MC-7b is an exoplanet in the MC-7 star system, located at a distance of about 3 light-years from the solar system. It is a planet unique in its position, climate and physicochemical properties, and is the only planet in the universe (except for the Earth) where intelligent life has been officially found. It was discovered in 2037 as part of the MC project to discover new planets and search for possible places for colonization or exploration in connection with the advent of ultra-high-speed transportation technologies; it was the first planet discovered in the MC-7 system. In 2043-2053, the world's first interstellar journey using a spacecraft powered by antimatter and nuclear energy, organized by the United Nations, took place on this planet; during the trip, the unique structure and ecosystem of the planet were studied, and many new species were discovered, including several intelligent and humanoid species. The planet has a surface area about 7 times larger than Earth's, and has a similar climate, temperature and distribution of substances in the atmosphere, hydrosphere and lithosphere.

Geography[]
The planet has 7 continents and 7 oceans: 1 supercontinent, 3 mostly in the northern hemisphere and 3 mostly in the southern hemisphere; the oceans are between the continents. The supercontinent is called Ardoné in the vilagerá language (the language of the MC-7b-V species “vilagé”) and Artún in the language of the tall black humanoids, and its area is approximately equal to the area of the entire surface of the earth; the continent stretches from the north pole and almost reaches the south pole, occupying all available climate zones and having all possible biomes on this planet. The largest city on the planet, city №1, is located on the supercontinent, with a population of about 70 million representatives of local intelligent species. The other continents have names (in the vilagerá language, in descending order of size): Simé, Hemhé, Vahdoné, Taharé, Himdoné, Ovagé. Oceans do not have names, but have numerical identifiers depending on the area (in descending order 1, 2, 3, 4, 5, 6, 7). The planet has rivers, seas, lakes, groundwater, mineral water, and rarely geysers. As on Earth, MC-7b has a plain and mountainous landscape, but the mountains rarely exceed 1 kilometer in height.
Geological structure[]
MC-7b has a lower density than the Earth, as the mass is not distributed evenly across the planet. The unique geological structure of MC-7b is that it does not have a mantle in the classical sense, and under the crust there is a so-called multi-pocket shell, consisting of different pockets formed by different substances and separated by solid rock, a mixture of rocky stones and other strong substances. The thickness of the crust varies, it can reach from 1 to 50 kilometers, and unlike the Earth's crust, it is saturated with a large number of minerals and resources - for example, iron is found in almost every square kilometer and very high in different places; diamonds can also be found frequently, but deeper. In the crust of the MC-7b, you can find all the substances known on Earth in large quantities (the most common are coal, iron, copper, manganese, oil and gas, diamonds, diorite, gold, platinum, uranium, lazulite, radium, and others), as well as new resources unknown on Earth, such as C(31)U(31)En(38) and many others. At the same time, these resources are so abundant that, for example, professional miners fron Earth can easily extract 7 cubic meters of diamonds on MC-7b in a day, and the metal deposits are so large that they can be separated from the stones by simple heating. The crust of MC-7b does not have classical tectonic structures, such as tectonic plates or platforms, because there are no underground forces to form them (due to the absence of a mantle), and therefore there are no earthquakes or volcanoes there. That is why the mountains do not exceed 1 kilometer in height on MC-7b, as they are formed exclusively through the Coriolis force and biological factors, and in general, most of the surface does not depart much from sea level. However, due to the presence of lava pockets in certain places, there are certain “mini-volcanoes” and lava lakes.
There are many caves of different widths and lengths in the crust, often intersecting with each other; there are often 1 to 3 cave entrances per square kilometer, with cave radius varying from 2 to 7 meters most often. The resources described above can best be found through caves; caves may contain underground water streams, underground water and lava lakes. There may also be caves under the surface of lakes, seas, and oceans; in the waters there are rocks familiar to the Earth, such as sand or rock salt.
