.

There are countless shiny dust particles in this small cosmic cloud, and countless radio wave galaxies emit pleasing blue, red, gold, yellow, green, blue and purple colors in the small universe, and their jets from the center of the radio wave galaxy are accelerated by the supermassive black hole, which is extremely bright at radio wavelengths, and looks like a grand carnival in deep space. Like many splendid and beautiful things, radio galaxies are short-lived, and such a crazy jet of matter will soon deplete them, and they will fade away as if they had never come. Of course, the black hole in the middle of the galaxy will also be active again, rekindling the entire galaxy, like lighting a lone lamp in the dark.

In the small universe full of spinning cyclones, the Milky Way can be clearly seen from a corner near the edge, and there is the Milky Way Realm where the gods live, it is surrounded by a huge halo of hot air, its diameter is estimated according to the scale of the small universe data, reaching hundreds of thousands of light years, like a child sleeping in winter, and the surrounding hot air mass is its thick quilt. The vertical waves produced when dark matter galaxies pass through the Milky Way lead to significant changes in the structure of galaxies. Like a brass bell that has been struck, it still vibrates regularly, and the stars in the system are bouncing at high speed, as if countless shiny glass beads are falling on the floor.

In this small universe, it can be clearly seen that the closer the stars are to the center of the Milky Way, the greater the amplitude of their upper and lower vibrations, and the spiral arms of the Milky Way are rotating slightly, like the outstretched arms of a dancing girl in colorful holy clothes; there are many stars like sand and dust on the spiral arms that glow blue, and the sun belongs to the insignificant kind of stars in the universe, it is small enough to die in a brilliant explosion, but humble enough to be blown out at any time with a pop like a candle in the wind. Located 25,000 light-years from Earth, the Penta Star Cluster is one of the most spectacular sights in the Milky Way, like a cosmic kindergarten that nurtures countless young and vibrant stars that have just formed and are bright and dazzling. The stars in the quintage cluster are quite dense, and streams of material ejected from massive stars that are very close to each other collide with each other, causing violent combustion and erupting red or blue flames. The pentagram is the largest, densest, and brightest star cluster in the Milky Way, it is obscured by a large amount of white-hot gas and dust around it, because the pentagram cluster is close to the center of the Milky Way, and is close to a supermassive black hole in the constellation Sagittarius, so it is torn by gravity all the time, and the escaping star cluster shows off with a warm fire, extending out, like colored hair blowing in the wind.

At the same time, due to the gravitational pull of neighboring galaxies, many spiral galaxies like the Milky Way in the small universe are being twisted into irregular galaxies by other spiral galaxies, like a combination of invisible stars and cosmic dust. Moreover, it can be clearly seen that the bright knots and the larger high-gas cosmic regions inside, as well as the boundaries formed by the larger stars, among which from time to time appear young and larger blue stars, which are surrounded by huge rings of dust and gas, and the translucent blue is quietly plated on this ring, glowing with a charming and beautiful light. In addition to the brilliant light color, you can also see an elliptical galaxy about 50 million light-years away from the earth, diffusing bright light in the deep sky, it is in this simulated three-dimensional small universe, just like someone in the distant dark night to light up a small flashlight, it is one of the 2000 galaxies near the constellation Virgo. ...... In the direction of the constellation Pastorius, there is a large empty area like no man's land, this area with a diameter of about 250 million to 330 million light years, there are only 60 galaxies, which is a barren land in space, as if the universe is isolated from the outside world, and then, in the infinite expanse of the outside world, there are countless similar universes, like countless parallel worlds.

Clusters of nebulae glow brilliantly in the small universe, slowly entangled, moved, and rotated...... , and between the nebulae is an endless void.

In the past, time and space were obstacles for children to understand the universe, as were the gases and dust that filled space, which blocked the light and cut off the most direct clues for children to explore the universe. And when gazing at this simulated small cosmic starry sky, it is like looking at a kaleidoscope for the first time, those colorful patterns fascinate the eyes of children, and what is displayed in front of children's eyes is like a three-dimensional and living picture!

The various clouds of galaxies swirling on this simulated small universe look so fascinating, like a living watercolor painting, it is extremely beautiful.

The children were stunned and fascinated!

Nalan Rouruo and several other female disciples unanimously praised: "This star is so beautiful! How good it should be to have such a beautiful star on our Forget Worry River!"

