Chapter 1419

"Grandfather, when does it take for humans to break through the Kuiper belt?"

In the face of his granddaughter's question, Lu Chuan felt a sense of embarrassment. The other party is really her granddaughter, but she is over 80 years old. It is not too much to say that she is an old granny because she has not been strengthened.

The other side said his name was grandfather. If the outside world heard it, I'm afraid it would lead to criticism.

Lu Chuan still replied: "it may take three levels of civilization before human beings have enough scientific and technological strength to break through this Kuiper belt, but they can't come and go freely. Only after the fourth level of civilization can we travel normally. "

After the third level civilization, the existence of the energy shield allows special spacecraft to fly over here, but it is definitely not free sailing.

The numerous planets and meteorites that have collided with each other need several elements. The first is that the speed of sailing is fast enough to dodge quickly. Second, we need a spacecraft that is flexible enough to give way in milliseconds. Third, it has strong energy, which supports the consumption of energy shield when it is impacted. Fourth, it has a super strong attack power that can destroy the Impact spacecraft planets when necessary.

If the four conditions are met, we can basically go through.

After the fourth level civilization, a new energy shield system will come out, so that after ignoring the impact of some planets and meteorites, it is time to travel freely. Compared with the destruction of ships and the destruction of human beings, spaceships of level 4 civilization can take these impacts as itching.

Ye Lingwei can't imagine what the third level civilization is like, beyond their understanding.

Lu Chuan is also more knowledgeable, just familiar with all levels of civilization.

"Now, I'll take you through, in a physical way." Lu Chuan said with a smile that if you want to go through, you can do it with one idea, but it's meaningless. Lu Chuan needs to let them experience more magical places in the universe and exercise their super strong heart.

Ye Lingwei and they are all ready, knowing that there will be no danger, but they are still nervous.

As soon as Lu Chuan's arm shook, the cosmic energy suddenly appeared. In Lu Chuan's mind, it was like an invisible arm, and Qiangsheng separated a huge crack in the Kuiper belt. Countless planets and meteorites, repelled by energy, are separated from each other.

This transparent bubble, with people, is moving forward with an unprecedented thing.

"The width of the Kuiper belt, at the speed we're flying at, and the obstacles it's hitting, could take 20 to 30, 000 years to cross." Lu Chuan explained a sentence, let Ye Lingwei, they are all heart and mind a shock.

What is the concept of 20000-30000 years?

For the first time, ye Lingwei and their extremely clear understanding of the terrible universe.

Innumerable planets and meteorites whistling past on the edge of the bubble. What kind of speed will pass in an instant? God knows what kind of consequences will be brought under the impact?

Lu Chuan, with his family, is walking fast here.

Occasionally, Lu Chuan plays with his heart, and controls the bubbles. He walks through here, avoiding the roaring meteorites. It's like walking a steel wire rope. His heart beating makes people scream and scream.

Compared with what kind of roller coaster, this is really exciting.

However, Lu Chuan did not play for long. In his mind, Lu Chuan had already disappeared in the Kuiper belt with them. When he appeared, he was already outside the Kuiper belt.

"Humans have always believed that when they cross the Kuiper belt, they will leave the solar system and enter the Milky way. There is no mistake in understanding, but it is wrong in fact, because human beings are just like being imprisoned by God, and it is hard to escape forever. "

Lu Chuan's voice sounded low, because after leaving the Kuiper belt, it was not the endless starry sky in human imagination, but The endless white Oort cloud.

When it comes to altcloud, many people have no idea what it is.

In fact, beyond the Kuiper belt, there is a much more terrifying and vast area that human beings may never cross. This is the Oort cloud.

The Oort cloud is composed of trillions of spherical celestial bodies composed of ice bodies. It covers the whole solar system in an omni-directional and three-dimensional way, which means that in the universe, no matter what direction you fly, you will eventually have to face it.

Whether or not to leave the solar system, there is a criterion that the celestial body is no longer affected by the sun's gravity.

The movement of small celestial bodies in the Oort cloud has been proved to be driven by the sun's gravity. In other words, it is the largest outer shell of the solar system, a kind of celestial body protection zone composed of ice bodies.

From Kuiper to Altair, take the once famous Voyager II in North America as an example. It takes 300 years to reach the cloud and 30000 years to cross it.

Hearing Lu Chuan's talk about this knowledge of the universe, ye Lingwei felt that their thinking could not be used.