Below the crust of MC-7b is the bedrock shell, which separates the crust from the pocket zone. This crust is extremely thin (about 1-2 kilometers thick) but extremely dense and strong. It is made of a material called bedrock, which does not exist on Earth but exists on MC-7b as a barrier between the three zones of the planet - the crust, the pocket zone, and the core. Bedrock is currently the strongest material ever found by humans in the universe, it simply cannot be destroyed by modern Earth technologies, and it far exceeds diamond and other substances in the strength of molecular bonds. There are two bedrock shells on MC-7b - between the crust and the pocket shell and between the pocket shell and the core. To pierce these shells and extract the bedrock, the MC-7b-V and MC-7b-E intelligent biological species use laser and molecular technologies that do not exist on Earth. They use bedrock to make armor for military personnel and for spacecraft.
Under the first bedrock layer is the multi-pocket MC-7b shell. It is unique in that it has several types of pockets - compartments with different internal fillings with different substances. The main types of pockets are: air (usually very small in volume, about 10 square meters), air-stone (the largest possible in volume, several hundred kilometers long, unique for its flying stone islands levitating under the influence of homogeneous magnetic induction lines generated by the bedrock), lava (slightly smaller than air-stone, completely filled with hot lava), organic (medium in volume, filled with oil, gas and other organic waste, have bacteria-like organisms), water (filled with water and water vapor, small in volume) and other unique/combined ones. The temperature in pockets depends on their contents, proximity to the core and neighboring pockets. For example, air-rock pockets occupy about 37% of the total multi-pocketed shell, are close to the crust, and have a slightly higher temperature than the surface (about 25-30°C), and it is there, on the flying islands, that the homeland of tall black humanoids (MC-7b-E) is located. Lava pockets also occupy about 35% of the area. The boundaries between the pockets are formed by stone and obsidian (especially for lava pockets), and the pockets themselves are randomly located, have chaotic positions and neighbors, although there is a tendency for air and air-stone pockets to be closer to the planet's surface and lava pockets to be closer to the core, although this does not always work. If you imagine cutting the MC-7b in diameter, you will see many (about 5000) randomly located pockets with different contents and shapes between the bark and the core, which look like different and uneven honeycombs.
Beneath the multi-pocketed shell is the second bedrock shell, which covers the third part of the planet - the core. The core has an average radius of about 7,000 kilometers and consists of two sub-shells, the surface and the central one. The surface surface has a temperature close to that of the air-rock pockets, slightly higher, from 30°C to 40°C. This is due to the fact that this part of the core is a full-fledged ecosystem where bacteria, fungi, and animals live (no plants), and they influence the temperature with their organic matter, as well as due to the presence of air pockets in certain places near the core. Previously, this part of the core had a temperature of about 100°, but portals from the planet's surface created by the MC-7b-V species several thousand years ago brought coolness and led to the cooling of the core and an increase in temperature on the planet's surface. This led to a change in the chemical composition of the local air (increased oxygen and nitrogen) and to ecological changes with extinction, adaptation to new conditions, and "relocation" of surface species to the core. But it was this that actually created a rich self-regulating ecosystem in the core and ensured the possibility of the existence of intelligence there, which happened when the intelligent species MC-7b-P, which is the closest mentally to humans, emerged. The first part of the core has lava lakes and special soil. However, there is also another part of the core that is lower and in the center. It's surrounded by solid obsidian and filled with hot lava inside, and is essentially what the Earth's core is believed to be. Only a few bacteria live there.
