Chapter 6 The light around the starry sky suddenly changed, dimmed, and flickered, and Mike raised the flag sail and looked up, seeing that the blue light emitted by the UFO was gone. Pen, fun, pavilion www. biquge。 Only then did he understand the meaning of the blue light: it was just the bright light of an empty screen of a display screen, and the surface of the giant ball was a display screen. Now, an image appeared on the surface of the giant ball, and the image was taken from the sky, showing a person floating on the surface of the sea holding a flag sail and looking up, and that person was Mike himself. Half a minute or so, the image disappears, Mike understands what it means, and the alien just says to see himself. At this point, Mike truly felt like he was standing on the top of the world. Two rows of words appeared on the screen, all in various languages, and Mike only recognized "English" in English, "Chinese" in Chinese, and "Latin" in French, German, Japanese, and Latin, and the others were obviously the corresponding languages marked in various scripts on Earth. There's a dark box that moves quickly between words, and Mike is familiar with it. His suspicions were soon confirmed, and he discovered that the movement of the dark frame was actually controlled by his gaze! He fixed his gaze on "Esperanto", where the dark frame stopped, and he blinked, but nothing responded; It should be double-clicked, he thought, and blinked twice, the dark box flashed, and the language selection menu on the giant ball disappeared, and a large line of English totems appeared: Hello! "Hello!!" Mike waved the flag to the sky, "Can you hear me?!" "Yes, you don't have to be that loud, we can hear even a mosquito on Earth. We've learned these linguistic totems from the radio waves of your planets and the tachyon waves emitted by space probes, and we'd like to talk to you about them. "Where are you from?" A static image appears on the surface of the UFO, composed of dense black dots, which are connected by complex thin lines to form a dazzling net, which is clearly a four-dimensional three-dimensional starry sky map. Sure enough, one of the black dots glowed silver, brighter and brighter. Mike didn't understand anything, but he believed that the stereoscopic image must have been recorded and that astronomers on Earth should be able to read it. The UFO display screen has appeared with text again, and the four-dimensional star map has disappeared, but has become the background of the text, or the desktop.

We build a peak, and you climb it. Those who are fighting, the loser dies, and the brave wins?! "I love going to the top. The brave will challenge themselves! "It's not a matter of liking it or not, we have to reach the top or the brave must challenge themselves。。。。。。 The aliens apparently teleported their "ventriloquies" with their minds. "Why? Do you have a lot of dangerous peaks in your world? Mike asked, knowing that this was obviously not a topic that humanity was pressing to talk about at the moment, but he wanted to talk about it, and since everyone around him thought that the climbers were fools, he had to communicate with the aliens who claimed that he had to climb the mountain, and he had won it all for himself. Peaks are everywhere, but the way they ascend is different. Mike didn't know if it was a philosophical metaphor or a realistic description, so he could only reply stupidly: "Then you still have a lot of treacherous peaks there." "For us, we are surrounded by mountains or steep peaks, which are closed by mountains and many dangerous peaks, and we have to dig holes to reach the peaks. Mike was so confused by this that he couldn't figure out what was going on for a long time. The aliens continued: "Our world is very simple, it is a spherical space, with a radius of about 5,000 kilometers according to your length unit, a planetary system slightly larger than the Earth. All the civilizations in the bubble world are built deep underground。。。。。。 First of all, the people in the world don't need to eat with their mouths, they rely on their skin to get nutrients, so they save a lot of time, and use this time for work and rest; Secondly, they don't use their mouths to speak, and they communicate in a way similar to ventriloquism, which makes their messages extremely fast. There is no such thing as death in the bubble world, and any organ damage on their body can be repaired in the hospital after it is damaged. They had a vehicle as flat as a turtle worm, which could move as fast as electricity by burning water alone, and it was as sentient as it could not collide in rapid motion. The people who soaked in the world built comfortable homes underground, magnificent cities, and their roads passed under the ocean, so they didn't need planes at all, but they also built their own spacecraft, and their spacecraft were able to fly at 100 times faster than the speed of light in the last century. However, it is this glorious civilization that is about to face a catastrophe, and this catastrophe is brought about by this civilization. The people of the bubble world hollowed out their crust, causing the entire surface to be hollowed out, and a slight shock will cause the collapse of the surface, and the turmoil of the entire galaxy will inevitably affect every member of it, this kind of galaxy turmoil can only be triggered once in tens of billions of years, and this time it will befall the generation of the bubble world. So, they plan to migrate to other planetary systems。。。。。。 However, the vast majority of them are reluctant to leave Mother Earth, who gave birth to it and raised it; The scientific research department of the bubble world has indeed come up with ways to save this disaster, and these tricks are nothing more than support or filling. Support is to add some pillars between the ground and the "canopy" underground, to support the surface, this is a simple and easy method, although it requires billions of tall alloy steel columns, which can be done by people in the bubble world, but if even the base of the pillars - the mantle also vibrates, the supporting role of these pillars can not be played at all, and they will be buried in the ground with the civilization of the bubble world in a very short time. Another way is to fill the gap. Fill the crust hollowed out by billions of years of people who have soaked the world with a material similar to a spherical rock formation, and restore it to its original appearance. This is a cure for the root cause, but there is little hope of achieving it, and although the people of the bubble world have developed this filler and have enough capacity to produce enough of these things to fill the earth's crust, the people of the bubble world still cannot accept this method. It's not that they are reluctant to give up the civilization they have built, but that they can't live on the ground, otherwise they would have rebuilt their civilization on the surface long ago. The emerald bodies of the intelligent creatures of the world wither as soon as they come into contact with the sun. So you are the core people; Yes, 10 billion years