Black hole is amazingly interesting and terrible
Black hole , Amazingly Interesting and Terrible
A black hole is an astronomical structure whose gravitational field is so powerful that nothing, including light, can survive its stretch. There is a boundary around a black hole called the event horizon, in which objects can fall but nothing can come out. Black hole is a wonderful structure of the universe which holds many mysteries in itself.

Who first discovered black holes? https://sattelliteworld.blogspot.com/2020/06/stephen-william.html
Let us discuss in detail the black hole that remains a constant puzzle for space scientists. Professor John Mitchell was the first scientist to reveal his views to the world about the black hole. John Michel was a teacher at Cambridge University and gave his views on black holes in 1783. He had a detailed description of black holes in 1796 by French scientist Pierre Simon in his book 'The System of the World'. mentioned . A black hole is a structure whose gravitational force is so strong that even light cannot pass across it, and swallows everything inside its gravitational realm. Not only this, as much as we go closer to the black hole, the time is greatly reduced and there is no existence of time inside the black hole. A black hole is a body with very high density and mass.
Black hole and Galaxy
What happens if a person goes into a black hole?
If we suppress any object in the universe and make it very small, then its density and mass will make its gravitational force so strong that it will not be possible to let light out of it and that thing will be called a black hole. If our Earth's density increases too much and presses the entire Earth to 1.5 cm. If done, it will become a lacquer a the Sun, which is 13 million times larger, is pressed into the shape of a pea, it will also become a black hole. But remember that density is much more important than mass in a black hole and we know that the Earth and the Sun cannot shrink in this way because neither the mass of the Earth nor the force of gravity nor the Sun but our Sun If there is a star hundreds of millions of times larger than its mass and density, it can become a black hole by its characteristics. Black holes are often formed by stars.
What is inside a Blackhole?
Let us understand how the stars are formed before understanding the construction of the lake hole. The stars are born from the clouds of gas and gas present in the galaxies of the universe. These clouds made of dust and gas in the universe make up the nebula. The nebula has the highest amount of hydrogen and is about 25% hyaliven and also contains a very small amount of other heavy elements. When these clouds made of tenon and gas, ie, the nebula, increase in valence, the vadal starts to shrink due to its gravity and the temperature inside it increases so much that the nucleus of hydrogen starts colliding and the nucleus of holium And due to movement and contraction, it also converges to the same shape as a spherical or spherical and thus a star is formed. But many millions of years also go into this process, our Sun was also formed in this way. The gravitational stars of the stars remain in equilibrium with the intense heat emanating from the heat nucleus fusion. Therefore, when the hydrogen present in the stars is exhausted, it gradually cools down stars with mass 1 times the mass of their exhausted solar mass, which cannot handle itself against its own gravity, inside such a star An explosion occurs which is called a 'supernova'. After this explosion, if any residual residue of that wire survives, it becomes a highly blessed neutron star. Due to the immense gravitational pull on such stars, the star starts to shrink or vibrate 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 In itself, it becomes invisible due to the existence of space and time being erased. These are the invisible bodies that we call 'lake holes'. The entire mass of a neck hole resides in a small point called 'central singularity'.
The circular boundary around this point is called 'Evette Horizon. No light or any object can go outside this Evet Horizon and where time does not even exist. According to Einstein's Varyal Vary of Relativity, an observer standing at a certain range away from the horizon of this jock hole will be very slow and slow and Ka's time will be very chaotic. Remember that time is absolute and the flow of time is different at different places in Prayan. That is, the time on earth, which is moving far away in Hamidmand, will be moving in motion, it is called time italon.
An object falling inside a black hole's horizon will disintegrate the molecules of any object and there it will gradually disappear and go to some unknown place in the black hole texts. About which physical scientists do not know anything till now

There are many types of black holes in the universe that are identified due to their specific qualities. This is the star whose mass is more than our sun, and due to gravitational contraction, it is eventually called a black hole, it is called 'Steller Mass Black Hole'. Such black hole, which is produced in the center of the Galaxy and whose density is immortal, it is called 'Supermasive Black Hole'. Its mass is more than our sun. Our Galaxy is a Super Massiv Black Hole in the middle of the Milky, whose mass is more than one million times more than our sun. There are some black holes whose mass is less than our sun and whose construction is not due to gravitational contraction but due to the substance of its center and heat. It is called 'Primodel or Small Black Hole'. Regarding these small black hole scientists believe that their construction would have been with the origin of the universe. According to physical scientist Stephen Hawking, we can learn a lot about the initial stage of the universe by studying a black hole. Many of us
Astronomers have so far identified 3 types of black holes:
1.Stellar Black hole - small but deadly
2.Super massive Black hole - the birth of giants
3.Intermediated Black hole - stuck in the middle
The question that arises in the minds of many of us is that black holes also absorb light and because of which they appear invisible in the universe, how do scientists finally detect black holes. According to Mitchell, black holes, despite being invisible, exert their gravitational influence on the nearest celestial bodies around them. In such a situation, there is darkness in the middle, but everything around it appears to be pulling towards that darkness. Sometimes, there are two stars or two planets orbiting each other in the universe, between which there is a huge black spot. In this state, there seems to be a black hole there. Sometimes, a black hole is seen swallowing the objects of a visible constellation or Galaxy towards it. In this state the black hole is clearly confirmed. Let us briefly know some other interesting facts of black holes here.
Where do things go in a black hole?
Black holes are not really holes. It is just a remnant of a dead star, billions of years, billions of years, the end of a star and it is born as a black hole. Remember here that not all stars become black holes. After the end of some wires, they move in a different state Black holes do not leave any celestial bodies around them That planet can swallow the small planet comet or the entire galaxy.
It should be noted here that the black hole will only do anything that comes in its gravity. No object can go outside its gravitation. Black holes have been written about since the time of Mitchell. But the first black hole Cygnus X-1 to appear to the world with scientific explanation
Some interesting things related to black holes :
- Albert Einstein first predicted the black hole in 1916
- The term black hole was coined in 1967 by American astronomer John Wheeler.
- For many years black holes were known only as theoretical objects.
- In 2019, in association with the Event Horizon Telescope(EHT), the black hole was photographed and the first photo was releasd .The Event Horizon Telescope placed a black hole in the center of the Galaxy M-87

It is impossible for light to go outside the black hole ever because a black hole has an infinite gravitational force due to its immense density and because of this infinite gravitational force, light cannot even go outside the black hole.
Unlimited gravity and immense density also reduce the effect of time inside the black hole's event horizon, and in this case, as we move closer to the center of the black hole, time slows down a lot and the black hole There is no existence of time in the center of '.
• Event Horizon means that any celestial body will pull the gravitational force of a black hole as soon as the black hole goes within a limit of gravity and not only that, even if a human comes around the event horizon, his body will stretch. Due to this the tall will be wide and distorted in an extraordinary way.
• The nearest black hole V616 Mon from our Earth is 27,000 light years away, but this black hole has no effect on our Earth and Solar System because its effect cannot reach here due to such distance.
• Our Galaxy is a massive super mass black hole in the center of the Milky Way or Milky Way. That black hole is 30000 light years away from our solar system and is about 30,00000 times bigger than our sun. Now imagine yourself how much his gravitational force will be and how far his boundaries will be spread.