Climate[]
Despite its differences from Earth, the MC-7b does not have the same diverse climate as Earth, even though it rotates faster around its star and has a greater axis angle. On the planet's surface, representatives of the MC-7b-V and MC-7b-E species clearly distinguish only three permanent climate types: cold, temperate and warm, and one mixed (variable) type. On this planet, the climate is influenced not only by the star but also by the type of underground pocket, the presence of lava and water underground. For example, if there is a lava pocket underground, the temperature will be higher, and if there is a water pocket, the temperature will be lower. In general, cold climates have temperatures below 10°C, temperate climates have temperatures between 10°C and 30°C, hot climates have temperatures above 30°C, and mixed climates vary in temperature (from -30°C to 50°C) depending on the planet's location relative to the star, i.e., like the variable weather of the temperate climate zone on earth. The latitudinal zonation of these climates on MC-7b is similar to that on Earth (warm closer to the equator, cold closer to the poles, and temperate and mixed between them), but this zonation does not coincide in the case of lava or ice water underground pockets near this surface in the multi-pocket shell of the planet and with a thin crustal layer, since in this case, respectively, warm and cold conditions can occur at atypical latitudes. Cold conditions are characterized by cold temperatures and snowfall, warm conditions by hot temperatures and rains, and temperate conditions by a constant temperature approximately at the level of late spring of the Earth's temperate continental temperate climate (no analogues on Earth to this climate).
The mixed climate on MC-7b is analogous to what is called a temperate climate on Earth, i.e., the change of seasons depending on the location of the planet relative to its own star (MC-7). As on Earth, there are four seasons on this planet, analogous to winter, spring, summer, and fall, which have similar weather conditions of temperature and climate to Earth's. However, these seasons are shorter than Earth's because MC-7b orbits its star faster. Mixed climates have a narrower distribution on MC-7b compared to Earth, because where Earth has its southern temperate mixed and maritime temperate mixed regions, MC-7b has its temperate climate (the one with a constant temperature between 10°C and 30°C). In addition to the temperature classification, the locals on MC-7b distinguish a classification based on precipitation and moisture (wet, temperate and dry zones), which is similar to Earth and depends on the movement of air masses. In general, in addition to astronomy and geology, the planet's climate is strongly influenced by the effects of the Coriolis force, such as winds and water currents, and more so than on Earth (it is the influence of warm currents from temperature-saturated sub-oceanic lava pockets that caused the emergence of a temperate climate with a constant temperature, which does not exist on Earth). In general, in many ways, the planet's climate is actually similar to Earth's, but Earth scientists use alien classification models for this planet because of peculiarities such as the influence of geological structure, which, for example, sometimes leads to the neighborhood of deserts and glaciers.
Chemical composition of the atmosphere[]
The chemical composition of the MC-7b atmosphere is similar to Earth's, as it has almost the same distribution of gases in the atmosphere layers. Just like on Earth, the atmosphere on MC-7b can be divided into several layers based on composition, density, and function. This planet has an ozone layer that consists almost entirely of ozone, but unlike Earth, this planet has a larger ozone layer and a higher density, which leads to a lower greenhouse effect and greater protection from solar radiation (which is important because the planet is closer to its own star than Earth and this star is larger than the Sun, which in turn compensates for the heat that comes from the mantle on Earth, because MC-7b has no mantle). Under the ozone layer is the bulk of the air, which has a distribution of gases similar to the Earth: 67% nitrogen, 33% oxygen, 1% other gases (water vapor, argon, carbon dioxide, helium, neon, etc.). Earth-based researchers did not find any substances in the air of MC-7b that would not exist on Earth, which was confirmed by local residents. The composition of the air is considered to be one of the main reasons for the emergence of life, which in many ways resembles a copy (or rather a "parallel world") of the Earth's, with certain features (for example, arthropod-like organisms are larger due to the higher oxygen content). The air has a density almost identical to Earth's, and the pressure at sea level is about 101,310 Pascal (very close to Earth's).
Biology, ecology and biodiversity[]
When Earth scientists first arrived on MC-7b, they were so surprised that they could not believe their eyes at first, attributing what they saw to hallucinations or the effects of unknown psychoactive substances in the air; some of the more religious began to be baptized. But it was the first living organisms they saw that surprised them: trees 1 meter thick, organisms similar to Earthly pigs and cows (but disproportionate), and strange intelligent humanoid creatures whose eyes glowed in the dark (because the astronauts landed at night). As you might guess, it was not the differences from Earth that surprised the astronauts, but rather the extraordinary similarity of the organisms to Earth's, as if they had been copied or the Earth had been distorted. Even now it is impossible to say exactly how evolution led to this. In general, there are two features of MC-7b biodiversity: similarity to Earth (in some cases only indirect, and in some cases almost exact copies) and very small diversity of living organisms (for example, only about 1000 animals were counted).
