Not only is most of the energy in the early stages of the planet's birth being stored in the Earth's core, but also in the early stages of solidification of the planet, the hot molten material produced inside the planet will also be transferred to the Earth's core under the action of gravity and penetration effects. If it is mainly rock,
If the planet is a planet, the radioactive material accumulated near the core can usually reach millions of times the concentration on the surface. In this environment, the highly radioactive core is almost equivalent to a thermal power plant that continues to perform slow nuclear reactions, and the heat cannot be released.
, will eventually heat the earth's core into a hot liquid metal ball: under the amazing pressure and temperature, even diamond will become as soft as butter, and no matter how high the temperature is, substances here can only liquefy but not vaporize
.
The above is the normal version of the Earth's core.
Some of the Earth's core is cooled - very cold compared to the scorching core. Even planets with long lifespans are constantly evolving towards the end. The activity of the Earth's core will gradually decrease, and radioactive materials will slowly decay to
Unable to release heat, the entire planet's transition from youth to middle age is a process of cooling layer by layer from the surface to the core. When far away from the star, this cooling rate will be even faster. When a planet enters
In old age, the core will become close to the solidification point of iron metal. After peeling off its crust and mantle, you will see a dark red alloy giant ball, showing the vicissitudes of years, loneliness and coldness, and slowly dimming in the desolate space.
The downward flame in the center of the earth is the twilight candle of an old planet.
The above is the literary version of the core of the earth.
There are also some cores that take non-mainstream routes. The highly skilled demolition team threw the entire core of their planet to an unknown place, leaving behind a warm burning rock shell. The rock shell provides heat and light, and then they are on the planet.
Plant some huāhuā grass in the big hollow in the center, and then insert a theme park sign - let's temporarily name this kind of core the ** version.
"What the hell is this?" Looking at the bright underground world and the green land in front of me, I was stunned.
"What the hell is this?" Lilina was also stunned as she looked at the giant vines that were moving slightly on the green land and were countless kilometers wide.
"A smaller planet? Stuffed inside the core of the earth?" The corner of my sister's mouth twitched a little. "And the vegetation is dense. They grow too huge."
"Maybe it's because of the direction of gravity?" I let Qi Qian Yi slowly descend. "The gravity of the green core below is one thousandth that of the earth's surface, and the surrounding mantle almost offsets the gravitational pull in every direction."
"Maybe." Sandora said noncommittally. She probably felt that the huāhuā grass growing in the center of the earth was not a problem worthy of attention.
It took us a long time to pass through the mantle. On the one hand, it was because the 700 billion slowed down its cruising speed, and on the other hand, the alloy tunnel was not straight: it led to the center of the earth along a gentle parabola.
It seems that some giant facilities buried deep in the earth's mantle have been bypassed. The radar shows that those bypassed giant facilities have extremely high energy reactions. Perhaps they are the green star's psionic energy furnaces. The ones that passed through the last spherical shell barrier
At that time, I thought that I was about to enter a sea of fire. Under normal circumstances, the core of the earth should be a scorching purgatory with molten iron flowing across it. But in fact, the sea of fire did appear, but it was behind us: the center of the earth was completely hollowed out, and the core of the earth was missing.
Only the inner spherical shell of the Earth's core (or the lowest layer of the Earth's mantle) spreads flaming rivers of magma. These rivers of magma rush on the partially cooled mantle, like the upside-down earth and upside-down rivers and lakes.
The mantle in the field of view appears black and red, indicating that its temperature is at least lower than the melting point of iron. The thick liquid rock and metal flow that still maintains high temperature flows slowly on this inverted land, like a dazzling fire dragon.
But where the core of the earth should have been, there was another scene with extremely strong contrast: a sphere with a radius of 1,500 kilometers was suspended there, as if it were another smaller planet, with no currents on its surface.
There are flows of magma and iron. There is no blazing sea of fire. On the contrary, protected by a dim barrier, this "inner star" with a radius of 1,500 kilometers is densely covered with lush green vegetation.
It is even so dense that no ground material can be seen at all.
