At the center of the Milky Way is the Silver Heart. The galactic center is the intersection of the Milky Way's axis of rotation and the galactic plane, the center of the galactic core, and the center of the Milky Way. The Silver Heart is located in the direction of Sagittarius.
This region is mainly made up of a large number of stars. The mass of the silver core is about 4 million times the mass of the sun. Some people think that the galactic core region is a massive dense nucleus, perhaps a massive black hole.
By the way, a word about the silver core. The silver core is a slightly convex part of the Milky Way**. It is a very bright spherical body, about 20,000 light-years in diameter and 10,000 light-years thick.
This region is made up of a high density of stars and interstellar matter, the main of which are old red stars that are about 10 billion years old. The activity of the silver core is very intense.
Note that the silver core and the silver core are two different concepts, the silver core is a point and the silver core is a region.
-
The sun is near, the earth receives more radiation, and although the silver heart is large and bright, it is far away, and there is not much left after the divergence, and there is not an absolute vacuum of light and attenuation.
For example, on a ship in the sea at night, although the light of the lighthouse in the distance is not as bright as a small flashlight on the ship, the absolute brightness is not known to be many times greater.
Even in the solar system, when Pluto looks at the sun, he is not bigger than the tip of a needle, and he can't distinguish it from Proxima Centauri, and he doesn't know that he is a member of the solar system.
I can't give you the data if you want it, but I have an impression that in high school, there was a question about how many photons a celestial body emits and how far it can be seen. Just remember that as soon as the distance was away, there were not many photons left.

The Milky Way is the star system in which the solar system is located, including 120 billion stars and a large number of star clusters, nebulae, and various types of interstellar gas and interstellar dust. Its total mass is 140 billion times that of the Sun. Most of the stars in the Milky Way are concentrated in an oblate sphere of space, which is shaped like a discus.
The protruding part of the oblate sphere in the middle is called the "nuclear sphere", with a radius of about 7,000 light-years. The middle part of the nuclear ball is called the "silver core", and the surrounding area is called the "silver plate". Outside the silver disk there is a larger sphere, where there are few stars and less dense, called the "galactic halo", with a diameter of 70,000 light years.
The Milky Way is a spiral galaxy with a spiral structure, i.e., with a galactic core and two spiral arms, which are 4,500 light-years apart. The speed and period of rotation of each part of the silver vary depending on the distance from the silver core. The Sun is about 10,000 light-years away from the galactic center, orbiting it at a speed of 250 kilometers and seconds, and the period of its rotation is about 100 million years.
Earth is just in an inconspicuous solar system in the Milky Way.

At the center of the Milky Way is a huge black hole. I can't see it because we're too far away from it.
-
In the middle of the Milky Way is a black hole.

The center of the Milky Way is called the galactic core, also known as the galactic core, the galactic core is a very special place, it emits strong radio, infrared, X-ray and ray radiation, the nature of the galactic core is not yet known, there may be a giant black hole, it is estimated that its mass may reach 2.5 million times the mass of the sun. At a distance of 70 parsecs from the galactic center, the ionized hydrogen region with a violent disturbance expands outward at a high speed, and at a distance of 300 parsecs from the galactic center, there is a cloud of hydrogen molecules with an average diameter of 30 parsecs that rotates rapidly around the galactic core, and the hydrogen molecular cloud also expands outward at a speed of 70 to 140 kilometers per second.
Because the center of the Milky Way is so densely populated that astronomers can't observe it.

It is a patchwork of several Chandra X-ray Observatory images of the central region of the Milky Way**, containing hundreds of white dwarfs, neutron stars, and black holes in the white light of hot gas. The supermassive black hole of the Milky Way** is hidden in the white specks of Figure **. The colors in the diagram represent the energy bands of the X-rays – red for the low energy band, green for the medium energy band, and blue for the high energy band.
This stitching provides a new perspective on how regions of galaxies affect galaxy evolution as a whole. Analysis of X-ray data shows that the temperature of the gas does not necessarily have to reach 100 million degrees Celsius. Perhaps, 10 million degrees will do.
These hot gases make their way to other parts of the galaxy. The outflow of gas, mixed with chemical elements thrown out when the star is destroyed, gradually enters the edge of the galaxy. With only 25,000 light-years from Earth, the center of the Milky Way provides us with an ideal place to study galactic nuclei.

