Under the quiet night, Di Jun raised his hand up. In an instant, the stars were flying before their eyes, and time and space were chaotic. They seemed to be trapped in some kind of mirage environment. When they came back to their senses, Mo Guyuan and Bai Li were already there. In the ethereal darkness, I couldn't see my fingers.
Fortunately, the two held hands and never let go, and then they felt each other's presence.
"My little friend, look carefully. The Big Bang is about to happen." Di Jun's hoarse voice sounded slowly in the darkness.
It was a drop of light and shadow that destroyed the world and bloomed quietly from the darkness. It didn't make an earth-shattering sound, not even a trace of movement. It just bloomed silently and exploded.
What caught the eyes of the two people were various kinds of colorful lights. The energy contained in them had already exceeded the existence of any kind of heavenly material and earthly treasure in the world. Even a light group the size of a fingertip brought Mo Guyuan... Feelings are enough to destroy any existence.
The two of them stared blankly at the scene of the explosion of the universe. The streams of light scattered in all directions, passed through their bodies, passed through their eyes, and then flew towards the more vast and boundless darkness.
Bai Li was confused and hesitant. The intertwining of light and shadow in front of her eyes was a scenery she had never seen before. Compared with the ten-mile peach blossoms in Qingqiu and the stars in the universe, it was much more shocking.
Mo Guyuan watched the various different light energies collide and dissipate, turning into dust in the vast and deep universe and gathering again, until the grain of light came and merged into each other's structures. Over the long years, Combined with each other, they evolved into strange and bright stars.
Mo Guyuan was so fascinated by the sight that he wanted to stretch out his fingertips to touch the stars, but with just one stretch of his hand, it seemed like tens of millions of years had passed. When he was close at hand, he had already seen what was in front of him. The stars turned into a blue planet, where ancient civilization was beginning to form.
"It's the earth..." Bai Li whispered softly.
Mo Guyuan was stunned for a moment, then looked around, and saw that in the dazzling universe, there were countless galaxies that were roughly the same as what he was looking at, but most of them were different shapes, long or short, and similar in shape. The outline of the human figure has a posture similar to that of a horse, and there are also many whirlpool-like structures, which are all strange and fascinating to the eye.
Looking longer, Mo Guyuan suddenly looked towards a place outside the solar system. For some reason, he seemed to feel that there seemed to be some familiar breath calling him from the end of the universe, which made him confused.
"You and I are all children of the stars. Every cell in our body writes the history of the entire universe. When you gaze at yourself, you also see the outline of the universe. My little friend, have you ever seen the beginning and end of all this? "Di Jun's voice echoed in his ears again.
Mo Guyuan took a deep breath, still looking at the end, and asked puzzledly, "Where did the exploding light go? But it disappeared?"
"The universe is still expanding infinitely, and the speed is getting faster and faster. Of course, the millet of light cannot disappear, but the distance is too far. Even in my shrunken astrolabe, I still can't capture the disappearing light."
Mo Guyuan frowned and asked curiously, "Is it true that the universe still has no boundary and end?"
The surroundings suddenly became silent. After a moment of silence, Di Jun said hoarsely, "I don't know the details. There is no answer to the end of the universe. However, with the earth as the center, it is currently called the observable universe. The boundary of the observable universe It is a full 46.5 billion light-years away from us, and this is the premise of observing from one end of the earth. If we say that the entire boundary is doubled, it is a full 93 billion light-years."
The two of them were at a loss and had no idea about the so-called time limit.
"Looking at the entire universe, although there are countless planets, in terms of the universe, they are too small, just like a huge space filled with countless dust. It is the light of the millet that illuminates us. I can clearly see many existences that are invisible to the naked eye, including planets, galaxies, nebulae, and stars."
Mo Guyuan looked at the intertwining of galaxies in the distance. It seemed that every moment was endlessly running for the birth of life. There were also aging galaxies that collapsed and exploded again over the years, turning into dust and floating in the void of the universe.
At this moment, Mo Guyuan suddenly thought that not only everything in the world he lived in came and went, but everything in the universe and the galaxy were also experiencing all this. They continued to evolve and change, and finally turned into ashes and dust, dissipated, and gradually merged and were born. .
Immortal, immortal, immortal.
"Is there no end to all this? It has always been reincarnation infinitely, but in a different way?" Bai Li asked in confusion.
"Maybe there is, maybe there is not, but maybe we will never see it that day, or maybe the creatures in the universe will not have the chance to see each other again on that day."
Mo Guyuan shook his head, not daring to delve into those unreachable existences. The more he thought about it, he suddenly found that his state of mind was a little turbulent, and even showed signs of collapse.
"Senior, just now you said that our earth is the center of the universe. Did the Big Bang evolve from the earth?" Mo Guyuan asked subconsciously.
Di Jun explained, "In fact, that's not the case. We just want to infer the boundaries of the observable universe. We start from the earth itself and make rough calculations. On the other hand, if there are life forms in other galaxies, they also want to measure the size of the universe. Then the center of the universe is naturally with them."
