"Then we earthlings and you Atlanteans are long-lost brothers?"

"Although our early ancestors were born in the same comet belt, after the Creator dispersed us into different galaxies, we humans also diverged and changed our structure slightly. Pen, fun, pavilion www. biquge。 For example, we Atlantis are a civilization of light, we are sensitive to light, rely on light to survive and obtain energy, and our last civilization, Daya civilization, they evolved a third eye and have superpowers, and you are now earthlings, how do you know for yourself. ”

"Oh, is that how the earth was meant to be? Why did everyone come to the earth? ”

"We don't know what the purpose of the designer was to design and mass-produce early humans, and then disperse them to various galaxies and give them the ability to reproduce themselves, but it probably just wanted us intelligent people to quickly spread to all corners of the universe. And then why this is happening, then it is unknown, just like the spread of the virus. The earth is such a planet that has been freely spread by us humans. Because the geographical location of the earth is still relatively suitable for human reproduction. ”

"Was that what the earth was like in the first place?"

"Of course not, the early Earth was small, much smaller than it is now, and there were no oceans, just a hard shell. After being irradiated by the sun for many billions of years, the inner core of the earth gradually absorbs energy, and many chemical and physical reactions occur, which can also be called hot core reactions, so water is gradually produced. And the amount of water is so large that it explodes the hard shell of the earth, so the earth is divided into many continents, which are just eggshells that have been squeezed. So it's not the so-called continental drift theory, it's just fragments that have been crushed by liquids, so now there are land and oceans on the earth. Because the earth is not dead, it is like a seed that slowly grows under the nurturing of the sun and becomes what it is now. And as the Earth continues to absorb energy from the sun, it will continue to grow. ”

"My worldview has really been refreshed today, and the system has been updated. Besides, are we going to go to the playground now? ”

Mina led me to something strange that looked like a mirror, took my hand and said, "I'll take you in through the passage of light." ”

I looked at the mirror in front of me and wondered, "Isn't this just a mirror? ”

Mina: "Do you see you in the mirror now? But when you looked in the mirror before, did you think that the person in the mirror is also real? ”

I was stunned, and I shuddered in my heart, could it be that we look in the mirror every day and see ourselves in the mirror, which also exists in a certain time and space.

Mina pulled me into the mirror.

I hadn't come back to my senses, but when I opened my eyes, I found myself in the playground.

Mina: "With your current knowledge, I can't explain so many principles to you, but I guess if you can go into the mirror, you can walk through the gap between time and space. This is the channel of light. Well, without further ado, let's have fun. ”

I finally came to this playground, and I was so happy to find that there were quite a lot of amusement facilities in it, but there were not many people, only a few. Maybe the population of this island is not large.

"I want to ride that roller coaster!" I excitedly pointed to the roller coaster in front of me, "can you ride with me once?" ”

Mina: "Okay, let's go. ”

I happily ran to the entrance of the roller coaster.

Although I have been in Shanghai for so many years, I have never been on a roller coaster. One is that I am a little scared in my heart, and the other is that I hope that when I am scared on the roller coaster, there will be someone next to me so that I am no longer afraid. But there has never been such a person. But today, finally, it can.

Although Shanghai is a lonely city, it is not so lonely if there is such an island next to it. Hopefully the island will always be there, and Mina will always be there.

There are very few people in the roller coaster project, just a father and son in front of us and the two of us.

Mina and I took a seat and sat down and fastened our seatbelts.

With gentle voice prompts, the roller coaster began to accelerate, faster and faster, and I was so scared that I closed my eyes and grabbed Mina's hand tightly.

After a while, the speed began to steady, and Mina patted me: "It's time to open your eyes." ”

I opened my eyes and was shocked to find that the roller coaster was actually driving under the sea.

I asked curiously, "What's going on." ”

Mina: "This roller coaster is not the same as your inland roller coaster, ours is in the river of photons I told you earlier, so it can be much faster than the speed of light. Not just the bottom of the sea, but also further afield. And this roller coaster we built is actually a science and education ride, just like your science and technology museum, taking our children to sail around the universe and learn about the universe and history. If you look at the outside now, it's a city built by us Atlanteans on the bottom of the sea, and most of us Atlantis now live under the sea, and the bottom of the sea is much bigger than the little land out there. ”

I wiped my eyes, and sure enough, I saw a city under the sea, with tall buildings, roads, and cars under the sea.

