Following Li Shuang around the small foreign building and passing through solid barriers one after another, the three of them walked into the real core of Xi'an.
In the darkness, a miniature version of the Earth appeared, suspended in the center. Four wheel-shaped urban areas were in orbit synchronized with the rotation of the Earth. Six canopies were buckled on the earth, like six giant upside-down bowls. The Fuji was slightly smaller. , docked near Denali City’s canopy.
Every spacecraft of the Interstellar Expeditionary Force, the Deep Space Defense Corps, the Temple Guard Corps, and the Guard Robot Corps are clearly visible, and most of them are gathered in the sea area where the Zhenjie Fort is located.
In low-Earth orbit, the broken Galaxy is being repaired. It can be vaguely seen that tiny robots are crawling all over the hull, and weak sparks are constantly shooting out. The Ahiya and Lanikea are flying away from the earth. Towards the moon not far away.
The moon is also extremely realistic. The side facing away from the earth retains the original landform, and the side facing the earth is wrapped in a mesh structure. At this moment, the mesh structure is translucent, and you can see that the upper city of the moon is divided into areas. Each area The regional landforms and environments are different, with snow-capped mountains, deserts and grasslands reflecting different colors.
The earth and moon are surrounded by dozens of star fields, marked with the Otter Nebula, Centauri, the Sirius Double Star, Wolf 359, the Perseus Arm, the Sagittarius Arm, etc., and every human place is marked in these star fields. The established mines and observation bases, especially the Otter Nebula, are dotted with more than a dozen large-scale mining operations.
There are nearly a hundred distant galaxies on the periphery of these star fields, connected into a spherical shape. Each galaxy presents a unique shape, full of a confusing sense of order, and does not look like a natural formation at all.
Outside the galaxy, there are thousands of stars and the vast deep sky.
At the very edge, there is a lonely base marked: 'Observable Universe Boundary Station (2645)'.
The four of them walked among the stars.
Is this the whole universe?
Li Liang walked near the "Border Station", stared at the pure darkness outside the "Border Station" and asked: "What's outside? What's outside?"
"Dark matter clouds with zero mass," Li Shuang's voice sounded faintly, "As these absolutely stationary dark matter transform into baryonic dark matter that participates in electromagnetic interactions and non-baryonic dark matter that only participates in gravitational interactions, the universe continues to expand and its boundaries continue to expand. .”
Cain said blankly: "Is there only darkness outside the universe?"
"No, just to avoid display confusion," Li Shuang smiled, "Actually, the boundary of the observable universe is very bright and colorful." He clicked on the label "Observable Universe Boundary Station".
In an instant, the stars changed, and the 'border station' replaced the earth and became the center of space. A clear dividing line appeared on the right side, like a colorful ribbon, winding and changing.
The light illuminated the faces of the four people.
for a long time.
K asked in confusion: "How long does it take to get to this base?"
Li Shuang waved his hand, and a curve began to extend from the vicinity of the earth: "If you take the Asia spaceship and set off from the earth, you will experience acceleration, quantum slipstream, warp jump, deceleration, and arrive at the ASASSN-15lh supernova in the Indian constellation 3.8 billion light years away from the earth. Nearby, if this process goes well, it will take one hundred and forty-five years, seven months, three days and three hours, and then..."
The curve ends abruptly near a bright patch of interstellar dust.
"...activate the Needle of Asia, enter the space where the metric tensor expands into a probability cloud, and then arrive at the boundary station 93 billion light-years away from the Earth at Planck time, which is 10E-43 seconds later."
As soon as he finished speaking, the end point of the curve and the border station flashed at the same time.
K and Cain had no special reaction because they didn't understand it at all. However, Li Liang knew very well what the process described by his brother meant.
He wondered: "I actually never understood why the Axia can exceed the speed of light? Is the special theory of relativity wrong?"
Li Shuang lowered his head and said slowly: "I don't know."
"ah?"
"At the beginning, the Time Observer provided ten formulas, involving metrics, the conversion relationship between different inertial reference systems when observing physical quantities, the Higgs field, the uncertainty principle, etc., which completely subverted my understanding of the laws of physics. With my knowledge, I solved most of the known puzzles through these complex formulas.
In addition, they also provided a metallurgical method to mine and utilize the mysterious metal under the moon's Aikent Basin. This metal has a wide range of applications. I used it to make the Needle of Asia..."
Li Liang suddenly realized that it turned out that the Time Observer not only conducted a forced closed-loop experiment and brought the 'ascension potion', but also provided formulas. It was these formulas that enabled Xi'an to master technology far ahead of his time.
