The stars hide in the charming red fog, emitting white, blue, and red dazzling light, like star gods looking at people on the ground through the veil.

The savages are still praying, it seems that this kind of ritual will never end.

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

The crow kept croaking as he ate, "Crack, it's so delicious! This is the best meat croak I've ever eaten!"

Su Huilan smiled and said, "Didn't you say that nothing is as good as your wife's elbow in sauce?"

"At this moment and then, if you have sauce elbows now, the sauce elbows are sure to be delicious. Without sauce elbows, this meat can be quacked!"

The crow croaked a few words, and suddenly gave Su Huilan a white look, "Hey, don't you think I'm saying that you can also quack, for a man in charge, a woman, it is impossible to quack!"

Su Huilan almost choked on her esophagus. She finally understood a truth, don't try to take advantage of this crow at any time.

She stopped paying attention to the crow, and found that Situ and Aoki suddenly stopped talking, and the atmosphere seemed a bit silent and embarrassing. She wanted to ask Situ about the alliance, but she felt that the timing was inappropriate. Or maybe there are still some uncertainties 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 is a bit unreal. If she talks about her dreams, she must talk about many things she doesn't want to mention. She didn't want to reveal her secrets and details to someone who was terribly smart and seemed extremely unreal before the situation was still unclear.

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

"Mr. Situ, you said just now that you first created a real dream to synchronize the dream and reality, and then created a cesium atomic clock in your dream to keep time, but you can never carry an atomic clock in your consciousness all day. Let yourself be sleepwalking, right?"

"Don't be so troublesome." Situ said, "I only need to connect the real scene of the island to the dreamland, and then determine the period of regular events in the surrounding environment, such as the interval between two tides, and then I can roughly measure the difference between here and Our world corresponds to the time."

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 cause the tide to change. Use tides to guess time?"

Situ said: "So one test is not enough. Once you find that the environment has changed, you have to test it again. However, you may not have noticed that the instability of this space does not change at a constant speed. It is stable most of the time. Yes, otherwise there would be no civilization born on the island, but it’s a pity that the tribal civilization here was destroyed in the disaster caused by spatial changes."

"So how much time has passed since you measured it?"

"It's almost a year."

"It's almost a year?" Alice, who was already full, wiped the oil from her mouth with her hand, and then shook her head to express her disbelief, "I don't understand what you said about the atomic clock, and I really can't remember it. It has been a few days and nights, but I know how many meals I have eaten. Our food is already scarce. If one year has passed, then I must be a ghost now, not a human!"

The crow quack nodded deeply in agreement: "Quaqua, the crow is starving! The crow is starving!"

Situ took a look at the crow with interest, and the crow turned his head unnaturally when he saw him: "Okay, okay, let's not talk about it, you guys chat! I just eat meat..."

Su Huilan thought for a while and said, "I once guessed that this is a Klein bottle. I have discussed this with Aoki many times, and many things have happened to prove that my guess may be correct.

You and Mrs. Larry entered this space at the same time, but they lived on different islands. According to your statement, time has passed almost a year, but Alice only feels a few days later, which is obviously not like what happened in the same time and space. Your atomic clock is accurate, but the body's metabolism and biological clock will not deceive her.

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 at different times? "

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

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

Situ reminded: "If you have to imagine it, you can imagine the bottleneck of this bottle as long and long, longer than a giraffe."

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

Situ smiled and said, "A neck that is long enough to use light years."

Su Huilan seemed to understand something, and suddenly said: "I see, you mean that when we are on different islands, we are in different positions on the Klein bottle, sometimes the distance between the two is...in light years count?"

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

"why?"

"Because if you are in a spacecraft traveling at high speed or even the speed of light, think about what will happen, what's the point of the atomic clock?"

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

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

He raised his head and glanced at the clusters of nebulae in the sky and the shining stars in them. He has never seen this sky, but he has an inexplicable sense of familiarity~lightnovelpub.net~ as if staring at it countless times in the past.

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

Su Huilan has studied astronomy, and she suddenly exclaimed: "This...this is the Nebula of Orion!"

Others have yet to understand, what is so surprising about the Nebula in Orion?

Su Huilan excitedly pointed her fingers at the magnificent star clusters in the sky and called out:

"The big bird is the Orion Nebula, which is 1,350 light-years away from the earth; the raised, rotating dark cloud is the Horsehead Nebula, which is 1,500 light-years away from the earth, and the light behind it is a cloud of hydrogen atoms ionized by stars. ; The red arc-shaped aperture is Barnard’s ring, which spans 300 light-years. It is impossible to see these nebulae in Orion on the earth. To see such a large and clear with the naked eye, at least it has to advance by a quarter. A distance of more than three, that is to say..."

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