Black Hole: Space Monster [ English]

Nowadays, when anyone sees the sky over their head, they must be overwhelmed by nature’s beauty and elegance. Many Poets write their love for this through their poems. And many scientists try to look deeper into the reality of this. No matter how old you are, the universe and night sky attract all of us toward themselves.

There are some monsters that fascinate us very much through their mysteries. And it’s human nature that we go for mysteries. These monsters are nothing but Black Holes. If you go anywhere in this world and start talking about space and the universe, it’s a hundred percent sure that one will start talking about these no matter if he knows them or not. The popularity of these monsters is so much that even a street person can talk surface-level things about them.

Today, we will understand what actually this black hole is? How did this form? What will happen if someone goes inside a black hole? And does it provide some sort of short path to travel through space-time fabric? Everyone is fascinated by these questions at any moment of life. So now this is the right place to quench your thirst for knowledge.

To know about Blackhole first we need to know about stars and Chander Shekhar limit. Space is full of cosmic dust, when somehow light’s pressure falls on these cosmic dust particles they start rotating around each other and start forming a compact structure. Due to this compact structure, high-pressure energy is generated inside the core of those dust clouds. When that energy crosses a certain high limit, a nuclear reaction starts, and eventually a star forms that shines the region. But every star does not end up as a black hole, so what is the deciding factor? Deciding factor is known as Chandrasekhar Limit (CSL) which was given by an Indo-American Physicist Subramanyam Chandrashekhar in 1929. This Chandrasekhar Limit tells us that if the mass of a star is greater than or equal to 1.41 times the mass of the sun, then that star will end up as a black hole. When a star gets shrunk to its characteristic radius that its radius very small to its real radius, the black hole forms. Earth can never become a black hole because it is not satisfying the Chandrasekhar limit, but if we take a hypothetical example where we want to convert the earth into a black hole then we need to compress the earth to the size of a cricket ball. At this stage, the earth has infinite mass compared to its size and this can create significantly big curvature in space so that everything around it starts falling into it.

A black hole is an extremely dense object in a space that has a tremendous amount of gravitational force. Black holes are so dense that these will provide extreme curvature to space and as a result, we get a tremendous gravitational pull. Due to this high gravitation, it starts to attract the other objects towards itself. A black hole is like a big dog hole in a river and all of the river water is falling into it. So like this dig hole black hole in space attacks other cosmic objects into it. If someone starts going into a black hole then there happens a strange thing, when he approaches a black hole its the nearest part to the black hole feels extremely intense gravitational pull ass compared to the farthest part that objects start being elongated and look like spaghetti and eventually this strong pull tore that object apart and engulf that. This is called Spaghettification. The Centre of a black hole is called a singularity where the space and time part becomes zero and we don’t have any solution for blackhole mathematics at the center.

Now the question arises that does it provides a short path for our space journey? The answer is no. Because the boundary of the black hole gravitational pull is so strong that it tears you apart. So there is no point in entering into it and travels to another point of space. But there are some theories that tell us about Wormhole, which is nothing but a black hole, which is so dense that it tears the space-time fabric and makes a hole patch there. So many wormhole theories assume that this may act as a superfast tunnel for traveling in space. But this is just a mind fantasy because we don’t have Physics knowledge to support this. Because when we start applying our current physics knowledge to the interior of the black hole, then there is an interesting but vague thing that our space calculations turn into time part and time calculations turn into space part, which means our current understanding of physics is not sufficient to study the black hole. Physicists are working on alternative theories that may help us in the future, but we have very limited knowledge about blackhole.

Finally, I just want to say that the black hole is a very fascinating topic to study, grow our imagination and test our limits. So if you are interested in physics, want to know about our universe, have patience, zeal that you can put in hard work, and, most importantly, imagine, you are most welcome into this world of beauty, glory, and divinity.
