Quasar, an astronomical term, is the abbreviation of a star-like object, also known as asteroid, quasar or quasar radio source. Together with pulsars, microwave background radiation and interstellar organic molecules, it is also known as the "four major discoveries" of astronomy in the 1960s. It has long puzzled astronomers. Quasars are very distant celestial objects observed by humans. High-redshift quasars can be more than 10 billion light-years away from the earth. Quasars are high-luminosity objects observed at extremely long distances. More than 80% of quasars are radio quiet. Quasars are much smaller than galaxies, but the energy they release is more than a thousand times that of galaxies. The extraordinary brightness of quasars allows their light to be observed at a distance of 10 billion light-years. It is speculated that 10 billion years ago, there were more quasars. Quasars are a type of active galactic nuclei that are farthest from the Earth and have the highest energy. Quasars and pulsars, microwave background radiation and interstellar organic molecules were once called the "four major discoveries" of astronomy in the 1960s. Active Galactic Nuclei Theory Quasars are strange celestial objects with extremely high luminosity and extremely far distances. More and more evidence shows that quasars are actually a type of active galactic nucleus (AGN). A generally recognized active galactic nucleus model believes that there is a supermassive black hole at the core of the galaxy. Under the strong gravity of the black hole, nearby dust, gas and some stellar matter surround the black hole, forming a huge accretion disk that rotates at high speed. On the inside of the accretion disk, close to the black hole's event horizon, matter falls into the black hole, accompanied by huge energy radiation, forming a material jet. The strong magnetic field constrains these material jets so that they can only eject at high speed along the direction of the magnetic axis, usually perpendicular to the plane of the accretion disk. If these jets are angled toward the observer, quasars can be observed.

The concept and gun types of Personal Defense Weapons (PDW for short) have gradually faded out of the mainstream Western market after a period of excitement, but the demand for small arms by special operations forces still exists. So, Sig Sauer launched a mini assault rifle-MCX Rattler "Rattlesnake" in response to this demand. MCX Rattler "Sidewinder" assault rifle is the latest model of Sig Sauer's MCX series of rifles. The barrel length of this assault rifle is only 140 mm. It can only replace the barrel or piston barrel to fire 5.56 Mm bullets. It is known as the smallest rifle in the world. Sig Sauer named this assault rifle "Rattler" (meaning "Rattlesnake" in Chinese). So, why is this assault rifle named after a rattlesnake? According to the manager of Sig Sauer's rifle product department, when the designer fired this assault rifle in full-automatic mode for the first time, he felt that his teeth would make a "clicking" sound, so he subconsciously thought of it, which made people shudder to think of a rattlesnake. MCX "Sidewinder" is a highly reliable AR-shaped short-barreled rifle launched by Sig Sauer for the military and civilian markets, showing the company's extraordinary design strength. For a long time, designing a highly reliable gas-operated short-barreled rifle has been a difficult problem for many weapons design companies. Because the barrel is shorter, the gas hole will be closer to the chamber, and the chamber pressure here is higher. Correspondingly, the pressure of the gunpowder gas entering the piston barrel or gas tube is relatively high, resulting in higher energy obtained by the automatic machine, which will cause many unexpected problems. Obviously, the designers at Sig Sauer have overcome this problem very well. The MCX "Sidewinder" mini assault rifle may be the smallest assault rifle currently on the market. When the butt is unfolded, the total length is 597 mm. When the butt is folded, the total length is only 406 mm. In the folded state, the entire gun is only 76 mm longer than the HK MP5K submachine gun. MCX "Sidewinder" uses double recoil springs to greatly reduce the recoil impact of the automatic machine during shooting, making the recoil softer. The reciprocating movement of the entire recoil spring system occurs only in the upper receiver, allowing the butt to fold to the left. Moreover, when the butt is folded, it does not affect any of the shooter's gun handling movements and can still shoot normally. MCX "Sidewinder" has a shorter hand guard, only 127mm. The handguard is rectangular in shape, and the top of the handguard is integrated with the rail on the top of the receiver, allowing a variety of tactical accessories to be installed. There are also 2 M-LOK guide rail mounting holes on both sides of the handguard, and guide rails can be installed as needed. The reason why the MCX "Sidewinder" is known as the world's smallest assault rifle is because its barrel is only 140 mm long. It was previously unimaginable and difficult to implement such a short barrel on a gas-operated AR rifle.