"It's beautiful," I couldn't help but admire.

Mina continued, "And our last civilization, the Mesopotian civilization, lived in the heart of the earth, and that was their territory. Because we didn't have an agreement with them, our roller coaster can't go to the center of the earth right now. But I can describe to you what it was like there: because as the earth expands more and more as it orbits the sun, the interior is already hollow according to the centrifugal force, just like the hand-rotated pottery made by you inlandmen. The last civilization, the Mesopotamian civilization, had turned to the inner part of the earth in order to escape the nuclear war that had taken place on the surface of the earth. In fact, the environment inside is similar to that of the earth, there are animals and plants, but the creatures living in the center of the earth rely on centrifugal force to cling to the inner wall of the earth. And if you accidentally run to the center of the earth, because the combined force of all sides is 0 in the center of the earth, and it is basically weightless, and you don't have any force points, you may be trapped there forever and can't get out. Okay, you're seated, the roller coaster is going to speed up again, and it's time to get to the next stop. ”

With a burst of accelerated vertigo, I felt the roller coaster speed up again, and I was so frightened that I closed my eyes and grabbed Mina's hand.

The roller coaster has slowed down again. I opened my eyes and went to the next stop.

"Where is this?" I looked up, and there was a starry sky, presumably outside the earth.

"This is already the edge of the solar system, and there is a comet belt here. Comets are actually equivalent to couriers of the universe, they can travel back and forth between planets, and bring some products of different planets or moons are comets, they are not as fleeting as meteors, nor are they as standstill as planets, they can travel long distances and shuttle around the universe. So sometimes we have to send things to other places, often through comet teleportation, saving a lot of money. It is said that when the Creator created our early humans, he also teleported humans to various parts of the universe through comets. So comets are really messengers of life. ”

I look at the solar system from the edge of the solar system, like a warm eggshell, faintly glowing against a dark background.

I wondered, why is there light in the bright star system, why is the universe still dark, why can't the light fill the universe? Is it just because of the obscuration of dark matter?

Mina reminded me again, "Sit down, our next stop is the farthest this roller coaster can reach: the center of the universe."

"The center of the universe!?" I was taken aback, "Isn't the universe boundless, and if it's boundless, where does the center come from? Are you kidding me?"

"It's true that the universe is boundless," Mina patiently explained, "but it's only boundless in space, but in the time axis, the universe is finite, not just finite, it's a sphere, it has an axis of rotation. In fact, there is a man named Hawking who has already explained this thing. Just like if you are standing on the earth now, you can also say that the earth is boundless, because you can go in any direction, and you will not be able to reach the end, as long as you don't jump out, the earth is infinite. So the universe is actually the same, you start from a certain point in the universe to a constant direction, and after a few years of going around the universe, you will naturally return to the same place. So if we want to go to the center of the universe this time, we will naturally travel along the timeline and go back to the place where the universe was first formed, which is the geometric center of the universe. ”

"Are you kidding, if we go back to the beginning of the universe, then we will all hang up, because we were not born at that time. ”

"Don't worry, we don't go back by ourselves, we just freeze the universe for a moment, we go back in time, and come back after reading it. Just like when you watch a videotape, if you want to see the plot at the beginning, you just press the pause button, then rewind backwards, rewind to the beginning of the picture, look at it and go forward, and go back to the place where you paused it. This process takes zero time because the timeline is still at the same point. ”

"I can only look at it. ”

"Of course, we can only see, if we spend more than a second there, the entire roller coaster will be blown up by the initial heat and pressure of the universe, and we will not be able to come back. ”

"So, can time go back to the beginning of the universe, and it can go back to any time in the past? ”

"Absolutely, but this roller coaster doesn't have those stops. ”

"Then if I go back to the Tang Dynasty and enter the time and space at that time, will it be possible to change history?"

"Of course not, history can't be changed. Just look at it. ”

The roller coaster began to accelerate again. According to Mina, natural time also travels at the speed of light, and when accelerated parallel to the time axis, one can enter a rift in time, so that one can swim in the time axis.

The roller coaster started to slow down, and when I opened my eyes, I saw a very strange sight.

"Is this the universe in its initial state?"