Life on MC-7b, like on Earth, is carbon-based, has RNA acids, cells with identical organelles, reproduction, and ecosystem organization. However, there are some differences at the highest level of chemical organization: the organisms of this planet mostly use different (though very similar) substances for life. In general, life on MC-7b is very similar to Earth in terms of hypothetical evolution, classification, ecology, distribution, and basic chemical basis, but the main difference is the low biodiversity: Excluding quasi-organisms such as viruses or prions, only 25,737 species of living organisms have been officially described by MC-7b intelligent species (primarily MC-7b-V), of which 12,584 are microscopic unicellular or colonial prokaryotes (i.e., they are similar to Earth's bacteria and archaea, lacking a nucleus). The remaining 13,153 are eukaryotes, i.e., they have a cell nucleus, and among them there are several types of nutrition: autotrophic, heterotrophic, and mixed. As on Earth, autotrophic nutrition is represented mainly by the reaction of chlorophyll with sunlight, but there is another way of such nutrition - the photoelectric effect (the presence of mitochondria in skin cells that can knock out electrons with the help of sun photons, converting them into energy for building proteins). However, the photoelectric effect is present only in animal-like organisms and is not the main way of nutrition, but only an additional one to the heterotrophic one. For example, such nutrition exists in the intelligent species MC-7b-V and MC-7b-P.
It is not yet known how MC-7b living organisms should be classified, since it is not known whether such similarity to Earth life is the result of panspermia (common origin through space) or just a parallel evolution that has nothing to do with Earth organisms. Currently, it is officially recognized that the domains of prokaryotes and eukaryotes can be applied to these organisms because of the generally similar principle of cell construction, but whether further Earth taxa can be applied to them as kingdoms or genera is not determined, and this topic is still being debated. It is important that most of the information about the living organisms of the planet was taken from its indigenous inhabitants, namely from the MC-7b-V species, which provided information about these species, their characteristics, and the classification adopted by them. In general, this classification for eukaryotes includes what on Earth can be considered analogous to animals, plants, fungi, and protozoa, namely: mobé (animal-like organisms), logé (plant-like organisms), skalké (fungal-like organisms), and parhé (protozoa-like organisms). The main criteria for alien classification are the structure of cells and tissues, type of nutrition and reproduction, metabolism, way of life, ecological niche, and sometimes also origin (it is important to note that due to the ancient age of the ecosystem, it is difficult to determine the origin of organisms on MC-7b). Classification by nutrition: mobé - heterotrophic (possible with additional autotrophic), logé - autotrophic, skalké - only heterotrophic, parhé - only mixed (both heterotrophic and autotrophic equally).
The smallest organisms on the planet, MC-7b, belong to the mohré group, an analog of Earth's bacteria and archaea. Like their Earth counterparts, mohré have circular DNA in the form of a nucleoid, i.e. they are prokaryotes (non-nuclear). The nucleoid and the general chemical structure, lifestyle, and physiological processes of mohré are almost identical to those of prokaryotic organisms on Earth. Mohré are of two types according to their nutrition: heterotrophic and autotrophic (chlorophyllous only). The Mohré is the only MC-7b kingdom of organisms on the planet that is prokaryotic, and it is the largest kingdom on the planet (slightly less than half of all known organisms on the planet belong to this kingdom). Mohré live in all life environments of the planet (atmosphere, hydrosphere, lithosphere, pockets, core and other living organisms). These organisms are among the most similar to Earth's, some of them look almost like copies of Earth's, for example, Earth scientists have discovered a species MC-7b-KT that almost completely copies Earth's E. coli, having a similar nucleoid, almost identical chemical composition and shape (with some differences) and living in the digestive system of animal-like organisms (mobé), including intelligent representatives, and participating in digestive processes. Mohré can be either unicellular or colonial, and a total of 12,584 such species have been discovered by MC-7b intelligent species.
