Chapter 463

The stars hide in the charming red fog and emit white, blue and red dazzling light, like the Star Gods staring at the people on the ground through their veils.

The savages were still praying, as if the ceremony would never end.

I don't know what kind of fish Ivan roasts. The meat is a little rough and tastes like old beef, but hunger makes people's taste buds bloom like flowers. With salt, the burnt meat taste is comparable to the most delicious meal in the world.

The crow kept quacking while eating: "quacking, it's delicious! This is the best meat I've ever eaten, quacking!"

Su Huilan said with a smile, "didn't you say that nothing is better than your landlady's sauce elbow?"

"One moment at a time, another at a time. If you have sauce elbow now, it must be delicious. If you don't have sauce elbow, you can make do with this meat!"

The crow croaked for two words, and suddenly gave Su Huilan a white look, "Hey, don't think I'm saying you can make do with croaking. For a man in charge, a woman can't make do with it!"

Suhuilan almost choked on a piece of meat in her esophagus. She finally understood a truth. Don't dream of taking advantage of the crow at any time.

She ignored the crow and found that situ and Aoki suddenly stopped talking at the moment, which made the atmosphere a little silent and embarrassing. She wanted to ask situ about the alliance, but she didn't think the time was right. Or there are some uncertain places in her heart. She doesn't want to be led by the nose. The conversation between Aoki and situ just now made her feel that this man was a little unreal. If you talk about her dream, you must talk about a lot of things she didn't want to mention. She didn't want to tell her secret to a person who was so smart and terrible and seemed very untrue before the situation was unclear.

She remembered that the discussion on time and atomic clock had not ended, but was interrupted by Aoki's question. She wanted to continue the question and asked:

"Mr. situ, you just said that you first created a real dream to synchronize the dream with the reality, and then created a cesium atomic clock to time in the dream, but you can't carry an atomic clock in your consciousness all day and keep yourself in a sleepwalking state?"

"Don't be so troublesome," situ said. "I just connect the real scene of the island to the dream, and then determine the cycle of regular events in the surrounding environment, such as the interval between two tides, so I can roughly measure the time corresponding to our world."

Su Huilan remembered the giant moon change she had experienced before and said, "the tide is caused by the gravity of the moon, and the instability of this space shows that it may move between the earth and the moon, which will obviously lead to changes in the tide. How can we infer time through the tide?"

Situ said, "so it's not enough to test once. Once you find that the environment changes, you have to test again. However, you may not notice that the instability of this space does not change at a uniform speed. It is stable most of the time. Otherwise, there can be no civilization on the Island. Unfortunately, the tribal civilization here has been destroyed in the disaster caused by space change."

"So how much time have you measured?"

"About a year."

"Almost a year?" Alice, who was already full, wiped the oil around her mouth with her hand, then shook her head and said she didn't believe it. "I don't understand what you said about the atomic clock. I really can't remember how many days and nights have passed, but I know how many meals I have eaten. Our food is already small. If a year later, I must be a ghost, not a person!"

The crow croaked and nodded in deep agreement: "croak, the crow is starving! The crow is starving!"

Situ Rao looked at the crow with interest. The crow looked unnaturally and didn't turn his head: "all right, all right, stop talking! I'll just eat meat..."

Su Huilan thought for a moment and said, "I once guessed that this is a Klein bottle. Aoki and I have discussed this for many times. Many things have confirmed that my guess may be right.

You and Mrs. Larry entered this space at the same time, but they lived on different islands. According to you, nearly a year has passed, but Alice only feels a few days, which obviously doesn't seem to happen in the same time and space. Your atomic clock is accurate, but the human metabolism and biological clock won't deceive her.

Although the Klein bottle contains part of the four-dimensional space, it is generally closed, and any position of the bottle body is connected. Can we say that we were in the same space but at different times? "

Situ nodded and said, "Professor Su, your guess is right. It can be understood as a Klein bottle, but you ignore that Klein bottle has no fixed shape. We call it a bottle because we can only see its projection in three-dimensional space-time. A real Klein bottle can be of any shape."

Su Huilan thought about the deep meaning of situ's words: "do you mean...?"

Situ reminded, "if you have to imagine, you can imagine that the bottleneck of this bottle is very long, even longer than a giraffe."

"Giraffe?" Su Huilan looked at situ in confusion.

Situ said with a smile, "a neck that grows to light years."

Su Huilan seemed to understand something and suddenly said, "I see. You mean when we are on different islands, we are in different positions on Klein bottles. Sometimes the distance between the two is... In light years?"

Situ nodded: "so I also said that the significance of atomic clock timing is not big. I don't use it to see time, but use it to deduce the position of time and space."

"Why?"

"Because if you are in a spaceship traveling at high speed or even the speed of light, think about what will happen and what is the meaning of an atomic clock?"

"High speed navigation will have obvious relativistic effect." Su Huilan thought of the giant moon she saw that day, indicating that the island was approaching the moon at a very fast speed. She calculated in her mind the speed at that time and the possible relativistic effect.

Aoki's brain suddenly flashed a light, but he didn't remember anything.

He looked up at the clouds in the sky and the shining stars. He had never seen the sky before, but he had an inexplicable sense of familiarity, as if he had stared at it countless times in the past.

Situ also looked up at the sky and said, "look at the starry sky above you. Are you familiar with it?"

Su Huilan studied celestial literature. She suddenly exclaimed, "this... This is the nebula of Orion!"

What's so surprising about the Orion nebula that others don't understand?

Suhuilan excitedly pointed to the magnificent star clusters in the sky and shouted:

"The big bird is the Orion Nebula, which is 1350 light-years away from the earth; the protruding rotating dark cloud is the Horsehead Nebula, which is 1500 light-years away from the earth, and the light behind it is the hydrogen atom cloud ionized by the star; the red arc aperture is the Barnard ring, which has a span of 300 light-years. It is impossible to see these nebulae of Orion on on the earth, which should be seen with the naked eye It's so clear that at least three-quarters of the distance should be pushed forward, that is to say... "

Suhuilan's heart was pounding, and her voice trembled and wondered, "are we on the arm of Orion 1000 light-years away from the earth?"
