Milky Way vs Black Hole
The Milky Way was a spiral galaxy where the Solar System was located. It contained 100 to 400 billion stars, about the same number of planets, and a large number of star clusters, nebulae, and various types of interstellar gas and interstellar dust. The total mass was about 890 billion to 1.54 trillion times the mass of the sun, 90% of which was unknown and invisible dark matter. Black holes were mysterious and powerful celestial bodies. There were black holes in the Milky Way. For example, Sagittarius A*, which was located at the center of the Milky Way, was a supermassive black hole with a mass equivalent to 4 million times the mass of the sun. The supermassive black hole Sagittarius A* at the center of the Milky Way had an important impact on the stars in the Milky Way. For example, the star S5 - HVS1 was originally part of a pair of double stars. When they got too close to Sagittarius A*, the companion star was captured by the black hole, and S5 - HVS1 was thrown out at a very high speed by the powerful gravitational slingshot effect. It was currently escaping at a speed of 6 million kilometers per hour. In addition, scientists have also discovered other black holes in the Milky Way. For example, Gaia BH3 is currently the largest known stellar black hole in the Milky Way, with a mass 33 times that of the sun. From the relationship between the two, the black hole was a part of the Milky Way, but the strong gravitational force of the black hole would have a major impact on the movement and structure of the celestial bodies in the Milky Way.

Is the center of the Milky Way a black hole or a silver heart?
The center of the Milky Way was the Silver Core. The Silver Core referred to the area within 1000PC of the center of the Milky Way. There was a supermassive black hole (Sagittarius A*) in the center of the galaxy. This black hole was the center of the galaxy's dynamics, and its mass was equivalent to 4 million times the mass of the sun.

Dark Diga VS Milky Way
In " Galaxy Ultraman," the Dark Diga was re-appeared by the Dark Lukiel using the Dark Materialization of Diga Ultraman's Spark Doll. It was a strong enemy encountered by the Galaxy in the early stages and defeated Killer Zhan in one blow. However, the result of the direct confrontation between the Dark Diga and Galaxy Ultraman was not given. Therefore, it was impossible to determine the outcome of the battle based on the available information. " The Legend of the Three Dragon Scales in the Milky Way Continent " is equally exciting.

Neutron Star vs Black Hole
Neutron stars and black holes were both products of the late evolution of stars, but they had many differences. ** 1. Formation mechanism ** 1. ** The formation of neutron stars ** - After the core elements of the star were exhausted and transformed into iron elements through nuclear fusion reactions, the surrounding materials were pulled by gravity and fell rapidly towards the core. When the kinetic energy of the outer shell is converted into heat energy and explodes outward to produce a supernova explosion, the inner region of the star is compressed. If the star's mass is within a certain range (the lower limit of the mass is 10% of the sun, and the upper limit is about 2 - 3.2 times the sun), it may form a neutron star. During this process, when the white dwarf was compressed into a neutron star, the star was compressed violently, and the electrons in the composition of the matter were converted into neutrons. 2. ** Black Hole Formation ** - Black holes are formed when stars with a mass greater than 30 times the mass of the sun die. When a star died, it would continuously collapse under the effect of a huge gravitational force. Once the matter shrank into its own Schwarzschild radius, it would form a black hole. At its center was an infinitely small singularity, and the Schwarzschild radius was the range of its infinite curvature. ** 2. Physical characteristics ** 1. ** Densities ** - Neutron stars were the densest celestial bodies other than black holes. Their density ranged from 8×10¹ g/cm cubic to 2×10¹ g/cm cubic, which was about the density of atomic nuclei. One cubic centimeter of matter weighed one billion tons. However, the density of a black hole was even more extreme. Since its mass was concentrated on a singularity, the gravitational force within the Schwarzschild radius was infinitely large. In a sense, the density of a black hole was infinite. 2. ** Gravity ** - Neutron stars had a greater surface gravity than Earth, and their escape speed could reach half the speed of light. The surface gravitational field was extremely strong, and it could tear apart and devour stars that were close to it and within its gravitational range. However, the gravitational pull of a black hole was even stronger. Even light could not escape its horizon. Within the Schwarzschild radius of the black hole, the escape velocity was greater than the speed of light. 3. ** Rotation Speed ** - The neutron star retained most of the angular momentum of the parent star. Since the radius was only a very small amount of the parent star, the reduction in the moment of inertia led to a rapid increase in the rotation speed, which was very high. There was also research on whether black holes had a rotation rate, but the rotation of black holes was very different from the rotation of neutron stars in terms of nature and influence, and the rotation of black holes was more related to relativistic effects such as the distortion of space-time around them. 4. ** Magnetic Field ** - The magnetic field of a neutron star was between 10 and 10 times that of the Earth's magnetic field (100 million and 1 trillion). Its magnetic axis and its axis of rotation did not overlap. The radio waves and other radiations generated by the rotation of the magnetic field could be transmitted to Earth in a bright and extinguished manner (this was also one of the reasons for the existence of a neutron star like a pulsar). There was also a magnetic field around the black hole, but the mechanism of the black hole's magnetic field was different from that of a neutron star. It was mainly related to the movement of the matter in the accumulation disk and the angular momentum of the black hole. ** 3. Observation characteristics ** 1. ** Radiation characteristics ** - Because the magnetic axis and the rotation axis of the neutron star did not overlap, it would emit a periodic pulse signal (pulsar), which was a phenomenon of radiation such as radio waves. The black hole itself did not emit light, but due to its strong gravity, the surrounding matter would form an accumulating disk. The high-speed movement of the matter in the accumulating disk would produce strong electromagnetic radiation, which was one of the important basis for observing the existence of black holes. 2. ** Observation Difficulty ** - Neutron stars might have some advantages over black holes in terms of observation. For example, the pulse signal of a pulsar was easier to detect. Black holes were more difficult to observe directly. Their existence could be inferred by observing their effects on the surrounding matter, such as the change in the trajectory of the stars.