In addition to mohré, there is another kingdom of single-celled organisms on MC-7b, but this time eukaryotic, which is distinguished by the local intelligent species - parhé. This kingdom has a nucleus, and at the same time has both plastids with chlorophyll and digestive vacuoles, so they are both autotrophic and heterotrophic, i.e., they have a mixed type of nutrition. The closest Earth analogs of these organisms are similar metabolism protozoa, such as Euglena viridis. Parhé is the smallest MC-7b kingdom in terms of the number of species, as only 214 species of these organisms have been discovered by locals. Unlike the other MC-7b kingdoms, parhé does not show any particular similarities in RNA/DNA or structure with their Earth counterparts, but rather only in chemical processes and substances, as well as in the presence of pseudopods or ciliated mobile organelles. Parhé come in a variety of sizes, some of which can even be seen under a magnifying lens.
Another important large kingdom of eukaryotic organisms is the logé, which is analogous to Earth's plants. This kingdom, like mohré, is one of the largest similarities to Earth's analogues at the cellular (DNA, organelles, chemical structure), tissue (presence of integumentary, transport, and special tissues), and organ (presence of flowers, leaves, trunk, etc.) levels. All logé are exclusively chlorophyllous autotrophs, and occupy the place of producers in the ecological chain. Like plants on Earth, logé can be divided into herbaceous and tree species, with the analog of bushes being difficult to distinguish from a morphological point of view. However, despite the incredible resemblance to their Earthly counterparts, logé have their own morphological characteristics: large trees are characterized by trunks with a diameter of more than 1 meter, but not less, there are small trees with trunks with a diameter of 2 to 5 centimeters, but there are no trunks similar to Earth birches, for example; logé species in general differ morphologically little depending on the climate or biome, mainly the difference is in the thickness of the stem or trunk and leaf area, which is mainly due to the use of slightly different substances in metabolism; some logé grow underwater or in caves near lava lakes, and the cultivated species eaten by the locals can grow in almost any climate (the result of centuries of selection), but their diversity is not the same as on Earth. The core of the planet is completely absent of logé, and therefore it represents a unique, producerless ecosystem. A total of 4,527 logé species are known. Among the most interesting logé are the MC-7b-K species, which is unique in that it has a muscle analog based on gas heating in special tissues, a nervous system analog with tubular tissue instead of neurons, a labyrinth-like chemical regulator, and an eye analog based on specialized plastids that respond to the movement of large objects, And when these plastids "see" the movement of a large object, then through chemical reactions the organism starts moving towards this moving object, and when approaching, chemical reactions heat the TNT in specialized tissues, which explodes, and the organism throws its spores onto the object attached to the body, dying. The entire process of its "behavior" is controlled by specialized tubular tissues through a variety of chemical reactions. The organism itself will not die until it explodes, and it is the only such organism on MC-7b.
