    This is the orbit of the star at the center of the Milky Way, and the red color is the gas cloud, and the observations of the past two years show that the gas cloud is rotating around a point. By working with these persistent orbits to calculate the position of the central black hole, which is not a black hole, it is a huge object with an invisible mass, and the mass of the central black hole can be deduced from the mass of about 4 million suns based on the radius, velocity, and mass of the star around which it orbits. So it's basically determined that the center of the Milky Way is a supermassive black hole.

    Of course, the center of the Milky Way is not as close together as everyone thinks, and in astronomical terms of calculating light years, stars are just markers, with negligible diameters.

    The composite color infrared image shows a new group of stars at the center of our Milky Way, as well as new details of the complex structure in the thermoionized gas near the center 300 light-years. This panorama is the clearest infrared image ever created at the center of the Milky Way. Astronomers have now discovered that massive stars are not confined to one of the three star clusters known to the center of the Milky Way, namely the ** Star Cluster, the Arch Cluster, and the Pentuplet Cluster.

    These three clusters of galaxies can easily be seen as dense concentrations of bright massive stars in the image. These distributed stars may have formed in isolation, or they may have originated from star clusters that were disrupted by the strong gravitational tidal forces. At the center of the image, the ionized gas surrounding the supermassive black hole at the center of the galaxy is confined to a bright spiral embedded in the inner tubular torus of a nucleus of dust.

    On November 6, 2004, astronomers used the orbiting Chandra X-ray telescope to observe the core of our Milky Way, 26,000 light-years away. The spectacular pseudo-color image spans about 130 light years. It reveals an energetic region, rich in X-ray sources, and is known to be a supermassive black hole with a mass of 3 million times the mass of the Sun.

    Considering its enormous mass, Sagittarius A is surprisingly faint in X-rays compared to the central black hole observed in distant galaxies, even in its frequent X-ray flares. This suggests that the supermassive black hole has been starving due to a lack of material that will not fall. In fact, the Chandra image shows a cloud of gas of millions of degrees located in the central region, suggesting that the violence has cleared much of the material near the black hole.

    The galactic heart is a giant black hole where intense activity is taking place. It is surrounded by a large number of stars or dense clusters.

    Black hole. Scientists have discovered that not only is there a black hole (supermassive black hole) at the center of the Milky Way, but almost every galaxy has such a black hole at the center. Black holes are not only destroyers, but also creators, and their powerful power has created the operating order in the galaxy!

    It is the basis for the formation of galaxies! So how did astronomers discover that the center of a galaxy is a black hole? On the basis of long-term observation, it takes more than ten years or even decades of continuous observation, and then summarize and compare!

    Black holes cannot be directly observed because they do not emit light, but astronomers can indirectly learn about the existence of black holes by observing the strange motion patterns and laws of celestial bodies (mainly stars)! For example, when astronomers observe the movement of stars near the center of the Milky Way, they find that the stars are moving very fast, so they deduce that there must be a gravitational object in the center of the Milky Way, otherwise the surrounding stars must be thrown out so fast! At the same time, astronomers also discovered that there is an extremely bright eruption of cosmic rays at the center of the Milky Way (which we now know is a quasar), and later studies found that it is the huge energy released by the powerful gravitational pull of the black hole in the process of swallowing the surrounding gas clouds and even stars!

    Further calculations show that the mass of the black hole at the center of the Milky Way is 4 million times that of the Sun. Our Sun orbits a supermassive black hole at the center of the Milky Way, and it takes about 100 million years to do it!

    The center of the Milky Way is both a black hole and an asterism. The center of the Milky Way galaxy is called the star core, which is a bulging bright ball, also known as a nuclear ball. This bright ball protruding in the middle is about 20,000 light-years in diameter and about 10,000 light-years thick.

