We are here with a new episode as the PASO Video Space Team. The rare world hypothesis, planetary science, astronomy and astrobiology say that the origin of life and the reproduction like in the world, the biological complexity of multicellular organisms, astrophysical and geological situations and events can be possible with an unexpected combination. The same hypothesis continues that there should be very few extraterrestrial life forms. In this perspective, the world is a typical rocky planet and is located in an exceptional region. According to the principle of ordinariness, the universe can be full of many complex lives. Wart and Bromley claim the opposite. In the planetary systems, the planets located in galactic regions can provide the necessary conditions for starting complex life, and there are very rare regions in the solar system and the Milky Way galaxy. The rare world hypothesis says that there should be a number of coincidental events For example, a galactic habitable region, a habitable habitatable region, a star in the center, a rocky planet with suitable dimensions, a protective gas giant and a large natural satellite in Jupiter dimensions. Moreover, it needs a magnetic field, tectonic plates, lithosphere, atmosphere and oceans. When these conditions are met, the formation of eukaryotic cells, reproduction and plant, fungi and simple animal organisms may be possible. The development of human intelligence may require many more conditions. 66 million years ago, in this universe that destroyed dinosaurs, which were the dominant species of the Umur people, it was not very likely that these conditions existed. In order for a small rocky planet to support complex life, it is necessary for many different situations to encounter each other in a narrow space. If the universe is wide enough to have such planets, but if there are such planets, they would probably be thousands of years away from each other. Such a distance makes it almost impossible for the smart life forms to communicate with each other. This is known as Fermi Paradox. If the smart life forms are so widespread, why are they not visible? The rare world hypothesis says that the known part of the universe, including the large planets in our own galaxy, is inaccessible for complex life. Ward and Brownlee called these types of areas dead areas. Moving away from the galactic center determines this area. As the distance increases, the metallicity of the stars decreases. Metals are necessary for the formation of rocky planets. In astronomy, all elements except hydrogen and helium remain. The X-ray and gamma-ray radiation from the black hole in the galactic center reduces the intensity of the radiation coming close to the neutron stars. Moving away from the galactic center determines this area. As the distance increases, the metallicity of the stars decreases. Metals are necessary for the formation of rocky planets. In astronomy, all elements except hydrogen and helium remain. The X-ray and gamma-ray radiation from the black hole in the galactic center reduces the intensity of the radiation coming close to the neutron stars. Radiation is dangerous for the formation of complex life. The rare world hypothesis says that in the early universe, the star density is high in galactic regions and supernovas are widespread, so the situation is inaccessible for the formation of complex life. The gravitational indecision on the planets increases as the star density decreases. Therefore, planets away from the galactic center may fail to intensify and large rocky planets cannot be formed. Therefore, a large enough effect can destroy all life on the planet. As it approaches the inner limit of the outer limit of the galaxy, the probability of life occurring increases first and then decreases. Therefore, the galactic region may be limited by housing life in the region between the outer and inner limits in the form of a circle. A planet system must be able to provide the necessary conditions for the continuity of complex life while having the conditions to support the formation of complex life for a certain period of time. If the orbit of the central star is elliptical or hyperbolic, some spirals pass through the arms. However, if this orbit is a perfect circle, the rotational speed of the spirals on the arms will be the same. In this case, the star will be dragged to the area of ​​the spirals. Therefore, the rare world hypothesis says that if a star is going to form a living galaxy, the galaxy of the star should have almost a circular orbit. Synchronization required for the visual speed of the star in the center can only occur in the arms, which extend from the galactic center to a very narrow area. This region is called the galactic habitable region. Based on the estimated number of stars in the galaxy, it is thought that the total number is around 20-40 billion. It is thought that about 5% of the stars on the Milky Way are located in this region. About 77% of the observed galaxies are spiral galaxies. And 2 out of 3 of the spiral galaxies act like a multi-armed spiral galaxy like the Milky Way. According to the rare world hypothesis, what makes our galaxy different is a tranquility that exists in 7% of its own kind. Even