Transmigrated as the Crown Prince

Prince Oscar started the propulsion program of "Star 1", and the spacecraft began to fly around the earth.

Because Germany has launched several experimental communication satellites, even if "Star 1" flies to the other side of the earth, there will be no communication interruption problem. Although there was some interference, you could still clearly hear Prince Oscar sighing about the beautiful scenery of the earth outside the window.

After a while, he seemed to have discovered something quite novel. "Strange, why can't I see the stars?"

In later generations, a very interesting question circulated among space enthusiasts: Can astronauts see stars in space?

At first glance, this seems like a silly question. Most of the stars that can be seen at night are stars, and stars are stars that can emit and heat themselves. How could you not see them? Yet the question is raised again and again, not just by moon-landing skeptics and fringe science advocates, but also by the general public who seem to have learned somewhere that stars cannot be seen in space.

The origins of this misunderstanding are often traced to an interview with the Apollo 11 astronauts, in which Neil Armstrong allegedly said that he could not see the stars in space.

But what actually happened was that several astronauts were discussing the inability to see stars from the daytime side of the moon. As for why no stars can be seen during the day on the moon but the sky is dark, that is because the moon has no atmosphere, so there is no scattering effect when sunlight shines over it, so the sky is dark; and because the sunlight is very bright, of course It blocks starlight, making it impossible to see the stars.

There are also some photos taken in space. The background is black and no stars can be seen. This is because when you take a close-up photo of a bright object such as a planet or moon, you won't have an exposure long enough to clearly see the faint starlight. The most important thing to capture the stars in any photo is the exposure setting. For example, on a dark night, you can see thousands of stars outdoors (on Earth), but if you just pick up your camera or mobile phone and take a quick picture, all you will get is darkness.

Therefore, if you want to photograph stars in space, you need to use time-lapse photography. The shutter needs to be open for several minutes or even hours to allow enough photons to hit the film to obtain images of the stars.

Yannick picked up the microphone and explained casually. "That's because the sun's rays are now shining directly on the spacecraft, covering up the starlight, so of course you can't see it. You will be able to see the stars when the spacecraft enters the dark side of the earth."

At this time Dr. Obert reminded. "Your Highness Oscar, in five minutes you will see the sunset in space."

"Oh? Then I have to appreciate it." Five minutes later, His Highness Oscar said speechlessly. "Haha, this is too fast, the sun goes down like this!"

The alternation of day and night in space is different from that on Earth. The alternation of day and night on Earth is a slow process, while the alternation of day and night in space can be described as lightning-fast. Because the spacecraft flies very fast, when the spacecraft flies from the yin side to the sun side, the sun "jumps" out all of a sudden. When the spacecraft flies from the sun side to the yin side, the sun disappears like a "whirlwind". If the spacecraft orbits the Earth at a speed of 90 minutes, the astronauts on the spacecraft can see 16 sunrises in 24 hours.

But his attention was immediately attracted by the scenery outside the window, and he sighed from the bottom of his heart. "So many stars, it's really a sea of ​​stars!" Because there is no air in space, and there is no scattering and refraction of the atmosphere, astronauts can see more stars than on the earth, brighter, and no flickering; this situation can only be To describe it as spectacular.

Yannick continued casually. "So our journey is the sea of ​​stars. Sooner or later we will leave the cradle of the earth."

Little Elizabeth asked suddenly. "Brother Yanik, even if we enter the space age, human strife will not stop, right?"

"Yes." Yannick couldn't help but smile bitterly. "Disputes are shackles that humans can never get rid of. Religion, ideas, resources, land, resentment, love, whims...these boring reasons can all be called excuses for disputes. Unless one day human beings collectively evolve into saints who have no desires or desires. "But the so-called lack of desires and demands is tantamount to the eradication of "real" human nature, turning it into a physical hard drive that stores human memories. That is to say, there is memory in the brain, and it looks like a human being, but it has lost all the characteristics of human nature and has become a walking corpse. It feels weird to think about it. "However, humans cannot be bound to the cradle forever, and leaving the earth is an inevitable trend."

The great theoretical physicist Stephen Hawking has broken down the threats that could lead to the extinction of the human race. He believes that there are many possibilities for the demise of mankind, among which the most talked about are "artificial intelligence", "human conflict" and "alien civilization".

The overwhelming number of science fiction films of later generations have described various "artificial intelligences" and "alien civilizations". Most of these "artificial intelligences" and "alien civilizations" are hostile to human beings and will never give up until they eliminate human beings. Hawking believes that even if "artificial intelligence" and "alien civilization" do not destroy mankind, human civilization may destroy itself and end in its own internal conflicts. Human selfishness, greed, and uncontrolled expansion, as well as scientific and technological progress, have also created weapons that can destroy mankind. "The risk of life on Earth encountering devastating disasters is increasing, such as sudden global nuclear war, genetically engineered viruses, or other dangers we have not yet imagined." Among them, global nuclear war is taking shape among human civilizations. It creates a terrifying and strange deterrent, which is the most worrying.

Faced with such threats, Hawking believes that space exploration and space immigration are the most ideal solutions. After all, the earth’s resources are limited, and extending human living space and resources to outer space is indeed the only way to continue human civilization.

At this time, Prince Oscar's voice sounded again. "We are almost over the American continent." A ray of sunlight in the early morning shone on the North American continent, allowing him to clearly see the outline of the continent. "Do you want to say hello to these Americans?" The communication between "Xingchen 1" and the launch base is in an encrypted frequency band. Even if the signal is captured by other radio equipment, it is just irregular noise, but he still You can use clear communication to say hello.

Yannick smiled. "Forget it, so as not to scare those poor guys." So far, they have launched several satellites. Yannick thinks that the Americans should have discovered that there are more of these things in the sky, and guessed that it was Germany's method. However, these Americans probably never dreamed that they could send a living person into space and fly hundreds of kilometers above their heads.
