"Old sir, please don't be anxious, the kid has just begun, this astronomy is vast and profound, a small solar system, in the grand universe, not even a speck of dust, even in the galaxy, the sun is only one of hundreds of millions of ordinary members. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 info "Li Yi is unforgiving, and he wants to say it all in one breath, and completely conquer Cai Yong, a pretentious old pedant, in terms of momentum.

"The Milky Way? The sun is just an ordinary member of the trillion? "The solar system has not yet been digested and absorbed, and Li Yi threw out a galaxy again, which is really unheard of, which makes Cai Yong feel like he is falling into a fog for five miles, and he feels like he doesn't know what to do.

"The Milky Way is very simple, on a moonless night, the bright white belt across the starry sky is our Milky Way. Visible to the naked eye, it is a white ribbon, and the actual Milky Way is oval-shaped, resembling a whirlpool in a torrent. ”

"What? Wen Yuan is also obsessed with astronomy? Seeing that Li Yi was hesitant and couldn't justify himself, Zhang Ying skillfully solved the problem, and his attention finally shifted.

"It's not obsessive, just pay attention to it!" Zhang Ying's words are flat, which makes people feel like they are not traced.

Off topic, let's continue to discuss astronomy, as for other content, there will be time and opportunities in the future. Li Yi thought to himself, he showed a smile, and continued his topic: "The sun only occupies one trillionth of the Milky Way, which sounds like the Milky Way is big enough, but it is just a speck of dust in the vast universe, but our universe is composed of trillions of celestial bodies similar to the size of the Milky Way. This unimaginably large space entity is the universe in which we live. ”

Cai Yong was really shocked, he didn't say a word anymore, his eyes looked straight ahead, as if he was thinking about something, and as if he was confused. It's no wonder that Cai Yong, a figure who is only in the era of Hun Tianshuo, suddenly received such a huge amount of information, if the brain is not right, then it is strange? Even if he was a genius in astronomy, it would be impossible for him to digest and absorb it in such a short period of time.

Not only Cai Yong fell silent, Zhang Ying also was silent, she had searched for knowledge about astronomy, which was all to cultivate the relationship with Li Yi and increase the common language between the two. Zhang Ying was not interested in this abstract universe, so naturally she did not dabble deeply, and when Li Yi brought it up again after many years, it couldn't help but trigger her recollection.

"I'm talking about these rambling things again, can you change the subject?" Seeing that everyone fell into silence, Yu Bing, who was at a loss, expressed his dissatisfaction.

"Where's Yan'er?" Li Yi's mood was very calm, he had already caught a glimpse of Yu Bing who was listening quietly, but he didn't find Cai Yan, and he couldn't help but feel a little uneasy in his heart.

After playing with Yan'er for a while, she felt hungry, so she went to the neighbor's house to look for her mother. Yu Bing's expression was peaceful. In this mountain village, it is common for children to run from east to west, as long as they do not leave the village, there is no danger.

Li Yi also experienced childhood, his parents worked in the fields, how could he have the energy to take care of him, he could play unscrupulously, thinking about his own experience, his heart was relieved.

But when he heard the change of topic, Li Yi shook his head. You don't discuss what you're good at, once you fall into Cai Lao's rhythm, you will be stripped naked, can you still succeed if you want to recruit him? And the great Confucianism will be full of mouths, and it is simply a sin to think that it is tasteless.

Of course, he couldn't listen to Bing's bad idea, Li Yi ignored it, he still went his own way and continued to explore the mysteries of his universe: "The universe is infinitely mysterious, but it also has laws to follow. Do you two know that the ingredients that make up the universe? ”

Of course, the two of them are Yu Bing and Zhang Ying, as for Cai Yong, who was completely stunned, his brain was not enough, and he had already been on the sidelines, thinking about it for a long time, not knowing what link he was stuck in. Suddenly receiving such a wide range of information, he really couldn't comprehend it in a short time. For Cai Yong, who was meditating on the side, Li Yi adopted a laissez-faire attitude and let him think about himself.

Although this question is complicated and mysterious, it is still difficult for Zhang Ying. As we all know, the universe is made up of about 30% matter and 70% energy. This less than half of the matter is about 20% of the light matter, and more than 80% of the dark matter. This material can be seen and seen, such as planets and stars. Dark matter is more magical, of course, it can't be seen or touched by ordinary methods, and it can only be sensed by using more mysterious methods. However, this dark matter is still not the most mysterious, if you want to talk about the magic, it must be dark energy. Zhang Ying looked a little proud when she talked about this, but it took a lot of effort for her to remember so many marginal knowledge points.

Seeing that Cai Yong's expression was still contemplative and speechless, but Li Yi and Yu Bing showed strange looks, Zhang Ying's heart was different, could it be that he said something wrong? But most of the words have been spoken, although she muttered a little in her heart, she continued the unfinished topic on her lips: "This dark energy, which accounts for about seventy percent, really does not miss the slightest trace, it should be inferred artificially." ”

"Yes!" Yu Bing, who was smiling, couldn't hold back any longer, she grabbed Li Yi before he opened his mouth and said, "Dark energy is artificially assumed. Based on the Big Bang theory, the average density of matter in the universe, and the Schwarzschild radius of the universe, the total amount of detectable and expected matter discovered cannot be justified. Increasing this seventy percent of the dark energy satisfies the Big Bang theory, so it is assumed that most of the energy is hidden and has not yet been discovered. ”

Yu Bing also knows a little about astronomy, and all the gains come from Li Yi's mouth, and what she said is also described by Li Yi, but her memory is not bad, so she memorized it roughly.

Glancing at Li Yi, seeing that he nodded slightly, Yu Bing's confidence increased by two points, she showed a confident smile, and said with a firm expression: "This dark energy doesn't exist at all!" ”

"Ahh Zhang Ying couldn't help but shout out in frustration, she rarely lost her temper, so she was surprised when she said it from Yu Bing's mouth. What the? Dark energy doesn't exist? How is this possible? How many scientists have reached a consensus, how could it be wrong?

But how smart Zhang Ying's brain reaction was, she immediately realized that such connotative words were definitely not Yu Bing's thoughts, and she looked at Li Yi without hesitation.

Hearing Yu Bing's astonishing words, Li Yi frowned slightly, he swept the three people present, Cai Yong ignored the discussion of the three, but Yu Bing and Zhang Ying both looked at him with expectant eyes. (To be continued.) )
