Chapter 511

Ramra's nest

"You're all right. That's the problem," situ said, "The speed of waves is also limited, and every wave takes time. The maximum speed driven by curvature is ten times the speed of light, but we are now a thousand light-years away from the earth. If my conscious atomic clock is correct, a year has passed since we were in the southern Pacific Ocean. That is to say, in a year, we have moved to A thousand light-years less, our speed is a thousand times the speed of light, far greater than the theoretical maximum of curvature propulsion. "

"Maybe your atomic clock is out of order!" said the crow.

"That is, the earth has passed a hundred years, or even longer," situ said.

"Er..." the crow thought of Ruhua, who was more than a hundred years old, making sauce elbows for it with a crutch, quickly shook his head, and then said solemnly, "after the careful evaluation of the undergraduate crow, your atomic clock is still very accurate!"

Situ laughed and said, "thank you for your assessment, scientific crow!"

Alice said thoughtfully, "so could it be a wormhole? Did we jump in space?"

Su Huilan said: "Anyone who tries to cross the wormhole will die in the trap. Theoretically, only the wormhole connecting the black hole and the white hole can cross. Matter will be sucked in at the end of the black hole and ejected at the end of the white hole. Let alone whether there can be a black hole on earth, even if there is an unstable wormhole in a certain location in the South Pacific, we will be caught by it when it opens Capture, then our bodies will be torn to pieces when we enter the horizon of the black hole. Unless all we have left is a consciousness, and our nervous system may not have time to perceive the fact that we have been torn, so we still think we are alive. "

This sounds a little scary. Although Boris is a big old man, he can still understand such words as being torn by a black hole and dead. He pinched his face hard, cried out and said, "no way! I can still feel pain!"

Situ smiled: "Yes, we all live well, there is no doubt about that! Even if there are stable wormholes that can be crossed, such as space jumping based on cosmic strings, the problem now is that our position has been moving, which means that we are still in the process of crossing, not at the end of crossing. No one can stay inside the wormhole or jump In the space crack! "

"What the hell is this place?"

"This is ramra!" said Mrs. Larry suddenly, who had not spoken.

"Ramra?"

"Yes," said Mrs. Larry, looking at the savages standing or sitting quietly not far away. "That's what they call."

"That's what my tribe calls it," situ said. "It seems that although their languages are different, they are consistent in some important noun names."

"What's the use of just knowing a noun? I can also give it the name of a 5A scenic spot in the Galaxy! You have to at least give it a definition -" Boris said. "Is it ramra island? Ramra planet? Or ramra boasting club?"

"There's more than one island here, but I'm not sure if it's a planet. They obviously don't have such a concept," Mrs. Larry said

"I can help them perfect the term -" situ said. "Ramlah ant nest!"

"Ant nest?"

Situ nodded: "In our impression, we have been on the island all the time. But from the changes of the starry sky, we can infer that we have been changing the position of space. That is to say, the ramra space we are in is probably not a wormhole connecting two endpoints, but a complex distorted space composed of multiple wormholes or multiple cosmic strings, which connects more than one endpoint, There may be three, five or even countless. Any two endpoints can be interconnected. When the number of endpoints increases, the number of spatial connecting lines, that is, channels, will double. There is only one channel for two endpoints, ten channels for five endpoints and (n-1) for n endpoints N2 channels. These channels all return through a high-dimensional space, just as the bottleneck of Klein bottle returns to the belly of three-dimensional bottle through four-dimensional space.

When discussing the structure of cosmic space, we have made such a model and named this structure as the 'ant nest' structure. The high-dimensional space through which all channels pass is called the mother nest, and the mother nest is usually a black hole. "

"Why is it called an ant nest? It sounds a bit like..." Boris imagined a black hole with many soft and twisted tentacles stretched out. "A black anemone?"

Situ said: "The sea anemone may look more vivid, but it doesn't conform to the definition of space. Have you seen the nest of ants? Ants can be simply defined as approximate two-dimensional creatures. In their world, everything is flat, and the ground has no ups and downs. Therefore, when we explain the plane structure of Mobius belt or Klein bottle, we always like to let an ant climb over. But the nest of ants The structure is very complex. Even in the three-dimensional world, it can be called very exquisite. This is a typical example of a creature building a spatial structure beyond its own dimension. Therefore, we call the complex spatial structure that exists in the dimension of our life and is higher than our dimension 'ant nest'. "

"To put it bluntly, it's still wormhole quack!" the crow muttered.

"Yes, the ant cave is still a wormhole!" situ laughed, "but this wormhole is much more complex and advanced than the usual wormhole."

"Do you still have to go through the black hole?" Su Huilan thought it was unrealistic to go through the black hole.

"A single wormhole must start with a black hole and end with a black hole or a white hole, but the ant cave is not. All channels of the ant cave are connected to the black hole, but they do not necessarily need to pass through the black hole. Remember the Klein bottle you said? When the bottleneck enters the bottle, it passes through a four-dimensional space, but the surface of the bottle can be completely exposed in three-dimensional space, because it has only one plane, The same plane will not be in two different three-dimensional spaces. The same is true of the ant cave. Its channel passes through the black hole or is affected by the gravity of the black hole, but when we shuttle on its three-dimensional wall, we don't need to enter the interior of the black hole. "

"Because it's wriggling?" Su Huilan thought and said.

"Yes, because it's wriggling." situ nodded, "Any kind of wormhole in accordance with general relativity will collapse unless it is supported by strange matter with negative energy. We are now in the ramra ant cave full of strange energy. This is the surfboard we ride. When we approach the black hole, this energy and the repulsion of the black hole will creep space and we will slide away from the edge of the black hole."

"Do you mean that every time there is fog, we are close to the black hole?"

"That's not certain. For example, we go to the island when it's foggy on the earth, but it's obviously impossible for the earth to get close to the black hole. I think it may be that when some energy in this space accumulates to a certain extent, ramra will automatically open the closed state and release these energy, and fogging is just its appearance. Just like when we drive, it's inevitable for people to be in the car for a long time If there is fog, open the window and let the wind pass. "

"Then when it comes to fog, the space crack opens, and we have a chance to go back to earth!"

"Yes, but it's also possible to go further."
