"Frank, I'm not denying the necessity of the Interstellar Immigration Program!" Commander Hobart shook his head and continued, "The Interstellar Migration Project is indeed the last resort to ensure the continuation of the spark of civilization on Earth! However, I really don't feel the need to organize such a large-scale interstellar migration operation. Pen, fun, pavilion www. biquge。 infoI think it's enough to build 10 space cities. We should concentrate our resources on more cost-effective [Geocentric City] projects! ”

"Hobert, with all due respect, I think you're biased." Frank had a serious expression on his face, "How to save the earth's civilization and overcome the apocalyptic crisis is a deep test of the wisdom, thoughts, humanity, and soul of all mankind, not just a survival investment considering cost performance." In the incomparably vast space of the universe, in the face of severe living environmental conditions, how can 10 space cities, with a population of only 300~5 million, ensure the smooth inheritance and continuation of the earth's civilization? ”

"You must have heard this ancient old Oriental philosophy, [I have an end to my life, and there is no end to knowledge, and there is no end to it, and there is no end to it, and it is gone! 】。 There is a limit to every human being's life, ability and knowledge. All walks of life, every field of science, need a sufficient population base to support and seek development. You must be well aware that if the total population falls below 100 million, the scientific, humanities, and artistic systems of human civilization will be irreparably damaged, and it may not be able to recover to its current level for hundreds of years. ”

"Frank, are you so unconfident in the Underground City's crisis defense system!!" Hobert shouted indignantly.

"Nope! I'm not questioning the crisis defense system of the underground city. In fact, I'm desperate for the Underground City's defenses to be able to stop the Gamma Ray Burst from attacking. However, we are scientists, we must be fully and adequately prepared, and we must not leave even the slightest chance in our hearts, which is the responsible approach to the earth's civilization!! ”

"But ......"

"That's it! I already see both! No need to argue any more! ”

As the commander-in-chief's tone was sonorous and his voice sounded, a powerful aura instantly enveloped the entire conference room, immediately ending the dispute between the two.

"The details will be decided after I discuss them with the leaders of various countries."

The Commander-in-Chief said unquestioningly, while Hobert and Frank remained silent.

......

In August 2079, the Mirai spacecraft was about 1 light-year away from the solar system.

This year, Yuan Haochen, a core member of the Interstellar Exploration Alliance, is 49 years old, and Smith is 54 years old, and they are expected to arrive on Earth in a year.

In the vast, dark, deep cosmic space.

The Mirai spacecraft was still like a lone leaf, floating in the inky water, silent, without the slightest ripple.

Looking out of the porthole of the Mirai spacecraft, it is a very strange and magnificent visual feast.

As the Future is flying at 79% of the speed of light, the scenery outside the porthole has seen a very strong and strange visual effect.

What does the view look like when moving near the speed of light?

Although the scenery of the universe is relatively monotonous, the picture outside the porthole is still heavily distorted (the closer we get to an object, the farther away it looks). At the same time, the objects on either side of us will be distorted. The whole starry sky looks as if it is crowded in front of us.

Then, the Doppler effect kicks in and changes the color of the objects around us.

According to the Doppler effect, when flying close to the speed of light, the frequency of the electromagnetic waves in front of you will move like the blue end of the electromagnetic spectrum, and a blue shift phenomenon occurs, that is, the scene we observe in front of us will be blue, and some electromagnetic waves that originally belong to visible light will exceed the range of visible light. Conversely, some infrared light will also become visible light due to its increased frequency, which means that the scene seen by the human eye will be closer to that seen by colored infrared telescopes.

The simple description is to turn things near us blue and distant things red.

In addition, objects in front of us will appear to be moving faster than they actually are, and objects behind us will be slower. Objects on both sides appear to be bent, and objects that are not visible under normal conditions are on the side or even on the back. are likely to enter our field of vision.

In the lounge of the Mirai spacecraft, Yuan Haochen was looking into the distance with great attention, and silently recited in his heart: "I left the earth in February 2062, and it has been exactly seventeen and a half years now......

The near-hometown is more tangible, which is the psychological portrayal of Yuan Haochen at this time.

Perhaps because he was about to return to Earth, during the month of adjusting and recovering after waking up, Yuan Haochen often recalled the bits and pieces when he left Earth.

At this moment, his mind was still replaying the video message he had just watched, which was an email from the Earth Command Center a year ago.

His father's concerned face, his mother's loving smile, and the blessings of his former colleagues and friends lingered in front of Yuan Chen's eyes for a long time.

"Twenty years from now, if I could return to Earth without any problems, what would I be like, what would my family and friends be like, and what would Earth be like?"

This is the question that Yuan Haochen pondered when he left the earth.

Time is fleeting, youth is scarred, looking back on the past, years are hard to find.

Life is like flowing water to the east.

With the passage of time and the changes of the years, the sword of time has already left obvious marks on everyone's body.

However, Yuan Haochen was already strongly aware that his timeline had distanced itself from them very significantly.

From the perspective of general relativity, although Mirai and Earth use the same time scale, because Hara and Smith are flying at sub-light speeds or even close to the speed of light in a spacecraft, the flow rate of time has changed subtly, so their aging rate is actually much smaller than that of their family and friends on Earth.

In addition, in interstellar travel, they hibernate in hibernation chambers for a long time, which further slows down their aging rate.

Therefore, whether it is Smith or Yuan Haochen, the age that looks like is much younger than it actually is.

Especially Yuan Haochen, it is exactly the same as when he first left the earth!

Although a similar situation happened to Smith, the traces of the passage of time can still be detected from Smith under careful observation.

It's truly an incredible thing!

Yuan Haochen had discovered the abnormalities of his body a few years ago, and he also imagined several possibilities from a scientific point of view, but in the deep space of the universe, the conditions were limited, and this puzzle had to wait until he returned to Earth in the future to verify it.

"Hello Earth, see you next time you wake up!"

After collecting his thoughts, Yuan Haochen turned around and walked to the hibernation module, preparing to enter the last hibernation of this interstellar journey.......

Volume II, Star Traveler, end.

ps：

In this story, Yuan Haochen and other outstanding scientists dedicated their most precious youth to save the earth civilization, and opened the prelude for the earth civilization to enter the era of interstellar exploration.

I believe that after the earth civilization survives this apocalyptic crisis, it will definitely usher in a new golden age!

Finally, a little bit of a mention.

The table of contents for the next volume is: The Fall of the Earth.
