Volume 3: Dance of the Aurora Chapter 31 The Night is Coming
I'm pushed by the wind
East and West
The sun disappears into the twilight
Night is coming
I sailed into the harbor of the Milky Way
Thousands of stars are looking at me
I left it behind
Crescent Moon - Anchor of Gold
Dawn
Ocean filled with cloudy icebergs
Hitting
"Boom boom" - thunder and lightning
I'm going there
The universe is so boundless~
——Gu Cheng, "Fantasy of Life"
In the vast Central and South Pacific Ocean, there is a small island made up of protruding rocks. It looks like a pimple growing on the bottom of the ocean, lying abruptly in the endless waves.
The surface of the island is extremely flat. Apart from fine and dense gravel, there is no other landscape and no trees can grow. Only a small area in the core can see a few faint green spots, and no one knows where their seeds come from.
The big hand of the tide caresses the island day after day, making the entire island appear to be a smooth ellipsoid. The rough surface is slightly raised from the sea level, and its shape looks like the bottom of a completely inverted wooden boat.
In the center of the island there was a thin dark figure, a young man with a haggard face. He was sitting cross-legged, supporting his chin with one arm, looking thoughtfully at the waves around him.
Fang Cheng has loved the sea breeze since he was a child. Whenever he has free time, he will go for a walk along the coastal road or on the pier, or sit on a bench and stare at the boundary between bright blue and dark blue in the distance, and listen to the sound of seagulls.
However, this scene is only available in summer. If you go to the beach near your home after November, the knife-like cold wind can blow your ears off.
However, there is no such concern in this tropical sea. The salty and fishy sea breeze mixed with sand and dust constantly bombards Fang Cheng's skin, and a moist and strong warmth pours into his collar.
This dirty, hot, humid and sticky environment, with a faint stench in the impetuous air, easily reminds people of the men's locker room in a public bath.
Oh, if only I could take a bath now.
Thinking of this, he recalled the cleaning function of the T-800, but now he was exhausted physically and mentally, and didn't want to experience the feeling of his entire body being completely submerged in metal again. When Fang Cheng and Ai Bishui separated, the ring on his hand was divided into two identical ones, and the one with the "brain" was now in his hand.
After all, he needs to do a lot of operations.
The process of separating this bracelet is extremely magical. It first breaks from a certain position, and then one end stretches along its tangent direction. After the length is right, it suddenly curls in the opposite direction and embeds itself, and then gently breaks inside to form a new complete ring surface.
Fang Cheng did not see the separation process clearly. The process was so natural that it seemed a little unnatural. There was no sign of breakage or breakage during the separation, as if it had fallen from some non-existent dimension.
He guessed correctly. Just now, a world with more than three spatial dimensions revealed a tiny corner of itself to humans.
Fang Cheng took advantage of this rare free time to stare at the sea in a daze. After separating from Ai Bishui, he was finally able to calm his thoughts and think carefully about what might happen in the future.
What he needed to do was actually very simple. He just needed to fly into the air, drop the electromagnetic lens in his hand, and then leave there as quickly as possible.
He learned from his half brain that the electromagnetic lens was not an electromagnet in the usual sense that humans could produce, but a "singularity" composed of magnetic monopoles.
All magnetic objects known to mankind have two poles, namely the north pole and the south pole. This is because the magnetic flux lines must be a closed loop outside the magnet. The magnetic monopoles in the singularity can be combined in any way, showing a single north pole or a single south pole or a combination of both.
If there is only one magnetic pole, then we can only assume that the other end of all magnetic flux lines are infinitely far away, just like an isolated charge, and the Maxwell equations used to describe the electromagnetic field will also be rewritten. Similar to the electric field, if this magnetic monopole can be regarded as a point, then the magnetic field strength on its surface will also be infinite.
Or at least it can reach the point where it can attract all the magnetic field lines on the earth.
The distribution of magnetic flux lines on the earth and those of any bar magnet is topologically identical, forming an external closed torus. The magnetic flux lines start from the north pole of the geomagnetic field, spread out along the surface of the earth, and finally converge smoothly at the south pole.
Fang Cheng had memorized a conclusion when he was studying for a physics competition, which was that when charged particles are deflected in a magnetic field, they will move towards the area where the magnetic flux lines are most densely distributed. The shape of the Earth's magnetic field distribution tells us that that area is the South Pole and the North Pole of the Earth, but in the opposite direction of the magnetic pole.
The sun's charged particles will pass through the atmosphere at the North and South Poles, colliding with molecules and atoms in the atmosphere and exciting their energy levels in the process. The stimulated radiation generated by this process will form a huge ring around the magnetic poles, which is the so-called northern and southern lights.
Generally speaking, the auroras at the North and South Poles are green and distributed in strips. This is because the oxygen in the high altitude emits green light when it is ionized, and the shape of the strips shows the direction of the magnetic field lines on the earth's surface.
However, if we use a magnet with only one pole to forcibly change the convergence point, as long as the magnetic field strength around it is high enough, all charged particles coming towards it will no longer be deflected, but will rush towards it along a smooth orbit and eventually rotate and converge at the gathering point of the magnetic lines of force, which is why it is called a "lens".
In fact, when Observer No. 1 deployed the storage room, he never thought that this ancient weapon would really be used again one day, except that this "person" was made of a carbon skeleton.
To use an analogy, this sight is as strange to metal creatures as it is to humans seeing a jellyfish using a slingshot to shoot fish.
Fang Cheng stared at the sea in front of him. The rolling waves near the beach were blown by the hot wind and reflected the broken light. The sky in the distance was dotted with residual clouds, which reflected a slender and straight colorful light.
The thin line started from the ocean not far from Fang Cheng's eyes and stretched to the northwest sky at a very small angle. The angle was so small that it was almost close to the water surface. Only by looking very far away could one find that it was slowly climbing up to the sky.
The air around the light was restless, with different colors dancing happily in an interlaced manner. Fang Cheng's attention was attracted by it, and he thought to himself, this thing looks a bit like the progress bar before the game starts.
At this point in time, this metaphor really has a bit of black humor.