Gravitational attraction is the mass possessed by matter that causes the bending and depression of space-time around it. At the center of the Milky Way is a supermassive black hole, and its massive mass distorts and conjectures the space around the Milky Way, thus binding all subgalaxies and celestial bodies outside its event horizon, thus keeping them in balance with each other in classical mechanics.
-
Most people think that the center of the Milky Way is a black hole, but some people think that the center of the Milky Way is a white dwarf.
-
The Milky Way is actually a barred spiral galaxy, and the brightest region in the middle is called the silver nucleus, and the central region of the Milky Way is very bright because there are a large number of stars emitting light.
But because the solar system is about light-years away from the center of the Milky Way, and there is a lot of interstellar dust in this interval, it will not be clear from the surface of the Earth.
-
Although the Earth is in the Milky Way, the Solar System is located at the edge of the Milky Way, and the Milky Way is a rod-shaped rotating body with two rotating arms. The Milky Way is a collection of celestial bodies, the Earth is only one of them, and the various celestial bodies are not connected, so standing on the Earth, you can see the collection of other stars in the Milky Way.
In various geological periods, the major events that occurred in the cosmic space related to the earth, the solar system and the earth have left records in the earth itself, crustal movements, strata, rocks, tectonics, paleontology, paleomagnetism, glaciers, paleoclimate and other aspects. In different geological periods, the geological processes are different and the characteristics are different.

What if the Earth were at the center of the Milky Way? In reality, we all know that this cannot be what it is, and if it is, the earth is no longer what it is nowBecause it is located in the center of the Milky Way, and has not yet been affected by the unlocking of other celestial bodies, the mass and volume of the Earth itself should be countless times larger than it is now. <>
If the mass and volume of the earth itself are countless times larger than now, then this gravitational condition, which is the so-called gravitational condition, should also change the water environment on the earth, and the composition of the air may also change, because if it is the center of the Milky Way, it is not a planet, it is a rampant, otherwise why is it said to be the center, the center means that it is fixed like the sun in the solar systemThe position is always determined, and it is only the center of the other planets that revolve around it. <>
But if the earth is the center of the entire Yinpai river, then why do humans still exist on the earth? Because we all know that stars are glowing and hot, do you want the earth under your feet to be hot all the time, and there is a high brightness, can humans survive on it? Impossible, even if there were still living creatures on the earth at that time, then it would not be called human beings, and it would not be us now.
Even the center of the solar system, the sun, itself emits light and heat far beyond what current humans can bear, so you think about the center of the entire galaxyAll the stars of the Milky Way orbit the Earth, so what is the mass of the Earth itself? Planetary stars that can attract the entire galaxy. <>
Because the Milky Way is very large, so big that we can't imagine that the mountains and suns where the earth is located, it is just that the position of almost five rings and six rings in the Milky Way is relatively partial, but it is not particularly biased to look at a very inconspicuous earth in the details, placed in the entire Milky Way, it is even more insignificant, let alone compared with the Milky WayThere are many galaxies bigger than the Milky Way, and the broadcast universe is far from what we can imagine.

1. The center of the Milky Way is a dense area of some high-brightness stars, and the closer the position of the earth is to the central region, the more radiation the earth will receive, and this environment will directly prevent the formation of new life on the earth. 2. If we move to the center of the Milky Way, the earth's magnetic field will be destroyed due to radiation, and the atmosphere will be ionized, and the earth's climate will usher in earth-shaking changes. If you can survive these extreme conditions, it doesn't mean you can live in the center of the galaxy before the noise, because there are many supernovae there.
3. The Earth's transfer to the center of the Milky Way has the greatest impact on people about supermassive black holes. Among the many black holes, there is a black hole called Sagittarius A. This huge black hole has an event horizon of up to 20 billion kilometers, and once the Earth gets close, we will be broken down into the most basic particles, and the Shengdanqing will completely disappear from the universe.

