The first picture of the black hole: impossible when it became a reality-Part One
Today's day will be remembered in the history of astrophysics. People thought that they would be left unseen forever, the unseen appeared today. For the first time in history, black holes have been created. Today, the picture has been opened for everyone. Stephen Hawking would have been happier if he was alive. He gave two lectures on the BBC in the Blackhole. Jokingly said,
If someone can actually detect black hole, then I'll get the Nobel! He could not get awards in his hands, but he achieved something bigger than Nobel. What is he looking at from? Who knows! The event Horizon, a telescope, has taken this picture of the black hole. This Novelleliscope has taken pictures of the black hole in the center of the galaxy Messier 87. The director of this project and astrophysicist Shepard Dolman of Harvard-Smithsonian Center for Astrophysics in Cambridge, said,
People are thinking that people are impossible to see, today we see that we are Just not seen, I have taken pictures of it! In fact, the story of Einstein came to the fore in the beginning of the black hole. The story of Chandrasekhar goes away. But in 1939 Albert Einstein wrote a paper, whose content was- The stars can never collapse in gravity and collapse. Because, it is not possible to compress the material under a certain limit.
Many scientists did not agree with Einstein's opinion. And the biggest opposition was John Wheeler, the American scientist. In many ways, the protagonist of the story of Black Hole, who is actually the protagonist of the story of Black Hole. From the 1950s to '60, he said with great emphasis that at one time almost all the stars would collapse on their own. And if this possibility is true, then what kind of problem can it be for theoretical physics,He also indicated that. In addition, he was able to predict the characteristics of these stars or black holes in the stars. However, Chandrashekhar started it.
Throughout most of the lifetime of a common star, in a few billion years the star can retain itself against its own gravitational pull. The energy that takes place in it, it comes from the thermal pressure caused by the nuclear fission due to the constellation. And, in this fusion process, hydrogen is converted into helium.
According to NASA, the stars are like a preacher cooker. The explosive force that creates the result of the nuclear fusion reaction on the stars, creates an outward pressure. This outward pressure prevents gravity. For this reason, gravity can not drag the internal elements of the stars into the inner side.
Slowly the star's nuclear fuel ran out. Then the star started to shrink. At this time, some stars have found a way to keep themselves. The way is to become a 'white dwarf' star. Subhavanaan Chandra Shekhar, for the first time in 1930, showed us that the mass of the white dwarf star may be 1.4 times higher than the sun.
It is a matter of saying, what if the mass of a star is more than that?
The stars will become constricted in the gravitational pull caused by its own body, in the black hole. The biggest feature of this black hole is that here gravity is very strong. Self lighting can not come out of here. But Einstein's theory of relativity recognizes that the most dynamic object in the universe is the light.