    This region has a high density of stars, so it is very bright and bright, and there is a dense concentration of older stars, about 10 billion years old. The silver heart is also a place that is not calm, on both sides of the silver heart there is a huge hydrogen flow expansion arm, constantly pouring in from one side at high speed, and leaving from the other side at high speed, this river of mass surging up to 10 million solar mass. These neutral hydrogen molecules pour in at a distance of 4,000 parsecs (more than 13,000 light-years) at a speed of 53 kilometers per second, and flow out at an even faster rate.

    About 930 light-years away from the galactic core, there is a hydrogen disk nearly 100 light-years in size that rotates rapidly around the galactic core, expanding outward at a speed of 100 kilometers per second. Therefore, the silver heart is not calm, and there is a lot of turbulence and activity.

    The Milky Way is a barred spiral galaxy of 100 billion to 400 billion stars, thousands of star clusters and nebulae that look like a large disk with a slightly bulging center. It looks like a swirl when viewed from above. There are four spiral arms extending evenly and symmetrically from the center of the Milky Way.

    The center of the Milky Way is the galactic center, that is, the intersection of the Milky Way's axis of rotation and the galactic surface, and the part with a slight bulge in the center is the galactic core. The galactic center is a bright spherical region 10,000 light-years thick and 20,000 light-years in diameter, composed of a dense density of stars, mainly some old red stars that are tens of billions of years old, and there is much evidence that there is a large black hole in the central region. The activity of the silver core is very intense.

    The diameter of the silver core is 1 parsec (light years). It has millions of solar masses, 1 million of which are in the form of stars, and at its center there is a massive dense nucleus, most likely a giant black hole.

    With a diameter of about 160,000 light-years and more than hundreds of billions of stars, the center of the galaxy that can lead such a huge constellation is definitely a gravitational superpower, and the stellar group cannot handle this task, and this burden undoubtedly falls on the black hole! Black holes can not be directly observed, in addition to gravitational lensing, there are super strong X-ray flares produced by accretion disks (which also shows that the galactic black hole is still growing), which is also one of its direct evidence, relevant institutions believe that the Milky Way was born 12.6 billion years ago, theoretically before this black hole should have existed, the current general theory is that black holes were born before galaxies, because only black holes have unlimited mass growth potential and the consequent super gravity can hold so many little brothers! The galactic black hole is supposed to have evolved after the evolution of the first stars 1-200 million years after the universe, and due to its infinite potential, it has gradually become the core of galaxies, and the stars that continue to orbit it have also continuously transported matter to it.

    The evolution of the Milky Way, from the initial formation and growth of 12.6 billion years ago to the present, the galactic black hole has also grown to a supergiant with a mass of 4 million times the sun!

    Many scientists believe that the supermassive black hole Sagittarius A* is right at the center of the Milky Way. This theory is plausible because radio has been found to emerge from there, black holes are thought to produce such signals, and supermassive black holes are often falsely located in the center of galaxies. At the heart of our galaxy, there may be thousands of smaller black holes around Sagittarius A.

    It is understood that the researchers focused their research on the case of a black hole revolving around a supermassive black hole. When this happens, a large amount of X-ray energy is generated, and at that time, scientists will be able to detect these large ** and the X-rays that are subsequently produced and continuously released – even if they are far away from Earth. With this in mind, scientists have set out to study the number of black holes near Sagittarius A.

    To get a rough estimate, the team focused on separating the X-ray energy of the black hole that has already captured the star. Using a formula they developed, the researchers began to look for small black holes near Sagittarius A. Eventually, they concluded that there were hundreds of stellar black holes in the region, and that there might be thousands more independent black holes to fill the gaps.

    For this question, I think I will start with how the Milky Way was formed. According to the entire appearance structure of the Milky Way, it should be a chain reaction caused by the spread of countless giant stars or dust by the shock wave after the universe, and then collide with each other. If it is the Milky Way created by the collision of giant dust after the universe, then it is possible to create countless black holes in the Milky Way, and the spiraling big black hole swallows the small black hole, so it is also possible to form a giant black hole.

    If the megastars clash against each other to produce a large ** formed Milky Way, then the center of the Milky Way should be dominated by solid stars and planets, and the corresponding black holes will be less ......