"After the solar system, there is the Milky way, not to mention all kinds of dangers. The nearest galaxy outside the Milky way is also measured in millions of light-years. In this blank space, there is no complete vacuum in any celestial body. In these vacuum zones, there is no light, nothing It's more like a land of nothingness. "The characteristic of the Oort cloud is that there are endless ice bodies, so the temperature here is so low that you can't tell.

"Next, I'll take you to the central galaxy of the Milky way, where humans have always believed in extraterrestrial life." Lu Chuan laughed. If he didn't move his mind, he would never have been able to reach these places.

One idea, Lu Chuan and ye Lingwei disappear.

When it appeared, Luchuan appeared on the surface of a huge and incomparable desolate planet. This was the place where Luchuan had been. There was a mark of Luchuan here, and he could arrive here in an instant.

Standing here, you can see a large number of all kinds of celestial bodies, they are so close, as if there are some fluctuations, will produce a huge collision.

And in these huge celestial bodies, you can see countless starlight spots.

But all of this is a false image. In the center, there are two super neutron stars. They emit 200000 times more light than the sun, and they emit gamma rays all the time, producing a gamma ray storm and sweeping here.

"This is the central galaxy of the Milky way. It is in the eye of rotation, so this is the almost static existence in the whole galaxy. The celestial bodies here do not rotate or move, so they are so close that there is no need to worry about collisions."

"But there will be no life here, even the forbidden zone of life. Have you seen the two celestial bodies that are too bright to be opened? The light they release is not suitable for the birth of life

Lu Chuan simply explained that after they were used to the environment here, they disappeared again with them.

…………

The Andromeda galaxy.

It's so far away from human beings that it's beyond the scope of calculation.

Lu Chuan has been here several times and naturally knows that there are alien races here. At this station, Lu Chuan decided to take ye Lingwei to see more shocking alien races and civilizations.

"They don't see us, and they don't know we're looking at them."

Lu Chuan gives Ye Lingwei a reassurance. After all, she suddenly arrived here from the center of the galaxy. In the face of a civilization combining technology and magic, no one can immediately accept all this.

It's a demigod race with superb technology and fantastic magic power.

For example, their life form is actually the form of energy from the very beginning. They created a technological civilization, created a robot similar to human beings, and then put themselves into the robot's brain.

They are the brain. The brain is them.

For all kinds of robots, their heads are shining with a flash of energy, showing a bright green color. Different body structures mean what work they need to do.

If you want to change the work, you just need to change the robot. As long as they drill into the head of the robot, they can activate these robots and work flexibly.

In the universe, it is indeed all inclusive, and the existence of life civilization is also beyond imagination.

"I call them brain people because they are born with a brain." Lu Chuan laughed and named his family. It is absolutely necessary to travel around the universe.

Don't underestimate the brain race. Their civilization has surpassed that of human beings. It should have reached the level of 2.5 civilization. They don't have Dyson balls, but they are much more energy efficient than tertiary civilizations.

Brain civilization, its technological path and human is the most similar, which is why Lu Chuan brought Ye Lingwei here, at least did not scare them.

Like a spectator, people have been watching all this with great interest, with human eyes, like watching the animals in the zoo.

It seems that there is nothing excessive about this proportion. They do this kind of thing now.

Just above their heads, they observe their every move like a God, and they don't notice at all. This kind of behavior, like peeping, can always bring some kind of satisfying sensory stimulation.

Lu Chuan held his arms and did not disturb them, but from time to time he appeared in cities with them.

When they were all tired of aesthetic appreciation, Lu Chuan said, "you should be hungry and tired, just take this opportunity to get news. This time I'm going to a place that is beyond your imagination. It's also the new residence I've chosen for you. "

"Where is it?" Shi Ruoyu has the fastest response. She is definitely a food eater. As you can see from the food city she has made on Mars, she has opened a shop in the food city by various means.

Driven by madness, the food city in Mars has always been the Holy Land in the eyes of food.

Lu Chuan said with a smile: "you will know immediately."

Seeing Lu Chuan's betrayal and ye Lingwei, they were all intrigued and looked forward to.

"Ready, close your eyes first, and then open them when I say you can open them." Lu Chuan snapped his fingers. All of them closed their eyes. They seemed to feel the movement, and then they were still.They know that they must have arrived at their destination.

"Now you can open your eyes."

Lu Chuan laughs. There is no need to protect them here. They can breathe the air freely, and they will not be in any danger here.
