"That's right. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 infoSo I came up with a modified model, the cosmic sphere is made up of two layers of spherical shells, and the sky we see is the inner shell, and there is a big hole in the outer spherical shell, and there are a lot of small holes in the inner spherical shell, and the light from the big hole in the shell is reflected and scattered in the interlayer between the two spherical shells, so that the interlayer is filled with bright light, and this light penetrates through the small holes, and we see the stars. Mozi smiled.

"What about the sun?" The blue cat asked.

"The sun is a huge spot of light cast onto the inner shell by a large hole in the outer shell, and it is so bright. Shining through the inner shell like an eggshell, we see the sun. The scattered light around the spot is stronger, and it also illuminates the inner shell, which is what we see as a clear sky during the day. Mozi explained.

"What is the force that most drives the irregularity of the two spherical shells?" The blue cat asked again.

"It's the power of the sea of fire beyond the universe." Mozi replied.

"But the size and brightness of the sun are different at different times. In your double-hull model, the size and brightness of the sun should be constant, and if the outer sea of fire is uneven, at least the size should be constant. Blue Cat said.

"You think of this model too simply, as the outside sea of fire changes, the size of the outer shell of the universe will also expand or contract, which leads to changes in the size and luminosity of the sun." Mozi chuckled and shook his head.

"What about the flying stars?" The blue cat asked sharply.

"Flying star? Why do you always mention flying stars? They are some unimportant west, dust flying around the universe. Mozi was a little unhappy.

"Nope. I think flying stars are important. Also, how does your model explain the fact that the sun went out in the sky during the time of Confucius? The blue cat went toe-for-tat and raised his voice several degrees.

"That's a rare exception, maybe a dark spot or black cloud in the sea of fire outside the universe that happens to float through a large hole in the outer shell." Mozi replied leisurely.

The blue cat stretched out his hand and pointed to the copper ball and said, "This must be your model of the universe, right?" ”

"Yes, I built the Space Machine. The complex set of gears that rotate the ball simulates the action of the outside sea of fire on the ball. The law of this action, that is, the distribution and flow of flames in the sea of fire outside, is what I have summarized after hundreds of years of observation. Mozi looked at his masterpiece.

"Can this ball expand and contract?" The blue cat asked.

"Of course, it's slowly shrinking right now." Mozi used his hand as a reference object to compare it, so that people could see the movement of the big copper ball.

The blue cat took a closer look and found that what Mozi said was the truth.

"Does this ball have an inner shell?" The blue cat asked.

"Of course, there is, and the inner shells are driven by complex mechanisms." Mozi spoke, his voice high.

"What a clever machine!" The blue cat couldn't help but admire and asked, "Can you see the big hole in the inner shell that casts light spots from the shell?" ”

"There were no holes, and I installed a light source on the inner wall of the enclosure as a simulation of the big holes. The light source is made of fluorescent materials extracted from hundreds of thousands of fireflies. The light emits cold, because the translucent gypsum sphere of the inner shell does not conduct heat well, which prevents the general thermal light source from accumulating temperature in the ball, allowing the recorder to stay in it for a long time. Mozi said.

"There's someone else in the ball?" The blue cat was a little dumbfounded.

"Of course, the recorder stood on a shelf with pulleys at the bottom, and the position remained in the center of the sphere. After setting the simulated universe to a certain state of the real universe, its subsequent operation will accurately simulate the future state of the universe, and of course, the state of the sun, which the recorder recorded to form an accurate perpetual calendar, which is something that hundreds of civilizations in the past have dreamed of. You have come at the right time, the simulated universe has just shown that a four-year-long era of eternity will begin, and Emperor Wu of Han has issued an edict of immersion according to my prediction, let's wait for the sunrise. Mozi explained the doubts.

Time has gone faster.

The red morning sun appeared in the sky, and the dense white dust on the earth began to change, and the ice inside was shattered and turned into flowing water, and the lake shimmered with phosphorescent light appeared.

Immediately black stars appeared, and the blue cat knew that the scene of cheering from the past had reappeared.

"Won't you go down and devote yourself to this wonderful life? Women who have just been resurrected are the most eager for love. Mozi pointed to the vast land and the newly-born people of Li and said, "There is no point in you staying here any longer, the era is over, and I am the final victor."

"Your simulated universe is really wonderful as a machine, but what about the predictions you make about it...... Oh, can I use your telescope to observe the sky? Blue Cat said.

"Of course, please."

Mozi waved his hand, looking very casual.

The blue cat came to the telescope, paused slightly, turned around and asked, "What should I do if I want to observe the sun?" ”

Mozi walked to a wooden box, fumbled for a black lens, came to the eyepiece of the telescope, plugged it in, and said, "Add this smoky filter." ”

The blue cat stood in front of the telescope and looked at the sun rising into the sky, the sky was indeed very much like what Mozi said, the sun was just an opening to the boundless sea of fire, a small part of a great being.

The blue cat pulls up the magnification of the telescope, and the farther it looks, it sees a different image.

Different from the sun on the earth, there is a central point in the bright package, which is clearly hierarchical, and it is compared to the eye, then this central point is the pupil.

The solar core is not large, but most of the light is brought by it, and the brilliance is a little faint, it seems to be a large glowing air, and the pronucleus in the center can be seen, which also means that the brilliance is not compact.

It is very likely that a lot of the sun's rays shining on the earth are emanating from the pronucleus, and have little to do with the huge brilliance.

The impossible but real image made the blue cat breathe deeply, and also made the viewer have a trance, everyone knows that Mozi is wrong again, and this era is coming to an end.

The blue cat stood up and looked directly at the sun, with pleasure, because he had discovered part of the truth, he just stood in front of the telescope, constantly observing the bright sun and the twinkling starry sky.

Scene after scene, sunset and stars, occasionally flying stars flash, the lens of the telescope followed it through the night after night.

In this way, more than ten days passed, and all the audience clearly saw the trajectory of the long stars in the dark night, and they all examined the secrets hidden in them with great interest.

In these days, Mozi is also struggling to make the first perpetual calendar in this world.

Seventeen days after the Eternal Era, the sun did not rise and lasted for five hours.