"That's right, the universe in its initial state is very small and hasn't grown yet. ”

And I saw that although the universe was small at this time, it did not have only photons and hydrogen atoms as said in popular science books, and nothing else, but already had the prototype of the Milky Way and other galaxies that were still in their infancy.

Moreover, at this time, the light is propagating in a curve, moving in a circle around the universe. In fact, even the current photons are curved and propagated, but the curvature is relatively small. This curvature is also the curvature of the bending of the universe.

It's hard to imagine what it's like to compress so much matter in such a confined space.

"Actually, the universe at this time is equivalent to a black hole?" I began to think again.

"That's right. Mina said, "In fact, every black hole in the universe has a good chance of creating another universe." The universe, like living beings, will also reproduce, one life two, two to three, and give birth to new universes. ”

"That is, if you enter a black hole, you may enter another new civilization?"

"It's possible. ”

Once again, I refreshed my worldview.

At this point, the stop time is up, and the roller coaster is accelerating again and is about to return.

After a period of darkness, the roller coaster is back in place.

This playground is so fun. Mina and I played through the various projects in the playground.

Then Mina took me out of the playground and went with me around town.

Although there are not many people in this town, the layout is still very similar to the domestic town, the same style of architecture, and the feeling of a very comfortable Jiangnan town.

While shopping with Mina, I asked, "Why is it that there is such a small island on the edge of Shanghai for so many years, but people on the earth have no idea about it?" There is no information about this island on the map, as if it is completely invisible. ”

Mina: "Don't forget that we in Atlantis are a civilization of light, and it is not difficult for us to make a small island invisible to the outside world. Everything related to light is our strength. Where there is light, there is the power of our Atlantis. ”

I asked Mina, "Aren't you Atlanteans already living under the sea, and how did this island come about?"

Mina talked about the history of Atlantis: "Many, many years ago, in order to escape the climate catastrophe at that time, we Atlanteans moved to the bottom of the sea to live, and the continent of Atlantis also sank into the Atlantic Ocean, and we gradually adapted to the environment under the sea. But after all, the mainland is our homeland, although there are new immigrants on the mainland at this time. So we in Atlantis have also set up some special administrative regions in many coastal places in the world, and cut off some small islands from the continent to let some Atlanteans live on them. The island you are on now is the one that was intercepted from Shanghai. In this way, we can not only observe the movement of your human civilization in real time, but also make our island a link between your inland humans and our undersea humans. So you see a lot of things on the island that have the shadow of your human society, there's convenience stores, there's parks, there's playgrounds, there's buses, and there's snacks coming in from your interior. Because the people of our island occasionally come to your inland to buy some things and come back to make supplies. But this must be strictly managed, and we must not stay inland for too long, let alone bring in inland humans. Because we don't want to ruin this relationship right now. If you humans find out about us, then our lives will no longer be peaceful, and it may even lead to war. This is the pain in the hearts of our Atlanteans. The reason why we hid at the bottom of the sea is because the nuclear war that broke out between us and another civilization many thousands of years ago destroyed the inland environment of the earth at that time, causing a climate catastrophe, and the atmosphere was full of radiation and harmful gases, so we sank an entire continent to the bottom of the sea to escape this catastrophe. After all these years, you are new immigrants and have only just begun to adapt to everything on Earth. In order to avoid a repetition of history, we will not have much contact with your civilization. ”

"You say that the humans on our continent are immigrants from the constellation Lyra, so why don't we know? ”

"Of course there is, but the culture of your current civilization and the dynasties when you first came back are too long, and only some things at that time have been handed down in the form of murals and ancient texts, and you regard these as ancient myths and legends. After all, there is not much detailed information left in the interior. In the tens of thousands of years since your civilization arrived on Earth, many things and changes have taken place to become what it is now, and you will not understand it now. However, we have some relevant documents and materials in the Imperial Museum, and if you have enough time, I can take you to see it next time. It's still easy to get to and from the Imperial headquarters on our small island. But when it comes to the Earth continent, we have to be much stricter and more cautious. ”

"And how did I get to this island?"

"The only link between our island and the interior is the sea route. Every ten years, this sea route is opened, so that people on our island can go out inland and buy something and come back. Then, at sunset in the evening, the sea route will be opened again to allow the people who have gone out to return to the island. Those of us who go out to buy must wait on time for the opening of the road to the sea, and if we miss it, we will have to wait another ten years. I'm guessing you must have come in from this sea road. ”

I said, "That's right, don't you open your sea road twice every ten years, once to go out and once to come back?" So when I came in, did I let the islanders out of the island, or did I let them come back?"