Northwest desert. There is a "dragon" swimming in the sand sea. Its white body appears and disappears in the waves. Its back is like scales, flashing with little silver light in the sun. It is connected head to tail, boundless and majestic. This is White Dragon Fall, the no-man's land of the desert. White Dragon Pendant was once an ancient battlefield, where countless battles took place, countless heroes were shrouded in horse leather, and countless dead souls wandered here. Bailongdui, one of the three Yadan groups in Lop Nur, is located in the northeast of Lop Nur. It is a saline-alkali soil platform group. In the hot climate, the environment is very harsh. This landform was selected as the second place among the "Three Most Beautiful Yadan in China" by the "China National Geographic" "Beauty Pageant China" event. The earth platform of Bailongdui is made of gravel, gypsum mud and salt-alkali. It is gray-white in color and reflects little silver light when there is sunlight, like scales. Therefore, the ancients called this vast Yadan group "White Dragon". On the Gobi Desert far northeast of Bailongdui, there are faintly discernible traces of an ancient road, about 60 centimeters wide, running in the north-south direction. It is the ancient silk road that camels and horses walked in the past. Bailongdui is also the place where ancient cultural relics are most commonly found. After passing through Bailongdui from east to west, the ancient Silk Road bifurcated here, heading southwest to Loulan or west to Yingpan and Yuli, and heading north over Kuruktag Mountain to Turpan. It became a traffic turning point and was an important intersection among the ancient trade routes. People passing through this area have generally used most of their supplies. If there is a sandstorm for several days, people will be trapped and either starve to death or die of thirst. Therefore, most people will not enter this area from June to August every year.

Looking forward to new books✌️

Your setting is very big👍👍👍

CP fans come to vote for support~

New books are on the shelves. Damn, it's a hotspot for aliens👽. Aliens plan to colonize the earth and wipe out humans to 500 million! The reborn male protagonist evolved into a spiritual being. He stepped forward to protect the mother planet... The universe. The general term for all space, time and matter. "Zhuangzi": "The sun and the moon, holding the universe in hand, match it." "Yu" refers to all space, and "Cosmos" refers to all time. The latest research believes that the universe has existed for 13.82 Billion years, and the diameter of the universe reaches 92 billion light years. There are many living things in the universe, some of which have existed for hundreds of millions of years, so they have a high degree of evolution. In the 4.3 Billion history of the earth, many civilizations have been born and flourished, and countless interstellar civilizations have come and gone. Everything disappears in the long river of history. There is no record of who was the first civilization on Blue Star, and there is no evidence who are the real aborigines. Human beings are not the original inhabitants either. Even humans who consider themselves "indigenous" have the participation or intervention of other civilizations in the process of evolution. There are three basis for this. First, human bodies do not conform to the theory of evolution. Including fair skin that is not adapted to prolonged exposure to the sun, as well as lumbar spine and knees that are not adapted to gravity and work intensity. Second, there is fossil evidence of the history of ape evolution. From Yuanmou Man 1.7 Million years ago to the Shanding Cave Man 30,000 years ago, stone tools have always been used. Although at a certain stage there were pottery products and advanced agricultural technologies that were "taught by alien civilizations and then lost", they finally returned to stone tools. This shows that the normal rate of evolution is very slow, and it still remains stagnant for millions of years. Third, there is no ability to predict. Animals on the earth can sense the abnormal frequency of the earth and predict natural disasters such as large earthquakes and tsunamis, but humans have no ability to predict. If apes evolved into Homo sapiens, and Homo sapiens evolved into today's humans, today's humans should be able to adapt to the earth's environment. According to Darwin's theory of evolution, if humans evolve at a normal rate, according to the evolutionary cycle of great apes, today's humans should be hunchbacked, use both hands and feet, have thick body hair, can live in the sun for a long time, live in caves, live in small groups, and have the ability to predict large-scale natural disasters on the Blue Star. Tools developed into the age of stone drilling, and artificial fire was made. Perhaps the use of fire entered the early Bronze Age. From the author's point of view, humans are partially or completely alien creatures. Or maybe humans are the "mixed" descendants of interstellar guests. "The book assumes that humans are the descendants of little blue people and apes." Perhaps humans have had their genes modified by visiting guests. Conclusion: In other words, humans have been "participated" by other civilizations in the process of evolution. Compared with the lifespan of the earth and the universe, human history is too short, and Blue Star has experienced several major destructions. Greater China only has 5,000 years of civilization, and primitive Homo sapiens only has a million years. Ten million years after the disappearance of human beings, the glass residues buried deep underground may have become the last evidence of human civilization on the upper levels of the earth. One hundred million years after the disappearance of human beings, nature may have cleared away all evidence of human civilization, and it has regained control of the laws of survival of the earth. If a new civilization reappears on this planet, they will not even discover that other primitive civilizations once existed here. Blue Star can live without humans, but humans cannot live without Blue Star. Whether before or after human civilization, Blue Star will not slow down its reproduction pace because of the survival of human beings. Perhaps Blue Star civilization is just reincarnating in the constant demise and reconstruction, and we, human civilization, may be just one of these many unknown civilizations.

