Liu Bowen has always deduced the star map and the order of the five elements of yin and yang, and he has a lot of experience, but this overlooking astronomy and geography, later generations know, and what he sees is detailed to his predecessors. However, mortals look up at the sky, but they only see a glimpse, such as the frog at the bottom of the well, Liu Bowen knows that even if he really has the ability to penetrate the heavens and the earth, he is afraid that it is tantamount to peeping at the leopard in the tube.

He had heard Xiao Liang say something about the continent and the ocean a few days ago, and he felt quite insightful, so he was fortunate enough to ask today.

Liu Bowen said: "Although I look up at the celestial phenomena below, I just rely on a pair of human eyes, and how these stars operate is only an observation and inference. ”

Xiao Liang was taken aback, he knew that this Liu Bowen had the talent to learn from heaven and earth, but such a person actually came to ask him for advice, his heart was extremely nervous, and he hurriedly sat upright, and thought of the ancients' study and knowledge, and was secretly surprised.

"Mr. Liu, I don't study well, and if I think about it, I only know a rough idea. Xiao Liang smiled.

Mrs. Hu said: "Yes, yes, you mortal, what's the use of knowing so much! The more you know, the more troubles and troubles you will have." What's the point of really figuring out everything in the world? ”

Liu Bowen smiled with a smile: "Eh, people don't stop lusting, and since they are mortals, they naturally have some obsessions." I saw Liu Bowen take out a picture and hand it to Xiao Liang and said, "There is a picture here, how about the little girl help me take a look?"

Zhang Xiaoliang's eyes widened, and he didn't know what kind of problem Liu Bowen could come up with with him, so he saw that on this picture, there were many balls drawn from the inside to the outside, the innermost ball was the largest, and the outward was of different sizes, all of which seemed to be orbiting around the largest ball.

"This is! This is the solar system!" Xiao Liang was taken aback, she knew that this theory of the circle of the earth and the theory of heliocentrism were put forward by foreigners hundreds of years later, and this solar system was only glimpsed in modern times, but as an ancient, Liu Bowen, talked and laughed and drew the star list clearly, which started from the sun, Mercury, Venus, Earth, Mars, Jupiter, Saturn, different sizes from near to far, marked exactly the same, and Uranus and Neptune, although the names are different, but the position is roughly the same.

Xiao Liang was surprised to take a closer look, and saw moon-like moons, as well as some moons of Jupiter and Saturn, and couldn't help but be stunned.

Liu Bowen said: "The solar system?"

Xiao Liang said: "Yes, it is a galaxy centered on the sun, and the earth where we are located is in this galaxy!" Xiao Liang asked: "Sir, dare to ask if you drew this picture, or did you find these things?"

Liu Bowen said with a smile: "That's not the case, the pictures here are all based on my predecessors' summary, sorted out, but many of them are really known to children, but there are many incomprehensible points, and now I see Xiaoliang girl, and I hope to give you some advice." ”

Xiao Liang thought for a moment and said: "It turns out that there are many discoveries and innovations that Westerners are proud of in this world, but they are already rotten streets in China. I really don't know what modern people in the future want to write about, their own moon is obviously big and round, but they have to envy the moon of other families. Xiao Liang nodded and said: "That's right, sir, the picture you drew is the solar system we are in now, the earth we step on, and modern people will call it the earth in the future, and it should be the earth."

The ball is round. ”

Liu Bowen said: "Yes, the four o'clock flows, the sun and the moon change, and the cycle repeats, the earth is indeed round." ”

"The earth is also a celestial body, and the celestial bodies have their own definite trajectories, the sun is a star, the earth and other celestial bodies such as gold, wood, water, fire, and earth are planets, and the moon and the like are called satellites, satellites revolve around the planets, and the planets revolve around the stars. Cycle after cycle, year after year!" Xiao Liang said.

"Oh, year after year, cycle after cycle..."Liu Bowen suddenly thought thoughtfully.

Xiao Liang said: "Many of the stars we look up at now are glowing stars, and almost every star has its own galaxy around it, and the sun is not too big in it! And in the more than 4 billion years of the earth, it is only a moment in comparison with the universe. ”

Speaking of this, Liu Bowen couldn't help but be surprised, and sighed: "Oh, the heaven and the earth are magnificent, the universe is boundless, the grasshopper is only a moment compared to people, and people are just small stones and small trees between heaven and earth, and heaven and earth are like sand and gravel between the universe, I really don't know how big this universe can be." ”

Xiao Liang said: "Eh, that's really too big, our earth is a sphere, from the equator, it's just more than 80,000 miles long." And there are 600,000 miles between the earth and the moon, and even the light has to walk for a second. ”

"One second?" Liu Bowen explained.

