Chapter 3

Opal began to yearn for the boundless expanse of the universe and the starry sky. He began to ask himself, where can I go after leaving here? His mother had come from space. Her ship was dilapidated and rusty. She seemed to be the only passenger on board. She did not know why she gave birth to herself and did not leave B-11 any more.

He left the mine early the next day, and with the star chart, he could not wait to come to the laikett's home.

He pulled over another load of ore, but found no one in the cave.

"Ractor Cried opal.

In the vast wind, ractor stood on the endless stone field, and his robe was flying in the wind.

He just stood there, motionless.

Opal looked away for a moment and found that ractor had been standing in this position for a long time.

After a full hour, Rakuten opened his eyes and turned around.

"What are you doing?" opal asked

"Meditate," Lecter said

Opal: Meditation

Rex: "spread out your mind and spirit and explore the unknown."

Opal nodded vaguely, and the two began to pour the ore into the atomic furnace. Ractor said, "three and a half percent."

"That's the only way to find it. It's not very pure," opal said

"Didn't the foreman embarrass you?" said Lecter

"He didn't care about it, but it was for food. I just told him I needed to purify it myself," opal said

He sat outside the cave with ractor. Opal took the star map to the zenith and asked, "which planet is your home on?"

"The place I came from was an unmarked location on the central axis of the expansion point of the universe, which was formed in the early days of the universe," he said

"I didn't understand," opal said

"Do you know how the stars come from?" rakert asked

Opal: I don't know. Haven't they been there all the time

Rex: "of course not, they first existed 20 billion years ago, when the universe was still a point, there was no time and no space. At one point, it exploded, and time was emitted along the explosion point. Energy was converted into mass in the first few seconds, forming many planets. And the stars were born

"What was that before they were born?" opal said

"There's no time before they're born, and of course it doesn't matter before."

Opal was a little confused, and ractor added: "under normal conditions, time is an axis. When you ask about what happened before, you must look for the direction of the thread and fix the point again. Once you go back to the end of the line, you can't find any more lines. So before the birth of time, if there is no time, it doesn't matter before. "

"Because the starting point of time is defined by human beings, you can think of space-time as a planet like B11. What will happen if you go south all the way? Try to think about it. "

"You will go to the south pole, and the concept of" south "is just like" before ". You keep going forward to the starting point, so you stand at the south pole, and there is no further south. There is no point in asking where South Antarctica is, as it was before the start of time. "

Opal seemed to understand something, but he was more confused. Ractor added, "my place of origin is called the hall of stars. It's on the axis of the original explosion point. The primordial explosion point is a constant point. The star map given to you yesterday uses the coordinates of the center point different from the current universal star map of the universe

Opal was in a mess and asked subconsciously, "what's the difference?"

"Your star map reference point is the location of the temple of stars, which the first star Knight thought was the center of the universe," raikker said. All other civilizations, on the other hand, use another point called "Earth" as a relative reference frame to define the coordinates on the map

"Can the earth move?" opal asked

"Its movement is almost negligible for the motion between the nebulae," rakert said. But occasionally you look for a star in the map of Empires and republics, and you may find that it's not there, because of the earth's revolution, the movement of the solar system, and the rotation of the Milky way

Opal was completely confused. He tried to open another topic and asked, "what do you usually do?"

"To learn, to fight, to eliminate all the instability in the interstellar world," Lecter replied

Opal said, "like cleaning up your enemies? Will you kill him? "

Ractor said, lost in a long thought. Opal asked, "how did you fight?"

Lektre frowned, as if thinking about the method of explanation. After a long time, he said: "kill and destroy are two concepts. He is a star Knight corroded by dark energy. His life is very long and he has mastered some power I don't know. I set out from the temple and looked for him for a long time. At last, he set a trap. We fought near a nebula. Finally, I failed. That's it. These days, I'm reflecting on how to deal with him. "Opal began to imagine the fight between ractor. He had never seen the universe, nor did he know how powerful Rickert was with his opponents. To imagine, he could not escape from the scene of miners' fighting. The only difference was that ractor's Duel became a little larger.

Ractor laughed. He didn't say anything. Opal asked, "how old are you this year?"

"A few thousand years old," raikker said

Opal: "no way! Are you so old? "

"How long can I live?" he asked? I heard them say that human beings are going to die at the age of one hundred. "

"Everyone has a life span, and it's not the length that matters, it's what you do and what you've experienced with your limited life," said raikker. There is a kind of intelligent life on mayfly in the beta Andromeda galaxy, whose life span is only 0.05 seconds

Opal:!! "

Ractor smiles. His smile is handsome and gentle.