A new bolt-action rifle named "Phantom H" has been unveiled to the public. It is said that this rifle was developed by a Russian company called Bespoke Gun. As the name suggests, this company specializes in the business of customized rifles. Judging from the information disclosed so far, this is a new company jointly established by a Russian small arms manufacturer and the Moscow Arms Company. The most attractive thing about this gun is the shape of its carbon fiber stock. All inclined surfaces are composed of flat surfaces and edges, giving it a futuristic appearance. According to Izvestiya, the geometry of the stock is designed to help the shooter operate the rifle in the most efficient manner. If you hold or carry it the "wrong" way, it will be very uncomfortable. The length of the butt and the height of the cheek plate can be adjusted, and it is equipped with a "pepper bottle" shaped muzzle device. There are Picatinny rails on the top of the receiver and the front under the handguard, which can accommodate various scopes and bipods. The "Phantom H" adopts a newly designed bolt action. From its design, it absorbs some elements from Accuracy International, Tikka and Remington. The bolt adopts a three-protrusion bamboo shoot design, with a detachable magazine for ammunition. The trigger group is "compatible with Remington (probably Remington 700)". The Custom Firearms Company claims that in the "hands of experienced shooters" the accuracy of the "Phantom H" can reach 0.1MOA, which is said to be the highest accuracy a shotgun can achieve and is close to the standard for fixed bench test guns. To demonstrate the authenticity of the accuracy, Custom Firearms released two photos of target paper showing the spread of three rounds of ammunition at 100 meters. This is the dispersion of five rounds of ammunition at 100 meters. It can be seen that the accuracy is excellent. Currently, there is only one caliber .300 Winchester Short Magnum (.300 WSN) on the official website, equipped with a 406mm long heavy barrel, with a total length of 985mm and an empty gun weight of 4 kilograms. The initial velocity is 930 meters/second, and the effective range is 1,000 meters. The one on the right is the .300 Winchester Short Magnum ammunition, which uses a .404 Jeffrey-based cartridge and uses a larger diameter to shorten the length of the ammunition. Therefore, a bolt with a length of .308 Winchester ammunition can be used for firing, while the ordinary .300 Winchester Magnum ammunition (left) must use a longer 30-06 length bolt, which affects the loading speed, the size of the firearm is larger, and the manufacturing cost is relatively high. Oleg Rogozhin, one of the designers of the gun, said that based on previous mature designs, ready-made components produced abroad were used to manufacture the main structure as needed. From this perspective, the gun likely uses a custom Remington 700 trigger assembly. Firearms with such advanced designs appeared on the Russian market for the first time. Russia only began to imitate such high-precision firearms a few years ago. However, ready-made drawings and materials are obtained from foreign manufacturers. After the sanctions, such production can no longer continue. Therefore, the emergence of "Phantom H" is not only a breakthrough in the gun stock, but also a breakthrough in the Russian firearms manufacturing industry. Designers and technicians must solve multiple technical problems, so they need to absorb the time-tested and mature technology of their Western counterparts and solve a series of problems with high-precision rifles in the drawings and sample gun manufacturing processes. Another difficulty is mass production, so it is necessary to find raw materials that meet the standards. For this purpose, test equipment must be prepared, prototype guns and test samples must be manufactured. However, there are currently no suitable metal materials in Russia that can meet the manufacturing standards of the "Phantom H", so raw materials have to be imported to maintain production. It should be noted that there have only been a few companies manufacturing high-precision firearms in Russia in recent years, and the output is not high. Therefore, metallurgical companies cannot be required to provide them with special types of metal. I believe that this problem will be solved in the future. In any case, the "Phantom H" rifle developed by the Russian Custom Firearms Company has an accuracy of 0.1MOA, which is indeed amazing. It completely gets rid of the traditional image of Russian-made firearms as "silly, big, black and thick" and can be compared with similar types of firearms in Europe and the United States.

