Chapter 1419 (1/2)

”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.