in this case, this is a number that corresponds to more than 200 billion galaxies in the known universe. The reason why our galaxy is unique in the world hypothesis is that it has experienced much less collision than other galaxies in the past 10 billion years. This peaceful past has made our galaxy a much more favorable place for a complex life. The degree of activity of the black hole in the center of the Milky Way may have been an important reason. Too many or too few events make life more rare. The black hole in the Milky Way exists in the most proper way possible. It is a completely perfect circle around the Milky Way due to the orbit of the Sun. The rare world hypothesis says that the Sun is also rare, but according to the calculations of astronomer Karen Masterson, this period of time is approximately 100 million years. Global examples argue that for a complex life to exist, water must be in liquid form and therefore the distance of the center star must be at a suitable value. This creates the essence of the life area or Goldilocks principle. The life area creates a circle around the center star. If the appearance of a planet is too close or too far to the Sun, the surface temperature of the planet is not suitable for water to be in liquid form. The life area shows a change according to the type and age of the center star. For a developed life, the star must have a certain degree of stability. The life area of a star that follows its order decreases with time until the star returns to the white dwarf, and eventually completely disappears. The life area is closely related to the Sera effect. Even the atmosphere of the Earth contains a water vapor between 0% and 4%. In recent times, the increase in CO2 amount has increased the temperature of the Earth by about 40 degrees. Terrestrial planets must be in the life area for life to occur. Although the life areas of hot stars such as Sirius and Vega are wide, planets that are too close to the star cannot survive even if they are in a habitable area. Hot stars emit much more ultraviolet light and ionize the atmosphere. As stated above, hot stars can turn into red dwarfs without allowing a developed life form to form on other planets. These assumptions do not cover the F6 type of very heavy and powerful stars. These types of stars are capable of animal life. Small red dwarfs have smaller habitable areas. The same face of the planets constantly looks at the star. Therefore, this part becomes very hot and the other surface becomes very cold. There is a risk of ionizing the atmosphere in the sun's radiation, and therefore it is opposed to the formation of a complex life. Therefore, according to the rare world hypothesis, life does not exist in such systems and in the systems of stars in the F6K1 class. The stars in the G type are rare. The F type stars are very hot. The K type stars are very cold. The G type stars are among them. Nine percent of the planets that use hydrogen as fuel on the Milky Way have this feature. Stars with life, such as red dwarfs and white dwarfs, have very low chances of supporting life. Red dwarfs are common in global galaxies and elliptical galaxies. White dwarfs are stars that have already passed the red dwarf phase and are very close to death. Stars that turn into red dwarfs are wide enough to take their habitable areas into their interior or heat enough to heat this area to very high temperatures. Therefore, planets that are much farther away from the previous habitable area may be able to support life. The change in the life of the star hinders life to a large extent. Even if a sudden descent is very short, it can freeze every area on the planet in the orbit with water. In fact, a great rise can evaporate everything. And this causes the greenhouse effect. This effect may prevent the oceans from re-forming. Without a complex chemistry, it is not known whether life will exist or not. Such a chemistry requires metals. Apart from hydrogen and helium, other elements, metals, are necessary for life to form. The only known way for such metals to form is a supernova explosion. The low metal ratio is a characteristic of the early universe. Knotted clusters and other stars have also formed in the early stages of the universe. The stars, which have a large amount of metal, were available to support complex life. It is thought that these places are in the outer arms of the galaxies. At the same time, the radiation rate in these areas should be low. The rare world hypothesis says that the planetary systems should be in a sequence similar to the solar system in order to support a complex life. The inner planets should be small and rocky, the outer planets should be large and gaseous. Without the protection of these gas masses, their gravity is quite strong. The number of collisions with asteroids will be much higher. And there will be a greater loss of mass. In addition, the sequence of the solar system is not only rare. It is also the most suitable sequence. Because large-mass and gravity gas giants can prevent asteroids from hitting small rocky planets in the system. The rare world hypothesis says that large gas masses should not be too close to planets where life develops as long as there is no satellite. A