Xiao Liang said: "It's almost a blink of an eye, just what we think is the fastest thing in the world, you and I must see each other in a moment, because of the speed of light, but there is also a blink delay between the earth and the moon at the speed of light, and the light of the sun will take more than half a quarter to reach our earth, and the solar system where we are located is the light will also take two or three days." ”

Xiao Liang said and gestured, and from time to time she wrote with a brush, her natural science was so-so, but when she talked about it, it was endless.

Liu Bowen and Third Master Hu listened carefully, Liu Bowen knew the size of this stool, but it was even more incomprehensible, so he said: "The vastness of the universe, even the beam of light has to travel for several days, so wouldn't the entire galaxy take this light to travel for a year?"

Xiao Liang couldn't help but be silent, thought for a moment and said, "Eh, sir, there are hundreds of millions of stars in the galaxy... I'm afraid it's hundreds of thousands of light years long!"

"Oh, hundreds of thousands! Oh my God, it's unbelievable, it's hard for the human brain to imagine. Liu Bowen said.

Mrs. Hu listened attentively and drank Liu Bowen's tea cleanly, Xiao Liang saw that he was eating happily, and took out the snacks she made in the morning for Mrs. Hu to eat tea, and Mrs. Hu was very happy and feasted.

Xiao Liang patted him on the back for fear of choking, Xiao Liang said, "Yes! And beyond this galaxy, I am afraid there are many galaxies similar to the Milky Way. ”

Liu Bowen nodded, and his heart suddenly brightened up and said: "Hahaha, there are subtleties in the human body, and this universe is also infinitely vast, if these countless galaxies like galaxies converge into the universe, I am afraid that there are countless universes outside this universe!

The constraints of time, standing outside the void, can go back and forth between the past and the present! Little cool girl, do you see what I said right!"

Xiao Liang was taken aback, and her heart continued until this Liu Bowen was really a fairy, she herself just said the theory of the universe simply, this Liu Bowen not only understood the truth clearly, but even deduced the theory of parallel universes and multi-dimensional spaces, and couldn't help but stare at it in a daze and muttered: "Mr. Liu, you are simply an immortal!"

Liu Bowen said with a smile: "Hahaha, it's okay, Zhuangzi has a saying: small knowledge is not as good as big knowledge, and small years are not as good as big years." What I know today is only a small knowledge. What is beyond the reach of the primeval world, and what is not in the future, is a difficult opportunity to peep, and how can human beings know everything. Liu Bowen thought about it himself, and suddenly a flash of inspiration occurred, but he muttered: "I'm afraid the fortune of all this has already been decided." ”

Xiao Liang frowned and muttered, "Maybe, maybe everything is predestined." But Gu Yun said that life is self-seeking, and happiness is self-made. What the hell is to be?"

Liu Bowen said: "Yes, this celestial and human induction, China has already existed, Fu Xi comprehends the heaven and earth and sits in the gossip, this universe and stars also correspond to Qimen, if these starlight are hundreds of thousands of years ago, then these celestial and human established induction is not already destined in the dark? And the three walls, four elephants, and twenty-eight nights are all in the hexagram gate. And if Miss Xiaoliang you travel back and change history, then you will not travel in the future. If you don't go back in time and change history, how can history change?"

Xiao Liang was stunned and couldn't answer: ".... Mr. Liu, your question is too profound for future scientists to answer!"

Third Master Hu smiled and said: "Hahaha, yes, yes, that's why mortals, you know so much, it's just to add to your troubles! Look at your "check"? It's so delicious, I'll give you this baked cake to eat!"

Liu Bowen wisped his beard and muttered puzzledly: "Baked cakes, baked cakes?" and looked at the sesame seeds on the baked cakes like stars, and suddenly felt enlightened, and immediately got up and gave Xiao Liang a deep bow: "Mr. Xiao Liang, I have been taught today, and someone Liu has been taught." ”

Xiao Liang panicked and hurriedly went to help: "Where and where, I am looking at these things, they are all random on weekdays, Mr. Liu can't help it!" Xiao Liang panicked, and looked at Liu Bowen's face as if he had a gain, and smiled stupidly.

Liu Bowen accepted the baked cakes of Third Master Hu, delayed eating them and put them in the box, looked at Xiao Liang's face, and then looked at the jade dragon on Xiao Lianghao's wrist, and couldn't help but sigh.

Xiao Liang was stunned for a moment and said, "How is sir?"

Liu Bowen said: "The girl's physique is weak, I'm afraid it won't be a long-term condition... But there is a hint of warmth in the complexion... It's really like a blessed person. ”

Mrs. Hu said without seriousness when he was eating: "This girl is a good girl, what a blessing, I went to check on her above, at most there is another three or four years of life, she is a person who has died twice." Where else is there any blessing..."

Xiao Liang frowned when he heard this, and muttered, "You guys, don't talk to Gu Yun." ”