Mo Guyuan was stunned and said, "Where did those group of alien demons come from? I just took a look at the solar system. Except for the earth, I didn't seem to notice any signs of life on other stars?"
As soon as he finished speaking, the scene in front of him changed once again. Mo Guyuan found that the scene in front of him shrank sharply. The entire solar system that could have been viewed suddenly became an insignificant spot of light in his eyes, and was replaced by a whirlpool. galaxy.
"This is the Milky Way, right?" Bai Li said thoughtfully.
"Yes, specifically, the Milky Way is a galaxy with rotating arms. You have also seen the structure of other galaxies before, with various shapes. The overall shape of the Milky Way is a whirlpool because there are four large arms in it. Constantly rotating, these four large galaxies are the Cygnus Arm, the Perseus Arm, the Sagittarius Arm, and the Southern Cross Arm."
The two of them looked intently and saw that, as Di Jun said, there were four galaxies like arms surrounding the Milky Way.
"The Milky Way is so vast that even our solar system is just like dust in it, let alone the Earth. In addition to these four big arm galaxies, there are also countless small arm galaxies mixed in, and the solar system is in one of these small arms. On the arm galaxy, we call it the Orion Arm."
"In the Milky Way, there are endless galaxies and countless stars. But even so, even in the Milky Way, it is still vast and vast, and the distance between galaxies and stars is still out of reach."
After saying that, the screen zoomed out again, and what came into view was another very large galaxy. Next to it, the Milky Way looked half as small.
"This is the galaxy closest to the Milky Way, called the Andromeda Galaxy. It is more than twice the size of the Milky Way. According to the observable universe, there is another large galaxy outside the Andromeda Galaxy. It is ten times larger than the Andromeda Galaxy. Many times, as for the name, we can refer to it as Galaxy 101 for the time being."
"According to the distance, the Andromeda Galaxy is about 2.5 million light-years away from the Milky Way. Due to the huge structure of the Andromeda Galaxy, it is currently approaching the Milky Way at an extremely fast rotation speed. If we wait until one day in the future, the two major galaxies may be separated. They may collide and merge into one."
With two major galaxies in front of him, Bai Li tried hard to cross the galaxy to find the existence of the earth in the solar system. In the end, he found that the earth was shaped like a mustard seed and was too small to be worth mentioning.
The scene turned, and another large galaxy appeared next to the two.
"This is the Triangulum Galaxy, plus the Milky Way and the Andromeda Galaxy. These three are combined to form the Local Galaxy Group. This is just one Local Galaxy Group. To magnify it, add a hundred Local Galaxy Groups. Also called the Virgo Supercluster."
In front of my eyes, scenes of stars are changing. When I zoom out again, even the Milky Way disappears from sight. The local galaxy group composed of three major galaxies has become an insignificant point of light. In the Virgo Super Galaxy Cluster, everything is gone. It's so small.
The two of them seemed to be in a dream, not knowing where they were.
"Do you think this is the boundary of the observable universe?" Di Jun was silent for a while and then evolved the cosmic star disk again.
The next moment, a huge golden shimmer was seen, enveloping the Virgo Super Galaxy Cluster.
"This is the Laniakea supercluster. Except for the Virgo supercluster in the middle, the blue light and shadow on the far right is the Hydra Centaur supercluster, and the red light and shadow on the left is the Peacock Indian supercluster. Originally, these three Each supercluster is an independent galaxy cluster, but in the vast expanse of the universe, the distance between the three is slowly getting closer, so they are unified into the Laniakea supercluster."
Mo Guyuanhu asked, "Since the universe is so big and is still expanding infinitely, why don't these three super-galaxy clusters rotate towards the periphery and move closer to each other?"
"That's because there is an extremely powerful gravitational force attracting these three super-galactic clusters, constantly pulling the distance between them, so they slowly approach. We call this gravitational force a giant force. Source."
"Giant source of attraction!"
"Yes, apart from the earth, the life forms you mentioned earlier have not been found at least in the Laniakea Super Galaxy Cluster, and the group of alien demons came from the giant attraction source. No one knows where the gravitational cracks came from, but those outsiders really came here from the giant source of gravity, and finally landed on our Five Classics of Mountains and Seas." Di Jun's tone began to become serious. stand up.
Mo Guyuan and Bai Li stared blankly and saw that there was indeed a dark purple slit in the middle of the three super galaxy clusters. It was like an eye opening a slit, revealing an evil aura of power.
Mo Guyuan looked deeply and became a little distracted.
"Is this Laniakea supercluster the scope of our observable universe?" Bai Li muttered to himself as he looked at the golden light in front of him.
As soon as the cosmic star disk darkened, the surroundings were once again plunged into darkness. However, compared with the previous time when I couldn't see my fingers, although it was dim now, fortunately, I could still see many light spots floating in front of me.
"This is the appearance of the observable universe. It is a universe composed of ten million Laniakea superclusters."