Another important kingdom of the MC-7b planet is the skalké, which are analogous to Earth's fungi. These are exclusively heterotrophic organisms that are very similar to their terrestrial counterparts in terms of cell composition (DNA, organelles, chemicals), tissues and organs (there are analogs of mycelium and fruiting body with spores), and morphology (many organs, especially fruiting bodies, resemble terrestrial ones). They reproduce through spores in fruiting bodies. However, certain features distinguish skalké from Earth's fungi, primarily their size: skalké fruiting bodies are usually about 7 meters high, and myceliums can cover areas of about 100 kilometers square, and even form their own biome, where skalké are the dominant species. This biome is unique in that it exists thanks to skalké parasites that parasitize the bodies of mobé and logé, controlling metabolism in their favor (and in the case of mobé even controlling behavior), but are in symbiosis with other skalké, and the biome itself is often an island with a forest of skalké fruiting bodies, with mobé and logé in the minority and producing nutrients for skalké. Thus, the skalké kingdom has the highest percentage of parasitic organisms. Another interesting example of a skalké species is MC-7b-SV, which is an underground species that lives close to the surface in the upper layers of the lithosphere in caves, and is a large fungal growth with many specialized organs, including sound and vibration detectors that allow it to hear mobé close by. And when an organism approaches MC-7b-SV, it emits sounds using special "screamers" that attract walking weapons - mobé captured by MC-7b-SV, which have mutated under the influence of special cells and substances in the organism's trap - elastic tissue, causing changes in the DNA of the captured organism and leading to the mobé's submission to MC-7b-SV's needs, thus it is a unique parasitism. So far, only one mutant is known - an organism similar to Earth amphibians that has "joined the service" of MC-7b-SV. The MC-7b-SV detectors work on the principle of light ion movement, the screaming is done with the help of special organs, which are magnetic membranes made of integumentary tissue with electrolysis movement, and the information is transmitted through specialized mycelial cells capable of action potential (i.e., in fact, MC-7b-SV has its own analog of the nervous system). About 3,039 species of skalké have been discovered by locals, and there aren't unicellular species among them.
And the last kingdom of organisms that the locals distinguish on the planet MC-7b are the mobé, whose analogs are Earth animals. Mobé also show an incredible resemblance to their Earth counterparts in terms of cellular structure (organelles, DNA, nucleus), metabolism, and cell division into tissues (integumentary, muscular, nervous, intermediate). Mobé are heterotrophic organisms, although some of them have an additional autotrophic source of energy through the photoelectric effect in the mitochondria of skin cells (this is typical for hairless mobé). Mobé tissues are very similar to animals: muscle is formed by bundles based on electromagnetic contraction, nervous is formed by neural structures (dendrites, axons), integumentary and intermediate are respectively formed by similar "building cells". Although there are certain differences, for example, other substances may be used in metabolism, and some mobé representatives have a cell membrane in the integumentary tissues, although functionally they differ little. There is also an incredible similarity at the level of organs: mobé are divided into "simple" (without clear organ systems) and "complex" (with organ systems), and organ systems are presented almost like Earth's: nervous, hormonal, digestive, transport systems, and others. All of them show a remarkable resemblance to the animal systems of the Earth: the presence of a brain, heart, liver, blood vessels, red blood cells, hormones, limbs and fingers, head, eyes, stomach, bones etc. The "simple" mobé include sponge-like and coral-like organisms, and the "complex" mobé include analogs of Earth mammals, birds, fish, etc. Local inhabitants of the planet divide mobé into oviparous and viviparous; and oviparous are divided into "feather-flying" (analogous to birds), "gill-water" (analogous to fish), "amphibious" (analogous to amphibians), "scale-ground" (analogous to reptiles), "articulated" (analogous to arthropods); and viviparous are divided into hermaphrodites (bisexual) and dioecious. Hermaphrodites, in turn, are divided into independent (capable of self-fertilization without a partner) and dependent (requiring a partner for reproduction). The uniqueness of MC-7b viviparous is that many of them are hermaphrodites, while dioecious (especially intelligent) often lack sexual dimorphism. Three intelligent species of the planet belong to the viviparous dioecious mobé: MC-7b-V (surface dwellers), MC-7b-E (air-rock pocket dwellers), and MC-7b-P (planet core dwellers). All of them descended from a common ancestor, and they have almost no sexual dimorphism: MC-7b-E has lost it altogether, MC-7b-V has partially retained certain external features, but not behavioral ones, and MC-7b-P has retained only certain external and behavioral features. MC-7b-V is closest to homo sapiens in terms of morphological and external features (two arms and two legs, head, eyes, nose, and mouth like humans, they are so similar that one might think that these creatures are humans in makeup), and MC-7b-P in terms of behavior (the neural structures of mobé are cut off from animals by a geometric configuration, so in general the behavior of intelligent species is very specific, but MC-7b-P are the closest to homo sapiens). In total, smart species have discovered 5,373 mobé species on their planet, and ecologically they are in the position of consumers.