Rational explanation of rebirth Rebirth is hot... We live on the earth in a three-dimensional space. Three dimensions are XYZ, and you are a three-dimensional 3D existence. Rebirth can be understood as "consciousness" traveling through time and space and returning to the past. You in the three-dimensional world are like a "frame" on a movie film. And rebirth is to replace a certain grid of yours with a certain grid position in the past. Who has this ability? You from the four-dimensional space, or someone else. This is the four-dimensional space "intervening" in the three-dimensional space! The fourth dimension is the space where human spirit and body are separated, which is also the space of consciousness! Reborn, the consciousness returns to the past in the four-dimensional space and becomes stronger due to rebirth. The reborn person will not remember what they have done or what happened in the four-dimensional space. It is impossible to bring matter from four-dimensional space to three-dimensional space! Rebirth may have memories of the four-dimensional space! Talking about the mystery of three-dimensional space. In the three-dimensional space, Taoists can enter the four-dimensional space through practice. The third realm of cultivation is "refining the spirit and transforming the void". At this stage, physical cultivation is transferred to spiritual cultivation, which warms and nourishes the yang spirit, leads to clear wisdom and comprehensive understanding. In the end, he refined the emptiness and the Tao, and became a true immortal. Explore the rules of the world, break free from the fetters of the physical body, and the Yang Shen comes out of the body. Exactly: I don't need a boat to reach the other shore, and I have a golden body when I leave the void. This is "the soul enters the four-dimensional space". Buddhism says "... Beyond the distance of the earth, the past and future of time, all phenomena can be clearly seen. This is the ability after opening the third eye. This is also the skill of the four-dimensional space!

Black hole Black hole (English: Black Hole) is a celestial body existing in the universe in the modern general theory of relativity. The gravitational pull of a black hole is extremely strong, causing the escape velocity within the event horizon to be greater than the speed of light. Therefore, "a black hole is an object whose curvature of space-time is so great that even light cannot escape from its event horizon." In 1916, German astronomer Karl Schwarzschild obtained a vacuum solution to Einstein's field equation through calculation. This solution showed that if the actual radius of a static spherically symmetric star is less than a fixed value, strange phenomena will occur around it, that is, there will be an interface - an "event horizon". Once entering this interface, even light cannot escape. This fixed value is called the Schwarzschild radius, and this "incredible object" was named a "black hole" by the American physicist John Archibald Wheeler. Black holes cannot be directly observed, but their existence and mass can be known indirectly, and their impact on other things can be observed. Information about the existence of a black hole can be obtained by emitting "edge information" of x-rays and gamma rays due to the friction caused by the acceleration caused by the gravity of the black hole before the object is sucked in. The existence of black holes can also be inferred by indirectly observing the orbits of stars or interstellar clouds, and their position and mass can also be obtained. At 21:00 on April 10, 2019, Beijing time, the first photo of a black hole was released. The black hole is located in the center of M87, a giant elliptical galaxy in the constellation Virgo. It is 55 million light-years away from the earth and has a mass of about 6.5 Billion times that of the sun. There is a shadow in its core area, surrounded by a crescent-shaped halo. Einstein's general theory of relativity was proven to hold true under extreme conditions. At 10 pm on March 24, Beijing time, the Event Horizon Telescope (ETH) collaboration in which Chinese scientists participated announced the latest research results: an image of the M87 supermassive black hole in polarized light was discovered.