The old man looked at the children, smiled and said, "Children, this is the little stars you once looked up to, what kind of fantasy and splendor do you have in our small universe now? ”

"Children, this simulated small universe is the universe we can observe at present, the range is about 93 billion light years, this range is also called the 'observable universe', which contains 20,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000, In the face of the vast universe, the existence of human beings and various species in our other world is so small, compared to the entire universe, we are as inconspicuous as a drop of water in the ocean. But the universe is still expanding, so we don't know how big the universe is, and perhaps for the outside world, the observable universe is only a small part of it, and its existence is like sand in the desert. ”

The old man pointed to the spiral arm of the Milky Way galaxy that simulated the corner of the small universe and said: "This is the solar system where we are located, the diameter of the solar system is about 2 light years, and for the diameter of the Milky Way is 100,000 light years, the solar system is like a ping-pong ball put into a football field. Now we can look at the universe at a distance of 1 light-year, or even 100,000,000 light-years. Well, let's take a look. ”

"From a distance of 1 light year, a star the size of the sun looks small. At a distance of 100 light-years, there seems to be 'nothing' in the universe, and all you can see is stars and nebulae ......; 1000 light-years, from this distance, we begin to travel in the Milky Way and the Milky Way. At 10,000 light years, we continue to travel through the Milky Way. At 100,000 light-years, we're starting to touch the outer reaches of the Milky Way. At 1 million light-years, the Milky Way looks like the Buddhist "swastika" character, and we are on the spiral arm at the very edge of the Milky Way, very far away from the center of the Milky Way, where the legendary Sacred Realm civilization inhabits, and at the same time, we can see other galaxies ......; At 10 million light-years, all galaxies appear so small that you can think they're just a swarm of dust much smaller than dust, and the galaxies are extremely far apart. The whole universe is like an empty sea of darkness, and yes, the same laws govern every component of the universe, such as the microcosmic world. ”

The children turned their heads, looked at the old man, and asked suspiciously, "What is the microcosm? Master." ”

The old man looked at the children, spun the simulated small universe, took out a leaf from the small universe, and said with a kind smile: "Children, then you can imagine now, if we go back to the picture of the leaf in our grass courtyard at the beginning, we will become an object as small as an ant or countless times smaller than a millimeter, and walk into that leaf, enter a magical microscopic world much smaller than sand, and see the scene of the microscopic world inside the leaves." Of course, now you have not mastered the Golden Body Shaping Skill, and you cannot infinitely shrink your body, so you can only rely on your imagination now, and you will no longer demonstrate as a teacher, and if any of you have mastered the Golden Body Shaping Skill in the future, you can experience the microcosm by yourself and understand whether the macrocosm and the microcosm are the same. In short, we are just seeing a small corner of the universe. Kids, get the idea,"

"Master, how wonderful is this world?" the children looked at Master, revealing their desire and expectation for endless knowledge.

The old man stopped talking, he twisted his long beard in his hand, looked at the endless dark sky, and his thoughts were myriad, wandering into space.

It's big, it's small!

We are far from seeing the borders that can be reached. But it is certainly not yet the boundary of truth. It is not matter but energy that makes up this world, and how does energy come from and how does it work?

The Buddha said that one flower is one world, and he also said that all dharmas are empty, color is emptiness, "emptiness" is not nothingness, it is another kind of existence, "color" refers to all matter, and "Tao" thinks that one and two, two and three, three give birth to all things, and all things eventually return to emptiness.

So, now think about it, are you the center of the universe?

Are you a special creation of all things in the world?

What is it outside these borders?

Is there a so-called "border"?

Who can say that we have been able to solve all the mysteries of the universe and life?

The children looked at this infinite void but infinitely vast cosmic world, silent, and fell into deep contemplation of the world, life, and themselves.

After a long time, the old man broke everyone's silence, "Children, after this journey of heart and eye, let's go back and comprehend it." Now, it's time for us to go back, too. ”

The old man waved his sleeves to the simulated sky glasses in the crater, only to see a white light passing by, the small universe starry sky disappeared into invisibility, and the simulated sky glasses were also instantly invisible, turning into a colorful rainbow, built between the blue star and the moon, like a rainbow bridge, and the children entered the rainbow bridge one by one. A bright colored beam of light shone like lightning, and in an instant, the old man had already taken the children back to the Lingtai Thatched Hall in Qinggeng Mountain.