"Ajun, to be honest, I have never seen this kind of scene in tens of millions of years." Even Sandora opened her eyes wide and said slowly in a surprised tone. "It's... beautiful and spectacular.
, it’s not technically incomprehensible. But the creativity of this project is simply... incredible.”
In the end, she described the magical star in front of her with disbelief.
700 billion slowly hovers at the gravitational balance point, 537 kilometers from the bottom of the earth's mantle and 200 kilometers from the small green planet below. Here, gravity is zero. This is a very wonderful phenomenon. For a
For a normal planet, its universal gravitation points to the center of the earth, regardless of any holes near the center of the earth. However, the instrument shows that after passing through the dividing line at the bottom of the mantle, we have entered a modified gravity environment, and part of the gravity comes from the front.
The small green planet points to the center of the earth, while the other part of the gravity is in the mantle layer on all sides. They are actually facing the opposite direction: pointing to the surface. This is definitely not a natural formation. Maybe it is some kind of safety device of the green star, which was originally built
The gravity of the earth's core is directed in two directions, forming a safe zone wide enough in the middle to prevent the magma and molten iron flowing on the mantle from falling like a waterfall on the ecological planet below, and also like an invisible cushion, allowing
The inner planet can avoid collision.
Tavel took a deep breath, released a set of twenty-two probes, and then waited quietly for information feedback. It can be seen that even a super scientist like her is a little excited at this time, in Sandora's words
Perhaps the spectacle before us can be explained technically, but the creativity and the intention of this magnificent project are unbelievable.
"There are two pieces of earth, there is no sky." Because of the loss of gravity, Qianqian simply started to float back and forth in the back half of the unusually wide carriage. She held the window and looked outside, spinning around. "One is burning with fire, and the other is burning."
There is a forest growing on it. I have seen this in my dreams when I was a child. Both floors are upside down..."
I thought about it and finally understood: She had confused the Alice in Wonderland and Journey to the West scenes of the Flame Mountain. Of course, it was also possible that she had mixed up the Demon Altar Fighter and the Third New Tokyo...
Now there is no concept of up and down in this place. The bottom layer of the mantle is equivalent to the sky for the little green planet, but when viewed from another direction, it is a blazing earth. However, out of habit, we still regard the previous one as
An "inner star" with a radius smaller than the moon is seen below. Tavel completed a preliminary assessment of the environment here: "The maximum temperature of the mantle layer above is only about 3,000 degrees Celsius, and the minimum temperature is 700 degrees Celsius, which is very uncomfortable.
On average, there may be an energy system still regulating the temperature environment in the core of a green star. The green core is a medium-density body composed of soil and rock. The vegetation on the surface is confusing: so many plants, in
There is a life response displayed on the device, which is too abnormal."
"Then the entire small planet is a living organism?" Sandora showed an interested expression. "Let's go down and take a look. Tavel, let your assistant stay at the gravitational balance point for the time being and continue to observe this geocentric celestial body.
I always feel that this has something to do with the dormant chambers in the mantle."
A team of scientists opened a temporary working platform at the gravitational balance point. It was a triangular floating island shrouded in a psionic shield. We rode the 700 billion and slowly descended. The operation process was very careful because Tavel was afraid of
We will destroy the little green planet ahead.
"The center of the earth is filled with hot air of thousands of degrees." Tavel pointed to the inner star. There was a dim barrier covering it more than ten kilometers high outside. "This barrier protects the ecosystem inside. You'd better
First turn off the psionic energy shield of the aircraft. The barrier outside the target seems to have little energy left, and the psionic energy may punch a big hole in it. This is theoretically true."
I could have guessed what she said later even if she didn't say it: the fragile plants on that star would be wiped out in a fire, and I'm afraid they wouldn't even be used for a few minutes.
700 billion closed the shield, relying only on the armor layer and the airtight force field to resist the thousands of degrees of high temperature outside: but this is nothing to the transportation vehicles made by the empire. When passing through that fragile shield, everyone
I couldn't help but feel nervous. I was prepared to immediately activate my abilities to plug the loopholes once the situation got out of control. Fortunately, everything went smoothly. The dim shield above the small green planet withstood the test, and it only flickered partially.
