudden realization, but he had a new question, "Since you know these things, what is your purpose in looking for me?" ”

"Would you believe me if I said I didn't have any purpose?" Fan Fangsi asked rhetorically.

Liu Peiqiang obviously didn't believe it.

Fan Fangsi chuckled and said, "I really don't have any purpose. Okay, Mr. Liu Peiqiang, thank you for chatting with me, I will heal your wife, goodbye. ”

After finishing speaking, Fan Fangsi's figure suddenly disappeared.

"Huh?" Liu Peiqiang looked at the place where Fan Fangsi disappeared in shock, he quickly looked around, there was flat ground all around, there was no hiding place at all, if he didn't still have a cup of Starbucks coffee in his hand, he would have to wonder if he was hallucinating?