If the Earth had been at the center of the Milky Way, I don't think it would have been the same as it is now, and it would still rotate normally, and nothing would have changed.
-
If the Earth were at the center of the Milky Way, you would be able to see many planets, and you would be more in a huge space.

The center of the Milky Way is the intersection of the Milky Way's axis of rotation and the galactic plane, and the Milky Way's nucleus, the silver core, is in the direction of the constellation Sagittarius. In terms of right ascension and declination, it is at 29°00 in right ascension and 29°00 in the year 2000, and this "point" is not far northwest of Gamma, near the border between Ophiuchus and Scorpio.
People use optical telescopes to try to peek into the secrets of the center of the Milky Way, and although people have the ability to make optical telescopes bigger and bigger, and can look farther and farther, they still can't see the true face of the center of the Milky Way. It was only later that the reason for this was figured out, and it was because there was a large amount of dust near the silver heart, which could obscure people's view like a white hazy fog or a yellow hazy sandstorm that blew up.
The rapid development of infrared astronomy, radio astronomy and X-ray astronomy has provided astronomers with new observational tools and means to explore the mysteries of the center of the Milky Way, because infrared, radio waves and X-rays can all pass through the dust barrier. In this way, infrared, radio waves, and X-rays from the center of the Milky Way are like messengers from the center of the Milky Way, giving us some important information about the center of the Milky Way.

Our exploration of the universe has continued and never stopped, and from the fact that we are now getting more and more complete about the moon landing, we already have a certain understanding of the universe, and the closest to us may be the galaxy we have defined, because our earth is in the galaxy. But what do you know about the Milky Way, and what is the center of the Milky Way, in fact, the Milky Way is equivalent to our small villages, all kinds of planets and planets living in such a large area, and the center of the Milky Way is equivalent to the center of each village, but in the universe, the center of the Milky Way is a very bright spherical shape. He resembles a very large red star, but there is speculation that there may be a huge black hole in the middle, and the center of this galaxy is relatively close to the constellations Ophiuchus and Scorpio.
According to our modern understanding, the center of the Milky Way is very far away, and its biggest feature is that it is very bright like a star, because none of us have actually seen the center of the Milky Way, just speculate through some data or some brief **, because our universe is through the universe **, and formed a variety of places and this phenomenon, maybe the center of the Milky Way is the center of the universe. <>
Along with our curiosity about the universe, there are more and more studies on the universe, but we can touch such a position in the center of the galaxy that we now have a certain understanding of the universe. Or the center of the Milky Way is equivalent to a very large sun, because of its very large mass, and through our observation of it, the center of the Milky Way is very dangerous, because it is very dense and has a very large attraction, and the surrounding planets and stars can maintain such motion, probably for a certain reason with the center of the Milky Way. <>

Some scientists believe that there is also a supermassive black hole at the center of the universe. As the most mysterious celestial body in the universe, we all know that black holes can devour everything and have a huge gravitational pull. So, let's say that the center of the universe is a superblack hole around which all celestial bodies revolve.
As the universe expands and grows, this black hole continues to devour the matter around it, thereby strengthening itself and maintaining the balance of the universe.

The center of the Milky Way is the intersection of the Milky Way's axis of rotation and the galactic plane, a region made up of high-density stars, massive masses and compact structures, and so on.

The Peace System does not have a center, because the Milky Way is constantly moving, so there is no fixed center.
Give so many points, I'll also join in the fun. The landlord's question is of little practical significance, referring to the upstairs Du Kang and nostalgia. Bigger than China is the world, bigger than the world is the Earth-Moon system, larger than the Earth-Moon System is the Solar System, larger than the Solar System is the Milky Way, larger than the Milky Way is the total galaxy, and there is no definition of a universe larger than the total galaxy.
What is the secret of the giant black hole at the center of the Milky Way?
The solar system moves fast enough to compete with the gravitational pull at the center of the Milky Way, because the black hole is 25,000 light-years away and has a very weak gravitational pull on us. >>>More
There are 3 main types of heat in the depths of the earth**:(1) the heat generated when the earth was formed; (2) the heat generated by friction when the core material sinks to the center of the earth; (3) Heat generated by the decay of radioactive elements. The release of the earth's heat takes quite a long time. >>>More