position close to gas giants can reverse the possibility of life by playing with the area where it can live or live. Newton's dynamics creates chaotic planetary orbits for systems that place large planets in high outer centers. The continuous fixed orbit rule excludes the star systems that contain large planets close to the host star. It is believed that hot Jupiters exist far away in the host stars. According to the rare world hypothesis, a planetary planet is necessary for life to form. Large gas giants cannot support complex life because they do not have such a surface. A planet of very small dimensions cannot hold its atmosphere with its own gravitational pull. Therefore, the surface temperature changes a lot. And the average temperature shows constant variability. It is impossible for oceans to form that will exist for a long time. A small planet also has a smooth surface. It has large mountains and very deep canyons. The core cools very quickly. Therefore, the plate tectonics are either too long for life to form or never occur. A very large planet holds much of its atmosphere with its own gravitational pull and becomes like Venus. Although Venus has very similar dimensions to Earth, the atmospheric pressure is 92 times higher than that of Earth. The surface temperature of Venus is 735 Kelvin. This temperature makes Venus the hottest planet in the solar system. Although the atmosphere of the early period of the world is similar to Venus, it has lost its huge impact effect. The rare world hypothesis says that the plate tectonics and magnetic fields are necessary for a complex life of ordinary creatures. Ward-Weber-Only says that the carbon cycle of biological diversity, the values of global temperature and the magnetic field need plate tectonics for a complex life of the world. Ward-Weber-Only claims that even the existence of ordinary mountains does not exist elsewhere in the solar system is a direct proof of tectonic movements. And this supports life. Plate tectonics depend on the content of the chemicals used during radioactive decay. Less dense rocks need to form to swim on the mafic rocks. Scientists say that the complex life of the world is supported by the tectonic movements of the plates by providing a chemical cycle. As a result of the extraction of plate tectonics and continents, different continents have been formed and these continents have been given the opportunity to form many ecosystems. This situation has allowed the formation of many species and thus a strong defense against the possibility of extinction has been obtained. The competition between species change and later continents of the world can be given as an example of the Great American Migration. The Moon is an extraordinary situation in the system. Because the other galactic planets in the solar system, i.e. Mercury and Venus, do not have a satellite. Or they have satellites that they obtain by capturing small asteroids like Mars. The theory of gravity says that the Moon is formed as a result of a collision with an object in the size of Mars. Thea and the world have collided. Thea is an assumed planet that collided with the world 4.5 billion years ago. As a result of the collision, the Thea planet was shattered, some of it was scattered over the world, and the rest of it formed the Moon. This theory explains the magnitude, density and geological differences of the Moon's core. It is thought to be the size of Mars. According to some ancient planetary theorists, it has not completely disappeared, and it still exists at Lagrange points 4 and 5. This collision has also gained the magnitude of the world and provided the speed of rotation. This sudden rotation caused the temperature to change and caused photosynthesis. The rare world hypothesis says that the speed of rotation should not be too large or too small according to the planet in the orbit. A planet with a large magnitude of magnitude will feel a lot of seasonal changes. And this is not suitable for a complex life. If a planet does not have a slow or negative magnitude, it will be deprived of the events that the climate change will trigger. From this point of view, the magnitude of the world is identified as exactly ideal. At the same time, the gravitational pull of the satellite affects the magnitude of the planet. Without the effects of this magnitude and magnitude, it is almost impossible to create a complex life on the planet. If the world did not have the Moon, the ocean tensions caused by the gravitational pull of the Sun could be only half of the ocean tensions caused by the Moon. A large satellite creates large tensions, and this may be necessary for the formation of a complex life. A large satellite also increases the possibility of plate tectonics thanks to tensions. The same effect that creates the Moon may have started the tectonic movements of the plates. If a giant collision is the only condition to have a large satellite, there must be any planet in the area that can be experienced, a dwarf planet. However, in this way, a collision that will create a large effect and create a large satellite may occur. In nature, such an object seems to have no possibility of existence. We end this episode. Until we meet again, goodbye.