ago, thirteen celestial bodies of different sizes were born in this planetary system, which is exactly the opposite of the orbit of the ten planets of your solar system, and the two suns rise in the west and set in their established orbits. The primordial core people of the bubble world did not know that although the spherical space they lived in had a radius of about 5,000 kilometers, this space was surrounded by rock formations, and if they walked in any direction, they would encounter a dense rock wall. The first universe model of our core man was naturally established: the primordial universe was composed of two parts, one was the spherical space in which we lived with a radius of 5,000 kilometers, and the other was the rock formation around this space, which extended infinitely in all directions. So, our world is a cavitation in this solid universe, and we call it the primordial bubble world. This theory of the universe is known as dense cosmology. Of course, this theory does not rule out the possibility that there are other cavities in the infinite rock formations, closer or farther away from our core man, which will become the motivation for future exploration. "However, it is impossible for an infinitely thick rock layer to exist, and it will collapse under gravity." We didn't know about gravity at that time, there was no gravity in the bubble world, and we lived in weightlessness. The real realization of the existence of gravity was tens of thousands of years later. "So these vacuoles are equivalent to planets in the solid universe? It's funny that your universe is the opposite of the real one in terms of density, like a negative of the real universe. "The real universe? This is a very shallow statement, and it can only be said to be the three-dimensional three-dimensional space of the universe as it is now known. You don't know what the real universe looks like, in the words of you earthlings, there is heaven outside the sky。。。。。。 the Milky Way, extragalactic superintelligent star cloud systems and the so far unrecognizable broader four-dimensional space\multi-dimensional cosmic curved phase space; In a word, we don't know if there are other starry universes outside the universe。。。。。。 It's so profound! "Is there sun, air, and water?" No, none of us need to. There are only solids in our core world, no gases and liquids. "How can there be life without gas and liquid?" You may not know that three million years ago, intelligent beings in the mantle lived in the dark world all year round, and their blood was green; Once exposed to sunlight for a long time, its life can only be coagulated. On the contrary, we are mechanical beings, our muscles and bones are made of metal, our brains are ultra-highly integrated chips, electric currents and magnetic fields are our blood, and we feed on the radioactive rocks in the earth's core and live on the energy it provides. No one made us, it all evolved naturally, from the simplest single-celled machinery, from the PN junction that formed by chance on a rock under the action of radioactivity. Our primitive ancestors first discovered and used electromagnetic fields, and as for the core flame in your sense, it seems that it was discovered in the Nine Layers of Hell. "It must be dark in there." There are some bright lights, which are produced by radioactive materials on the inner wall of the earth's core, and the inner wall is our sky. The light was weak and moved erratically across the rock face, but we also evolved eyes from this. The core is weightless, and our cities are suspended in that dimly lit space, about the size of your city, and from a distance, like glowing clouds. Silicon lifeforms and mechanical life have evolved much longer than your carbon-based life, but we have all come to the same point and have all come to the day when we think about the universe. "However, this universe is really aggrieved." Hold...... It's a new word. Therefore, our yearning for the vast space is stronger than yours, as early as the ancient times of the bubble world, the exploration into the depths of the rock formation began, and the explorers dug tunnels in the rock formations to try to discover other cavities in the solid universe. There are many strange myths about these imaginary bubbles, and the fantasies of other bubbles in the distance constitute the main body of bubble world literature. But this exploration was initially forbidden, and violators were to be put to death. "Is it forbidden by the church?" No, there is no church, and a civilization that cannot see the sun and the stars cannot produce religion. The Senate forbade tunneling for very practical reasons: we don't have your near-infinite space, and you humans can indulge in the sun, the air, the rain, the earth, and the sea; And our living space is only 5000 kilometers. The crushed rock excavated by the tunnel will accumulate in the core, and since it is believed that there are infinitely thick rock formations, then the tunnel may be dug for a long time, and the final excavated crushed rock will fill the core space! In other words, the spherical space of the Earth's core is transformed into a long tunnel space. "There seems to be a solution: put the excavated rock into the tunnel that has been dug at the back, leaving only room for the explorers." Later expeditions did just that, and the space where the explorers lived was actually a small moving bubble, which we called a bubble boat. But even so, there is still a pile of rubble equivalent to the space of the expedition ship into the core space, and only when the expedition ship returns can this pile of rubble be refilled back into the rock wall, if the expedition ship has no return, then the core space occupied by this small pile of rubble cannot be recovered, which is equivalent to this small piece of space stolen by the expedition ship, so the explorers are also called space thieves. For that small world, such a small space is also precious, and for a long time, with the departure of one expedition ship after another, the space occupied is also huge. So antimatter ship expeditions were also forbidden in ancient times. At the same time, antimatter ship expeditions are a very difficult activity, with a number of diggers and a navigator in a typical expedition ship, and there were no TBMs at that time, and only by digging with diggers (equivalent to the oarsmen on your ship) using simple tools to keep digging, the expedition ship could move at an extremely slow pace through the rock formations. Working like a machine in a small hollow that can barely fit in, chasing a slim hope in claustrophobia, undoubtedly requires great mental strength. Since the return of the expedition ship is usually along the path that has been dug loose, it is relatively easy, but the gambler's desire to find often drives the explorers to cross the safe return point and continue on, at which point the return stamina and supplies are not enough, and the antimatter ship will run aground on the way back, becoming the explorer's grave. Despite this, the exploration of the bubble world to the outside world, although small, has never stopped.