    Is there nothing else in the entire galaxy except for these visible materials such as stars and star clusters and nebulae? We know that in the solar system, the sun, as the central celestial body, accounts for more than 99% of the mass of the solar system, and the eight planets revolve around the sun, and the closer to the sun, the greater the gravitational acceleration of the planet, and the greater the rotational speed of the planet must be in order to produce a centrifugal effect to balance this acceleration. But in fact, in the Milky Way, the speed of the stars near the galactic center around the galactic center is not faster than that of the stars on the outer edge of the galactic galaxy, which means that the mass of the star system is not concentrated in the galactic center, and there must be a large amount of invisible matter in the outer periphery of the galactic system.

    Therefore, the result of calculating the total mass of galaxies by gravity is 10 times that of calculating the total mass of galaxies by using celestial stars, so scientists believe that there must be a large amount of dark matter in the Milky Way, after calculation, the total mass of the Milky Way is 1 trillion solar masses, of which the total mass of all stars in the Milky Way is 100 billion solar masses, and there are other star clusters and nebulae dust is about 40 billion solar masses, and the remaining more than 860 billion solar masses are dark matter and black holes with silver hearts. This black hole, if it exists, only has 4 million solar masses, which is nothing compared to the dark matter in the Milky Way. In summary, according to the current understanding, the center of the Milky Way, the galactic core, is a high-density stellar group, and there is a 4 million solar-mass black hole in the central region of the galactic core.

    At the center of the Milky Way is a cosmic vortex consisting of a black hole, a wormhole, a white hole, a quasar, and a vortex nuclear disk. The brightest place on Earth where the galactic core is seen is a white hole, which rotates and constantly erupts neutrons and elementary particle matter, expands to form spiral arm matter, and then differentiates to form stars, planets, and then the Milky Way. The mouth of the White Hole is made of molten and plasma-like matter that accumulates into a giant quasar that emits light and heat.

    Behind the white hole is a huge rope-shaped wormhole. Behind the wormhole (on the other side of the vortex) is a black hole, swirling and not emitting light. Black holes, wormholes, white holes, quasars are wrapped around the outer layers of a huge vortex core disk, which is constantly rotating rapidly.

    The cosmic vortex at the center of the Milky Way is the engine that rotates the Milky Way, the manufacturing plant for stars and planets in the Milky Way, and the heart of the Milky Way. In order to understand the material composition of the center of the Milky Way, in addition to improving the level of detection technology, we must also improve our ability to reason and imagine. The wormhole at the center of the Milky Way galaxy can only be understood by reasoning and imagination, and it is currently difficult to detect.

    The current mass of the black hole at the center of the Milky Way should be about 200 billion solar masses, but the black hole at the center of the Milky Way has no gravity, and the black hole at the center of the Milky Way not only does not have gravity, but also does not absorb light electromagnetic wave neutrinos, because the black hole at the center of the Milky Way is already the explosive stage of the black hole, that is, the stage of spitting out protons. Black holes also have no gravitational attraction at the beginning of their formation, absorbing light, electromagnetic waves, neutrinos, etc., but not swallowing protons and substances larger than protons. Black holes absorb light, electromagnetic waves, neutrinos, etc., not because of gravity, but because of another force that exists in the universe, which has no effect on protons and particles larger than protons.

    Needless to say, it must be a star, because it has the ability to absorb external matter, and it must use the gravitational pull of the eternal star, so I named him a black star, I don't know if he can win the Nobel Prize.

    A black hole is the core that forms a planet and has a huge gravitational pull and mass. Attracting dust and small celestial bodies in space, and forming planets, the gravitational mass determines the size of the planet. In addition to all the material outside the Earth, the Earth's core is also a black hole.

    When the black hole is large enough, it will form stars in the future, such as the Sun. The gravitational pull is so strong that it can also cause nuclear fusion, which is not difficult to understand why the sun shines and heats up the core of the earth, or the deeper the earth goes, the hotter it gets.
