Dream Guide

The stars hide in the charming red mist, emitting dazzling white, blue, and red light, as if the star gods are watching the people on the ground through a veil.

The savages are still praying, as if this ritual will never end.

I don’t know what kind of fish Ivan grilled. The meat is a bit rough and tastes like old beef. But hunger makes people’s taste buds bloom like flowers. Plus there is salt. The taste of this burnt old meat is comparable to the world’s most delicious. A delicious meal.

The crow kept croaking as he ate: "Quack, quack, it's so delicious! This is the most delicious meat I've ever eaten!"

Su Huilan smiled and said, "Didn't you say that nothing can be as delicious as your boss lady's sauce elbow?"

"One moment, another moment. If there is soy pork elbow now, it will definitely be delicious. If there is no soy pork elbow, this meat will just make do with it!"

The crow croaked a few words and suddenly rolled its eyes at Su Huilan, "Hey, don't think I'm saying that you can just make do with it. For a responsible man, women can't just give in!"

Su Huilan almost choked on a piece of meat and couldn't get it down her esophagus. She finally understood the truth: never try to take advantage of this crow in your mouth.

She no longer paid attention to the crow, and found that Situ and Qingmu suddenly stopped talking at this moment, and the atmosphere seemed a bit silent and awkward. She wanted to ask Situ about the alliance, but she felt that the time was not right. Or maybe she still has some uncertainties in her heart, and she doesn't want to be led by others. The conversation between Aoki and Situ just now made her feel that this man was a bit unreal. If he talked about her dream, he would definitely talk about many things that she didn't want to mention. She didn't want to reveal all her secrets to a person who was horribly smart and seemed extremely unreal before the situation became clear.

She remembered that the discussion about time and atomic clocks was not over yet, but was interrupted by Aoki's question. She wanted to continue this question, so she asked:

"Mr. Situ, you just said that you first created a real-life dream to synchronize the dream and reality, and then created a cesium atomic clock in the dream to keep time. However, it is impossible for you to carry an atomic clock with you in your consciousness all day long. Let yourself be in a sleepwalking state?"

"It doesn't have to be so troublesome." Situ said, "I just need to connect the real scene on the island to the dream world, and then determine the periodicity of regular events that occur in the surrounding environment, such as the interval between two tides, and I can roughly measure the distance between here and The time that our world corresponds to.”

Su Huilan thought of the giant moon changes she had experienced before and said: "Tides are caused by the gravity of the moon, and the instability of this space shows that it may move between the earth and the moon. This will obviously cause the tides to change, so what? Determining time based on tides?”

Situ said: "So measuring once is not enough. Once you find that the environment has changed, you have to measure again. But one thing you may not have noticed is that the instability of this space does not change at a uniform speed. It is stable most of the time. Otherwise, there would be no civilization on the island. It is a pity that the tribal civilization here was destroyed in the disaster caused by space changes."

"Then how much time did you measure?"

"Probably almost a year."

"Almost a year?" Alice, who had already eaten, wiped the oil around her mouth with her hand, then shook her head in disbelief, "I don't understand what atomic clock you are talking about, and I really can't remember it. Several days and nights have passed, but I know how many meals I have eaten. Our food is already scarce. If a year has passed, then I must be a ghost now, not a human being!"

The crow croaked and nodded in deep agreement: "Caw quack, the crow is starving to death! The crow is starving to death!"

Situ glanced at the crow with interest, and the crow looked away unnaturally at his glance: "Okay, okay, let's not talk anymore, you guys can chat! I'll just eat meat..."

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

You and Mrs. Larry entered this space at the same time, but lived on different islands. According to you, almost a year has passed, but Alice only feels that a few days have passed. This is obviously not like what happened in the same time and space. Your atomic clock keeps time accurately, but your body's metabolism and biological clock don't fool her either.

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

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

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

Situ reminded: "If you have to imagine, you can imagine that the neck of this bottle is very long, longer than a giraffe."

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

Situ smiled and said, "A neck as long as light years."

Su Huilan seemed to understand something and suddenly said: "I understand. You are saying that when we are on different islands, we are at different positions on the Klein bottle. Sometimes the distance between the two is... light years." count?"

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

"Why?"

"Because if you were in a spaceship traveling at high speed or even the speed of light, think about what would happen. What's the point of an atomic clock?"

"High-speed sailing will have obvious relativistic effects." Su Huilan thought of the giant moon she saw that day, indicating that the island was approaching the moon at an extremely fast speed. She mentally calculated the speed at that time and the possible relativistic effects.

A flash of inspiration suddenly flashed in Aoki's mind, but he didn't think of anything.

He looked up at the clusters of nebulae in the sky and the bright stars twinkling among them. This sky was something he had never seen before, but it felt inexplicably familiar to him, as if he had stared at it countless times in the past.

Situ also raised his head and looked at the sky and said, "Look at the starry sky above your head. Does it look familiar?"

Su Huilan had studied astronomy, and she suddenly exclaimed: "This... this is the nebula in the constellation Orion!"

Others haven't figured it out yet. What's so surprising about the Orion Nebula?

Su Huilan excitedly pointed at the magnificent star clusters in the sky and shouted:

"The big bird is the Orion Nebula, which is 1,350 light-years away from the Earth; the protruding rotating dark cloud is the Horsehead Nebula, which is 1,500 light-years away from the Earth. The light behind it is a cloud of hydrogen atoms ionized by stars. ;The red arc-shaped aperture is Barnard's Loop, which spans 300 light-years. It is impossible to see these nebulae in Orion from the earth. To see them so big and clear with the naked eye, you have to travel at least a quarter of the way. A distance of three or more, that is to say..."

Su Huilan's heart was beating loudly, and her voice was trembling and uncertain, "We are now on the Orion cantilever, which is 1,000 light-years away from the earth?!"
