Mostly all of us have heard about the black hole in the space. But do we ever try finding what Is black hole? How it emerged? How the scientists came to know about this? The scientists have actually trapped the first ever image of black hole. But firstly what is black hole? Black hole is the region of the space-time which exhibit intensively strong gravitational force on the objects that once any object falls into this hole, the object cannot escape from inside it. Isn’t it seems like a fantasy? But that’s the truth.
Now the question is How does the black hole emerged and from where? Generally, the black holes are formed when the heavy objects in space like stars gets gravitationally collapsed with each other. The Black Hole was first founded in 1916 by Karl Schwarzschild.
On April 10, 2019, Katie Bouman, Computer Scientist at MIT, USA led the development of algorithm useful for imaging the Black Hole called M87 (Messier 87) Black Hole and the amazing fact is that the mass of this Black Hole is around 7 times that of the Sun. Almost 5 Peta bytes of data was used to generate the actual image of M87 Black Hole.
The actual image of the M87 Black Hole
According to the theory, there are three types of black holes: Stellar, Supermassive, and Miniature Black holes- depending on the mass. The three are distinguished on the basis of how they are formed. The Stellar Black hole is formed when the massive stars collapses. The Supermassive black holes are likely the byproducts of the galaxy formation as they exist in the centers of the most galaxies, including our own galaxy, the Milky Way. These black holes have masses equivalent to that of billions of Suns and M87 is one of them. Now talking about the Miniature black hole, they have never been discovered but would have mass smaller than that of our Sun. Did you know, the sci-fi movie “Interstellar” revolves around the black hole. One more interesting fact is that if a person unintentionally falls into the black hole, the strong gravitational forces of the black hole will stretch the body of the person, making it look like Spaghetti (Italian Noodle). Quite weird. Isn’t it? Scientists at NASA in October, 2018 for the first time in history, spotted the light coming out of the black hole which contained electromagnetic radiations in it and travelled with the speed of 60 Mm/s which is around 20 per cent of the speed of light. The black holes in the space-time region signifies how vast and incredible our universe is. There are infinite number of galaxies in the space and have infinite black holes in them and these fascinating creations (that actually we are not aware of many) reflects the immense power of the nature.