In this case, why did the younger brother say "I don't know"?
"You know the formula, but you don't know the principle?"
"Yes," Li Shuang shook his head, "We rack our brains to understand the objective reality, just like a person facing a closed watch wants to understand the internal mechanism of the watch.
He saw the dial and the moving hands, and even heard the ticking sound, but could not open the case to see. So, he conceived a mechanism that could explain all the phenomena he observed. However, he could never conclude that except for him No other method could explain the phenomena he observed, and he could never compare his conception with the actual situation, or even conceive of the significance of such a comparison.
From ancient times to the present, the universe has been a closed watch to us. We observe the universe, summarize different laws, and verify them through experiments. With the advancement of technology, we will always observe new phenomena, so we propose new To explain, in a sense, the theory of relativity is no better than the heliocentric theory, because Einstein still did not open the watch.
The formula provided by Time Observer opened the cover of the watch and allowed me to see some internal structures. At the same time, it also allowed me to see that there is a closed core inside the watch.
These formulas can explain most of the phenomena observed by humans, but I am still not sure. Are these formulas the truth of the universe? Why? What do the constants in the ten formulas represent? Why are they constants?
So, brother, I can explain how the Needle of Asia exceeds the speed of light and breaks through the four-dimensional rigid continuous space-time. However, if you ask me why, I can only answer, I don’t know. "
Li Shuang waved his hand, and dense symbols appeared.
"These are the ten formulas."
Li Liang looked around. Let alone understanding, he couldn't even tell that the large number and symbols represented ten different formulas.
He turned to look at K and Cain.
Cain was seen lowering his head and playing with Oumuamua's hair. K noticed his gaze and asked seriously: "What is the speed of light?"
"..."
Li Shuang smiled: "The propagation speed of light waves or electromagnetic waves in vacuum or medium in four-dimensional rigid continuous space-time."
"Oh," K nodded, "How fast?"
"About three hundred thousand kilometers per second in a vacuum."
K said in surprise: "So fast."
"..."
Li Liang rubbed his forehead.
At this time, Dr. Xisen should be brought here, so that we can sigh with him about the weirdness of science.
Li Shuang said softly: "After the spiritual door is opened, we may be able to find the answer in the spiritual world."
"Really?" Li Liang raised his eyebrows.
"Well, researchers in magic and Taoism have completely different understandings of the basic world. For example, the quantum transmission equipment we manufacture has an effect close to the portal in magic, or the transfer technique in Taoism, but the principles are completely different. Different, like two different theoretical explanations for the same phenomenon."
Li Liang nodded, and with a wave of his hand, the orange fire spread and formed an oval-shaped portal, which lasted for more than ten seconds and gradually dissipated.
"Well, magic has many characteristics that subvert our cognition," Li Shuang said with a smile, "Before you returned from Axia, you moved in a flashing way. Your speed far exceeded the speed of light, and you did not respect mass at all. Conservation, you must know that the earth is not stationary, but moves in the universe following the Milky Way. The speed relative to the cosmic microwave radiation background radiation in the stationary system is about 370 kilometers per second. At the same time, the human brain cannot effectively determine time of 1/60th of a second. interval, so theoretically, if you move forward instantly, you will deviate from the destination by more than 6 kilometers.
The fact is that you, including all materials that come into contact with your body, appear exactly at the preset position without any deviation and without generating huge radiation energy. For you, the laws of physics seem to be completely inapplicable. "
Li Liang had never thought about this kind of problem and asked curiously: "Why is this happening?"
Li Shuang spread his hands: "I don't know."
"..."
Li Liang realized that in addition to learning magic with Dododisar, he also wanted to buy all the books on magic and Taoism next time he went to Makosik or Du Yujing, and then asked his brother to organize a Get some people to study it carefully.
Putting aside the chaotic thoughts, he remembered the purpose of coming here, turned around and asked: "What do you mean by changing the earth?"
Li Shuang hesitated for a moment and said slowly:
"The sandstorms and radiation that have lasted for hundreds of years on the surface...were actually created by us and can be stopped at any time."
"What?" Li Liang's expression suddenly changed and he asked in a voiceless voice, "What did you say?"
The earth returned to the center of space, quickly zoomed in, and countless areas lit up, spreading across the globe.
Li Shuang raised his head and said: "We have set up controllable radioactive sources in these areas. In addition, each canopy is equipped with a weather system, which continuously disturbs the atmosphere and forms storms around the canopy..."