Mina: "That's when I went out." Because the time you went out was only opened this morning when the sun rose, and this sea road is a two-way street, it's no wonder you didn't meet anyone from the island when you came in from the sea road. And the return of the sea road began at sunset this evening. If you don't make it back by sunset today, you'll have to wait another ten years on this island. You, do you want to go out, or stay here? ”

Immediately I was confused. Although I quite like the comfortable life on this island, there are still a lot of worries for me inland. My loved ones, my job, the hut I rented in Shanghai, and I still have my guitar, the comic sketches I haven't finished drawing, and the songbook of the songs I write. If I don't go back tonight, what will happen to everything in the hinterland? I have disappeared from human society out of thin air for ten years, and that will still have a great impact on the people and things I care about. If I had gone back in 10 years, I would have thrown away the stuff in my rental house, and what I had written for years would have been burned. I'm sure I'm going to lose my job. Although our boss always assigned me a lot of work to do, I still miss him a little at the moment, and I miss his mustache that rises and twists the corners of his mouth.

Mina: "You can now choose to stay or leave. Can you compare that to whether you are happy living in inland Shanghai or on this island?"

In the past few years in Shanghai, I have lived in a drowsy, bumpy and displaced, no object, difficult work, and a lonely struggle alone in this lonely city. Very tired and exhausted. Am I really going to just go back and continue my lonely and miserable life?

Mina: "If you stay here, I'll marry you, and we'll live here together." Ten years from now, when the sea road opens again, we will be able to visit relatives in the interior, and we will not be completely unconnected with the interior. You can also visit relatives and friends in the hinterland. By that time, our children should all be older. ”

Listening to her description, I have a beautiful vision for the future. Can I really go down without being alone? Can I have a permanent home?

I grabbed Mina's hand with both hands, looked her in the eye, and said to her, "Why don't you come with me, follow me inland, we will live there, I will earn money to support my family, I can support you." We can live incognito and live an idyllic life there. ”

Mina said gloomily: "No, I can't live in the interior, and our Atlantean headquarters will not be allowed to stay in the inland human society." After all, we have too many secrets, we want to maintain the status quo, we are afraid that the meeting of two civilizations will lead to war, and we do not want the tragedy of tens of thousands of years ago to be repeated. I can't let two civilizations fall into ruin for the sake of my own children's affection. Tens of thousands of years ago, because of the war between two civilizations, we Atlanteans were forced to dive to the bottom of the sea to live, and we don't want the earth to be destroyed again. It's up to you whether to go or stay. ”

Looking at this beautiful and warm island, as well as the beautiful Mina, this paradise-like life can keep me away from the indifference of the city, away from the loneliness under the street lamp, how I want to live happily here! But looking at the mainland in front of me, Shanghai is on the other side, and there are too many worries for me. Although my life there was not happy, I couldn't really get me out of it.

Mina looked at the sun that was about to set, and said, "The time for the final opening of the Sea Road today is almost up, are you going to stay? The next opening time will be ten years away." ”

Ten years, what is ten years, ten years can happen a lot, it can change a country, it can also make a couple of lovers break up. No wonder Eason Chan wants to sing the song "Ten Years", ten years ago, ten years later, I don't know you, you don't know me, and lovers will become friends.

I sighed and said goodbye to Mina, "I'd better go back." I'm happy here, I'm sad there, but I can't let it go right now. Goodbye, if we still have the fate to meet again. Although I have lost my happiness on this island, I know that I have had a chance to be happy here, and I am satisfied. ”

I turned around and walked towards the place where the sea road was. That's also the direction of the setting sun. When the rays of the setting sun are parallel to the sea level, the sea path begins.

I made it back to land from the sea road without a hitch.

After that, whenever I was lonely, I would look at the sea to the east. Because I know that there is an island there, and every person on the island is something that I dream of.

Shanghai, there really is an island. It's like you're really in love with someone.

Hopefully, there really is such a small island, a small island that belongs to you, when you are sad, you can hide there, you can cry with confidence.

Ten years from now, I will definitely come to this beach on time and wait for the opening of the sea road. At that time, I should have arranged everything. Mina, wait for me.
