Long-distance interstellar journeys are tedious and adventurous. The computer of the Pen Fun Pavilion www.biquge.info tells the astronauts a touching story related to dreams: Lucy, the daughter of Professor Mary of the Institute of Aerospace Special Materials, falls in love with the young White Cloud Knight from the East, but the outbreak of the First Star War breaks them apart, and the White Cloud Knight leaves his beloved to go to war as an astronaut. Since then, Lucy has been looking forward to the end of the interstellar war as soon as possible so that she can tie the knot with her beloved. Just 35 Earth days before the end of the interstellar war, the blonde Lucy was haunted by a nightmare: in the darkness of the "Dead Planet", she was blocked by a huge rock in a place from which she could not escape. He tried to push away the boulder next to him, but couldn't. His look of despair was etched in Lucy's memory......

Lucy wondered about the dream, but couldn't tell why. By the summer of the following year, Lucy was still dreaming about it, in which she saw a large part of the castle of the "Dead Planet" collapse and the exit to the castle blocked—the wreckage of the spaceship hit by the laser cannonball was scattered around. She also heard the White Cloud Knight's cry for help in her dream. The dream continued day by day, and finally one day, Lucy decided to find the "castle of death" in this dream to see what was bothering her.

Lucy pilots the expedition ship into the blue sky and begins the search for the castle of the "Dead Planet". However, she didn't know whether this "Castle of Death" was on the Moon, Mars, or the "Castle of Venus" or some other planet, so she could only search aimlessly. The hardships she went through in the search process can be imagined.

One day on another 35th Earth day, Lucy's expedition spacecraft came to a landing site in the Martian Arctic space space, and a migrant "castle" appeared on the top of the mountain in front of her, and she was so excited that she excitedly shouted: "I've seen you, I've seen you countless times in my dreams!" The Martian settlers were surprised by this uninvited guest, and they curiously followed Lucy to the place where the "Castle of Death" had fallen. She begged a few Martian "men" to help remove the collapsed rocks, but found nothing. The local Martian immigrants heard Lucy tell her about the dream, and although they all thought it was a little funny, they didn't want to break the heart of a pure girl, and still came to help her carry the stones the next day. Just as the sky was getting dark, people were surprised to hear a man's cry for help under the stones. Soon they got a man out of the ice cave

Come out. That person was none other than Lucy's boyfriend, White Cloud Knight.

It turned out that the White Cloud Knight used the castle as cover in the battle with the subordinates of the queen of the "Dead Planet" who came to invade, but the laser shell hit the castle and the spaceship, blocking the place where he was hiding. After the battle, he was not found. Thankfully, there was food and water in the ice cave, and he stayed like this for two Martian years, until Lucy came to his rescue.

Who made Lucy dream this? How did she dream of this Martian "castle of death" that she had never seen before? This matter feels a little mysterious, but it can't deny its authenticity. Therefore, we can only say: dreams, it's amazing!

In the western suburbs of Houston there is a white "space hospital" named Alamaida. One night, Dean Johnson dreamed very clearly that a space shuttle had crashed near the hospital. After waking up from the dream, he thought that this possibility existed, so he began to prepare an emergency training and rescue plan in an extraordinary situation overnight, and quickly handed it over to the hospital for implementation. In the spring of the following year, a space shuttle from a naval base unfortunately fell next to the hospital, and a few minutes later, the hospital's ambulance team arrived at the scene and quickly deployed the rescue as usual, everything was carried out in an orderly manner. After timely rescue, although 7 people died and 5 were injured in the end, if it were not for the emergency training plan of the dean's dream, the death toll of this accident would definitely have increased greatly. This is a good thing that Dean Johnson has done because he believed in the dream, and everyone has praised it.

Also one day 40 years ago, the "ageless" residents of Space City's improved genes gathered in the gymnasium to hold a memorial ceremony to commemorate the "wormhole" faster-than-light spacecraft that went missing in the air crash on the Orion A Red Starfish expedition, and it was reported that all three astronauts on the spacecraft, two men and one woman, were killed, and none of them were spared. According to custom, one of the families of the missing astronauts, Tu Long Yunfei (Fei) and his family kept vigil all night. Fleisisco always believed that the woman he loved was still alive, because Yun Fei (Fei) always dreamed of the woman he loved before returning from training every time, and this time he had the same dream. I don't know if it's the fate arrangement in the power, or something else. According to some hint in the dream, he was determined to be ordered to investigate the planet Red Starfish in Orion A and the planet of the Sea in Y Cygnus (Gliese 163f), and the Red Starfish was a no

There is a water planet with land and the seasons are not very obvious, and the living environment of the earth is very different. "In fact, water as a substance makes up a fairly small percentage of the total material on Earth. There are roughly several sources of this water: primordial dust formed by Earth, interstellar water molecules captured over decades, and ice core moisture from asteroids or comets that hit Earth. It is these extremely complex sources that come together to form the moisture that is now on Earth. The weight of surface water is less than 6/10,000 of the weight of the earth, and there is basically no water in the earth's core, and in order to measure the condition of the mantle, in 2002 AD, Japanese researchers created four compounds similar to mantle minerals in a high-temperature and high-pressure environment, and then poured water on these compounds to test how their weight changes after absorbing water. The results show that the amount of water dissolved at the mantle is five times as much as the amount of water at the surface

Many. So the weight of surface water plus the weight of mantle water, the proportion of water to the weight of the earth is about one thousandth. This is a very low percentage, and we can imagine planets with a much higher proportion of water or ice cores, and theoretically it is not even possible to rule out planets that are 100% made up of water or ice cores, and some asteroids and comets have similar proportions. Logically, then, it is also a rare event that on all planets where liquid water or solid ice cores are present, the proportion of water is less than one thousandth of its weight. Ninety-nine of a hundred such planets may be ...... larger than Earth's Mercury."

The black Adan listened in a daze, and the little mermaid Princess Qian'er was rarely silent.

Flessisko smiled and said, "Don't look at me like that, you must know that my major is astronomy, and my graduation thesis was the study of extraterrestrial water-bearing planets, and the title was 'Water Planet' - I was also the lord of the underwater kingdom of Atlantis...... Let's get back to the point, and even at a low percentage of one in a thousand, the oceans take up most of the Earth's surface. If we assume that the water weight of a planet is 2/1000 of the total amount of the planet, then according to the general principle, it is unlikely that continents will exist, and individual islands may exist, but if the proportion of water on planets rises a little more, they will disappear completely. That is, it is reasonable to assume that for all planets where liquid water exists, the existence of large areas of land is only a small probability event, and the surface is basically covered by oceans

It's the norm. In fact, of the more than 200 extraterrestrial life planets discovered by humans so far, only one planet has a large land mass. ”

"Where?" Princess Qian'er, the Little Mermaid, couldn't help asking.

"It's the blue starfish of Y Cygnus, where I've lived for nearly forty years. Ninety percent of its surface is covered by oceans, and it has a continent the size of the country of Atlantis. When it was first discovered, the attention it attracted was unprecedented, and the Earth Council activated the most urgent plan. ”

"Why? Just because it has land? Adan Chimed In, a black man.

"Could there be any other reason? It's because of the land. Fleisisco nodded affirmatively...... (To be continued.) )