Opal: didn't you die as soon as you were born

"Mayfly is a neutron star, and it's as big as a microbe, moving close to the speed of light, thinking very fast, and our one second is equivalent to their two hundred years. Scholars in the ivory tower in the deep universe once tried to communicate with them using a particle wave converter, but failed. "

"Why?" opal said

"Some people think they know some of the ultimate laws of the universe that exist and die, but ephemeropters refuse to make any communication with the intelligent life of extraterrestrial beings," he said. And their speed of life and death is too fast, and their existence is too short, which is very tricky, because you are still talking to one of the ephemeropters in the last second, and it will reproduce for dozens of generations the next. Every second of mayfly has gone through 20 generations

Opal laughed, and suddenly thought of something, and said, "then they have a longer history?"

"Yes, so it has been speculated that the civilization of Ephemeroptera is the most advanced in the universe. It even goes far beyond the civilization level of the whole universe. Let's talk about it for a moment, and in their history, they have developed for thousands of years."

"It's amazing," opal said

"Go back and have a rest. You have too much work to do. You need to have an early rest and come back to me tomorrow," raikker said

Opal nodded and waved goodbye to him.

The next day opal still went to work, and his mind was full of fantastic ideas from the depths of the stars. Perhaps for ractor, his life was very short - just like a mayfly.

What can I do to live longer like him? He couldn't help thinking about it again and again, but he touched on a new question: what can he do if he lived for thousands of years? Do you have to repeatedly mine and sell ore for food every day? It's better to dig for a hundred years than to dig for thousands of years He didn't want to do it for a minute.

He is right. The key lies in what you have done with your limited life and how much you have experienced in this short 100 years.

"Well, you know what." Opal said to his partner Locke, "do you believe someone can live for thousands of years?"

Locke said, "believe it, what can't be done with money? Last time the foreman had a drink, he said that as long as he saved enough money, he would go to the ChiYan galaxy, find a life medical company, and give you gene injection again to modify your physical condition. As long as you have money, you can live forever! "

"How long can you live?" opal frowned

Locke shrugged, "how do I know? It is possible to keep cell division at the same level as when they were young, 200 years, 300 years, 1000 years. "

"How much is it?" opal asked

"It's said that every gene operation costs millions of energy units, and maybe you're dead before you save that amount," Locke said. Save enough money and buy a ticket. "

Opal's thoughts flew back to the ephemeropter's short life span of only 0.05 seconds, until the magnetic drilling machine stopped.

This mine has been unable to extract much crystal stone, the miners are very worried, have taken off their gloves out.

"I'll have some more bread and water." Opal said to Locke, "can you get me some?"

Locke looked at the foreman in the distance and said, "why do you eat so much recently? I heard you found a man in the desert? Where is it from? "

The miners passed by and talked to each other.

"Another round of ore star bidding is about to start."

"Looking at the top, I think it's a bit suspended this year. There are not many mines in B11. You see, it's almost dug, and no one wants to change hands."

"When bidding last year, the entire amateur galaxy was contracted, and the competition here is relatively less fierce."

Opal motioned to Locke to be quiet and said, "he's from the universe. I don't know anything else. He's hurt."

Locke said, "you ask him to come and dig."

Opal said, "no, he won't do it."Locke said, "otherwise? Food and water are expensive. "

Opal said, "I'll trade today's mine. You can change it for me. I don't want Hicks to know."

Locke took another look at the foreman in the distance. Hicks, the foreman, looked gloomy. Obviously, he was in a bad mood because the mining was exhausted.

"He'll find out sooner or later, and he'll take your energy points." Said Locke.

"I'm not afraid of him," opal said

Locke shivered. Opal said, "listen, Locke, help me with this, and I'll repay you."

Locke helpless way: "no, you wait here."

Locke used to get a list, and the foreman was impatient to count the ore, which was paid by opal. He used two carts of mines to exchange for a lot of bread. He had to find a way to solve the food and drinking water of ractor in advance. Otherwise, it would take him a long time to find a new mine.

The long winter is coming, and the merchant ships of the red flame system will land once on B11, and sell them high price materials for cold protection. For the rest of the time, opal would follow the remaining miners to find new mines, and the foreman would go back to another planet for the winter.

"There is no ore today." "I've changed some food, winter is coming," opal explained to lequet on the rock slope

Ractor nodded and said, "well, it's hard for you."

The rotation axis of B11 is tilted at an angle of 23.5 degrees, which results in short days and long nights in winter. The temperature dropped slowly, and opal and ractor sat on the cliff for dinner. These days he could only eat one meal a day, and the rest of his rations were given to ractor.

When Opal looked at him from time to time, he always felt that it was not polite to call him by his first name. On B11, the foreman was called "Lord Hicks", while businessmen from other galaxies were called "Sir". However, they were not necessarily willing to trade with the miners.

"You can call me teacher, if you like. But I believe that we are equal and have no status. "

Opal was stunned and asked, "why do you know what I'm thinking?"