Just for a moment.
We landed slowly in a dense virgin jungle, and the scorching shell of 700 billion scorched some plants. But overall, this landing was quite environmentally friendly.
"It is very similar to the environment of New Eden 4, with a slightly higher temperature. The air contains oxygen, but it is not suitable for human habitation: the oxygen content is too low, and the gravity is not enough."
Sandora jumped on the spot as she spoke, "There is artificial gravity under the shield, but the intensity of gravity is only a little bit greater than the surface of the moon. If this is not intentional, the artificial gravity system here needs a major overhaul."
"I hope it's not the latter," Tavel muttered, taking out two sophisticated hexagonal devices. I felt more and more like she was like a Doraemon, always taking out a bunch of high-tech from her pocket, "Change it."
Two life detectors, the results are still the same, there is only one living thing here, which is the planet under our feet: if it can be regarded as a planet."
Of course it's a planet. Anyway, I don't believe that under normal circumstances, the core of the earth can shrink and leave the mantle for nearly a thousand kilometers, then cool down, grow grass on it, and finally have its own rotation period and angle: this is the 700 billion scan just now
Conclusion after that. I feel a little lucky now. The system composed of Green Star and its "star within the star" seems to have a self-protection device to ensure that it is mutually stable after being dragged by the Emperor and transferred to a world.
Otherwise, this smaller Green Star will definitely crash into the mantle of the Earth. However, this system is not unexpected. After all, the Green Star was originally capable of traveling across the world, but now it only has a scrapped super-world engine. For this engine
The prepared safety lock does not necessarily have to be scrapped, right?
Weak gravity, unbelievably lush primitive jungles, and huge plants. Walking in such a place, we can jump more than ten meters into the air with just a jump. It feels like walking in Alice's dream world.
After walking past a flower that I estimated was at least three stories high, I felt that I suddenly understood what Dingdang's normal perspective was like.
"I think there is a sense of incongruity here." Sandora didn't like the feeling of walking through the forest and trees in microgravity, so she simply floated in the air and whispered, "Some things are unreal. These huge things on the ground are
The vines are fine, but... wait."
Sandora suddenly stopped, and then a golden halo slowly circulated in her hair. She felt the surrounding environment and nodded: "So that's it, I was negligent."
As she spoke, she casually pressed down on a gigantic shrub. With just a slight impact of her mental power, the sturdy-looking plant turned into scattered green light spots in the blink of an eye.
"It's a mass projection." Tavel stretched out his hand to catch these light spots, watching them slowly reorganize into a colorful bird - half the size of Pandora. The current Tavel is a mass projection, I have never used it.
It’s hard to imagine what kind of feelings a body in this form would have. But I’ve heard about the characteristics of this technology. It can create a mirror image that is exactly the same as the original body. The mirror image has an entity and can be the same as an ordinary body.
It affects the material world and can even simulate the physical strength of the body. However, mass projection cannot carry the body's special abilities, such as the large number of scanning components in the Xiling Apostle's body: the mass projection is just a convenient terminal for work, it is tangible and has no spirit.
Therefore, Tavel needed to use various external equipment (scanners, probes, etc.) when working with mass projection, and the functions of these equipment were already possessed by her body. Therefore, she was not able to discover it at the first time.
The environment here is abnormal. It was Sandora who discovered these secrets. "It is much less stable than the projection produced by the Empire's technology, but the visual effect is more realistic. If you only use conventional senses, you can't tell the authenticity. But with any kind of
Energy radar can detect the unreality of these projections: their energy response is single and there is no sign of life."
"In other words, only the vines under our feet are real, and everything else is an illusion."
The elder sister nodded and said, she didn't like the feeling of being tripped by vines while being light here, so she floated in the air side by side with Sandora and moved forward in a suspended manner.
Qian Qian didn't know what she thought of again. She climbed to the top of a plant and shouted loudly: "Is there anyone? Is there anyone who can answer me?"
I quickly went up and pulled down this girl who was having seizures at any time: "What are you yelling about?"
