Elon Musk is a space worker. When Yang Xiaotian said that, Elon Musk was deeply touched.

In space, the human's steps are indeed shrinking, just like the tortoise crawling.

"But there is no way to do this. Capital needs to increase in value, but activities like landing on the moon have nothing to do but dig some potential stones." Elon Musk regretfully said, "compared with the remote space, people prefer to put money into human social life. NASA's current resources are barely enough to maintain its own technology

"Everything is too slow for us." Yang Xiaotian said, "in the 1960s, the power of nuclear fusion was mastered by us. But up to now, controllable nuclear fusion technology has not been realized. "

Elon Musk said: "we can produce fusion at a temperature of 100 million degrees, but we are just short of the furnace that can restrain the temperature of 100 million degrees. Now that plasma confinement high temperature is becoming more and more mature, I believe that controllable nuclear fusion technology will be realized in 50 years. "

Yang Xiaotian said: "fifty years, too long, or too slow."

Elon Musk

"In fact, it is extremely difficult to promote controllable nuclear fusion even if it is invented now. A lot of people, they will be obstacles. " Yang Xiaotian said, "because controllable nuclear fusion technology will make oil lose its maximum value, and oil is closely related to us dollar hegemony. In order to maintain US dollar hegemony, controllable nuclear fusion technology is bound to be unable to be applied on a large scale."

This time, not only Elon Musk was stunned. Everyone was stunned. They know that Yang Xiaotian has no taboos, but they didn't expect that Yang Xiaotian's courage is so big that he told the truth.

But Yang Xiaotian, no matter whether everyone was surprised or not, continued: "my artificial intelligence is the same. I can use artificial intelligence to replace human labor, liberate human from heavy labor, and realize the great development of productivity. But I am hindered, and I can't do that. If you do that, everyone will lose their jobs. "

Elon Musk said with a wry smile: "everything has advantages and disadvantages. Sometimes, it is either advanced or widely used. Tesla has been using alternating current for a long time, but people have been using Edison's direct current. All advanced things need time to be based on the world. "

"So I said we were too slow!" Yang Xiaotian said, "do you know the civilization level of the universe?"

"I seem to have heard of it." "But I didn't remember it," Elon Musk said

Facing the curious people, Yang Xiaotian said solemnly: "I watch the sky at night, think deeply, and sum up the universe civilization into seven levels."

"I'd like to hear it in detail," Elon Musk said

"The first level civilization is a civilization that can use all the resources on its own planet. This level civilization can develop its own planet to the extreme." Yang Xiaotian said.

"So we humans can't even reach the first level of civilization?" Elon Musk road.

"We should be 0.7 civilization, or lower." Yang Xiaotian said.

"That sounds terrible..." said Elon Musk.

"The second level civilization can make use of the energy of the star system in which it is located, and the most typical one is to build a Dyson sphere." Yang xiaotiandao.

The Dyson sphere is a kind of energy collection device around the sun, which aims to intercept all the energy of the star, and then use it. Stars have more energy than nuclear fusion.

"I'm afraid that all the materials in the solar system, except the sun, are not enough to make a real sense of Dyson sphere." Elon Musk road. On the one hand, Elon Musk said, why is the topic getting more and more strange? Is Yang Xiaotian just borrowing a topic? Does Yang Xiaotian have any deep meaning?

"The third level civilization is God level civilization for us. The third level civilization can easily master the galaxy. If we humans can master the whole galaxy, then it is the third level civilization. " Yang Xiaotian said.

This is Yang Xiaotian's own division. In today's Yang Xiaotian's view, the light tower civilization is the third level civilization, and the silicon-based empire is the 1.5 level civilization. However, the third level civilization, for human beings, is already an incredible God level civilization.

Elon Musk is completely speechless. He can't understand what Yang Xiaotian means when he says these things. And his expression was like this: · · ·

"The third level civilization is already so powerful, and the fourth level civilization is even more incredible." Yang Xiaotian's eyes look at the sky, his eyes are very deep, as if through infinite space and time, "civilization reaching level 4 is already a cosmic civilization. Civilization reaching this level can develop 70% - 80% of the energy of the whole universe, can sense and detect the cosmic coordinates of all galaxies, and can communicate with other galactic civilizations in some way."

"Is the topic a little far away?" Elon Musk had to remind Yang Xiaotian, "what you said is more and more mysterious."

"Don't worry, finish first." Yang Xiaotian took a sip of tea, moistened his throat and continued, "as for the five level civilization... The five level civilization is called multidimensional space transformation civilization. The five level civilization grasps the mystery of dimension, and can cross it at will.

For example, this civilization can transform the earth in three dimensions into four or even higher dimensions.

In this way, we can go back to the past of the earth, and also lead to the future of the earth, so we can freely carry out activities in multi-dimensional space.

This level of civilization has gone beyond time, and crossing is their necessary skill. "

Since Yang Xiaotian doesn't want to end the current strange topic, Elon Musk can't stop Yang Xiaotian. He can only follow Yang Xiaotian's meaning and say: "it's an unimaginable civilization. If a civilization reaches this level, it's not God to us? This reminds me of the famous movie "Star Trek", which opens a wormhole for human beings and leads men into the four-dimensional space. It should be what you call the five level civilization

"Maybe!" Yang Xiaotian said, "do you know the parallel universe hypothesis?"

Elon Musk said, "the hypothesis extended from Schrodinger's cat?"

Yang Xiaotian said with a smile: "it's also a favorite setting of some creators. As the saying goes, it doesn't explain. Parallel time and space."

Elon Musk also laughed: "yes, there are so many parallel spacetimes in the Marvel Universe. It's so chaotic that even senior Marvel fans can't make it clear."

Because he is the archetype of iron man, Elon Musk has seen Marvel's movies and comics.