"You're thinking about that?" Rickett said with a smile? I'm just saying casually, what the teacher means is the person who teaches you knowledge. "

"I understand," opal said, "my mother told me."

Rick nodded his head and opal asked, "what do you want to teach me today?"

"What do you want to know?" ractor asked

Besides, what do they do in the imperial Republic

"Those things, you will know one day, the future is not far away." Ractor walked slowly and lay down on the open ground of the cliff.

Opal lay down with him and said, "teacher, how did you get to those planets? Do you know a lot of people? Do they respect you? "

Instead of answering, he pointed to the brightest star in the sky and said, "opal, you know, the stars you see are not what they are."

Opal followed what he expected, and said blankly.

"The fastest speed in the universe is light, and nothing can exceed the speed of light," he said

"I know that, and my mother said, the best ships can't fly faster than light," opal said

According to Archean mass energy theorem, nothing with mass can move faster than light. We're very, very far away from the alpha Andromeda you see, and even the fastest light in the universe will take three million years to get here from alpha. "

Opal:

"Suppose a long time ago, a beam of light came out of alpha star, after three million years, and finally arrived at our planet and entered your eyes, then what you saw was what it looked like three million years ago. Can you understand that?"

Opal nodded slowly, and lequet said, "even if we drive sol, the fastest spaceship in the universe, to travel at the speed of sublight, it will take millions, even tens of millions of years, to travel between galaxies."

Opal said blankly, "so how did you travel?"

"Use the Stargate," he said

"Our world is called four-dimensional space. Three axes establish three-dimensional space, and the fourth dimensional time axis is the universe we are living in."

Opal understood a little and asked, "is the space door a door Well, I mean it's a long way to go in and out of here. "

"It can be understood that 20000 years ago, the ancestors of mankind found the fifth dimension that connects with our space. This is a period of history. You don't need to be very clear, just remember it."

Opal listened quietly, and Lecter explained: "the cause of the event is that a group of scientists found particles faster than the speed of light in particle collision experiments. After hundreds of years of repeated investigation, they found that they met certain conditions and entered the fifth dimensional space instantaneously in the middle of the way, and the five-dimensional space showed very strange properties in space and time.""If you succeed in entering, as long as you advance a short distance in the fifth dimension and return to our four-dimensional world, you will find that you have already gone a long way I'll give you an analogy

Rickert pressed his wrist, and a light from his bracelet fell on the opposite cliff. He casually explained: "the stone wall opposite is a two-dimensional plane, and the light spot is on the left, and we are in a three-dimensional world, higher than the two-dimensional space."

"Well." Opal nodded.

Ractor turned his wrist slightly, and the spot moved hundreds of meters in an instant, and the landing point changed to the end of the cliff on the right.

"The light spot is a projection of a three-dimensional world on a two-dimensional plane. I just need to make a small movement in a higher dimensional space, and in half a second, the angular velocity can make it move hundreds of meters," said raikker. As long as the projection relationship is successfully established, two centimeters in three dimensions can be directly equal to 200 meters in the two-dimensional plane. "

"In the same way, after forming a projection connection in the five-dimensional space to the four-dimensional space, you have traveled a kilometer in the five-dimensional space, which is equivalent to several light-years' journey in the four-dimensional space. This is the membrane principle of multi-dimensional projective angular velocity. "

"I see," opal said immediately

"To explore our universe, we must rely on higher dimensional space. The principle of stargate is to let you enter the fifth dimension briefly, and open a tunnel in this dimension. After a short journey, you and your spaceship can cross millions, even thousands Ten thousand light years away. "

"This theory was put into practice in ancient human civilization. The day when the first pair of star gates were successfully opened to navigation was the beginning of the light era. The ancestors of mankind have developed the leap ship and started to explore the whole universe and establish the original Stargate. More and more people left the earth to colonize the interstellar space and spread their branches and leaves. Now it is the year of the light era of 20103. After 20000 years of evolution, human technology has become what we see today. "

Opal's eyes were full of wonder.

Neither of them spoke. After a long time, opal asked again, "if I want to travel in space, do I have to go through the Stargate? Where is it? "

"There are tens of thousands of ChiYan galaxies." "Spaceships are equipped with locators, which form a crisscross network of galaxies that you can find anytime, anywhere, as long as you go into space," raikker said. In fact, there is one at 7.5 light minutes away from here, but few people use it. Most people don't even know the existence of this channel. "

"You don't need specific procedures to get in and out of the gate, but if you land on a civilized planet, you need a specific pass to pass through the outer atmospheric space station. Without a pass, you can't walk through the universe."

Opal sighed softly and closed his eyes. The wind at night became cool. After a while, he fell asleep unconsciously.

Today, instead of letting him go back, ractor picked him up and put him in his cave. The atomic furnace glowed warm orange.