"Don't say anything. She's not yelling nonsense." Shandora smiled and floated over. "I feel that something just came out of the vines in the distance, and it is approaching here."
We stopped in surprise and waited patiently for a while. After a while, a huge clump of leaves not far away suddenly rustled, and then in everyone's surprised eyes, a man with pointed ears and a head on his back appeared.
A little girl carrying a hunting bow emerged from behind the leaves, her bright light green eyes looking here in shock.
The little girl was wearing light and close-fitting clothing that was suitable for walking in the forest. The white clothing was decorated with green embroidery on the edges. It was not clear what material the clothing was made of. It was a bit close to leather, but it looked extremely soft. She wore a pair of leather ropes under her feet.
The little boots were tied up, and the boots were still stained with mud. The girl looked about twelve or thirteen years old, with a slender figure but not giving off the impression of being thin. She had short green hair, and a pair of pointed ears peeking out from the short hair.
She stood out. She had small and delicate facial features, fair skin, and had similar facial features to the girl in the dormant cabin we found "above" before. Finally, my eyes fell on the other party's hunting bow - it was obviously
A toy. First of all, its size is completely designed according to the figure of a twelve-year-old girl. It is probably not very powerful when it is full. Secondly, there is a small straw doll tied under it. This thing does not look like a weapon.
There are some things, and of course the most important feature is the quiver that is carried cross-body with the hunting bow. The arrows in the quiver are placed in a mess, and some of the arrows are pointing upward. I can swear on my integrity that this kind of arrow uses a leather stopper as an arrow.
Bows and arrows are strictly for use by minors under the age of fifteen...
"Quality projection."
Shandora said in the spiritual link, I understand: the little girl in front of me turns out to be not real.
"Ah! Intruder!"
The little girl looked at each other for five or six seconds before she suddenly reacted. Then she awkwardly took off the small hunting bow on her back, spent five seconds bending the bow to set the arrow, and then hurriedly turned the arrow around.
We then aimed for a long time, and after drawing the bow for a long time, we said with a cry: "Don't move, I will aim in a moment, you just wait a moment..."
Everyone: "..."
"Dingdang doesn't have to worry about his intelligence." Lin Xue turned her head and whispered.
Then an arrow with a leather stopper finally shot out of the air and hit Lin Xue's forehead with a "pia" sound and stuck there. The eldest lady's face stiffened, and I turned my head and popped out.
:You can’t tell, but this silly little girl is quite accurate. She can hit her head with one arrow. This is it.
"Ah, I'm sorry, I wanted to shoot that man's knee, but I missed..." The panicked voice of the little girl came from the front.
I:"……"
The circle of people burst into pieces!
Lin Xue pulled out the harmless toy arrow on his forehead and threw it back to the little girl. Then he stepped forward. The little girl backed away step by step with a nervous look on her face: "Don't come here! Intruder! Here.
This is a forbidden area! No one can come in! If you go out, the patriarch will be angry! Come out quickly... Wow!"
The little girl stepped on the air and fell down from the vines, sitting on the ground and crying loudly.
Shandora frowned, her tone full of helplessness: "Arjun, if someone uses mass projection just to make a joke on us, then this is really bad."
"There is no hostility, and there is no danger." Lin Xue shook her head and said, and then she and her sister ran forward to help the little girl who was hurt by the fall. I felt a little inconsistent, so after thinking for a while, I said to Sandora:
"Oh, by the way, will the mass projection hurt if it falls?"
"Well, in theory, mass projection will ignore too strong physical sensations." Sandora shrugged. "But the mass projection here uses a different technology from the empire, so it's not sure. Maybe they put the real feeling
Integrated into the projection, although I think this is a stupid idea."
After a period of confusion, Sister-sama still managed to calm down the messy little girl. Maybe it was the effect of some naughty child controlling the aura again. The little girl was brought to us, with tears still in the corners of her eyes, and she glanced at us timidly.
: "You don't eat people, do you?"
I...I'll go! What on earth did we pick up and come back, and why are there such strange creatures inside!