The Milky Way
Milky Way
The drawing of the Milky Way can be done by drawing an oval disc shape to indicate that the Milky Way is a huge oblate sphere. Draw four symmetrical spiral arms inside the disc (but there is also a new view that there may only be two main spiral arms, and the other spiral arms are scattered branches of these two). You can also draw some small dots in the Milky Way to represent the stars, because there are 400 billion stars in the Milky Way.

378. the Milky Way
The Milky Way is a spiral galaxy that contains the Solar System. It is between 100,000 and 180,000 light years in diameter and consists of about 100 to 400 billion stars and possibly 100 billion planets. The Solar System was about 26000 light-years away from the center of the Milky Way, located at the inner edge of the Orion Arm, which was filled with dense gas and dust. The Milky Way drew a galactic band of varying width on the celestial sphere. The widest was 30°, and the narrower was only 4° - 5°, with an average of about 20°. The oldest stars were almost as old as the universe, probably formed in the dark ages after the Big Bang. The Milky Way had a satellite galaxy, which was a member of the local galaxy group. It belonged to the Virgo Supercluster, which was part of the Lanikaia Supercluster. In China culture, the Milky Way was very important. There were stories about the Cowherd and the Weaver Girl in Han Dynasty literature. The Milky Way was only visible at night on a clear day. It was formed by the light of countless dark stars and was a part of the Milky Way. In addition,"Galaxy" was also used to name songs, Ultraman, and companies, such as the song "Galaxy,""Galaxy Ultraman," and China Galaxy.

The Milky Way
The Milky Way was a huge oblate sphere, shaped like an oval disc, with four symmetrical spiral arms (two main spiral arms, two secondary spiral arms). From Earth, it looked like a blurry 30° wide arched white light belt. The Milky Way contained 100 to 400 billion stars, about the same number of planets, and a large number of star clusters, nebulae, and various types of interstellar gas and dust. The central symbol was a strong radio source in Sagittarius A*, where there was a supermassive black hole with a mass of 4.100 + 0.034 million solar masses. The innermost 10000 light-years of stars formed a nucleus and one or more bands of radiation from the nucleus. The solar system was located at a radius of about 27000 light-years from the center of the Milky Way, at the inner edge of Orion's spiral arm. In addition, the Milky Way also had two larger satellite galaxies, the Magellanic Cloud and the Small Magellanic Cloud. Surrounding them were dwarf galaxies such as the Canis Major Dwarf Galaxy and the Sagittarius Dwarf Elliptical Galaxy.
