A black hole is one such monster of the universe that has many secrets in it.
Who discovered Black holes?
Let us examine each of its zodiac signs but discuss the black hole in detail. The first scientist to reveal his views to the world about the black hole was Professor John Mitchell Michal, a teacher at Cambridge University and he gave his views about the black hole in 1783. After him, in 1796, a French scientist, Pierre Simon, talked about blackholes in his book The System Now World.
What is inside a Black hole?
A black hole is a body of evidence whose gravity is so strong that even light cannot pass across it and everything in or around its gravitational circle in space takes out the black hole. Not only this, the time we got nearer to the black hole, the effect of time also decreases and there is no existence of time inside the circle of a black hole.
How do Black holes form?
So let us know how such an interesting back is generated in the whole universe. A black hole is a mass and mass body. If we compress any object in the universe and make it very small, then its mass and density will make its gravitational force so strong that it will not be possible for light to go out of it. But that thing will be called a black hole. If the density of our Earth increases greatly and the entire Earth is compressed and the sensed forest purifies it, then its gravity will increase and it will become a black hole. If our Sun, which is 13 million times larger than the Earth, is also compressed to the size of a small pea, it will also become a black hole. But remember that density is much more important than mass in a black hole. We know that the Earth and the Sun cannot be compressed in this way because neither the mass of the Earth nor the force of gravity is so high nor that of the Sun. But if there are a star billions of times larger than our Sun, whose mass and density are present in it, it can become a black hole by its characteristics.
Often black holes are made of stars, so before understanding the creation of this black hole, we understand how the stars are formed.
Stars originate from dust and gas clouds present in proof galaxies. Dust in the universe and how these clouds are formed are called a nebula. This nebula has the highest nitrogen content and helium up to about 25 percent and also contains a small amount of other heavy elements. When the clouds increase in the density of these clouds i.e. Nebula beyond, at that time these clouds start to shrink due to their gravity and the temperature inside it increases so much that the nuclei of hydrogen start colliding with each other and that helium They form nuclei and due to movement and contraction, they converge in unison to form a round or almost similar shape and thus form a star. But many millions of years pass in these processes.
Our Sun was also formed in this way. Now the heat of the stars remains in equilibrium due to the intense heat generated by nuclear fusion. Therefore, when the hydrogen present in the stars is exhausted, that star starts cooling down slowly. Now an object four times the mass of its own solar mass that has finished itself, cannot handle itself against its own gravity, an explosion occurs inside such stars called supernova. After this explosion, if any denser residue of that star survives, it becomes a neutron star with very high density.
Due to the immense gravitational pull on such stars, the star starts to compress or compress, and eventually, the star narrows to a certain critical limit or critical limit and due to this immense extraordinary contraction its space and time also get distorted and Because of the existence of space and time, it becomes invisible and these are the invisible bodies that we call black holes.
The entire mass of a black hole is centered in a small point called a singularity. The circular boundary or horizon around this point is called the event horizon. Light or any object cannot go outside this event horizon and time does not exist even if desired. According to Einstein's Special Theory of Relativity, an observer standing at a certain range away from the horizon of this Planck shell will be clocked at extremely slow speeds and the time there will be very slow. Remember that time is absolute and the flow of time is indifferent speeds in different places of the universe. This means the time that is going on the earth. Somewhere in the universe must be moving faster or slower than that. This is called time division.
This is a very interesting reality of a verb on mane or no mane. The molecules of any object falling inside the black hole's horizon will disintegrate and they will slowly disappear and go to some unknown place in the density of the black hole. About which intellectual scientists do not know anything till now
Types of Black Holes
There are many types of black holes in the universe which are identified due to their unique properties.
The star whose mass is a few times larger than our Sun and due to gravitational contraction eventually became a black hole. It is called the stellar-mass black hole.
A black hole that is formed in the center of the galaxy i.e. the galaxy and whose density is immense which is very large is called a supermassive black hole. The mass of such black holes is millions of times greater than our Sun. There is a supermassive black hole in the middle of our Galaxy Milky Way whose mass is 10 million times that of our Sun.
There are also black holes whose mass is less than that of our Sun and are formed not due to gravitational contraction but due to compressing their center hard matter and heat. It is also called Pre Module or Small Black Holes. Regarding these people, black holes, scientists believe that they must have been created with the origin of the universe. According to intellectual scientist Stephen Hawkins we can learn a lot about the initial state of evidence by studying such black holes.
Friends, the question that arises in the minds of many of us is that black holes also absorb light, and because of which they seem invisible in the universe, how do scientists finally detect black holes? According to Mitchell, the Black Holes exert their own gravitational influence on the celestial bodies near them, despite being from disturbance. In such a situation, it is dark in the middle but the things around it are seen pulling towards that darkness.
